Clinical Trial Summary

Aspirin can prevent ischemic vascular disease but is commonly complicated by dyspepsia in 30% of patients. Patients, who have aspirin related dyspepsia, commonly underwent upper endoscopy to exclude peptic ulcer disease or gastric cancers. For those without significant lesions in the stomach and duodenum (non-ulcer dyspepsia), the best approach in the management is unclear. The objective of this study is to compare the efficacy of esomeprazole and famotidine in the control of dyspeptic symptom. After giving consent, patients will be randomised to receive either esomeprazole 20 mg daily or famotidine 40 mg daily in a double blinded manner. The patient will be followed-up at the 2nd and 4th week. The study will be completed at the 4th week. The primary analysis will be the efficacy in the control of dyspepsia symptom between the two groups.

Description:

The objective of this double blinded randomized controlled study is to compare the efficacy of esomeprazole with famotidine in the control of dyspepsia in patients with aspirin related nonulcer dyspepsia NUD.

Method

The study shall be applied for approval from the Ethic Committee of Hong Kong West and East Cluster and shall be registered to the Clinical Trial Governance before the recruitment of the first patient.

Measuring instruments & Definitions

Hong Kong Dyspepsia Index (HKDI)

The presence or absence of dyspepsia was measured by the validated Hong Kong index of dyspepsia . This questionnaire could be used in epidemiological studies assessing the frequency and severity of dyspepsia in patient populations and also in interventional studies in functional dyspepsia.This index consisted of 12 questions on the severity of gastrointestinal symptoms, graded according to a five-point Likert scale (1- 5, from asymptomatic to very severe symptoms). A cut-off score of equal to or greater than 16 was determined to discriminate between controls and dyspeptic patients.

Global Dyspepsia Score

The global severity of dyspepsia will be measured by the Global Dyspepsia Score, which was a four-point scale in which a score of 0 indicated no pain or discomfort, a score of 1 mild pain or discomfort, a score of 2 moderate (annoying but not interfering with the daily routine) pain or discomfort, and a score of 3 severe (markedly interfering with the daily routine) pain or discomfort over the last 7 days . This scale is reliable, valid, and responsive and provides global assessment of symptoms in the western population . Significant dyspepsia was defined when Global Dyspepsia Score was more than or equal to 2 moderate.

Definition of significant endoscopic finding

Significant finding was defined as the presence of reflux esophagitis, Barrett's esophagus, gastric or duodenal ulceration, duodenal or esophageal erosions, or cancer and those with more than five gastric erosions on upper endoscopy. (Tally N, NEJM 1999)
