SEAC SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE
Agenda 104th meeting on Friday 5th March 2010
SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE Draft Minutes of the 103rd Meeting held on 24th November 2009 at Nobel House, 17 Smith Square, London SW1P 3JR.
ITEM 3 – CURRENT ISSUES 6. SEAC was updated on the Strain Typing Expert Group report on a suspected BSE case in a historic Scottish goat. The goat had originally been diagnosed with scrapie in 1990. However, retrospective tests have now confirmed that the goat isolate was indistinguishable from BSE. The results do not affect the SEAC position statement on the Potential Human Health Risks from Changes to Classical Scrapie Controls published in February 2008. That statement concluded that if BSE was confirmed, the fact that the animal was born prior to the introduction of the ruminant feed ban meant it could have been exposed to BSE contaminated feed.

7. Atypical scrapie has been confirmed in a sheep from the New Zealand (NZ) national flock. NZ authorities have stated that because atypical scrapie is distinct from classical scrapie, they consider that NZ remains “free from scrapie.”

8. The Advisory Committee on the Safety of Blood, Tissues and Organs has recommended that blood prion filtration should be used to treat patients with no prior evidence of dietary exposure to BSE. SEAC noted that the Department of Health Ministers were currently considering this recommendation.

10. In light of the recent high profile dismissal of a Government scientific advisor, the Chair said he would be concerned if any member of a Scientific Advisory Committee (SAC) were to be dismissed for expressing scientific opinions whether or not these contradict Government policy. It was added that SEAC adheres to the principles of the Philips’ report and clearly recognises the distinction between risk management and risk assessment: this distinction may not be so clearly defined in the work of other SACs. The Chair said that there was to be a meeting of scientists engaged in work on government committees and that Professor Graham Medley would be representing SEAC.

ITEM 4 – UPDATE ON CJD EPIDEMIOLOGY
11. Professor Richard Knight (National CJD Surveillance Unit) provided the Committee with the latest figures for the number of clinical vCJD and sporadic CJD (sCJD) cases. To date there had been 170 definite or probable clinical cases of vCJD in the UK - 167 from probable dietary infection with BSE and three from probable vCJD infection via transfusion of blood from donors who later developed vCJD. Of the 150 cases tested all were codon 129MM. Four cases are still alive. The number of deaths from vCJD peaked at 28 in 2000 and had since declined with two known deaths so far in 2009. The median age of death is 30 years of age.
12. Professor Knight explained that elsewhere in the world 47 clinical vCJD cases have been reported with 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan. Infection was presumed to have occurred in the UK in respect of two Irish and two USA cases, one French case, one Japanese case and one Canadian case.
13. Professor Knight explained that one MV genotype case had been classified as possible vCJD as clinical features were consistent with the disease. However, it had not been possible to undertake neuropathological examination post mortem so the diagnosis could not be confirmed. The clinical profile of this MV case was consistent with that observed for MM cases.
14. Professor Knight summarised data on sCJD cases stating that from May 1990 to September 2009, 1080 cases of sCJD had been identified in the UK with a mean age at death of 67 years and genotype distribution of 63% MM, 19% MV and 18% VV at codon 129 of the prion protein gene.
15. Professor Knight also provided a brief report on the novel human disease known as Protease-Sensitive Prionopathy (PSPr). The initial eleven cases described by Gambetti2 exhibited a mean age of onset of 62 years and mean disease duration of 20 months. Eight out of ten had a family history of dementia and were codon 129VV. Cases had minimal spongiform change and minimal immunohistochemical stained PrP deposits with distinct patterns in the cortex and cerebellum. Western Blot (WB) also shows a minimal amount of PrPres present. Further studies by Gambetti have now identified codon 129MV and MM cases which have a longer disease duration and exhibit some PK resistance. The cases did not have clinical profiles typical for sCJD. A UK case and a Dutch case have also been identified, with characteristics not inconsistent with the Gambetti studies.
16. Professor Knight added that due to the unique clinical presentation of the disease it was likely that at least some cases of disease would not be identified for referral, making it hard to obtain complete data on this disease. However, it was likely that a case would be identified as a prion disease at autopsy and the WB currently used would be able to identify the unique profile which categorises this disease. A retrospective review of the NCJDSU brain bank is underway to look for more cases.
17. A Member asked whether the recent review of neuropathology archives in the UK would have identified PSPr. Professor Knight responded that it would be dependent on the type of WB used at the time which is currently not known. The use of appropriate WB methodology would be an issue in accurately identifying the relevant characteristics.
18. One Member was not convinced by the characterisation of this disease, adding that clinical cases classified as Alzheimer’s Disease have shown similar laddering profiles in WB, protease resistant fragments and the presence of abnormal PrP. The disease has, to date, not been shown to be transmissible which means it should not yet be categorised a prion disease under the current terminology.
19. Summing up, the Chair noted that it was clear that more information was required to fully characterise and fill knowledge gaps regarding this disease. It was important that its unique pathology be more widely recognised to enable future diagnosis and enable tissue collection during autopsy procedures. SEAC will keep a watching brief on emerging data which may characterise the disease further.

ITEM 74 – CATEGORY 3 ANIMAL PRODUCTS IN FERTILISERS (SEAC 103/3)
29. The Chair reminded Members that in 2005 the Committee had considered a release assessment which evaluated the amount of potential infectivity available in the soil of non-pasture land following the application of Category 3-derived5 fertiliser.
European Regulations are now being renegotiated and Defra are considering whether it is appropriate to seek a relaxation of rendering requirements (see paper 103/3). In order to inform this consideration, Defra commissioned a full Risk Assessment (RA) which was completed in 2008 which SEAC is now invited to consider.
snip...
ITEM 8 – FUTURE OPERATION OF SEAC (SEAC 103/4)
40. The Chair reminded Members that he had recently written to them about proposals on the future operation of SEAC. The Chair asked Members of the Committee for their views on the suggestion that SEAC should henceforth aim to conduct the majority of its business in correspondence, only meeting when there was a major new development, or a significant amount of business over a short period.
41. Some Members were in favour of what was being proposed and suggested that business conducted by e-mail could usefully be confined to a scheduled period, or periods, in the year.

SEAC 104/2
ESTIMATING THE PREVALENCE OF SUBCLINICAL vCJD
ISSUE
1. The prevalence of subclinical vCJD in the UK is highly uncertain. Current estimates are based on the Hilton et al data on abnormal prion protein (PrPvCJD) in stored appendix samples, however the National Anonymous Tonsil Archive (NATA) study is on-going, and a further study of appendices has been commissioned. In addition, a pilot to assess the feasibility of a post mortem study to test spleen tissue has also been commissioned. The NATA data are currently within the confidence intervals of the Hilton data, but there remains a possibility that once completed, the data from these studies might be discrepant.
2. All samples in the NATA survey (over 80,000) have tested negative by EIA. However, one of 10,000 samples re-tested by IHC has given a positive result in one follicle. Extensive further testing of this sample has produced negative results.
3. Prevalence of infective material in subclinical individuals is a key factor determining the risks of secondary vCJD transmission via surgery, or donated blood, tissues or organs. To assess these risks, presence of PrPvCJD has been used as a surrogate indicator of infectivity, though the relationship between the two is not fully established.
4. In addition, risk assessments have assumed that in principle, the same “prevalence” would drive all transmission risks. For example, if the prevalence of sub-clinical infection was “1 in x”, then 1 in every x surgical procedures encountering any lymphoid tissue (e.g. tonsil, appendix or spleen) would meet with infective material. Similarly, 1 in every x blood donations would be infective. At present, this means that assessments are based primarily on the Hilton et al appendix results. This approach may not be appropriate if the presence of PrPvCJD varies markedly by site, and possibly over time. Nor would one necessarily expect different “prevalence studies” to be mutually consistent.
5. The Committee is asked to consider the following questions:

SEAC104/3
VCJD TRANSMISSION VIA BLOOD COMPONENTS: CAN A MORE PLAUSIBLE RANGE OF SCENARIOS BE ESTABLISHED?
ISSUE
1. The Department of Health (DH) uses a wide range of possible scenarios for blood borne transmission of vCJD, to support risk management. However, a number of those scenarios overpredict the number of clinical cases of vCJD that have resulted so far from blood-borne transmission. DH analysts have drafted the paper attached at Annex A, which assesses the possibility of revising these scenarios so as to be more consistent with the available “positive” and “negative” evidence on human transmission, as well as with the findings of animal studies.
2. DH would like SEAC’s advice on the establishment of a more plausible range of scenarios. SEAC is asked to consider:
* Acknowledging the crude nature of the calculations offered, have any major factors been misrepresented or overlooked?
* Are members aware of any more sophisticated analysis that addresses the consistency of blood-borne transmission scenarios with observed case numbers?
* Given the apparent consistency problem, can the existing range of inputs on infectivity, prevalence of infective donors and susceptibility to disease be reconciled with the data by invoking plausible further hypotheses - and if so, what are they?
* If not, should some of the existing input ranges now be regarded as implausible - singly or in combination - and if so, which?
* Should additional scenarios now be regarded as plausible - and if so, how should the current input ranges be extended?
* Can the Committee suggest any further lines of investigation that could be implemented relatively quickly, and could throw further light on the numbers of vCJD cases likely to result from blood-borne transmission?
THE DH SCENARIOS
3. The current scenarios are based on three main inputs:
• the prevalence of infective donors;
• vCJD infectivity (levels and timing) in blood components; and
• susceptibility of recipients to clinical disease.

Greetings,
HAVE we come to a point to where sub-clinical disease is an acceptable factor ???
LEGALLY, is it o.k. to be sub-clinically infected from a contaminated product ???
IF SO, what is the legality from the second passage infection from that sub-clinical host to clinical infection via the pass it forward and or friendly fire mode of transmission for any iatrogenic Transmissible Spongiform encephalopathy to second, third, fourth passage ???
I THOUGHT also, it would be nice if SEAC would have included the figures on sporadic CJD in there report, which they failed to do. they seem to come up with all these mathematical formulas, but fail to show you the numbers. so please allow me to show you some numbers on sporadic CJD ;
IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;
However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).
IF we go further and look at some of the other documented BSE countries, you will the increase of sporadic CJD there as well ;
Canada from 2 to 25
France from 35 to 108
Germany 21+ to 96
Italy 27 to 76

CJD RISING SWITZERLAND
CJD is a predominantly sporadic disorder but can also occur as a dominantly inherited or infective condition. Only one of the 26 most recent confirmed cases was identified as carrying a disease related mutation of the PRNP gene, none had identifiable iatrogenic exposure, and none resembled variant CJD. Thus 25 of the 26 cases appear to be sporadic cases. Sporadic CJD is distributed worldwide with a reported incidence of about one in a million per year. Raised awareness of the disease in recent years could account for an increase in reported cases of CJD, although neither an increase in the average age of patients nor more frequent recognition of CJD amongst residents of nursing homes (where dementing illness is prevalent and misdiagnosis might be expected) were seen in the Swiss cases. Moreover, improved ascertainment as an explanation for the observed increase would imply levels of under-reporting in countries other than Switzerland, which appear implausible. The authors of the Lancet report suggest that the rise in cases might be due to some form of unidentified iatrogenic transmission or to exposure to a zoonotic source of infection, though cases do not resemble variant Creutzfeldt-Jakob disease (vCJD). The ongoing surveillance of CJD in Switzerland and the rest of Europe is essential to monitor the situation to see if this rise is sustained in Switzerland, and if a similar rise occurs in other countries (see http://www.eurocjd.ed.ac.uk).

Prion data suggest BSE link to sporadic CJD Declan Butler
Predicting the number of cases of Creutzfeldt-Jakob disease (CJD) in people as a result of transmission of bovine spongiform encephalopathy (BSE) has just got more difficult.Whereas it was thought that BSE only caused a new form of the disease called variant CJD (vCJD), a study in mice from a team led by John Collinge at University College London suggests that it may also cause a disease indistinguishable from the commonest form of classical, or 'sporadic', CJD (E.

