Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder in children and adults that causes injury to the esophagus. At the present time, the only way to make the diagnosis and follow the response to therapies is by repeated endoscopies of the upper GI tract to obtain tissue biopsies for examination under the microscope.
This creates a heavy burden on patients and families. The procedure is invasive and has inherent risks. It is also expensive, causes missed school days, and forced time off from work for the parents.
Currently, there is no highly sensitive and specific non-invasive blood test available to monitor the disease.
Gastroenterologists Barry Wershil of Lurie Children's and Children’s Research Center of Chicago and Amir Kagalwalla of Lurie Children's have joined forces with molecular biologist Steven Ackerman of the University of Illinois at Chicago to investigate a panel of non-invasive biomarkers in the blood and/or urine of subjects with EoE that may ultimately be used for the diagnosis and assessment of remission, and recurrence or exacerbation of disease. Blood, urine, biopsies and other samples will be obtained from study volunteers and a detailed assessment of the sensitivity and specificity of these biomarkers will be determined. This research is being funded through the HOPE grant from the American Partnership for Eosinophilic Disorders
Dr. Wershil states: “Children with EoE may have to go through three or four upper endoscopies a year in order to make the diagnosis and assess their response to different therapies. It is the hope of all of us who take care of these patients that a reliable, non-invasive approach can be developed.”
