Abstract

Background: Patients with malignant haematological diseases administered or no longer receiving immunosuppressive therapy are at high risk of reactivation or de novo hepatitis B infection and fulminant hepatitis. Despite promising results in the treatment of chronic hepatitis and its use in selected patients with acute hepatitis B, there is no consensus on lamivudine treatment in severe acute hepatitis portending a fatal clinical outcome.

Case reports: Of the ten patients with malignant haematological disorders who became infected with the same strain of hepatitis B virus during hospitalisation in a haematology ward, five received lamivudine (and in some cases, ganciclovir and famciclovir). The other patients received only supportive therapy, since deteriorating clinical conditions hampered specific treatment efforts. Eight patients died from acute liver failure and one from a fatal course of the haematological disease; one had a favourable outcome from the therapy. There was no significant difference in terms of survival between the treated and untreated patients.

Conclusions: Although lamivudine has proved promising in the therapy of chronic hepatitis B and of recurrent hepatitis after liver transplantation, its use in de novo severe acute hepatitis should be investigated further, particularly in immunocompromised patients.

Introduction

Infection with hepatitis B virus (HBV) leads to fulminant hepatitis (FH) in approximately 1% of patients, but carries a high mortality rate [1]. Fulminant HBV infection determines a rapid destruction of the hepatic parenchyma, leading to liver failure, death, or needing liver transplantation in more than 80% of these patients. The pathogenesis of FH is still unclear, though both viral factors and the host's immune response may play an important role [2], [3]. In particular, patients undergoing or following withdrawal of immunosuppressive therapy for oncological and haematological diseases, and patients undergoing liver transplantation for viral-related diseases are at high risk of reactivation or de novo HBV infection, often leading to a fatal clinical outcome [4], [5].

Lamivudine, a nucleoside analogue, has been approved for the treatment of chronic hepatitis B; extensive clinical studies have suggested that early treatment with the drug improves hepatic histology in patients with chronic hepatitis B, and can prevent recurrence of hepatitis B after liver transplantation [6], [7], [8]. Lamivudine has also been considered to treat selected patients with severe, acute hepatitis B [9], [10], [11].

We have recently described a nosocomial outbreak of hepatitis B, which occurred among the inpatients of a haematology unit, accounting for a fatal outcome in most infected patients [12]. Extensive epidemiological and molecular analysis showed that transmission of the same viral strain occurred from an HBsAg-positive patient with acute reactivation of the infection to all case-patients. We report here the clinical course of ten of the 11 patients with de novo acute hepatitis B involved in the outbreak, and the therapeutic approach used in all cases.

Patients

Ten patients (three males, mean age 49.5 years, range 12–68 years) were admitted between December 1997 and March 1998 in the Infectious Disease (ID) Department of San Salvatore Hospital, Pesaro, Italy; all had haematological diseases and became infected with HBV during their stay in the haematology ward of the same hospital; all patients tested positive for HBsAg, IgM anti-HBc, and serum HBV-DNA at admission. Details of the epidemiological and virological investigations are reported elsewhere

Discussion

Eight out of ten patients with acute hepatitis B who were referred to the Infectious Diseases Department of San Salvatore Hospital, Pesaro, Italy, between December 1997 and March 1998, died from acute liver failure; one probably had a fatal course of the haematological disease with a plurivisceral involvement of the lymphoma; finally, one HBV-infected patient had a favourable outcome of the hepatitis and survived. All patients had haematological disorders and had been infected with the same

    Twelve % of patients developed reactivation after 1 year of stopping CT. Reactivation most frequently follows cessation of CT but may occur during CT.2,38,39 The reported interval usually ranges from 1 to 12 months from initiation of CT but has also been upto 39 months as seen in some of our patients.40–43 We observed that 20.7% of patients needed to interrupt CT because of HBVR.
