Effect of donor hepatitis C on liver graft survival

Management of the Potential Organ Donor in the ICU: Society of Critical Care Medicine/American College of Chest Physicians/Association of Organ Procurement Organizations Consensus Statement

This document was developed through the collaborative efforts of the Society of Critical Care Medicine, the American College of Chest Physicians, and the Association of Organ Procurement Organizations. Under the auspices of these societies, a multidisciplinary, multi-institutional task force was convened, incorporating expertise in critical care medicine, organ donor management, and transplantation. Members of the task force were divided into 13 subcommittees, each focused on one of the following general or organ-specific areas: death determination using neurologic criteria, donation after circulatory death determination, authorization process, general contraindications to donation, hemodynamic management, endocrine dysfunction and hormone replacement therapy, pediatric donor management, cardiac donation, lung donation, liver donation, kidney donation, small bowel donation, and pancreas donation. Subcommittees were charged with generating a series of management-related questions related to their topic. For each question, subcommittees provided a summary of relevant literature and specific recommendations. The specific recommendations were approved by all members of the task force and then assembled into a complete document. Because the available literature was overwhelmingly comprised of observational studies and case series, representing low-quality evidence, a decision was made that the document would assume the form of a consensus statement rather than a formally graded guideline. The goal of this document is to provide critical care practitioners with essential information and practical recommendations related to management of the potential organ donor, based on the available literature and expert consensus.

Hepatitis C and liver transplantation: enhancing outcomes and should patients be retransplanted

Hepatitis C (HCV)-related end-stage liver disease is the most common indication for liver transplantation. Safe expansion of the donor pool with improved rates of deceased donation and more widespread use of living and extended criteria donation are likely to decrease wait list mortality. In addition, improved antiviral treatments and a better understanding of the delicate balance between under- and over-immunosuppression in this population are needed. Finally, when recurrent advanced fibrosis occurs, the criteria for patient selection for retransplantation remain widely debated. This article reviews the literature on these topics and the work being done in each area to maximize outcomes in patients receiving transplants for HCV-related cirrhosis.

Outcomes of hepatitis C- and hepatitis B core antibody-positive grafts in orthotopic liver transplantation

The use of hepatitis B core antibody (HBcAb)- and hepatitis C virus antibody (HCV+) liver grafts for transplantation in selected populations has not affected patient and graft survival. We reexamined the clinical outcomes of using these HBcAb+ and HCV+ grafts at our institution, in addition to studying recipients of combined HBcAb+/HCV+ grafts. We identified 377 patients who underwent transplantation for either hepatitis B and/or hepatitis C, or received both HBcAb+ and HCV+ grafts. Patient and graft survival at 5 years posttransplantation was 73% and 71%, respectively, in the HBcAb+ grafts compared with 81% and 75% in the HBcAb- grafts (P =.65; P =.94). For HCV+ grafts, patient and graft survival at 5 years posttransplantation was 89% and 73%, respectively, compared with 69% and 59% in the HCV- grafts; (P =.22; P =.77). The 5-year patient and graft survival rate in those who received combined HBcAb+/HCV+ grafts was 74% and 69%, respectively, and there was no statistical difference compared with the HBcAb+ and HCV+ grafts (P =.76; P =.90). The 5-year patient and graft survival rate in patients who received dual HBV prophylaxis with hepatitis B immunoglobulin (HBIg) and lamivudine was 88% and 84%, respectively, which was significantly higher than for patients who received single prophylaxis or no prophylaxis (P <.01; P =.02). Our study supports previous observations that patient and graft survival is not affected with the use of HBcAb+ and HCV+ grafts, and that dual prophylaxis with HBIg and lamivudine offers substantial survival benefits. Furthermore, the use of combined HBcAb+/HCV+ grafts did not impact patient or graft survival. This provides a potential new pool of donor livers that can be used for transplantation in select patients.
