Clinical Trial Summary
Background: Gastric glitch is a new functional disease characterized by severe and transient
epigastric pain occurring after challenges such as drinking alcohol and eating specific
foods. Aims: In this N-of-1 trial, we first characterized the clinical and gastric
tomographic images of a patient with gastric glitch highly reproducible after alcohol
challenging, and then tested the effect of prucalopride and buspirone on the prevention of
gastric glitch crises.
Description:
Objective: To evaluate the effect of prucalopride and buspirone, compared to placebo, in the
prevention of gastric pain crises, in a double-blind clinical trial of a single patient.
Methods: Female, 35 years old, with signed consent to participate in the study, received 15
capsules to take 1 capsule 60 minutes before ingesting 200 ml of red wine at home (≈20 grams
of alcohol), twice a week, according to her routine food, totaling 15 meals. Thus, the
experimental phase lasted about eight weeks. The 15 capsules contain placebo (5 capsules),
prucalopride 2 mg (5 capsules) or buspirone 10 mg (5 capsules), prepared by a specialized
pharmacy in such a way that their physical characteristics do not allow the identification of
which agent is being administered, neither by the patient nor the investigator controlling
the trial (double-blind). The aforementioned pharmacy generated a code for each pill,
randomly, and provided a sealed list with the 15 codes and their respective drugs, for
disclosure after the end of the study. The patient was instructed to record in a standardized
diary the occurrence of pain crises after the wine challenge, as well as their duration and
intensity (Likert 0 to 10: maximum pain), and accompanying symptoms. The patient was asked to
contact the researchers directly (WhatsApp) throughout the trial, to clarify any doubts or
need for some assistance due to the occurrence of symptoms related to the study. The study
statistics will be descriptive in terms of pain events, and the effect of the drugs will be
evaluated in a statistical model suitable for the N-of-1 trial. Prucalopride is a 5-HT4
receptor agonist that accelerates gastric emptying, while buspirone is a 5-HT1A receptor
agonist that enhances gastric accommodation function. The presumed pathophysiology underlying
the patient's pain is retention of wine in the gastric lumen, causing pain. Stimulating
gastric emptying with prucalopride or increasing the accommodation of the gastric fundus with
buspirone could prevent or alleviate the pain crisis.
