Abstract:
Eosinophilic esophagitis results in a chronic immune-mediated condition of the esophagus characterized by esophageal dysfunction and eosinophil-predominant inflammation. While food-based oral immunity therapy (OIT) is a recognized trigger for eosinophilic esophagitis, the impact of sublingual immunotherapy (SLIT) for aeroallergens is less well established. We present an unusual case of eosinophilic esophagitis in a 14-year-old male induced by SLIT and resolved after discontinuing SLIT with Timothy grass pollen allergy extract (GRASTEK®, ALK-Abelló, Inc., Bedminster, USA), which, to our knowledge, has not been previously reported.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
