Abstract
AIMS: To determine whether polymorphisms of the genes encoding donor or recipient interleukin 1alpha (IL-1alpha), tumour necrosis factor alpha (TNFalpha), or IL-4 have any impact on the incidence of acute rejection after renal transplantation. METHODS: All donors and recipients were genotyped for three polymorphisms in the three cytokine genes: IL1A -889, TNFA -308, and IL4 -590. RESULTS: Statistical analysis of the data obtained revealed no association between the cytokine gene polymorphisms tested and the incidence of post-transplant acute rejection. After stratification for human leucocyte antigen (HLA) matching, it was found that kidneys from donors positive for the TNFA-A allele had a significantly increased incidence of acute rejection in HLA-DR mismatched transplants. CONCLUSIONS: This finding argues for prospective TNFA genotyping of renal donors, with avoidance of allocation of kidneys from donors positive for the TNFA-A allele to HLA-DR mismatched recipients.
