PARASITIC INFECTIONS AS A CAUSE OF FUNCTIONAL ORGAN DISORDERS IN CHILDREN

Abstract

Annotation: Parasitic diseases continue to represent a significant problem in modern medicine and public health. They are pathological conditions that develop due to the activity of helminths and protozoan microorganisms inhabiting the human body. The nature of interaction between the parasite and the host largely determines the clinical presentation, severity, and duration of the disease. The invasion and prolonged persistence of parasites in different organs and tissues can lead to a wide range of clinical manifestations. These symptoms are mainly associated with the mechanical influence of parasites on host tissues, their metabolic and secretory products, as well as the development of toxic-allergic and immunopathological reactions. Mechanical effects may include obstruction of ducts or vessels, irritation of tissues, and impairment of normal organ functions. At the same time, parasite-derived metabolites and antigens are capable of triggering inflammatory processes and disrupting normal immune regulation.
