Association between genetic polymorphisms and angiotensin-converting enzyme inhibitor-induced cough: a systematic review and meta-analysis

Abstract

Aim: Genetic polymorphisms may influence the incidence of angiotensin-converting enzyme (ACE) inhibitor-induced cough. This study aims to investigate this association. Methods: Ten electronic databases and PharmGKB were systematically searched. Pooled odds ratio values and their 95% CI were used to assess the association, using the random-effects model. Results: A total of 26 studies were included in the review, 17 of them were included from two separated meta-analysis (ACE I/D or BDKRB2-58T/C). Significant association was found between ACE I/D I carriers (ACE gene insertion) and ACE inhibitor-induced cough, showing racial and age differences. Conclusion: This study demonstrated that ACE I/D but not BDKRB2-58T/C polymorphism could be a predictor for the risk of ACE inhibitor-induced cough, especially in east Asians and the aged.
