A meta-analysis on the association between genetic polymorphisms of osteoprotegerin and cardiovascular disease / 中华心血管病杂志

ABSTRACT

Objective@#To explore the association between genetic polymorphisms of rs2073617T/C (950T/C) and rs2073618G/C(1181G/C) in the osteoprotegerin gene and cardiovascular disease with meta-analysis.@*Methods@#A computer-based search for the study of relationship between genetic polymorphisms of rs2073617T/C and rs2073618G/C in the osteoprotegerin gene and cardiovascular disease were performed in electronic databases including China National Knowledge Infrastructure(CNKI), China Biomedical Literature Database, Wanfang Database, Chinese Journal Full-text Database, Embase, PubMed, and Cochrane Library, supplemented by manual search, from the beginning of library to February 28, 2017. The quality of the included studies were assessed by the Newcastle-Ottawa Scale (NOS) scoring system. Data were analyzed using STATA 12.0 software.@*Results@#Eleven clinical case-control studies that enrolled 2 115 patients with cardiovascular disease and 1 467 healthy subjects were included.The results indicated that osteoprotegerin gene polymorphisms of rs2073617T/C and rs2073618G/C might be closely associated with the susceptibility to cardiovascular disease(rs2073617T/C allele model: OR=0.79, 95%CI 0.73-0.87, P=0.001;rs2073618G/C M allele and W allele: OR=0.83, 95%CI 0.74-0.92, P=0.001). The osteoprotegerin gene polymorphisms of rs2073617T/C and rs2073618G/C were significantly related to the incidence of coronary artery disease and acute coronary syndrome(coronary artery disease allele model: OR=0.83, 95%CI 0.75-0.92, P=0.001; acute coronary syndrome allele model: OR=0.73, 95%CI 0.62-0.85, P<0.001). However, there was no significant correlation between the genetic polymorphisms of these two sites and the lesion vessel number of coronary artery (rs2073617T/C allele model:OR=1.00, 95%CI 0.81-1.24, P=0.985;rs2073618G/C allele model:OR=0.98, 95%CI 0.80-1.21, P=0.626). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-ligase detection reaction(PCR-LDR) evidenced the association between osteoprotegerin gene polymorphisms and cardiovascular disease(allele model: OR=0.79, 95%CI 0.72-0.86, P<0.001), but no obvious relationship was found with fluorogenic quantitative detection and molecularprobe(allele model: OR=0.86, 95%CI 0.65-1.12, P=0.263).@*Conclusion@#This meta-analysis indicates that the osteoprotegerin gene polymorphisms of rs2073617T/C and rs2073618G/C may be closely related to the increased risk of cardiovascular disease.
