The purpose of this study is to determine whether the immune response causing celiac disease is related to the autoimmune response causing type-1 diabetes.

Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Change in Markers of Autoimmunity [ Time Frame: Baseline and day 3 post challenge ] [ Designated as safety issue: No ]
    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 ] [ Designated as safety issue: Yes ]
    Gastrointestinal symptoms are recorded in a standardized diary at baseline and for 6 days inclusive of challenge.

Estimated Enrollment: 52
Study Start Date: August 2013
Estimated Primary Completion Date: September 2015 (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.
