Primary Outcome Measures:
  • Safety and efficacy of the gluten free casein free diet [ Time Frame: Measured at Weeks 6,18 and 30 ] [ Designated as safety issue: Yes ]
    Behavioral data: activity, sleep, behaviors related to the autism; Medical data: stool pattern, nutrition


Enrollment: 21
Study Start Date: January 2004
Study Completion Date: February 2009
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Participants will follow a gluten-free and casein-free diet for 18 weeks. The compliance with the diet was monitored with 24 hour dietary recall and nutritional sufficiency with diet diary analysis.
Behavioral: Gluten- and casein-free diet
Participants will follow a gluten-free and casein-free diet for 18 weeks. All children received individual EIBI interventions to decrease the confound of different types of therapies.
Active Comparator: 2
After established on a gluten free and casein free diet for at least 6 weeks, participants received double blind, placebo controlled challenges containing gluten, casein, gluten+casein, or placebo in a random order. Data was collected on behavioral and physiologic responses relative to the challenges. Children remained on the gluten free and casein free diet throughout this period.
Behavioral: Placebo controlled diet
Participants will follow a gluten-free and casein-free diet for 18 weeks. They will receive double blind placebo controlled challenge snacks that contain gluten, casein, gluten+casein or placebo with measurement of response. They remain on the gluten free and casein free diet for the entire study period.

Detailed Description:

Autism is a serious brain disorder that affects brain development and often causes social and educational problems. Prior studies suggested that a gluten- and casein-free diet may have a therapeutic effect on the behavior of children with autism. This study will examine the effects of such a diet on the behavior of children with autism who meet research diagnostic criteria, are monitored in adherence to the diet, and receive similar intense behavioral therapy.

Children in this study will be following a gluten free and casein free diet for 18 weeks. All subjects will have 6 weeks of baseline followed by 12 weeks of randomized, double-blind, placebo-controlled, challenge snacks with careful behavioral observation and evaluation. They also will be receiving uniform educational and behavioral services through their provider. Standard autism evaluation methods, weekly diet and sleep diaries and scheduled laboratory tests will be used to assess subjects. An end of study, follow-up assessment will be completed at 30 weeks after the start of the study.
