Contradictory Immune Response in Post Liver Transplantation Hepatitis B and C
نویسندگان
چکیده
Hepatitis B and C often progress to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT). After OLT, hepatitis B recurrence is clinically controlled with a combination of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues. Another approach is to induce self-producing anti-hepatitis B virus (HBV) antibodies using a HBV envelope antigen vaccine. Patients who had not been HBV carriers such as acutely infected liver failure or who received liver from HBV self-limited donor are good candidate. For chronic HBV carrier patients, a successful response can only be achieved in selected patients such as those treated with experimentally reduced immunosuppression protocols or received an anti-HBV adaptive memory carrying donor liver. Hepatitis C virus (HCV) reinfects transplanted livers at a rate of >90%. HCV reinfected patients show different severities of hepatitis, from mild and slowly progressing to severe and rapidly progressing, possibly resulting from different adaptive immune responses. More than half the patients require interferon treatment, although the success rate is low and carries risks for leukocytopenia and rejection. Managing the immune response has an important role in controlling recurrent hepatitis C. This study aimed to review the adaptive immune response in post-OLT hepatitis B and C.

Background and Aim: Chronic liver disease and its complications are major problems in renal transplant recipients. Hepatitis B and C virus infections are currently the main causes of chronic liver disease in this group, and these may affect allograft outcome. Whether hepatitis B and C virus infections after renal transplantation adversely affect graft and patient survival, remains controver...
متن کاملHepatitis C Recurrence after Orthotopic Liver Transplantation: Mechanisms and Management
Chronic Hepatitis C (HCV) infection is the leading indication for orthotopic liver transplantation and recurrence is nearly universal. Chronic HCV infection is frequently established through evasion of the innate immune system. Priming of adaptive immune responses modulate the severity and rate of fibrosis progression. Those with demonstrable viremia entering the transplant period uniformly suf...

INTRODUCTION Regulatory T (Treg) and type 1 regulatory T (Tr1) cells facilitate hepatitis C virus (HCV) recurrence after orthotopic liver transplantation (OLT). However, their frequencies and effects on HCV-specific immune responses have not been well investigated. METHODS We determined Treg and Tr1 frequencies in OLT patients with hepatitis C and assessed their associations with HCV-specific...

1. Factors associated with a lower rate of recurrent hepatitis B post-liver transplantation (LT) are negative hepatitis B e antigen and/or serum hepatitis B virus DNA pre-LT, hepatitis D virus superinfection, and fulminant hepatitis B. 2. Long-term intravenous hepatitis B immune globulin (HBIG) monotherapy can reduce the overall rate of recurrent hepatitis B to 20% to 35%. 3. Long-term lamivudi...

Results of liver transplantation (LT) for hepatitis B have improved significantly with the use of hepatitis B immune globulin (HBIG) and/or lamivudine. The aim of this study is to review the long-term outcome of patients who underwent LT for hepatitis B. Records of 41 patients who underwent LT for hepatitis B and survived 3 months or longer post-LT were reviewed. Twenty patients were administer...
