Possible cause of systemic inflammation in patients with chronic heart failure of different classes

Introduction. 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.

Intestinal Microbiocenosis

Aim To study the interrelationship between intensity of chronic systemic inflammation (CSI) with severity of the condition and intestinal microbiocenosis parameters in patients with chronic heart failure (CHF).Material and methods 47 hospitalized patients with symptomatic CHF were evaluated. The following parameters were determined: clinical condition; N-terminal pro-B-type natriuretic peptide (NT-proBNP). C-reactive protein (CRP); serum interleukins (IL) 6 and 10; and intestinal microbiocenosis composition by mass-spectrometry of microbial markers in whole blood. Microbiocenosis indexes were compared in the main group and in 38 outpatient patients with arterial hypertension and ischemic heart disease without CHF.Results Direct, medium-power correlations were found between CRP and IL-6 concentrations and severity of clinical condition (NT-proBNP, ХСН stage, and edema severity) in patients with CHF. Most patients with CHF had lower numbers of bifido-, lacto-, propionic-, and eubacteria, and Clostridium (С.) ramosum and higher numbers of aspergillus. Among CHF patients, the highest indexes of endotoxemia, gram (-) bacteria, cocci, actinomycetes, and microfungi were observed in the group with NT-proBNP from 400 to 2000 pg/ml. Direct correlations were observed for amounts of C. hystolyticum, Pseudonocardia spp., and Aspergillus spp. with IL-6 and IL-10 and unidirectional inverse correlation were observed for these cytokines with Propionibacterium acnes and jensenii, Streptomyces spp., and Nocardia asteroides. In addition, IL-6 concentration was negatively correlated with contents of Staphylococcus aureus, C. difficile, C. ramosum, Eggerthella lenta, and Corynebacterium spp. and was positively correlated with C. propionicum, Moraxella spp. and Flavobacterium spp. Concentration of IL-6 directly correlated with the number of Eubacterium spp. and inversely correlated with numbers of Ruminicoccus spp. and Streptomyces farmamarensis. The amount of Streptomyces farmamarensis negatively correlated with CRP concentrations.Conclusion The study results evidence the significance of intestinal microbial-tissue complex in the pathogenesis of CSI in CHF and allow suggesting this complex as a promising target for therapy.
