Whole Gut Motility Patterns in Patients with Chronic Nausea and Vomiting

Area of Science:

• Gastroenterology
• Motility Disorders
• Pharmacology

Background:

• Chronic nausea and vomiting (N/V) are prevalent clinical issues.
• Gastrointestinal (GI) motility and gastric contraction patterns in N/V syndrome are not fully understood.
• Investigating the impact of prokinetic agents on N/V symptoms and motility is crucial.

Purpose of the Study:

• Compare GI transit times and gastric contractions in chronic N/V patients versus healthy volunteers (HVs).
• Evaluate the effects of Prucalopride on symptoms and motility in N/V patients.
• Determine if chronic N/V syndrome involves panenteric dysmotility.

Main Methods:

• Utilized the Motilis 3D-Transit system for baseline and post-treatment GI motility assessment.
• Administered Prucalopride (2 mg daily for 28 days) to N/V patients.
• Assessed patient symptoms using the Gastrointestinal Symptom Rating Scale (GSRS) and Gastroparesis Cardinal Symptom Index (GCSI).

Main Results:

• No significant differences in regional GI transit times between N/V patients and HVs at baseline.
• N/V patients demonstrated significantly lower gastric contraction amplitude compared to HVs (p < 0.001).
• Prucalopride treatment reduced gastric emptying time (3.1h to 1.6h, p < 0.005) and significantly improved GCSI scores.

Conclusions:

• Patients with chronic N/V syndrome exhibit impaired gastric contractility but not generalized dysmotility.
• Prokinetic agents like Prucalopride show potential for symptomatic relief in chronic N/V.
• Further research into N/V pathophysiology and targeted therapies is warranted.
