Summary

Aspirin-induced asthma (AIA) involves NSAID hypersensitivity and leukotriene overproduction. Patients with AIA should avoid COX-1 inhibitors but can often safely use COX-2 inhibitors like coxibs.

Area of Science:

  • Pulmonology
  • Clinical Immunology
  • Pharmacology

Background:

  • Asthma incidence is rising globally, posing public health and economic challenges.
  • Aspirin-induced asthma (AIA) is a specific syndrome where cyclooxygenase (COX)-1 inhibiting NSAIDs worsen asthma.
  • AIA is preceded by eosinophilic rhinosinusitis, nasal polyposis, and aspirin hypersensitivity.

Purpose of the Study:

  • To describe the clinical presentation and biochemical characteristics of aspirin-induced asthma.
  • To highlight diagnostic challenges and management strategies for AIA.
  • To review the safety and tolerability of alternative analgesics in AIA patients.

Main Methods:

  • Diagnosis relies on characteristic symptoms and aspirin provocation tests, as no in vitro test exists.

  • Biochemical analysis reveals chronic overproduction of cysteinyl leukotrienes and overexpression of leukotriene C4 synthase.
  • Genetic polymorphism of leukotriene C4 synthase may contribute to AIA pathogenesis.
  • Main Results:

    • AIA often follows a severe, protracted course, frequently requiring systemic corticosteroids.
    • Patients must avoid aspirin and other COX-1 inhibitors to prevent severe reactions.
    • Paracetamol shows low cross-sensitivity, and COX-2 inhibitors (coxibs) are generally well-tolerated.

    Conclusions:

    • AIA is characterized by eosinophilic inflammation and leukotriene pathway dysregulation.
    • Strict avoidance of COX-1 inhibitors and careful consideration of alternative analgesics are crucial for AIA management.
    • Specific COX-2 inhibitors offer a safer alternative for pain management in patients with AIA.
