RESUMO

Incentives for organ donation, currently prohibited in most countries, may increase donation and save lives. Discussion of incentives has focused on two areas: (1) whether or not there are ethical principles that justify the current prohibition and (2) whether incentives would do more good than harm. We herein address the second concern and propose for discussion standards and guidelines for an acceptable system of incentives for donation. We believe that if systems based on these guidelines were developed, harms would be no greater than those to today's conventional donors. Ultimately, until there are trials of incentives, the question of benefits and harms cannot be satisfactorily answered.

RESUMO

BACKGROUND: Individuals greater than 60 years old donate an important portion of the organs available for orthotopic liver transplantation (OLT), but use of donors in this age group remains controversial. We hypothesized that proper selection of donors older than age 60 would not disadvantage recipients in terms of patient and graft survival. STUDY DESIGN: All OLTs performed at our center between January 1, 1990, and July 31, 2007, were divided into groups based on donor age: donors 60 years old or more and donors less than 60 years old. Recipients in each group were compared based on graft and patient survival at 1, 3, and 5 years, Model for End-Stage Liver Disease (MELD) scores, cold ischemic times, and era of transplant (before or after 2001). RESULTS: There were 741 recipients who met inclusion criteria. Ninety-one patients received livers from donors 60 years old or older, and 650 patients had donors younger than 60 years old. Overall patient survival rates in the group using donors 60 or older were 86.8%, 72.6%, and 67.6% at 1, 3, and 5 years, respectively, and did not differ significantly from survival in the group receiving transplants from donors less than 60 (87.1%, 81.8%, and 75.5%; p=0.39). The 1-, 3-, and 5-year graft survivals in patients receiving transplants from donors 60 or older were 82.4%, 65%, and 62.5%, respectively, and were not significantly different from those in the group using donors younger than 60 (84%, 78.6%, and 72.3%, respectively; p=0.39). Neither patient survival nor graft survival in recipients of organs from donors 60 or older was affected by Model of End-Stage Liver Disease score. Recipients of older-donor livers had improved outcomes after 2001, which correlated with significant improvements in cold ischemic times. CONCLUSIONS: Our data suggest that age alone does not adversely affect recipient outcomes. When properly selected, donors older than 60 represent an important and safe increase in the liver donor pool.

RESUMO

Although interferon alfa (IFN-alpha) and ribavirin are widely used in the treatment of hepatitis C, their role in the transplant recipient is unclear. We conducted a pilot study to determine the efficacy and safety of this therapy in transplant recipients with recurrent hepatitis C. Patients at least 6 months posttransplantation were treated with IFN-alpha 3 million units 3 times a week subcutaneously and ribavirin 800 mg daily by mouth for 48 weeks followed by ribavirin monotherapy for 24 weeks. The primary end point was sustained virologic response, and secondary end points included biochemical, virologic, and histologic responses at the end of combination treatment. Thirty-eight patients initiated therapy but 16 withdrew due to adverse effects, including 2 with myocardial infarction. Median age was 50 years; 74% were men, and 91% had genotype 1. The median interval between transplantation and enrollment was 23 months. On an intention-to-treat basis, 7 patients (18%) had a biochemical and 5 (13%) had a virologic response at the end of combination treatment. Inflammatory activity did not change, but fibrosis worsened in virologic nonresponders. Ribavirin maintenance caused a further decrease in serum alanine aminotransferase levels, but hepatitis C virus (HCV) RNA levels increased. Only 2 of the 38 patients (5%) had a sustained virologic response. Several patients required treatment with erythropoietin for anemia. In conclusion, IFN-alpha and ribavirin are effective in a small proportion of liver allograft recipients with recurrent hepatitis C. Adverse effects occur commonly, requiring dose reductions and treatment withdrawal.
