Correlation between hepcidin level and iron, mineral metabolism in maintenance hemodialysis patients / 中国医师进修杂志

Objective To investigate the correlation between serum hepcidin level and iron, mineral metabolism in maintenance hemodialysis (MHD) patients. Methods Seventy-five MHD patients were selected. The serum hepcidin, serum iron and mineral metabolism indexes were detected by enzyme-linked immunosorbent double antibody sandwich method, and their correlation was analyzed. Results The level of serum hepcidin in 75 MHD patients was 87- 264 μg/L. The patients were divided into 3 groups according to serum hepcidin level. In group A, the serum hepcidin level of 26 cases was＜120 μg/L; in group B, the serum hepcidin level of 24 cases was 120- 200 μg/L; in group C, the serum hepcidin level of 25 cases was>200 μg/L. There were no significant differences in age, gender, albumin and serum calcium among 3 groups (P > 0.05). The levels of ferritin, transferrin saturation (TS), serum phosphorus and parathyroid hormone (PTH) increased in the 3 groups as the hepcidin level increased, while hemoglobin, serum iron, total iron binding capacity (TIBC), and 25 hydroxy vitamin D decreased significantly, and there were statistical differences (P＜0.05). The Pearson correlation analysis result showed that serum hepcidin was positively correlated with ferritin, PTH, serum phosphorus (r = 0.862, 0.536 and 0.320; P＜0.01); and serum hepcidin was negative correlation with serum iron, TIBC, hemoglobin, 25 hydroxy vitamin D (r=-0.358,-0.270,-0.284 and-0.614; P＜0.01); but there was no correlation between serum hepcidin and albumin and serum calcium (r=0.018 and-0.005, P＞0.05). Conclusions The serum hepcidin level in MHD patients is closely related to iron and mineral metabolism.
