About this study

Official title: Effect of Curcumin Food Supplement on Gut Microbiota in Children With Irritable Bowel Syndrome

To evaluate the effect of curcumin food supplement on gut microbiota of children with irritable bowel syndrome (IBS) and to review any correlation between the changes in the microbiota with symptoms.

Read the detailed description

This is a prospective, placebo-controlled, double blinded, randomized control trial. This study will evaluate the effect of curcumin food supplement on gut microbiota of children with irritable bowel syndrome. Curcumin is a commonly used spice in Asian cooking and has a very good safety profile. Developing preparation of this compound for targeted delivery in the GI tract would provide a novel way to treat common FGID. This study will provide preliminary data for future studies to evaluate the role of gut microbiota in the pathophysiology of pain predominant FGID and how food supplements can be used to manipulate the microbiota.

Being tested
Curcumin, Placebo
Keywords
Curcumin, IBS and microbiota
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CurcuminDietary supplement

    The curcumin food supplement will be administered in the form of capsules. Participants in the treatment arm will take 50 mg twice or three times a day, depending on their body weight. Participants will take the curcumin capsules for eight weeks.

  • PlaceboDietary supplement

    The placebo will be administered in the form of capsules. Participants in the placebo arm will take a capsule twice or three times a day, depending on their body weight. Participants will take the placebo capsules for eight weeks. The placebo capsule will be similar in size, shape and color to the curcumin capsule and they will contain inert food powder.

Study groupRoleWhat they receive
TreatmentExperimentalPatients in the treatment arm with weight between 35 kg to 50 kg will receive 50 mg capsule of curcumin twice a day (maximum dose 2.8 mg/kg/day, which is within the GRAS approved dose) and those over 50 kg in weight will receive three curcumin capsules a day (maximum dose 3 mg/kg/day, within GRAS recommended dose). Study duration will be 8 weeks.

What is being measured

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

  1. Alteration in Gut Microbiota

    To study the alteration in gut microbiota with 8-week curcumin dietary supplementation in children with IBS between the ages of 10 yrs to 18 yrs

    Measured: 8 weeks

Secondary outcomes (1)
  1. Comparison of GI Symptoms

    To compare the GI symptoms at baseline and after 8-weeks of curcumin dietary supplementation we will be using a previously validated Irritable Bowel Syndrome Severity Scoring System (IBS-SSS) questionnaire (Francis CY, Morris J, Whorwell PJ. The irritable bowel severity scoring system: a simple method of monitoring irritable bowel syndrome and its progress. Aliment Pharmacol Ther 1997; 11(2): 395-402). This questionnaire measures symptom severity and includes a scale of "none" to "very severe" or "very happy to very unhappy" or "not at all" to "completely" as well as "often/occasionally/never." The maximum achievable score is 500 and mild, moderate and severe cases are indicated by scores of 75 to 175, 175 to 300 and >300 respectively. Higher scores means worse outcome and vice versa. At the end of the 8-weeks curcumin supplementation any absolute or relative decrease in the total score in comparison to baseline will considered as improvement in outcome.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Curcumin in people with Irritable Bowel Syndrome, run by Medical College of Wisconsin at 1 site 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 4 inclusion and 25 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 21 Feb 2021. 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 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. Some participants in this study may receive a placebo. 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?

Alteration in Gut Microbiota (time frame: 8 weeks). 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 21 Feb 2021.
