ABSTRACT
Pre- and post-renal transplantation panel reactive antibody (PRA) screening is associated with increased incidence of hyperacute or acute graft rejection and graft loss. This study was designed to find any relationship PRA sensitization and associated human leukocyte antigen (HLA)-specific antibodies in Turkish renal transplant candidates. We included 340 patients who were in the renal transplantation waiting list in the study. We determined PRA sensitization ratio and the associated anti-HLA IgG antibody distribution of the patient group. The PRA testing was currently performed and levels above 30% were accepted to be positive. The PRA class I positivity was determined in 24 (7%) and class II in 34 (10%) of the patients. The most frequent HLA antibodies for class I were B56, A2, A34, A1, A23, A24 and B61; and for class II were DR11, DR14, DQ7, DR10, DQ5, DR1 and DR7, respectively. From these, the increase of the numbers of anti-HLA class II antibodies was significantly correlated with the increase of PRA sensitization ratio. In conclusion, the identification of the associated HLA-specific antibodies and correlation with the Turkish population HLA antigen distribution will identify the high-risk patients who are candidates for transplantation.
