In contrast to the United States, Japanese patients with chronic hepatitis C currently treated with interferon are generally 10 to 15 years older. Older patients, however, tend to experience more frequent adverse events. This study was conducted to clarify the effect of patient age on the efficacy and safety of combination therapy. We consecutively enrolled 208 patients with naïve chronic hepatitis C. Patients were classified into three groups according to age: younger than 50 years of age (n ‫؍‬ 52); 50 to 59 years old (n ‫؍‬ 83); and 60 years of age or older (n ‫؍‬ 73). Interferon alpha-2b therapy was administered daily for 2 weeks, followed by 3 times per week for 22 weeks, while ribavirin was administered daily. Of the 208 study patients, discontinuation of therapy or dose reduction was required in 116 (56%) and was more frequent in older patient groups: 38%, 48%, and 77% for the <50, 50-59, and >60-year-old patient groups, respectively (P < .001). Multivariate analysis showed patient age to be independently associated with adherence to therapy. A sustained virological response was achieved in 77 (37%) patients, with genotype, viral load, and adherence to therapy associated with this achievement. A tendency toward a lower sustained virological response rate was seen in the older patients. In conclusion, patient age is an important factor contributing to the safety of combination therapy. Thus, treatment schedule should be modified, or other therapeutic modalities should be considered for older patients with chronic hepatitis C. (HEPATOLOGY 2006;43:54-63.)

Pretreatment hepatic fibrosis score, age, and alcohol consumption may affect development of HCC even in sustained virologic responders. Thus, patients with these factors should be carefully followed even after eradication of the virus.

Objective The efficacy of lamivudine for fulminant hepatitis B has been reported in Europe and West Asia. However, in

We investigated the effects of zinc supplementation on clinical observations in chronic hepatitis C patients receiving pegylated interferon (PEG-IFN) ␣-2b plus ribavirin combination therapy. Patients were randomly allocated to receive 150 mg polaprezinc (zinc group, n ϭ 11) or no supplement (control group, n ϭ 12) daily in addition to PEG-IFN ␣-2b plus ribavirin therapy and 300 mg vitamin E and 600 mg vitamin C supplementation daily for 48 wk. Among the patients who continued treatment, the serum alanine aminotransferase (ALT) level at 12 wk in the zinc group was significantly lower than that in the control group. All patients in the zinc group (9/9) and 67% (8/12) of the control patients at 24 wk, and all patients in the zinc group (7/7) and 60% (6/10) of the control patients at 48 wk showed a decrease in serum ALT levels to within the normal range (7-44 U/L). HCV RNA disappeared in all patients (7/7) in the zinc group and in 8 of 10 control patients at 48 wk. Polaprezinc supplementation decreased plasma thiobarbituric acid reactive substances and prevented the decrease of polyunsaturated fatty acids of erythrocyte membrane phospholipids. No significant differences were observed in the dosage of medicines or other clinical data during the treatment. These observations indicate that polaprezinc supplementation may have induced some antioxidative functions in the liver which resulted in reduced hepatocyte injury during PEG-IFN ␣-2b plus ribavirin therapy.
