Abstract

BACKGROUND: Hepcidin-25 is a peptide hormone involved in iron absorption and homeostasis and found at increased serum levels in conditions involving systemic inflammation, renal dysfunction, and increased adiposity. Hepcidin may play a role in the pathogenesis of anemia, but its role in kidney transplantation is undefined. METHODS: This study enrolled 100 stable patients beyond 12 months after transplantation, from a large single United Kingdom center. Serum hepcidin-25 level, and relevant demographic and laboratory data pertinent to posttransplantation anemia, were measured and collected. Independent predictors of serum hepcidin were evaluated, and the relationship between hepcidin and hemoglobin, assessed. RESULTS: Independent associations were seen between higher hepcidin levels and allograft dysfunction (estimated glomerular filtration rate), increased inflammation (high-sensitivity C-reactive peptide), higher transferrin saturation (a marker of iron stores), and the use of marrow-suppressive medication (P
