Dyslipidemia in HIV-positive patients: A randomized, controlled, prospective study on ezetimibe+fenofibrate versus pravastatin monotherapy

Abstract

Introduction: We designed a randomized, controlled prospective study aimed at comparing efficacy and tolerability of ezetimibe+ fenofibrate treatment versus pravastatin monotherapy in dyslipidemic HIV-positive (HIV+) patients treated with protease inhibitors (PIs). Methods: We consecutively enrolled 42 HIV+ dyslipidemic patients on stable PIs therapy (LDL cholesterol >130 mg/dl or triglycerides 200-500 mg/dl with non-HDL cholesterol >160 mg/dl). After basal evaluation, patients were randomized to a six-month treatment with ezetimibe 10 mg/day+fenofibrate 200 mg/day or with pravastatin 40 mg/day. Both at the basal evaluation and after the six-month treatment, the patients underwent blood tests for lipid parameters, and muscle and liver enzymes. Results: At baseline, the two groups (21 patients each) were similar with regards to gender, age, BMI, blood pressure and virologic and metabolic parameters. After the six-month therapy, total cholesterol, LDL cholesterol and non-HDL cholesterol decreased significantly (p <0.01) in both groups. high-density lipoprotein (HDL) cholesterol increased (44±10 to 53±12 mg/dl, p <0.005) and triglycerides decreased (from 265±118 mg/dl to 149±37 mg/dl, p <0.001) in the ezetimibe+fenofibrate group, whereas both parameters remained unchanged in the pravastatin group. Mean values of creatine kinase (CK), alanine aminotransferase and aspartate aminotransferase were unchanged in both groups; only one patient in the pravastatin group stopped the treatment after two months, due to increased CK. Conclusions: In dyslipidemic HIV+ patients on PI therapy, the association of ezetimibe+fenofibrate is more effective than pravastatin monotherapy in improving lipid profile and is also well tolerated. © 2014 Grandi AM et al; licensee International AIDS Society.
