Nowadays, it is mostly called immune thrombocytopenic purpura. I. What is idiopathic thrombocytopenic purpura Platelets are a type of cell in the human blood, and its function is to prevent bleeding. In some people, antibodies that destroy platelets are produced, so that platelets are destroyed and thrombocytopenia occurs, and this disease is called idiopathic thrombocytopenic purpura. Idiopathic thrombocytopenic purpura: Although idiopathic thrombocytopenic purpura is a disease of unknown etiology, clinical workers have found that the following factors are related to the occurrence and aggravation of the disease: immune factors: immune dysfunction is the primary factor. Infection: Many patients, especially pediatric patients, often develop the disease after an upper respiratory tract infection, and patients with the original disease relapse or worsen after infection. Pregnancy: some pregnant women are prone to idiopathic thrombocytopenic purpura, which can be self-healed or cured after delivery, and is prone to recurrence after another pregnancy. The manifestations of idiopathic thrombocytopenic purpura: Bleeding: skin bleeding spots, purpura, gum bleeding, nasal bleeding, excessive menstruation, internal bleeding and intracranial bleeding occur in severe cases. Blood test: thrombocytopenia is found. Treatment of idiopathic thrombocytopenic purpura: Glucocorticoid therapy is the first choice, about 90% of patients can recover normal platelets after regular treatment. For patients with severe platelet reduction, platelet transfusion and high-dose gammaglobulin drip are required. About 10% of patients have difficulty in normalizing their platelets despite active treatment and become refractory idiopathic thrombocytopenic purpura. For refractory cases, splenectomy and immunosuppressant (cyclophosphamide, cyclosporine A, etc.) treatment can be adopted. In recent years, rituximab has been used at home and abroad to treat refractory idiopathic thrombocytopenic purpura with satisfactory results.
