Bile acids show promise in improving liver enzyme levels for viral hepatitis B and C. However, more high-quality research is needed to confirm benefits for viral markers and disease progression.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Pharmacology

Background:

  • Viral hepatitides are a significant global health concern causing liver disease.
  • Previous studies on bile acids for viral hepatitis lacked conclusive evidence regarding their efficacy.

Purpose of the Study:

  • To systematically evaluate the beneficial and harmful effects of bile acids in patients with viral hepatitis.
  • To synthesize findings from randomized clinical trials to inform clinical practice.

Main Methods:

  • Comprehensive literature searches were conducted across multiple databases including MEDLINE, EMBASE, and Cochrane Library.
  • Randomized clinical trials comparing bile acids with placebo or no intervention for viral hepatitis were included.
  • Data extraction and quality assessment were performed independently by two reviewers.

Main Results:

  • Ursodeoxycholic acid (UDCA) showed potential benefits in reducing viral markers and abnormal transaminase levels in hepatitis B.
  • Bile acids significantly decreased abnormal alanine aminotransferase levels in chronic hepatitis C but did not impact viral RNA or cirrhosis.
  • No severe adverse events were reported; however, no trials of high methodological quality were identified.

Conclusions:

  • Bile acids demonstrate a significant improvement in serum transaminase levels for hepatitis B and C.
  • Insufficient evidence exists to support or refute the effects of bile acids on viral markers, mortality, or liver histology.
  • High-quality randomized clinical trials are essential to establish definitive conclusions on the role of bile acids in viral hepatitis management.
