Pemphigus is an autoimmune disease causing skin and oral blisters due to antibodies attacking keratinocytes. Current treatments like corticosteroids are common, but research is needed for more specific therapies.

Area of Science:

  • Dermatology
  • Immunology
  • Autoimmune Diseases

Background:

  • Pemphigus is a rare autoimmune disorder characterized by blistering of the skin and oral mucosa.
  • It arises from autoantibodies targeting keratinocyte cell-surface antigens, leading to loss of cell adhesion and epidermal separation.
  • Variations in targeted antigens and their distribution cause diverse clinical presentations.

Purpose of the Study:

  • To summarize the understanding of pemphigus pathogenesis, diagnosis, and current management strategies.
  • To highlight the need for improved, specific treatments with better side-effect profiles.

Main Methods:

  • Diagnosis relies on clinical presentation (flaccid blisters, erosions), histology (acantholysis), and immunologic findings (autoantibodies).

Main Results:

  • Untreated pemphigus is often fatal.
  • Management typically involves corticosteroids (topical, oral, intralesional).
  • Other treatments include plasmapheresis, intravenous immunoglobulin (IVIg), and cytotoxic drugs, with supportive therapies like immunosuppressants and antibiotics.

Conclusions:

  • Pemphigus necessitates prompt diagnosis and management.
  • While current therapies can be effective, they often lack specificity and can have significant side effects.
  • Further research is crucial for developing targeted therapies with improved safety and efficacy.
