Hyperlipidemia in HIV-positive patients receiving antiretrovirals

OBJECTIVE: To assess the frequency of lipid abnormalities and treatment outcomes for hyperlipidemia in HIV-positive patients receiving antiretroviral (ARV) therapy as outpatients at a Veterans Affairs HIV clinic. METHODS: All patients monitored for at least 3 months were reviewed. Data collected included age, most recent CD4+ cell count and viral load, ARV history, and all fasting cholesterol, triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) values. The ARV therapy at the time of lipid readings was classified as including protease inhibitors (PI+) or not including them (PI-). Lipid values were compared with goals per national guidelines and risk factors. RESULTS: Male patients (n = 101) providing 210 lipid profiles were evaluated (median 2 per patient). Median age was 51 years. Fourteen patients were diabetic, 31 were hypertensive, and 6 patients had documented coronary disease. Mean cholesterol, triglycerides, and LDL values were significantly higher in PI+ (n = 50) compared with those of PI- patients (n = 51; p < 0.05). HDL values were not different between groups. Significantly more PI+ patients had lipid concentrations above recommended goals compared with PI- patients (17 vs. 7; p = 0.04). Six patients achieved lipid goals after following a low-fat diet (4 PI+). Fifteen subjects (11 PI+) were being treated with medications. Ten patients (67%) reached lipid goals, 2 had not reached goals (13%), and 3 (20%) were undergoing medication titration. CONCLUSIONS: Our HIV-infected patients had significantly higher cholesterol, triglyceride, and LDL values when PI+. In contrast to other reports, the majority of patients treated for lipid abnormalities achieved treatment goals.
