Introduction: New-onset diabetes mellitus after transplantation (NODAT) is a common complication of organ transplantation, leading to allograft dysfunction. Genetic alterations of inflammatory cytokines have been reported to be associated with glucose homeostasis and diabetes.

Objectives: This study evaluated the rs763780 polymorphism of IL-17F gene in transplant recipients with and without NODAT.

Patients and Methods: The present retrospective study was conducted on ninety-one patients who have had a kidney transplant for at least three months. Patients were divided into two subgroups; recipients with NODAT (n=32) and kidney recipients without NODAT (n=59). After DNA extraction from patients’ blood samples, amplification and evaluation of specific polymorphism of the gene were performed using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Clinical and demographic data of patients were collected.

Results: The NODAT was detected in 81.3% (n=26) of TT genotype carriers, 12.5% of TC genotype carriers and 6.3% of CC genotype carriers. No statistically significant differences between the studied groups in the frequency of C and T alleles and the distribution of the abovementioned genotypes were detected (P≥0.721). In the NODAT group, graft rejection and age of patients were higher significantly (P≤0.017).

Conclusion: No significant correlation between the incidence of diabetes and rs763780 polymorphism of IL-17F gene was observed.

Implication for health policy/practice/research/medical education:

Dysfunction of pancreatic β-cells, insulin resistance, oxidative stress and low-grade chronic inflammation play important roles in the development of new-onset diabetes mellitus after transplantation (NODAT) among kidney transplant recipients. IL-17 polymorphisms impact on the pathogenesis of NODAT and variations in IL-17R is connected with type 1 diabetes (T1D) that are reported to be associated with the pathogenesis of NODAT.
