Idiopathic thrombocytopenia, abbreviated as ITP, is an autoimmune disease in which the patient’s autoimmune function is disturbed and antibodies are produced against his or her own platelets, which bind to the platelet membrane, causing the platelets to be retained and engulfed by mononuclear macrophages in the spleen as they pass through the bloodstream. symptoms. This platelet-associated antibody also binds to the surface of megakaryocytes in the bone marrow, resulting in impaired maturation of megakaryocytes, which in turn does not produce adequate numbers of platelets properly, also exacerbating the reduced number of platelets in the peripheral blood and aggravating the symptoms of bleeding. Therefore, the main cause of idiopathic thrombocytopenia is still an autoimmune disease, and the main clinical treatment is still glucocorticoid therapy, which can reduce the production of antibodies and inhibit the destruction of platelets by the spleen, thus increasing the number of platelets.
