Universal Leukocyte Reduction of Blood Transfusion Components

     EAST HILLS, N.Y.--(BW HealthWire)--Sept. 21, 1998--
 
     A New Level of Safety for America's Blood Supply
 
By a vote of 13 to 0, the Food and Drug Administration's Blood
Products Advisory Committee (BPAC) approved a recommendation that,
"the benefit to risk ratio associated with leukoreduction is
sufficiently great to justify routine leukoreduction of all
non-leukocyte transfusion blood components.... ." Filtering blood
before transfusion removes leukocytes (white blood cells), thereby
reducing the risk of transmitting into the body a number of bacteria
and viruses, as well as reducing adverse transfusion reactions and
improving patient outcomes.

"This recommendation is a milestone which will lead to
significantly increasing the safety of the US blood supply," said
Barry Wenz, MD, Corporate Medical Director and Vice President of Pall
Corporation (NYSE: PLL). The establishment of universal leukocyte
reduction is already the policy of the United Kingdom, France,
Austria, Norway, Malta, Ireland and Portugal. Canada filters all
platelets and a growing proportion of red cells.
 
Benefits of Leukocyte Reduction
 
Multiple viruses (including cytomegalovirus (CMV), Human T-cell
Lymphotrophic Virus (HTLV-1) and Epstein-Barr virus) and bacteria
(including Yersinia) are harbored in white blood cells. Blood donors
are routinely screened for only a few of these contaminants.
Filtration is an important line of defense against these agents and,
perhaps, other emerging or yet-to-be discovered viruses or bacteria.
Leukocyte reduction has been shown in scientific studies to reduce the
number of infectious agents in blood components. Pall's leukocyte
reduction filters reduce the risk of transmitting many of these
pathogens and complement current screening procedures.

Unfiltered blood transfusions have a major negative impact on the
immune systems of all recipients. Clinical studies have shown that
leukocyte reduction reduces transfusion-related suppression of the
immune system and helps protect against post-surgical infection. Use
of leukoreduced blood components has resulted in a reduction of both
morbidity and mortality of surgical patients, as well as a significant
decrease in the length of hospital stay and costs. An additional risk
for patients, such as those with cancer and leukemia who require
platelet transfusions, is platelet refractoriness, in which patients
develop antibodies which disable the platelets they need. Leukocytes
are responsible for this life-threatening complication which can be
effectively reduced by filtration.
 
Blood Filtration in the United States
 
In the United States, about 12 million units of blood are
collected each year for the one in 20 people who will need a
transfusion in their lifetime. Currently, some 60 to 70 percent of
platelet units and 20 percent of red blood cell units are filtered by
individual hospitals and blood centers, which have made the decision
to provide this extra measure of protection for their patients.
