What is vasculitis?
Vasculitis is a common inflammatory disease of blood vessels that has received widespread attention in recent years due to the popularity of health topics. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce in detail the definition, symptoms, causes, treatment methods and preventive measures of vasculitis, and present relevant information in structured data.
1. Definition of vasculitis
Vasculitis, also known as vasculitis, refers to a type of disease in which an inflammatory reaction occurs in the blood vessel wall. Inflammation can involve arteries, veins, or capillaries, causing vessel stenosis, occlusion, or rupture, which can lead to tissue ischemia or bleeding. There are many types of vasculitis, which can be divided into large vessel vasculitis, medium vessel vasculitis and small vessel vasculitis according to the size and location of the affected blood vessels.
| Types of vasculitis | Main blood vessels involved | common diseases |
|---|---|---|
| Large vasculitis | Aorta and its main branches | Giant cell arteritis, Takayasu arteritis |
| vasculitis | medium arteries | Polyarteritis nodosa, Kawasaki disease |
| small vessel vasculitis | arterioles, capillaries, venules | Henoch-Schonlein purpura, microscopic polyangiitis |
2. Symptoms of vasculitis
Symptoms of vasculitis vary depending on the blood vessel involved, but common symptoms include:
| Symptom Category | Specific performance |
|---|---|
| systemic symptoms | Fever, fatigue, weight loss, loss of appetite |
| skin symptoms | Rash, purpura, ulcer, nodule |
| joint symptoms | joint pain, swelling |
| neurological symptoms | Headache, dizziness, numbness or weakness in limbs |
| Other symptoms | Blurred vision, abdominal pain, hematuria |
3. Causes of vasculitis
The cause of vasculitis is not fully understood, but it is currently believed to be related to the following factors:
1.immune abnormalities: Abnormal autoimmune reaction is the main pathogenesis of vasculitis. The immune system mistakenly attacks the blood vessel wall, causing inflammation.
2.Infectious factors: Certain viral or bacterial infections may trigger vasculitis, such as hepatitis B virus associated with polyarteritis nodosa.
3.genetic factors: Some patients with vasculitis have a family hereditary tendency, and specific gene mutations may increase the risk of the disease.
4.environmental factors: Vasculitis may be induced by smoking, drug or chemical exposure.
4. Treatment methods for vasculitis
The goals of treatment for vasculitis are to control inflammation, relieve symptoms, and prevent complications. Treatment plans will depend on the specific type and severity of the condition:
| Treatment | Applicable situations | Commonly used drugs or methods |
|---|---|---|
| drug treatment | Mild to moderate vasculitis | Glucocorticoids (such as prednisone), immunosuppressants (such as cyclophosphamide) |
| biologics | refractory vasculitis | Rituximab, tocilizumab |
| surgical treatment | Severe stenosis or occlusion of blood vessels | Angioplasty, bypass surgery |
| supportive care | adjuvant treatment | Painkillers, anti-infectives, nutritional support |
5. Preventive measures for vasculitis
Although vasculitis cannot be completely prevented, the following steps can reduce the risk or make the condition less severe:
1.healthy lifestyle: Stop smoking and limit alcohol consumption, eat a balanced diet, exercise moderately, and enhance immunity.
2.control infection: Treat infectious diseases promptly to avoid inducing vasculitis.
3.Regular physical examination: Especially people with a family history or autoimmune disease should check their vascular health regularly.
4.Take medication as directed by your doctor: Avoid drug abuse, especially drugs that may cause vasculitis.
