Sixty nine patients with non-ulcer dyspepsia have been studied with endoscopy, biopsy, quick urease (CLO) test, Helicobacter pylori culture, and the 13C-urea breath test before and after treatment with tripotassium dicitratobismuthane (DeNol) two tablets twice daily for four weeks. Symptoms of non-ulcer dyspepsia were recorded using a standard questionnaire. Using H pylori culture as the gold standard, the sensitivity of the 13C-urea breath test was 90%, the specificity 98.6%, and the accuracy 94.8% with a positive predictive value of 98.2% and a negative predictive value of 92.5%. Conversion rate from H pylori positive to negative status after treatment with tripotassium dicitratobismuthate was 17.9%. Symptoms of non-ulcer dyspepsia improved appreciably after treatment irrespective of H pylori status. The 13C-urea breath test is an accurate research tool suitable for serial testing and population surveys. [ABSTRACT FROM PUBLISHER] |
