The board of the Irish Blood Transfusion Service will discuss at its next
meeting whether it can go ahead with plans to ban blood donations
from this month
from anyone who spent a year in the
United Kingdom between 1980 and 1996.
In March this year, in response to concerns about the dangers of patients
contracting variant Creutzfeldt-Jakob disease (vCJD) from donated
blood, the service banned donations from anyone who had spent five
years in Britain, which led to a drop of 20% in blood supplies and
growing concern about shortages.
The transfusion service's deputy chief executive, Andy Kelly, recently said
that there was a real risk of a crisis if the fall off in donations
was not reversed.
Several European countries have restricted donations from citizens who have
spent time in Britain. Austria, Finland, France, and Germany
as well as the United States, Canada,
Australia, New Zealand, and Japan
are deferring donors who have lived in the
United Kingdom during the relevant years. The United States, which has
further tightened its restrictions, is also concerned about shortages
(see article below).
Ireland's second phase restrictions would hit particularly hard: a survey of
Irish donors by the transfusion service showed that about 80% had
visited the United Kingdom at some time between 1980 and
1999 and that 13% had lived there for six months or more.
The service's chief executive, Martin Hynes, has said that the full scale
banning of donations "would decimate the Irish blood supply."
The service was one of the first in Europe to use leucodepletion
the removal of white cells from blood
to minimise the theoretical risk
of vCJD transmission.
Meanwhile a spokesman from the English Department of Health, which still
accepts donations from the groups being banned by other countries,
said that they had done all they could to reduce the risk in the
United Kingdom. All blood has undergone leucodepletion for the past
three years, he said.
"We have followed the scientific advice that we had to reduce the risks
of transmission. We now take out the white cells from the
blood," he said.
"We have got to have a balance between an unknown risk and whether
people need this blood. We need the blood. We don't know how big the
risk is."
All blood plasma products now come from the United States, he added.
The health department was also considering whether it might further reduce
any risk by refusing blood donations from people who had already
received a blood transfusion, he added.
