Eosinophilic esophagitis: does age matter?

Introduction: Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus with increasing prevalence worldwide. It is a multifactorial disease caused by a combination of immunologic, genetic, and environmental factors. The clinical presentation of EoE varies largely, especially between different age groups. While diagnostic criteria and therapeutic goals are similar in children and adults, there are differences in treatment, with a more cautious approach in children to avoid growth disturbances. In addition, close monitoring and follow-up are essential in children to ensure uninterrupted growth. Areas covered: A search in PubMed/MEDLINE, EMBASE, and SCOPUS databases was conducted to identify relevant studies published between January 2010 and January 2023 to give an overview of the state-of-the-art of EoE epidemiology, diagnosis, and treatment while focusing on similarities and differences between the adult and the pediatric population. Expert opinion: The current state of research indicates that while significant progress has been made in understanding and treating EoE, further research and advances are needed to optimize diagnostic strategies, tailored treatment approaches, monitoring, and follow-up, and improve long-term outcomes for patients. With further innovation, the management of EoE can become more precise and tailored, leading to better patient outcomes and improved quality of life.
