Number of participants that the trial has enrolled
46
Results
The gGlu-HMRG assay substantially elucidated H. pylori GGT activity in vitro.
The ex vivo H. pylori GGT-activatable fluorescence assay is potentially applicable for rapid diagnosis of H. pylori infections.

Baseline Characteristics
men 31, women 15.
mean age, 63.8 and 70.1 years, respectively.
Participant flow
All 46 participants underwent esophagogastroduodenoscopy at Nagasaki University Hospital. One biopsy was taken from the antrum and one from the body of the stomach.
Adverse events
none
Outcome measures
We investigated whether gGlu-HMRG was activated by GGT produced by H. pylori cells and emit fluorescence in vitro. An ex vivo imaging assay for GGT activity with gGlu-HMRG was conducted to detect H. pylori infection using clinical samples(biopsy from the antrum and the stomach body ) .
