Further study details as provided by Jason Gaglia, Joslin Diabetes Center:

Primary Outcome Measures:
  • Change in Markers of Autoimmunity [ Time Frame: Baseline and day 3 post challenge ]
    Blood samples for markers of autoimmunity will be taken before and day 3 post challenge.

Secondary Outcome Measures:
  • Gastrointestinal Symptoms [ Time Frame: Baseline and 6 days ]
    Gastrointestinal symptoms are recorded in a standardized diary at baseline and for 6 days inclusive of challenge.

Enrollment: 7
Actual Study Start Date: August 2013
Study Completion Date: December 2014
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Celiac Disease Alone Gluten Challenge Dietary Supplement: Gluten Challenge
Three-day gluten containing dietary challenge.
Sham Comparator: Celiac Disease Alone Sham Challenge Dietary Supplement: Sham Challenge
Three-day sham (gluten free) dietary challenge
Experimental: Celiac Disease and T1D Gluten Challenge Dietary Supplement: Gluten Challenge
Three-day gluten containing dietary challenge.
Sham Comparator: Celiac Disease and T1D Sham Challenge Dietary Supplement: Sham Challenge
Three-day sham (gluten free) dietary challenge

Detailed Description:
Participants meeting eligibility criteria will have blood collected before and after a three-day oral gluten challenge. This blood will be tested for biomarkers associated with islet autoimmunity and gluten-specific cellular immunity.

Ages Eligible for Study:   18 Years to 50 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of Celiac Disease by histology and serology

Exclusion Criteria:

  • Not following a gluten free diet for at least 12 months
  • Known gluten exposure within the prior 2 months
  • Treatment with systemic immune modifying biological agents (adalimumab, etanercept, infliximab, certolizumab pegol) in prior 6 months
  • Treatment with systemic immunomodulatory agents in prior 30 days
  • Human immunodeficiency virus infection, untreated hepatitis B virus, or hepatitis C virus infection
  • Nut allergy
  • Hemoglobin level below normal range
  • History of angina
  • Pregnant or lactating
  • Severe symptoms to gluten challenge in the past
  • Elevation in transglutaminase-IgA or deamidated gliadin peptide IgA or IgG greater than or equal to 50% above upper limit of normal
  • Uncontrolled complications of type-1 diabetes or celiac disease which pose a risk to participation
