[The microbiocenosis of upper parts of digestive tract of children with gastroesophageal reflux disease and chronic gastroduodenitis]

The article considers the microbe specter of mucous coat of esophagus and stomach in children with gastro esophageal reflux disease and chronic gastroduodenitis. In patients with diseases of upper parts of digestive tract, the opportunistic pathogenic bacteria are isolated more often and their strains have aggression factors and cytotoxicity. In children with reflux disease the microbe landscape of esophagus is larger both in numerical and specific respect as compared to healthy adolescents and children with isolated gastroduodenitis.

[Colonic microenvironment in familial helicobacter infection]

To elucidate the significance of the familial microenvironment in the genesis of Helicobacter infection, a clinical and instrumental investigation was made of 13 families selected by the probands who had digestive diseases associated with H. pylori: gastroduodenitis and duodenal ulcer disease. The occurrence of Helicobacter infection and gastritis in the family members was ascertained to be largely determined by their concurrent residence in the limited area, i.e. by the way of life. The contribution of the "family" factor in antral gastritis, fundal gastritis, and H. pylori infection was 60.0, 40.0, and about 90.0%, respectively. The patients with gastroenterological abnormalities associated with H. pylori were found to show changes in the species-specific and quantitative composition of the colonic microbiocenosis, which were symptomatic and revealed by bacteriological studies in 47.5% of cases and severe in 32.5%. When antihelicobacter therapy is planned, a through treatment of all family members and, if possible, pets should be made. Colonic microbiocenosis should be monitored while treating Helicobacter infection.

Endoscopic and clinical findings in first-degree relative of duodenal ulcer patients and control subjects

The first-degree relatives of duodenal ulcer patients and of control probands were evaluated clinically and by gastroduodenal endoscopy for prevalence of duodenal ulcer. The control probands were randomly selected from a control population. 199 relatives of 51 duodenal ulcer probands were interviewed, and 154 of these were endoscoped. 154 control relatives who had been endoscoped were matched with the DU relatives according to sex and age. Endoscopic evidence of present or past duodenal or pyloric ulcer was present in 20 (13.0%) of the DU relatives and in only 6 (3.9%) of the control relatives (p less than 0.01). The frequency of macroscopic duodenitis and gastric erosions was also significantly higher (p less than 0.05) in DU relatives than in controls. A history of epigastric pain was obtained in 54 (35.1%) of endoscoped DU relatives and in 24 (15.6%) of control relatives (p less than 0.01). This study has shown an increased prevalence of endoscopic evidence of duodenal ulcer in the first-degree relatives of duodenal ulcer patients. The finding that duodenitis is also more prevalent in DU relatives than in controls support the view that duodenitis is linked with duodenal ulcer.
