Limited lamivudine and long-term hepatitis B immunoglobulin immunoprophylaxis for prevention of hepatitis B recurrence after liver transplantation.
BACKGROUND
No consensus exists concerning dosage and duration of prophylactic hepatitis B immunoglobulin and lamivudine for prevention of hepatitis B recurrence after liver transplantation (LT).


METHODS
Lamivudine was discontinued 12 months after LT, maintaining hepatitis B immunoglobulin prophylaxis in eight patients who received lamivudine treatment before LT.


RESULTS
At LT, six patients were serum hepatitis B virus (HBV)-DNA negative, whereas two patients had low serum HBV-DNA levels. Hepatitis B surface (HBs) antigen and hepatitis B core antigen stained positively by immunohistochemistry in all hepatectomy specimens. All patients remained recurrence free during the 12 months on combination therapy with normal liver histological examination and negative HBs and HB core staining on biopsy specimens. No relapse occurred after lamivudine withdrawal during a median follow-up of 17.5 months (normal transaminases, negative serum HBs antigen, and HBV-DNA).


CONCLUSIONS
Discontinuation of lamivudine 12 months after LT is feasible and safe even in patients with ongoing low viral replication at LT, providing adequate prophylaxis with hepatitis B immunoglobulins.
