The associations of cytokines and gens polymorphisms of ß-adrenoceptors in patients with heart failure and some thyroid pathology (literature review and own observations).

ABSTRACT

OBJECTIVE: Aim: To analyze the role of cytokines in the progression of heart failure (HF) in patients with concomitant pathology of the thyroid gland. PATIENTS AND METHODS: Materials and Methods: The systematization of literature data on the role of cytokines in the progression of HF in patients with concomitant thyroid pathology (TP) was carried out. The results of our own research were presented. CONCLUSION: Conclusions: The final chapter in the history of the role of cytokines in the progression of HF has not yet been written. Further studies, including genetic ones, are necessary. The patients with HF have higher levels of TNFß and IL-6, and a lower concentration of IL-4, compared to the control group. Patients with a fatal outcome of the disease, in contrast to those who survived for two years, have an increased level of TNFß. In patients with concomitant TP, who had repeated hospitalization, a lower level was registered, compared to that under conditions of a more favorable course of heart failure. Concentrations of cytokines in the blood of patients with HF are associated with gene polymorphisms of the ß-adrenoreceptor system the C-allele of the Gly389A polymorphism of the ß1-adrenoceptor gene leads to a decrease in the risk of increasing TNFα; IL-1α increases in the presence of the A-allele of the Ser49Gly polymorphism of this gene. In patients with HF and concomitant thyroid pathology, the risk of IL-6 growth increases in homozygous (C) patients for the Ser275 polymorphism of the ß3 subunit of the G-protein.
