Examples of Vasculitis in the following topics:

  • Immune Complex Autoimmune Reactions

    • Immune complexes may cause disease when they are deposited in organs, e.g. in certain forms of vasculitis.
    • Typical of most mechanisms of the type III hypersensitivity, Arthus manifests as local vasculitis due to deposition of IgG-based immune complexes in dermal blood vessels.
  • Type III (Immune Complex) Reactions

    • Hence, vasculitis, glomerulonephritis and arthritis are commonly-associated conditions as a result of type III hypersensitivity responses.
    • As observed under methods of histopathology, acute necrotizing vasculitis within the affected tissues is observed concomitant to neutrophilic infiltration, along with notable eosinophilic deposition (fibrinoid necrosis).
    • Immune complexes may themselves cause disease when they are deposited in organs, e.g. in certain forms of vasculitis.
  • The Cardiovascular System

    • Vasculitis is inflammation of the vessel wall due to an infection (or autoimmune disease).
