Advisory Committee; Transmissible Spongiform Encephalopathies Advisory Committee; Termination

 

AGENCY: Food and Drug Administration, HHS.

 

ACTION: Final rule.

 

-----------------------------------------------------------------------

 

SUMMARY: The Food and Drug Administration (FDA) is announcing the termination of the Transmissible Spongiform Encephalopathies Advisory Committee. This document removes the Transmissible Spongiform Encephalopathies Advisory Committee from the Agency's list of standing advisory committees.

 

DATES: This rule is effective June 9, 2016.

 

FOR FURTHER INFORMATION CONTACT: Bryan Emery, Division of Scientific Advisors and Consultants, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 71, Rm. 6132, Silver Spring, MD 20993-0002, 240- 402-8054, FAX: 301-595-1307, or bryan.emery@fda.hhs.gov.

 

SUPPLEMENTARY INFORMATION: The Transmissible Spongiform Encephalopathies Advisory Committee (the Committee) was established on June 9, 1995 (60 FR 31311, June 14, 1995; 21 CFR 14.100 erroneously lists the date of establishment as June 21, 1995). The Committee reviews and evaluates available scientific data concerning the safety of products that may be a risk for transmission of spongiform encephalopathies having an impact on the public health as determined by the Commissioner of Food and Drugs. The Committee makes recommendations to the Commissioner regarding the regulation of such products. In recent years, the number of issues requiring Committee advice has declined, and the Committee has met very infrequently. Therefore, the effort and expense of maintaining this advisory committee is no longer justified. Any relevant Transmissible Spongiform Encephalopathy issues in the future could be addressed by the Agency's other advisory committees, such as the Agency's Blood Products Advisory Committee, with additional augmentation of expertise by appropriate subject matter experts serving as temporary members on the committee. The Committee is no longer needed and will be terminated on June 9, 2016. Under 5 U.S.C. 553(b)(3)(B) and (d) and 21 CFR 10.40 (d) and (e), the Agency finds good cause to dispense with notice and public comment procedures and to proceed to an immediate effective date on this rule. Notice and public comment and a delayed effective date are unnecessary and are not in the public interest as this final rule merely removes the name of the Transmissible Spongiform Encephalopathies Advisory Committee from the list of standing advisory committees in 21 CFR 14.100. Therefore, the Agency is amending 21 CFR 14.100(b) as set forth in the regulatory text of this document.

 

List of Subjects in 21 CFR Part 14

 

 Administrative practice and procedure, Advisory committees, Color additives, Drugs, Radiation protection.

 

 Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs, 21 CFR part 14 is amended as follows:

Chronic wasting disease (CWD) is a widespread and highly transmissible prion disease in free-ranging and captive cervid species in North America. The zoonotic potential of CWD prions is a serious public health concern, but the susceptibility of human CNS and peripheral organs to CWD prions remains largely unresolved. We reported earlier that peripheral and CNS infections were detected in transgenic mice expressing human PrP129M or PrP129V. Here we will present an update on this project, including evidence for strain dependence and influence of cervid PrP polymorphisms on CWD zoonosis as well as the characteristics of experimental human CWD prions.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD) disease in human. To date, BSE agent is the only recognized zoonotic prion. Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that have been circulating for centuries in farmed ruminants there is no apparent epidemiological link between exposure to ruminant products and the occurrence of other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD). However, the zoonotic potential of the diversity of circulating TSE agents has never been systematically assessed. The major issue in experimental assessment of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the biological phenomenon that limits TSE agents’ propagation from a species to another. In the last decade, mice genetically engineered to express normal forms of the human prion protein has proved essential in studying human prions pathogenesis and modeling the capacity of TSEs to cross the human species barrier.

 

To assess the zoonotic potential of prions circulating in farmed ruminants, we study their transmission ability in transgenic mice expressing human PrPC (HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC (129Met or 129Val) are used to determine the role of the Met129Val dimorphism in susceptibility/resistance to the different agents.

 

These transmission experiments confirm the ability of BSE prions to propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be susceptible to BSE in sheep or goat to a greater degree than the BSE agent in cattle and that these agents can convey molecular properties and neuropathological indistinguishable from vCJD. However homozygous 129V mice are resistant to all tested BSE derived prions independently of the originating species suggesting a higher transmission barrier for 129V-PrP variant.

 

Transmission data also revealed that several scrapie prions propagate in HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the efficiency of transmission at primary passage was low, subsequent passages resulted in a highly virulent prion disease in both Met129 and Val129 mice. Transmission of the different scrapie isolates in these mice leads to the emergence of prion strain phenotypes that showed similar characteristics to those displayed by MM1 or VV2 sCJD prion. These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.

