Fibrosing cholestatic hepatitis is a deleterious manifestation of hepatitis B virus infection in immunocompromised patients. Without treatment, this condition is usually fatal within weeks of onset. Liver retransplantation has not been successfully performed to date, and treatment intervention was generally unsuccessful before the advent of adefovir dipivoxil. However, concerns have been expressed about the use of this agent in patients who are renally compromised. A 40-year-old liver transplant recipient with hepatitis B virus reinfection, resistance to lamivudine, and fibrosing cholestatic hepatitis complicated by terminal renal impairment and spontaneous bacterial peritonitis was treated with adefovir dipivoxil 10 mg after every dialysis. Since initiating treatment with adefovir dipivoxil 10 mg, a dramatic virologic and clinical improvement was observed in this patient. The patient returned to work full-time within 6 months of starting adefovir dipivoxil without the need for liver retransplantation. Serum HBV DNA (Amplicor HBV; Roche Diagnostics, Basle, Switzerland) decreased by 6 log 10 copies/mL and became negative (< 400 copies/mL) within 8 weeks of treatment and remains negative at the last available assessment. The patient continues to require renal dialysis, but is generally well. H epatitis B virus (HBV) infection is associated with high mortality in immunosuppressed patients. 1-4 A particularly deleterious form of hepatitis B is fibrosing cholestatic hepatitis (FCH), characterized by hepatocyte ballooning degeneration and cellular cholestasis, but only mild inflammatory infiltrates. 5 Although success in treating HBV with nucleoside analogues after transplantation has been achieved, 6-9 similar approaches for the treatment of FCH have, in most cases, failed to prevent liver failure and subsequent death. 10 Successful treatment of FCH has been reported in two lamivudine-treated kidney recipients 11-12 and three patients receiving adefovir dipivoxil. [13][14][15] However, none of these patients had renal impairment.Adefovir dipivoxil, a potent inhibitor of HBV replication, is the orally bioavailable prodrug of adefovir, a nucleotide analogue of adenosine monophosphate. Adefovir dipivoxil 10 mg once daily has shown efficacy against hepatitis B e antigen (HBeAg)-positive chronic hepatitis B, 16 HBeAg-negative (presumed precore mutant) chronic hepatitis B, 17 lamivudine-resistant chronic hepatitis B, 18 and lamivudine-resistant chronic hepatitis B patients co-infected with HIV. 19 Adefovir dipivoxil has just been approved by the FDA.We report the successful treatment with adefovir dipivoxil of a patient suffering from lamivudine-resistant FCH further complicated by pre-existing cirrhosis, terminal kidney insufficiency, and spontaneous bacterial peritonitis.
CaseA 33-year-old male patient underwent liver transplantation for HBV-induced cirrhosis in 1993. The patient received prophylactic hepatitis B immunoglobulin, but reinfection, measured by hepatitis B serum surface antigen (HBsAg) positivity, occurred w...
