RESEARCH DESIGN AND METHODS This retrospective cohort study included 455 chronic(More)
BACKGROUND Hepcidin is associated with iron-restricted erythropoiesis. A previous cross-sectional study showed that serum hepcidin-25 levels are negatively associated with the hemoglobin concentration in non-dialysis chronic kidney disease (CKD) patients with sufficient iron stores. This longitudinal study aimed at ascertaining the association between(More)

An 80-year-old woman positive for myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) was admitted with a 3-month history of fever, general malaise, and weight loss, after unsuccessful treatment with antibiotics. Upon admission, her fever persisted, and there was concomitant deterioration of renal function without active urine sediments.(More)
