Barrett's esophagus is an increasingly common disease that is strongly associated with reflux of stomach acid and usually a hiatus hernia, and it strongly predisposes to esophageal adenocarcinoma (EAC), a tumor with a very poor prognosis. We report the first genome-wide association study on Barrett's esophagus, comprising 1,852 UK cases and 5,172 UK(More)
The gastric IgA response to Helicobacter pylori was examined in 100 dyspeptic patients by means of immunoblotting of supernatants from antral biopsy and gastric mononuclear cell cultures. 76 of 78 patients with chronic gastritis, 2 of 8 with reactive gastritis, and 1 of 14 subjects with normal mucosa showed positive responses. Of patients with chronic(More)
The existence of a distinctive form of chronic gastritis characterized by marked infiltration of the surface and pitlining epithelium by mature T lymphocytes has been confirmed. Seventeen cases were identified amongst 382 patients with active chronic gastritis (4.5 per cent). The cases with lymphocytic gastritis had significantly higher counts of(More)
The symptomatology of a case of acute infection with Helicobacter pylori is described, together with the accompanying changes in gastric mucosal histology, local and systemic humoral immune response, and gastric ascorbic acid concentration. The patient was an endoscopist, previously negative for the carbon-14 urea breath test, who had a week of epigastric(More)
Ultrastructural examination of biopsies showing Helicobacter pylori associated chronic gastritis reveals close attachment between gastric surface epithelial cells and the organism. The finding of 'adhesion pedestals', which represents a cellular response to the presence of the organism, is analogous to the response of intestinal cells to enteropathogenic E(More)
The histological features of non-autoimmune chronic gastritis are consistent with those of a local immune response by the gastric mucosa. If Campylobacter pylori is causative in this condition, then the immune response will be in part specific for this organism. Antibodies to C. pylori are present in the gastric juice of infected patients. Coating of(More)
Biopsy specimens of gastric and duodenal mucosa from 290 patients were examined histologically for metaplasia and Campylobacter pyloridis. Estimates of pH on samples of fasting gastric juice from 55 of the patients were performed, and mucosal biopsy specimens from 33 patients were also cultured for C pyloridis. Active duodenitis was seen in 34 duodenal(More)
Duodenal biopsy specimens from 471 adults and 47 children were examined to determine the prevalence and distribution of gastric epithelium in the duodenal bulb in relation to age, gender, gastroduodenal inflammation, smoking, alcohol and consumption of nonsteroidal anti-inflammatory drugs (NSAID). Gastric metaplasia was present in the anterior wall duodenal(More)
AIMS To investigate whether Helicobacter pylori infection or autoimmune gastritis is responsible for the reported increase in gastric pathology and abnormalities of gastric function in patients with coeliac disease and dermatitis herpetiformis (DH). METHODS Serum H pylori IgG antibodies were assayed by enzyme linked immunosorbent assay and intrinsic(More)
