BACKGROUND: Non ulcer dyspepsia (NUD) is being postulated as one of the gastroduodenal manifestations of H. pylori infection. H. pylori infection may result in clinical symptoms as well as histological changes in NUD. AIM: To compare clinical symptom score and histological changes in H. pylori (Hp) positive and negative untreated NUD patients. METHODS: Forty six patients with dyspeptic symptoms and normal upper GI endoscopic examinations were included in this study. During endoscopy 2 biopsies each were taken from the antrum and body of the stomach. These biopsies were used for rapid urease test (RUT) and histological examination. Patients were diagnosed to have Hp infection if either of two tests were positive. There were two groups of patients: Hp positive and Hp negative NUD patients. Clinical scoring using Glasgow dyspepsia score (Max. 20) and histological analysis, using Sydney system (Max score 11) was done and compared for both the groups of patients. Clinical scoring, RUT and histological scoring were blinded to each other. RESULTS: H. pylori was present in 29(63%) of the 46 patients. Mean clinical score for H. pylori positive patient was 10.9 while for Hp negative patient was 11.4. Total histological score for Hp positive and Hp negative patients was 3.37 Vs 1.76 (antrum) and 3.68 Vs 1.29(body) (p < .001), respectively. The only histological change found to be statistically significant between Hp positive and Hp negative patients was presence of lymphoid follicles (p < .05). CONCLUSION: Clinical scoring does not correlate with the presence of H pylori or histological severity. In NUD patients positive for H. pylori, there is a significant increase in the severity of gastritis both in the antrum and the body.
