Researchers identify hypermobility-linked autonomic subtype of eosinophilic esophagitis in children

Roughly one in four children with eosinophilic esophagitis (EoE) also has joint hypermobility, and this group is disproportionately likely to report chronic light-headedness on standing, according to a study from Ann & Robert H. Lurie Children's Hospital of Chicago published in the Journal of Allergy and Clinical Immunology.¹

The combination of gastrointestinal, musculoskeletal, and autonomic symptoms was associated with meaningfully worse quality of life than EoE alone.¹

“With recognition of this disease subtype, clinicians need to routinely screen children with EoE for hypermobility and chronic light-headedness because we have simple treatments for these symptoms that can make a huge difference in these children’s quality of life,” said senior author Joshua B. Wechsler, MD, MSCI, medical director of the Eosinophilic Gastrointestinal Diseases Program at Lurie Children’s and assistant professor of pediatrics and medicine at Northwestern University Feinberg School of Medicine.

Study design and findings in pediatric EoE

The prospective study enrolled 80 patients with EoE, aged 2 to 21 years, who underwent esophagogastroduodenoscopy at Lurie Children’s between January 2021 and March 2024.¹

Patients or caregivers completed validated instruments, including the Pediatric Eosinophilic Esophagitis Symptom Survey, a quality-of-life measure, and the Composite Autonomic Symptom Score (COMPASS-31).¹

Both active histologic disease and joint hypermobility were independently associated with greater autonomic symptom burden, and orthostatic light-headedness was more frequently reported by girls with EoE.¹

Investigators also examined gastric and duodenal mast cell counts, which have been proposed as a potential link between hypermobility, dysautonomia, and GI symptoms in other conditions, though their specific relevance to this EoE subgroup remains unclear.¹

Disease burden and unmet need in EoE

EoE is a chronic, antigen-driven type 2 inflammatory disease of the esophagus that can cause dysphagia, odynophagia, food impaction, and, in young children, faltering growth.²

Recent reviews note that phenotypic and symptom variation across EoE populations is increasingly recognized, even as core histologic and endoscopic severity measures remain the primary tools for diagnosis and monitoring.²

Non-GI symptoms such as light-headedness are easy to overlook in a standard gastroenterology visit, particularly because patients may not volunteer brief or intermittent episodes unless specifically asked.

Joint hypermobility and dysautonomia in EoE

Joint hypermobility and autonomic dysfunction frequently co-occur and have separately been linked to gastrointestinal symptoms and reduced quality of life in other patient populations.¹

A connective tissue link to EoE has also been reported previously: children with inherited connective tissue disorders show a markedly higher prevalence of EoE than the general pediatric population.³

Taken together with the new findings, this suggests overlapping mechanisms between connective tissue laxity, autonomic regulation, and esophageal eosinophilic inflammation that are not yet fully characterized.

Expert interpretation

Wechsler noted that light-headedness often surfaces indirectly in clinic. “Patients often don’t mention light-headedness on their own, since they might not pay much attention to brief episodes. But they might mention headache that commonly appears afterwards,” he said, adding that clinicians should ask directly about light-headedness when chronic headache is reported.

Proposed management is conservative: increased fluid and salt intake and exercise for orthostatic symptoms, and structured physical therapy to strengthen periarticular musculature and reduce injury risk in hypermobile joints.

Limitations and next steps

The study is observational, single-center, and based on patient-reported symptom instruments rather than autonomic function testing such as tilt-table studies, limiting causal conclusions about mechanism. The sample size (n=80) also limits subgroup analyses.

Wechsler said it remains unknown whether the EoE–hypermobility–dysautonomia association is specific to EoE or reflects a broader pattern across inflammatory or allergic conditions, a question the group intends to pursue in future work. The study was funded by Dysautonomia International.
