Abstract
Aims of this studyAims of this study were to identify class I and class II antibodies in highly sensitized patients by flow cytometry single antigen bead (FC-SAB) assay and to evaluate according to donor HLA type in order to increase their kidney transplantation chance.Material and methodsWe analyzed 60 hypersensitive patients of 351 individuals, who applied to our laboratory for PRA test in November 2013-December 2014. Flow cytometric PRA screening and single antigen bead commercial kits were used for these analyses.ResultsIn our study group, 19 (31.7%) of these patients were male while 41 (68.3%) patients were female. The most common acceptable antigens were A*02 (10.11%), HLA-A*23 (10.11%), HLA-B*38 (8.79%) and HLA-DRB1*03 (7.83%) in hypersensitive patients. The highest antibody reactivity on SAB was observed against HLA-A*25, HLA-B*45, HLA-DRB1*04 and HLA-DRB1*08 antigens.ConclusionsThe determination of these acceptable and unacceptable antigens may increase their transplantation chance. Pre-transplant HLA antibody identifications provide prognostic information with respect to the determination of patients who are at increased risk of graft loss.
