Human leukocyte antigen variation among Iranian renal transplant recipients.
BACKGROUND
HLA typing analysis is important in renal transplant patients.


OBJECTIVE
We made a plan to determine the most frequent HLA antigens in Iranian kidney transplant patients.


METHODS
In a retrospective cross sectional study, HLA patterns were defined in 512 kidney transplant recipients (67% male and 33% female) from different transplant centers of Tehran, Iran between 2008 and 2011 by microcytotoxicity assay.


RESULTS
The studies samples were of different ethnic groups of the Iranian kidney transplants. Considerable variations were observed in each HLA sub class. A2, A1, A3, A24 and A26 were the most frequent HLA-A antigens. Among HLA-B, the predominant antigens were B35; B13, B15, B13 and B18. The most frequent HLA-DR antigens were DR 4, DR11, DR1, DR3 and DR15. DQ1 showed the highest frequency and followed by DQ3 and DQ2.


CONCLUSIONS
These results showed considerable heterogeneity in both HLA class I and class II antigens, which reflects recent admixture of this group with neighboring Middle East populations.