 


 

IL-13 Transmission of prions to non human-primates: Implications for human populations

Prion diseases are the unique neurodegenerative proteinopathies reputed to be transmissible under field conditions since decades. The transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that an animal prion disease might be zoonotic under appropriate conditions. Contrarily, in the absence of obvious (epidemiological or experimental) elements supporting a transmission or genetic predispositions, prion diseases, like the other proteinopathies, are reputed to occur spontaneously (atypical animal prion strains, sporadic CJD summing 80 % of human prion cases).

 

Non-human primate models provided the first evidences supporting the transmissibility of human prion strains and the zoonotic potential of BSE. Among them, cynomolgus macaques brought major information for BSE risk assessment for human health1, according to their phylogenetic proximity to humans and extended lifetime. We used this model to assess the risk of primary (oral) and secondary (transfusional) risk of BSE, and also the zoonotic potential of other animal prion diseases from bovine, ovine and cervid origins even after very long silent incubation periods.

 

We recently observed the direct transmission of a natural classical scrapie isolate to macaque after a 10-year silent incubation period, with features similar to some reported for human cases of sporadic CJD, albeit requiring fourfold' . longer incubation than BSE2. Scrapie, as recently evoked in humanized mice3, is the third potentially zoonotic prion disease (with BSE and L-type BSE4), thus questioning the origin of human sporadic cases. We also observed hidden prions transmitted by blood transfusion in primate which escape to the classical diagnostic methods and extend the field of healthy carriers. We will present an updated panorama of our different long-term transmission studies and discuss the implications on risk assessment of animal prion diseases for human health and of the status of healthy carrier5.

Curriculum Vitae

 

Dr. Deslys co-authored more than one hundred publications in international scientific journals on main aspects of applied prion research (diagnostic, decontamination techniques, risk assessment, and therapeutic approaches in different experimental models) and on underlying pathological mechanisms. He studied the genetic of the first cases of iatrogenic CJD in France. His work has led to several patents including the BSE (Bovine Spongiform Encephalopathy) diagnostic test most widely used worldwide. He also wrote a book on mad cow disease which can be downloaded here for free (http://www.neuroprion.org/pdf_docs/documentation/madcow_deslys.pdf). His research group is Associate Laboratory to National Reference Laboratory for CJD in France and has high security level microbiological installations (NeuroPrion research platform) with different experimental models (mouse, hamster, macaque). The primate model of BSE developed by his group with cynomolgus macaques turned out to mimick remarkably well the human situation and allows to assess the primary (oral) and secondary (transfusional) risks linked to animal and human prions even after very long silent incubation periods. ***For several years, his interest has extended to the connections between PrP and Alzheimer and the prion mechanisms underlying neurodegenerative diseases. He is coordinating the NeuroPrion international association (initially european network of excellence now open to all prion researchers).

*** The potential impact of prion diseases on human health was greatly magnified by the recognition that interspecies transfer of BSE to humans by beef ingestion resulted in vCJD. While changes in animal feed constituents and slaughter practices appear to have curtailed vCJD, there is concern that CWD of free-ranging deer and elk in the U.S. might also cross the species barrier. Thus, consuming venison could be a source of human prion disease. Whether BSE and CWD represent interspecies scrapie transfer or are newly arisen prion diseases is unknown. Therefore, the possibility of transmission of prion disease through other food animals cannot be ruled out. There is evidence that vCJD can be transmitted through blood transfusion. There is likely a pool of unknown size of asymptomatic individuals infected with vCJD, and there may be asymptomatic individuals infected with the CWD equivalent. These circumstances represent a potential threat to blood, blood products, and plasma supplies.

Interpretive Summary: The transmissible spongiform encephalopathies (also called prion diseases) are fatal neurodegenerative diseases that affect animals and humans. The agent of prion diseases is a misfolded form of the prion protein that is resistant to breakdown by the host cells. Since all mammals express prion protein on the surface of various cells such as neurons, all mammals are, in theory, capable of replicating prion diseases. One example of a prion disease, bovine spongiform encephalopathy (BSE; also called mad cow disease), has been shown to infect cattle, sheep, exotic undulates, cats, non-human primates, and humans when the new host is exposed to feeds or foods contaminated with the disease agent. The purpose of this study was to test whether non-human primates (cynomologous macaque) are susceptible to the agent of sheep scrapie. After an incubation period of approximately 10 years a macaque developed progressive clinical signs suggestive of neurologic disease. Upon postmortem examination and microscopic examination of tissues, there was a widespread distribution of lesions consistent with a transmissible spongiform encephalopathy. This information will have a scientific impact since it is the first study that demonstrates the transmission of scrapie to a non-human primate with a close genetic relationship to humans. This information is especially useful to regulatory officials and those involved with risk assessment of the potential transmission of animal prion diseases to humans. Technical Abstract: Classical bovine spongiform encephalopathy (c-BSE) is an animal prion disease that also causes variant Creutzfeldt-Jakob disease in humans. Over the past decades, c-BSE's zoonotic potential has been the driving force in establishing extensive protective measures for animal and human health.

