Do patients with eosinophilic esophagitis have baseline increased esophageal mucosal impedance?
And will treatment that reverses esophageal eosinophilia in patients, correct abnormalities in mucosal impedance?

Experimental: Mucosal Impedance
Patients with Eosinophilic Esophagitis and patient without trouble swallowing,during your clinical endoscopy (a standard procedure that allows your doctor to look at the inside of your swallowing tube), the 2.13 mm catheter (tiny tube), called an Intraluminal Impedance, will be passed through the channel of the standard endoscope. This device has not been approved by the Food and Drug Administration (FDA) but it is considered to be minimal risk related to using it.
Device: Mucosal Impedance
Mucosal impedance- a (tiny tube) will be placed through the endoscope in your esophagus (swallowing tube) 5 cm above where your stomach and esophagus meet for 5 seconds.
This will determine if people with eosinophilic esophagitis (EoE) have an increased esophageal mucosa impedance (food getting into the esophageal tissue).
- Effective treatment is defined by the elimination of esophageal eosinophilia on follow up endoscopic biopsy. [ Time Frame: basesline to one year ]As a pilot, ten patients will be studied before and after treatment for eosinophilic esophagitis. This number of patients will be increased if there are treatment failures until there is a total of ten effectively treated patients studied. Effective treatment is defined by the elimination of esophageal eosinophilia on follow up endoscopic biopsy. Ten control patients without esophageal disease will be studied.
