Effect of CD14 polymorphisms on the risk of cardiovascular disease: evidence from a meta-analysis

Abstract

Abstract Background CD14 polymorphisms are associated with an increased risk of cardiovascular events. So far, many studies have been conducted, whereas the results were not always consistent. Materials and methods Twenty-six articles involving thirty-seven datasets were recruited to evaluate the association between rs2569190 (9413 patients and 7337 controls), C-159T (4813 patients and 2852 controls) polymorphisms and cardiovascular diseases in a meta-analysis. The random or fixed effect models were used to evaluate the pooled odds ratios (ORs) and their corresponding 95% confidence intervals. Results The strongest association was observed between rs2569190 and CVD in overall population (T vs. C, OR = 1.169, 95% CI: 1.087–1.257, p = 2.44 × 10− 5). Analysis after stratification by ethnicity indicated that rs2569190 was related to CVD in East Asian population (T vs. C, OR = 1.370, 95% CI; 1.226–1.531, p = 2.86 × 10− 8) and a potential relationship in European (T vs. C, OR = 1.100, 95% CI: 1.019–1.189, p = 0.015). In the stratification of endpoints, the associations were found in CHD subgroup (T vs. C, OR = 1.357, 95% CI: 1.157–1.592, p = 2.47 × 10− 7) and in AMI subgroup (T vs. C, OR = 1.152, 95% CI: 1.036–1.281, p = 0.009). However, we did not find any association between C-159T polymorphism with cardiovascular disease under any model. Conclusions The SNP rs2569190 significantly contribute to susceptibility and development of cardiovascular disease, particularly in the East Asian population and in the subtype CHD group, in addition, a potential association was observed in the AMI group, T allele acts as a risk factor for cardiovascular disease.
