title: Fibrosing cholestatic hepatitis in a transplant recipient with hepatitis B virus precore mutant.
abstract: A patient with hepatitis B virus (HBV) precore mutant (seropositive for hepatitis B surface antigen [HBsAg], anti-hepatitis B e antigen [HBeAg], and HBV DNA) who underwent orthotopic liver transplantation for end-stage liver disease is described. Sequencing of the HBV precore region of the pretransplant serum sample confirmed the presence of the precore stop-codon mutant (G-->A mutation in codon 1896) only. The patient received HBV immunoglobulin prophylaxis for 6 months but HBV recurred thereafter with a mild hepatitic flare, and he remained seropositive for HBsAg, anti-HBe, and HBV DNA. The initial hepatitic illness resolved in 3 months. The patient remained well for another 16 months before presenting with fibrosing cholestatic hepatitis (FCH). During his entire initial hepatitic flare, quiescent period, and final FCH phase, he remained seropositive for HBsAg, anti-HBe, and HBV DNA. Moreover, sequencing of the serum HBV DNA in final FCH phase showed the presence of the identical HBV precore mutant. Immunohistochemical staining showed extensive expression of HBsAg/pre-S1, pre-S2, and hepatitis B core antigen, but HBeAg was scarcely detectable. This case illustrates that (1) recurrence of HBV precore mutant infection can occur in liver; (2) it can give rise to FCH; and (3) hepatic accumulation of HBeAg is not essential for the development of FCH.