Mouse model sheds new light on human prion disease

Professor John Collinge said We are not saying that all or even most cases of sporadic CJD are as a result of BSE exposure, but some more recent cases may be the incidence of sporadic CJD has shown an upward trend in the UK over the last decade. While most of this apparent increase may be because doctors are now more aware of CJD and better at diagnosing it, serious consideration should be given to a proportion of this rise being BSE-related. Switzerland, which has had a substantial BSE epidemic, has noted a sharp recent increase in sporadic CJD.

2. Sporadic CJD normally occurs in people in their 50s and 60s although it can occur more rarely in younger age groups. Until this year the youngest case of sporadic CJD in the UK had been in a 34 year old. Other countries, howver, have reported sporadic CJD in teenagers. Those we know about are;
* in the USA, a 16 year old in 1978;
* in France, a 19 year old in 1982;
* in Canada, a 14 year old of UK origin in 1988;
* in Poland cases in people aged 19, 23, and 27 were identified in a retrospective study (published 1991), having been originally misdiagnosed with a viral encephalitis;
* Creutzfeldt's first patient in 1920 was aged 23.

Abstract
Background: Sporadic Creutzfeldt-Jakob disease (CJD) is a condition predominantly affecting older age groups, with cases aged less than 45 years rare and an age at onset or death of less than 20 years exceptional.
Methods: Data from the systematic study of sporadic CJD in the UK are available from 1970 onwards. Clinical and pathological data are reviewed in order to identify atypical cases, including those at the extremes of the age range of sporadic CJD. Detailed analysis of atypical cases is undertaken and in selected cases laboratory transmission studies are carried out in order to provide information on the characteristics of the infectious agent.
Results: In the UK two cases of sporadic CJD in adolescents have been identified, dying aged 16 and 20 years. The first case predated the epidemic of bovine spongiform encephalopathy and the characteristics of the second case, including laboratory transmission studies, are consistent with a diagnosis of sporadic rather than variant CJD.
Conclusion: The cases in this report indicate that sporadic CJD can develop at a very young age, that variant CJD is not the only form of CJD occurring in this age group and that neuropathological examination is essential to accurate diagnosis of human prion disease.

ALSO, SEAC STATES HERE ;
20. The pathogenesis of BSE and classical scrapie in sheep and BSE in non-human primates is generally considered to be a reasonable model for the pathogenesis of vCJD in humans....
IF THAT is the case, then why is it not the same for sporadic CJD and typical scrapie, because typical scrapie transmits to primates by their non-forced oral consumption of infectious material, and or the atypical Nor-98 Scrapie (cause it's either scarpie or bse, you have to call it something, or name it something else), which is very similar and is encoded by distinct prion types very similar to sporadic CJD type 1 ?

Similarities between Forms of Sheep Scrapie and Creutzfeldt-Jakob Disease Are Encoded by Distinct Prion Types

OH, and about the figures SEAC presented for nvCJD in the USA, what's that all about ?
12. Professor Knight explained that elsewhere in the world 47 clinical vCJD cases have been reported with 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan. Infection was presumed to have occurred in the UK in respect of two Irish and two USA cases, one French case, one Japanese case and one Canadian case...
I DON'T understand WHY SEAC would state three in the USA, and then stipulate that TWO were presumed to have occured in the UK, BUT fail to stipulate that the 3rd was either SAUDI ARABIA linked, or USA linked ? it was just odd to me how it was worded. SEAC made sure the UK source for the USA was the UK, but fail to explain that for the Saudi Arabia case of nvCJD...see next link below;

Session: International Scientific Exchange
Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America
update October 2009
T. Singeltary
Bacliff, TX, USA
Background:
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods:
12 years independent research of available data
Results:
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion:
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

ITEM 4 – UPDATE ON CJD EPIDEMIOLOGY
11. Professor Richard Knight (National CJD Surveillance Unit) provided the Committee with the latest figures for the number of clinical vCJD and sporadic CJD (sCJD) cases. To date there had been 170 definite or probable clinical cases of vCJD in the UK - 167 from probable dietary infection with BSE and three from probable vCJD infection via transfusion of blood from donors who later developed vCJD. Of the 150 cases tested all were codon 129MM. Four cases are still alive. The number of deaths from vCJD peaked at 28 in 2000 and had since declined with two known deaths so far in 2009. The median age of death is 30 years of age.
12. Professor Knight explained that elsewhere in the world 47 clinical vCJD cases have been reported with 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan. Infection was presumed to have occurred in the UK in respect of two Irish and two USA cases, one French case, one Japanese case and one Canadian case.
13. Professor Knight explained that one MV genotype case had been classified as possible vCJD as clinical features were consistent with the disease. However, it had not been possible to undertake neuropathological examination post mortem so the diagnosis could not be confirmed. The clinical profile of this MV case was consistent with that observed for MM cases.
14. Professor Knight summarised data on sCJD cases stating that from May 1990 to September 2009, 1080 cases of sCJD had been identified in the UK with a mean age at death of 67 years and genotype distribution of 63% MM, 19% MV and 18% VV at codon 129 of the prion protein gene.
15. Professor Knight also provided a brief report on the novel human disease known as Protease-Sensitive Prionopathy (PSPr). The initial eleven cases described by Gambetti2 exhibited a mean age of onset of 62 years and mean disease duration of 20 months. Eight out of ten had a family history of dementia and were codon 129VV. Cases had minimal spongiform change and minimal immunohistochemical stained PrP deposits with distinct patterns in the cortex and cerebellum. Western Blot (WB) also shows a minimal amount of PrPres present. Further studies by Gambetti have now identified codon 129MV and MM cases which have a
longer disease duration and exhibit some PK resistance. The cases did not have clinical profiles typical for sCJD. A UK case and a Dutch case have also been identified, with characteristics not inconsistent with the Gambetti studies.
16. Professor Knight added that due to the unique clinical presentation of the disease it was likely that at least some cases of disease would not be identified for referral, making it hard to obtain complete data on this disease. However, it was likely that a case would be identified as a prion disease at autopsy and the WB currently used would be able to identify the unique profile which categorises this disease. A retrospective review of the NCJDSU brain bank is underway to look for more cases.
17. A Member asked whether the recent review of neuropathology archives in the UK would have identified PSPr. Professor Knight responded that it would be dependent on the type of WB used at the time which is currently not known. The use of appropriate WB methodology would be an issue in accurately identifying the relevant characteristics.
18. One Member was not convinced by the characterisation of this disease, adding that clinical cases classified as Alzheimer’s Disease have shown similar laddering profiles in WB, protease resistant fragments and the presence of abnormal PrP. The disease has, to date, not been shown to be transmissible which means it should not yet be categorised a prion disease under the current terminology.
19. Summing up, the Chair noted that it was clear that more information was required to fully characterise and fill knowledge gaps regarding this disease. It was important that its unique pathology be more widely recognised to enable future diagnosis and enable tissue collection during autopsy procedures. SEAC will keep a watching brief on emerging data which may characterise the disease further.

>>>12. Professor Knight explained that elsewhere in the world 47 clinical vCJD cases have been reported with 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan. Infection was presumed to have occurred in the UK in respect of two Irish and two USA cases, one French case, one Japanese case and one Canadian case.<<<
>>>Two of the three U.S. cases, two of the four cases from Ireland and the single cases from Canada and Japan were likely exposed to the BSE agent while residing in the United Kingdom. One of the 25 French cases may also have been infected in the United Kingdom.<<<
>>>There has never been a case of vCJD that did not have a history of exposure within a country where the cattle disease, BSE, was occurring.<<<
>>>vCJD Cases Reported in the US Three cases of vCJD have been reported from the United States. By convention, variant CJD cases are ascribed to the country of initial symptom onset, regardless of where the exposure occurred. There is strong evidence that suggests that two of the three cases were exposed to the BSE agent in the United Kingdom and that the third was exposed while living in Saudi Arabia.<<<

Third case of vCJD reported in the United States
Editorial Team (eurosurveillance.weekly@hpa.org.uk), Eurosurveillance editorial office
A clinical diagnosis of variant Creutzfeldt Jakob Disease (vCJD) was confirmed after brain biopsy investigations in a United States (US) resident and reported in November [1]. The patient is a young man who grew up in Saudi Arabia and lived in the US since late 2005. Before that he visited the US once in 1989 and several times after 2001. He has never visited any country in Europe or received a blood transfusion nor has he undergone any neurosurgical procedure. This vCJD case is the third in a US resident. The previous two patients both grew up in the United Kingdom (UK), and this is where they were believed to have been infected [2].
In Saudi Arabia, the first and only previous case of vCJD was reported in 2005. This was suspected to be related to consumption of meat contaminated with the prion agent which causes bovine spongiform encephalitis in cattle (BSE). The European Food Safety Authority (http://www.efsa.org) has not published a geographical BSE risk assessment for Saudi Arabia [3] and there have been no cases of BSE in cattle reported by Saudi Arabia to the World Organisation for Animal Health (http://www.oie.int). Although the UK is not the only potential beef exporter to have had a BSE epidemic, it remains plausible, subject to Saudi Arabia's import policy, that contaminated beef was inadvertently imported from the UK to Saudi Arabia in the period before 1996 (when the EU banned the export of UK beef and cattle).
Based on this patient's history, the occurrence of a previously reported case of vCJD in Saudi Arabia, and the expected length of the incubation period for food-related vCJD, the most likely source of infection is thought to be contaminated meat products the patient consumed as a child when living in Saudi Arabia. The patient has no known history of donating blood, and investigations have identified no risk of onwards transmission within the US.
Variant Creutzfeldt-Jakob disease was first identified in the United Kingdom in the mid-1990s. As of November 2006, worldwide there have been 200 vCJD cases: 164 patients in the United Kingdom, 21 in France, four in Ireland, three in the US (including the present case), two in the Netherlands and one each in Canada, Italy, Japan, Portugal, Saudi Arabia and Spain [4]. All patients, except 10 (including the present case) had lived either in the United Kingdom (170 cases) or in France (20 cases). Evidence so far indicates that the most probable source of infection in most cases was consumption of meat products contaminated with the prion agent causing BSE.

Experimental Challenge of Cattle with H-type and L-type Atypical BSE

Background: After the detection of two novel BSE forms designated H-type and L-type atypical BSE the question of the pathogenesis and the agent distribution of these two types in cattle was fully open. From initial studies of the brain pathology, it was already known that the anatomical distribution of L-type BSE differs from that of the classical type where the obex region in the brainstem always displays the highest PrPSc concentrations. In contrast in L-type BSE cases, the thalamus and frontal cortex regions showed the highest levels of the pathological prion protein, while the obex region was only weakly involved.
Methods:We performed intracranial inoculations of cattle (five and six per group) using 10%brainstemhomogenates of the two German H- and L-type atypical BSE isolates. The animals were inoculated under narcosis and then kept in a free-ranging stable under appropriate biosafety conditions.At least one animal per group was killed and sectioned in the preclinical stage and the remaining animals were kept until they developed clinical symptoms. The animals were examined for behavioural changes every four weeks throughout the experiment following a protocol that had been established during earlier BSE pathogenesis studies with classical BSE.
Results and Discussion: All animals of both groups developed clinical symptoms and had to be euthanized within 16 months. The clinical picture differed from that of classical BSE, as the earliest signs of illness were loss of body weight and depression. However, the animals later developed hind limb ataxia and hyperesthesia predominantly and the head. Analysis of brain samples from these animals confirmed the BSE infection and the atypical Western blot profile was maintained in all animals. Samples from these animals are now being examined in order to be able to describe the pathogenesis and agent distribution for these novel BSE types. Conclusions: A pilot study using a commercially avaialble BSE rapid test ELISA revealed an essential restriction of PrPSc to the central nervous system for both atypical BSE forms. A much more detailed analysis for PrPSc and infectivity is still ongoing.

