EMA Position Statement on plasma/urine products 2011




- Human TSEs current status




sCJD, gCJD, iCJD





Epidemiological evidence does not support transmission of s, g, iCJD by blood, blood components or plasma products




No case of sCJD, gCJD, iCJD has been causally linked to prior treatment with plasma products or blood transfusion




* It cannot formally excluded the possibility of blood transmission in a small number of cases based:



* -limitations in statistical power of epidemiological studies



* -limited experimental evidence of peripherical tissue infectivity in various subtypes of sCJD



* -potential diagnostic confusion



* Cases of sCJD with treatment of infertility have not been identified,



* -uncertainty about the validity of this observation



* -strength of evidence of exclusion transmission by urine products is less secure




vCJD



Number of cases:

Jun-04 146 6 1 1 1 1 156





Source NCJDRSU-University of Edinburgh














Still uncertainties on the number of cases of vCJD that will occur




UK figures for the quarterly incidence of deaths may indicate that vCJD incidence in the UK is in decline -> caution interpretation




All definitive and probable cases are Met/Met Codon 129 PrP gene




In 2009, one possible case vCJD Met/Val but could not be confirmed as autopsy was not performed









vCJD





Importance of estimation of vCJD prevalence with respect to any potential

secondary transmission while individuals are in the incubation phase



Estimated prevalence of the disease in different UK studies:



- 267 infections / million (95% CI [49-692]) (Hilton et al. 2004))



- 0-113 (95%; 1961-1995 birth cohort) (Clevlew et al. 2009)



- 109 infection / million (95% CI [3-608]) (De Marco et al. 2010)





Infectivity/ transmissibility via blood





Animal blood




Low levels of infectivity found in the blood of rodents infected with

TSE agents.




Half of infectivity is in cellular components, mainly buffy coat




Orally infected sheep or natural scrapie can be transmitted by blood

transfusion in the majority of cases collected half way through incubation period




Experiments on BSE infected sheep demonstrate that all blood components,

incl. plasma contain transmissible TSE agent and remain infectious

after leucoreduction






Human blood




Strong evidence that vCJD is transmissible through blood transfusion




Four instances of secondary transmission in blood transfusion from UK donors




- received non-leucodepleted transfusions from healthy donors that

developed vCJD 17-40 months later




- 3 recipients developed vCJD (6.5-8.5 years later)




- 1 heterozygous case died 5 yr. later by unrelated causes

and tested positive for PrPTSE in spleen




Infectivity in human blood of vCJD cases was not detected using the

methods capable of detecting in peripheral tissues (e.g. tonsil, spleen)





Human blood




Warning that some plasma derived products might contain

residual prion infectivity




Presumed case of asymptomatic vCJD infection identified in an elderly

haemophilic patient:




• heterozygous Met/Val.




• had received large quantities of intermediate purity UK-sourced factor VIII




• at least one batch included some units manufactured from a plasma

from a donor that later developed CJD




Risk assessment suggest that the most likely route of infection was the

reception of plasma products




These findings highlight the importance of national databases of blood

donors and the maintenance of an effective traceability donor/receptor system




donor <-> receptor





EMA Position Statement on plasma/urine products 2011





- Plasma products: Recommendations






Donor selection





Donor selection criteria should be implemented to minimise

the risk of developing CJD





sCJD, gCJD, iCJD





Donor selection criteria:





deferral of donors who might be at higher risk of developing CJD

(family history of TSE, corneal or dura mater graft receptors,

treated patients with medicines derived from human pituitary glands)





Donor exclusion criteria






vCJD





Country based donor selection criteria based on the identification

of high risk donors





UK





- donor exclusion who have spent long periods in UK





- recommended 1 year or more cumulative UK residence

between 1980-1996





- member States (MS) may define stricter limits but will accept

plasma products from other MS that at least 1 yr time limit is applied




France and other BSE-exposed MS





-not recommended exclusion of donors that spent cumulative periods

in these countries





• Additional further deferral criteria may be recommended

by MS






weighing the odds




safety impact vs donation volumes





Batch recall of plasma products




sCJD, gCJD, iCJD




Precautionary recalls for batches when post donation reports of CJD

or risk factors donors is NOT recommended




- not justified based on current epidemiological evidence




- risk of shortages of plasma products




vCJD




Maintenance of recommendation of batch recall where a donor to

a plasma pool subsequently develops vCJD.





vCJD




Maintenance of recommendation of batch recall where a donor to

a plasma pool subsequently develops vCJD




It applies for plasma products used as such or as excipients




The risk of infectivity transmission of albumin is particularly low




In case of albumin used as excipient or during manufacture

product recall should be considered




However, a case-by-case risk analysis taking into account the prion reduction

data and amount of albumin use could justify not needing a recall.




