An individualized diagnostic approach based on guidelines for chronic urticaria (CU)

Area of Science:

• Dermatology
• Allergology
• Immunology

Background:

• Chronic urticaria (CU) is characterized by hives and/or angioedema for ≥6 weeks, significantly reducing patient quality of life (QoL).
• Despite international guidelines, managing CU is complex due to diverse subtypes, multiple causes, and triggers, often co-occurring in single patients.
• Individualized patient assessment presents challenges for clinicians managing chronic urticaria.

Purpose of the Study:

• To review current guidance on the classification, diagnosis, and assessment of chronic urticaria (CU) subtypes.
• To discuss the practical application of patient assessment tools and laboratory tests in clinical practice.
• To support the development of individualized patient management plans for chronic urticaria.

Main Methods:

• Literature review of recent international urticaria guidelines.
• Synthesis of information on CU classification, diagnostic approaches, and assessment tools.
• Discussion of laboratory tests relevant to CU diagnosis and management.

Main Results:

• Recent guidance provides frameworks for classifying and diagnosing various CU subtypes.
• Patient assessment tools and laboratory tests are available to aid in individualized diagnosis.
• Effective management requires a tailored approach considering specific patient factors and triggers.

Conclusions:

• Accurate classification and diagnosis of CU subtypes are crucial for effective management.
• Utilizing available assessment tools and tests facilitates personalized patient care.
• An individualized management plan improves outcomes for patients with chronic urticaria.
