Abstract

Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder affecting 1 in 36 children in the United States. Given the rising prevalence and significant economic and social costs associated with ASD, it is critical that continued efforts be made towards better understanding the underlying etiology as well as management of the condition and its commonly associated comorbidities. It has been estimated that upwards of 70% of children with ASD have a positive history of gastrointestinal (GI) symptoms. In this retrospective, descriptive study, we identified 131 patients with diagnosis of autism spectrum disorder who presented for initial evaluation by pediatric gastroenterology at the Baystate Children's Specialty Center. We collected data from chart review of these patients with a particular focus on reason for referral, components of evaluation as well as results of said evaluation. Of the 131 patients, the most frequent reason for referral included constipation (42.7%), abdominal pain (27.5%), and feeding difficulties (26.7%). After completion of the evaluation, 60.3% of patients were ultimately diagnosed with a functional gastrointestinal condition. Of patients who completed endoscopic evaluation, 40% of patients were found to have grossly abnormal and 40% were found to have pathologically abnormal EGD. The majority of patients were recommended to have diagnostic evaluation; however, a large proportion of them were unable to complete said evaluation. The majority of patients were found to have abnormal testing; however, the majority of patients were additionally diagnosed with a functional gastrointestinal condition.
