The effect of Helicobacter pylori eradication on symptoms and gastric emptying in patients with nonulcer dyspepsia.
OBJECTIVE
This study was undertaken to evaluate the effect of eradication therapy on the symptoms of Helicobacter pylori positive non-ulcer dyspepsia patients.


METHODS
Twenty-four patients participated in the study and the symptoms of daytime epigastric pain, night or hunger pain, nausea, vomiting, regurgitation, bloating, belching, early satiety and anorexia were scored at the beginning, the 15th day after starting eradication therapy (amoxicillin 2 gr bid, clarithromycin 2 gr bid and omeprazole 40 mg daily for two weeks) and during the third and sixth months. Gastric emptying of radiolabelled solid meal was determined at baseline and during the third month.


RESULTS
The Helicobacter pylori eradication rate was 79% and symptom scores significantly decreased during the follow-up period in both of the groups, irrespective of Helicobacter pylori status. The mean symptom scores of the 24 patients at baseline, day 15 and and months three and six were as follows: 1.275, 0.274, 0.496 and 0.238 respectively. Symptom scores for the 19 patients with Helicobacter pylori eradication were 1.084, 0.263, 0.347 and 0.215 respectively while in the five patients in whom Helicobacter pylori eradication therapy failed it was 2.0, 0.314, 1.06 and 0.32 respectively. Of the 16.6% Helicobacter pylori positive non-ulcer dyspepsia patients who had delayed gastric emptying of solids, there was no change after eradication therapy. Nine patients, including all of those in whom eradication therapy failed, required further medication (antacids/prokinetics) for continuing symptoms one month after completion of treatment.


CONCLUSIONS
The results of this study suggest that Helicobacter pylori is a causal factor in symptoms of non-ulcer dyspepsia and that eradication therapy improves symptoms and endoscopic findings but has no effect on gastric emptying.