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Authors: T. Singeltary; Bacliff, TX/US
Title: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Body: Background
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and feed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods
12 years independent research of available data
Results
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries.
I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

I look forward to further transmission studies, and a true ENHANCED BSE/atypical BSE surveillance program put forth testing all cattle for human and animal consumption for 5 years. a surveillance program that uses the most sensitive TSE testing, and has the personnel that knows how to use them, and can be trusted. I look forward to a stringent mad cow feed ban being put forth, and then strictly enforced. we need a forced, not voluntary feed ban, an enhanced feed ban at that, especially excluding blood. we need some sort of animal traceability. no more excuses about privacy. if somebody is putting out a product that is killing folks and or has the potential to kill you, then everybody needs to know who they are, and where that product came from. same with hospitals, i think medical incidents in all states should be recorded, and made public, when it comes to something like a potential accidental transmission exposure event. so if someone is out there looking at a place to go have surgery done, if you have several hospitals having these type 'accidental exposure events', than you can go some place else. it only makes sense. somewhere along the road, the consumer lost control, and just had to take whatever they were given, and then charged these astronomical prices. some where along the line the consumer just lost interest, especially on a long incubating disease such as mad cow disease i.e. Transmissible Spongiform Encephalopathy. like i said before, there is much more to the mad cow story than bovines and eating a hamburger, we must start focusing on all TSE in all species. ...TSS

There is a growing number of human CJD cases, and they were presented last week in San Francisco by Luigi Gambatti(?) from his CJD surveillance collection.
He estimates that it may be up to 14 or 15 persons which display selectively SPRPSC and practically no detected RPRPSC proteins.

CJD RISING SWITZERLAND
CJD is a predominantly sporadic disorder but can also occur as a dominantly inherited or infective condition. Only one of the 26 most recent confirmed cases was identified as carrying a disease related mutation of the PRNP gene, none had identifiable iatrogenic exposure, and none resembled variant CJD. Thus 25 of the 26 cases appear to be sporadic cases. Sporadic CJD is distributed worldwide with a reported incidence of about one in a million per year. Raised awareness of the disease in recent years could account for an increase in reported cases of CJD, although neither an increase in the average age of patients nor more frequent recognition of CJD amongst residents of nursing homes (where dementing illness is prevalent and misdiagnosis might be expected) were seen in the Swiss cases. Moreover, improved ascertainment as an explanation for the observed increase would imply levels of under-reporting in countries other than Switzerland, which appear implausible. The authors of the Lancet report suggest that the rise in cases might be due to some form of unidentified iatrogenic transmission or to exposure to a zoonotic source of infection, though cases do not resemble variant Creutzfeldt-Jakob disease (vCJD). The ongoing surveillance of CJD in Switzerland and the rest of Europe is essential to monitor the situation to see if this rise is sustained in Switzerland, and if a similar rise occurs in other countries (see http://www.eurocjd.ed.ac.uk).

Prion data suggest BSE link to sporadic CJD Declan Butler
Predicting the number of cases of Creutzfeldt–Jakob disease (CJD) in people as a result of transmission of bovine spongiform encephalopathy (BSE) has just got more difficult.Whereas it was thought that BSE only caused a new form of the disease called variant CJD (vCJD), a study in mice from a team led by John Collinge at University College London suggests that it may also cause a disease indistinguishable from the commonest form of classical, or 'sporadic', CJD (E.
http://www.nature.com/nature/journal/v420/n6915/full/420450a.html
IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;
However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).
IF we go further and look at some of the other documented BSE countries, you will the increase of sporadic CJD there as well ;
Canada from 2 to 25
France from 35 to 108
Germany 21+ to 96
Italy 27 to 76

Switzerland sporadic CJD ;
Swiss rise in CJD raises concerns over possible BSE link [LONDON] THE LANCET
Plaque attack: Swiss patients have spongiform patterns in the brain typical of sporadic CJD. The number of people dying from Creutzfeldt-Jakob disease (CJD) has risen sharply in Switzerland -- sparking fears of a possible link with bovine spongiform encephalopathy (BSE).
BSE is thought to be the cause of a distinctive form of the brain-wasting disease known as variant CJD. The Swiss cases, in contrast, are standard 'sporadic' CJD. Each year between 1997 and 2000, no more than 11 Swiss people developed CJD. But 19 cases were reported in 2001, and seven were recorded in the first quarter of this year. This is some four times higher than the incidence elsewhere, reports a team led by Adriano Aguzzi of the University Hospital Zurich (M. Glatzel et al. Lancet 360, 139-141; 2002).
The increase could be a mere statistical blip, or it may be due to increased awareness of the disease leading to more diagnoses. More disturbing is the possibility that the cases are linked to the consumption of BSE-infected meat products -- which would mean that the BSE agent can cause two distinct forms of CJD.
Possible links between the Swiss CJD cases and BSE will now be explored by strain-typing experiments in which the disease is transmitted to mice. These tests will take at least a year to complete. "It's the best way to establish or exclude any suspected link," says Moira Bruce of the UK Institute for Animal Health's Neuropathogenesis Unit in Edinburgh.
======================================
Experiences in England and Switzerland -- two countries that discovered mad cow disease in their cattle -- have heightened concerns about the possibility some cases of sporadic CJD are due to consuming mad-cow-tainted beef. Both countries have reported increases in sporadic CJD since mad cow was first detected in British herds in 1986.
Switzerland discovered last year its CJD rate was twice that of any other country in the world. Switzerland had been seeing about eight to 11 cases per year from 1997 to 2000. Then the incidence more than doubled, to 19 cases in 2001 and 18 cases in 2002.

Mouse model sheds new light on human prion disease

Professor John Collinge said We are not saying that all or even most cases of sporadic CJD are as a result of BSE exposure, but some more recent cases may be the incidence of sporadic CJD has shown an upward trend in the UK over the last decade. While most of this apparent increase may be because doctors are now more aware of CJD and better at diagnosing it, serious consideration should be given to a proportion of this rise being BSE-related. Switzerland, which has had a substantial BSE epidemic, has noted a sharp recent increase in sporadic CJD.

Mr Terry Singeltary (Texas, USA) had submitted a question prior to the meeting, asking: “With the Nor-98 now documented in five different states so far in the USA in 2007, and with the two atypical BSE H-base
13 © SEAC 2007
cases in Texas and Alabama, with both scrapie and chronic wasting disease (CWD) running rampant in the USA, is there any concern from SEAC with the rise of sporadic CJD in the USA from ''unknown phenotype'', and what concerns if any, in relations to blood donations, surgery, optical, and dental treatment, do you have with these unknown atypical phenotypes in both humans and animals in the USA? Does it concern SEAC, or is it of no concern to SEAC? Should it concern USA animal and human health officials?”
41. A member considered that this question ............

ITEM 4 – UPDATE ON CJD EPIDEMIOLOGY
11. Professor Richard Knight (National CJD Surveillance Unit) provided the Committee with the latest figures for the number of clinical vCJD and sporadic CJD (sCJD) cases. To date there had been 170 definite or probable clinical cases of vCJD in the UK - 167 from probable dietary infection with BSE and three from probable vCJD infection via transfusion of blood from donors who later developed vCJD. Of the 150 cases tested all were codon 129MM. Four cases are still alive. The number of deaths from vCJD peaked at 28 in 2000 and had since declined with two known deaths so far in 2009. The median age of death is 30 years of age.
12. Professor Knight explained that elsewhere in the world 47 clinical vCJD cases have been reported with 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan. Infection was presumed to have occurred in the UK in respect of two Irish and two USA cases, one French case, one Japanese case and one Canadian case.
13. Professor Knight explained that one MV genotype case had been classified as possible vCJD as clinical features were consistent with the disease. However, it had not been possible to undertake neuropathological examination post mortem so the diagnosis could not be confirmed. The clinical profile of this MV case was consistent with that observed for MM cases.
14. Professor Knight summarised data on sCJD cases stating that from May 1990 to September 2009, 1080 cases of sCJD had been identified in the UK with a mean age at death of 67 years and genotype distribution of 63% MM, 19% MV and 18% VV at codon 129 of the prion protein gene.
15. Professor Knight also provided a brief report on the novel human disease known as Protease-Sensitive Prionopathy (PSPr). The initial eleven cases described by Gambetti2 exhibited a mean age of onset of 62 years and mean disease duration of 20 months. Eight out of ten had a family history of dementia and were codon 129VV. Cases had minimal spongiform change and minimal immunohistochemical stained PrP deposits with distinct patterns in the cortex and cerebellum. Western Blot (WB) also shows a minimal amount of PrPres present. Further studies by Gambetti have now identified codon 129MV and MM cases which have a
longer disease duration and exhibit some PK resistance. The cases did not have clinical profiles typical for sCJD. A UK case and a Dutch case have also been identified, with characteristics not inconsistent with the Gambetti studies.
16. Professor Knight added that due to the unique clinical presentation of the disease it was likely that at least some cases of disease would not be identified for referral, making it hard to obtain complete data on this disease. However, it was likely that a case would be identified as a prion disease at autopsy and the WB currently used would be able to identify the unique profile which categorises this disease. A retrospective review of the NCJDSU brain bank is underway to look for more cases.
17. A Member asked whether the recent review of neuropathology archives in the UK would have identified PSPr. Professor Knight responded that it would be dependent on the type of WB used at the time which is currently not known. The use of appropriate WB methodology would be an issue in accurately identifying the relevant characteristics.
18. One Member was not convinced by the characterisation of this disease, adding that clinical cases classified as Alzheimer’s Disease have shown similar laddering profiles in WB, protease resistant fragments and the presence of abnormal PrP. The disease has, to date, not been shown to be transmissible which means it should not yet be categorised a prion disease under the current terminology.
19. Summing up, the Chair noted that it was clear that more information was required to fully characterise and fill knowledge gaps regarding this disease. It was important that its unique pathology be more widely recognised to enable future diagnosis and enable tissue collection during autopsy procedures. SEAC will keep a watching brief on emerging data which may characterise the disease further.

Third case of vCJD reported in the United States
Editorial Team (eurosurveillance.weekly@hpa.org.uk), Eurosurveillance editorial office
A clinical diagnosis of variant Creutzfeldt Jakob Disease (vCJD) was confirmed after brain biopsy investigations in a United States (US) resident and reported in November [1]. The patient is a young man who grew up in Saudi Arabia and lived in the US since late 2005. Before that he visited the US once in 1989 and several times after 2001. He has never visited any country in Europe or received a blood transfusion nor has he undergone any neurosurgical procedure. This vCJD case is the third in a US resident. The previous two patients both grew up in the United Kingdom (UK), and this is where they were believed to have been infected [2].
In Saudi Arabia, the first and only previous case of vCJD was reported in 2005. This was suspected to be related to consumption of meat contaminated with the prion agent which causes bovine spongiform encephalitis in cattle (BSE). The European Food Safety Authority (http://www.efsa.org) has not published a geographical BSE risk assessment for Saudi Arabia [3] and there have been no cases of BSE in cattle reported by Saudi Arabia to the World Organisation for Animal Health (http://www.oie.int). Although the UK is not the only potential beef exporter to have had a BSE epidemic, it remains plausible, subject to Saudi Arabia's import policy, that contaminated beef was inadvertently imported from the UK to Saudi Arabia in the period before 1996 (when the EU banned the export of UK beef and cattle).
Based on this patient's history, the occurrence of a previously reported case of vCJD in Saudi Arabia, and the expected length of the incubation period for food-related vCJD, the most likely source of infection is thought to be contaminated meat products the patient consumed as a child when living in Saudi Arabia. The patient has no known history of donating blood, and investigations have identified no risk of onwards transmission within the US.
Variant Creutzfeldt-Jakob disease was first identified in the United Kingdom in the mid-1990s. As of November 2006, worldwide there have been 200 vCJD cases: 164 patients in the United Kingdom, 21 in France, four in Ireland, three in the US (including the present case), two in the Netherlands and one each in Canada, Italy, Japan, Portugal, Saudi Arabia and Spain [4]. All patients, except 10 (including the present case) had lived either in the United Kingdom (170 cases) or in France (20 cases). Evidence so far indicates that the most probable source of infection in most cases was consumption of meat products contaminated with the prion agent causing BSE.

