High-dose ursodeoxycholic acid in primary sclerosing cholangitis: a 5-year multicenter, randomized, controlled study.

Background & Aims: There is no medical treatment of proven benefit for primary sclerosing cholangitis. This study aimed at studying the effect of a higher dose of ursodeoxycholic acid than previously used on survival, symptoms, biochemistry, and quality of life in this disease.

Methods: A randomized placebo-controlled study was performed in tertiary and secondary gastroenterology units.

Treatment with pegylated interferon and ribavarin in HCV infection with genotype 2 or 3 for 14 weeks: a pilot study.

The aim of this study was to determine the efficacy of 14 weeks of treatment in patients infected with hepatitis C virus (HCV) genotype 2 or 3 who achieve early virological response (EVR). In a noncontrolled multicenter trial, 122 treatment-naive patients received 1.5 mug/kg pegylated interferon alfa-2b subcutaneously once weekly and 800 to 1,400 mg/d ribavirin based on body weight.
