Histologic recurrence-free outcome after orthotopic liver transplantation for chronic hepatitis B

Recurrent hepatitis B (HB) following orthotopic liver transplantation (OLT) for chronic disease is common. However, an unpredictable minority of patients follow a recurrence-free course. Clinical, virologic, and pathologic data from patients surviving longer than 60 days (n=24) with pathologically confirmed nonrecurrence of HB following OLT for chronic HB were reviewed to identify factors associated with nonrecurrence of HB. Nine of 24 patients had no histologic and immunohistologic evidence of recurrent HB. In addition to pre-OLT hepatitis B e antigen (HBeAg) negativity, coexisting delta and anti-HB therapy/prophylaxis, other acquired viral infections and their therapy, and severe acute rejection due to noncompliance were considered the possible protective factors against HB recurrence in these 9 patients. Histologic and, particularly immunopathologic, evaluation of liver biopsies must be utilized in definitively diagnosing recurrence of HB.
