    ABSTRACT: The use of kidneys from donors at increased risk for viral infections (DIRVI) such as HIV could increase the number of transplants and decrease waiting times. This study aimed to identify the proportion of kidney transplant candidates that would accept a kidney from a DIRVI and the factors that influenced this decision. Conjoint analysis was used to assess the conditions in which renal transplant candidates would accept a DIRVI kidney. Candidates completed 12 scenarios in which the waiting time for a kidney, the donor age as a surrogate for kidney quality, and the risk of contracting HIV were systematically varied. Among 175 respondents, 42 (24.0%) rejected DIRVI kidneys under all conditions, 103 (58.9%) accepted DIRVI kidneys under some conditions, and 31 (17.7%) always accepted DIRVI kidneys. In multivariable logistic regression, patients were more likely to accept a DIRVI kidney when waiting time was longer, the donor was younger, and HIV risk was lower (P < 0.01 for each variable). Patients on dialysis (P < 0.01) and older patients (P = 0.04) more commonly accepted DIRVI kidneys, but self-rated sense of health was not associated with DIRVI kidney acceptance. Most renal transplant candidates would accept a DIRVI kidney under some circumstances. These findings suggest that recipients can be allowed to make prospective choices regarding DIRVI kidney acceptance without hindering placement of these organs.

    ABSTRACT: Contrast-induced nephropathy continues to be a common cause of in-hospital acute kidney injury. Published studies on pathogenesis, clinical significance, diagnosis, and preventive measures have dramatically increased significantly in the past several years. This review will focus on new developments in contrast-induced nephropathy. Studies on the clinical significance of contrast-induced nephropathy are reviewed along with initial reports of biomarkers in diagnosing this complication of iodinated contrast administration. Emerging literature on the relative nephrotoxicity of iso-osmolar versus low-osmolar contrast media and the value of bicarbonate hydration are discussed. More recent preventive measures using prostacyclin, 'statins', and erythropoietin are also reviewed. Contrast-induced nephropathy is an increasing cause of acute kidney injury and is associated with significant mortality and morbidity. Future developments in this field will focus on refining the clinical significance of this complication, earlier diagnosis with biomarkers, clarifying the role for bicarbonate and iso-osmolar contrast agents as preventive strategies, and the introduction of new prophylactic techniques on the basis of an improved understanding of pathogenesis at the cellular level.
