Background/Aims : Hepatitis B and C viruses (HBV and HCV) are two clinically distinct but related diseases. Pooled data from five studies of peginterferon alpha‐2a in patients with chronic HCV infection (CHC) were compared with two studies of the drug in patients with chronic HBV infection (CHB). Method : The HBV studies included both hepatitis B e antigen (HBeAg)‐positive ( n =271) and HBeAg‐negative ( n =177) patients; 791 patients took part in the HCV trials. In all studies, patients were treated with 180 μg peginterferon alpha‐2a monotherapy once weekly for 48 weeks. The number of adverse events (AEs), discontinuations and dose modifications were documented. Health‐related quality of life (HRQL) was assessed using the Short‐Form 36 questionnaire. Safety was assessed throughout the treatment period. A 24‐week treatment‐free follow‐up period was also included. Results : Differences (HBV vs HCV) were observed in the incidence of AEs (88–89 vs 96–100%), serious AEs (4–5 vs 7–16%) and treatment withdrawals (6–8 vs 17–33%). The frequency of depression‐related events was lower in CHB patients (4 vs 22%, P <0.001), as was the impact of treatment on HRQL. Conclusions : The safety and tolerability of peginterferon alpha‐2a in patients with CHB compares favourably with that observed in CHC patients, with a lower incidence of common interferon‐related AEs and a significantly lower incidence of depression.
