Effect of Spironolactone and Vitamin E in Patients With Nonalcoholic Fatty Liver Disease
- Conditions
- Fatty LiverSteatohepatitis
- Interventions
- Drug: Spironolactone/Vitamin E
- Registration Number
- NCT01147523
- Lead Sponsor
- Aristotle University Of Thessaloniki
- Brief Summary
The primary aim of the study is the effect of spironolactone and vitamin E versus vitamin E on serum levels of adipokines 52 weeks post-treatment.
- Detailed Description
Unlike other chronic liver diseases (e.g., hepatitis C), there are no effective treatment strategy for NAFLD. Currently, the management of NAFLD includes modification of underlying risk factors, detection of patients that have progressed to cirrhosis, management of cirrhosis-related morbidity and transplantation in patients with end-stage liver disease. Diet, exercise, bariatric surgery and pharmacologic treatment, including weight loss agents, insulin sensitizers, lipid-lowering agents, ursodeoxycholic acid and vitamin E have been investigated with some promising results.
The renin-angiotensin-aldosterone system (RAAS) has been implicated in the pathogenesis of insulin resistance (IR) and nonalcoholic fatty liver disease (NAFLD). Recently, low-dose (25-50 mg/day) aldosterone antagonists in patients with heart failure diminish mortality, possibly by reducing cardiac and vascular fibrosis. Moreover, the beneficial effect of spironolactone in a mouse model with diet-induced diabetes and NAFLD has been reported. However, to our knowledge, the role of spironolactone in NAFLD patients has not been investigated yet.
The primary aim of the study is the effect of spironolactone and vitamin E versus vitamin E on serum levels of adipokines 52 weeks post-treatment.
