Objective. Our aim was to evaluate the efficacy and safety of adding adefovir to lamivudine therapy for hepatitis B virus (HBV)-infected patients resistant to Ramivudine. Patients and methods. Among 17 studied patients, 7 had chronic active HBV infection and 10 were posttransplant with HBV infection (9 with de novo HBV). They received lamivudine plus adefovir therapy for 2 years. We assessed reductions in serum HBV-DNA and alanine aminotransferase (ALT) levels, loss of HBeAg (in HBeAg+ cases), and HBsAg clearance. Results. A virological response, as defined by HBV-DNA below the cut of by hybridization, was observed in 12 (70.6%) patients and loss of HBeAg in 4 (44.4%) of the 9 initially HBeAg-positive cases. A biochemical response, defined as a decreased serum ALT to the normal range, occurred in 4 (26.7%) patients. Median serum creatinine increased in 3 of 15 (20%) patients, excluding those on hemodialysis. There were two noteworthy cases of sustained HBsAg seroconversion with adefovir (11.8%): one patient with de novo, HBV infection posttransplantation and positive hepatitis C virus-RNA serology, and one patient with decompensated HBV cirrhosis in whom viral replication ceased, making him eligible for transplantation. Conclusions. Currently, adefovir is an effective rescue therapy that broadens the existing range of options for patients with lamivudine-resistant chronic hepatitis B infection, particularly those with decompensated cirrhosis awaiting a liver graft, and those with recurrent posttransplantation HBV. The relatively small biochemical response seen in these patients may be attributable to the high prevalence of concomitant hepatitis C virus infection (41%).
