Popis: | Tuberculosis (TB) is still a major health concern and side-effects related to the treatment, especially drug-induced hepatotoxicity (DIH), should be better investigated. In the present study, a possible association between anti-TB DIH and cigarette smoking, N-acetyltransferase 2 (NAT2), Cytochrome P450 2E1 (CYP2E1) and Cytochrome P450 3A4 (CYP3A4) genotypes was studied in 131 TB Brazilian patients. The NAT2 and CYP3A4 genetic polymorphisms were determined using a polymerase chain reaction (PCR) direct sequencing approach and genetic polymorphisms of CYP2E1 gene were determined by restriction fragment length polymorphism (RFLP). The risk of anti-TB DIH was lower in rapid/intermediate acetylators when compared to slow acetylators (OR: 0.34, CI 95: 0.16-0.71; p 0.01). A decreased risk of developing anti-TB DIH was also observed in active smokers when compared to non-smokers (OR: 0.28, 95 CI: 0.11-0.64; p 0.01). Significant association between CYP3A4 genotypes and hepatotoxicity was not observed, as well as between CYP2E1 genotype and hepatotoxicity, whose frequency of patients with wild homozygous was more prevalent. The anti-TB drugs interactions with smoking on hepatotoxicity, as well as the NAT2 phenotype, may require to adjust therapeutic regimen dosages or alarm in case of adverse event developments. |
