About this study

Official title: Evaluation of the Expression of Natural Killer T Cells (NKT) Marker in the Gut of Patients With Primary Sclerosing Cholangitis (PSC) Complicated by an Inflammatory Bowel Disease (IBD)

Inflammatory bowel diseases (IBD) include Crohn's disease (CD) and ulcerative colitis (UC). These diseases are a public health problem because they concern many patients (1 case in 1000). IBDs are characterized by dysregulated immune response against luminal antigens causing chronic inflammation of the gut in genetically predisposed individuals. Their exact cause is unknown and there is currently no cure. The primary sclerosing cholangitis (PSC) is a liver inflammatory disease of unknown origin that is known to be strongly associated with IBD. An important clinical observation highlights the mild symptoms of IBD when associated to the PSC. Conversely, treating PSC by liver transplant or immunosuppressive drugs is associated with a progression of intestinal inflammation.

Based, on these clinical findings that suggest a protective effect regulator of liver inflammation on intestinal inflammation, and on the results obtained by our group in mouse models that identified the natural killer T cell (NKT) as essential in control of experimental colitis, the project aims to determine, using PCR, if the expression of NKT cell markers are increased in the colon of patients with PSC+IBD compared to patients with IBD alone or PSC alone.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The increase in the expression of the NKT marker Valpha24 mRNA by PCR in the colon of patients with PSC alone, PSC + IBD compared to patients with IBD alone

    Measured: Through study completion, an average of 1 year

Secondary outcomes (2)
  1. The number of NKT infiltrating colonic biopsies, using immunohistochemical staining

    Measured: Through study completion, an average of 1 year

  2. The percentage of NKT cells among the peripheral blood lymphocytes by flow cytometry

    Measured: At the time of the inclusion

Questions about this trial

What is this clinical trial studying?

A study testing collection of gut biopsies collection of blood samples in people with Inflammatory Bowel Diseases and Primary Sclerosing Cholangitis, run by University Hospital, Lille at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The increase in the expression of the NKT marker Valpha24 mRNA by PCR in the colon of patients with PSC alone, PSC + IBD compared to patients with IBD alone (time frame: Through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Aug 2020; AzTrials last refreshed its copy on 8 Nov 2026.