Experimental Challenge of Cattle with H-type and L-type Atypical BSE

Groschup1. 1Friedrich-Loeffler-Institut, Greifswald-Insel Riems, Germany, 2Health Canada, Bureau of Microbial Hazards, Health Products & Food Branch, Ottawa, Canada, 3Health Canada, Transmissible Spongiform Encephalopathy Secretariat, Ottawa, Canada
Background: After the detection of two novel BSE forms designated H-type and L-type atypical BSE the question of the pathogenesis and the agent distribution of these two types in cattle was fully open. From initial studies of the brain pathology, it was already known that the anatomical distribution of L-type BSE differs from that of the classical type where the obex region in the brainstem always displays the highest PrPSc concentrations. In contrast in L-type BSE cases, the thalamus and frontal cortex regions showed the highest levels of the pathological prion protein, while the obex region was only weakly involved.
Methods:We performed intracranial inoculations of cattle (five and six per group) using 10%brainstemhomogenates of the two German H- and L-type atypical BSE isolates. The animals were inoculated under narcosis and then kept in a free-ranging stable under appropriate biosafety conditions.At least one animal per group was killed and sectioned in the preclinical stage and the remaining animals were kept until they developed clinical symptoms. The animals were examined for behavioural changes every four weeks throughout the experiment following a protocol that had been established during earlier BSE pathogenesis studies with classical BSE.
Results and Discussion: All animals of both groups developed clinical symptoms and had to be euthanized within 16 months. The clinical picture differed from that of classical BSE, as the earliest signs of illness were loss of body weight and depression. However, the animals later developed hind limb ataxia and hyperesthesia predominantly and the head. Analysis of brain samples from these animals confirmed the BSE infection and the atypical Western blot profile was maintained in all animals. Samples from these animals are now being examined in order to be able to describe the pathogenesis and agent distribution for these novel BSE types. Conclusions: A pilot study using a commercially avaialble BSE rapid test ELISA revealed an essential restriction of PrPSc to the central nervous system for both atypical BSE forms. A much more detailed analysis for PrPSc and infectivity is still ongoing.

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Authors: T. Singeltary; Bacliff, TX/US
Title: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
Body: Background
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and feed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods
12 years independent research of available data
Results
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries.
I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

I look forward to further transmission studies, and a true ENHANCED BSE/atypical BSE surveillance program put forth testing all cattle for human and animal consumption for 5 years. a surveillance program that uses the most sensitive TSE testing, and has the personnel that knows how to use them, and can be trusted. I look forward to a stringent mad cow feed ban being put forth, and then strictly enforced. we need a forced, not voluntary feed ban, an enhanced feed ban at that, especially excluding blood. we need some sort of animal traceability. no more excuses about privacy. if somebody is putting out a product that is killing folks and or has the potential to kill you, then everybody needs to know who they are, and where that product came from. same with hospitals, i think medical incidents in all states should be recorded, and made public, when it comes to something like a potential accidental transmission exposure event. so if someone is out there looking at a place to go have surgery done, if you have several hospitals having these type 'accidental exposure events', than you can go some place else. it only makes sense. somewhere along the road, the consumer lost control, and just had to take whatever they were given, and then charged these astronomical prices. some where along the line the consumer just lost interest, especially on a long incubating disease such as mad cow disease i.e. Transmissible Spongiform Encephalopathy. like i said before, there is much more to the mad cow story than bovines and eating a hamburger, we must start focusing on all TSE in all species. ...TSS

CJD RISING SWITZERLAND
CJD is a predominantly sporadic disorder but can also occur as a dominantly inherited or infective condition. Only one of the 26 most recent confirmed cases was identified as carrying a disease related mutation of the PRNP gene, none had identifiable iatrogenic exposure, and none resembled variant CJD. Thus 25 of the 26 cases appear to be sporadic cases. Sporadic CJD is distributed worldwide with a reported incidence of about one in a million per year. Raised awareness of the disease in recent years could account for an increase in reported cases of CJD, although neither an increase in the average age of patients nor more frequent recognition of CJD amongst residents of nursing homes (where dementing illness is prevalent and misdiagnosis might be expected) were seen in the Swiss cases. Moreover, improved ascertainment as an explanation for the observed increase would imply levels of under-reporting in countries other than Switzerland, which appear implausible. The authors of the Lancet report suggest that the rise in cases might be due to some form of unidentified iatrogenic transmission or to exposure to a zoonotic source of infection, though cases do not resemble variant Creutzfeldt-Jakob disease (vCJD). The ongoing surveillance of CJD in Switzerland and the rest of Europe is essential to monitor the situation to see if this rise is sustained in Switzerland, and if a similar rise occurs in other countries (see http://www.eurocjd.ed.ac.uk).

Prion data suggest BSE link to sporadic CJD Declan Butler
Predicting the number of cases of Creutzfeldt–Jakob disease (CJD) in people as a result of transmission of bovine spongiform encephalopathy (BSE) has just got more difficult.Whereas it was thought that BSE only caused a new form of the disease called variant CJD (vCJD), a study in mice from a team led by John Collinge at University College London suggests that it may also cause a disease indistinguishable from the commonest form of classical, or 'sporadic', CJD (E.
http://www.nature.com/nature/journal/v420/n6915/full/420450a.html
IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;
However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).
IF we go further and look at some of the other documented BSE countries, you will the increase of sporadic CJD there as well ;
Canada from 2 to 25
France from 35 to 108
Germany 21+ to 96
Italy 27 to 76

Switzerland sporadic CJD ;
Swiss rise in CJD raises concerns over possible BSE link [LONDON] THE LANCET
Plaque attack: Swiss patients have spongiform patterns in the brain typical of sporadic CJD. The number of people dying from Creutzfeldt-Jakob disease (CJD) has risen sharply in Switzerland -- sparking fears of a possible link with bovine spongiform encephalopathy (BSE).
BSE is thought to be the cause of a distinctive form of the brain-wasting disease known as variant CJD. The Swiss cases, in contrast, are standard 'sporadic' CJD. Each year between 1997 and 2000, no more than 11 Swiss people developed CJD. But 19 cases were reported in 2001, and seven were recorded in the first quarter of this year. This is some four times higher than the incidence elsewhere, reports a team led by Adriano Aguzzi of the University Hospital Zurich (M. Glatzel et al. Lancet 360, 139-141; 2002).
The increase could be a mere statistical blip, or it may be due to increased awareness of the disease leading to more diagnoses. More disturbing is the possibility that the cases are linked to the consumption of BSE-infected meat products -- which would mean that the BSE agent can cause two distinct forms of CJD.
Possible links between the Swiss CJD cases and BSE will now be explored by strain-typing experiments in which the disease is transmitted to mice. These tests will take at least a year to complete. "It's the best way to establish or exclude any suspected link," says Moira Bruce of the UK Institute for Animal Health's Neuropathogenesis Unit in Edinburgh.
======================================
Experiences in England and Switzerland -- two countries that discovered mad cow disease in their cattle -- have heightened concerns about the possibility some cases of sporadic CJD are due to consuming mad-cow-tainted beef. Both countries have reported increases in sporadic CJD since mad cow was first detected in British herds in 1986.
Switzerland discovered last year its CJD rate was twice that of any other country in the world. Switzerland had been seeing about eight to 11 cases per year from 1997 to 2000. Then the incidence more than doubled, to 19 cases in 2001 and 18 cases in 2002.

Mouse model sheds new light on human prion disease

Professor John Collinge said We are not saying that all or even most cases of sporadic CJD are as a result of BSE exposure, but some more recent cases may be the incidence of sporadic CJD has shown an upward trend in the UK over the last decade. While most of this apparent increase may be because doctors are now more aware of CJD and better at diagnosing it, serious consideration should be given to a proportion of this rise being BSE-related. Switzerland, which has had a substantial BSE epidemic, has noted a sharp recent increase in sporadic CJD.

ITEM 8 – PUBLIC QUESTION AND ANSWER SESSION
40. The Chair explained that the purpose of the question and answer session was to give members of the public an opportunity to ask questions related to the work of SEAC. Mr Terry Singeltary (Texas, USA) had submitted a question prior to the meeting, asking: “With the Nor-98 now documented in five different states so far in the USA in 2007, and with the two atypical BSE H-base
13 © SEAC 2007
cases in Texas and Alabama, with both scrapie and chronic wasting disease (CWD) running rampant in the USA, is there any concern from SEAC with the rise of sporadic CJD in the USA from ''unknown phenotype'', and what concerns if any, in relations to blood donations, surgery, optical, and dental treatment, do you have with these unknown atypical phenotypes in both humans and animals in the USA?

103RD MEETING OF THE SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE
103RD MEETING OF THE SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE
The Spongiform Encephalopathy Advisory Committee held its 103rd Meeting in London on 24th November 2009, and discussed the following:
CURRENT ISSUES
SEAC was informed about:
• Confirmation of BSE in a Scottish goat originally diagnosed with scrapie in 1990; the goat culled in 1990 was born prior to the introduction of the ruminant feed ban and could have been exposed to contaminated feed.
• The first case of atypical scrapie discovered in a sheep from New Zealand.
• A recommendation to Health Ministers by the Advisory Committee on the Safety of Blood Tissues and Organs that prion filtration should be introduced for blood used to treat patients who were not exposed to BSE through their diet.
• Recently published research1 on the discovery in Papua New Guinea of a novel protective prion protein variant.
CJD UPDATE
SEAC was updated on the number of clinical cases of variant Creutzfeldt-Jakob Disease (vCJD) and sporadic CJD (sCJD). To date there have been 170 definite or probable UK cases of clinical vCJD. 167 of these are associated with probable dietary exposure to BSE and three arose after transfusions of blood from donors who later developed vCJD. The mean age of death was 30 years. There have been no cases of vCJD in individuals born after 1989.

Elsewhere in the world, 47 vCJD cases have been reported: 25 in France, five in Spain, four in the Republic of Ireland, three in both the USA and the Netherlands, two in Portugal and Italy and single cases in Canada, Saudi Arabia and Japan.
A brief report was provided on the novel human disease known as Protease-Sensitive Prionopathy (PSPr). Eleven cases have been reported with a mean age of onset of 62 years and disease duration of 20 months. The committee thought it was important that the unique pathology of this disease be more widely recognised to enable future diagnosis and tissue collection during autopsy procedures. SEAC will keep a watching brief on emerging data which may characterise this disease further.
EFFECT OF AGE ON THE PATHOGENESIS OF TSEs Most clinical cases of variant CJD have occurred in young adults, the median age at onset of disease being 26 years and the median age at death 28 years (the comparable ages for sporadic CJD are both 67). The reasons behind this apparent age-related susceptibility are uncertain. A recent paper2 reports the findings of a study in mice, which suggest that the age related decline in the functioning of follicular dendritic cells might impair TSE pathogenesis. The Committee agreed that a competent immune system was required for efficient replication of TSEs in the host. It was noted that older people are more immuno-compromised than the young, but there is very little data on the effect of ageing on the human immune system. The Committee concluded that there are insufficient data to suggest that this might provide an explanation for the young age of vCJD patients.
UP-DATE ON vCJD PREVALENCE STUDIES
The committee received an update on progress with the vCJD prevalence studies being conducted by the Health Protection Agency. This covered the National Anonymous Tonsil Archive (NATA), the post mortem archive and a new study of appendices. To date, NATA has tested approximately 80,000 pairs of tonsils and none were positive. A pilot for a study of spleens obtained

from post mortems, that will assess a number of potential methodologies, will start in early 2010, and report on the efficacy of these methodologies in June 2010. The new study of 30,000 appendices, to be tested by immunohistochemistry, will also start in early 2010. The Committee noted progress, and commented that in order to have sufficient power, the spleen study would have to test approximately 50,000 samples.
CATEGORY 3 ANIMAL PRODUCTS IN FERTILISERS
Building on previous work in 2005, Defra has commissioned a full risk assessment, which SEAC was invited to consider, to evaluate the amount of potential infectivity available in the soil of nonpasture land following the application of Category 3-derived3 fertiliser.
The committee considered that the methodology used in the risk assessment was scientifically valid, but felt that too many worst case assumptions had been made in addressing the paucity of experimental data, that certain temporal aspects could have been addressed differently and that the possibility of regulatory failure had not been sufficiently considered.
FUTURE OPERATION OF SEAC
The Committee discussed the future organisation of SEAC business and the desirability of streamlining the decision making process, so that Ministers could obtain advice more quickly. In particular, SEAC considered a proposal that in future much of its business could be dealt with by correspondence, rather than in face-to-face meetings.
In discussion the committee recognised that some SEAC business could be carried out more efficiently by e-mail correspondence. The process would need to be structured, perhaps at fixed times of the year and the discussion would be summarised and recorded on the SEAC Website so that the decision-making process was transparent and available for public scrutiny. However, it was important that the committee still aimed to meet in person twice or three times per year.

