BACKGROUND: Apolipoprotein-E (ApoE) gene polymorphism has an important role in lipoprotein metabolism and could participate in the development of cardiovascular diseases (CVD). Plasminogen activator inhibitor-1 (PAI-1) is also regarded as a risk factor for CVD. The aim of the present study is to further investigate the possible link(s) between ApoE gene polymorphism and plasma PAI-1 antigen and serum lipid profile in peritoneal dialysis (PD) and hemodialysis (HD) patients. MATERIAL AND METHODS: We studied 72 PD patients (38 female, mean age 49.9 +/- 16.1 years), 72 HD patients (22 female, mean age 57.4 +/- 14.6 years), and 42 healthy subjects (21 female, mean age 50.1 +/- 18.6 years). Serum lipid parameters, plasma PAI-1 levels, and ApoE genotypes were determined in all subjects. RESULTS: The distribution of ApoE genotypes and alleles frequencies was similar in dialysis patients and healthy controls. In PD patients, total cholesterol (TC), low-density lipoprotein (LDL)-C, and ApoB levels were significantly higher than that of HD patients. HD patients with E3/4 genotype had elevated TC, LDL-C and ApoB levels compared with E3/3 genotype. TC and triglyceride levels were also higher in E3/4 genotype than that of E2/3 genotype. PD and HD patients showed a significantly increased PAI-1 levels compared with controls, whereas PAI-1 levels were highest in HD patients. There was no significant relation between ApoE genotypes and PAI-1 levels. CONCLUSIONS: The present study suggests that ApoE polymorphism significantly affects serum lipid profile in HD patients and epsilon4 allele carriers are more susceptible to have atherogenic lipid profile.
