Etiology of psoriasis

summary

My cousin has been suffering from psoriasis for some time. There are several white plaques on her arm. When these plaques are serious, there will be symptoms of peeling and bleeding. Patients with psoriasis should be treated as soon as possible. Now I will tell you the cause of psoriasis.

Etiology of psoriasis

First, it is generally believed that the disease is autosomal dominant with incomplete penetrance. It is reported that 10% - 23.8% of the patients have family history in China. The prevalence rate of family disease is much higher than that of the general population.

Second: infection with bacteria is also one of the causes of diseases. Streptococcus is the most likely bacteria to cause our diseases, and this kind of bacteria is everywhere in our daily life. It is impossible for us to completely avoid it. The best thing is to increase the body's resistance to bacteria, so that bacteria can not invade the body.

Third, it has been found that the keratin extract of psoriasis vulgaris and pustular psoriasis contains complement component C3a, which can make neutrophils aggregate to lesions and form micro abscess. T lymphocyte infiltration exists in the dermis of psoriasis. Activated T lymphocytes release cytokines to stimulate the proliferation of keratinocytes.

matters needing attention

Patients with psoriasis should go to the regular hospital for examination and treatment as soon as possible, and timely correct the bad living habits. Because of work pressure and mental stress, they can have a series of psychological or physiological reactions, promote neuroendocrine disorders, endanger the body's immune protection system, and some enzyme metabolic disorders, and then promote the attack of psoriasis.
