Patients in groups A, B, and C received 48 weeks of treatment with pegylated IFNα-2a (Pegasys, Roche), 180 μg per week, by subcutaneous injection. Patients in treatment group B also received ribavirin (Copegus, Roche) at 1000 to 1200 mg/d in 2 divided doses based on body weight (those weighing > 75 kg received the higher dose). Patients in group C received pegylated IFNα-2a alone for the first 5 weeks, then received a further 48 weeks of therapy with pegylated IFNα-2a plus ribavirin dosed according to weight. There were no statistically significant differences in the response rates of patients in the 3 groups. The right-most column shows the mean CXCL10 levels (± SD) for each group at baseline. There was no statistically significant difference in the level of CXCL10 in pretreatment plasma samples from patients in the 3 groups.
