Thrombocytopenic purpura is a bleeding disorder caused by thrombocytopenia, which mainly manifests as significant reduction of platelets and bleeding tendency of skin and organs. Thrombocytopenic purpura is clinically divided into the following three types: idiopathic thrombocytopenic purpura: it is a thrombocytopenic bleeding disorder of unknown cause, which is caused by excessive destruction of platelets by the body’s autoimmune system, resulting in thrombocytopenia, skin bleeding spots, blood oozing from the gums, internal bleeding and other symptoms. Secondary thrombocytopenic purpura: It is mainly caused by impaired platelet production, increased destruction or consumption, and abnormal platelet distribution. Its main symptoms include skin mucous membrane bruises, petechiae, nosebleeds, oral blood blisters, brain hemorrhage, etc. Thrombotic thrombocytopenic purpura: Microvascular endothelial cell damage caused by disease or other reasons, which leads to reduced cellular anti-thrombotic capacity and depletion of platelets. Its main symptoms include purpura, red blood cell damage, and vascular involvement. The treatment of thrombocytopenic purpura is mainly hormone therapy, splenectomy, immune drugs, etc. It is recommended that patients consult the hematology department to improve the blood routine, coagulation function, bone marrow aspiration and other laboratory tests and examinations, and the specialist doctor will make specific treatment plans according to the clinical symptoms and examination results of patients.
