Safety and efficacy of combined ezetimibe/simvastatin treatment and simvastatin monotherapy in patients with non-alcoholic fatty liver disease

摘要

Background Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases all over the world. In patients with a high cardiovascular risk the decrease of cholesterol level is especially important. The primary goal of this study is to observe the safety and efficacy of combined ezetimibe / simvastatin treatment and simvastatin monotherapy in patients with NAFLD and high cardiovascular risk disease. The secondary goal of this investigation was to compare the safety and efficacy of combined ezetimibe / simvastatin treatment with simvastatin monotherapy. Material and Method The data of 45 patients with NAFLD associated with type2 diabetes and metabolic syndrome were examined. They were diagnosed and treated in Buda?rs Health Centre between 2005 and 2008. Twenty-six of the patients were treated with simvastatin (20 mg/day) and 19 individuals were given ezetimibe / simvastatin therapy (10/10 mg). The safety (aspartate-aminotransferase-AST-, alanine-aminotransferase-ALT- and creatine kinase-CK-values) and efficacy (cholesterol, low density lipoprotein-LDL- cholesterol, high density lipoprotein-HDL- cholesterol and triglyceride) of the treatments had been studied for six months of the treatment period. Results Ezetimibe/simvastatin treatment resulted in a significant decrease in ALT (63.78+/-5.12 vs 32.57+/-3.92 U/L; p<0.0001) and AST (50.79+/-3.66 vs 23.68+/-3.42 U/L; p<0.0001). Simvastatin monotherapy also yielded significant decrease in ALT (66.58+/-6.13 vs 29.46+/-4.07 U/L; p<0.0001) and AST (59.61+/-5.97 vs 24.00+/-3.87 U/L; p<0.0001). Comparing the two treatment groups, simvastatin monotherapy reduced ALT (37.11+/-8.01 vs 31.21+/-7.08 U/L; p<0.0112) and AST (35.61+/-7.20 vs 27.10+/-5.22 U/L; p
