What is the initial treatment for idiopathic thrombocytopenic purpura (ITP)?

The initial treatment for idiopathic thrombocytopenic purpura (ITP) is corticosteroids. This approach is based on the understanding that ITP is characterized by an autoimmune response that leads to the destruction of platelets. Corticosteroids help by dampening this immune response and reducing the destruction of platelets, ultimately leading to an increase in platelet counts.

Corticosteroids, such as dexamethasone or prednisone, are often the first-line therapy because they are readily available and can be effective in increasing platelet levels quickly. They are generally well tolerated and can be used to stabilize patients with low platelet counts while further assessments or treatments are considered.

Other therapies might be indicated for patients who do not respond to corticosteroids. For instance, IVIG can be used as a second-line treatment option, particularly in situations where an immediate increase in platelet count is required, such as prior to surgery. However, it is not typically the first choice for initial management in ITP. Bone marrow transplant, while a potential treatment for severe or refractory cases, is not a first-line option due to its invasive nature and the associated risks. Anticoagulants are contraindicated in ITP due to the risk of bleeding and would not be used
