B. Koneru et al., BLOOD-TRANSFUSIONS IN LIVER RECIPIENTS - A CONUNDRUM OR A CLEAR BENEFIT IN THE CYCLOSPORINE TACROLIMUS ERA/, Transplantation, 63(11), 1997, pp. 1587-1590
Blood transfusions are common in patients with end-stage liver disease
(ESLD), and their effects on sensitization, rejection, and liver graf
t survival are not well known. These effects were examined in 121 reci
pients of primary liver grafts, surviving greater than or equal to 30
days. Ninety-six (79%) patients received transfusions before transplan
tation. Transfusion recipients had significantly fewer severe or recur
rent rejection episodes (18%), compared with patients who did not rece
ive transfusions (42%, P=0.006), if the first transfusion was greater
than or equal to 90 days before the transplant. Patients with alcoholi
c ESLD (n=49) had significantly fewer severe rejection episodes when c
ompared with the nonalcoholic (n=72) patients (12% vs. 35%, P=0.004).
The transfusion benefit was, however, more apparent and significant in
the nonalcoholic (26% vs. 56% in nontransfused, P=0.02) than among th
e alcoholic recipients (6% vs. 25%, P=0.1). This finding is, most like
ly, due to a combination of a higher rate of severe rejection and the
statistical power of the larger number of recipients in the nonalcohol
ic group. This finding is further corroborated by a multivariate analy
sis in which blood transfusions retained their benefit (P<0.05) indepe
ndent of recipient's age and diagnosis. Graft and patient survival wer
e not significantly different in the transfused versus nontransfused g
roups. Transfusion recipients had a higher panel antibody (11.4+/-23.4
vs. 2.7+/-8.1, P<0.02) but no increased risk of a positive crossmatch
. In liver recipients, blood transfusions diminish the risk of rejecti
on independent of recipient's age and the cause of ESLD.
