First case of vCJD reported in a Japanese patient

The first case of variant Creutzfeldt-Jakob disease (vCJD) in a Japanese
patient was announced by the Japanese Ministry of Health, Labour and
Welfare on 4 February 2005 [1]. The patient, who first experienced
neurological symptoms in December 2001, and died in December 2004, was
male and in his 40s.

The patient is reported to have spent approximately one month in the
United Kingdom in 1988, although the exact length of his stay has not
yet been confirmed. The possibility of exposure to the vCJD infective
agent while the patient was in the UK is widely accepted at present.

On 16 September 2004, the Japanese CJD surveillance panel, in
collaboration with the United Kingdom National CJD surveillance unit
(http://www.cjd.ed.ac.uk/) diagnosed an isolated form of CJD, and
confirmed the need to further observe the developing symptoms.

On 3 February 2005, the CJD sub-committee reported that the
characteristic findings of the post-mortem pathological investigation,
which included a western blot, strongly indicated vCJD. A genetic
mutation of the prion protein has not been detected.

There are no records of the patient ever having received a blood
transfusion. Records of the Japanese Red Cross Society are still being
checked to determine whether he ever donated blood.

There is ongoing further investigation into the cause of this case and
the possibility of secondary transmission. The public is being provided
with accurate information regarding vCJD.

Following the announcement of this case, the Japanese Pharmaceutical and
Food Safety Bureaus Blood and Blood Products Steering Committee have
maintained restrictions on blood donors who have lived in the UK, but
these will be regularly reviewed. The Japanese Red Cross Society has
been instructed to refuse donations from people who have lived in the UK
for longer than one month.

Japan first reported cases of bovine spongiform encephalopathy (BSE) in
farmed cows in 2001 and 14 cases of BSE were reported between 2001 and
2004 [3,4]. After the first case, the import, production and use of meat
and bone meal was banned, and Japan implemented a programme of testing
every carcass for BSE, and removing specified risk materials. It also
suspended beef imports from countries with BSE.
