Methods for diagnosing and treating eosinophilic esophagitis
Disclosed are methods of diagnosing and treating a subject with active or inactive eosinophilic esophagitis (EoE). The methods may include the steps of detecting whether a level of eosinophil lineage-committed progenitor (EoP) is elevated in a blood sample obtained from a subject, diagnosing the subject with active EoE when an EoP level in the sample is elevated above a pre-determined cut-off value and diagnosing the subject with inactive EoE when the EoP level in the sample is below a pre-determined cut-off value; and treating the subject diagnosed with active EoE. Kits related to same are also disclosed.
1. A method of diagnosing and treating a subject with active or inactive eosinophilic esophagitis (EoE) in a patient suffering from EoE, comprising the steps of
a. detecting whether a level of eosinophil lineage-committed progenitor (EoP) is elevated in a blood sample obtained from said subject;
b. diagnosing said subject with active EoE when said EoP level in the sample is elevated above a pre-determined cut-off value and diagnosing said subject with inactive EoE when said EoP level in the sample is below a pre-determined cut-off value; and
c. treating said subject diagnosed with active EoE;
wherein when said EoP level is below a cut-off of about 15.5 EoPs per mL (esophageal eosinophils/HPF) of blood, said subject is diagnosed with inactive EoE, and wherein when said EoP level is above a cut-off of about 15.5 EoPs per mL of blood, said subject is diagnosed with active EoE.
2. The method of claim 1 , wherein said treatment step comprises administration of steroids, administration of a proton-pump inhibitor, withdrawal of one or more food types, an amino-acid based formula diet, or a combination thereof.