 

*** In complement to the recent demonstration that humanized mice are susceptible to scrapie, we report here the first observation of direct transmission of a natural classical scrapie isolate to a macaque after a 10-year incubation period. Neuropathologic examination revealed all of the features of a prion disease: spongiform change, neuronal loss, and accumulation of PrPres throughout the CNS.

 

*** This observation strengthens the questioning of the harmlessness of scrapie to humans, at a time when protective measures for human and animal health are being dismantled and reduced as c-BSE is considered controlled and being eradicated.

 

*** Our results underscore the importance of precautionary and protective measures and the necessity for long-term experimental transmission studies to assess the zoonotic potential of other animal prion strains.

 


 

why do we not want to do TSE transmission studies on chimpanzees $

 

5. A positive result from a chimpanzee challenged severly would likely create alarm in some circles even if the result could not be interpreted for man. I have a view that all these agents could be transmitted provided a large enough dose by appropriate routes was given and the animals kept long enough. Until the mechanisms of the species barrier are more clearly understood it might be best to retain that hypothesis.

”The occurrence of CWD must be viewed against the contest of the locations in which it occurred. It was an incidental and unwelcome complication of the respective wildlife research programmes. Despite it’s subsequent recognition as a new disease of cervids, therefore justifying direct investigation, no specific research funding was forthcoming. The USDA veiwed it as a wildlife problem and consequently not their province!” page 26.

Dear Mr Elmhirst,

 

CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT

 

Thank you for your recent letter concerning the publication of the third annual report from the CJD Surveillance Unit. I am sorry that you are dissatisfied with the way in which this report was published.

 

The Surveillance Unit is a completely independant outside body and the Department of Health is committed to publishing their reports as soon as they become available. In the circumstances it is not the practice to circulate the report for comment since the findings of the report would not be amended. In future we can ensure that the British Deer Farmers Association receives a copy of the report in advance of publication.

 

The Chief Medical Officer has undertaken to keep the public fully informed of the results of any research in respect of CJD. This report was entirely the work of the unit and was produced completely independantly of the the Department.

 

The statistical results reqarding the consumption of venison was put into perspective in the body of the report and was not mentioned at all in the press release. Media attention regarding this report was low key but gave a realistic presentation of the statistical findings of the Unit. This approach to publication was successful in that consumption of venison was highlighted only once by the media ie. in the News at one television proqramme.

 

I believe that a further statement about the report, or indeed statistical links between CJD and consumption of venison, would increase, and quite possibly give damaging credence, to the whole issue. From the low key media reports of which I am aware it seems unlikely that venison consumption will suffer adversely, if at all.

Dear Sir/Madam,

 

In the Archives of Neurology you quoted (the abstract of which was attached to your email), we did not say CWD in humans will present like variant CJD. That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

*** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).

***Moreover, L-BSE has been transmitted more easily to transgenic mice overexpressing a human PrP [13,14] or to primates [15,16] than C-BSE.

 

***It has been suggested that some sporadic CJD subtypes in humans may result from an exposure to the L-BSE agent.

 

*** Lending support to this hypothesis, pathological and biochemical similarities have been observed between L-BSE and an sCJD subtype (MV genotype at codon 129 of PRNP) [17], and between L-BSE infected non-human primate and another sCJD subtype (MM genotype) [15].

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.

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

Abstract

 

Although Bovine Spongiform Encephalopathy (BSE) is the cause of variant Creutzfeldt Jakob disease (vCJD) in humans, the zoonotic potential of scrapie prions remains unknown. Mice genetically engineered to overexpress the human ​prion protein (tgHu) have emerged as highly relevant models for gauging the capacity of prions to transmit to humans. These models can propagate human prions without any apparent transmission barrier and have been used used to confirm the zoonotic ability of BSE. Here we show that a panel of sheep scrapie prions transmit to several tgHu mice models with an efficiency comparable to that of cattle BSE. The serial transmission of different scrapie isolates in these mice led to the propagation of prions that are phenotypically identical to those causing sporadic CJD (sCJD) in humans. These results demonstrate that scrapie prions have a zoonotic potential and raise new questions about the possible link between animal and human prions.

