Sarcoidosis. An updated review.

F A Kerdel, S L Moschella

    Journal of the American Academy of Dermatology
    |July 1, 1984
    PubMed
    Summary

    Sarcoidosis is a multisystem disease causing granulomas, often affecting lungs, lymph nodes, skin, and eyes. Activated T-helper cells in affected tissues may drive granuloma formation, with corticosteroids being the most effective treatment.

    Area of Science:

    • Immunology
    • Pathology
    • Pulmonology

    Background:

    • Sarcoidosis is an idiopathic multisystem disease characterized by noncaseating granulomas.
    • It commonly affects the lungs, lymph nodes, skin, and eyes.
    • Associated immune dysregulations include polyclonal hyperglobulinemia and depressed cell-mediated immunity.

    Purpose of the Study:

    • To elucidate the pathophysiology of sarcoidosis.
    • To understand the role of cellular interactions in disease development.
    • To identify key factors in granuloma formation.

    Main Methods:

    • Analysis of cellular composition in sarcoid-involved tissues.
    • Investigation of cellular interactions contributing to sarcoidosis.
    • Review of immunologic aberrations in affected patients.

    Main Results:

    • Activated T-helper cells predominate in affected tissues during early stages.
    • These T-helper cells may produce macrophage chemotactic substances, initiating granuloma formation.
    • The disease course is variable, with acute forms often resolving spontaneously.

    Conclusions:

    • Activated T-helper cells play a crucial role in sarcoidosis pathophysiology.
    • Understanding cellular mechanisms offers insight into granuloma formation.
    • Systemic corticosteroids remain the primary effective treatment for sarcoidosis.
