CBER 2007 Annual Report Assessing the Potential Risk of variant Creutzfeldt-Jakob Disease from Blood Products

Assessing the Potential Risk of variant Creutzfeldt-Jakob Disease from Blood Products

A rare but fatal brain infection called variant Creutzfeldt-Jakob Disease (vCJD) has emerged in recent years as a potential threat to recipients of plasma-derived clotting factors and other plasma-derived products, such as immune globulin and albumin. CBER developed a computer-assisted model for estimating this risk to recipients of plasma-derived clotting factors in order to ensure that both patients and physicians understand this issue. This model was developed to assess the risk of U.S.-licensed, plasma-derived Factor VIII products and a plasma-derived Factor XI manufactured in the United Kingdom and used under IND in a small number of patients in the U.S. between 1989 and 2000. The results of the risk assessments and communication strategies were presented to FDA's Transmissible Spongiform Encephalopathies (TSE) Advisory Committee in September and December 2006.

Based on the risk assessments, the Public Health Service (PHS) believes the risk of vCJD to patients who receive U.S.-licensed, plasma-derived Factor VIII products is extremely small, although PHS does not know the risk with certainty. vCJD risk from other U.S.-licensed, plasma-derived products, including Factor IX, is likely to be as small or smaller. Additionally, the PHS believes the potential risk of vCJD infection from plasma-derived Factor XI, although not known for certain, is likely to be small.

Furthermore, CBER developed and implemented a risk communication plan in order to ensure the findings of the risk assessments reached the appropriate stakeholders. CBER partnered with patient advocates and risk communication experts to develop educational materials and arranged for hemophilia treatment centers and professional and advocacy organizations to publicize the findings through newsletters and other media. Finally, CBER launched a web page (http://www.fda.gov/cber/blood/vcjdrisk.htm) that provides the risk assessments and risk communication materials. Additional links are provided to FDA's current guidance documents on deferral of blood and plasma donors who may be at increased risk of vCJD and to other sources of information on vCJD.

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 ;

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 ;

Greetings again Dr. Freas et al at FDA,

WITH new atypical TSE in the bovine, in the sheep, goat, and humans, and the fact that the new BASE TSE in cattle being very very similar to sporadic CJD, rather than the nvCJD, the fact that now science showing the TSE agent of the atypical cattle in Japan showing infectivity other than CNS tissue, the fact that the latest Texas mad cow and the recent Alabama mad cow both being of the atypical strain, it would seem prudent to include all human TSE in the blood ban, in my opinion. with sporadic CJD, you have many strains and or phenotypes, some of which are 'UNKNOWN', so we do not know how this will transmit, what tissues are infectious and or if blood transmits. that's the bottom line, however it has been reported that the BASE is more virulent to humans. With this, and the fact that sporadic CJD has tripled in the past few years or so, i see it as being prudent to take serious and immediate action ;

SEAC agreed that there is considerable work to be done to characterise fully this new disease, its cause and whether it is infectious or not. As preliminary unpublished data were also presented, this issue was discussed in a reserved business session in accordance with the SEAC Code of Practice.RESULTS ON HUMAN SCLERASEAC considered preliminary results provided by the HPA and National CJD Surveillance Unit from tests on eye tissue (sclera) from a vCJD case. The results suggest the presence of infectivity and, in contrast with previous testing of samples from other vCJD cases, abnormal prion protein in this tissue. However, as the sclera is very difficult to remove from surrounding eye tissues, which are themselves known to carry vCJD infectivity, the findings may have arisen as a result of contamination at autopsy. Nevertheless, even if the data are reliable, they indicate that there may only be a relatively low level of infectivity present in sclera. As preliminary unpublished data were considered, this issue was discussed in a reserved business session in accordance with the SEAC Code of Practice.5 Gambetti et al.

A New Prionopathy OR more of the same old BSe and sporadic CJD

Communicated by: Terry S. Singeltary Sr.[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.

The Prion’s Elusive Reason for Being


Annu. Rev. Neurosci. 2008. 31:439–77First published online as a Review in Advance onApril 2, 2008

Abstract The protein-only hypothesis posits that the infectious agent causing transmissible spongiform encephalopathies consists of protein and lacks any informational nucleic acids. This agent, termed prion by Stanley Prusiner, is thought to consist partly of PrPSc, a conformational isoform of a normal cellular protein termed PrPC. Scientists and lay persons have been fascinated by the prion concept, and it has been subjected to passionate critique and intense experimental scrutiny. As a result, PrPC and its isoforms rank among the most intensively studied proteins encoded by the mammalian genome. Despite all this research, both the physiological function of PrPC and the molecular pathways leading to neurodegeneration in prion disease remain unknown. Here we review the salient traits of those diseases ascribed to improper behavior of the prion protein and highlight how the physiological functions of PrPC may help explain the toxic phenotypes observed in prion disease.

It is important to note, however, that the above considerations apply primarily to the epidemiology of primary transmission from cows to humans. Although, by now a pool of preclinically infected humans may have been built. Human-to-human transmission may present with characteristics very different from those of primary cow-to-human transmission, including enhanced virulence, shortened incubation times, disrespect of allelic PRNP polymorphisms (129MM, MV or VV), and heterodox modes of infection including blood-borne transmission. If we account for the time it will take to eradicate these secondary transmissions in the population, vCJD is not likely to disappear entirely in the coming four decades. Iatrogenic CJD. Iatrogenic CJD is accidentally transmitted during the course of medical or surgical procedures. The first documented case of iatrogenic prion transmission occurred in 1974 and was caused by corneal transplantation of a graft derived from a patient suffering from sCJD (Duffy et al. 1974). Iatrogenic CJD is also rare, most often observed in individuals that have received cadaveric dura mater implants and human growth hormone; some of these individuals received gonadotrophin extracted from human pituitary glands or had stereotactically placed electrodes in their brains (Will 2003). Four cases of vCJD transmission by blood transfusions have been reported recently in the United Kingdom (Llewelyn et al. 2004, Peden et al. 2004, Wroe et al. 2006) (see also http://www.cjd.ed.ac.uk/TMER/TMER.htm ). The fact that preclinically infected individuals can transmit vCJD underscores the important medical need for sensitive diagnostic tools, which could be used for screening blood units prior to transfusion, for example.
