Clinical and Anamnestic Features of Pathology of Gastrointestinal Tract in Children with Syndrome of Heart Connective Tissue Dysplasia, Born to Parents Irradiated In Childhood due to the Chernobyl Accident

The children born to parents irradiation-exposed in childhood due to the Chernobyl accident were found to have mainly the upper gastrointestinal pathology, namely chronic gastroduodenitis, usually concomitant, and several areas of the alimentary canal being involved into the pathological process. The children with the syndrome of heart connective tissue dysplasia have earlier manifestation of the upper gastrointestinal diseases (from pre-school age) and with age systemic damage of various organs and systems is noted, as evidenced by such indicators as a number of clinical entities per child (among the children of the I group — 6.8; II group — 4.9). The analysis of biomedical risk factors and index of burdened familial history on gastrointestinal pathology in I–II degree relatives did not demonstrate a significant difference between the groups. The clinical manifestations of chronic upper gastroduodenal diseases in children with the syndrome of heart connective tissue dysplasia typically have more frequent exacerbations due to the psycho-emotional and physical exhaustion. These children more often have moderate periodic pain; higher occurence of gastric dyspepsia symptoms, intestinal motor dysfunction and concomitant nervous system disorders (80.0 %) and chronic foci of infection (62.2 %)
