Efficacy of colloidal bismuth subcitrate vs. cimetidine for treatment of helicobacter pylori positive non-ulcer dyspepsia.

ABSTRACT

We report an open trial study to determine the role of Helicobacter pylori (HP) in patients with non-ulcer dyspepsia (NUD) and to determine the effect of two drugs (colloidal bismuth subcitrate, CBS and cimetidine) on HP. Our study consisted of 48 patients, 30 received CBS two tablets twice daily and 18 received cimetidine 400 mg twice daily. The result of HP suppression detected by rapid urease test was 66.7% and 86.7% for CBS group after receiving the drug for 4 and 8 weeks respectively, for cimetidine only 11.1% urease test negative during the same period. Follow up urease test 19.2% of patients treated by CBS remained negative but none in the cimetidine group. AII patients felt better during treatment irrespective to status of HP. Our conclusion is that there is no correlation between HP status and NUD symptoms. To evaluate this relationship, further study must be done. To date there is no strong evidence to recommend HP eradication in HP associated NUP patients.
