Re. Shaddy et al., PERSISTENCE OF HUMAN-LEUKOCYTE ANTIGEN (HLA) ANTIBODIES AFTER ONE-YEAR IN CHILDREN RECEIVING CRYOPRESERVED VALVED ALLOGRAFTS, The American journal of cardiology, 80(3), 1997, pp. 358
This study shows that the broad anti-HLA antibody response against cry
opreserved valved allografts used for surgical repair of congenital he
art disease persists beyond 1 year after implantation. In 3 patients,
there were clearly defined HLA antibody specificities consistent with
the HLA phenotypes of the patients, i.e., the panel-reactive antibody
was directed against major alloantigen groups that were not expressed
by the antibody responders.
