Causes of psoriasis

summary

Psoriasis has been bothering me for many years. I have a lot of psoriasis on my back. When these white plaques are serious, there will be peeling and bleeding. As for the cause of psoriasis, the doctor also told me when I received treatment. Now I will share the cause with you.

Causes of psoriasis

Cause 1: it is generally believed that the disease is autosomal dominant inheritance 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.

The second cause of disease: bacterial infection is also one of the causes of disease. Streptococcus is the most likely bacteria to cause our disease, 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 resistance of the body to bacteria, so that bacteria can not invade the body.

Cause 3: it has been found that the keratin extract of psoriasis vulgaris and pustular psoriasis contains complement component C3a, which can make neutrophils aggregate to the lesion and form micro abscess. T lymphocyte infiltration exists in the dermis of psoriasis. Activated T lymphocytes release cytokines to stimulate the proliferation of keratinocytes.
