FUNCTIONAL STATE OF THE THYROID IN CONDITIONS OF IODINE DEFICIENCY IN CHILDREN WITH DISORDERS OF THE VEGETATIVE NERVOUS SYSTEM

A study was carried out to study the functional state of the thyroid gland in children with syndrome vegetative dysfunction (SVD) under conditions of iodine deficiency and to find out the significance of the obtained parameters in the manifestation of various clinical forms of the disease. The study included 120 children aged 1115 years and 25 healthy children of the same age. The surveyed were divided into 2 groups: the 1st group included 65 children with SVD against the background of iodine deficiency (main group), the 2nd group included 55 patients with SVD who had no signs of iodine deficiency (control group). It was revealed that patients with decreased thyroid function, in contrast to patients with normal, one had a more severe course and marked clinical symptoms of the disease. According to ECGdata, deeper violations of the function of automatism and conduction functions were revealed, according to Echocardiography (EchoCG) data, a decrease in motor activity of the left ventricular myocardium. Cardiointervalography (CIG) showed that in patients with impaired thyroid functional state there was a vagotonic type of initial vegetative tone IVT, vegetative reactivity was reduced, and vegetative provision was clearly insufficient.
