Endoscopic classification of chronic gastritis based on a pilot study by the research society for gastritis

DIGESTIVE ENDOSCOPY, Issue 4 2002
Michio Kaminishi
Background:,Various types of classification of gastritis have been proposed, but no plausible classification has been available until now. The Research Society for Gastritis performed a pilot study to establish an endoscopic classification, taking into consideration the following: (i) ease of use; (ii) permitting everyone the common image; and (iii) presence of histopathological evidence. Methods:,One hundred and fifty-five patients were enrolled and underwent gastroscopy. Eight basic endoscopic and histological types of gastritis (superficial, hemorrhagic, erosive, verrucous, atrophic, metaplastic, hyperplastic and special types) were defined. Gastritis was endoscopically diagnosed according to the definition of the endoscopic types of gastritis. Four or more biopsy specimens were obtained from the lesser and the greater curvatures of the antrum and the corpus of each patient, and the histological findings of gastritis and Helicobacter pylori infection were assessed. The histological diagnosis of gastritis was made according to the definition of histology types of gastritis. The endoscopic and the histological diagnoses were then compared in a blinded fashion. Results:,Endoscopic diagnosis was 62% as sensitive as histological diagnosis for erosive gastritis, 67% for verrucous gastritis and 84% for atrophic gastritis in the antrum. In superficial gastritis, sensitivity was approximately 25% in the corpus, but only 8% in the antrum. Metaplastic and hyperplastic gastritis were correctly diagnosed only in severe cases. Conclusion:,Five basic types of gastritis (superficial, erosive, verrucous, atrophic and special types) should be employed for the new endoscopic gastritis classification. Metaplastic and hyperplastic gastritis are considered to be subtypes of atrophic gastritis and they should be excluded from the basic endoscopic classification. A new definition of gastritis in the antrum accompanied by redness still remains to be investigated. [source]

Expression of COX-1, COX-2 and inducible nitric oxide synthase in superficial gastritis, mucosal dysplasia and gastric carcinoma

JOURNAL OF DIGESTIVE DISEASES, Issue 3 2001

OBJECTIVE: To investigate the significance of the expression of cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) in superficial gastritis, gastric mucosal dysplasia and gastric carcinoma, and to study the relationship between COX-2, iNOS, gastric carcinoma and Helicobacter pylori infection. METHODS: Polyclonal antibodies to COX-1, COX-2 and iNOS were used detect their expression and the status of H. pylori infection in 92 specimens of paraffin-embedded gastric tissue. Of the 92 patients, 33 had superficial gastritis, 30 had gastric mucosal dysplasia and 29 had gastric cancer. Helicobacter pylori was detected by toluidine blue staining. RESULTS: Expression of COX-2 and iNOS in gastric cancer (65.5%, 62.1%) was significantly higher than that in gastritis (18.2%, 18.2%; P < 0.01). Expression of COX-2 and iNOS in gastritis with H. pylori infection was higher than that in gastric mucosal dysplasia with H. pylori infection. The expression of COX-2 and iNOS occurred concomitantly in gastritis, dysplasia and gastric cancer. CONCLUSION: Inflammation and H. pylori infection may be able to stimulate the expression of COX-2 and iNOS, which might be involved in gastric carcinogenesis. [source]

HISTOPATHOLOGICAL PATTERN OF GASTRIC BIOPSIES OF HELICOBACTER PYLORI POSITIVE PATIENTS IN SARDJITO GENERAL HOSPITAL, YOGYAKARTA, INDONESIA

Objective: To determine the gastric histopathological types distribution of H. pylori positive patients who were detected histopathologically. Material& Methods: Study design was prospective study. Consecutive patients who were suffering chronic dyspepsia underwent endoscopy examination between August 1998 and December 1999. The biopsy specimens were taken from gastric antrum and corpus and sent to the pathologist for histopathology type and H. pylori examinations. H. pylori were also confirmed with CLO and IgG-Helicobacter pylori tests. Results: There were 92 patients (48 male (M) and 44 Female (F) who underwent gastric biopsies endoscopically between August 1998 and December 1999. Fifty-six (60.87%) patients were chronic superficial gastritis, 11(11.96%) chronic antropic gastritis, 18 (19.56%) chronic gastritis 2 (2.17%) chronic gastritis with metaplasia, 3 (3.27%) gastric ulcer, and 2 (2.17%) gastric signet-ring cell carcinoma. Twenty one (22.8%) patients with H. pylori positive by histopathology examination with CLO and IgG-H.pylori tests. Those were 5 (8.90%) patients with chronic superficial gastritis, 7(63.63%) chronic atrophic gastritis, 3(100%) gastric ulcer, 2 (100%) chronic gastritis with metaplasia, 3(16.67%) chronic gastritis, 1(50%) signet-ring cell carcinoma. The age range of the H. pylori positive patients were between 16 and 76 years old. Conclusion: Twenty one (22.8%) H. pylori positive patients out of 92 endoscopied patients and the high percentage tendency of H. pylori positively in chronic atrophic gastritis, gastric ulcer, and chronic gastritis with metaplasia, although most of the patients had chronic superficial gastritis. Further study is needed with larger with larger sample to get the clearer picture of H. pylori distribution based on gastric histopathological types. [source]

A decade-long sour-taste sensation successfully treated with a proton-pump inhibitor

JOURNAL OF ORAL REHABILITATION, Issue 10 2005
N. MANTANI
summary We report a case study of a 54-year-old Japanese woman who persistently suffered from a sour-taste sensation in her mouth for 10 years, and was treated with a proton-pump inhibitor (PPI). She found sour-tasting meals irritable, and after eating such meals the sour-taste sensation worsened. She also complained of eructation and regurgitation. Upper gastrointestinal (GI) endoscopy showed duodenal erosion, superficial gastritis, and erosive oesophagitis. After 2 weeks of PPI therapy (lansoprazole, 30 mg day,1) the sour taste subjectively decreased to 70%, and after 6 weeks the symptoms disappeared. In addition to increased sensitivity of the mouth, gastro-oesophageal reflux might have created her obstinate sour-taste sensations. It is suggested that in such cases PPI therapy should be attempted. [source]
