The aim of this study was to determine HLA associations with progression to end-stage renal disease (ESRD) in the mixed Zulian population in Venezuela, regardless of other factors. A retrospective study to determine HLA Class I association was performed on 188 patients with ESRD due to different types of glomerulonephritis, and 202 healthy controls. Patients and control groups were serologically typed by Terasaki microlymphocytotoxicity technique using commercial Class I plates including 26 HLA-A and 48 HLA-B specificities. The antigens positively associated to the ESRD were: HLA-B38, B51, B53 and B62. Negatively associated antigens were: HLA-A9, B12, B17, B40 and B48. The haplotypes positively associated were: HLA-A2-B51, A2-B53, A23-B38 and A68-B38. The negatively associated haplotypes were: HLA-A2-B12, A2-B48, A9-B35 and A28-B40. The high Odds ratio observed and its statistical corroboration reflect the strength of the described association between HLA antigens and ESRD. Further molecular studies should clarify types and subtypes of the HLA class I alleles involved in the progression to ESRD. |
