Multicenter Study Comparative Study
Outcomes in recipients of combined heart-kidney transplantation: multiorgan, same-donor transplant study of the International Society of Heart and Lung Transplantation/United Network for Organ Sharing Scientific Registry.
In patients awaiting heart transplantation, end-stage disease of a second organ may occasionally require consideration of simultaneous multiorgan transplantation. Outcome statistics in multiorgan transplant recipients are needed to define optimal utilization of scarce donor resources. Incidence of cardiac allograft rejection, actuarial recipient survival, and cardiac allograft rejection-free survival were evaluated in 82 recipients of 84 simultaneous heart and kidney transplants. ⋯ The rejection-free survival rates at 1, 3, and 6 months were 88%, 74%, and 71% in the double-organ recipients, as compared with 66%, 44%, and 39%, respectively, in the single-organ recipients. Compared with isolated heart transplantation, combined heart-kidney transplantation does not adversely affect intermediate survival and results in a lower incidence of treated cardiac allograft rejection. The findings suggest that combined heart-kidney transplantation may be an acceptable option in a small subset of potential heart transplant recipients with severe renal dysfunction.

Comparative Study
Long-term follow-up of hepatitis C virus infection among organ transplant recipients: implications for policies on organ procurement.
Hepatitis C virus (HCV) infection causes slowly progressive liver disease. Therefore, the full impact of HCV infection after transplantation may require 5-10 years of follow-up. ⋯ The two studies presented in this report provide an apparent paradox, with respect to the impact of HCV infection acquired at the time of transplantation versus before transplantation on posttransplantation clinical outcomes. However, the increased mortality among recipients who acquired HCV infection before transplantation, but not among recipients who acquired HCV at the time of transplantation, could be explained by the longer duration of HCV infection in the former group. These findings are consistent with the known slowly progressive nature of HCV infection. However, in the absence of definitive evidence for an adverse effect on patient or graft survival, we believe that the decision to accept a kidney from an anti-HCV-positive donor should be made by the patient, after discussion with the treating physician.
