Outcome Measures
Primary Outcomes (1)
Number of patients with increase in Oral Nitric Oxide levels
To determine if oral NO correlates to activity of disease in EoE
one year
Interventions
o Oral nitric oxide is measured by a breathing test where the participant will be seated in a chair and asked to breathe out into a small hand-held instrument for about 6 seconds.
