What reason does psoriasis come on

Reason 1: a considerable number of patients have a family history of disease, and some families have obvious genetic tendency. Generally speaking, about 30% of them have family history. The incidence rate varies widely among different races. Psoriasis is a polygenic genetic disease with the interaction of genetic factors and environmental factors. The occurrence rate of some HLA antigens in patients with this disease was significantly increased. Psoriasis may overlap with other diseases (such as rheumatoid arthritis, atopic dermatitis, etc.). Most patients with psoriasis are caused by family relationship, for example, genetic history, if someone in the family has suffered from psoriasis, then the genetic disease rate is as high as 80%.

Reason 2: many scholars have confirmed that streptococcal infection is related to the pathogenesis and course of psoriasis from humoral immunity (anti streptococcal group), cellular immunity (peripheral blood and skin lesions T cells), bacterial culture and treatment. In patients with psoriasis, Staphylococcus aureus infection can aggravate skin lesions, which is related to the superantigen of Staphylococcus aureus exotoxin. Although the occurrence of this disease is related to the infection of virus (such as HIV) and fungus (such as Malassezia), its exact mechanism has not been confirmed. There are also some people suffering from psoriasis, it may be caused by infection factors, if allergic to the outside world, it is easy to lead to psoriasis.

Reason 3: a large number of studies have proved that psoriasis is an immune-mediated inflammatory skin disease, and its pathogenesis is related to inflammatory cell infiltration and inflammatory factors. The skin lesions of some female patients were alleviated or even disappeared after pregnancy, and aggravated after delivery. Psychoneurologic factors are related to the pathogenesis of psoriasis. Drinking, smoking, drugs and mental stress may induce psoriasis. In clinical medicine, the possibility of psoriasis caused by these reasons is not very big, if the long-term psychological hint of patients with psoriasis is too big, then it is easy to lead to psoriasis.
