More Proof vCJD, Prion
Diseases Spread Via Blood
2nd Person May Have CJD Via Blood Transfusion
From Patricia Doyle, PhD

A 2nd possible case of a patient contracting variant Creutzfeldt-Jakob disease [abbreviated as CJD (new var.) or vCJD in ProMED-mail] through a blood transfusion has been confirmed, the Department of Health (DOH) said today. The patient received a blood transfusion in 1999 from a donor who later went on to develop vCJD -- the human form of bovine spongiform encephalopathy (BSE) or "mad cow disease".
The DoH said the patient died of causes unrelated to vCJD, but a post-mortem revealed the presence of the vCJD agent in the spleen, according to the National CJD Surveillance Unit. The development followed the 1st reported case of a patient contracting vCJD from a blood transfusion which was announced by Health Secretary John Reid in December 2003. The patient, who received donor blood during an operation in 1997, developed vCJD and died 6 years later.
In response to that case -- thought to be the 1st person-to-person transmission of vCJD in the world -- the Government banned anyone who had received a blood transfusion since January 1980 from donating blood in the future. The DoH said today that it was now extending measures to cover a larger group of transfusion recipients who will no longer be allowed to give blood from 2 Aug 2004.
Dr Reid said today, "We are continuing to follow a highly precautionary approach. Although people may have concerns about the implications of this announcement, I would emphasise again that the exclusion criteria are being tightened because of a small but unquantifiable risk. People should continue to have a blood transfusion when it is really necessary. Any slight risk associated with receiving blood must be balanced against the significant risk of not receiving that blood when it is most needed."
