Background summary
Many patients with gastro-oesophageal reflux disease (GORD) report an
association between stress and symptoms of GORD. Results of studies using
experimentally induced stress show an increase in symptoms but no increase in
objective reflux parameters. This points towards a role of hypersensitivity to
gastro-oesophageal reflux during stressful circumstances. We hypothesize that
the sensitivity of the distal oesophagus to acid might be modulated by acute
stress.
Study objective
to investigate the relationship between acute psychological stress and
perception of acid in the distal oesophagus in healthy volunteers and GORD
patients.
Study design
The study consists of two parts. First the study is conducted with healthy
volunteers. After all measurements are completed, the same measurements are
performed with GORD patients. All participants will undergo stationary
oesophageal manometry, pH monitoring and an acid perfusion test twice, one
measurement without and one with the presence of an acute psychological
stressor. The order of these two measurements will be randomised. Before each
measurement participants will have to fill in a questionnaire in order to
compare subjects* anxiety scores on the two different days. We will use a
modified Raven Progressive Matrices IQ Test to induce acute psychological
stress.
Study burden and risks
Participants will undergo routine stationary oesophageal manometry, pH
monitoring and acid perfusion test twice. There will be one week between both
measurements. Oesophageal manometry and pH monitoring are routine
investigations at our department.
