Abstract:

Objective: To investigate the correlation between SLC22A12 gene polymorphism and hyperuricemia induced by pyrazinamide in patients with pulmonary tuberculosis. Methods: A total of 514 patients with pulmonary tuberculosis who had received an intensive regimen containing pyrazinamide in the Third People’s Hospital of Kunming from January 2019 to March 2021 were collected. A total of 294 patients with hyperuricemia were selected as the elevated uric acid group and 220 patients without hyperuricemia were selected as the normal uric acid group. The SNP Sequenom MassARRAY genotyping was used to detect the polymorphisms of rs11602903, rs559946, rs475688 and rs476037 in SLC22A12 gene, and logistic regression model was used to analyze the correlation between the the polymorphisms of related loci and hyperuricemia induced by pyrazinamide. Results: After 4-week treatment with pyrazinamide, the serum uric acid in the elevated uric acid group ((648.32±109.23) μmol/L) was significantly higher than that in the normal uric acid group ((319.14±52.64) μmol/L), and the difference was statistically significant (t=-15.425,P=0.000). Logistic regression model was used to analyze the correlation between the genotypes and alleles of each locus and the occurrence of hyperuricemia in the elevated uric acid group and the normal uric acid group. The results showed that the rs475688 TC (50.3% (148/294) vs. 44.1% (97/220)), TT genotype (21.8% (64/294) vs. 6.4% (14/220)) and T allele (46.9% (276/588) vs. 28.4% (125/440)) of patients in the normal group had a significantly increased risk of hyperuricemia after taking pyrazinamide (OR (95%CI) were 2.028 (1.381-2.978), 6.077 (3.187-11.586), 2.229 (1.714-2.900)). The risk of hyperuricemia was significantly reduced in patients with TA (32.3% (95/294) vs. 50.0% (110/220)), TT genotype (4.1%(12/294) vs. 8.2% (18/220)) and T allele (20.2% (119/588) vs. 33.2% (146/440)) of rs11602903 and TC (32.7% (96/294) vs. 45.5% (100/220)), T allele (20.4% (120/588) vs. 26.4% (116/440)) of rs559946 (OR (95%CI) were 0.425 (0.293-0.616), 0.328 (0.152-0.710), 0.511 (0.385-0.678); 0.578 (0.401-0.833), 0.716 (0.535-0.959), respectively). Conclusion: The rs11602903 and rs559946 polymorphisms of SLC22A12 gene may be related to the reduction of pyrazinamide-induced hyperuricemia. The rs475688 polymorphism may increase the risk of pyrazinamide-induced hyperuricemia.
