Patient at risk of anaphylaxis

The clinical status designated as a patient at risk of anaphylaxis refers to individuals predisposed to acute, severe, and potentially fatal systemic hypersensitivity reactions upon exposure to specific triggers This population commonly includes pediatric and adult patients with a documented history of severe allergic reactions, comorbid asthma, underlying mast cell disorders, or confirmed sensitization to common elicitors such as foods, insect venoms, medications, or latex

This population commonly includes pediatric and adult patients with a documented history of severe allergic reactions, comorbid asthma, underlying mast cell disorders, or confirmed sensitization to common elicitors such as foods, insect venoms, medications, or latex Pathophysiologically, accidental allergen re-exposure triggers rapid, typically immunoglobulin E-mediated degranulation of mast cells and basophils, releasing massive amounts of histamine, tryptase, and other vasoactive mediators

This explosive systemic response can cause multi-organ compromise, marked clinically by sudden mucosal or cutaneous involvement, acute bronchospasm, upper airway angioedema, gastrointestinal distress, and profound cardiovascular collapse or shock
