What is the cause of purpura

Reason 1: Henoch Schonlein purpura is a kind of skin vascular inflammation, the disease may be caused by a variety of factors, but the direct cause of Henoch Schonlein purpura is often difficult to determine. Through the investigation of clinical cases, it is found that bacterial and viral infection is the most common cause of allergic purpura. Such as upper respiratory tract inflammation, tonsillitis, pneumonia, scarlet fever, urinary tract infection and other acute infections.

Reason 2: parasitic infection is another common cause of Henoch Schonlein purpura, in which Ascaris is the most common cause, followed by hookworm, whipworm, filariasis, Schistosoma, vaginal Trichomonas, etc. In addition, some foods are also causes of allergic purpura can not be ignored, such as fish, shrimp, milk, eggs and so on. Moreover, some common antibiotics, antipyretic analgesics, sedatives, antituberculosis drugs may induce allergic purpura.

The third reason is autoimmunity. The increase of capillary permeability and fragility caused by allergic reaction to some allergic substances leads to hemorrhage and edema of subcutaneous tissue, mucous membrane and internal organs. Allergens can be caused by many factors, but it is often difficult to find the exact cause of each specific case. It is generally believed that it may be related to many inducing factors But the direct pathogenic factors are often difficult to confirm.
