[Anti-HLA antibodies in nephropathic patients].

Background: The presence of anti-human leukocyte antigen (HLA) alloantibodies in nephropathic patients is due to immunogenic stimuli such as transfusions, pregnancies, and transplantations. These stimuli can be highlighted using a classic aspecific serologic technique, such as complement-dependent cytotoxicity (CDC) or using more recent and specific techniques, such as cytofluorimetrics or enzyme linked immunoabsorbant assay (ELISA). Because the presence of anti-HLA preformed antibodies is linked to the largest incidence of both acute and chronic rejection, it seems appropriate to re-evaluate that data obtained using aspecific classic serological analysis techniques by using the more specific cytofluorimetric technique.
