Association of IL1 beta gene polymorphism and allograft functions in renal transplant recipients :a case control study from Kashmir Valley

BMC Nephrol. 2017 Mar 30;18(1):111. doi: 10.1186/s12882-017-0526-5.

Abstract

Background: Cytokines have been found to be the important mediators during renal graft outcome. Therefore, we designed this study to investigate the role of recipients' IL-1 β promoter (-511) and IL-1 β exon-5 (+3954) polymorphisms with the risk of graft outcome.

Methodology: We enrolled one hundred recipients of living-related renal transplants together with the age and sex matched controls from the healthy population not having any renal abnormality for this study. Genotype frequencies of the IL-1 β promoter (-511) and IL-1 β exon-5 (+3954) were analyzed using PCR-RFLP technique.

Results: Our results revealed significant differences in the healthy control group and patient group in IL 1β +3954 (p < 0.001). The frequency of variant type TT genotype was higher in RE group as compared to SGF and showed 4 fold risk of rejection (OR = 4.54, p < 0.069) although p value was not significant. The frequency of wild type CC genotype and CT was not significant (p value 0.89 and 0.74 respectively).

Conclusion: Our findings suggest that there is a prevalence of mutated allele of IL-1 gene cluster in our population, which may be responsible for renal dysfunction.
