Introduction. Pathologies of thyroid dysfunction associated with iodine deficiency remain one of the urgent problems throughout the world and are mainly associated with natural iodine deficiency in places where about 30% of the world’s population lives.Objective. Study of the dynamics of thyroid hormones in infants born from mothers with diffuse endemic goiter.Materials and methods. A retrospective study of 68 infants from mothers with diffuse endemic goiter (DEG) was carried out. Research methods included: analysis of anamnestic data, palpation, and ultrasound in mothers, with a study of the level of thyroid hormone in newborns and parturient women.Results. Infants from mothers with DEG have characteristic changes in the level of thyroid hormones in the blood, in particular, in the cord blood, the level of thyroid-stimulating hormone (TSH) is 22.4% higher than in the control group (p < 0.05). The difference between free triiodothyronine (T3) and thyroxine (T4) is on average lower by 8.6% and 4.3%, respectively, (p < 0.05 and p < 0.1). On the 3rd day of life, these fluctuations persist, and the level of TSH in the peripheral blood exceeded up to 20.9%, but there were no pronounced clinical signs of congenital pathology associated with the thyroid gland. At the same time, in the first months of life in infants, there is a lag in weight gain by an average of 9.6% about practically healthy newborns.Conclusion. In infants born to mothers with DEG, there is an increase in the umbilical blood level of TSH up to 22.4% about practically healthy newborns, with a simultaneous decrease in T4 to 4.3%, T3 to 8.6%, without pronounced clinical signs of congenital pathology. In these children, in the first months of life, there is a lag in physiological weight gain of up to 9.6%, which should be taken into account when managing children in an outpatient setting.
A review article is devoted to the analysis of scientific and literary data published over the past 10 years, devoted to the problem of studying the role of Helicobacter pylori in the development of iron deficiency anaemia in children and adolescents. Comparative data of domestic and foreign scientists on the mechanism of exposure of Helicobacter pylori (НР) to the pathogenesis of resistant iron deficiency anaemia in children are given.It was determined that the development of iron deficiency anaemia in children with HP infection is influenced by many mechanisms, therefore, in the treatment of children with this pathology, the appointment of anti- HP bacterial therapy with ferrotherapy, taking into account age-related characteristics and needs, is justified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
