COMPARING THE RELATIVE RISK OF vCJD TRANSMISSION VIA PLASMA
The Department of Health asked SEAC for advice on a methodology for assessing the risks of using single unit plasma as opposed to pooled plasma, either sourced from the UK or non-UK source countries.
SEAC noted that there are many large uncertainties around the potential risk of transmission of vCJD via the use of plasma products. However, as the relative risks (as opposed to absolute risks) posed by plasma products were being estimated, uncertainties around the timing, level and distribution of infectivity in blood of an infected person would not appreciably affect the estimations. The best way to manage other major uncertainties, such as those around the prevalence of vCJD in the UK and other countries, would be to develop a range of scenarios incorporating reasonable high and low value estimates for such parameters.
vCJD INFECTION IN A HAEMOPHILIAC AT POST MORTEM
SEAC considered data from investigations of a Haemophilia patient who had been shown on post mortem to have the abnormal prion protein associated with vCJD in his spleen (as reported recently by the Health Protection Agency2). In view of the fact that preliminary unpublished data were considered, this issue was discussed in a reserved business session in accordance with the SEAC Code of Practice.
SEAC agreed that, although the patient had not shown clinical signs of vCJD prior to death, this finding provides evidence of vCJD infection. It would appear more likely at this stage that the infection occurred from the administration of clotting factors prepared from the plasma of a donor who had later developed vCJD than from dietary exposure to BSE.

SEAC noted that IBNC appeared to be a rare disease that occurred in older cattle, predominantly as single cases, although it is possible that surveillance may not detect all cases. Biochemical studies suggested that the prion protein may play a role in the disease. However, it is unclear whether the normal form of the protein or an abnormal form is involved. Studies are required to determine whether IBNC is transmissible or not. SEAC concluded, noting that specified risk material controls are in place to prevent cattle brain from entering the food supply, that current data on IBNC do not suggest it presents a risk to human health.

30. The Committee noted that the results were unusual. the questioned whether there could be coincidental BSE infection or contamination with scrapie. Dr. Tyrell noted that the feeling of the committee was that this did not represent a new agent but it was important to be prepared to say something publicly about these findings. A suggested line to take was that these were scientifically unpublishable results but in line with the policy of openness they would be made publicly available and further work done to test their validity. Since the BSE precautions were applied to IBNC cases, human health was protected. Further investigations should be carried out on isolations from brains of IBNC cases with removal of the brain and subsequent handling under strict conditions to avoid the risk of any contamination.
31. Mr. Bradley informed the Committee that the CVO had informed the CMO about the IBNC results and the transmission from retina and he, like the Committee was satisfied that the controls already in place or proposed were adequate. ...

HUMAN and ANIMAL TSE Classifications i.e. mad cow disease and the UKBSEnvCJD only theory JUNE 2008
snip...
Tissue infectivity and strain typing of the many variants Manuscript of the human and animal TSEs are paramount in all variants of all TSE. There must be a proper classification that will differentiate between all these human TSE in order to do this. With the CDI and other more sensitive testing coming about, I only hope that my proposal will some day be taken seriously. ...

Abstract:
TSEs have been rampant in the USA for decades in many species, and they all have been rendered and fed back to animals for human/animal consumption. 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 2007. snip...
