Abstract
Chronic obstructive pulmonary disease (COPD) is a high incidence in the elderly and significantly affects the quality of life. CYP2C9 and CYP2C19 play an important role in tobacco-related diseases and inflammatory reactions. Thus, we aim to investigate the association between CYP2C9/CYP2C19 polymorphisms and the risk of COPD. In this study, a total of 821 subjects were recruited which include 313 COPD cases and 508 healthy controls. Seven SNPs of CYP2C9/CYP2C19 were selected for genotyping. The odds ratios (ORs) and 95% confidence interval (95% CI) were calculated using logistic regression analysis to evaluate the association between COPD risk and CYP2C9/CYP2C19 polymorphisms. Our study showed that A allele of rs9332220 in CYP2C9 was associated with reducing COPD risk (OR = 0.64, 95% CI = 0.43–0.94, p = 0.021). And rs111853758 G allele carrier could significantly decrease 0.35-fold COPD risk compared with T allele carrier (OR = 0.65, 95% CI = 0.45–0.96, p = 0.027). Furthermore, sex-based stratification analysis showed that rs9332220 and rs111853758 polymorphisms were associated with the risk of COPD in males. This is the first study to investigate the association between CYP2C9 and CYP2C19 genetic polymorphisms and COPD risk, which may give a new perspective on the prevention and diagnosis of COPD.