Scrapie Field Trial Experiments Mission, Texas

 

A Scrapie Field Trial was developed at Mission, Texas, to provide additional information for the eradication program on the epidemiology of natural scrapie. The Mission Field Trial Station is located on 450 acres of pastureland, part of the former Moore Air Force Base, near Mission, Texas. It was designed to bring previously exposed, and later also unexposed, sheep or goats to the Station and maintain and breed them under close observation for extended periods to determine which animals would develop scrapie and define more closely the natural spread and other epidemiological aspects of the disease.

 

The 547 previously exposed sheep brought to the Mission Station beginning in 1964 were of the Cheviot, Hampshire, Montadale, or Suffolk breeds. They were purchased as field outbreaks occurred, and represented 21 bloodlines in which scrapie had been diagnosed. Upon arrival at the Station, the sheep were maintained on pasture, with supplemental feeding as necessary. The station was divided into 2 areas: (1) a series of pastures and-pens occupied by male animals only, and (2) a series of pastures and pens occupied by females and young progeny of both sexes. ...

The purpose of this work was to determine susceptibility of white-tailed deer (WTD) to the agent of sheep scrapie and to compare the resultant PrPSc to that of the original inoculum and chronic wasting disease (CWD). We inoculated WTD by a natural route of exposure (concurrent oral and intranasal (IN); n D 5) with a US scrapie isolate. All scrapie-inoculated deer had evidence of PrPSc accumulation. PrPSc was detected in lymphoid tissues at preclinical time points, and deer necropsied after 28 months post-inoculation had clinical signs, spongiform encephalopathy, and widespread distribution of PrPSc in neural and lymphoid tissues. Western blotting (WB) revealed PrPSc with 2 distinct molecular profiles. WB on cerebral cortex had a profile similar to the original scrapie inoculum, whereas WB of brainstem, cerebellum, or lymph nodes revealed PrPSc with a higher profile resembling CWD. Homogenates with the 2 distinct profiles from WTD with clinical scrapie were further passaged to mice expressing cervid prion protein and intranasally to sheep and WTD. In cervidized mice, the 2 inocula have distinct incubation times. Sheep inoculated intranasally with WTD derived scrapie developed disease, but only after inoculation with the inoculum that had a scrapie-like profile. The WTD study is ongoing, but deer in both inoculation groups are positive for PrPSc by rectal mucosal biopsy. In summary, this work demonstrates that WTD are susceptible to the agent of scrapie, 2 distinct molecular profiles of PrPSc are present in the tissues of affected deer, and inoculum of either profile readily passes to deer.

White-tailed Deer are Susceptible to Scrapie by Natural Route of Infection

 

Jodi D. Smith, Justin J. Greenlee, and Robert A. Kunkle; Virus and Prion Research Unit, National Animal Disease Center, USDA-ARS

 

Interspecies transmission studies afford the opportunity to better understand the potential host range and origins of prion diseases. Previous experiments demonstrated that white-tailed deer are susceptible to sheep-derived scrapie by intracranial inoculation. The purpose of this study was to determine susceptibility of white-tailed deer to scrapie after a natural route of exposure. Deer (n=5) were inoculated by concurrent oral (30 ml) and intranasal (1 ml) instillation of a 10% (wt/vol) brain homogenate derived from a sheep clinically affected with scrapie. Non-inoculated deer were maintained as negative controls. All deer were observed daily for clinical signs. Deer were euthanized and necropsied when neurologic disease was evident, and tissues were examined for abnormal prion protein (PrPSc) by immunohistochemistry (IHC) and western blot (WB). One animal was euthanized 15 months post-inoculation (MPI) due to an injury. At that time, examination of obex and lymphoid tissues by IHC was positive, but WB of obex and colliculus were negative. Remaining deer developed clinical signs of wasting and mental depression and were necropsied from 28 to 33 MPI. Tissues from these deer were positive for scrapie by IHC and WB. Tissues with PrPSc immunoreactivity included brain, tonsil, retropharyngeal and mesenteric lymph nodes, hemal node, Peyer’s patches, and spleen. This work demonstrates for the first time that white-tailed deer are susceptible to sheep scrapie by potential natural routes of inoculation. In-depth analysis of tissues will be done to determine similarities between scrapie in deer after intracranial and oral/intranasal inoculation and chronic wasting disease resulting from similar routes of inoculation.

