    Abstract:
    BACKGROUND AND AIMS: Pegylated interferon (PEG-IFN) α-2b and ribavirin (RBV) treatment of chronic hepatitis C virus (HCV) infection is associated with a substantially elevated risk of discontinuation. The aim of this study is to evaluate the reason for premature discontinuation during PEG-IFN α-2b and RBV treatment due to adverse effects in patients with chronic HCV infection. METHODS: A total of 2871 Japanese patients who had chronic HCV infection treated with PEG-IFN α-2b and RBV were screened. We prospectively investigated the reasons for premature discontinuation of treatment classified by sex and age, and analyzed the timing of discontinuation. RESULTS: Of the 2871 patients, 250 (8.7%) discontinued treatment because of adverse effects. The main reasons for premature discontinuation were neurovegetative symptoms (n = 77, 30.8%), depression-related syndrome (n = 46, 18.4%), hematologic effects (n = 41, 16.4%) and dermatologic effects (n = 27, 10.8%). The rate of discontinuation of treatment for patients aged ≥ 65 years was significantly higher than for patients aged < 65 years, for both men (P < 0.0001) and women (P = 0.0121). Moreover, the frequency of discontinuation due to neurovegetative symptoms, depression-related syndrome, and hematologic effects for men aged ≥ 65 years was significantly higher than for those aged < 65 years (P = 0.0001, P = 0.0016, and P = 0.0170, respectively), but not for women. CONCLUSION: Premature discontinuation due to the adverse effects of PEG-IFN α-2b and RBV treatment by patients with chronic HCV infection is mainly due to neuropsychiatric symptoms and is more common for older than for younger patients.
