Transmissible Spongiform Encephalopathies Advisory Committee;
[FR Doc. 04-21282 Filed 9-21-04; 8:45 am] (TSS SUB. short version 10/4/04)

Greetings Dr. Freas, Dr. Langford, Dr. Smallwood and all FDA,

I WISH to make the following submission and comments about all
topics of this meeting about human/animal TSEs. My comments and
submissions as follows please;

>>>>USDA-licensed tests for the diagnosis of bovine
>>>>spongiform encephalopathy (BSE) and other transmissible spongiform
>>>>encephalopathies (TSE),

IN the past all we have heard is the fact that the present BSEs test
do not guarantee public health safety. I request that the USA implement a
BSE/TSE test that DOES guarantee public health safety, one approved for
protection, a test for live cattle, one that would detect all TSEs in the
bovine, one that would detect sub clinical TSEs; EFSA Scientific Report
on the Design of a Field Trial Protocol for the Evaluation of BSE Tests for
Live Cattle This report provides a protocol for the design
of a field trial protocol for the evaluation of BSE tests for live cattle
for the purpose of consumer protection only.

>>>> review of the worldwide BSE situation,

THE most disturbing factor of this topic are the new atypical TSEs
showing up in not only cattle, but also sheep, and no one knows yet
about how many different strains of cwdTSE in deer/elk. WITH evidence of
sporadic CJD being very similar to these atypical TSEs in cattle and sheep,
and the findings from Asante, Collinge et al that BSE prions propagate
as either nvCJD or sporadic CJD, the ramifications of these findings are
very very worrisome and should not go ignored any further. WITH
the fact that there are over 20 documented strains of scrapie, and the
most logical hypothesis is scrapie to BSE, why would one believe in
only one phenotype of TSE in the bovine. IN fact, we have a new study
of two distinct prion strains derived from BSE in mice. YOU must not
continue to ignore these studies;

BSE prions propagate as either variant CJD-like or sporadic CJD-like
prion strains in transgenic mice expressing human prion protein

ONE of the things i have been most worried about and will continue to
bring to the attention of the TSE advisory committee is the continued
denial of the potential of transmission of sporadic CJD via blood and
blood products. THERE are studies showing infectivity in the blood of
sporadic CJD, and just how many phenotypes there are of sporadic CJD is
anyone's guess at this point in time. WE have already documented
transmission of sporadic CJD via tissues and organs. TO continue the
BSE/nvCJD only theory will only continue to spread this agent. WE must
move away from this mentality and move on with all TSEs and treat all
TSEs as one, until proven otherwise, not the other way around. with
6,000 'DEAR nvCJD LETTERS' due to blood and blood products so far, i can
only imagine the number, once sporadic CJD is documented to have
transmitted via blood, what that number will be when those 'DEAR
SPORADIC CJD LETTERS' go out and how many will become clinical once
exposed, a frightening thought. OR, has infection by sporadic CJD
already happened, i don't think they are too sure if the 2nd
_infection_ of CJD was sporadic or variant;

transfusion-associated infection with vCJD

MOST importantly, the 1968 MEDICINES ACT where it states 'NO SAF' was
blatantly ignored,
for animals and humans.

the inactivated polio vaccine is no longer being used. There is a stock
of smallpox vaccine. We have not been able to determine the source
material. (Made in sheep very unlikely to contain bovine ingredients).

Blood from four of 37 human beings with clinically evident sporadic CJD has
reported to transmit the disease after intracerebral inoculation into
mice, or hamsters. But each success has been questioned on technical grounds
and has not been reproducible;

Transmission of Creutzfeldt-Jakob Disease from Blood and Urine Into Mice

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.1
Brain, Cornea, and urine from this patient were also infectious, and
the clinicopathological findings2 are summarised as follows.

This observation represents the first documented transmission of BSE

Extraneural Pathologic Prion Protein in Sporadic Creutzfeldt-Jakob Disease


Conclusions Using sensitive techniques, we identified extraneural
of PrPSc in spleen and muscle samples from approximately one third of
who died with sporadic Creutzfeldt-Jakob disease. Extraneural PrPSc appears
to correlate with a long duration of disease.

Prions in skeletal muscle (Prusiner et al)

EMBO reports AOP Published online: 11 April 2003 Widespread PrPSc
accumulation in muscles of hamsters orally infected with scrapie

How much is too much? How much is not enough? What about accumulation?
What is the Threshold of exposure, to infectivity, to clinical disease?
How many strains/phenotype does sporadic CJD consist of and
What is the infectivity of each one of those phenotypes (cwdCJD)?
Until these questions are answered, you are gambling, nothing more.
I just pray that you get it right...

ALL human/animal TSEs should be made reportable Nationally and
ALL human TSE victims (family) should fill out mandatory CJD Questionnaire.

thank you,
