Background & Aims: Patient adherence to prescribed antiviral therapy in human immunodeficiency virus infection enhances response. We evaluated the impact of adherence to combination therapy with interferon or peginterferon plus ribavirin in chronic hepatitis C patients. Methods: We assessed the effect of dose reduction on sustained virologic response (SVR) from prior trials with interferon alpha-2b plus ribavirin (n = 1010) or peginterferon alpha-2b 1.5 mug/kg/week plus ribavirin (n = 511). The actual treatment administered was verified from drug dispensing/return records and patient diaries. Two groups were defined: (1) patients who received greater than or equal to80% of both their total interferon and ribavirin doses for greater than or equal to80% of the expected duration of therapy and (2) patients who received reduced doses (80% of their interferon or peginterferon alpha-2b and ribavirin dosage for the duration of treatment in the setting of a clinical trial exhibit enhanced sustained response rates. Our results suggest that adherence will enhance the likelihood of achieving an initial virologic response. Adherence beyond 12-24 weeks will be advantageous only for those patients who have achieved such an early virologic response.
