Pilot Study of Diet and Behavior in Children With Autism

This study has been completed.

First received: June 19, 2012
Last updated: NA
Last verified: June 2012
History: No changes posted
We hypothesize that in children with autism dietary antigens can change the intestine, making it "leaky" and then affecting the brain changing their behavior.

Condition Intervention
Dietary Supplement: Gluten and dry milk
Dietary Supplement: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Supportive Care
Official Title: PILOT STUDY: The Physiological Basis for Dietary Protein Intolerance in Children With Autism

Further study details as provided by The University of Texas Health Science Center, Houston:

Primary Outcome Measures:
  • Intestinal Permeability [ Time Frame: baseline, 2 weeks and 4 weeks ]
    Changes in intestinal permeability and behavior with changes in diet

Secondary Outcome Measures:
  • Psychometric testing [ Time Frame: baseline, 2 weeks and 4 weeks ]
    Behavioral variables: hyperactivity, innatention, irritability

  • Gastrointestinal symptoms [ Time Frame: baseline, week 2, week 4 ]
    Changes in gastrointestinal symptoms with different diets

Enrollment: 12
Study Start Date: October 2008
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Gluten and Milk group
Subject on a gluten and dairy free diet will receive supplement of gluten and dry milk daily
Dietary Supplement: Gluten and dry milk
0.5 g/kg/day of gluten 0.5 g/kg/day of dry milk
Other Name: Gluten and dairy group
Placebo Comparator: Rice flour
Subjects will be on a gluten and dairy free diet and receive daily supplement of rice flour (placebo)
Dietary Supplement: Placebo
Rice flour 1.0 g/kg/day
Other Name: Control group

Detailed Description:
Subjects in 2 different diets (gluten/dairy and placebo) will be monitored for changes in intestinal permeability (urine lactulose mannitol ratio) and behavior (psychometric testing).
