Combination therapy with ribavirin and interferon improves sustained virological response in chronic hepatitis C patients, including those with prior treatment failures. However, this combination also increases adverse events and treatment discontinuation rates.

Area of Science:

  • Hepatology and Viral Gastroenterology
  • Clinical Pharmacology and Therapeutics

Background:

  • Chronic hepatitis C is a significant global health issue, leading to liver disease and mortality.
  • Interferon-based therapies are standard, but efficacy in relapsed or non-responder patients requires further investigation.

Purpose of the Study:

  • To evaluate the efficacy and safety of ribavirin, alone or combined with alpha interferon, for chronic hepatitis C.
  • To assess treatment outcomes in interferon-naive patients, relapsers, and non-responders.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials.
  • Searches included major electronic databases (Cochrane, MEDLINE, EMBASE) and manual searches.
  • Primary outcomes: sustained virological response, morbidity, and mortality.

Main Results:

  • Ribavirin monotherapy showed no significant benefit over placebo for virological or histological response.
  • Combination therapy significantly improved sustained virological response rates in naive (26%), relapser (33%), and non-responder (11%) patients compared to interferon alone.
  • Combination therapy increased adverse events and treatment discontinuation but did not significantly impact morbidity or mortality.

Conclusions:

  • Combination therapy with ribavirin and alpha interferon enhances sustained virological, biochemical, and histological responses across different patient groups.
  • The improved efficacy of combination therapy is accompanied by an increased incidence of adverse events.
