PG - 1031 LID - 10.3389/fphys.2017.01031 [doi] LID - 1031 AB - Background and Objective: Apolipoprotein E (APOE) plays important roles in lipoprotein metabolism and cardiovascular disease. Evidence suggests the APOE gene epsilon2/epsilon3/epsilon4 (epsilon2/epsilon3/epsilon4) polymorphisms might be associated with the susceptibility of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM). However, no clear consensus has yet been established. Therefore, the aim of this meta-analysis is to provide a precise conclusion on the potential association between APOE epsilon2/epsilon3/epsilon4 polymorphisms and the risk of CAD in patients with T2DM based on case-control studies. Methods: Pubmed, Embase, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases were searched for all relevant studies prior to August 2017 in English and Chinese language. The pooled odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were used to assess the strength of the relationships. The between-study heterogeneity was evaluated by Cochran's Q-test and the I(2) index to adopt fixed- or random- effect models. Results: A total of 13 studies were eligible for inclusion. There was evidence for significant associations between APOE epsilon4 mutation and the risk of CAD in patients with T2DM (for epsilon3/epsilon4 vs. epsilon3/epsilon3: OR = 1.69, 95% CI = 1.38-2.08, P < 0.001; for epsilon4/epsilon4 vs. epsilon3/epsilon3: OR = 2.72, 95% CI = 1.61-4.60, P < 0.001; for epsilon4/epsilon4+epsilon3/epsilon4 vs. epsilon3/epsilon3: OR = 1.83, 95% CI = 1.52-2.22, P < 0.001; for epsilon4 allele vs. epsilon3 allele: OR = 1.64, 95% CI = 1.40-1.94, P < 0.001). In contrast, no significant associations were found in genetic model of APOE epsilon2 mutation (for epsilon2/epsilon2 vs. epsilon3/epsilon3: OR = 1.67, 95% CI = 0.90-3.09, P = 0.104; for epsilon2/epsilon3 vs. epsilon3/epsilon3: OR = 1.18, 95% CI = 0.93-1.51, P = 0.175; for epsilon2/epsilon2+epsilon2/epsilon3 vs. epsilon3/epsilon3: OR = 1.26, 95% CI = 0.88-1.82, P = 0.212; for epsilon2 allele vs. epsilon3 allele: OR = 1.34, 95% CI = 0.98-1.84, P = 0.07). Conclusions: The APOE gene epsilon4 mutation is associated with an increased risk of CAD in patients with T2DM, while the epsilon2 variation has null association with this disease.
