Abstract:
AIM:To investigate the effects of glutathione-S-transferase(GST)gene polymorphism on the concentration of 6-thioguanine nucleotides(6-TGN),an active metabolite of azathioprine(AZA),in patients with inflammatory bowel disease(IBD),in order to provide reference for the optimization of AZA treatment in patients.METHODS:The clini-cal data of patients with IBD treated by AZA were collected prospectively,the genotypes of GST-A1,GST-M1,GST-P1 and GST-T1 were detected by tar-geted sequencing of multiplex PCR combined with high-throughput sequencing technology before ad-ministration,and the steady-state trough concen-trations of 6-TGN in patients' red blood cells were determined by HPLC.Statistical analysis was carried out by SPSS 26.0 software.RESULTS:A total of 90 patients were included in this study.The alleles fre-quencies of GST-A1,GST-M1,GST-P1 and GST-T1 were consistent with Hardy-Weinberg equilibrium law.Logistic regression analysis showed that carry-ing GST-A1 mutant gene was an independent risk factor for the increase of trough concentration of 6-TGN(low concentration OR=17.50,P=0.030;high concentration OR=3.60,P=0.033),while the gene polymorphism of GST-M1,GST-P1,GST-T1 had no significant correlation with the concentration of 6-TGN(P>0.05).CONCLUSION:The gene polymor-phism of GST-A1 may affect the concentration of 6-TGN,an active metabolite of AZA,and detection of GST-A1 genotype before AZA treatment will contrib-ute to clinical individualized medication.
