Methods A total of 80 patients on MHD, 80 ESRD patients not on dialysis, and 80 healthy controls were enrolled in this study. Serum hepcidin, sTfR and total iron-binding capacity (TIBC) were measured by ELISA. Serum Fe, ferritin (FER) and transferrin (TRF) were measured by routine methods. Data were compared among the groups. Results ① Serum hepcidin and sTfR levels were significantly higher in patients on MHD and ESRD patients not on dialysis than in the healthy controls (P<0.01). ② Serum hepcidin and sTfR were significantly higher in patients on MHD than in ESRD patients not on dialysis (P<0.05). ③ Pearson correlation analysis revealed that serum hepcidin was positively correlated with Scr (r=0.515), hs-CRP (r=0.312), serum Fe (r=0.290) and FER (r=0.286) (all P<0.01); but negatively correlated with HGB (r= -0.466), eGFR (r=-0.362), HCT(r=-0.285), TRF(r=-0.248) and TIBC (r=-0.224) (P<0.05). ④ Pearson correlation analysis revealed that sTfR was positively correlated with HGB (r=0.378) and HCT (r=0.514) (both P<0.01), but negatively correlated with FER (r= -0.764) and TSAT(r=-0.519) (both P<0.01). ⑤ The area of serum hepcidin, sTfR and FER or TSAT under the ROC curve was 90.8%, and the sensitivity and specificity were 93.3% and 77%, respectively. Conclusion Serum hepcidin, sTfR and ferritin or transferrin saturation is important for assessing and treating ESRD patients with renal iron-deficiency anemia