Plasma products used in manufacture of other medicinal products:

case–by-case consideration depending on nature, amount,

point of use in the manufacturing process.





Leucoreduction





Not appropriate to recommend the introduction of

leucoreduction steps at this moment in plasma for fractionation




• At the moment, the benefit of leucoreduction to improve safety of

plasma not demonstrated.





• UK implemented in 1999 in transfusion.





SCMPMD opinion is that:




Transfusion: might be a precautionary step




Fractionation: no compelling scientific evidence to introduce to

reduce vCJD transmission




Studies in infected hamsters showed only 42-72% reduction of

infectivity





No effective complete removal in blood of BSE sheeps






Affinity filters





The efficacy for introduction of affinity media / filter is still

under investigation.





Animal studies showed clearance capabilities of filter, resin matrix.





Oct 09 SaBTO stated that:





there was sufficient evidence of infectivity reduction by affinity

ligand filters





recommended use in children born since 1-Jan-1996

subject to satisfactory completion PRISM clinical trial





Data on prion binding capacity of an affinity ligand chromatography

step in a plasma product has been published. Further evaluation is

considered needed prior to conclusions can be drawn on possible

efficacy.






Manufacturing processes






Recommendation of estimation the potential

to reduce infectivity of manuf. processes





Stepwise approach based on:





Available relevant published data





Product specific investigational studies

on key steps





using biochemical assays is sufficient if

correlation with infectivity data has been

established







Warning Statements on CJD and plasma products






Standard texts for Warning Statements (WS) on transmissible agents

in the Summary of Product Characteristics (SmPC) and

Package leaflet (PL) for blood products.




In 2003, it was not recommended to include a specific reference to CJD

as this would give impression of increased concern about potential

transmissibility by plasma products.




In 2011, this recommendation is reconfirmed




CJD risk is already covered in the general texts:





image






“Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents CANNOT BE TOTALLY EXCLUDED. This also applies to unknown or emerging viruses and other pathogens.







Overview







EMA Position Statement on plasma/urine products 2011







- Urine products: Recommendations







TSE Urine: Current status







Presence of PrP in human urine has been reported. No evidence

that infectivity is present.






Low levels of TSE infectivity detected in urine in animal models

by several groups (incl. scrapie-infected rodents, deer with CWD).






Epidemiological evidence (>25 yrs) of use of urine products does not

suggest a risk form sCJD.






No epidemiological evidence of CJD/vCJD transmission by urine

products








Urine: Recommendations







Urine to be collected from countries where there is TSE surveillance

system, unless otherwise justified.






Use of exclusion criteria in donor selection is encouraged.

Feasible to apply donor selection in small well-defined donor

population






• Hormones: already in place by some manufacturers






• Urokinase: more difficult to apply






Same exclusion criteria for CJD/vCJD as for plasma donors

Manufacturers should follow up the donor criteria at defined intervals







Manufacturers are required to estimate the

potential reduction capacity of their manufacturing

processes






Same general stepwise approach as for plasma

-Extrapolation of results on investigational studies

of certain steps of plasma products is not justified






-Investigational studies should address prion:






- potential accumulation in chromatographic columns






- batch-to-batch contamination due to carry over






-If reduction capacity is limited, manufacturers should

consider including additional steps






Record keeping for traceability encouraged

when possible to trace back to donor

Greetings again Sporadic CJD victims and families around the globe.








here, we see the writing on the wall. the what if’s, again ???






now this report does mention sporadic CJD. but nothing about new science showing links between atypical BSE and atypical Scrapie with sporadic CJD, and the fact that atypical BSE much more virulent, and that it has a 50% shorter incubation period than typical BSE, and the link to sporadic CJD ??? this should be very disturbing to all. ...







