As the incidence of end-stage renal disease (ESRD) is rapidly increasing, the demand for dialysis and transplantation has dramatically increased, which has led to concerns about the availability and equitable allocation of kidneys for transplantation. The distribution of HLA-A, B and DR alleles in 148 renal transplant recipients and 191 live related prospective donors from 2009 to 2010 were analyzed. Allele frequencies and haplotype frequencies were calculated in recipients and donors. The prospective donors were further analyzed on the basis of their relationship to the patients and according to the sex ratio. A significant female preponderance was noted in the prospective donor population, most of whom were either siblings or parents of the recipients. On the contrary, the recipient population predominantly comprised of males. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in renal transplant patients were HLA-A*11, A*02, A*01, A*24; HLA-B*35, B*40, B*44, B*15, B*52, and HLA-DRB1*15, DRB1*07, DRB1*13, DRB1*11 respectively. The most frequent HLA-A, HLA-B, HLA-DRB1 alleles in prospective donors were HLA-A*02, A*11, A*33, A*24; HLA-B*35, B*44, B*40, B*15 and HLA-DRB1*15, DRB1*07, DRB1*11, DRB1*13 respectively. A*11-B*35, A*02-DRB1*15, B*40-DRB1*15 were the most common HLA A-B , HLA A-DR, HLA B-DR haplotypes respectively in renal transplant patients, whereas, A*11-B*35, A*11-DRB1*15, B*44-DRB1*07 were the most common haplotypes in renal donors. In three locus haplotype, HLA-A*02-B*40-DRB1*15 was the most frequent haplotype in patients, whereas, in prospective renal donors HLA-A*33-B*44-DRB1*07 was the most frequent haplotype. |