PO-039: A comparison of scrapie and chronic wasting disease in white-tailed deer

White-tailed deer are susceptible to the agent of sheep scrapie by intracerebral inoculation

 

snip...

 

It is unlikely that CWD will be eradicated from free-ranging cervids, and the disease is likely to continue to spread geographically [10]. However, the potential that white-tailed deer may be susceptible to sheep scrapie by a natural route presents an additional confounding factor to halting the spread of CWD. This leads to the additional speculations that

 

1) infected deer could serve as a reservoir to infect sheep with scrapie offering challenges to scrapie eradication efforts and

 

2) CWD spread need not remain geographically confined to current endemic areas, but could occur anywhere that sheep with scrapie and susceptible cervids cohabitate.

 

This work demonstrates for the first time that white-tailed deer are susceptible to sheep scrapie by intracerebral inoculation with a high attack rate and that the disease that results has similarities to CWD. These experiments will be repeated with a more natural route of inoculation to determine the likelihood of the potential transmission of sheep scrapie to white-tailed deer. If scrapie were to occur in white-tailed deer, results of this study indicate that it would be detected as a TSE, but may be difficult to differentiate from CWD without in-depth biochemical analysis.

The results of this study suggest that there are many similarities in the manifestation of CWD and scrapie in WTD after IC inoculation including early and widespread presence of PrPSc in lymphoid tissues, clinical signs of depression and weight loss progressing to wasting, and an incubation time of 21-23 months. Moreover, western blots (WB) done on brain material from the obex region have a molecular profile similar to CWD and distinct from tissues of the cerebrum or the scrapie inoculum. However, results of microscopic and IHC examination indicate that there are differences between the lesions expected in CWD and those that occur in deer with scrapie: amyloid plaques were not noted in any sections of brain examined from these deer and the pattern of immunoreactivity by IHC was diffuse rather than plaque-like.

 

*** After a natural route of exposure, 100% of WTD were susceptible to scrapie.

 

Deer developed clinical signs of wasting and mental depression and were necropsied from 28 to 33 months PI. Tissues from these deer were positive for PrPSc by IHC and WB. Similar to IC inoculated deer, samples from these deer exhibited two different molecular profiles: samples from obex resembled CWD whereas those from cerebrum were similar to the original scrapie inoculum. On further examination by WB using a panel of antibodies, the tissues from deer with scrapie exhibit properties differing from tissues either from sheep with scrapie or WTD with CWD. Samples from WTD with CWD or sheep with scrapie are strongly immunoreactive when probed with mAb P4, however, samples from WTD with scrapie are only weakly immunoreactive. In contrast, when probed with mAb’s 6H4 or SAF 84, samples from sheep with scrapie and WTD with CWD are weakly immunoreactive and samples from WTD with scrapie are strongly positive. This work demonstrates that WTD are highly susceptible to sheep scrapie, but on first passage, scrapie in WTD is differentiable from CWD.

*** We describe the transmission of spongiform encephalopathy in a non-human primate inoculated 10 years earlier with a strain of sheep c-scrapie. Because of this extended incubation period in a facility in which other prion diseases are under study, we are obliged to consider two alternative possibilities that might explain its occurrence. We first considered the possibility of a sporadic origin (like CJD in humans). Such an event is extremely improbable because the inoculated animal was 14 years old when the clinical signs appeared, i.e. about 40% through the expected natural lifetime of this species, compared to a peak age incidence of 60–65 years in human sporadic CJD, or about 80% through their expected lifetimes.

 

***Moreover, sporadic disease has never been observed in breeding colonies or primate research laboratories, most notably among hundreds of animals over several decades of study at the National Institutes of Health25, and in nearly twenty older animals continuously housed in our own facility.***

CJD/BSE (aka madcow) Human/Animal TSE’s--U.S.--Submission To Scientific Advisors and Consultants Staff January 2001 Meeting (short version)

 

Greetings again Dr. Freas and Committee Members,

 

I wish to submit the following information to the Scientific Advisors and Consultants Staff 2001 Advisory Committee (short version).

