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.
