Dietary Fiber Mixture in Constipated Pediatric Patients (MIXFIBER)

April 11, 2011 updated by: Federal University of São Paulo

A Controlled, Randomized, Double-blind Trial to Evaluate the Effect of a Dietary Fiber Mixture During Maintenance Treatment and on Colonic Transit Time in Constipated Pediatric Patients

The purpose this study was to to evaluate the therapeutic effect of a fibers mixture in the treatment of chronic constipation and on the colonic transit time in children.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In spite of an increase in the consumption of fibers being indicated for the treatment of constipation, few clinical trails have evaluated its efficiency. In the majority of prior studies only the effect of a single type of fiber was evaluated. Each type of fiber presents a particular characteristic, which determines its action mechanism and performance in different parts of the colon. Therefore, theoretically, greater effectiveness could well be observed when different types of fibers are associated into a single product for fiber supplementation.

A randomized, parallel, double-blind, controlled was performed to evaluate the effect of a dietary fiber mixture in constipated pediatric patients.

Children aged between 4 and 12 years were included in the study and the initial diagnosis of functional chronic constipation was made in accordance with the Rome III criteria. The children having attended the Pediatric Gastroenterology Ambulatory of the Federal University of Sao Paulo and the Santa Casa de Misericórdia hospital in Sao Paulo city. All of the children were undergoing constipation maintenance treatment with the use of a laxative in a dosage less than 1.0 ml/Kg for milk of magnesia, mineral oil or lactulose or less than 0.5 g/Kg for polyethylene glycol 3350.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
ACTIVE_COMPARATOR: Dietary Fiber Mixture
The dietary fiber mixture was composed of six different types of fibers. It was used for treatment of chronic constipation in children.
Dietary supplement: Dietary Fiber Mixture

During the four weeks the patients received fiber mixtures (intervention) or maltodextrine as the placebo. The fiber mixture was composed of six different types of fibers: 10.5% fructooligosaccharides, 12.5% inulin, 24% Arabic gum, 9% resistant starch, 33% Soya polysaccharide e 12% cellulose.

The dose was defined in accordance with the child's body weight: 6.3 grams of fiber supplement, which corresponds to 4.8 g of fiber, or placebo(1 table spoon) twice per day, diluted in 200 mL of a milky chocolate drink for children weighing up to 18 kg; 12.6 grams of fiber supplement, which corresponds to 9.6 g of fiber, or placebo (2 table spoons) twice per day, diluted in 200 mL of a milky chocolate drink for children weighing more than 18 Kg.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical response - Therapeutic success
Time Frame: 4 weeks
The primary outcome result measurement was the therapeutic success. This therapeutic success was considered when the patient demonstrated daily evacuations or had interposing days of pasty consistency, without pain or difficulty and the absence of fecal incontinence during the 4 weeks of intervention, without the need of using a laxative or rectal enema.
4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequent daily evacuations, format and consistency of the feces, total and segmental transit time
Time Frame: 4 weeks

The format and consistency of the feces was evaluated in accordance with the Bristol Stool Form Scale (stool are rated based on water content of the feces, with 1 meaning hard stools to 7 meaning liquid stools).

The colonic transit time was evaluated during the study's final week by way of the method proposed by Bouchoucha et al. (1992).
