375 GENERATION OF THE PREDICTION MODELS FOR THE DEVELOPMENT OF HEPATOCELLULAR CARCINOMA IN CHRONIC HEPATITIS B AND EXTERNAL VALIDATION BY INDEPENDENT COHORTS

Conclusion:HBsAg reversion occurs after renal transplantation with an incidence of 0.7 per 100 patient-year and is followed by reactivation.This intervenes mainly in the first post transplantation year.Ethnic background, acute rejection episodes, and absence of anti-HBs Ab before transplantation appear as risk factors for reactivation.Patients with resolved hepatitis B but without protective anti-HBs Ab should receive vaccination.
