Study summary

Medication use, especially NSAIDs and PPIs, prior to diagnosis is considered a risk factor for MC development. However, the exact pathophysiological mechanism is unclear. It is hypothesized that NSAIDs, PPIs, and SSRIs may have an effect on the colon permeability, due to an idiosyncratic reaction which results in a local immune response. MC patients are considered to be susceptible hosts, prone to react on administration of abovementioned drugs. In order to test this hypothesis and to generate new insights in the pathophysiology of MC, we want to perform an Ussing chamber experiment using fresh colon tissue samples. The primary objective is to assess ex vivo the effect of NSAIDs and PPIs on epithelial permeability of colon biopsy specimens of MC and non-MC patients, using the Ussing chamber system

Inclusion criteria

  • The indication for colonoscopy is a relapse of MC (active) / MC in remission (remission) / no MC (control)
  • Patient is not treated with NSAIDs / PPI / SSRI in week before inclusion

Exclusion criteria

Exclusion Criteria:

  • Age below 18 years at the time of diagnosis
  • Use of anticoagulants or drugs
  • Severe co-morbidities hindering an endoscopic procedure
  • A previous history of any type of chronic colitis, IBS, IBD, colon carcinoma or (partial) colectomy
  • A recent (last year) diagnosis of infectious diarrhea or radiation proctitis.
  • Use of medication known to influence intestinal permeability
  • Excessive alcohol usage (>20 standard units per week)
  • Not capable of signing an
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 19, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
