Iron plays a detrimental role in the intracerebral hemorrhage (ICH)-induced brain damage, while hepcidin is the most important iron-regulated hormone. Here, we investigate the association between serum hepcidin and serum iron, outcome in patients with ICH. Serum samples of 81 cases with ICH were obtained on consecutive days to detect the levels of hepcidin, iron, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The National Institutes of Health Stroke Scale score (NIHSS) was measured at admission and on days 7 and 30, and the modified Rankin Scale (mRS) score was evaluated at 3 months after ICH. Additionally, the correlations of serum hepcidin with serum iron and the mRS score were analyzed by a generalized linear model. Higher serum hepcidin levels were detected in patients with poor outcomes (P < 0.001), and the mRS score increased by a mean of 1.135 points (95% CI 1.021-1.247, P < 0.001) for every serum hepcidin quartile after adjusting for other prognostic variables. Pearson correlation analysis showed that serum hepcidin was negatively correlated with serum iron (r = -0.5301, P < 0.001), and a significantly lower concentration of serum iron was found in patients with poor outcomes (P = 0.007). Additionally, serum hepcidin was independently correlated with mRS scores of ICH patients (OR 1.115, 95% CI 0.995-1.249, P = 0.021). Our results suggest that serum hepcidin is closely related to the outcome of patients with ICH and may be a biological marker for outcome prediction. [ABSTRACT FROM AUTHOR]
