The primary aim of this study was to investigate the correlation between ribavirin concentration at day 29 and therapeutic response in patients with HCV genotype 2/3 infection. A total of 382 patients were randomized to 12 or 24 weeks of treatment with pegylated interferon-alfa 2a 180 μg weekly and 800 mg ribavirin daily.

Of the 382 patients, 355 had a ribavirin concentration available at day 29. SVR was 84% among patients with a ribavirin concentration ≥2 mg/L at day 29 compared to 66% in those with concentrations <2 mg/L (P = 0.002). The corresponding figures in the 12-week treatment group were 74% and 57% (P = 0.12), and in the 24-week treatment group 91% and 75% (P = 0.02), respectively. In a multivariate analysis, ribavirin concentration at day 29 was an independent predictor of SVR (P = 0.002). In conclusion, a higher plasma ribavirin concentration is associated with an increased likelihood of achieving SVR in HCV genotype 2/3 infection. Individualization of ribavirin dosing may be helpful in improving outcome, especially in the presence of unfavourable baseline characteristics. This, however, requires evaluation in a prospective trial.
