The Colonic Transit Time: a Modifiable Determinant of Intestinal Production and Uptake of Microbial Metabolites?

NCT ID: NCT01869751

Last Updated: 2020-04-24

Basic Information

• Recruitment Status: WITHDRAWN
• Study Classification: OBSERVATIONAL
• Study Start Date: 2013-05-31

Brief Summary

Chronic kidney disease is associated with the accumulation of various metabolites, i.e., uremic retention solutes. Evidence is mounting that the colonic microbiome contributes substantially to these uremic retention solutes. Indoxyl sulfate and p-cresyl sulfate are among the most extensively studied gut microbial metabolites, and are associated with cardiovascular disease, chronic kidney disease progression and overall mortality. Colonic transit time is an important determinant of intestinal generation and uptake of bacterial metabolites. However, it is unknown if accelerating the colonic transit time reduces the intestinal generation and uptake of indoxyl sulfate and p-cresyl sulfate. Prucalopride is a selective, high-affinity 5-HT4 receptor agonist with a stimulating effect on colonic motility and transit. It is currently used in treating chronic slow-transit constipation. An observational study will be initiated in non-chronic kidney disease patients with chronic slow-transit constipation necessitating treatment with prucalopride to observe its effect on serum concentrations and intestinal generation of indoxyl sulfate and p-cresyl sulfate.

Eligibility Criteria

Inclusion Criteria

• Age ≥ 18 and ≤ 85 years
• Chronic slow-transit constipation as defined be 4 criteria:

1. having two or fewer spontaneous complete bowel movements week for a minimum of 6 months

2. having one or more of the following symptoms for at least one-quarter of the time: lumpy/hard stools, a sensation of incomplete evacuation, or straining during defecation.

3. slow transit time as determined by Rx colon transit study ("pellet")

4. without evidence of secondary constipation or primary defecation disorder

• Need of therapy with prucalopride (i.e., inefficacy of dietary changes and laxatives)
• Follow-up visit possible after 4 weeks of treatment
• Written informed consent

Exclusion Criteria

• History or new diagnosis of organic intestinal disease (e.g., inflammatory bowel disease, malignancy)
• Secondary constipation (drug-induced, endocrine, metabolic or neurological disorders, surgery, known or suspected organic disorders of the large intestine, or megacolon) or primary defecation disorder
• Use of laxatives two days before start of treatment and during treatment period. If there is no spontaneous bowel movement during 3 consecutive days, rescue treatment with bisacodyl and/or enema is allowed if necessary
• Presence of significant co-morbidity (uncontrolled heart, liver and lung disease)
• Pregnancy
• Chronic kidney disease, i.e., estimated glomerular filtration rate (MDRD) < 60 ml/min/m² or need of dialysis therapy

• Maximum Eligible Age: 85 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