 

I understand the reason of having to shorten my submission, but only hope that you add it to a copy of the long version, for members to take and read at their pleasure, (if cost is problem, bill me, address below). So when they realize some time in the near future of the 'real' risks i speak of from human/animal TSEs and blood/surgical products. I cannot explain the 'real' risk of this in 5 or 10 minutes at some meeting, or on 2 or 3 pages, but will attempt here:

 

remember AIDS/HIV, 'no problem to heterosexuals in the U.S.? no need to go into that, you know of this blunder:

 

DO NOT make these same stupid mistakes again with human/animal TSE's aka MADCOW DISEASE. I lost my Mom to hvCJD, and my neighbor lost his Mother to sCJD as well (both cases confirmed). I have seen many deaths, from many diseases. I have never seen anything as CJD, I still see my Mom laying helpless, jerking tremendously, and screaming "God, what's wrong with me, why can't I stop this". I still see this, and will never forget. Approximately 10 weeks from 1st of symptoms to death. This is what drives me. I have learned more in 3 years about not only human/animal TSE's but the cattle/rendering/feeding industry/government than i ever wished to.

 

I think you are all aware of CJD vs vCJD, but i don't think you all know the facts of human/animal TSE's as a whole, they are all very very similar, and are all tied to the same thing, GREED and MAN.

 

I am beginning to think that the endless attempt to track down and ban, potential victims from known BSE Countries from giving blood will be futile. You would have to ban everyone on the Globe eventually? AS well, I think we MUST ACT SWIFTLY to find blood test for TSE's, whether it be blood test, urine test, .eyelid test, anything at whatever cost, we need a test FAST.

 

DO NOT let the incubation time period of these TSEs fool you.

 

To think of Scrapie as the prime agent to compare CJD, but yet overlook the Louping-ill vaccine event in 1930's of which 1000's of sheep where infected by scrapie from a vaccine made of scrapie infected sheep brains, would be foolish. I acquired this full text version of the event which was recorded in the Annual Congress of 1946 National Vet. Med. Ass. of Great Britain and Ireland. from the BVA and the URL is posted in my (long version).

 

U.S.A. should make all human/animal TSE's notifiable at all ages, with requirements for a thorough surveillance and post-mortem examinations free of charge, if you are serious about eradicating this horrible disease in man and animal.

 

There is histopathology reports describing o florid plaques" in CJD victims in the USA and some of these victims are getting younger. I have copies of such autopsies, there has to be more. PLUS, sub-clinical human TSE's will most definitely be a problem.

 

THEN think of vaccineCJD in children and the bovine tissues used in the manufacturing process, think of the FACT that this agent surviving 6OO*C. PNAS -- Brown et al. 97 (7): 3418 scrapie agent live at 600*C

 

Then think of the CONFIDENTIAL documents of what was known of human/animal TSE and vaccines in the mid to late 80s, it was all about depletion of stock, to hell with the kids, BUT yet they knew. To think of the recall and worry of TSE's from the polio vaccine, (one taken orally i think?), but yet neglect to act on the other potential TSE vaccines (inoculations, the most effective mode to transmit TSEs) of which thousands of doses were kept and used, to deplete stockpile, again would be foolish.

 

--Oral polio; up to 1988, foetal calf serum was used from UK and New Zealand (pooled); since 1988 foetal calf serum only from New Zealand. Large stocks are held.

 

--Rubella; bulk was made before 1979 from foetal calf serum from UK and New Zealand. None has been made as there are some 15 years stock.

 

--Diphtheria; UK bovine beef muscle and ox heart is used but since the end of 1988 this has been sourced from Eire. There are 1,250 litres of stock.

 

--Tetanus; this involves bovine material from the UK mainly Scottish. There are 21,000 litres of stock.

 

--Pertussis; uses bovine material from the UK. There are 63,000 litres of stock. --They consider that to switch to a non-UK source will take a minimum of 6-18 months and to switch to a non-bovine source will take a minimum of five years.

 

3. XXXXXXXXXXX have measles, mumps, MMR, rubella vaccines. These are sourced from the USA and the company believes that US material only is used.

BSE3/1 0251

 

4. XXXXXXXXXXX have a measles vaccine using bovine serum from the UK. there are 440,000 units of stock. They have also got MMR using bovine serum from the UK.

 

5. XXXXXXXXXXX have influenza, rubella, measles,' MMR vaccines likely to be used in children. Of those they think that only MMR contains bovine material which is probably a French origin.

 

6. XXXXXXXXXXX have diphtheria/tetanus and potasses on clinical trial. hese use veal material, some of which has come from the UK and has been ade by XXXXXXXXXXX (see above).

 

I have documents of imports from known BSE Countries, of ferments, whole blood, antiallergenic preparations,

human blood plasma, normal human blood sera, human immune blood sera, fetal bovine serum, and other blood fractions not elsewhere specified or included, imported glands, catgut, vaccines for both human/animal, as late as 1998. Let us not forget about PITUITARY EXTRACT. This was used to help COWS super ovulate. This tissue was considered to be of greatest risk of containing BSE and consequently transmitting the disease.

