| Abstract: | The serum levels of hepcidin generally increase in patients with chronic kidney disease (CKD) due to inflammation or a decline in the glomerular filtration rate. However, the differences in the ferrokinetics among dialysis modalities are unclear. We investigated the relationship between serum levels of hepcidin and ferritin among non‐dialyzed CKD (ND), hemodialysis (HD), and peritoneal dialysis (PD) patients. We recruited 285 CKD patients (117 ND, 80 HD, and 88 PD patients) and measured the serum levels of hepcidin‐25, ferritin, hemoglobin, iron, transferrin saturation (TSAT), albumin, and high sensitivity C‐reactive protein (hs‐CRP). Hepcidin‐25 levels were elevated in all CKD patients and were significantly higher in PD than in ND and HD patients. The hepcidin/ferritin ratio was significantly higher in PD patients independent of TSAT, hemoglobin, hs‐CRP, and serum albumin. Hepcidin/ferritin ratio, associated with both dialysis modality and inflammation, is expected to be a useful indicator of anemia in CKD. |
