the biggest feature is that it rises quickly and disappears quickly. Suddenly, it rises a lot. After a few hours, the place where it started is gone, and it starts again in other places. According to this feature, most people have had it once, and I am sure I will know it at first sight in my life.
There are many types of urticaria, some of which are caused by allergies. We can only find the allergic factors and remove them. Some are caused by infections and some are caused by autoimmune diseases. There are indeed some urticaria. So far, the causes have not been found in medicine, and a small number of patients with urticaria can be cured.
The treatment of urticaria doesn't necessarily take a long time. acute urticaria, who just got it, can get well within two weeks, 8% of whom don't get well within two weeks. After more than one month, it becomes chronic urticaria, half of which can get well within one year, and the rest may get well within three or five years after one year, so it is more stubborn. What I just said was that there was no etiological examination, that is to say, I went to the hospital for a little allergy, and there was no symptomatic examination. The result was like this. Now we are all examining patients. After the examination, more patients may be cured in the future.
treatment of chronic urticaria
chronic urticaria is a skin disease with unknown etiology, long course and difficult treatment, among which chronic idiopathic urticaria (CIU) is a type that seriously affects the quality of life. Studies in recent 1 years show that a large proportion of CIU patients are determined to be caused by autoimmunity. At present, the treatment of chronic urticaria is still based on symptomatic treatment, and the treatment goal is to relieve symptoms quickly and permanently. Many drug and non-drug interventions are valuable, but they are not generally successful. The choice of treatment should be individualized.
1 Non-drug treatment: In a few cases, the cause of chronic urticaria can be found, and the treatment must be directed at its cause. Aggravating factors can be determined from the medical history, such as heat, tight clothes, stress reaction, alcohol, etc., and the induced stimulation of physical urticaria should be avoided as much as possible. If there are clear causes, preventive measures should be advised. For example, patients with cold urticaria should cover their exposed skin. Symptomatic treatment such as cholinergic urticaria should be cool, and it is helpful to bathe with hot water when cold urticaria occurs. It is suggested that aspirin and other non-steroidal anti-inflammatory drugs should not be used, because these drugs can stimulate chronic urticaria in about 3% patients, and acetaminophen is recommended. It has been recognized for many years that food-borne pseudoallergens include food pigments, preservatives and natural salicylates.
2 drug therapy
(1) First-line treatment drugs Antihistamines are the main treatment drugs for chronic urticaria, which can reduce itching and wheal.
(2) Second-line treatment drugs:
Corticosteroid hormone: When adequate antihistamines are ineffective for chronic urticaria, oral corticosteroids are occasionally needed to shorten the symptoms.
Epinephrine: It can be directly inhaled with epinephrine to treat vascular edema of lip mucosa, which can achieve certain curative effect.
thyroxine: When thyroid autoimmunity occurs in CIU patients, thyroid autoantibodies are positive, so thyroxine can be used for treatment.
leukotriene receptor antagonist: it is difficult to treat chronic urticaria with antihistamines alone, and often satisfactory results can not be obtained. Montelukast is a leukotriene receptor antagonist.
sulfapyridine can be used for the treatment of chronic urticaria and delayed stress urticaria
Others: colchicine, hydroxychloroquine, dapsone and indomethacin are obviously effective in treating urticaria vasculitis.
(3) Third-line therapeutic drugs: immunosuppressants.
Of course, medication must be used under a doctor's prescription.
