Official title

The Use of Fractionated Exhaled Nitric Oxide in the Diagnosis and Assessment of Disease Activity of Eosinophilic Esophagitis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to evaluate the relationship between fractionated exhaled nitric oxide, peripheral eosinophils, and plasma citrulline and ß-alanine in patients with eosinophilic esophagitis (EoE) compared to those without EoE. The hypothesis is that a combination of elevated fractional exhaled nitric oxide, increased peripheral eosinophils, and elevated plasma citrulline and ß-alanine is associated with active EoE.
