The clinical symptoms of vasculitis are complex and varied, mainly including systemic symptoms such as malaise, fever, joint and muscle pain, and organ involvement manifestations such as rash and cough. Symptoms of vasculitis may vary depending on the type of blood vessel involved and the organ involved. On the one hand, there may be systemic symptoms caused by inflammation, such as fever, malaise, joint and muscle pain, and weight loss. On the other hand, vascular lesions may lead to ischemia and abnormal function of the organs, such as skin rash when the skin is involved, cough, sputum, hemoptysis, dyspnea and other symptoms when the lungs are involved, proteinuria, hematuria, hypertension, etc., and headache, vertigo, and altered consciousness when the nervous system is involved. In order to avoid irreversible organ damage in patients with vasculitis, it is recommended that they should go to the rheumatology and immunology department of the hospital as soon as possible, and can use glucocorticosteroids such as methylprednisolone, prednisone acetate and other immunosuppressant drugs such as cyclophosphamide and azathioprine under the guidance of the doctor, and plasma exchange and static injection of high-dose immunoglobulin can be used to alleviate the condition if necessary.
