Abstract

Objective: Apolipoprotein E (APOE) plays an important role in the lipid metabolism. polymorphisms have been implicated in susceptibility to diabetes mellitus (DM). However, the association between polymorphisms and the risk of DM among the hypertensive patients remains unclear. Our study aimed to evaluate this relationship to provide clues for further developing DM in hypertensive patients.

Methods: The study included 808 hypertensive patients with DM and 1226 hypertensive patients without DM as controls. The 388T>C (rs429358) and 526C>T (rs7412) polymorphisms were genotyped by polymerase chain reaction (PCR) - microarray. Differences in genotypes between subjects and controls were compared. To analyze the relationship between genotypes and DM risk, multiple logistic regression analysis was performed after adjusting for gender, age, smoking history, and drinking history.

Results: The E2/E4, E3/E3 genotype and ε2, ε3 allele frequency had significant difference between DM patients and controls (<0.05). The DM patients with ɛ4 allele had lower level in high-density lipoprotein cholesterol (HDL-C) and higher level in apolipoprotein B (ApoB) than those with ɛ2 allele. The results of logistic regression analysis indicated that the genotype of E2/E3 with adjusted OR=1.350 (95% Cl=1.009-1.806, =0.043) and E3/E4 with adjusted OR=1.325 (95% Cl=1.034-1699, =0.026) may be independent risk factors for DM.

Conclusion: E2/E3 and E3/E4 genotypes may be risk factors for developing diabetes mellitus in hypertensive patients.
