Pulmonary vasculitis.

R Y Leavitt, A S Fauci

    The American Review of Respiratory Disease
    |July 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    Pulmonary vasculitis, including granulomatous conditions like Wegener's, often affects the lungs. Ruling out infections is crucial; effective treatments combine immunosuppressants and corticosteroids, yielding high survival rates.

    Area of Science:

    • Pulmonary Medicine
    • Rheumatology
    • Pathology

    Background:

    • Granulomatous vasculitides frequently involve the lungs, encompassing conditions such as Wegener's granulomatosis.
    • Necrotizing sarcoid granulomatosis is a pulmonary vasculitis, distinct from systemic vasculitis.
    • Infectious agents can mimic pulmonary vasculitis, necessitating their exclusion for accurate diagnosis.

    Purpose of the Study:

    • To review the spectrum of pulmonary vasculitis.
    • To highlight diagnostic considerations, particularly differentiating vasculitis from infections.
    • To outline current therapeutic strategies and outcomes for pulmonary vasculitis.

    Main Methods:

    • Literature review of granulomatous vasculitides and pulmonary vasculitis.
    • Discussion of differential diagnoses, focusing on infectious mimics.

  • Summary of treatment approaches for various forms of pulmonary vasculitis.

    • Main Results:

    • Pulmonary vasculitis includes Wegener's granulomatosis, allergic angiitis, and polyangiitis overlap syndrome.
    • Pulmonary capillaritis can lead to pulmonary hemorrhage.
    • Hypersensitivity vasculitides require antigen removal and corticosteroid therapy.
    • Systemic vasculitides treated with cyclophosphamide and corticosteroids show a 5-year survival of approximately 90%.

    Conclusions:

    • Accurate diagnosis of pulmonary vasculitis requires excluding infectious etiologies.
    • Treatment strategies vary based on the underlying cause, ranging from antigen removal to immunosuppression.
    • Combination therapy for systemic vasculitis offers a high survival rate, underscoring treatment efficacy.
