| gastritis. bringing this enigma into sharper focus. | type a and type b (probably campylobacter pylori) gastritis are distinct clinical (but largely asymptomatic) and histologic entities that can be separated from other disease processes. while the association of c pylori gastritis with peptic ulcer disease is well documented, no causal relationship has been established. acute inflammatory conditions of the stomach secondary to other disease processes, macroscopic abnormalities of the gastric mucosa, and sometimes poorly characterized epigastric pa ... | 1988 | 3344261 |
| histological gastritis in duodenal ulcer: relationship to campylobacter pylori and effect of ulcer therapy. | antral gastritis has been described in up to 100% of patients with duodenal ulcer disease, and recently has been associated with campylobacter pylori infection. the present study examines the effect of two ulcer therapies (cimetidine and colloidal bismuth subcitrate) on this lesion. sixty-four consecutive patients with endoscopically diagnosed duodenal ulcer were randomized to treatment with either agent upon entry into the study. antral biopsies were taken at both initial and final endoscopies ... | 1988 | 3344730 |
| campylobacter pylori is associated with chronic gastritis but not with active peptic ulcer disease. | campylobacter pylori is supposed to be involved in the pathogenesis of gastroduodenal peptic ulcer diseases and chronic gastritis. in order to study whether the campylobacter pylori in the stomach of peptic ulcer patients is related to ulcer itself or to a co-existing chronic gastritis, we examined the frequency of the bacteria in giemsa stained histological sections of biopsy specimens from a series of patients with active peptic ulcer and from series of non-ulcer control subjects. we found no ... | 1988 | 3345253 |
| acid secretion and serum gastrin levels in individuals with campylobacter pylori. | campylobacter pylori may cause gastritis and has been proposed as an etiologic factor in the development of peptic ulcer. however, it may be an acid-sensitive microbe and before it can be implicated in the pathogenesis of peptic ulcer, it should be consistently found in ulcer patients with normal acid secretion. thirty-six patients with c. pylori by warthin-starry stain underwent gastric analysis; 25 were normochlorhydric and 11 hypochlorhydric. ulcers were present in 19 normochlorhydric patient ... | 1988 | 3345893 |
| effect of age on the frequency of active campylobacter pylori infection diagnosed by the [13c]urea breath test in normal subjects and patients with peptic ulcer disease. | we studied the frequency of active campylobacter pylori infection in persons from north america (n = 53) or the people's republic of china (n = 15) who had no gastrointestinal symptoms or a history of ulcer disease and in patients with active or recently active duodenal or gastric ulcers diagnosed by endoscopy (n = 105). c. pylori infection was significantly (p less than .001) more frequent in patients with peptic ulcers (88%) than in the normal group (45%). an age-related increase in the freque ... | 1988 | 3346569 |

| bacteria of the gastric antrum and their relation to chronic gastritis. | biopsy samples from the gastric antrum were taken from 61 patients. on bacteriological culture, campylobacter pylori was isolated in 27 subjects. thirty-four patients had chronic gastritis, as seen in routine-stained histological sections. by means of the may-grünwald-giemsa (mgg) staining technique, bacteria were demonstrated in sections from 26 subjects. of these, 22 had gastritis histologically. in 13 subjects, structures similar to campylobacter pylori were found in mgg-stained sections, 11 ... | 1988 | 3348915 |
| [campylobacter pylori--status of knowledge from the morphologic viewpoint]. | the morphological alterations of the gastric mucosa due to campylobacter pylori (c.p.) were examined with high resolution light microscopy, scanning electron microscopy, and transmission electron microscopy. on the ultrastructural level the number and distribution of bacteria were correlated to the extent of the inflammatory resp. degenerative epithelial alterations. intestinal metaplasia was always free of bacteria, even with strong colonization of the residual mucosa. in comparison to the gast ... | 1988 | 3352454 |
| campylobacter pylori infection in patients undergoing endoscopy in fiji. | forty two patients (20 fijian and 22 indian) presenting for endoscopy at the colonial war memorial hospital, suva, fiji, were biopsied to detect campylobacter pylori infection. detection of the organism's urease activity in biopsy material or seeing the organism in warthin-starry silver stained histology sections were used to diagnose infection. thirty-nine patients (93%) were infected; 19 of 20 fijians (95%) and 20 of 22 indians (91%). of the 39 infected patients, 37 (95%) had chronic active ga ... | 1988 | 3353031 |

| effect of treatment on campylobacter pylori in peptic disease: a randomised prospective trial. | this study investigated the effect of colloidal bismuth subcitrate and cimetidine on campylobacter pylori in peptic disease. in 74% of 135 patients with peptic disease diagnosed at endoscopy c pylori was detected before treatment. compared with cimetidine, colloidal bismuth subcitrate significantly decreased the incidence of c pylori after six weeks of treatment (p less than 0.001). in the colloidal bismuth subcitrate group, subsequent healing of the lesion was correlated with the clearance of c ... | 1988 | 3356357 |
| campylobacter pylori-associated gastritis. is antibiotic therapy now justified? | campylobacter pylori clearly is a common inhabitant of the human stomach and is associated with nonautoimmune antral gastritis, chronic peptic ulceration, and non-ulcer dyspepsia. this editorial reviews whether therapy is now justified for patients with this infection. the criteria that must be fulfilled before an association can be considered to be of etiologic significance are discussed in relation to c. pylori infection and clinical disease. an overview of therapeutic approaches to eradicate ... | 1988 | 3356873 |
| antibody response to campylobacter pylori in an ethnic group lacking peptic ulceration. | the association between duodenal ulcer, gastritis and gastroduodenal colonization with campylobacter pylori suggests a causal role for this newly described bacterium. in an attempt to challenge the verity of this association we studied a group of people in whom duodenal ulcer is apparently absent. serological evidence of infection was sought with a sensitive, specific elisa assay for c. pylori specific igg and was compared with results from control sera from teenagers referred for respiratory vi ... | 1988 | 3363304 |

| gastritis and campylobacter pylori in healthy, asymptomatic volunteers. | a high prevalence of histologic gastritis in asymptomatic individuals has been reported in the literature. the studies have been poorly controlled for gastritis risk factors. we evaluated 20 healthy, asymptomatic volunteers free of known risk factors for gastritis with endoscopy, mucosal biopsy, culture, and gastric ph determination. the prevalence of gastritis on histologic examination was found to be 20%. there was no relationship between the presence of macroscopic findings at endoscopy and t ... | 1988 | 3365082 |
