MORPHOLOGICAL TRAITS OF A CHRONIC GASTRODUODENITIS AT PRESCHOOLERS WITH VARIOUS AMYLOLYTIC ACTIVITY OF THE MIXED SALIVA

Abstract

Background: The aim of the study was to to estimate traits of the morphofunctional changes of a gastroduodenal mucous membrane at chronic inflammatory diseases of the upper digestive tract at preschoolers with various level of amylolytic activity of saliva. Patients and methods: 145 children at the age of 3–7 years with chronic inflammatory diseases of a stomach and duodenum are surveyed. The amylolytic activity of the mixed saliva by Smith-Roy-Ugolev amylolytic method was determined at patients. 2 clinical groups with account of median (the 50th percentile) distribution of amylolytic activity of saliva are created: the first — with indicators below the median (n =72), the second — with indicators above or equal to the median (n =73). The endoscopic research (all children), histological research bioptates (n =63), morphometric analysis of a duodenum mucous membrane (n =26) were applied for the purpose of assessment of a morphofunctional condition of a stomach and duodenum. Results: It is established that predominant duodenum involvement, high frequency of isolated duodenitis, subatrophic and dystrophic changes of a duodenal mucous membrane, bigger intensity and depth of inflammatory process against lower level of nonspecific tissue protection, existence of signs of an allergic inflammation are characteristic for patients with low amylolytic activity of saliva. Conclusion: Determination of amylolytic activity of the mixed saliva at children with inflammatory diseases of a stomach and duodenum is available, noninvasive informative diagnostic test orienting in assessment of a character and extent of involvement of a gastroduodenal mucous membrane and allowing in due time to reveal the patients needing the profound inspection of gastroduodenal area and also to exclude food allergy.
