Abstract
Helicobacter (Campylobacter) pylori has been cultured from the antral biopsies of 85-90% of patients of gastritis, gastric ulcer and duodenal ulcer at different centres. Studies conducted all over the world have firmly implicated this organism in the aetiology of active superficial gastritis and recurrences of duodenal ulcer. Two hundred patients with upper abdominal pain, distension, vomiting and/or haemetemesis were subjected to OGD scopy. In 163 of these patients there was endoscopic evidence of gastritis; in 24 there was DU; in 3, GU and in 10 it was normal. Diagnosis of H pylori infection was made by the rapid biopsy urease test which is nearly 100% specific and 98% sensitive. 170 out of 200 patients were positive for H pylori. Among these were 138 patients of gastritis (84.6%); 22 cases of DU (91.6%); 2 cases of GU (66.6%) and 8 in whom endoscopy was normal. Histological examination of the antral biopsy specimens showed mild to severe infiltration of mucosa with lymphocytes and plasma cells. None of the 170 H pylori positive cases showed polymorphonuclear infiltration which has been stressed repeatedly by most Western authors to be characteristic of "active" superficial gastritis associated with H pylori infection. Even in those with a history of dyspepsia of barely 4 weeks duration or less there was no PMN infiltration in the mucosa. Thus the local response to infection by H pylori of the gastric mucosa is different in Indian patients.
