The relationship between ApoE gene polymorphism and the efficacy of statins controlling hyperlipidemia.

ABSTRACT:

Objective

To explore the relationship between ApoE gene polymorphism and clinical efficacy of statins on lipidemia.

Methods

Peripheral venous blood was obtained from 220 patients with hyperlipidemia who were admitted to the outpatient department of our hospital. The potential relationship between ApoE gene polymorphism and clinical effect of statins was analyzed.

Results

In the three isomers (E2, E3, E4) of ApoE, expression level of ApoE protein in ApoE4 gene carriers was significantly different from that in E2 or E3 gene carriers (both P<0.05). At the same time, both the decrease rate of total cholesterol (TC) in blood lipid and low density lipoprotein cholesterol (LDL-C) and the rise rate of high density lipoprotein cholesterol (HDL-C) in ApoE4 carriers after taking statins were much lower than those in non-ApoE4 patients (P<0.05).

Conclusion

ApoE gene polymorphism is associated with hyperlipidemia and has certain influence on the clinical efficacy of statins in treatment of hyperlipidemia.

Project description:BackgroundThe relationship between the APOE gene polymorphism and lipid profiles and atrial fibrillation (AF) remains controversial. The current study purposed to investigate how the APOE gene SNPs (rs429358 and rs7412) and lipid profile are associated with the risk for AF among the Hakka population in southern China.MethodsFinally, 1367 patients were enrolled in this study, including 706 participants with AF (41 ~ 98 years old, 58.64 % male) and 661 non-AF subjects (28 ~ 95 years old, 59.46 % male). The collected data included baseline characteristics, medical history, laboratory tests and echocardiography parameters. A general linear model (two-way analysis of variance (ANOVA)) and Tukey post-hoc tests were applied to identify an APOE allele, AF group, and interaction effect on lipid profiles. Logistic regression analysis was performed to identify risk factors for AF.ResultsFor AF group, the most common genotype was E3/E3 (53.82 %), followed by E3/E4 (28.19 %), E2/E3 (13.60 %), E4/E4 (1.98 %), E2/E4 (1.84 %) and E2/E2 (0.57 %). The two-way ANOVA followed by the Tukey procedure showed the following: the lipid levels depended significantly on AF and APOE allele groups for TG, TC, LDL-C and Apo-B (all P < 0.001), and statistically significant interactions between AF and APOE allele were observed in the above 4 variables (all P < 0.05). Multivariate regression analysis indicated that age ≥ 65years (P < 0.001), high diastolic blood pressure (DBP ≥ 90mm Hg, P = 0.018), a high levels of total cholesterol (TC ≥ 5.2mmol/L, P < 0.001) and triglyceride (TG ≥ 1.7mmol/L, P = 0.028), but not the two SNPs of the APOE gene (rs7412 and rs429358) (OR 1.079, P = 0.683), were significant independent risk factors for AF in the study population.ConclusionsThe principal findings of this study showed that individuals at high risk for AF were those over 65 years of age, higher DBP as well as high levels of TC and TG among the southern China Hakka population. The levels of TG, TC, LDL-C and Apo-B depended significantly on AF and APOE allele groups, and statistically significant interactions between AF and APOE allele were observed in the above 4 variables, although the APOE gene SNPs (rs429358 and rs7412) were no significant risk for AF incidence. Further investigation is needed to elucidate whether other SNPs of the APOE gene have a bearing on AF incidents.
