Efficacy and Safety of Diamel in Patients With Nonalcoholic Steatohepatitis

April 25, 2012 updated by: Catalysis SL

Efficacy and Safety of Diamel, a Nutritional Supplement, in Patients With Nonalcoholic Steatohepatitis. A Randomized and Double Blind Controlled Study

The purpose of the study is to evaluate whether the addition of Diamel, a nutritional supplement, to hypocaloric diet and exercise could improve the histological results (steatosis, necro-inflammatory activity and fibrosis), insulin resistance, aminotransferase levels and anthropometric measures in comparison with a placebo-controlled group with hypocaloric diet and exercise during 52 weeks of treatment in patients with nonalcoholic steatohepatitis.

  • Pregnancy or lactation
  • Decompensated cirrhosis
  • Presence of secondary cause of NAFL such as medications that induce steatosis (corticosteroids, estrogens, methotrexate, amiodarone, tamoxifen and calcium channel blockers) and gastrointestinal bypass surgery
  • Pharmacological treatment with some potential benefit on NAFL including ursodeoxycholic acid, vitamin E, betaine, pioglitazone, rosiglitazone, metformin, pentoxifylline or gemfibrozil
