Peculiarities of syntropic functional disorders of the digestive system against the ground of connective tissue dysplasia

A considerable occurrence of functional gastrointestinal disorders (FGID) in childhood, their frequent combination between themselves, the risk of transformation into organic pathology together with high collagen content in the digestive organs require investigation of pathophysiological relations of the pathology with collagen dysfunction. Objective of the study is to investigate the role of collagen disorders in FGID pathophysiology and assess their effect on clinical development of irritable bowel syndrome. 63 children suffering from FGID have been examined. Irritable bowel syndrome was diagnosed as a leading functional disorder of all the children examined. Syntropic functional biliary disorders were found in (38,46±6,13) % patients. By the results of molecular-genetic examination genetic polymorphism of COL3A1 rs1800255 with prevailing the genotype G/А – 47,62 % (95 % CІ 35,04 – 60,2) was determined, that was most reliably found (р = 0,008) in children with syntropic functional biliary disorders and was associated with a wide range of comorbid pathology (р = 0,002) and pronounced dysplastic signs (р = 0,034)
