Insights
Hepatitis B (HBV) and Hepatitis C (HCV) infections significantly increase mortality in chronic kidney disease (CKD) patients. Careful donor selection and targeted therapies are crucial for managing these viral infections in CKD and transplant recipients.
Area of Science:
- Nephrology
- Hepatology
- Transplantation Immunology
Background:
- Hepatitis B virus (HBV) and hepatitis C virus (HCV) are leading causes of liver disease in chronic kidney disease (CKD) patients.
- These viral infections are associated with increased mortality and complications in CKD patients, including post-transplant outcomes.
Purpose of the Study:
- To review the impact of HBV and HCV on CKD patient survival and post-renal transplant outcomes.
- To discuss current therapeutic strategies and donor selection criteria for HBV and HCV in CKD and transplant populations.
Main Methods:
- Literature review of studies investigating HBV and HCV in CKD patients.
- Analysis of registry data on renal transplantation outcomes in HCV-infected recipients.
- Summary of current treatment guidelines for HBV and HCV in dialysis and post-transplant settings.
Main Results:
- HBV and HCV infections contribute to excess mortality in CKD patients, partly due to liver disease complications.
- HCV infection negatively impacts renal transplant survival, associated with both hepatic and extrahepatic complications.
- Transmission of HCV via donor kidneys is confirmed, increasing recipient mortality risk; restricting infected grafts to viremic recipients is advised.
- Limited data exists for newer HBV therapies in CKD; lamivudine is the most studied.
- Conventional interferon monotherapy is the standard for HCV in dialysis patients, with limited use post-transplant.
Conclusions:
- HBV and HCV pose significant risks to CKD patients and renal transplant recipients.
- Strategic donor selection and appropriate, guideline-adherent therapies are essential for managing these viral infections.
- Further research is needed on novel HBV therapies in the CKD population.
Abstract:
The most common cause of liver disease in patients with chronic kidney disease (CKD) remains infection by hepatitis B virus (HBV) and/or hepatitis C virus (HCV). The adverse effects of HBV and/or HCV infections upon survival in patients with CKD have been repeatedly confirmed. An excess risk of death in HBsAg positive or anti-HCV antibody-positive patients may be at least partially attributed to chronic liver disease with its attendant complications. A negative impact of HCV infection on survival after renal transplantation has been linked to extrahepatic complications, including chronic glomerulonephritis, sepsis, chronic allograft nephropathy, post-transplantation diabetes mellitus, and abnormal metabolism of calcineurin-inhibitors. Transmission of HCV infection by grafts from HCV-infected donors has been unequivocally demonstrated. Registry analyses suggest that recipients of kidneys from anti-HCV antibody positive donors are at increased risk of mortality. Renal grafts from HCV-infected donors should be restricted to viremic anti-HCV positive recipients. Several drugs have been recently licensed for therapy of HBV infection but availabledata in patients with CKD is mostly limited to experience with lamivudine. The standard of care for hepatitis C infection in patients on regular dialysis is monotherapy with conventional interferon, according to recent guidelines. Only dire circumstances justify interferon use after renal transplantation.
