Lipid lowering efficacy and safety of Ezetimibe combined with rosuvastatin compared with titrating rosuvastatin monotherapy in HIV-positive patients Saeedi, Ramesh; Johns, Kevin; Frohlich, Jiri; Bennett, Matthew T; Bondy, Gregory

Abstract

Background: HIV-infected patients on antiretroviral therapy frequently develop dyslipidemias and, despite therapy with potent lipid-lowering agents, a high percentage does not achieve guideline recommended lipid targets. In this study, we examined the efficacy of combination treatment with a statin and the cholesterol transport blocker, ezetimibe, vs. monotherapy with a statin in HIV-infected patients not achieving lipid goals. Methods: This was a 12-week, prospective, randomized, open-label clinical trial. Patients were eligible if they had an apolipoprotein B (apoB) >0.80 g/L despite therapy with rosuvastatin 10 mg daily for a minimum of 12 weeks. Patients were randomized to take ezetimibe 10 mg/rosuvastatin 10 mg or rosuvastatin 20 mg for 12 weeks. Percentage and absolute change in apoB (primary outcome), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, apoliporpotein A1 (apoA1), apoB/apoA1, TC/HDL-C, atherogenic index of plasma (API), and high-sensitivity C-reactive protein (hsCRP) were compared. Changes in safety parameters (such as AST, ALT, CK) and clinical symptoms were also assessed. Results: Forty-three patients (23 on ezetimibe 10 mg/rosuvastatin 10 mg and 20 on rosuvastatin 20 mg) completed the trial. Baseline characteristics did not differ between the groups. Significant improvements in apoB were seen with both ezetimibe plus rosuvastatin (mean of -0.17 g/L, p
