Colonic Motility in Patients With Diabetes

Overview

Background:

Gastrointestinal (GI) symptoms are overrepresented in patients with diabetes mellitus (DM) and often have a major impact on quality of life. Typical symptoms of diabetic enteropathy include abdominal pain, nausea, vomiting, diarrhoea, constipation, faecal incontinence, and bloating. Bowel symptoms in DM are usually caused by widespread dysfunction of the GI tract, but the exact pathophysiology remains incompletely understood. Within recent years, new methods for detailed assessment of GI motility have been developed. Hence, the electromagnetic 3D-Transit system is a safe, non-invasive method for detailed description of GI motility. The system tracks the exact position of an ingested electromagnetic capsule through the entire GI tract and provides detailed information on both regional transit- and contraction patterns. High Resolution Colonic Manometry (HRCM) allows extremely detailed description of contraction patterns in the colon. The HRCM is however an invasive method, as the catheter is placed during colonoscopy. HRCM has not previously been performed on diabetic patients and 3D-Transit has only been used sparingly.

Study Objectives:

The purpose of this study is to obtain detailed description of colonic contractions in patients with DM and gastrointestinal symptoms, especially during fast and after meals.

Hypothesis:

1. Patients with DM and GI symptoms have reduced high-amplitude, antegrade contractions in the colon when compared to healthy controls (HRCM).

2. Patients with DM and GI symptoms have reduced long, fast mass-movements when compared to healthy controls (3D-Transit).

3. The contractile response to a meal is reduced in patients with symptoms of diabetic enteropathy when compared to healthy controls.

Materials and methods:

20 patients with DM type 1 or 2 and GI symptoms will be investigated simultaneously HCRM and the 3D-Transit capsule. Data will be compared to the healthy from another study (CIV-19-05-028726). A colonoscopy is performed to install the HRCM catheter and place two 3D-Transit capsules within the colon. For 24 hours, the participants lie in a bed in the research lab while pressure changes from the HRCM catheter are recorded and the 3D-Transit capsules are followed through the gastrointestinal system.

Perspectives:

The study will add to the very limited data available on colonic dysfunction in DM.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: October 15, 2022

Interventions

  • Device: High Resolution Colonic Manometry and 3D-Transit system.
    • Not performed as an intervention, the study is observational.

Clinical Trial Outcome Measures

Primary Measures

  • High amplitude, antegrade contractions assessed with HRCM
    • Time Frame: All 24 hours of HRCM and 3D-Transit recording
    • Quantity, amplitude and duration of the high amplitude, antegrade propagating contractions accessed with HRCM, when compared to healthy controls.

Secondary Measures

  • Long, fast mass-movements assessed with 3D-Transit
    • Time Frame: All 24 hours of HRCM and 3D-Transit recording.
    • Quantity and length of the long, fast mass-movements assessed with 3D-Transit, when compared to healthy controls.
  • Distance of capsule movement.
    • Time Frame: All 24 hours of HRCM and 3D-Transit recording.
    • How do the length of a pressure change measured by HRCM correlate with the distance covered in long fast antegrade movements determined with the 3D-Transit system (cm).
