Ideology of Helicobacter pylori prevalence in peptic ulcer disease in an inner-city minority population.
OBJECTIVE
The prevalence of Helicobacter pylori infection among patients with peptic ulcer disease has been reported to range from 61 to 94%. Recent studies show a reduction in the prevalence of H. pylori infection in patients with peptic ulcer disease. This study was conducted to determine the prevalence of H. pylori infection in peptic ulcer disease in an inner-city hospital in Washington, DC.


METHODS
Medical records of all patients who had undergone upper gastrointestinal endoscopy from July 1997 through June 1999 were reviewed. All patients who had gastric ulcer and/or duodenal ulcer on upper gastrointestinal endoscopy were studied. Demographic characteristics, history of nonsteroidal antiinflammatory drug ingestion, alcohol consumption, and associated diseases were studied. H. pylori was considered to be present if CLOtest and/or histopathology were positive for H. pylori. Patients with negative pathology for H. pylori or negative pathology and CLOtest were considered negative for H. pylori.


RESULTS
One-hundred fifty-six patients were found to have gastric and/or duodenal ulcers. Fifty-one ulcer patients did not meet the inclusion criteria and were excluded. Among the 105 patients who were included in the study, gastric ulcers were found in 48 patients (45.7%), duodenal ulcers were found in 46 patients (43.8%), and both gastric and duodenal ulcers were found in 11 patients (10.5%). H. pylori was present in 66.7% of gastric ulcer patients and in 69.5% of duodenal ulcer patients. Antral histology and CLOtest were in agreement 96% of the time.


CONCLUSIONS
At the District of Columbia General Hospital, an inner-city hospital serving predominantly an African-American community, the prevalence of H. pylori in ulcer patients compares similarly to other more recent studies that have found a decreased prevalence of this bacterial infection in ulcer patients. This suggests that the treatment of H. pylori in minority patients is reducing the proportion of ulcers due to this bacterium, as has been seen with the majority population.
