About this study

Official title: Exploratory, Randomized, Double-blind, Placebo-Controlled Study on the Effects of Bifidobacterium Infantis in Active Celiac Disease

This exploratory study has been designed to determine the effect of the probiotic Bifidobacterium infantis vs. placebo orally administered over a period of 3 weeks on clinical features, Quality of Life parameters (QoL), intestinal permeability and inflammatory markers of patients having positive serological evidences of Celiac Disease.

Read the detailed description

Objective: This exploratory study has been designed to determine the effect of the probiotic Bifidobacterium infantis vs. placebo orally administered over a period of 3 weeks on clinical features, Quality of Life parameters (QoL), intestinal permeability and inflammatory markers of patients having serological evidences of CD (positive serological markers). The testing period will be approximately three weeks between the results of serological testing and before the intestinal biopsy procedure during which time subjects are consuming a gluten-containing diet.

Study Design: A 3-weeks duration, placebo-controlled, double-blind, randomized study plan in ambulatory (non-hospitalized outpatients) patients, with 2 parallel groups. Treatment arms will be as follows:

A). Placebo 2 capsules 3 times daily (morning, evening and night).

B). Probiotics (Bifidobacterium infantis) 2 capsules 3 times per day (morning, evening and night).

What is being measured

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

  1. Intestinal permeability changes

    Subjects will come to the laboratory after an overnight fast, ingest the sugar probes, and collect all urine passed over the ensuing 24 hours into a pre-weighed container with 5 ml of 10% thymol in isopropanol. Urine will be vigorously mixed, total volume recorded, and aliquots rapidly frozen for subsequent transport and analysis. To evaluate intestinal permeability, subjects will ingest a solution containing: 5 g lactulose (Technilab, Montreal, Quebec, Canada), and 2 g mannitol (Sigma, St Louis, Missouri, USA) in 450 ml of water (osmolality approximately 1800 mOsmol/l).

    Measured: 21 days

Secondary outcomes (1)
  1. Changes in the cytokine profile.

    Mononuclear cells obtained from blood will be isolated by Ficoll-Hypaque density centrifugation and resuspended in complete media/Dulbecco's modified Eagle medium. These mononuclear cells will be termed peripheral blood mononuclear cells (PBMCs). PBMCs will be incubated, nonstimulated, for 72 hours at 37°C in a 5% CO2 humidified atmosphere. Nonstimulated PBMC cytokine reflects the cytokine milieu from wich the PBMCs were originally isolated. Interleukin(IL)-10 and IL-12p40 cytokine levels will be measured using enzyme-linked immunosorbent assays.

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

A study testing Probiotic in people with Celiac Disease, run by Bai, Julio M.D. at 1 site in Argentina.

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 8 inclusion and 16 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 13 Feb 2012. 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 Argentina. 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?

Intestinal permeability changes (time frame: 21 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01257620, which also lists 16 linked publications.

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 13 Feb 2012.
