Brief Summary

Our purpose is to look at esophageal, stomach, and small intestinal permeability in a groups of Eosinophil Gastrointestinal Disorders and Dysautonomic Patients

Aim

1) To determine the permeability of the esophagus, stomach, and small bowel in patients with eosinophilic disease (with and without dysautonomia) as compared to normals and patients with dysautonomia alone

2) To determine whether permeability decreases after therapy and to stratify improvement based upon therapeutic modality

3) To determine whether alteration of diet in patients will alter small bowel permeability regardless of whether they have overt small bowel involvement in disease.

4) To correlate clinical symptoms with permeability in each cohort

Inclusion Criteria

Participants will consist of 3 different groups

1. Eosinophilic gastroenteritis and esophagitis patients with a known history of >15 eos/HPF in the esophagus (n=35)

 - subset with dysautonomia symptoms and lab findings (n=10) - the rest (n=25) with eosinophilic esophagitis without dysautonomia symptoms

 - subsequently, eosinophilic patients who have controlled disease via dietary modification(n=20)

2. Dysautonomia patients without known eosinophilia patients (n=15)

3. Normal controls - without known GI disease or symptoms (n=15)

Exclusion Criteria

 

Comorbidities that preclude osmotic test for permeability (i.e. diabetes, severe heart disease, reanl failure on daily diuretics or pulmonary hypertension)

Known compliance issues

Known contraindication to sucrose/lactose/mannitol administration
