Office-based management of urticaria

Area of Science:

• Dermatology
• Immunology

Background:

• Urticaria is a prevalent pruritic skin disorder with variable severity and duration.
• The exact cause of urticaria is often elusive.
• Triggers can include physical factors, foods, and medications.

Purpose of the Study:

• To summarize the understanding of urticaria's pathophysiology and management.
• To highlight the role of autoantibodies and mast cell activation in chronic urticaria.
• To outline current and alternative treatment strategies.

Main Methods:

• Review of existing literature on urticaria.
• Discussion of diagnostic approaches, including identification of triggers.
• Analysis of pharmacotherapeutic options.

Main Results:

• A significant portion of chronic urticaria patients exhibit autoantibodies against immunoglobulin-E (IgE) or its receptor (FcεRI).
• Antithyroid antibodies may contribute to mast cell activation, a key pathway in urticaria.
• Antihistamines are effective for symptomatic relief in most cases.

Conclusions:

• Management involves identifying and eliminating triggers, alongside treating underlying conditions.
• For severe chronic urticaria, advanced therapies like corticosteroids, hydroxychloroquine, and immunosuppressants may be considered.
• Understanding the immunological basis of urticaria guides treatment decisions.
