Study Details
Study Description
Brief Summary

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).

Outcome Measures
Primary Outcome Measures
- Intestinal permeability changes [21 days]
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).
Secondary Outcome Measures
- Changes in the cytokine profile. [21 days]
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.