 

ANNEX 6

 

MEETING HELD ON 8 JUNE 1988 TO DISCUSS THE IMPLICATIONS OF BSE TO BIOLOGICAL PRODUCTS CONTAINING BOVINE - EXTRACTED MATERIAL

 

How much of this was used in the U.S.?

 

Please do not keep making the same mistakes; 'Absence of evidence is not evidence of absence'.

 

What are the U.S. rules for importing and manufacturing vaccines, medicines and medical devices?

 

Does the U.S.A. allow sourcing of raw material of ruminants from the U.S.A.?

 

U.S. cattle, what kind of guarantee can you give for serum or tissue donor herds? . The U.S. rendering system would easily amplify T.S.E.'s:

 

Have we increased the stability of the system (improved heat treatments) since the EU SSC report on the U.S.A. was published in july 2000?

 

What is done to avoid cross-contaminations in the U.S.A.?

 

How can the U.S. control absence of cross-contaminations of animal TSE's when pig and horse MBM and even deer and elk are allowed in ruminant feed, as well as bovine blood? I sadly think of the rendering and feeding policy before the Aug. 4, 1997 'partial' feed ban, where anything went, from the city police horse, to the circus elephant, i will not mention all the scrapie infected sheep. I am surprised that we have not included man 'aka soyent green'. It is a disgusting industry and nothing more than greed fuels it.

 

When will the U.S.. start real surveillance of the U.S. bovine population (not passive, this will not work)?

 

When will U.S. start removing SRMs?

 

Have they stopped the use of pneumatic stunners in the U.S.?

 

If so, will we stop it in all U.S. abattoirs or only in those abattoirs exporting to Europe?

 

If not, WHY NOT?

 

same questions for removal of SRM in the U.S.A., or just for export?

 

If not, WHY NOT?

 

How do we now sterilize surgical/dental instruments in the U.S.A.?

 

Where have we been sourcing surgical catgut?

 

(i have copies of imports to U.S., and it would floor you) hen will re-usable surgical instruments be banned?

 

'Unregulated "foods" such as 'nutritional supplements' containing various extracts from ruminants, whether imported or derived from

 

3

 

US cattle/sheep/cervids ("antler velvet" extracts!) should be forbidden or at least very seriously regulated. (neighbors Mom, whom also died from CJD, had been taking bovine based supplement, which contained brain, eye, and many other bovine/ovine tissues for years, 'IPLEX').

 

What is the use of banning blood or tissue donors from Germany, France, etc... when the U.S.A. continues exposing cattle, sheep and people to SRM, refuses to have a serious feed ban, refuses to do systematic BSE-surveillance?

 

The FDA should feel responsible for the safety of what people eat, prohibit the most dangerous foods, not only prohibit a few more donors - the FDA should be responsible for the safe sourcing of medical devices, not only rely on banning donors "from Europe", The 'real' risks are here in the U.S. as well, and nave been for some time.

 

We must not forget the studies that have proven infectivity in blood from TSE's.

 

The Lancet, November 9, 1985

 

Sir, --Professor Manuelidis and his colleagues (Oct 19, p896) report transmission to animals of Creutzfeldt-Jakob disease (CJD) from the buffy coat from two patients. We also transmitted the disease from, whole blood samples of a patient (and of mice) infected with CJD.l Brain, Cornea, and urine from this patient were also infectious, and the clinicopathological findings2 are summarised as follows.

 

snip...

 

Samples,were taken aseptically at necropsy. 10% crude homogenates of brain and cornea in saline, whole blood (after crushing a clot), and untreated CSF and urine were innoculated intracerebrally into CFl strain mice (20 ul per animal). Some mice showed emaciation, bradykinesia, rigidity of the body and tail, and sometimes tremor after long incubation periods. Tissues obtained after the animal died (or was killed) were studied histologically (table). Animals infected by various inocula showed common pathological changes, consisting of severe spongiform changes, glial proliferation, and a moderate loss of nerve cells. A few mice inoculated with brain tissue or urine had the same amyloid plaques found in patients and animals with CJD.3

and

 

CWD and transmission to man will be no different than other TSE's.

