ALLERGIC REACTIONS ON THE BACKGROUND OF CONGENITAL HEART DEFECTS IN YOUNG CHILDREN

Аннотация

Congenital heart defects (CHDs) are an important problem in pediatrics due to their high prevalence and the need for early surgical correction due to significant health problems and disability in children. according to who, CHD occurs in 0.7-1.7% of newborns. In some cases, the rapid progression of the stages of the course of congenital heart disease is determined not only by its severity, but also by the influence of pathological conditions. Currently, allergies are among the most common pathological conditions in children. According to epidemiological studies, up to 25% of children suffer from allergic reactions (AR). This puts forward the problem of allergic pathology to one of the first places in modern pediatrics. Over the past two decades, there has been an upward trend in the prevalence of AR in childhood. In their development, an important role belongs to the interaction of genetic and environmental factors with the subsequent development of sensitization of the body, but in general, the direct causes of the increase in the prevalence of AR remain insufficiently clear. Epidemiological studies conducted in many countries have shown that a high prevalence of allergic pathology is associated with a Western lifestyle, urbanization, environmental pollution with chemical compounds, and a high socioeconomic status.