I have tried to get these papers through the court, but no luck. they want me to pay to retrieve the papers, and i am not going to pay for something I know happened. about like the last two FOIA on suspect mad cow feed going into commerce in the USA in 2009. I knew it had, but wanted them to say it. and they finally did via the FOIA.
Members of The HSUS are also concerned about the meat products provided to their children through the National School Lunch Program. More than 31 million school children receive lunches through the program each school day. To assist states in providing healthful, low-cost or free meals, USDA provides states with various commodities including ground beef. As evidenced by the HallmarkNVestland investigation and recall, the potential for downed animals to make their way into the National School Lunch Program is neither speculative nor hypothetical.

SaBTO Advisory Committee on the Safety of Blood, Tissues and Organs 2nd Public Meeting 27 October 2009
SaBTO
Advisory Committee on the Safety of Blood, Tissues and Organs
2nd Public Meeting
“Blood Donation – Selection, Deferral and Exclusion”
27 October 2009
Royal Horticultural Halls, London SW1P
At their inaugural meeting in January 2008, members of SaBTO decided that a public meeting should be held every year, focusing on a particular issue within the committee’s remit. The 2009 Public Meeting will focus on the issue of donor selection. Selection of donors is key to the delivery of a safe blood supply. Many prospective donors may be turned down for a variety of reasons, including age, sexual history and medical concerns. As a scientific advisory committee, SaBTO is concerned that exclusion or deferral of prospective blood donors is done for justifiable reasons and in the best interests of blood recipients.
The format of the afternoon will include an introduction to SaBTO and donor selection, and an open forum with the opportunity for the audience to comment and ask questions.
The committee hopes that the audience will reflect a wide range of stakeholders and interest groups. Should the event be oversubscribed, there will be a limit of one delegate per organisation. If you are interested in attending. please e-mail SaBTO@dh.gsi.gov.uk or telephone 020 7972 4750 by 13 October 2009 (this deadline has been extended). Please note that this event is free of charge for all delegates.
The Advisory Committee on the Safety of Blood, Tissues, and Organs (SaBTO) is a Non-Departmental Public Body, with an independent Chair and members selected by the Appointments Commission for their specific areas of expertise. SaBTO provides independent advice to the UK Government and the Devolved Administrations on the most appropriate ways to ensure the safety of blood, cells, tissues, and organs for transfusion/transplantation. SaBTO also provides advice on the microbiological safety of gametes and stem cells, and considers both risk assessment and risk management options for Ministers and UK Health Departments to consider.

SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE Minutes of the 99th meeting held on 14th December 2007
snip...
ITEM 8 – PUBLIC QUESTION AND ANSWER SESSION 40.
The Chair explained that the purpose of the question and answer session was to give members of the public an opportunity to ask questions related to the work of SEAC. Mr Terry Singeltary (Texas, USA) had submitted a question prior to the meeting, asking: “With the Nor-98 now documented in five different states so far in the USA in 2007, and with the two atypical BSE H-base cases in Texas and Alabama, with both scrapie and chronic 14 © SEAC 2007 wasting disease (CWD) running rampant in the USA, is there any concern from SEAC with the rise of sporadic CJD in the USA from ''unknown phenotype'', and what concerns if any, in relations to blood donations, surgery, optical, and dental treatment, do you have with these unknown atypical phenotypes in both humans and animals in the USA? Does it concern SEAC, or is it of no concern to SEAC? Should it concern USA animal and human health officials?” 41.
A member considered that this question appeared to be primarily related to possible links between animal and human TSEs in the USA.
There is no evidence that sCJD is increasing in the USA and no evidence of any direct link between TSEs and CJD in the USA. Current evidence does not suggest that CWD is a significant risk to human health. There are unpublished data from a case of human TSE in the USA that are suggestive of an apparently novel form of prion disease with distinct molecular characteristics. However, it is unclear whether the case had been further characterised, if it could be linked to animal TSEs or if other similar cases had been found in the USA or elsewhere. In relation to the possible public health implications of atypical scrapie, H-type BSE and CWD, research was being conducted to investigate possible links and surveillance was in place to detect any changes in human TSEs. Although possible links between these diseases and human TSEs are of concern and require research, there is no evidence to suggest immediate public health action is warranted. The possible human health risks from classical scrapie had been discussed earlier in the meeting. Members noted that there are effective channels of discussion and collaboration on research between USA and European groups. Members agreed it is important to keep a watching brief on new developments on TSEs.

10 people killed by new CJD-like disease A NEW form of fatal dementia has been discovered in 16 Americans, 10 of whom have already died of the condition. It resembles Creutzfeldt-Jakob disease - with patients gradually losing their ability to think, speak and move - but has features that make it distinct from known forms of CJD.
No one yet knows how the disease originates, or under what conditions it might spread. Nor is it clear how many people have the condition. "I believe the disease has been around for many years, unnoticed," says Pierluigi Gambetti, director of the US National Prion Disease Pathology Surveillance Center at Case Western Reserve University in Cleveland, Ohio. Cases may previously have been mistaken for other forms of dementia.
Since Gambetti's team wrote a paper describing an initial 11 cases referred to his centre between 2002 and 2006 (Annals of Neurology, vol 63, p 697), another five have come to light. "So it is possible that it could be just the tip of the iceberg," Gambetti says.

Communicated by: Terry S. Singeltary Sr. <:flounder9@verizon.net>
[In submitting these data, Terry S. Singeltary Sr. draws attention to the steady increase in the "type unknown" category, which, according to their definition, comprises cases in which vCJD could be excluded. The total of 26 cases for the current year (2007) is disturbing, possibly symptomatic of the circulation of novel agents. Characterization of these agents should be given a high priority. - Mod.CP]

There is a growing number of human CJD cases, and they were presented last week in San Francisco by Luigi Gambatti(?) from his CJD surveillance collection.
He estimates that it may be up to 14 or 15 persons which display selectively SPRPSC and practically no detected RPRPSC proteins.

2008
The statistical incidence of CJD cases in the United States has been revised to reflect that there is one case per 9000 in adults age 55 and older. Eighty-five percent of the cases are sporadic, meaning there is no known cause at present.

O.2.2
vCJD infection in an asymptomatic UK haemophilic patient
Alexander Peden1, Graham Fairfoul1, Suzanne Lowrie1, Linda McCardle1, Mark Head1, Seth Love2, Hester Ward1, Simon Cousens3, David Keeling4, Carolyn Millar5, FGH Hill6, James Ironside1 1University of Edinburgh, UK; 2Frenchay Hospital, Bristol, UK; 3London School of Hygiene and Tropical Medicine, UK; 4Churchill Hospital, Oxford, UK; 5Imperial College London, UK; 6Birmingham Children’s Hospital, Birmingham, UK
We describe a study of 17 UK patients with haemophilia considered to be at increased risk of vCJD through exposure to UK plasma products. 10 autopsy cases and 7 biopsy cases were analysed for disease- associated, protease-resistant prion protein (PrPres). The tissues available from each case were variable, ranging from a single biopsy sample to a wide range of autopsy tissues. A single specimen from the spleen of one autopsy case gave a strong positive result on repeated testing for PrPres by Western blot analysis. This tissue came from a 73 year-old male with no history of neurological disease, who was heterozygous (methionine/valine) at codon 129 in the prion protein gene. He had received over 9,000 units of Factor VIII concentrate prepared from plasma pools known to include donations from a vCJD-infected donor, and some 400,000 units not known to include donations from vCJD-infected donors. He had also received 14 units of red blood cells and had undergone several surgical and invasive endoscopic procedures. Estimates of the relative risks of exposure though diet, surgery, endoscopy, blood transfusion and receipt of UK plasma products suggest that by far the most likely route of infection was receipt of UK plasma products.
O.2.3
Detection of prion particles in body fluids of humans and animals
Detlev Riesner Institut fur Physikalische Biologie, Heinrich-Heine- Universitat Dusseldorf, Germany
A major structural difference between the cellular isoform of the prion protein PrPC and the pathogenic isoform PrPSc is the much higher state of molecular aggregation of PrPSc. PK-resistance as normally used for PrPSc-characterization is not reliably valid for all species, strains and sources of prions. The method of suface-FIDA (fluorescence-intensity distribution analysis) was developed avoiding PK-digestion and detecting specifically disease related PrP-aggregates (Birkmann et al 2007, J. Vet. Microbiol 123, 294-304). After partial purification PrP-aggregates are bound to a chip covered with the captureantibody SAF32, labeled with two types of antibodies against two different epitopes and carrying two different fluorescent dyes. A dual-color laser beam is scanning the chip surface, and the fluorescence signals are evaluated in respect to local coincidence, intensities and particle size. The method was applied to brain homogenate of sCJD-victims (post mortem), to CSF-samples of BSE-afflicted cattle (ante mortem) and blood plasma of scrapie sheep (ante mortem). Particles of PrP-aggregates could be detected in all samples, exhibiting a diameter range of 300 nm (optical resolution) to 1ƒÊm. PrP-aggregates were detected with 100% sensitivity in the sCJD-brain homogenate samples; studies on CSF are ongoing. PrP-aggregates were detected in CSF of BSE-cattle, but the number of samples was too little to evaluate the sensitivity. Only one antibody was available to detect scrapie-PrP-aggregates from blood plasma; the sensitivity of 60% will be improved in the ongoing experiments with a second antibody. PrP-aggregates can be used as seeds for fibril formation with recombinant PrP as template (Stohr et al., 2008, PNAS 105, 2409-14). This system will be used as amplification of the particle detection method.
O.2.4
Detection of prions in blood leucocytes
Linda A. Terry, Laurence Howells, Jeremy Hawthorn, Sally Everest, Sarah Jo Moore, Jane C. Edwards Veterinary Laboratories Agency, UK
Background: Infected human blood has been implicated in the iatrogenic transmission of vCJD in four reported cases. Experimental transmission studies have demonstrated that blood from scrapie and BSE infected sheep also contains infectivity. Rodent models of prion disease implicated both cellular and plasma fractions. However, direct detection of PrPsc from blood in the absence of in vitro amplification or bioassay has proved difficult. Methods for the direct detection of PrPsc in blood would be advantageous for the study of the pathogenesis of TSEs and as a basis for a blood test. Objectives: To develop a method for the direct detection of PrPsc in blood cells from scrapie and BSE infected sheep; to study the temporal distribution of PrPsc in blood and to determine the identity of the cells bearing prions in blood. Methods: Peripheral blood mononuclear cells (PBMC) were isolated from sheep naturally infected with scrapie or experimentally infected with BSE at the clinical stage of disease and from scrapie infected sheep from 3 months of age through to clinical end-point. PBMCs were tested for PrPsc content by a direct immunoassay based on the IDEXX CWD HerdChek kit. Different subsets of PBMCs were isolated by subset specific cell surface markers and magnetic bead separation and analysed for PrPsc content. Results: PrPSc was detected in 54% of sheep with clinical scrapie and 71% of sheep with clinical BSE. A longitudinal study of the temporal distribution of blood PBMC associated PrPsc showed that the detection rate increases during the course of disease and is more likely to be observed during the second half of the incubation period. Additionally detection is more likely in scrapie infected sheep if they carry the PRNP genotype of VRQ/VRQ. Cell separation studies showed that the PrPsc is associated with a specific cell subset implicating a subset of B lymphocytes. Discussion. This is the first report of the direct detection of PrPsc in cells isolated from sheep blood in the absence of in vitro amplification or bioassay. Since PrPsc can be detected from as early as 3 months of age in sheep naturally infected with scrapie, correlating with initial replication in the gut-associated lymphoid tissue, the assay could be the basis of a preclinical test. The identification of the cell subset carrying PrPsc progresses our understanding of the pathogenesis of the disease. However, it remains unclear whether this cell subset is responsible for the dissemination of prions or in clearance of circulating PrPsc. Funded by defra, UK and IDEXX.

