Aim. To study the role of hepcidin as a regulator of iron metabolism and a mediator of inflammation in elderly and senile patients with chronic heart failure (CHF) with anemia of chronic diseases (ACD).Material and methods. The levels of hemogram parameters, ferrokinetics (serum iron, ferritin, transferrin, erythropoietin, hepcidin), inflammation [C-reactive protein (CRP), interleukin-6 (IL-6)], as well as correlations between hepcidin and these parameters were studied in patients with CHF with ACD (n=35), with CHF without anemia (n=35) and in elderly and senile patients without CHF and anemia (control group; n=20).Results. Normal levels of hepcidin (9.17±0.97 ng/ml) and the only significant correlation of hepcidin with the ferrokinetic parameter – serum iron [r(S)=0.480, p<0.05] were found in the control group. Normal levels of hepcidin (12.01±1.19 ng/ml) and two significant correlations of hepcidin with the ferrokinetic parameter – ferritin [r(S)=0.525, p<0.05] and transferrin [r(S)=-0.343, p<0.05] were found in the CHF without anemia group. Significantly elevated levels of hepcidin (23.81±3.63 ng/ml) were found in the CHF with ACD group compared to the CHF without anemia group (p=0.008) and the control group (p=0.003). Also, five significant correlations of hepcidin with hemogram parameters – hemoglobin [r(S)=-0.461, p<0.05] and the average concentration of hemoglobin in the erythrocyte [r(S)=-0.437, p<0.05]; with ferrokinetic parameters – ferritin [r(S)=0.596,p<0.05] and transferrin [r(S)=-0.474, p<0.05]; with inflammation parameters – CRP [r(S)=0.561, p<0.05] were found in the CHF with ACD group.Conclusion. The increased level of hepcidin in CHF patients with ACD and the formation of links of hepcidin with indicators of inflammation reflect its role as a mediator of inflammation, and the formation of connections with indicators of hemogram and ferrokinetics – its role as a regulator of iron metabolism involved in the development of ACD in elderly and senile CHF patients.
