ReviewComparing mandated health care reforms: the Affordable Care Act, accountable care organizations, and the Medicare ESRD program.
In addition to extending health insurance coverage, the Affordable Care Act of 2010 aims to improve quality of care and contain costs. To this end, the act allowed introduction of bundled payments for a range of services, proposed the creation of accountable care organizations (ACOs), and established the Centers for Medicare and Medicaid Innovation to test new care delivery and payment models. The ACO program began April 1, 2012, along with demonstration projects for bundled payments for episodes of care in Medicaid. ⋯ Nephrologists are in a position to assure that the ACO development will benefit from the ESRD experience. This article reviews the new ESRD payment system and the Quality Incentive Program, comparing and contrasting them with ACOs. Better understanding of similarities and differences between the ESRD program and the ACO program will allow the nephrology community to have a more influential voice in shaping the future of health care delivery in the United States.

Randomized Controlled TrialEffect of high-dose erythropoietin on graft function after kidney transplantation: a randomized, double-blind clinical trial.
Delayed graft function (DGF) is associated with adverse long-term outcomes after deceased-donor kidney (DDK) transplantation. Ischemia-reperfusion injury plays a crucial role in the development of DGF. On the basis of promising animal data, this study evaluated any potential benefits of erythropoietin-alfa (EPO-α) given intra-arterially at the time of reperfusion of renal allograft on the degree of allograft function, as well as tubular cell injury measured by urinary biomarkers in the early post-transplant period. ⋯ This study did not show any clinically demonstrable beneficial effects of high-dose EPO-α given intra-arterially during the early reperfusion phase in DDK transplant recipients in terms of reducing the incidence of DGF or improving short-term allograft function.

Randomized Controlled Trial25-Hydroxyvitamin D response to cholecalciferol supplementation in hemodialysis.
Recent understanding of extrarenal production of calcitriol has led to the exploration of native vitamin D treatment in dialysis patients. This paper reports the pharmacokinetics of 25-hydroxyvitamin D response to 10,333 IU cholecalciferol given weekly in subjects on chronic dialysis. ⋯ Cholecalciferol (10,333 IU) given weekly in patients on chronic hemodialysis produces a steady state in 25-hydroxyvitamin D of approximately 24 ng/ml.

Complete adenine phosphoribosyltransferase (APRT) deficiency is a rare inherited metabolic disorder that leads to the formation and hyperexcretion of 2,8-dihydroxyadenine (DHA) into urine. The low solubility of DHA results in precipitation of this compound and the formation of urinary crystals and stones. The disease can present as recurrent urolithiasis or nephropathy secondary to crystal precipitation into renal parenchyma (DHA nephropathy). ⋯ However, the disease can present at any age, and the variability of symptoms can present a diagnostic challenge to many physicians. The early recognition and treatment of APRT deficiency are of crucial importance for preventing irreversible loss of renal function, which still occurs in a non-negligible proportion of cases. This review summarizes the genetic and metabolic mechanisms underlying stone formation and renal disease, along with the diagnosis and management of APRT deficiency.

Case ReportsTo dialyze or not: the patient with metastatic cancer and AKI in the intensive care unit.
AKI severe enough to necessitate renal replacement therapy occurs in approximately 5% of patients admitted to the intensive care unit (ICU) and is associated with in-hospital mortality in excess of 50%. Complicating factors, such as cancer, can increase in-hospital mortality to 85%. ⋯ Woven into the discussion are insights from the clinical and ethics literature on this topic, along with the experience of the author. This Attending Rounds presents an approach to deciding when it is not appropriate to dialyze patients with AKI in the ICU.
