How Dr. Markowitz’s research is transforming health care

Dr. Markowitz is an expert and thought leader in the clinical management of eosinophilic esophagitis (EoE). He has been involved with two of the largest published trials of elemental diet for this disorder. His practice serves as a referral center for pediatric patients across the southeastern United States with EoE. His practice is a site for epidemiologic studies on EoE as well as several industry sponsored drug trials. Dr. Markowitz and his collaborators are currently developing protocols for maximizing response to dietary therapy as well as medical therapy for EoE. They are currently designing a study to evaluate for previously unrecognized environmental mediators of EoE.

Dr. Markowitz is a cofounder of the Carolinas Eosinophilic Esophagitis Collaborative, which brings together clinical and research experts from across North and South Carolina to further the science regarding diagnosis and treatment of EoE. The collaborative is just completing its first epidemiologic allergy practice in Charlotte, and the Medical University of South Carolina. Members of the collaborative have been meeting twice yearly for 2 years.
