title: Angiotensin-converting enzyme insertion/deletion polymorphism and susceptibility to allergic rhinitis in Chinese populations: a systematic review and meta-analysis.
abstract: In view of the controversies surrounding the angiotensin-converting enzyme (ACE)-allergic rhinitis (AR) association, a systematic review and meta-analysis of the ACE genetic association studies of AR was performed in Chinese populations. PubMed, Springer Link, OvidSP, Chinese biomedical database, Chinese national knowledge infrastructure, Chinese VIP and Wanfang databases were searched for related studies. A total of 4 studies including 415 AR patients and 309 controls were involved in this meta-analysis. Overall, significant association was found between ACE I/D polymorphism and AR risk when all studies in Chinese populations pooled into the meta-analysis (allele, OR 1.50, 95 % CI 1.19-1.90; homozygous, OR 2.59, 95 % CI 1.52-4.41, recessive, OR 2.05, 95 % CI 1.27-3.32). In the subgroup analysis by ethnicity, ACE I/D polymorphism was associated with significant elevated risks of AR in Chinese Han under homozygous and recessive models (homozygous, OR 4.36, 95 % CI 1.76-10.82, recessive, OR 2.51, 95 % CI 1.18-5.34). In conclusion, this meta-analysis provides the evidence that ACE I/D polymorphism may contribute to the AR development in Chinese populations and studies with large sample size and wider spectrum of population are warranted to verify this finding.
