A study of Helicobacter pylori in north Indian subjects with non-ulcer dyspepsia. Indian Journal of Gastroenterology. 1992 Apr; 11(2): 76-9http://imsear.searo.who.int/handle/123456789/63523A prospective case control study was conducted in 50 patients with non-ulcer dyspepsia (NUD) and 10 age and sex matched controls to determine the prevalence of Helicobacter pylori in patients with NUD and to correlate symptoms, histology and presence of H pylori in gastric biopsies. Endoscopic biopsies from antrum and fundus were subjected to urease test and histological examination. On histology, H pylori was identified in 27 (54%) NUD patients and in one of 10 controls. Urease test was positive in 31 (62%) antral and 21 (42%) fundal biopsies in patients with NUD and in only one (10%) of 10 antral biopsies in the control group. On histology, gastritis was present in the antrum in 46 (92%) NUD patients and in the fundus in 40 (80%) cases; of these, 27 (54%) and 15 (30%) had H pylori in antral and fundal biopsies respectively. The severity of antral gastritis correlated with the density of H pylori (p < 0.05).engAdolescentAdultDyspepsia --microbiologyFemaleGastritis --microbiologyGastroscopyHelicobacter Infections --complicationsHelicobacter pyloriHumansIndiaMaleMiddle AgedProspective StudiesJournal Article
