The morphology of the inflammation of the gastric and duodenum mucosa with Helicobacter pylori contamination

The aim of the study was to study the morphological features of the inflammatory processes of the mucous membrane of various parts of the stomach and duodenum in patients with chronic gastritis and duodenitis. 24 patients (18 men and 6 women) were observed with chronic gastritis and duodenitis associated with Helicobacter pylori. The average age of the patients was 47 years. 120 biopsy samples of the mucosa of different parts of the stomach and duodenum were studied using histological, histochemical, morphometric and microbiological methods. Histological and microbiological examination of biopsy specimens revealed chronic antral gastritis, chronic fundal gastritis and chronic diffuse pangastritis. Superficial chronic duodenitis was rare and was erosive only in 11.4%. Helicobacter pylori in biopsy of stomach samples were detected more often in associations of various forms. Chronic antral gastritis of the type B was characterized by a predominantly high activity of the pathological process, moderate atrophy of the pyloric glands and a high incidence of small bowel metaplasia...
