Vasculitis is a systemic disease that involves the blood vessels of the entire body, and all organs of the body may be affected by it. If the cause of the vasculitis is clear, the vasculitis is secondary to the primary disease, and the systemic symptoms are mild and do not invade important organs, only some joint pain, weakness, anorexia, fever and rash symptoms, glucocorticoids and immunosuppressants can be used to control the symptoms. On this basis, if the primary disease, such as systemic lupus erythematosus and rheumatoid arthritis, is actively controlled, then the vasculitis can be improved or even cured. If the vasculitis is primary vasculitis, no clear cause can be found, and it has invaded important organs of the body, such as kidney, lung, digestive system, brain, etc., affecting the function of organs, and kidney failure, digestive bleeding, brain bleeding, etc., it may be life-threatening. Therefore, it is not possible to cure the disease during the treatment process, but only to control the symptoms to get better and avoid further development of the disease. In addition, there are many causes of vasculitis, such as allergies or connective tissue diseases, which can be alleviated by controlling the original disease. However, in the case of vasculitis caused by malignant tumors, the cause is difficult to eradicate and therefore vasculitis is more difficult to control and may be complicated by systemic diseases, such as kidney failure, liver failure, or even heart failure. If such serious complications occur, then vasculitis is very difficult to cure. In summary, whether or not vasculitis can be cured cannot be generalized, but depends on the specific site of onset and systemic damage.
