Background: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. Aim: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF. Material and methods: We examined 65 elderly and very old patients with ischemic heart disease (IHD) (35 with CHF and ACD, 10 with CHF and IDA, 20 without CHF, ACD, and IDA [control group]). H level in blood serum was measured using competitive solid-phase immunoenzyme assay. Results and discussion: In patients with CHF and ACD mean H levels were significantly high relative to those in patients with CHF and IDA, while in the latter group H levels were insignificantly low relative to those in patients of control group. High H level, high level of inflammatory tests as well as positive correlations between them, and negative correlation between H and hemoglobin (Hb) are indicative of inflammation as a cause of H level elevation, which in turn facilitates development of anemia in elderly and very old patients with CHF and ACD. Low H level, normal levels of inflammatory tests, absence of links between them, as well as absence of correlation between H and Hb are indicative of lack of H role in development of anemia in these patients with CHF and IDA. We did not study influence on development of anemia of each of possible causes (inflammation, decompensation of CHF) separately, therefore contribution of each of them is unknown. The data obtained also do not exclude effect of other not investigated in this work and presently unknown factors. Received by us data indicate to necessity of precise identification of origin of anemia in every case in an elderly or very old patient with CHF with the aim of elimination of its cause and conduct of pathogenetically valid therapy.

To perform a comparative analysis of anemia of chronic disease (ACD) and iron-deficiency anemia (IDA) in late middle-aged and elderly patients with chronic heart failure (CHF) by ferrokinetic parameters, inflammation indexes, and their associations. Materials and methods. 65 patients with ischemic heart disease were evaluated, including 35 patients with CHF and ACD, 10 patients with CHF and IDA, and 20 patients without CHF, ACD, and IDA (control group, CG). Results. Patients with CHF and IDA had true iron deficiency whereas 54% of patients with CHF and ACD had functional iron deficiency, and 46% of patients had no iron deficiency. Levels of acute phase proteins, ferritin and hepcidin, C-reactive protein (CRP), and interIeukin-6 (IL-6) were highly sig-nificantly different in patients with CHF and ACD and patients with CHF and IDA; positive and significant correlations were found for levels of IL-6 and ferritin, IL-6 and CRP, and CRP and hepcidin. In patients with CHF and IDA, levels of acute phase proteins, ferritin and hepcidin, CRP, and IL-6 were low and correlations of IL-6 with ferritin, IL-6 with CRP, and CRP with hepcidin were non-significant. Concentrations of erythropoietin were significantly higher in patients with CHF and ACD and patients with CHF and IDA compared to the control group; however, significant differences between them were absent.

To compare the efficacy of prophylactic administration of mineral-vitamin complexes "Feroglobin-B12" and "Complivit iron" with different degrees of Fe valence. Materials and methods. 120 female subjects were examined. To determine the quality of life, the SF-36 questionnaire was used. The presence of anxiety was determined on the Spielberger-Khanin Alarm Scale. 30 women with a deficit of Fe were divided into 2 groups of 15 people each. The first group received "Ferroglobin-B12", the second – "Complivit iron" for a month. Results. In a month after the initiation of preventive therapy in women of the 1 group the content of Fe serum was normalized. In the second group, its concentration approached the control values. The difference in Fe content in the 1 and 2 groups was of a reliable nature. Conclusion. The intake of "Ferroglobin-B12" was not accompanied by side effects, and performance indicators, social activity and mental health reached control values, unlike the group of patients taking Complivit iron.
