Core Tip
Core tip: The ideal endpoint of antiviral therapy is HBsAg loss, a difficult goal to obtain, especially in HBeAg negative patients. A Caucasian 44-year-old male patient, HBeAg negative, genotype D, received lamivudine and, 4 years later, added adefovir because of a virological breakthrough. Five years later, considering his age, liver stiffness (4.3 kPa) and HBsAg levels (3533 IU/mL), we added Peg-interferon α-2a for six months (3 in combination with nucleos(t)ide analogues followed by 3 of Peg-interferon monotherapy), obtaining a complete HBsAg clearance. This result has important clinical and pharmaco-economic implications, since nucleos(t)ide analogues therapy in HBeAg negative patients is considered a long-lasting/life-long treatment.
