A prospective study on treatment of hypercholesterolemia with lovastatin in renal tranplant patients receiving cyclosporine

Abstract

Hypercholesterolemia occurs commonly in renal transplant recipients and may contribute to the high cardiovascular morbidity and mortality in these patients. Although an effective hypolipidemic agent, lovastatin has been associated with rhabdomyolysis and acute renal failure in patients on cyclosporin A (CsA). In this study, lovastatin was administered at 10 mg/day for 8 wk followed by 20 mg/day for 12 wk to six renal transplant recipients who were receiving CsA concomitantly. The 10-mg/day dose was effective, but an additional lipid-lowering effect was seen with the 20-mg/day dose. Both serum total cholesterol and low-density lipoprotein cholesterol levels decreased by 27% at the end of the 20 wk of lovastatin administration. Serum high-density lipoprotein cholesterol and triglyceride levels remained unchanged. No significant clinical or laboratory adverse effects were observed, including muscular symptoms, ophthalmologic abnormalities, or alterations in serum creatine kinase, urea nitrogen, creatinine, transaminases, and CsA levels. Peak and trough plasma concentrations of active lovastatin were comparable to those reported in normal subjects receiving a higher lovastatin dose without CsA. It was concluded that the administration of low-dose (10 to 20 mg/day) lovastatin to renal transplant recipients receiving concomitant CsA can be safe and effective in lowering serum cholesterol.
