A multidisciplinary group of researchers and clinicians met in October 2018 to identify evidence and address controversies in potassium management. Here we provide our overview of potassium homeostasis in health and disease and guidance for evaluation and management of dyskalemias in the context of kidney diseases, and indicate research priorities.

Before the introduction of erythropoiesis-stimulating agents (ESAs) in 1989, repeated transfusions given to patients with end-stage renal disease caused iron overload, and the need for supplemental iron was rare. However, with the widespread introduction of ESAs, it was recognized that supplemental iron was necessary to optimize hemoglobin response and allow reduction of the ESA dose for economic reasons and recent concerns about ESA safety. Iron supplementation was also found to be more efficacious via intravenous compared to oral administration, and the use of intravenous iron has escalated in recent years. The safety of various iron compounds has been of theoretical concern due to their potential to induce iron overload, oxidative stress, hypersensitivity reactions, and a permissive environment for infectious processes. Therefore, an expert group was convened to assess the benefits and risks of parenteral iron, and to provide strategies for its optimal use while mitigating the risk for acute reactions and other adverse effects.

I n 2012, Kidney Disease: Improving Global Outcomes (KDIGO) published a guideline on the classification and management of acute kidney injury (AKI). 1 Since then, new evidence has emerged that has important implications for clinical practice. Large epidemiology studies and risk profiles for AKI have become available in adults and children, such as the AKI-Epidemiologic Prospective Investigation (AKI-EPI) study, 2 the 0by25 Initiative, 3 the Southeast Asia-AKI (SEA-AKI) study, 4 and the Assessment of Worldwide Acute Kidney Injury, Renal Angina, and Epidemiology (AWARE) 5 and Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) 6 studies. The effectiveness of the KDIGO recommendations in preventing AKI has been confirmed in small single-center randomized controlled trials (RCTs), such as the Prevention of AKI (PrevAKI) 7 and the
