Abstract:
Objective To investigate the association of genetic polymorphisms in glutathione S-transferases T1 (GSTrl), M1 (GSTM1) and P1 (GSTP1) with aristolochic acid nephropathy (AAN) of Chinese people in Wenzhou of China. Methods Fifty-nine patientswith AAN (AAN group) including 29 male and 30 female as well as 157 healthy ethnically matched controls (control group) including 93 male and 64 female were enrolled in this study. The genotypes of GSTT1, GSTMI and GSTP1 were determined by multiple PCR and confronting two-pair primers PCR (CTPP-PCR). Results The genotype frequencies of GSTP1 were in Hardy-Weinberg equilibrium. Compared with the healthy controls, the frequency of GSTT1 null genotype was significantly higher in the patients with AAN (66.1% vs 48.4%,P＜0.05). Risk of A.AN for individuals with GSTT1 null genotype was 1.747 fold of those without GSTIl null genotype (95% CI=0.818-3.731). The frequency of GSTM1 null genotype, GSTP1 variant genotypes and GSTP1 G allele in the patients and in the controls were 40.7%, 28.8%, 16.1% and 47.8%, 31.8%, 17.5%, respectively, which were not significantly different. No significant differences were found in prevalence of GSTM1 and GSTP1 gene distribution between patients and controls. Conclusion GSTrl gene polymorphism appears to be associated with susceptibility to AAN in Southern China.
