Gastrointestinal dysfunction in children with autism spectrum disorders

Area of Science:

• Pediatric Neurology
• Gastroenterology
• Developmental Psychology

Background:

• Gastrointestinal (GI) dysfunctions are frequently reported in children with autism spectrum disorder (ASD).
• These GI issues are increasingly recognized as a significant comorbid condition in ASD.
• The clinical significance and characteristics of GI dysfunction in ASD require further delineation.

Purpose of the Study:

• To describe the clinical characteristics of GI dysfunction in a cohort of children with ASD.
• To identify associated comorbid disorders and evaluate GI conditions through endoscopic and colonoscopic examinations.
• To explore the relationship between GI symptoms and other clinical features in ASD.

Main Methods:

• A cohort of 164 children with ASD evaluated at a pediatric neurology practice was studied.
• Data collected included parental reports of chronic GI complaints, diarrhea, constipation, bloating, gas, vomiting, and gastroesophageal reflux.
• Endoscopic and colonoscopic evaluations were performed on a subset of subjects (n=12).

Main Results:

• Gastrointestinal dysfunction was prevalent, with 49% reporting chronic GI complaints.
• Specific symptoms included diarrhea (22%), constipation (26%), bloating/gas (13%), and vomiting/reflux (10%).
• Gut inflammation was found in 6 of 12 evaluated subjects, independent of clinical symptoms; GI dysfunction was linked to sleep disorders and food intolerance.

Conclusions:

• Gastrointestinal dysfunction is highly prevalent in children with ASD, aligning with parental and clinical observations.
• GI dysfunction in ASD warrants thorough evaluation and appropriate treatment strategies.
• The association with sleep disorders and food intolerance suggests potential pathways for intervention.
