OBJECTIVES: The aim of this study was to evaluate the efficacy and indication of combination therapy with ribavirin plus peginterferon-alpha-2b in chronic hepatitis C virus (HCV) patients aged 65 years and older. METHODS: Five hundred and ninety-one consecutive HCV patients were treated with combination therapy. These patients were divided into elder patients (> or = 65 years) (n=115) and younger patients (< 65 years) (n=476). The clinical characteristics, sustained virological response (SVR) rates and discontinuation rates were compared between the two groups. RESULTS: Compared with younger patients, baseline haemoglobin levels and baseline platelet counts were significantly lower (P<0.0001, P=0.013 respectively) and fibrosis was more advanced in elderly patients (P=0.0310). Moreover, the SVR rate was significantly lower (37.4 vs. 51.5%; P=0.0067) while the combination therapy discontinuation rate was significantly higher (32.2 vs. 17.0%; P=0.0003) in elderly patients. A multivariate analysis revealed that HCV load and genotype were significantly associated with an SVR in elderly patients. An SVR was achieved in over 50% of elderly male patients with genotype 1 and HCV RNA concentrations under 2,000,000 IU/ml. In contrast, the SVR rate was under 30% in elderly male patients with genotype 1 and with HCV RNA concentrations over 2,000,000 IU/ml and in all elderly female patients with genotype 1. CONCLUSIONS: The SVR rate was lower in elderly patients than in younger patients. However, in elderly patients combination therapy was most beneficial for genotype 1 patients, male patients with HCV RNA concentrations < 2,000,000 IU/ml and patients with genotype 2.
