INTRODUCTION: Hepatitis B virus (HBV) reactivation is a major cause of morbidity and mortality in patients with hematological malignancies who receive cytotoxic chemotherapy. We have therefore carried out a prospective observational study out to assess the incidence, prevalence, and clinical course ina cohort of these patients. METHODS: HBV and HCV markers and liver function indices were monitored prospectively in 318 consecutive patients(171 males, 147 females; mean age 57 years) with hematological malignancies, who had been referred to the Hematology Division, Perugia University, between October 2005 and March 2007 and followed up for at least 6 months. RESULTS: At diagnosis, 32 patients (10%) had received HBV vaccination; 30 were responders. At least one HBV marker was positive in 70/318 patients (22%): 14 (20%) were HBsAg-positive(HBV surface antigen-positive), 13 (19%) were only anti-HBc positive (antibodies to HB core antigen), and 43(61%)were anti-HBc and anti-HBs positive. Twelve HBsAg+ patients received nucleoside/nucleotide analogs (adefovir [six patients],lamivudine [four], and combined adefovir/lamivudine[two non-responders to lamivudine]). After 6 months of therapy, HBV-DNA was negative and transaminases were normal in nine of these 12 patients (adefovir [six], lamivudina[two], adefovir + lamivudina [one]). Seroreversion was achieved in 3/13 patients (23%) who were only anti-HBc positive;all were on rituximab therapy and received adefovir. Seroreversion was not observed in any of the 43 patients who were anti-HBc- and anti-HBs positive. CONCLUSIONS: Essential to the management of patients with hematological malignancies undergoing chemotherapy are surveillance and prophylaxis of HBV infection together with prompt administration of nucleoside/nucleotide analogs in cases of reactivation and/or seroreversion.
