Atherogenic lipid profile and cardiovascular risk factors in HIV-infected patients (Nétar Study)

Abstract

We undertook a transverse study of 603 HIV outpatients to determine their atherogenic lipid profile (ALP) and cardiovascular risk (CVR) factors. CVR was estimated from the Framingham score. ALP was defined as a total cholesterol to high density lipoprotein (HDL)-cholesterol ratio > or =5 plus triglycerides > or =150 mg/dL and a CVR >10% at 10 years was considered high. The most frequent CVR factor was smoking. ALP was diagnosed in 26.9% and was related to sex (odds ratio [OR] 2.6; 95% confidence interval [CI], 1.3-5.0; P = 0.0047), protease inhibitor use (OR 3.8; 95% CI, 1.8-7.8; P = 0.0002) and sexual HIV risk (OR 2.4; 95% CI, 1.4-4.0; P = 0.0004). The mean 10-year CVR was 6.2%, was high in 20.4% and was related to sexual HIV-risk (OR 3.8; 95% CI, 2.1-6.8; P < 0.00001) and nadir cell differentiation factor (CD4) (OR 1.0; 95% CI, 1.0-1.003; P = 0.0026). Although the current CVR of our patients is not high, the contribution to the lipid profile of highly active antiretroviral therapy (HAART)-associated factors and the high prevalence of some risk factors may lead to an increased future CVR.
