Allergy·2019

Chronic urticaria, often idiopathic, may stem from autoimmune factors. Identifying histamine-releasing autoantibodies suggests autoimmune urticaria, potentially benefiting from immunosuppressive therapies when standard treatments fail.

Area of Science:

  • Dermatology
  • Immunology
  • Allergy

Background:

  • Chronic urticaria presents diverse clinical features and etiologies.
  • A significant portion of chronic urticaria cases, previously termed "idiopathic," are now understood to have autoimmune underpinnings.
  • Histamine-releasing autoantibodies are detected in approximately 50% of patients with idiopathic chronic urticaria.

Purpose of the Study:

  • To provide an updated review on the classification, causes, and management of chronic urticaria.
  • To elucidate the role of autoimmune mechanisms in chronic urticaria.
  • To integrate the concept of autoimmune urticaria into current clinical frameworks.

Main Methods:

  • Literature review of recent advances in chronic urticaria research.

  • Analysis of diagnostic criteria and therapeutic strategies for chronic urticaria.
  • Discussion of the immunological basis of autoimmune urticaria.

    • Main Results:

    • Autoimmune urticaria is an emerging and accepted classification for a subgroup of chronic urticaria patients.
    • The presence of histamine-releasing autoantibodies is a key indicator for autoimmune urticaria.
    • Immunosuppressive therapies are a viable option for refractory autoimmune urticaria cases.

    Conclusions:

    • Recent advances highlight the autoimmune basis of a significant subset of chronic urticaria.
    • Recognizing autoimmune urticaria guides the selection of appropriate immunosuppressive treatments.
    • Updated understanding improves the management of complex chronic urticaria cases.
