Abstract
BACKGROUND
Cytokines are key mediators of the immune response after transplantation. The interleukin (IL)-2 cytokine family, which includes IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21, is of particular interest because of its importance in the allogenic response. The aim of this study was to examine the association between the rs6822844 gene polymorphism in the IL2-IL21 region and allograft function after kidney transplantation.
METHODS
The study enrolled 270 Caucasian kidney allograft recipients (166 males and 104 females, mean age 47.63 ± 12.96 years). Following parameters were recorded in each case: recipient's age, delayed graft function (DGF), occurrence and number of episodes of acute rejection (AR), and chronic allograft dysfunction (CAD). Genotyping of the rs6822844 IL2-IL21 cluster gene polymorphism was performed using real-time PCR assay.
RESULTS
There were no statistically significant differences in the genotypes and alleles of the rs6822844 IL2-IL21 cluster gene polymorphism among patients with DGF (p = 0.72), AR (p = 0.69) and CAD (p = 0.77), or in creatinine concentrations 1, 3, 6, 12, 24 or 36 months after transplantation (p = 0.46, p = 0.58, p = 0.6, p = 0.72, p = 0.7, p = 0.76, respectively).
CONCLUSION
It seems that the rs6822844 IL2-IL21 gene cluster polymorphism is of little importance in allograft function after kidney transplantation.
