Common causes of psoriasis

summary

Psoriasis is a common skin disease, but it is difficult to treat psoriasis. My cousin has been suffering from psoriasis for more than two years. There are several white plaques on her arm. When these plaques are serious, there will be peeling and bleeding. Today, I'd like to share with you the causes of common psoriasis .

Common 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.

matters needing attention

Due to the high pressure of work and mental stress in daily life, a series of psychological or physiological reactions can occur, which can promote neuroendocrine disorders, endanger the body's immune protection system, and metabolic disorders of some enzymes, and then promote the attack of psoriasis.
