Summary of current CEGIR projects

Dr. Pesek’s current research project is to characterize the demographics, medical history, and clinical presentations of patients with eosinophilic gastritis (EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC) as well as analyze the pathology information obtained during endoscopy that was used to make these diagnoses.

Q & A with Dr. Pesek

How has CEGIR participation made a difference in your career, or how do you anticipate it will?

“The CEGIR training program has made me a better clinician for my patients. It has allowed me to have a better understanding of the ongoing research in the field but also allows me to connect with clinicians across the country. Through involvement with patient advocacy, I have gained a better understanding of the challenges that patients and families face when they are diagnosed with an EGID.”

How do you feel the patient community benefits from the CEGIR training program?

“CEGIR has allowed patients and families direct access to clinicians and researchers. They also have direct input into study development as well as access to results, something that is not seen in many areas.”
