Antiretroviral Therapy in HIV-Positive Women Is Associated With Increased Apolipoproteins and Total Cholesterol

OBJECTIVES: Dyslipidemia has become a common problem in HIV disease, especially in patients on combination antiretroviral (ARV) therapy. However, little data are available to evaluate lipid abnormalities in women on ARV therapy. METHODS: Using a cross-sectional design, the prevalence of abnormal plasma lipid and lipoprotein concentrations as well as other biomarkers for vascular disease was determined in 184 HIV-positive women from 2 HIV clinics in Atlanta during 2002. RESULTS: Most of the women were African American (89%), with median age of 41 years (range 21-72); 6% were diabetic, 44% smoked, and 67% were overweight. ARV therapy defined the comparison groups that included treatment with a protease inhibitor (PI)-based regimen for more than 3 months in 76 (41%), treatment with a nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimen for more than 3 months in 38 (20%), and no ARV therapy for the past 3 months in 70 (38%). Women being treated with a PI or NNRTI had higher total cholesterol and triglyceride levels than patients on no therapy (P < 0.05 for each). Women treated with either PIs or NNRTIs had significantly higher apolipoprotein B and apolipoprotein C-III levels than patients on no therapy (P < 0.01 for each). CONCLUSIONS: In this cross-sectional study of HIV-infected women, either PI or NNRTI therapy elevated levels of total cholesterol and specific apolipoproteins. These findings, on a background of an older population with additional risk factors of smoking, obesity, and diabetes, may lead to future atherosclerotic events in these patients.
