Lamivudine for the treatment of hepatitis B virus reactivation following chemotherapy for non-Hodgkin's lymphoma.

Chemotherapy for non-Hodgkin's lymphoma (NHL) patients with chronic hepatitis B virus (HBV) infection may be accompanied by severe hepatitis. Of 86 consecutive NHL patients, 11 (12.8%) exhibited a positive serum HBsAg. Six of these patients (54.5%) developed acute exacerbation of chronic HBV infection following chemotherapy and received lamivudine. Five of the six patients demonstrated a clinical improvement, one patient died from fulminant hepatic failure owing to delayed lamivudine therapy and poor compliance. These data suggest that HBsAg screening is necessary before commencing chemotherapy for NHL patients in a hyperendemic area and that lamivudine is effective in treating hepatitis B reactivation during chemotherapy.
