How is psoriasis caused

summary

In clinical practice, the emergence of psoriasis is actually related to many factors, and genetics is one of them. Therefore, this paper makes the following analysis on how psoriasis causes problems.

How is psoriasis caused

Factor one: heredity. When most people suffer from psoriasis, its etiology is mostly related to familial inheritance. It is generally believed that about 30% of them have a 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.).

Factor 2: infection. 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.

Factor 3: abnormal immunity. 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.

matters needing attention

Psoriasis patients should pay attention to wearing clean and soft clothes in their daily life after they have a clear understanding of their causes.
