• W143117466 abstract "The relationship between Campylobacter pylori (CP), histologic gastritis, and dyspeptic symptoms is becoming gradually clearer, but there is still a lack of knowledge of the natural history of treated or untreated gastritis. We examined serial biopsies from the gastric fundus, body, and antrum, and from the duodenum in 16 dyspeptic patients. Patients with concomitant peptic ulcers, alcoholism, or nonsteroidal anti-inflammatory drug use were excluded. CP was present in the biopsies of 50% of patients at presentation. When CP was present, the antrum was always infected, and often had the highest density of organisms. In the duodenum, CP was found only in areas of gastric metaplasia. The presence of CP was highly correlated with gastritis activity (neutrophilic infiltrate). A 4-yr follow-up study of symptoms, endoscopic appearance, and histologic findings including the presence of CP was performed in 10 of the original 16 patients. After 4 yr, both the severity and frequency of epigastric pain remained the same in seven patients, worsened in one, and improved in two. All patients who had CP at initial presentation retained the organism (5/10), whereas none of the previously noninfected patients acquired the infection (5/10). Both CP-positive and -negative patients were treated for 3 wk with 524 mg bismuth subsalicylate qid, and for the first 2 of 3 wk with 250 mg metronidazole qid. One patient who was CP positive was lost to follow-up. In three of the remaining four patients on this regimen, the organism was eradicated. Of the nine patients who completed the treatment program, two had no change in symptoms and seven improved. CP was present in three of seven with improved symptoms and in one of two with no change in symptoms. After treatment, the only change in histology was the disappearance of activity in the CP-positive patients who lost the organism. In conclusion, CP was present in 50% of dyspeptic patients with endoscopic evidence of at least one erosion. Both the symptoms and CP persisted for 4 yr. Dyspeptic symptoms improved after bismuth subsalicylate/metronidazole therapy, regardless of the presence or absence of CP, although the regimen did succeed in eradicating the organism in three of the four CP-positive patients who completed the study." @default.
