Two studies published in The New England Journal of Medicine show mixed results in treating EoE. Dupilumab is found to be effective in children under 12, while benralizumab fails to provide significant relief for patients. These findings challenge the long-held assumption that eosinophils are the primary cause of the disease.
The American College of Allergy, Asthma & Immunology (ACAAI) has issued a position paper on the safety of administering live vaccines to patients treated with dupilumab. The review suggests that treatment should not be stopped, but rather, shared decision-making between doctors and patients is recommended to weigh risks and benefits.

A new review reveals that environments beyond greenspaces and bluespaces, such as caves, deserts, and glaciers, have potential health benefits. Short-term exposure to solid-state water landscapes showed little evidence of benefits, while longer-term exposure led to improved emotional states, medical treatments for allergies, and physic...
A new study found that eliminating animal milk alone from the diet of adults with eosinophilic esophagitis is just as effective as eliminating six common foods, including animal milk, eggs, wheat, soy, fish, and nuts. The one-food elimination diet may be a more manageable option for people with EoE.
