No effective medical therapy is available for all patients with nonalcoholic steatohepatitis (NASH). Ursodeoxycholic acid (UDCA) has been suggested to be of benefit based on open label clinical studies. We randomized 166 patients with liver biopsy-proven NASH to receive between 13 and 15 mg/kg/d of UDCA or placebo for 2 years. End points included changes in liver test results and liver histology at 2 years of therapy. The treatment groups were comparable at entry with regard to age, gender, risk factors for NASH, serum liver biochemistries, and baseline liver histology. A total of 126 patients completed 2 years of therapy. Pre-and posttreatment liver biopsies were available in 107 patients for review at the end of the study. UDCA was well tolerated and body weight was stable during the study duration. Serum liver biochemistries were stable or improved in both the UDCA and placebo-treated groups. Changes in the degree of steatosis, necroinflammation, or fibrosis that occurred with therapy were not significantly different between the UDCA and placebo groups. In conclusion, 2 years of therapy with UDCA at a dose of 13 to 15 mg/kg/d, although safe and well tolerated, is not better than placebo for patients with NASH. (HEPATOLOGY 2004; 39:770 -778.)
Summary
Background : Cystic fibrosis causes exocrine pancreatic insufficiency, leading to malabsorption. Supplemental pancreatic enzyme therapy alleviates the concomitant malnutrition experienced by cystic fibrosis patients. It is recognized that patients experience variations in clinical response to different brands of enzymes. This has prompted the US Food and Drug Administration to require that enzyme supplements be subjected to New Drug Applications.
Aim : To investigate the safety and efficacy of supplemental pancreatic enzyme therapy in cystic fibrosis subjects.
Methods : We compared two doses of one formulation of enteric‐coated pancreatic enzymes: Ultrase MT12 (12 000 lipase units per capsule) and Ultrase MT20 (20 000 lipase units per capsule), to placebo in two separate safety and efficacy studies.
Results : Mean total fat, protein and carbohydrate intake did not differ significantly between the groups. A significant difference in both fat and protein absorption occurred with the enzyme therapy groups. The Ultrase MT12 and Ultrase MT20 groups experienced a mean fat and protein absorption 79.4% and 83.8%, and 87.3% and 88.6%, respectively. No adverse events related to study drug were reported.
Conclusions : This study further supports the use of enzymes to treat pancreatic insufficiency in cystic fibrosis. Excellent fat and protein absorption was achieved with minimal adverse events and safe doses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