To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

Seven main threats for the future linked to prions






First threat





The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed. ***Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.





Second threat

EFSA Journal 2011 The European Response to BSE: A Success Story






snip...







EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded. Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.

Transmission Results in Squirrel Monkeys Inoculated with Human sCJD, vCJD, and GSS Blood Specimens: the Baxter Study

Background: Rodent and sheep models of Transmissible Spongiform Encephalopathy (TSE) have documented blood infectivity in both the pre-clinical and clinical phases of disease. Results in a (presumably more appropriate) non-human primate model have not been reported.






Objective: To determine if blood components (red cells, white cells, platelets, and plasma) from various forms of human TSE are infectious.






Methods: Blood components were inoculated intra-cerebrally (0.1 ml) and intravenously (0.5 ml) into squirrel monkeys from 2 patients with sporadic Creutzfeldt- Jakob disease (sCJD) and 3 patients with variant Creutzfeldt-Jakob disease (vCJD). Additional monkeys were inoculated with buffy coat or plasma samples from chimpanzees infected with either sCJD or Gerstmann-Sträussler-Scheinker disease (GSS). Animals were monitored for a period of 5 years, and all dying or sacrificed animals had post-mortem neuropathological examinations and Western blots to determine the presence or absence of the misfolded prion protein (PrPTSE).






Results: No transmissions occurred in any of the animals inoculated with blood components from patients with sporadic or variant CJD. All donor chimpanzees (sCJD and GSS) became symptomatic within 6 weeks of their pre-clinical phase plasmapheresis, several months earlier than the expected onset of illness. One monkey inoculated with purified leukocytes from a pre-clinical GSS chimpanzee developed disease after 36 months.






Conclusion: No infectivity was found in small volumes of blood components from 4 patients with sporadic CJD and 3 patients with variant CJD. ***However, a single transmission from a chimpanzee-passaged strain of GSS shows that infectivity may be present in leukocytes, and the shock of general anaesthesia and plasmspheresis appears to have triggered the onset of illness in pre-clinical donor chimpanzees.

Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada





Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.





Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres.






Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis. Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.






Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. *** It also suggests a similar cause or source for atypical BSE in these countries.

Prion disease update 2010 (11) PRION DISEASE UPDATE 2010 (11)











October 2009 O.11.3 Infectivity in skeletal muscle of BASE-infected cattle







Silvia Suardi1, Chiara Vimercati1, Fabio Moda1, Ruggerone Margherita1, Ilaria Campagnani1, Guerino Lombardi2, Daniela Gelmetti2, Martin H. Groschup3, Anne Buschmann3, Cristina Casalone4, Maria Caramelli4, Salvatore Monaco5, Gianluigi Zanusso5, Fabrizio Tagliavini1 1Carlo Besta" Neurological Institute,Italy; 2IZS Brescia, Italy; 33FLI Insel Riems, D, Germany; 4CEA-IZS Torino, Italy; 5University of Verona, Italy



Background: BASE is an atypical form of bovine spongiform encephalopathy caused by a prion strain distinct from that of BSE. Upon experimental transmission to cattle, BASE induces a previously unrecognized disease phenotype marked by mental dullness and progressive atrophy of hind limb musculature. Whether affected muscles contain infectivity is unknown. This is a critical issue since the BASE strain is readily transmissible to a variety of hosts including primates, suggesting that humans may be susceptible.





Objectives: To investigate the distribution of infectivity in peripheral tissues of cattle experimentally infected with BASE. Methods: Groups of Tg mice expressing bovine PrP (Tgbov XV, n= 7-15/group) were inoculated both i.c. and i.p. with 10% homogenates of a variety of tissues including brain, spleen, cervical lymph node, kidney and skeletal muscle (m. longissimus dorsi) from cattle intracerebrally infected with BASE. No PrPres was detectable in the peripheral tissues used for inoculation either by immunohistochemistry or Western blot.






Results: Mice inoculated with BASE-brain homogenates showed clinical signs of disease with incubation and survival times of 175±15 and 207±12 days. Five out of seven mice challenged with skeletal muscle developed a similar neurological disorder, with incubation and survival times of 380±11 and 410±12 days. At present (700 days after inoculation) mice challenged with the other peripheral tissues are still healthy. The neuropathological phenotype and PrPres type of the affected mice inoculated either with brain or muscle were indistinguishable and matched those of Tgbov XV mice infected with natural BASE.






