Original Question

Anaphylaxis is a life-threatening, acute hypersensitivity reaction and a typical medical emergency. Characterized by a rapidly evolving, systemic allergic response affecting multiple organs, it can quickly lead to respiratory collapse and, without prompt treatment, is often fatal. Anaphylaxis is usually an IgE-mediated (Type I) hypersensitivity reaction triggered upon re-exposure to a specific antigen. This reaction causes basophils and mast cells to degranulate, releasing various chemical mediators. The crosslinking of IgE antibodies on high-affinity receptors prompts this rapid mediator release (Palgan, 2023). The patient’s symptoms of angioedema, wheezing, and hypotension stem from uncontrolled bradykinin release. Bradykinin, a potent vasoactive peptide, increases vascular permeability, leading to angioedema, which typically presents as non-pitting swelling of the face, lips, or airway. Simultaneously, bradykinin-induced vasodilation and fluid extravasation cause hypotension and reflex tachycardia. The wheezing and hypoxia result from upper airway edema rather than bronchospasm, which explains why these symptoms do not respond to standard asthma treatments, such as bronchodilators or steroids. This pathophysiology distinguishes bradykinin-mediated angioedema from IgE-mediated anaphylaxis despite their overlapping clinical presentations (McLendon & Sternard, 2023).1.
