    Abstract:
    The treatment of patients affected by active chronic hepatitis B (CHB) could be performed using a finite-time therapy with pegylated-interferon alpha (PEG-IFN) or indefinite time treatment with nucleos(t)ide analogues (NAs). Current practice guidelines do not provide the combined use of PEG-IFN and NAs, but some studies analyzed various combined approach with NAs and PEG-IFN with encouraging result. In this perspective study, we have treated 39 patients with different hepatitis B virus (HBV) genotypes, hepatitis B "e" antigen (HBeAg)-positive/negative using a sequential therapy with entecavir (ETV) 0.5 mg/day monotherapy for 12 weeks followed by combination of ETV and PEG-IFN α-2a 180 µg/week for 12 weeks, then PEG-IFN monotherapy for 36 weeks. HBeAg seroconversion rate was 68.2%; HBsAg loss was 33.3%; sustained virological response (SVR) was 64.1%; primary non-response was observed in eight patients (20.5%) after 12 weeks of PEG-IFN therapy; virological relapse was reported in six (15.3%) patients. Viral genotype and hepatitis B surface antigen (HBsAg) decline were the most important predictive factor for PEG-IFN response. The stopping rule after 12 weeks of PEG-IFN therapy is useful for identify the non-responders. Our study offers interesting and promising results using a sequential combined therapy with ETV and PEG-IFN in a cohort of young patient with active CHB. These results, however, should not be generalized and further investigations are required for the confirmation of advantage of this combination approach. J. Med.