Discussion: Our data indicate that the skeletal muscle of cattle experimentally infected with BASE contains significant amount of infectivity, at variance with BSE-affected cattle, raising the issue of intraspecies transmission and the potential risk for humans. Experiments are in progress to assess the presence of infectivity in skeletal muscles of natural BASE.

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






A. Buschmann1, U. Ziegler1, M. Keller1, R. Rogers2, B. Hills3, M.H. 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.

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.













see where sporadic CJD cases went from 28 cases in 1990, to a high in 2008 of 88 cases of sporadic CJD, then 2009 dropped back a bit to 78 cases, and then in 2010 the sporadic CJD cases were back up to 84 cases. with a small rise in GSS and Familial cases of human TSE as well, through that time period ???

CJD Figures

These figures show the number of suspect cases referred to the NCJDRSU in Edinburgh, and the number of deaths of definite and probable cases in the UK, from 1 January 1990 up to 4th January 2012
see here ;
SO, we have atypical BSE and atypical Scrapie cases rising, we have sporadic CJD now linked to atypical BSE cases and atypical scrapie cases, and this report does not mention that $$$
BSe, and politics as usual $$$

National Prion Disease Pathology Surveillance Center Cases Examined (July 31, 2010)






(please watch and listen to the video and the scientist speaking about atypical BSE and sporadic CJD and listen to Professor Aguzzi)










THE steady rise of sporadic CJD cases in Canada AND USA, with many unusual cases of ''PENDING CLASSIFICATIONS" which have been pending now FOR 3 YEARS. HOW long can this cover-up continue $$$









The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.

November 29, 2006

Greetings FDA, DHH, Dr. Freas, and Dr. Harvey et al,

a kind and warm Holiday Greetings to you all.

i kindly wish to submit the following to the TSE advisory committee for the meeting December 15, 2006, about the assessment for potential exposure to vCJD in human plasma-derived antihemophilic factor (FVIII) products manufactured from U.S. plasma donors and related communication material ;

http://a257.g.akamaitech.net/7/257/2422/01jan20061800/edocket.access.gpo.gov/2006/E6-20251.htm


i see the media picked up on this as a 'low risk', from what the gov. agency perceived to be to them;
http://www.newsday.com/news/health/ats-ap_health14nov27,0,7955259.story?coll=ny-leadhealthnews-headlines


however, i seem to disagree. from my primitive ciphering, i see it another way. this is a huge catastrophic risk. 3 in 160 is 1.9%. so call that 2% which is 1 in 50 or twenty per thousand or 20,000 per million. also, what about the mixed genotypes/mixed susceptibility? what about the silent carriers that donated tainted blood? what about the sporadic CJDs of UNKNOWN strain or phenotype? this risk assessment is just more BSe to me. just another in a long line of industry fed crap. i pray that my assessment is the one that is wrong. but it is THEY who roll the dice with your life. it is THEY who refuse to regulate an industry that has run amok. just from a recall aspect of potentially tainted blood, and these are just recent recalls ;

Prion Disease Risks in the 21st Century 2011 PDA European Virus-TSE Safety Update on CJD and VCJD Transmission RG Will




Prion Disease Risks in the 21st Century 2011 PDA European Virus-TSE Safety






Subject: Update on CJD and VCJD Transmission RG Will
Greetings sporadic CJD victims et al in the UK, and around the globe.
 
