Background: Iron is an essential element for the living body. It is well known that iron homeostasis disorders are important in two ways - its deficiency and its overload lead to several pathologies.
Methods: We measured 17 patients with iron deficiency anemia (IDA); 19 with anemia of chronic diseases (ACD); 15 with ischemic stroke (IS). The results were compared to a previously selected control group. For evaluation of iron metabolism status, we measured serum iron levels, ferritin, and soluble transferrin receptors. For inflammation, serum interleukin-6 and hsCRP were measured. Serum hepcidin quantification was performed using a previously validated immunosorbent method. Ferritin was measured by an ECLIA method; serum iron on AAS; hsCRP using a nephelometric analysis.
Results: We found statistically significant elevated serum hepcidin levels in patients with ACD and IS compared to the control group (p < 0.001). Patients with IDA had statistically significant lower hepcidin levels compared to the control group (p < 0.001). Serum ferritin levels in the IS group was higher compared to the control and other groups (p < 0.001). The lowest ferritin concentrations were established in the IDA group compared to the control (p < 0.001). We found a strong correlation between serum hepcidin and ferritin levels in the IS group (r = 0.583; p < 0.001).
Conclusions: Quantification of serum hepcidin levels might be used as a link for prediction of acute ischemic stroke and future therapeutic influences.
