- In chronic kidney disease (CKD), anemia and disordered iron homeostasis are prevalent and associated with significant adverse consequences. In 2012, Kidney Disease: Improving Global Outcomes (KDIGO) issued an anemia guideline for managing the diagnosis, evaluation, and treatment of anemia in CKD. Since then, new data have accrued from basic research, epidemiological studies, and randomized trials that warrant a re-examination of previous recommendations. Therefore, in 2019, KDIGO decided to convene two Controversies Conferences to review the latest evidence, explore new and ongoing controversies, assess change implications for the current KDIGO anemia guideline, and propose a research agenda. The first conference, described here, focused mainly on iron-related issues, including the contribution of disordered iron homeostasis to the anemia of CKD, diagnostic challenges, available and emerging iron therapies, treatment targets, and patient outcomes. The second conference will discuss issues more specifically related to erythropoiesis-stimulating agents, including epoetins and hypoxia-inducible factor-prolyl hydroxylase inhibitors (HIF-PHIs). Here we provide a concise overview of the consensus points and controversies resulting from the first conference and prioritize key questions which need to be answered by future research.

- BACKGROUND: The diagnostic use of hepcidin is limited by the absence of standardization and lack of age-specific reference ranges in children in particular. The aim of this study was to determine reference ranges of serum hepcidin in healthy children aged 0.5-3 y using mass spectometry (MS) and a commercial immunochemical (IC) assay, and to investigate its association with other indicators of iron status and inflammation. METHODS: We included 400 healthy children aged 0.5-3 y. We constructed reference ranges for MS-hepcidin and IC-hepcidin concentrations using the median, P2.5, and P97.5 in a normative population of 219 children with no anemia, no infection and/or inflammation, and no iron deficiency. RESULTS: Median concentrations (P2.5-P97.5) of MS-hepcidin and IC-hepcidin were 3.6 nmol/l (0.6-13.9 nmol/l) and 7.9 nmol/l (1.9-28.6 nmol/l), respectively. We found a good correlation between both methods. However, MS-hepcidin was consistently lower than IC-hepcidin. Hepcidin correlated with ferritin and C-reactive protein. CONCLUSION: We provide reference ranges for hepcidin for an MS and commercial IC method. Absolute values between assays differed significantly, but hepcidin concentrations obtained by MS and IC methods correlate with each other, and both correlate with ferritin and CRP.
