. Anemic syndrome (AS) is a common pathological condition in patients with chronic heart failure (CHF) and is recognized as an independent predictor of poor prognosis. A particular role is played by pathogenetically associated with CHF anemia. Mechanisms of its occurrence are being studied. An important role belongs to systemic inflammation, which is involved in the pathogenesis of anemia of chronic diseases (ACD). However, the contribution of cytokine-induced inflammation in patients with heart failure has not yet been fully investigated. Material and methods. A total of 873 cases of patients with CHF were prospectively analyzed on the basis of the cardiology department of the SBHCI NNR «Nizhny Novgorod Regional Clinical Hospital n.a. N.A. Semashko». The main group consisted of patients with anemia pathogenetically associated with heart failure (n = 96), the control group (CG) (n = 35) patients with heart failure without anemia. The indicators of ferrokinetics were assessed and the systemic inflammation was compared by indicators of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and serum hepсidin. Results. Patients of the main group had signs of functional iron deficiency (ID) and significantly higher values of cytokines and hepsidin compared with the CG. The relationship between the level of cytokines and hepsidin with the severity of CHF, hemogobin and chronic kidney disease was revealed. Conclusion. An increase in the concentration of pro-inflammatory cytokines and hepcidin in patients with AS with decompensation of CHF is interrelated with functional ID and a decrease in hemoglobin level. This shows the role of cytokine-induced inflammation in the genesis of anemia in heart failure. The functional state of the kidneys makes a special contribution to these mechanisms. As CKD increases, the levels of inflammatory cytokines and hepcidin in these patients and their relationship with markers (CKD) increase.