 
Sadly, once again, the UK Prion Gods and nvCJD victims groups in the UK and EU have alienated the sporadic CJD victims and their families, and nothing says it more than RG Will, and his report to the Prion Disease Risks in the 21st Century 2011 PDA European Virus-TSE Safety. even though the report title states UPDATE ON CJD AND VCJD TRANSMISSION RG WILL, they play down to low key, with very little data at all on the recent science about sporadic CJD. you would think that with scientist around the globe saying that atypical BSE is now linked with some cases (if not all) of the sporadic CJD cases i.e. 85%+ of all human TSE, you would think that RG Will et al, and the victims group for nvCJD would all put their arms around these victims. BUT NO, instead, they alienate them as a happenstance of bad luck, and refuse to acknowledge update science, instead going by old and outdated science i.e. the UKBSEnvCJD only theory. I was hoping to finally see RG Will et al finally to speak about sporadic CJD and it’s links as a zoonosis disease, instead, we got nothing. IN this report to the industry pharmaceutical groups at the Prion Disease Risks in the 21st Century 2011 PDA European Virus-TSE Safety by RG Will titled : Update on CJD and VCJD Transmission RG Will, sporadic CJD was mentioned only ONE TIME, with a title to a paper trying once again to alienate sporadic CJD as being tied to blood even though the Baxter study DID tie GSS to blood ;
Transmission of sporadic Creutzfeldt Jakob Disease by blood transfusion: risk factor or possible biases
 
 
NO where else was sporadic CJD mentioned in this report. NO WHERE !
 
 
 
Its very sad that not only scientist like RG Will, but nvCJD victims groups in the UK and EU still to this day in 2012, still they all refuse to wrap their arms around these victims to of sporadic CJD. maybe it’s the risk of loosing any compensation, or maybe afraid if they mingle with the 85%+, they would loose out on compensation, even though I know that some refused this blood money, they still refuse to wrap their arms around the sporadic CJD victms, and stand up for them in public.
 
 
it’s sad when you can be bought off, or manipulated $$$
 
 
some day will come, when people like RG Will and his UKBSEnvCJD only theory, will have to eat crow, and I hope I am still alive to see it. ...

Greetings again sporadic CJD victims and their Families et al,
 
 
 
NOT A WORD ABOUT THE RISING SPORADIC CJD IN THE EU AND AROUND THE GLOBE, AND NEW LINKS TO ATYPICAL BSE AND ATYPICAL SCRAPIE TO HUMANS, not a word by RG WILL, in a paper he titled ;
 
 
 
Update on CJD and VCJD Transmission RG Will
 
 
 
SO, since RG Will either forgot, or refused to give the world his report on sporadic CJD, I thought I might. as follows ;
 
 
 
see where sporadic CJD cases went from 28 cases in 1990, to a high in 2008 of 88 cases of sporadic CJD, then 2009 dropped back a bit to 78 cases, and then in 2010 the sporadic CJD cases were back up to 84 cases. with a small rise in GSS and Familial cases of human TSE as well, through that time period ???

These figures show the number of suspect cases referred to the NCJDRSU in Edinburgh, and the number of deaths of definite and probable cases in the UK, from 1 January 1990 up to 4th January 2012
 
 
 
see here ;
 
 
 
 
 
 
SO, we have atypical BSE and atypical Scrapie cases rising, we have sporadic CJD now linked to atypical BSE cases and atypical scrapie cases, and this report does not mention that $$$

Transmission Results in Squirrel Monkeys Inoculated with Human sCJD, vCJD, and GSS Blood Specimens: the Baxter Study

Background: Rodent and sheep models of Transmissible Spongiform Encephalopathy (TSE) have documented blood infectivity in both the pre-clinical and clinical phases of disease. Results in a (presumably more appropriate) non-human primate model have not been reported.
 

Objective: To determine if blood components (red cells, white cells, platelets, and plasma) from various forms of human TSE are infectious.
 

Methods: Blood components were inoculated intra-cerebrally (0.1 ml) and intravenously (0.5 ml) into squirrel monkeys from 2 patients with sporadic Creutzfeldt- Jakob disease (sCJD) and 3 patients with variant Creutzfeldt-Jakob disease (vCJD). Additional monkeys were inoculated with buffy coat or plasma samples from chimpanzees infected with either sCJD or Gerstmann-Sträussler-Scheinker disease (GSS). Animals were monitored for a period of 5 years, and all dying or sacrificed animals had post-mortem neuropathological examinations and Western blots to determine the presence or absence of the misfolded prion protein (PrPTSE).
 

Results: No transmissions occurred in any of the animals inoculated with blood components from patients with sporadic or variant CJD. All donor chimpanzees (sCJD and GSS) became symptomatic within 6 weeks of their pre-clinical phase plasmapheresis, several months earlier than the expected onset of illness. One monkey inoculated with purified leukocytes from a pre-clinical GSS chimpanzee developed disease after 36 months.
 

