About this study

Background:

Bacteria and other microorganisms that live in the intestines (the gut microbiome) play an important role in a person s health. The gut microbiome helps to regulate the immune system and control inflammation. Imbalances in the gut microbiome have been linked to illnesses such as inflammatory bowel disease (IBD). People diagnosed with IBD can have serious health problems. Researchers want to know more about how the gut microbiome affects the development and progression of IBD in children. In this natural history study, they will compare the gut microbiomes of healthy children with those who have IBD.

Objective:

To collect stool and samples of intestine tissue from children with and without IBD undergoing colonoscopy.

Eligibility:

People under 21 years old who are having a colonoscopy at the Inova Health System or Pediatric Specialists of Virginia.

Design:

Participants will fill out a questionnaire. They will answer questions about their history. Topics may include how they were fed as infants; how they were born; and how often they took antibiotics.

Stool and tissue samples from the intestines will be taken during the participants colonoscopy. They may also give samples of blood and urine.

Participants may be asked to provide additional stool, blood, and urine samples. They may do this up to 3 times per year. These samples may be collected at the clinic; they may also be collected at home and mailed to the researchers.

If they have more colonoscopies, participants may be asked for more tissue samples.

Participants will be enrolled for up to 10 years.

Read the detailed description

The gut microbiome (community of microorganisms in the intestines) serves many important roles in healthy people, including immune system regulation and anti-inflammatory functions. A dysbiosis (imbalance) in the gut microbiome is associated with many immune mediated diseases, including inflammatory bowel disease (IBD). The microbiome is thought to play a central role in the development and propagation in IBD. Studies have shown that in IBD, the gut microbiome demonstrates increased pro-inflammatory bacteria, a reduction in anti-inflammatory bacteria and overall reduced diversity. Inflammatory bowel disease is complicated and comes at a high burden to those affected. While affecting both children and adults, patients diagnosed before 18 years of age often have more severe phenotypes than those diagnosed in adulthood. Patients affected by IBD often have many complications such as linear growth failure, decreased bone mineral indices, delayed puberty, malnutrition and need for surgeries. At this time, we have limited ability to predict which patients will go on to develop complications and the time points in which these may occur.

Further, there are many comorbidities present in patients with IBD including dermatologic manifestations, hepatobiliary disease, other immune-mediated disease such as celiac disease as well as endocrinopathies. Children with IBD and these comorbid conditions are thought to have higher morbidity and decreased quality of life. While the gut microbiome is thought to mediate the development of many of these diseases, there is little literature associating clinical and microbiome drivers of those with IBD and these additional comorbidities.

Given that the microbiome may have a role in potentiating the inflammatory pathways contributing to IBD, there is potential to identify microbial signatures to help determine disease outcomes such as complications and response to treatment. In this study, we intend to examine differences in the microbiome diversity and composition in children with IBD and controls. We will then follow subjects longitudinally to determine initial microbiota signatures and changes for those who develop comorbidities, complications and therapy responsiveness.

We hope that by elucidating the microbiome of these children, we will have the opportunity to better understand the pathogeneses of co-morbid diseases, ultimately enabling the development of microbiome-based therapeutics for these conditions.

What is being measured

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

  1. differences in fecal/intestinal microbiome

    Determine differences in fecal/intestinal microbiome of patients IBD as compared to controls

    Measured: at diagnosis

  2. differences in fecal microbiome diversity and composition

    Determine differences in fecal microbiome diversity and composition in children with IBD with and without comorbidities

    Measured: longitudinal throughout follow up

  3. microbiome signatures for newly diagnosed IBD patients

    Determine if microbiome signatures for newly diagnosed IBD patients can predict complications and response to treatments

    Measured: longitudinal throughout follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Inflammatory Bowel Disease and Crohn's Disease, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in United States.

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 1 inclusion and 1 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: withdrawn, as of the sponsor's last update on 1 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 was withdrawn before enrolling participants, so there are no results.

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?

differences in fecal/intestinal microbiome (time frame: at diagnosis). The study lists 3 primary outcomes in all. 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 1 Jun 2023.