Human urine and PrP
Silvio Notari1*, Liuting Qing1*, Ayuna Dagdanova1*, Sergei Ilchenko1, Mark E. Obrenovich1, Wen-Quan Zou1, Maurizio Pocchiari2, Pierluigi Gambetti1, Qingzhong Kong1, Shu G. Chen1 1Case Western Reserve University, USA; 2Istituto Superiore di Sanità, Italy
Background: The presence and the characteristics of prion protein (PrP) in human urine under normal conditions are controversial. Similarly, there are no definite data on the presence of infectivity in urine in the course of naturally occurring human prion diseases. Objectives: 1) To definitely determine the presence and characteristics of PrPC in normal urine. 2) To evaluate the prion infectivity in human urine in sporadic Creutzfeldt-Jakob disease (sCJD), we have carried out a set of bioassays in humanized transgenic mouse with urine samples collected from sCJD subjects. Methods: 1) Advanced mass spectrometry and experimental treatments have been used to demonstrate the presence, primary structure and posttranslational modifications of purified urinary PrPC (uPrP). 2) Bioassays were performed by intracerebral inoculation of 100 times concentrated and dialyzed urine, collected from three sCJD-MM1 cases to humanized transgenic mice and from appropriate controls. Results: We found that human urine contains significant amount of PrP (approximately 10 ng/ml) that is truncated with the major N-terminus at residue 112 as the PrPC fragment identified as C1, and it carries an anchor, which is soluble because likely lacks the phosholipid component. None of the humanized transgenic mice inoculated with sCJD concentrated urine had evidence of prion disease during a period of over 700 days (their normal life expectancy) leading to the conclusion that prion infectivity in sCJD urine, if present, must be less than 6 infectious units/100ml. Discussion: The issues raised in the discussion will include: 1) The origin of the truncated uPrP; 2) How the present data compare with the experimental studies published to date that indicate presence of infectivity; 3) The practical implications of our findings. *

All separated components, prepared from BSE-infected sheep blood, are infectious upon transfusion
Sandra McCutcheon1, Anthony Richard Alejo Blanco1, Christopher de Wolf1, Boon Chin Tan1, Nora Hunter1, Valerie Hornsey2, Christopher Prowse2, Marc Turner2, Martin H Groschup3, Dietmar Becher4, Fiona Houston5, Jean C Manson1 1The Roslin Institute and R (D) SVS, University of Edinburgh, UK; 2Scottish National Blood Transfusion Service, UK; 3FLIFederal Research Institute for Animal Health, Germany; 4Micromun, Germany; 5University of Glasgow, UK
Background: The possibility that vCJD may be transmitted by blood transfusion is serious public health issue, of which 4 probable (3 clinical) cases have been attributed. Recently a case of asymptomatic vCJD infection was identified in a haemophiliac; following treatment with clotting factors from UK plasma pools. Sheep orally infected with BSE provide a suitable model, to assess vCJD infection in humans & risk reduction methods, as the distribution of PrPSc & infectivity in lymphoid tissues resembles that of vCJD patients.
Objectives: To determine qualitative and quantitative data on the changes in infectivity in blood and its clinically relevant components with time, to assess the effect of leucodepletion of such products and the potential for secondary transmission by blood transfusion.
Methods: We orally infected sheep with bovine BSE brain homogenate and collected two full-sized donations of whole blood, before the onset of clinical signs. The following components were transfused into naive recipients: whole blood, buffy coat and leucoreduced and non leucoreduced plasma, platelets and red cells. A sub sample of all components was inoculated into TgShpXI mice for determination of infectivity titers. A unit of whole blood from selected primary recipients was transfused into secondary recipients. We are creating a blood archive throughout this study.
Results: 33% of the infected donors have been confirmed as having BSE. We have 4 transmissions of BSE-infectivity following the transfusion of whole blood, buffy coat and plasma. Short incubation times were recorded in these recipients (468, 513, 567 and 594 days) & were similar to those seen in their respective donors (534, 628, 614 and 614 days). The donor of buffy coat also donated both leucodepleted and non leucodepleted blood components to other recipients.
Discussion: Our study will provide invaluable data on the safety of blood products, in relation to TSE infection, used in human medicine (DoH 007/0162)
O.8.1
Variant CJD and plasma products
Robert G. Will National CJD Surveillance Unit, Edinburgh, UK
Evidence from the Transfusion Medicine Epidemiology Review (TMER) project indicates that variant CJD is transmissible through transfusion of labile blood components. The question as to whether plasma products sourced from vCJD contaminated plasma pools has been addressed by a number of risk assessments, with conflicting conclusions. Recently a case of possible vCJD infection in an individual with haemophilia has been described and analysis has suggested that infection may have been related to prior treatment with vCJD implicated Factor VIII. The details of this case will be described together with an analysis of plasma product exposures in UK clinical cases of vCJD.
O.8.2
Blood safety: from screening tests to prion removal
Marc Turner Scottish National Blood Transfusion Service and Department of Haematology, Royal Infirmary, Edinburgh, UK
Although the number of clinical cases of variant CJD continues to fall, concern remains within UK and Western European Blood Services in relation to the risk of transmission of variant CJD due to the estimated prevalence of sub-clinical infection in the general population and the clinical cases of transmission of variant CJD prions by blood components and plasma products. The UK Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) has considered a number of further precautionary measures including reducing exposure to blood transfusion, importation of blood components, implementation of prion assays and prion reduction for red cell concentrates. The latter two technologies are currently under independent evaluation and it is expected that contingent on the outcome of these an initial decision on whether or not to recommend implementation of these technologies will be made by SaBTO in Autumn 2009.
O.9.3
Updated risk assessment of variant Creutzfeldt-Jakob disease (vCJD) risks for recipients of plasma-derived blood clotting products in the U.S.
Hong Yang, Richard Forshee, Mark Walderhaug, Steven Anderson US Food and Drug Administration, USA
Background: A recent announcement by UK health authorities of a case of vCJD infection in a >70 year old person with hemophilia has prompted the US Food & Drug Administration (FDA) to re-evaluate vCJD risks in the U.S. via plasma-derived Factor VIII (pdFVIII) and to update its 2006 risk assessment. As of May 2009, confirmed vCJD deaths have occurred in persons who are homozygous methionine (MM) at codon 129 of the PRP gene. Several reports in the last few years have indicated signs of vCJD infection in persons of methionine-valine (MV) and homozygous valine (VV) genotypes. FDA updated risk assessment by assuming all genotypes are susceptible to vCJD and modeling the incubation periods for all three genotypes.
Objectives: To evaluate the vCJD risk for pdFVIII recipients with severe hemophilia and vonWillebrand diseases.
Methods: The model assumed equal susceptibility of three genotypes, a median incubation period of 12 years for the MM and 32 years for MV and VV genotypes, and vCJD infectivity was present in the blood of infected donors during the last 50% to 90% of incubation period. Model used statistical distributions for inputs including susceptibility to the disease, donation rates, frequency and duration of travel to the UK, France and other countries in Europe since 1980, the effectiveness of donor deferral policies and infectivity clearance during manufacturing processes.
Results: For severe hemophilia patients at the highest risk (prophylaxis, with inhibitor, with immune tolerance) the model estimated annual mean exposure to be ~7 x 10-8 iv ID50 or ~1 in 270,000 with the lower prevalence (4 per million) assumption, and ~1 x 10-4 iv ID50 or ~1 in 12,000 with the higher prevalence (1 per 4,225) assumption. Donor deferral policies reduce the risk by >92%.
Discussion: Due to limited data and knowledge of vCJD, the model estimates are uncertain. However, it suggests the risk is small, and donor deferral and manufacturing processes greatly reduce the risk.
P.10.7
Serial passage of sCJD in humanised transgenic mice indicates two major transmission strains associated with PrPSc of either type 1 or 2
Matthew Bishop, Robert Will, Enrico Cancellotti, Jean Manson University of Edinburgh, UK
Background: Questions remain about the aetiology of sporadic CJD and whether phenotypic variation is solely controlled by factors such as codon 129 genotype and biochemistry of PrPC. Variation in infective strain has not been clearly demonstrated in sCJD.
Objectives: By serial passage of sCJD in transgenic mice expressing human prion protein with MM, MV, and VV codon 129 genotypes we aimed to understand strain transmission characteristics for the three most commonly observed phenotypes of sCJD.
Methods: We performed intracerebral inoculation of humanised transgenic mice with brain homogenates derived from similar mice previously inoculated with frontal cortex from sCJD patients of subgroups MM1, MV2, and VV2. These mice were assessed for clinical TSE signs, for TSE vacuolation, and deposition of PrPSc.
Results: sCJD(MM1) passage via all mice showed transmission profiles similar to primary inoculation. sCJD(MV2) passage via HuMM and HuVV mice showed a transmission profile similar to primary inoculation. Passage via a HuMV mouse showed transmission properties similar to not only the primary inoculum but also sCJD(MM1). sCJD(VV2) passage via HuMV and HuVV mice showed transmission profiles similar to the primary inoculation. Passage via a HuMM mouse showed transmission properties similar to not only the sCJD(VV2) primary inoculum but also sCJD(MM1). Cluster analysis of the lesion profile data showed that three clusters seen after primary inoculation were reduced to two following second passage, identified by the biochemical type of PrPSc (1 or 2) found in the host mice.
Discussion: Serial passage of sCJD subgroups MM1, MV2, and VV2 shows that PrPSc type and mouse codon 129 genotype determine the secondary transmission profile, independently of the originating inoculum strain. There are associations between type 1 PrPSc and C129-Met, and type 2 PrPSc and C129-Val. This should allow us to investigate further the relationship between PrPSc, genotype, infection, and pathology.

Detection of cellular prion protein (PrPc) in plasma from healthy cynomolgus monkeys (Macaca fascicularis) and changes observed after BSE infection
Barbara Yutzy, Edgar Holznagel, Johannes Löwer Paul-Ehrlich-Institut, Germany
Background: Orally BSE-dosed cynomolgus monkeys represent a valuable model to examine the kinetic of blood infectivity and to assess the risk of blood-borne transmission of variant Creutzfeldt-Jacob disease (vCJD).
Methods: Blood samples were collected monthly from BSE-infected (n = 18) and non-infected female cynomolgus monkeys (n = 8) over a period of up to 9 years. PrPc concentrations were retrospectively analyzed in plasma samples by a dot blot assay and by a sandwich ELISA using a highly sensitive dissociation- enhanced lanthanide fluoro-immunoassay (DELFIA) for detection. Different blood preparation protocols were evaluated to obtain plasma.
Objective: To detect changes in the levels of soluble plasmaderived PrPc. Results: Different blood preparation protocols had a significant effect on the measured plasma PrPc concentrations. In non-infected macaques, concentrations of soluble, plasmaderived PrPc were at least 10-fold lower compared to plasma concentrations in healthy humans. Levels of plasma PrPc increased 6 – 12 months after experimental BSE infection, remained high during the asymptomatic phase, and dropped towards the clinical phase. Soluble, plasma-derived PrPc molecules were PK-sensitive in BSE-infected macaques.
Discussion: There is a species-specific difference in the PrPc concentrations between human and macaque. At least a part of the plasma-derived PrPc fraction originates from blood cells. Andfinally, BSE infection caused an increase in plasma PrPc levels during the asymptomatic phase of infection. Blood transfusion studies have been initiated to examine whether these PK-sensitive PrP molecules carry infectivity.

