ROLE OF CYTOKINE ACTIVATION IN THE DEVELOPMENT OF CARDIOVASCULARDISORDERS IN PATIENT WITH GRAVES DISEASE AND CHRONIC HEART FAILURE
The aim of the study is to assess the ability to influence immunological changes on the formation of cardiovascular complications of hyperthyroidism by determining the level of thyrotropin-receptor antibodies (TRAb), 6,8,10 interleukins (IL-6,8,10) and tumor necrosis factor-alpha (TNF-) in patients with Graves’ disease (Gd) and chronic heart failure (CHF) and without it. 68 patients were investigated with Gd, CHF diagnosed in 38 patients (55.9%), stage 1- in 12 patients (31.6%), stage 2A - in 19 (50%) patients, stage 2B - in 7 (18,4%) patients. For the analysis, patients were divided into 3 groups: 1 - with no signs of heart failure, 2 with CHF 1 stage (because the clinical signs characteristic of heart failure stage 1 can also be symptoms of hyperthyroidism, these patients were in separate group), 3 - CHF 2A and step 2B. In all three patients groups showed a significant increase in the levels of cytokines and TRAb compared with the control group. The development of CHF in patients with Graves’ disease is associated with increasing of IL-6, IL-8 and IL-10 concentration. direct correlation between the level of TRAb, TNF- and development of the cardiovascular complications in patients with Gd have not been identified.
