Chronic urticaria and angioedema significantly impact life quality. Recent European guidelines offer standardized classification and trigger identification, improving diagnosis and management of these complex conditions.

Area of Science:

  • Dermatology
  • Allergy and Immunology
  • Internal Medicine

Background:

  • Urticaria and angioedema are prevalent conditions, often chronic, leading to prolonged suffering and reduced quality of life.
  • A lack of standardized nomenclature and diagnostic classification hinders understanding of disease etiology, pathogenesis, and clinical trial comparability.

Purpose of the Study:

  • To address the need for international agreement on urticaria and angioedema nomenclature and classification.
  • To review recent European guidelines aimed at standardizing diagnosis and management.

Main Methods:

  • Review of recently published European guidelines for urticaria and angioedema.
  • Identification of diagnostic criteria, potential triggers, and treatment approaches.

Main Results:

  • European guidelines have established a consensus on nomenclature and classification for urticaria and angioedema.
  • Key diagnostic steps include defining urticaria subtype, seeking triggers (infections, pseudoallergies, autoreactivity), and considering autologous serum tests.
  • Trigger avoidance/eradication is the most effective treatment; H1 antihistamines are the mainstay, with dose escalation for severe cases.

Conclusions:

  • Standardized classification and trigger identification are crucial for understanding and managing urticaria and angioedema.
  • While H1 antihistamines are primary treatment, evidence for alternatives is limited, necessitating careful risk-benefit assessment for off-label use.
