What is allergic purpura?

Henoch-Schonlein purpura is a common skin disease. Some people are prone to redness and itching in their lives. This is allergic purpura. Let me share with you what allergic purpura is.

1. First of all, Henoch-Schonlein purpura, also known as Henoch-Schonlein purpura, is an allergic vasculitis that invades arterioles and capillaries of skin and other organs, often accompanied by abdominal pain, joint pain and kidney damage, but the number of platelets that stop bleeding is not small.

2. Then it may be related to streptococcus infection, virus infection, drugs, food, insect bites, etc. The mechanism is that the immune complex formed by the combination of antigen and antibody is deposited on the blood vessel wall, activating complement, leading to inflammation in and around the walls of capillaries and small blood vessels, increasing the permeability of blood vessel walls, and various problems will occur.

Finally, this disease usually occurs in children. At first, there may be symptoms such as fever, headache, joint pain and general malaise. Skin lesions are characterized by petechiae, ecchymosis or urticaria-like rash from needle to soybean. In severe cases, blisters, blood blisters and even ulcers may appear. It often occurs on the extended side of limbs, especially on the lower limbs and buttocks.

Matters needing attention

Purpura patients should not eat irritating food, drink plenty of water, and do not take a bath with a bath towel. When it itches, everyone needs to scratch it slowly. If the skin is not clean or the hands are not clean, it is easy to cause fungal infection.
