Alopecia areata: pathogenesis and treatment
Journal of the American Academy of Dermatology
|November 1, 1984
Summary
Alopecia areata likely has an autoimmune cause, with genetics and stress potentially playing roles. Newer treatments offer hope for extensive disease, though cures remain elusive.
Area of Science:
- Immunology
- Dermatology
- Genetics
Background:
- Alopecia areata (AA) is a condition with an unknown cause.
- Growing evidence suggests an autoimmune basis for AA.
- Contributing factors may include genetics, atopy, and psychological stress.
Purpose of the Study:
- To review the immunological data related to alopecia areata.
- To examine the roles of genetics, atopy, and psychological stress in AA.
- To discuss current and emerging treatment options for AA.
Main Methods:
- Literature review of immunological studies on alopecia areata.
- Analysis of genetic and environmental factors implicated in AA.
- Evaluation of current and novel therapeutic approaches for AA.
Main Results:
- Significant immunological data support an autoimmune pathogenesis for AA.
- Genetics, atopy, and psychological stress are considered potential contributing factors.
- Current treatments are largely palliative, but new therapies show promise.
Conclusions:
- An autoimmune process is strongly implicated in the pathogenesis of alopecia areata.
- While the exact etiology is still unknown, contributing factors are being identified.
- Emerging therapies like photochemotherapy and immunotherapy offer hope for managing extensive alopecia areata.