Conclusion: No infectivity was found in small volumes of blood components from 4 patients with sporadic CJD and 3 patients with variant CJD. ***However, a single transmission from a chimpanzee-passaged strain of GSS shows that infectivity may be present in leukocytes, and the shock of general anaesthesia and plasmspheresis appears to have triggered the onset of illness in pre-clinical donor chimpanzees.

To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

Seven main threats for the future linked to prions
 


First threat
 


The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed.
 
 
***Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.
 
 


Second threat

EFSA Journal 2011 The European Response to BSE: A Success Story

snip...


EFSA and the European Centre for Disease Prevention and Control (ECDC) recently delivered a scientific opinion on any possible epidemiological or molecular association between TSEs in animals and humans (EFSA Panel on Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical BSE prions as the only TSE agents demonstrated to be zoonotic so far but the possibility that a small proportion of human cases so far classified as "sporadic" CJD are of zoonotic origin could not be excluded. Moreover, transmission experiments to non-human primates suggest that some TSE agents in addition to Classical BSE prions in cattle (namely L-type Atypical BSE, Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic wasting disease (CWD) agents) might have zoonotic potential.

P.9.21 Molecular characterization of BSE in Canada





Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada
 

Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.
 

Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres.
 


Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis. Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.
 

Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. *** It also suggests a similar cause or source for atypical BSE in these countries.

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.

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.

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.

In Creutzfeldt-Jakob disease (CJD), molecular typing based on the size of the protease resistant core of the disease-associated prion protein (PrPSc) and the M/V polymorphism at codon 129 of the PRNP gene correlates with the clinico-pathologic subtypes. Approximately 95% of the sporadic 129MM CJD patients are characterized by cerebral deposition of type 1 PrPSc and correspond to the classic clinical CJD phenotype. The rare 129MM CJD patients with type 2 PrPSc are further subdivided in a cortical and a thalamic form also indicated as Sporadic Fatal Insomnia.
 
 
 
We observed two young patients with MM2-thalamic CJD. Main neuropathological features were diffuse, synaptic PrP immunoreactivity in the cerebral cortex and severe neuronal loss and gliosis in the thalamus and olivary nucleus. Western blot analysis showed the presence of type 2A PrPSc. Challenge of transgenic mice expressing 129MM human PrP, showed that MM2-thalamic sCJD was able to transmit the disease, at variance with MM2-cortical sCJD. The affected mice showed deposition of type 2A PrPSc, a scenario that is unprecedented in this mouse line. These data indicate that MM2-thalamic sCJD is caused by a prion strain distinct from the other sCJD subtypes including the MM2-cortical form.
 
 
 
 
 
Case report Sporadic fatal insomnia in a young woman: A diagnostic challenge: Case Report

Case Presentation We report a case of a 33-year-old female who died of a prion disease for whom the diagnosis of sFI or FFI was not considered clinically. Following death of this patient, an interview with a close family member indicated the patient's illness included a major change in her sleep pattern, corroborating the reported autopsy diagnosis of sFI. Genetic tests identified no prion protein (PrP) gene mutation, but neuropathological examination and molecular study showed protease-resistant PrP (PrPres) in several brain regions and severe atrophy of the anterior-ventral and medial-dorsal thalamic nuclei similar to that described in FFI.
 
 
 
Conclusions
In patients with suspected prion disease, a characteristic change in sleep pattern can be an important clinical clue for identifying sFI or FFI; polysomnography (PSG), genetic analysis, and nuclear imaging may aid in diagnosis.

For the patient described in this report, her long duration of illness and young age at onset are unusual for the most common subtype of prion disease, sporadic CJD [17]. Other forms of CJD were considered but determined to be extremely unlikely. Although this young patient showed signs of psychiatric illness at the beginning of her disease consistent with variant CJD (vCJD), these signs did not precede her noticeable deficits in attention and memory and she had not traveled to any country where transmission of vCJD was known to occur.
 
 
 
snip...
 