Office of Inspector General Semiannual Report to Congress FY 2007 - 2nd Half
Two Texas Companies Sentenced and Fined for Misbranding Meat Products In April 2007, two closely held and related Texas companies pled guilty in Federal court and were sentenced to 12 months of probation and ordered to pay $10,250 in fines for misbranding meat products. One of the companies sold adulterated meat products to a retail store in New Mexico. Additionally, portions of the invoices failed to properly and consistently identify the meat products as being from cattle more than 30 months old at time of slaughter. This information is required to be disclosed because of bovine spongiform encephalopathy (BSE, or "mad cow disease") concerns. No adulterated meat reached consumers.

Advisory Committee on the Safety of Blood, Tissues and Organs
2nd Public Meeting
“Blood Donation – Selection, Deferral and Exclusion”
27 October 2009
Royal Horticultural Halls, London SW1P
At their inaugural meeting in January 2008, members of SaBTO decided that a public meeting should be held every year, focusing on a particular issue within the committee’s remit. The 2009 Public Meeting will focus on the issue of donor selection. Selection of donors is key to the delivery of a safe blood supply. Many prospective donors may be turned down for a variety of reasons, including age, sexual history and medical concerns. As a scientific advisory committee, SaBTO is concerned that exclusion or deferral of prospective blood donors is done for justifiable reasons and in the best interests of blood recipients.
The format of the afternoon will include an introduction to SaBTO and donor selection, and an open forum with the opportunity for the audience to comment and ask questions.
The committee hopes that the audience will reflect a wide range of stakeholders and interest groups. Should the event be oversubscribed, there will be a limit of one delegate per organisation. If you are interested in attending. please e-mail SaBTO@dh.gsi.gov.uk or telephone 020 7972 4750 by 13 October 2009 (this deadline has been extended). Please note that this event is free of charge for all delegates.
The Advisory Committee on the Safety of Blood, Tissues, and Organs (SaBTO) is a Non-Departmental Public Body, with an independent Chair and members selected by the Appointments Commission for their specific areas of expertise. SaBTO provides independent advice to the UK Government and the Devolved Administrations on the most appropriate ways to ensure the safety of blood, cells, tissues, and organs for transfusion/transplantation. SaBTO also provides advice on the microbiological safety of gametes and stem cells, and considers both risk assessment and risk management options for Ministers and UK Health Departments to consider.

SPONGIFORM ENCEPHALOPATHY ADVISORY COMMITTEE Minutes of the 99th meeting held on 14th December 2007
snip...
ITEM 8 – PUBLIC QUESTION AND ANSWER SESSION 40.
The Chair explained that the purpose of the question and answer session was to give members of the public an opportunity to ask questions related to the work of SEAC. Mr Terry Singeltary (Texas, USA) had submitted a question prior to the meeting, asking: “With the Nor-98 now documented in five different states so far in the USA in 2007, and with the two atypical BSE H-base cases in Texas and Alabama, with both scrapie and chronic 14 © SEAC 2007 wasting disease (CWD) running rampant in the USA, is there any concern from SEAC with the rise of sporadic CJD in the USA from ''unknown phenotype'', and what concerns if any, in relations to blood donations, surgery, optical, and dental treatment, do you have with these unknown atypical phenotypes in both humans and animals in the USA? Does it concern SEAC, or is it of no concern to SEAC? Should it concern USA animal and human health officials?” 41.
A member considered that this question appeared to be primarily related to possible links between animal and human TSEs in the USA.
There is no evidence that sCJD is increasing in the USA and no evidence of any direct link between TSEs and CJD in the USA. Current evidence does not suggest that CWD is a significant risk to human health. There are unpublished data from a case of human TSE in the USA that are suggestive of an apparently novel form of prion disease with distinct molecular characteristics. However, it is unclear whether the case had been further characterised, if it could be linked to animal TSEs or if other similar cases had been found in the USA or elsewhere. In relation to the possible public health implications of atypical scrapie, H-type BSE and CWD, research was being conducted to investigate possible links and surveillance was in place to detect any changes in human TSEs. Although possible links between these diseases and human TSEs are of concern and require research, there is no evidence to suggest immediate public health action is warranted. The possible human health risks from classical scrapie had been discussed earlier in the meeting. Members noted that there are effective channels of discussion and collaboration on research between USA and European groups. Members agreed it is important to keep a watching brief on new developments on TSEs.

10 people killed by new CJD-like disease A NEW form of fatal dementia has been discovered in 16 Americans, 10 of whom have already died of the condition. It resembles Creutzfeldt-Jakob disease - with patients gradually losing their ability to think, speak and move - but has features that make it distinct from known forms of CJD.
No one yet knows how the disease originates, or under what conditions it might spread. Nor is it clear how many people have the condition. "I believe the disease has been around for many years, unnoticed," says Pierluigi Gambetti, director of the US National Prion Disease Pathology Surveillance Center at Case Western Reserve University in Cleveland, Ohio. Cases may previously have been mistaken for other forms of dementia.
Since Gambetti's team wrote a paper describing an initial 11 cases referred to his centre between 2002 and 2006 (Annals of Neurology, vol 63, p 697), another five have come to light. "So it is possible that it could be just the tip of the iceberg," Gambetti says.

Communicated by: Terry S. Singeltary Sr. <:flounder9@verizon.net>
[In submitting these data, Terry S. Singeltary Sr. draws attention to the steady increase in the "type unknown" category, which, according to their definition, comprises cases in which vCJD could be excluded. The total of 26 cases for the current year (2007) is disturbing, possibly symptomatic of the circulation of novel agents. Characterization of these agents should be given a high priority. - Mod.CP]

There is a growing number of human CJD cases, and they were presented last week in San Francisco by Luigi Gambatti(?) from his CJD surveillance collection.
He estimates that it may be up to 14 or 15 persons which display selectively SPRPSC and practically no detected RPRPSC proteins.

2008
The statistical incidence of CJD cases in the United States has been revised to reflect that there is one case per 9000 in adults age 55 and older. Eighty-five percent of the cases are sporadic, meaning there is no known cause at present.

Creutzfeldt-Jakob Disease Surveillance Texas Data for Reporting Years 2000-2008

O.2.2
vCJD infection in an asymptomatic UK haemophilic patient
Alexander Peden1, Graham Fairfoul1, Suzanne Lowrie1, Linda McCardle1, Mark Head1, Seth Love2, Hester Ward1, Simon Cousens3, David Keeling4, Carolyn Millar5, FGH Hill6, James Ironside1 1University of Edinburgh, UK; 2Frenchay Hospital, Bristol, UK; 3London School of Hygiene and Tropical Medicine, UK; 4Churchill Hospital, Oxford, UK; 5Imperial College London, UK; 6Birmingham Children’s Hospital, Birmingham, UK
We describe a study of 17 UK patients with haemophilia considered to be at increased risk of vCJD through exposure to UK plasma products. 10 autopsy cases and 7 biopsy cases were analysed for disease- associated, protease-resistant prion protein (PrPres). The tissues available from each case were variable, ranging from a single biopsy sample to a wide range of autopsy tissues. A single specimen from the spleen of one autopsy case gave a strong positive result on repeated testing for PrPres by Western blot analysis. This tissue came from a 73 year-old male with no history of neurological disease, who was heterozygous (methionine/valine) at codon 129 in the prion protein gene. He had received over 9,000 units of Factor VIII concentrate prepared from plasma pools known to include donations from a vCJD-infected donor, and some 400,000 units not known to include donations from vCJD-infected donors. He had also received 14 units of red blood cells and had undergone several surgical and invasive endoscopic procedures. Estimates of the relative risks of exposure though diet, surgery, endoscopy, blood transfusion and receipt of UK plasma products suggest that by far the most likely route of infection was receipt of UK plasma products.
O.2.3
Detection of prion particles in body fluids of humans and animals
Detlev Riesner Institut fur Physikalische Biologie, Heinrich-Heine- Universitat Dusseldorf, Germany
A major structural difference between the cellular isoform of the prion protein PrPC and the pathogenic isoform PrPSc is the much higher state of molecular aggregation of PrPSc. PK-resistance as normally used for PrPSc-characterization is not reliably valid for all species, strains and sources of prions. The method of suface-FIDA (fluorescence-intensity distribution analysis) was developed avoiding PK-digestion and detecting specifically disease related PrP-aggregates (Birkmann et al 2007, J. Vet. Microbiol 123, 294-304). After partial purification PrP-aggregates are bound to a chip covered with the captureantibody SAF32, labeled with two types of antibodies against two different epitopes and carrying two different fluorescent dyes. A dual-color laser beam is scanning the chip surface, and the fluorescence signals are evaluated in respect to local coincidence, intensities and particle size. The method was applied to brain homogenate of sCJD-victims (post mortem), to CSF-samples of BSE-afflicted cattle (ante mortem) and blood plasma of scrapie sheep (ante mortem). Particles of PrP-aggregates could be detected in all samples, exhibiting a diameter range of 300 nm (optical resolution) to 1ƒÊm. PrP-aggregates were detected with 100% sensitivity in the sCJD-brain homogenate samples; studies on CSF are ongoing. PrP-aggregates were detected in CSF of BSE-cattle, but the number of samples was too little to evaluate the sensitivity. Only one antibody was available to detect scrapie-PrP-aggregates from blood plasma; the sensitivity of 60% will be improved in the ongoing experiments with a second antibody. PrP-aggregates can be used as seeds for fibril formation with recombinant PrP as template (Stohr et al., 2008, PNAS 105, 2409-14). This system will be used as amplification of the particle detection method.
O.2.4
Detection of prions in blood leucocytes
Linda A. Terry, Laurence Howells, Jeremy Hawthorn, Sally Everest, Sarah Jo Moore, Jane C. Edwards Veterinary Laboratories Agency, UK
Background: Infected human blood has been implicated in the iatrogenic transmission of vCJD in four reported cases. Experimental transmission studies have demonstrated that blood from scrapie and BSE infected sheep also contains infectivity. Rodent models of prion disease implicated both cellular and plasma fractions. However, direct detection of PrPsc from blood in the absence of in vitro amplification or bioassay has proved difficult. Methods for the direct detection of PrPsc in blood would be advantageous for the study of the pathogenesis of TSEs and as a basis for a blood test. Objectives: To develop a method for the direct detection of PrPsc in blood cells from scrapie and BSE infected sheep; to study the temporal distribution of PrPsc in blood and to determine the identity of the cells bearing prions in blood. Methods: Peripheral blood mononuclear cells (PBMC) were isolated from sheep naturally infected with scrapie or experimentally infected with BSE at the clinical stage of disease and from scrapie infected sheep from 3 months of age through to clinical end-point. PBMCs were tested for PrPsc content by a direct immunoassay based on the IDEXX CWD HerdChek kit. Different subsets of PBMCs were isolated by subset specific cell surface markers and magnetic bead separation and analysed for PrPsc content. Results: PrPSc was detected in 54% of sheep with clinical scrapie and 71% of sheep with clinical BSE. A longitudinal study of the temporal distribution of blood PBMC associated PrPsc showed that the detection rate increases during the course of disease and is more likely to be observed during the second half of the incubation period. Additionally detection is more likely in scrapie infected sheep if they carry the PRNP genotype of VRQ/VRQ. Cell separation studies showed that the PrPsc is associated with a specific cell subset implicating a subset of B lymphocytes. Discussion. This is the first report of the direct detection of PrPsc in cells isolated from sheep blood in the absence of in vitro amplification or bioassay. Since PrPsc can be detected from as early as 3 months of age in sheep naturally infected with scrapie, correlating with initial replication in the gut-associated lymphoid tissue, the assay could be the basis of a preclinical test. The identification of the cell subset carrying PrPsc progresses our understanding of the pathogenesis of the disease. However, it remains unclear whether this cell subset is responsible for the dissemination of prions or in clearance of circulating PrPsc. Funded by defra, UK and IDEXX.
O.2.6
Human urine and PrP
Silvio Notari1*, Liuting Qing1*, Ayuna Dagdanova1*, Sergei Ilchenko1, Mark E. Obrenovich1, Wen-Quan Zou1, Maurizio Pocchiari2, Pierluigi Gambetti1, Qingzhong Kong1, Shu G. Chen1 1Case Western Reserve University, USA; 2Istituto Superiore di Sanità, Italy
Background: The presence and the characteristics of prion protein (PrP) in human urine under normal conditions are controversial. Similarly, there are no definite data on the presence of infectivity in urine in the course of naturally occurring human prion diseases. Objectives: 1) To definitely determine the presence and characteristics of PrPC in normal urine. 2) To evaluate the prion infectivity in human urine in sporadic Creutzfeldt-Jakob disease (sCJD), we have carried out a set of bioassays in humanized transgenic mouse with urine samples collected from sCJD subjects. Methods: 1) Advanced mass spectrometry and experimental treatments have been used to demonstrate the presence, primary structure and posttranslational modifications of purified urinary PrPC (uPrP). 2) Bioassays were performed by intracerebral inoculation of 100 times concentrated and dialyzed urine, collected from three sCJD-MM1 cases to humanized transgenic mice and from appropriate controls. Results: We found that human urine contains significant amount of PrP (approximately 10 ng/ml) that is truncated with the major N-terminus at residue 112 as the PrPC fragment identified as C1, and it carries an anchor, which is soluble because likely lacks the phosholipid component. None of the humanized transgenic mice inoculated with sCJD concentrated urine had evidence of prion disease during a period of over 700 days (their normal life expectancy) leading to the conclusion that prion infectivity in sCJD urine, if present, must be less than 6 infectious units/100ml. Discussion: The issues raised in the discussion will include: 1) The origin of the truncated uPrP; 2) How the present data compare with the experimental studies published to date that indicate presence of infectivity; 3) The practical implications of our findings. *

