CLINICAL AND IMMUNOLOGICAL CHARACTERISTICS OF CHRONIC GASTRODUODENAL PATHOLOGY IN CHILDREN WITH FOOD ALLERGY
Today, despite the large number of research reports on food allergy, there are some issues associated with its systemic character and complicated diagnosis that requiring in-depth study of this condition. The factors to be elucidated and studied in greater detail include etiologically significant risk factors for food allergy as well as the complex immunological pathogenetic mechanisms of its development. Thus, the aim of our work was to investigate the immunological status of children with inflammatory diseases of the upper gastrointestinal tract, who had a history of food allergies. Materials and methods. The study included 34 children aged 6 – 15 years with gastroduodenal pathology and food allergy manifestations, whose parents voluntarily consented to their participating in the research. All children underwent a comprehensive allergic and immunological examination. Results and discussion. The distribution of children with gastroduodenal pathology, who had a history of allergic response when consuming food, by immunoglobulin E level, was almost uniform. Analysis of cytokine status has shown a prevalence of pro-inflammatory cytokine - interleukin-4 in more than half (56.3%) of the patients with IgE-mediated allergic reactions to food vs. 38.9% of children in the comparison group. Over the study, it has been found out that elevated levels of the thymus-associated regulatory chemokine - TARC / CCL17 made up 38.3% of the total number of subjects. Conclusion. The results of the study point out the persistence of food allergic manifestations in children with chronic gastroduodenal pathology, regardless of IgE or non-IgE mediated reactions that has been confirmed by the presence of allergic inflammatory markers as interleukin-4 and TARC / CCL-17 chemokine in the deficiency of anti-inflammatory cytokine interleukin-10, which in turn necessitates the thorough monitoring of the cases and implementation of elimination measures into clinical protocols for managing this group of patients.
