Abstract

Patients with dyslipidemia and advanced renal failure are at markedly increased risk of cardiovascular morbidity and mortality. We evaluated the efficacy and safety of ezetimibe administration to patients with endstage renal failure (ESRF) who are undergoing hemodialysis. Ezetimibe at 10 mg/day was given to 20 patients for 12 weeks. Efficacy was determined by monitoring lipids, and safety was determined by monitoring clinical and laboratory parameters. We also evaluated the effects of ezetimibe on surrogate markers of cholesterol absorption and synthesis. Compared to baseline values, LDL-cholesterol (LDL-C) was reduced by 24.9% (p<0.005) after 12 weeks of ezetimibe administration. Treatment with ezetimibe did not change HDL-cholesterol, triglyceride and HbA1c values but caused a significant reduction in remnant like particles-cholesterol (RLP-C, p<0.05) and high-sensitive C-reactive protein (hsCRP, p<0.05). Ezetimibe therapy decreased cholesterol absorption markers (campesterol and sitosterol) and increased a marker of cholesterol synthesis (lathosterol). A highly significant correlation was observed between alterations in LDL-C and campesterol levels in response to ezetimibe therapy. No patients reported musculoskeletal symptoms. None of the patients experienced elevations in their creatine kinase or liver transaminase levels. Ezetimibe not only reduced serum LDL-C, but also RLP-C and hsCRP, in ESRF patients. Inhibition of cholesterol absorption by ezetimibe is an important therapeutic option in these patients due to its efficacy and safety.
