Allergic vasculitisDefinition Allergic vasculitis is hypersensitivity to a drug or foreign agent that leads to inflammation and damage to blood vessels of the skin. Causes, incidence, and risk factors Vasculitis occurs because of inflammation and damage to blood vessels. The inflammation of allergic vasculitis is the result of an allergic reaction to a drug or other foreign agent. Symptoms
Signs and tests The diagnosis is primarily based on a history of skin lesions that develop after exposure to medications or a foreign substance (antigen ) and the pattern of symptoms.
Treatment Treatment is aimed at reducing the inflammation, allowing the natural healing process to occur. If possible, stop exposure to the causative medication (or other antigen). Aspirin or corticosteroids may be prescribed to reduce inflammation of the blood vessels. (DO NOT give aspirin to children except as advised by the health care provider.) In severe cases, treatment with corticosteroids may be necessary. Expectations (prognosis) Allergic vasculitis usually resolves in time. Complications
Calling your health care provider Call for an appointment with your health care provider if symptoms indicate allergic vasculitis may be present. Prevention Avoid exposure to medications to which there are known allergies. Illustrations
