Abstract: Objective To analyze the relationship of polymorphisms of glutamate cysteine ligase modifier (GCLM) subunit, glutamate cysteine ligase catalytic (GCLC) subunit and glutathione S transferase P1 (GSTP1) with acute anti-tuberculosis drug-induced liver injury (AADILI).Methods In our study, 92 cases with AADILI were enrolled as the study group and 86 cases without AADILI were enrolled as the control group. T-588C loci of GCLM gene, C-129T loci of GCLC gene and Ile105Val loci of GSTP1 gene were detected using polymerase chain reaction restriction fragment length polymorphism. Representativeness of genotype frequencies were verified using Hardy-Weinberg equilibrium. Factors related to the occurrence of AADILI were analyzed using Logistic method.Results There were single nucleotide polymorphisms (SNPs) at T-588C loci of GCLM gene, C-129T loci of GCLC gene and Ile105Val loci of GSTP1 gene, which were stable and in accordance with Hardy-Weinberg equilibrium. There were significant differences in genotype distributions of TT at GCLM T-588C loci, CC at GCLC C-129T loci and GG at GSTP1 Ile105Val loci between the 2 groups (P< 0.05). Genotypes of TT at GCLM T-588C loci, CC at GCLC C-129T loci and GG at GSTP1 Ile105Val loci were risk factors for AADILI.Conclusion The SNPs of GCLM T-588C, GCLC C-129T and GSTP1 Ile105Val genes are associated with AADILI susceptibility. TT at GCLM T-588C loci, CC at GCLC C-129T loci and GG at GSTP1 Ile105Val loci can increase the risk of AADILI.
