Detailed Description
The gold-standard for monitoring of dietary adherence is consultation with an expert dietitian, but this may be time-consuming for patients and local expertise may not be available. Intestinal biopsy is the only direct method to document mucosal healing and can be considered in all adults with celiac disease. Non-invasive assessment of compliance with a gluten free diet(GFD) can be achieved with monitoring of IgA antibodies to tissue transglutaminase (IgA-tTG) or deamidated gliadin peptides, as these markers improve with gluten elimination. However, intestinal mucosal damage is present in a significant number of patients who report compliance with a gluten free diet and have normalized serology, potentially due to dietary lapses or unrecognized contamination with gluten. Furthermore, serologic testing may be normal in patients with partial adherence. Patient reported surveys show promise for assessing gluten free diet adherence, but further studies are needed.
Intestinal fatty acid-binding protein (I-FABP), a small (15 kD) cytosolic protein found exclusively in the small bowel enterocytes, has been studied as a marker of intestinal epithelial damage in septic shock and mesenteric ischemia. More recently, elevated levels of intestinal fatty acid-binding protein( I-FABP) have been described as a marker of intestinal injury in both adults and children with celiac disease. Intestinal fatty acid binding protein, (I-FABP) levels have been shown to significantly correlate with the degree of villous atrophy and IgA antibody to tissue transglutaminase (IgA-tTG), as well as decrease upon treatment with a gluten free diet(GFD). Incomplete normalization of intestinal fatty acid binding protein(I-FABP) on a gluten free diet points to ongoing intestinal injury, even in the absence of circulating antibodies, thus suggesting its potential as a non-invasive marker for gluten free diet adherence and intestinal damage in celiac disease.
The measurement of gluten immunogenic peptides (GIP) in stool is a novel method to monitor gluten free diet compliance. Recently, a technique to detect gliadin 33-mer equivalent peptide epitopes (33EPs) in the stool of pediatric patients has been described. These peptides show significant resistance to digestion and were detected in healthy individuals after normal gluten-containing diet ingestion. Importantly, these peptides are not detected in patients on a gluten free diet, and there appears to be a correlation between the amount of gluten intake and the peptide levels. A similar test has been developed for gluten intestinal peptide(GIP) detection in urine, although there are currently no peer-reviewed studies examining this technique. Further research on the utility of stool and urine gluten intestinal peptide (GIP)for monitoring of gluten free diet (GFD) adherence is warranted.
Given the lack of a non-invasive and accurate measure of gluten intake in celiac disease (CD), the investigators will investigate the effect of gluten intake in celiac disease (CD) patients using a variety of markers. Patients who are symptom-free on a gluten free diet (GFD) will be exposed to various amounts of gluten. Factors that will be studied include the effect on patient estimated gluten intake, Celiac disease symptoms, IgA-tTG level,intestinal fatty acid binding protein( I-FABP) level, and both stool and urine gluten peptide levels.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Placebo controlled group
This is a group of same number of subjects as in other arms, who will be given equivalent dose of placebo- cornstarch capsules i.e 5 capsules containing neutral substance- cornstarch(placebo) to be taken daily by mouth for a period of 12 weeks.
|
After administering the capsules for 16 weeks during study periods, patients's blood will be tested for novel markers- Intestinal fatty acid binding protein(I-FABP), stool for gluten intestinal peptide (GIP), urine for gluten intestinal peptide(GIP), patient estimated gluten intake(PEGI), celiac severity index(CSI), Celiac dietary adherence test(CDAT) by standard questionnaire provided during the visits.
These tests will be done over a period of 16 weeks and at a follow up 3 months later.
|
Experimental: High dose gluten capsules
This group of subjects will be given high dose i.e 2.5 g of gluten containing capsules, 5 capsules to be taken daily by mouth, for a period of 12 weeks.
|
After administering the capsules for 16 weeks during study periods, patients's blood will be tested for novel markers- Intestinal fatty acid binding protein(I-FABP), stool for gluten intestinal peptide (GIP), urine for gluten intestinal peptide(GIP), patient estimated gluten intake(PEGI), celiac severity index(CSI), Celiac dietary adherence test(CDAT) by standard questionnaire provided during the visits.
These tests will be done over a period of 16 weeks and at a follow up 3 months later.
|
Experimental: Low dose gluten capsules
This group of subjects will be given low dose i.e 0.5 g of gluten containing capsules, 5 capsules to be taken daily by mouth, for a period of 12 weeks.
|
After administering the capsules for 16 weeks during study periods, patients's blood will be tested for novel markers- Intestinal fatty acid binding protein(I-FABP), stool for gluten intestinal peptide (GIP), urine for gluten intestinal peptide(GIP), patient estimated gluten intake(PEGI), celiac severity index(CSI), Celiac dietary adherence test(CDAT) by standard questionnaire provided during the visits.
