My friend is suffering from psoriasis. He has several white plaques on his arm. When these plaques are serious, he will have the symptoms of peeling. For patients with psoriasis, he must be treated as soon as possible. Some time ago, he went to the hospital for treatment. The doctor also told us about the cause of psoriasis.

What is the cause of psoriasis

Etiology 1: it is generally considered 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.

Cause 2: bacterial infection 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 avoid it completely. The best thing is to increase the body's resistance to bacteria, so that bacteria can not invade the body.

Etiology 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

Psoriasis patients with this disease should have a persistent attitude to face and treat this disease, and actively treat it. Because of work pressure and mental stress, they can have a series of psychological or physiological reactions, promote neuroendocrine disorders, endanger the immune protection system, and some enzyme metabolic disorders, and then promote the onset of psoriasis.
