At present there is no effective treatment for non-alcoholic fatty liver disease or its advanced form NASH.METHODS: This prospective study included 20 biopsy proven patients with NASH, metabolic syndrome(Met S) and dyslipidaemia. Biochemical parameters of the blood of the patients and an ultrasonography of the liver were performed at baseline. Then patients receivedlifestyle advice and were treated for a 12 mo period with rosuvastatin(10 mg/d) monotherapy. Patients were re-evaluated during the study at 3 mo intervals, during which biochemical parameters of the blood were measured including liver enzymes. A repeat biopsy and ultrasonography of the liver were performed at the end of the study in all 20 patients. Changes in liver enzymes, fasting plasma glucose, serum creatinine, serum uric acid(SUA), high sensitivity C reactive protein(hs CRP) and lipid profile were assessed every 3 mo. The primary endpoint was the resolution of NASH and the secondary endpoints were the changes in liver enzyme and lipid values.RESULTS: The repeat liver biopsy and ultrasonography showed complete resolution of NASH in 19 patients, while the 20 th, which had no improvement but no deterioration either, developed arterial hypertension and substantial rise in triglyceride levels during the study, probably due to changes in lifestyle including alcohol abuse. Serum alanine transaminase, aspartate transaminase, and γ-glutamyl transpeptidase were normalised by the 3rd treatment month(ANOVA P < 0.001), while alkaline phosphatase activities by the 6th treatment month(ANOVA, P = 0.01). Fasting plasma glucose and glycated haemoglobin were significantly reduced(P < 0.001). Lipid values were normalised by the 3rd treatment month. No patient had Met S by the 9th treatment month. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed solely to rosuvastatin treatment. A limitation of the study is the absence of a control group.CONCLUSION: These findings suggest that rosuvastatin monotherapy could ameliorate biopsy proven NASH and resolve Met S within 12 mo. These effects and the reduction of fasting plasma glucose and SUA levels may reduce the risk of vascular and liver morbidity and mortality in NASH patients. These findings need confirmation in larger studies.展开更多
