ReviewThe kidney effects of hematopoietic stem cell transplantation.
Hematopoietic stem cell transplant (HSCT) patients are at risk for acute kidney disease and CKD, which confer excess morbidity and mortality in this patient population. A main cause of acute kidney injury (AKI) in stem cell recipients is prerenal azotemia, but acute tubular necrosis (ATN), obstruction, marrow transfusion toxicity, and hepatic sinusoidal obstruction syndrome also contribute. ⋯ For most patients, the exact etiology of CKD is never identified, but graft vs host disease and thrombotic microangiopathy are important diagnoses to consider. Stem cell transplant patient survival on dialysis is generally poor, but kidney transplantation is a safe and reasonable option for HSCT recipients who progress to ESRD.

Tumor lysis syndrome (TLS) is an oncologic emergency triggered by the rapid release of intracellular material from lysing malignant cells. Most common in rapidly growing hematologic malignancies, TLS has been reported in virtually every cancer type. ⋯ Prevention of TLS may be more effective than treatment, and identification of at-risk individuals in whom to target preventative efforts remains a key research area. Herein, we discuss the pathophysiology, epidemiology, and treatment of TLS with an emphasis on the kidney manifestations of the disease.

ReviewEducation for patients with progressive CKD and acute-start dialysis.
For individuals living with CKD and those who have been discovered to have ESRD, the decisions facing them can be daunting. Such decisions include having renal replacement therapy (RRT) or conservative care, having a kidney transplant, or selecting a modality of dialysis that would fit their lifestyle and values. ⋯ We also present an approach to educate and support those who have urgently started dialysis and require chronic RRT. This educational model has its basis in theories of education and decision-making and has been used with success in this population.