 
 
Recently a case of alleged sFI has been reported showing the presence of PrPres type 1 (rather than type 2 as in the present and other cases of sFI); the largest amount of PrPres in the mediodorsal thalamic nucleus, and a glycoform ratio characterized by the relative prevalence of the diglycosylated PrPres isoform similar to that of FFI [23]. If confirmed, this case indicates that, as in sCJD in general, occasional and unexplained phenotypic variations have to be expected in sFI. Finally, the severe neuronal loss of the anterior ventral and mediodorsal thalamic nuclei which contained relatively low amounts of PrPres raises the issue of whether other isoforms of neurotoxic PrP such as protease-sensitive PrP are present in the thalamic nuclei in sFI.

Wickner, National Institutes of Health, Bethesda, MD, and approved May 19, 2010 (received for review April 15, 2010)


Next Section Abstract The biological determinants of the phenotypic variation in sporadic Creutzfeldt-Jakob disease (sCJD) are unknown. To categorize sCJD cases, the prion protein (PrP) codon 129 genotype and the biochemical characteristics of the disease-associated form of PrP (PrPSc) can be combined to form six subgroups (MM1, MM2, MV1, MV2, VV1, and VV2). This classification largely correlates with the known variation in the clinical and pathological features of sCJD, with the MM1 and MV1 cases representing the “classic” phenotype of sCJD. To address how this classification relates to different strains of sCJD we have inoculated each subgroup of sCJD to a panel of mice expressing different forms of the human PRNP gene (129MM, 129VV, and 129MV). We have established that all subtypes are transmissible to at least one genotype of mouse, and both agent and host factors determine transmission efficiency and the form of PrPSc deposited in the brain. Moreover, we have identified four distinct strains of sCJD using our in vivo strain typing panel.
 
 
 
snip...


Evidence in support of these four major strains of sCJD has recently been reported through a very different approach. Using in vitro assays, Uro-Coste et al. (29) examined the protease sensitivity and conformational stability of PrPSc found in 41 patients with sCJD and found groupings identical to those outlined in this study (i.e., MM1 and MV1; MV2 and VV2; MM2; VV1). Because this study was based entirely on in vitro analysis of PrPSc, this suggests that the four strains of agent identified in our study have different conformations of PrPSc. What is perhaps surprising is that only four discrete strains of sCJD have been identified. If the prion protein can exist in many different pathogenic isoforms in a single host, why then do only four different strains of sCJD result in humans? Because the assumption is that each sCJD case arises spontaneously, this would require strong selection factors to be operating for these four strains and against others that may be produced.
 
 
 
 
There are diverse suggestions as to the origin of sCJD, including proposals that somatic mutations lead to protein misfolding and disease (30) or that sCJD has arisen through infection from an animal source, such as atypical BSE (18, 31).
 
 
 
 
snip...
 
 
 
Our study evaluated the precise effect host PRNP codon 129 genotype has on defining transmission and propagation of sCJD strains in the three genotypes 129MM, 129MV, and 129VV. There were some specific combinations of host and inoculum within the dataset that showed similar characteristics across the experiments, such as the observation that the HuVV genotype line developed clinical TSE features with most inocula. HuVV mice also had the shortest incubation periods by more than 100 d, seen for sCJD(MV2) and sCJD(VV2) inocula. These data predict that for human iatrogenic spread of sCJD as a whole, this genotype may be the most susceptible or may show shorter incubation periods. It is of note that there is an increased prevalence of young (<50 y) VV genotype sCJD cases across European countries (United Kingdom, Germany, Italy, and France) (10). The second common characteristic among the data was that HuMM and HuMV mice had similar levels of clinical disease, and mean incubation periods, for four of the six inocula [excluding sCJD(MM2) and sCJD(VV1)]. This suggests that the methionine allele of PrPC in the heterozygous HuMV mice may have had a dominant effect over the valine allele PrPC with regard to the transmission properties. This study identifies two areas of risk in terms of developing sCJD. The first is that the highest risk of developing CJD after exposure to infection is from strain M1CJD [sCJD(MM1) or sCJD(MV1)] and that the VV genotype confers the highest risk of acquiring infection. The epidemiological findings in sCJD demonstrate that approximately 80% of patients are diagnosed with “classic CJD” types MM1 and MV1, which might intriguingly suggest an infectious rather than genetic origin for the majority of sCJD cases.

The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.