 

"Clearly, it is premature to draw firm conclusions about CWD passing naturally into humans, cattle and sheep, but the present results suggest that CWD transmissions to humans would be as limited by PrP incompatibility as transmissions of BSE or sheep scrapie to humans. Although there is no evidence that sheep scrapie has affected humans, it is likely that BSE has

caused variant CJD in 74 people (definite and probable variant CJD cases to date according to the UK CJD Surveillance Unit). Given the presumably large number of people exposed to BSE infectivity, the susceptibility of humans may still be very low compared with cattle, which would be consistent with the relatively inefficient conversion of human PrP-sen by PrPBSE. Nonetheless, since humans have apparently been infected by BSE, it would seem prudent to take reasonable measures to limit exposure of humans (as well as sheep and cattle) to CWD infectivity as has been recommended for other animal TSEs,"

Transmission of BSE by blood transfusion in sheep

 

Lancet 2000; 356: 999 – 1000

See Commentary

 

"We have shown that it is possible to transmit bovine spongiform encephalopathy (BSE) to a sheep by transfusion with whole blood taken from another sheep during the symptom-free phase of an experimental BSE infection. BSE and variant Creutzfeldt-Jakob disease (vCJD) in human beings are caused by the same infectious agent, and the sheep-BSE experimental model has a similar pathogenesis to that of human vCJD. Although UK blood transfusions are leucodepleted--a possible protective measure against any risk from blood transmission-- this report suggests that blood donated by symptom-free vCJD-infected human beings may represent a risk of spread of vCJD infection among the human population of the UK."

 

"The demonstration that the new variant of Creutzfeldt-Jakob disease (vCJD) is caused by the same agent that causes bovine spongiform encephalopathy (BSE) in cattle1 has raised concerns that blood from human beings in the symptom-free stages of vCJD could transmit infection to recipients of blood transfusions (full text long version)"

 

and...

 

"The large number of cases (1040), temporal clustering of the outbreaks (15 in the first 6 months of 1997), the high in-flock incidence, and the exceptional involvement of goats (390 cases), suggested an accidental infection. The source of the epidemic might have been TSE-contaminated meat and bonemeal, but eight flocks had never been fed any commercial feedstuff. Infection might have risen from the use of a formol-inactivated vaccine against contagious agalactia prepared by a single laboratory with brain and mammary gland homogenates of sheep infected with Mycoplasma agalactiae. Although clinical signs of TSE in the donor sheep have not been found, it is possible that one or more of them were harbouring the

infectious agent. Between 1995 and 1996, this vaccine was given subcutaneously to 15 of the affected flocks (to one flock in 1994) ; in these animals the disease appeared between 23 and 35 months after vaccination. No information is available for herd 13 because it was made up of stolen animals. Sheep from the remaining three flocks (1-3, figure) did not receive the vaccine, thus suggesting a naturally occurring disease.’’ (again, full text long version).

 

IN SHORT, please do under estimate this data and or human/animal TSE's including CWD in the U.S.A.

 

A few last words, please.

 

The cattle industry would love to have us turn our focus to CWD and forget about our own home grown TSE in Bovines. This would be easy to do. Marsh's work was from downer cattle feed, NOT downer deer/elk feed. This has been proven.

 

DO NOT MAKE THAT MISTAKE.

 

There should be NO LESS THAN 1,000,000 tests for BSE/TSE ' in 2001 for U.S.A. French are testing 20,000 a week. The tests are available. Why wait until we stumble across a case from passive surveillance, by then it is to late. IF we want the truth, this is a must???

(hmmm, i am thinking why there is not a variant scrapie, that is totally different than all the rest)? just being sarcastic.

 

with only PARTIAL FEED BAN implemented on Aug. 4, 1997??? (you really need to reconsider that blood meal etc. 'TOTAL BAN')

 


 

AND PLEASE FOR GODS SAKE, STOP saying vCJD victims are the only ones tied to this environmental death sentence. "PROVE IT". It's just not true. The 'CHOSEN ONES' are not the only ones dying because of this man-made death sentence. When making regulations for human health from human/animal TSEs, you had better include ALL human TSE's, not just vCJD. Do NOT underestimate sporadic CJD with the 'prehistoric' testing available to date. This could be a deadly mistake. Remember, sCJD kills much faster from 1st onset of symptoms to death, and hvCJD is the fastest. Could it just be a higher titre of infectivity, or route or source, or all three?

 

Last, but not least. The illegal/legal harvesting of body parts and tissues will come back to haunt you. Maybe not morally, but due to NO background checks and human TSEs, again it will continue to spread.

 

Stupidity, Ignorance and Greed is what fuels this disease. You must stop all of this, and ACT AT ONCE...

TO : william.freas@fda.hhs.gov

 


 

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 bottomline, 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 itas being prudent to take serious and immediate action ;

 


 


 

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

 

Singeltary, Sr et al. JAMA.2001; 285: 733-734. Vol. 285 No. 6, February 14, 2001 JAMA

 

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

 

To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.
