Area of Science:

  • Dermatology
  • Immunology
  • Autoimmune diseases

Context:

  • Pemphigus is a rare autoimmune bullous disease affecting the skin and mucosae.
  • It can be triggered by genetic, environmental, or drug-related factors.
  • The disease often presents with painful oral erosions and flaccid blisters.

Purpose:

  • To describe the clinical presentation, diagnosis, and treatment of pemphigus.
  • To highlight the role of autoantibodies in keratinocyte adhesion loss.
  • To discuss the improved prognosis with modern therapies.

Summary:

  • Pemphigus is characterized by intraepidermal cleavage and acantholysis, confirmed by direct immunofluorescence showing immunoglobulin and complement deposits.
  • Autoantibodies target epidermal cell junction zone antigens, leading to keratinocyte loss of cohesion.

  • Circulating antibody titers correlate with disease activity.

    • Impact:

    • Systematic corticosteroid therapy, often combined with immunosuppressants, has transformed the prognosis of pemphigus.
    • Understanding the autoimmune mechanisms aids in developing targeted therapies.
    • Improved management strategies reduce morbidity and mortality associated with this condition.
