title: Ursodeoxycholic acid treatment in patients with primary biliary cirrhosis. A Swedish multicentre, double-blind, randomized controlled study.
abstract: BACKGROUND
  Ursodeoxycholic acid (UDCA) has been shown to improve serum levels of liver enzymes and bilirubin in primary biliary cirrhosis (PBC). However, it is still uncertain whether UDCA treatment also improves symptoms, liver histology, and survival without liver transplantation.
  
  
  METHODS
  We randomized 116 patients with PBC to receive 0.5 g UDCA (n = 60) or placebo (n = 56) daily for 2 years. During the next 2 years, 80% of the UDCA-treated patients and 65% of the placebo-treated patients continued to take UDCA.
  
  
  RESULTS
  UDCA improved serum enzyme values but not survival, symptoms, serum bilirubin levels, or liver histology. There was no significant difference in response between initially symptomatic and asymptomatic patients.
  
  
  CONCLUSIONS
  UDCA in a dosage of 7.7 mg/kg body weight is of little benefit in PBC. This does not exclude the possibility that larger doses have beneficial effects.
