Despite effective antiviral treatment, hundreds of kidneys from deceased donors with hepatitis C virus (HCV) are discarded annually. Little is known about the determinants of willingness to accept HCV-infected kidneys among HCV-negative patients.At 2 centers, 189 patients undergoing initial or reevaluation for transplant made 12 hypothetical decisions about accepting HCV-infected kidneys in which we systematically varied expected HCV cure rate, allograft quality, and wait time for an uninfected kidney.Only 29% of the participants would accept an HCV-infected kidney under all scenarios, whereas 53% accepted some offers and rejected others, and 18% rejected all HCV-infected kidneys. Higher cure rate (odds ratio [OR], 3.49; 95% confidence interval [CI], 2.33-5.24 for 95% vs 75% probability of HCV cure), younger donor (OR, 2.34; 95% CI, 1.91-2.88 for a 20-year-old vs a 60-year-old hypertensive donor), and longer wait for an uninfected kidney (OR, 1.43; 95% CI, 1.22-1.67 for 5 years vs 2 years) were associated with greater willingness to accept an HCV-infected kidney. Black race modified the effect of HCV cure rate, such that willingness to accept a kidney increased less for blacks versus whites as the cure rate improved. Patients older than 60 years and prior kidney recipients showed greater willingness to accept an HCV-infected organ.Most patients will consider an HCV-infected kidney in some situations. Future trials using HCV-infected kidneys may enhance enrollment by targeting older patients and prior transplant recipients, but centers should anticipate that black patients' acceptance of HCV-infected kidneys will be reduced compared with white patients.

In light of the transplant community's efforts to increase living donation, preserving donor autonomy is essential. Understanding how often and the reasons why potential living kidney donors opt out of the donor evaluation process for nonmedical reasons is important for assessing donor voluntariness. The experiences of individuals who opt out of donation may reveal avenues for enhancing donor protections and identify modifiable deterrents to donation. A limited number of centers have reported rates of opting out between 0.2% and 22%; the reasons for declining to donate are not well studied. This article calls for further research on potential living donors who opt out of donation. We describe challenges to studying this population and offer a roadmap for an ethical approach to conducting research on individuals who withdraw from living kidney donor evaluation.

Programmed cell death (PCD) is currently one of the most intensively studied areas in cell biology. Substantial evidence now exists demonstrating the integral role of PCD in many fundamental immunologic processes; therefore, understanding the mechanisms of PCD may provide advances with broad implications in immunobiology. This Overview provides a definition of PCD, a description of known PCD biochemical pathways, and finally a discussion of the implications of PCD in transplantation.

Severe sepsis in immunosuppressed recipients of solid-organ transplants is associated with a high mortality. Conventional management of sepsis in this patient population has not specifically attempted to treat the underlying inflammatory or procoagulant responses that contribute to the development of multisystem organ failure. Drotrecogin alfa (activated, human activated protein C) has been shown to be a safe and effective adjuvant in the treatment of severe sepsis; however, experience in recipients of solid-organ transplants has not been addressed. The treatments and outcomes of three solid-organ transplant recipients (liver, kidney, and kidney-pancreas) who experienced episodes of severe sepsis are presented and demonstrate initial success with the use of drotrecogin alfa (activated).
