Insights
Hepatitis C (HCV) treatment with Peg-IFN and ribavirin causes significant adverse effects across organ systems. Effective management strategies are crucial for successful HCV eradication and patient adherence.
Area of Science:
- Hepatology
- Infectious Diseases
- Pharmacology
Background:
- Hepatitis C virus (HCV) infection affects 2-3% of the global population, leading to end-stage liver disease and hepatocellular carcinoma.
- Pegylated interferon-alpha (Peg-IFN) and ribavirin combination therapy offers a 40-90% cure rate for HCV but is limited by frequent, serious adverse effects.
- Adverse effects significantly impact treatment adherence, with higher discontinuation rates in clinical practice compared to clinical trials.
Purpose of the Study:
- To systematically review the adverse effects of Peg-IFN-α and ribavirin on multiple organ systems.
- To recommend consensus-based management strategies for these adverse effects.
- To improve the successful treatment and delivery of HCV therapy.
Main Methods:
- Comprehensive literature review of Peg-IFN-α and ribavirin therapy.
- Systematic description of adverse effects across organ systems.
- Analysis of regional and global variability in adverse effect management.
Main Results:
- Peg-IFN and ribavirin cause off-target effects impacting most organ systems, including hematologic, dermatologic, neurologic, immunologic, gastrointestinal, pulmonary, cardiovascular, and ocular.
- Adverse effects are a major barrier to treatment, leading to discontinuation in 10-15% of patients in trials and higher rates in practice.
- Variability exists in reported adverse effects and management strategies globally.
Conclusions:
- Effective recognition and management of Peg-IFN and ribavirin adverse effects are critical for successful chronic HCV treatment.
- Consensus approaches to managing these side effects are needed to optimize patient outcomes.
- Addressing adverse effects can improve treatment uptake, delivery, and adherence, ultimately enhancing HCV eradication rates.
Abstract:
HCV infects approximately 2-3% of the global population and is a leading cause of end-stage liver disease and hepatocellular carcinoma. Treatment of HCV infection with Peg-IFN in combination with ribavirin can eradicate HCV infection in 40-90% of patients; however, a major barrier to treatment uptake and delivery is the association of this therapy with frequent and, at times, serious adverse effects. Recognition and effective management of these adverse effects are critical components of the successful treatment of chronic HCV infection. In clinical trials, approximately 10-15% of patients discontinue Peg-IFN and ribavirin therapy due to adverse effects; however, in clinical practice, the rate of treatment discontinuation has been reported to be substantially higher. The off-target effect of Peg-IFN and ribavirin impacts most, if not all, organ systems; the most common adverse effects are hematologic, dermatologic, neurologic, immunologic, gastrointestinal, pulmonary, cardiovascular, and ocular. Regional and global variability exists in the nature of these adverse effects and the strategies employed to ameliorate their impact. This article provides a comprehensive literature review that systematically describes the adverse effects of Peg-IFN-α and ribavirin on various organ systems and, more importantly, recommends consensus approaches to managing those effects.
