Abstract
The prevalence of chronic hepatitis C virus (HCV) tends to be higher in the elderly in many countries. Aging is regarded as an unfavorable factor for liver disease progression and treatment outcome in HCV infection. The efficacy and safety of treating elderly patients remain a source of significant debate. Discrepancies in results may be attributed to dissimilarities in study design and treatment regimens. The long-term benefits of administering interferon-based therapy to elderly patients with HCV infection is a critical issue when taking the patient's remaining life expectancy into consideration. Rapid virological response is the most notable on-treatment response factor that is predictive of treatment success in elderly patients. A shortened treatment course may reduce drug-related side effects and promote treatment adherence, especially in the elderly. A regimen tailored towards super-responders might provide insights for treatment strategies in elderly patients.
