Vela, M.D., M.S. ResearchMayo Clinic is a leader in eosinophilic esophagitis research and actively researches eosinophilic disorders. Clinical trials are underway to study long-term management and remission of eosinophilic esophagitis. Mayo Clinic researchers are also studying the use of a device called the Cytosponge as a replacement for endoscopy to monitor ongoing treatment for eosinophilic esophagitis. The Cytosponge is a small sponge inside a capsule attached to a string. You swallow the capsule, which dissolves; the doctor then pulls out the sponge, scraping cells off your esophagus. It's quick, inexpensive, minimally invasive and does not require anesthesia. The Allergic Diseases Research Laboratory at Mayo Clinic's campus in Rochester, Minnesota, investigates the mechanisms of common airway and skin diseases. The lab focuses on and studies types of immune cells, especially eosinophils, a type of white blood cell. Laboratories in the areas of clinical immunology and immunotherapeutics, immunology, and gastroenterology and hepatology also are involved in research on eosinophilic disorders.
