Introduction: Oxidative stress contributes to delayed graft function (DGF). Glutathione S-transferases (GSTs) are polymorphic genes which produce enzymes with protective effect against oxidative stress. This study aimed to investigate the association between donors' and recipients' GSTM1 and GSTT1 polymorphisms and DGF, creatinine clearance, and oxidative stress parameters in kidney allograft recipients.

Materials And Methods: One hundred and eighty-two donor-recipient pairs were studied. Lipid peroxidation and total antioxidant capacity were measured in the recipients' plasma as the parameters of oxidative stress. Delayed graft function was determined based on at least 10% increase, no change, or less than 10% decrease in the serum creatinine level in 3 consecutive days during the 1st week after transplantation.

Results: Lipid peroxidation was significantly greater in the recipients with DGF (P < .001). The frequency of GSTM1 null was significantly higher in the patients with DGF (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.17 to 0.86; P = .02). There was also a significant association between the donors' GSTM1 polymorphism and DGF (OR, 0.31; 95% CI, 0.14 to 0.68; P = .003). A significant association was detected between combination of recipients and donors' GSTM1 polymorphism and DGF (OR, 0.20; 95% CI, 0.07 to 0.64, P = .006). The recipients' GSTM1 polymorphism, alone and in combination with donors' GSTM1 and GSTT1, significantly affected the creatinine clearance on discharge day.

Conclusions: These results suggest that the donors and recipients' GSTM1 polymorphism may be a major risk factor for oxidative stress and poor kidney allograft transplantation outcomes.

Effect of donor tumor necrosis factor-alpha and interleukin-10 genotypes on delayed graft function and acute rejection in kidney transplantation.

Iran J Kidney Dis 2013 Mar;7(2):135-41

Introduction: This study evaluated the influence of interleukin-10 (IL10) gene -1082G>A and tumor necrosis factor-alpha (TNF) gene -308G>A polymorphisms in the donor and recipients on the acute rejection (AR) episodes and delayed graft function (DGF) in kidney transplant recipients.

Materials And Methods: The IL10 -1082G>A and TNF -308G>A polymorphisms were determined in 100 kidney allograft recipients and their donors using the polymerase chain reaction-amplification refractory mutation system polymerase chain reaction-restriction fragment length polymorphism methods. Transplantation outcomes were determined in terms of AR and DGF criteria.

Results: The A allele of the TNF polymorphism (high producer) in the donors was associated with DGF in the recipients (odd ratio, 3.1; 95% confidence interval, 1.2 to 8.1). There was also a significant association between the combination of donor's IL10-TNF genotypes and DGF (odd ratio, 4.8; 95% confidence interval, 1.4 to 17.1); the frequency of a combination of IL10 AA or GA and TNF AA or GA was higher in the recipients with DGF. No association was found between the donors and recipients' IL10 -1082G>A and TNF -308G>A polymorphisms and AR. No association was detected between recipients and donors' IL10 polymorphisms or recipients' TNF polymorphisms and DGF.

Conclusions: This study showed that donors with high TNF production may have increased risk of DGF in their recipients. Routine screening of these gene polymorphisms may have a clinical role in identifying patients at risk of DGF.