All separated components, prepared from BSE-infected sheep blood, are infectious upon transfusion
Sandra McCutcheon1, Anthony Richard Alejo Blanco1, Christopher de Wolf1, Boon Chin Tan1, Nora Hunter1, Valerie Hornsey2, Christopher Prowse2, Marc Turner2, Martin H Groschup3, Dietmar Becher4, Fiona Houston5, Jean C Manson1 1The Roslin Institute and R (D) SVS, University of Edinburgh, UK; 2Scottish National Blood Transfusion Service, UK; 3FLIFederal Research Institute for Animal Health, Germany; 4Micromun, Germany; 5University of Glasgow, UK
Background: The possibility that vCJD may be transmitted by blood transfusion is serious public health issue, of which 4 probable (3 clinical) cases have been attributed. Recently a case of asymptomatic vCJD infection was identified in a haemophiliac; following treatment with clotting factors from UK plasma pools. Sheep orally infected with BSE provide a suitable model, to assess vCJD infection in humans & risk reduction methods, as the distribution of PrPSc & infectivity in lymphoid tissues resembles that of vCJD patients.
Objectives: To determine qualitative and quantitative data on the changes in infectivity in blood and its clinically relevant components with time, to assess the effect of leucodepletion of such products and the potential for secondary transmission by blood transfusion.
Methods: We orally infected sheep with bovine BSE brain homogenate and collected two full-sized donations of whole blood, before the onset of clinical signs. The following components were transfused into naive recipients: whole blood, buffy coat and leucoreduced and non leucoreduced plasma, platelets and red cells. A sub sample of all components was inoculated into TgShpXI mice for determination of infectivity titers. A unit of whole blood from selected primary recipients was transfused into secondary recipients. We are creating a blood archive throughout this study.
Results: 33% of the infected donors have been confirmed as having BSE. We have 4 transmissions of BSE-infectivity following the transfusion of whole blood, buffy coat and plasma. Short incubation times were recorded in these recipients (468, 513, 567 and 594 days) & were similar to those seen in their respective donors (534, 628, 614 and 614 days). The donor of buffy coat also donated both leucodepleted and non leucodepleted blood components to other recipients.
Discussion: Our study will provide invaluable data on the safety of blood products, in relation to TSE infection, used in human medicine (DoH 007/0162)
O.8.1
Variant CJD and plasma products
Robert G. Will National CJD Surveillance Unit, Edinburgh, UK
Evidence from the Transfusion Medicine Epidemiology Review (TMER) project indicates that variant CJD is transmissible through transfusion of labile blood components. The question as to whether plasma products sourced from vCJD contaminated plasma pools has been addressed by a number of risk assessments, with conflicting conclusions. Recently a case of possible vCJD infection in an individual with haemophilia has been described and analysis has suggested that infection may have been related to prior treatment with vCJD implicated Factor VIII. The details of this case will be described together with an analysis of plasma product exposures in UK clinical cases of vCJD.
O.8.2
Blood safety: from screening tests to prion removal
Marc Turner Scottish National Blood Transfusion Service and Department of Haematology, Royal Infirmary, Edinburgh, UK
Although the number of clinical cases of variant CJD continues to fall, concern remains within UK and Western European Blood Services in relation to the risk of transmission of variant CJD due to the estimated prevalence of sub-clinical infection in the general population and the clinical cases of transmission of variant CJD prions by blood components and plasma products. The UK Advisory Committee on the Safety of Blood, Tissues and Organs (SaBTO) has considered a number of further precautionary measures including reducing exposure to blood transfusion, importation of blood components, implementation of prion assays and prion reduction for red cell concentrates. The latter two technologies are currently under independent evaluation and it is expected that contingent on the outcome of these an initial decision on whether or not to recommend implementation of these technologies will be made by SaBTO in Autumn 2009.
O.9.3
Updated risk assessment of variant Creutzfeldt-Jakob disease (vCJD) risks for recipients of plasma-derived blood clotting products in the U.S.
Hong Yang, Richard Forshee, Mark Walderhaug, Steven Anderson US Food and Drug Administration, USA
Background: A recent announcement by UK health authorities of a case of vCJD infection in a >70 year old person with hemophilia has prompted the US Food & Drug Administration (FDA) to re-evaluate vCJD risks in the U.S. via plasma-derived Factor VIII (pdFVIII) and to update its 2006 risk assessment. As of May 2009, confirmed vCJD deaths have occurred in persons who are homozygous methionine (MM) at codon 129 of the PRP gene. Several reports in the last few years have indicated signs of vCJD infection in persons of methionine-valine (MV) and homozygous valine (VV) genotypes. FDA updated risk assessment by assuming all genotypes are susceptible to vCJD and modeling the incubation periods for all three genotypes.
Objectives: To evaluate the vCJD risk for pdFVIII recipients with severe hemophilia and vonWillebrand diseases.
Methods: The model assumed equal susceptibility of three genotypes, a median incubation period of 12 years for the MM and 32 years for MV and VV genotypes, and vCJD infectivity was present in the blood of infected donors during the last 50% to 90% of incubation period. Model used statistical distributions for inputs including susceptibility to the disease, donation rates, frequency and duration of travel to the UK, France and other countries in Europe since 1980, the effectiveness of donor deferral policies and infectivity clearance during manufacturing processes.
Results: For severe hemophilia patients at the highest risk (prophylaxis, with inhibitor, with immune tolerance) the model estimated annual mean exposure to be ~7 x 10-8 iv ID50 or ~1 in 270,000 with the lower prevalence (4 per million) assumption, and ~1 x 10-4 iv ID50 or ~1 in 12,000 with the higher prevalence (1 per 4,225) assumption. Donor deferral policies reduce the risk by >92%.
Discussion: Due to limited data and knowledge of vCJD, the model estimates are uncertain. However, it suggests the risk is small, and donor deferral and manufacturing processes greatly reduce the risk.

Serial passage of sCJD in humanised transgenic mice indicates two major transmission strains associated with PrPSc of either type 1 or 2
Matthew Bishop, Robert Will, Enrico Cancellotti, Jean Manson University of Edinburgh, UK
Background: Questions remain about the aetiology of sporadic CJD and whether phenotypic variation is solely controlled by factors such as codon 129 genotype and biochemistry of PrPC. Variation in infective strain has not been clearly demonstrated in sCJD.
Objectives: By serial passage of sCJD in transgenic mice expressing human prion protein with MM, MV, and VV codon 129 genotypes we aimed to understand strain transmission characteristics for the three most commonly observed phenotypes of sCJD.
Methods: We performed intracerebral inoculation of humanised transgenic mice with brain homogenates derived from similar mice previously inoculated with frontal cortex from sCJD patients of subgroups MM1, MV2, and VV2. These mice were assessed for clinical TSE signs, for TSE vacuolation, and deposition of PrPSc.
Results: sCJD(MM1) passage via all mice showed transmission profiles similar to primary inoculation. sCJD(MV2) passage via HuMM and HuVV mice showed a transmission profile similar to primary inoculation. Passage via a HuMV mouse showed transmission properties similar to not only the primary inoculum but also sCJD(MM1). sCJD(VV2) passage via HuMV and HuVV mice showed transmission profiles similar to the primary inoculation. Passage via a HuMM mouse showed transmission properties similar to not only the sCJD(VV2) primary inoculum but also sCJD(MM1). Cluster analysis of the lesion profile data showed that three clusters seen after primary inoculation were reduced to two following second passage, identified by the biochemical type of PrPSc (1 or 2) found in the host mice.
Discussion: Serial passage of sCJD subgroups MM1, MV2, and VV2 shows that PrPSc type and mouse codon 129 genotype determine the secondary transmission profile, independently of the originating inoculum strain. There are associations between type 1 PrPSc and C129-Met, and type 2 PrPSc and C129-Val. This should allow us to investigate further the relationship between PrPSc, genotype, infection, and pathology.

Detection of cellular prion protein (PrPc) in plasma from healthy cynomolgus monkeys (Macaca fascicularis) and changes observed after BSE infection
Barbara Yutzy, Edgar Holznagel, Johannes Löwer Paul-Ehrlich-Institut, Germany
Background: Orally BSE-dosed cynomolgus monkeys represent a valuable model to examine the kinetic of blood infectivity and to assess the risk of blood-borne transmission of variant Creutzfeldt-Jacob disease (vCJD).
Methods: Blood samples were collected monthly from BSE-infected (n = 18) and non-infected female cynomolgus monkeys (n = 8) over a period of up to 9 years. PrPc concentrations were retrospectively analyzed in plasma samples by a dot blot assay and by a sandwich ELISA using a highly sensitive dissociation- enhanced lanthanide fluoro-immunoassay (DELFIA) for detection. Different blood preparation protocols were evaluated to obtain plasma.
Objective: To detect changes in the levels of soluble plasmaderived PrPc. Results: Different blood preparation protocols had a significant effect on the measured plasma PrPc concentrations. In non-infected macaques, concentrations of soluble, plasmaderived PrPc were at least 10-fold lower compared to plasma concentrations in healthy humans. Levels of plasma PrPc increased 6 – 12 months after experimental BSE infection, remained high during the asymptomatic phase, and dropped towards the clinical phase. Soluble, plasma-derived PrPc molecules were PK-sensitive in BSE-infected macaques.
Discussion: There is a species-specific difference in the PrPc concentrations between human and macaque. At least a part of the plasma-derived PrPc fraction originates from blood cells. Andfinally, BSE infection caused an increase in plasma PrPc levels during the asymptomatic phase of infection. Blood transfusion studies have been initiated to examine whether these PK-sensitive PrP molecules carry infectivity.

Office of Inspector General Semiannual Report to Congress FY 2007 - 2nd Half
Two Texas Companies Sentenced and Fined for Misbranding Meat Products In April 2007, two closely held and related Texas companies pled guilty in Federal court and were sentenced to 12 months of probation and ordered to pay $10,250 in fines for misbranding meat products. One of the companies sold adulterated meat products to a retail store in New Mexico. Additionally, portions of the invoices failed to properly and consistently identify the meat products as being from cattle more than 30 months old at time of slaughter. This information is required to be disclosed because of bovine spongiform encephalopathy (BSE, or "mad cow disease") concerns. No adulterated meat reached consumers.
