Arthur Nathaniel Billings blood disorder solutions today? What is ITP? Immune thrombocytopenia (formerly known as idiopathic thrombocytopenic purpura) is a medical term for an autoimmune disorder (immune) causing a shortage of platelets (thrombocytopenia) and bruising (purpura). What is the cause of ITP? ITP is an autoimmune disease in which the immune system mistakes the platelets as being foreign and destroys them. It can follow a virus, vaccination or certain medications, but for most people the cause is unknown.

Arthur Nathaniel Billings on ITP blood disorder treatments : What is the incidence of ITP? In the USA about 3,000 to 4,000 of the population have ITP at any one time, and it is not more prevalent in any particular racial or ethnic group. What are the symptoms of ITP? Some people with ITP, especially those with a count over 50, may have no symptoms at all, and their ITP only noticed during a routine blood test. Even people with very low counts, can sometimes have few symptoms.

Diagnosis of ITP: There is no single blood test that can prove you have ITP, and it remains a diagnosis of exclusion based on history, examination and the results of your initial tests. Investigations are mainly blood tests and are focused on looking for underlying causes of low platelets (other causes for low platelets include vitamin deficiencies, medication, or a bone marrow abnormality). If there are any unusual features on initial tests, we may recommend a bone marrow examination, which is a day unit procedure where we take a small sample of marrow from the pelvic bone under local anaesthetic.

Careful review of your medications: Historically, a bone marrow aspiration was required to make a diagnosis of ITP. It may not be absolutely necessary in the face of a positive antiplatelet antibody test, but it is still commonly done to look at the production of platelets and to rule out any abnormal cells the marrow may be producing that could lower platelet counts. A bone marrow aspiration is necessary for a diagnosis if the antiplatelet antibody testing is negative. See additional details on Arthur Billings.

Chronic thrombocytopenic purpura. The onset of the disorder can happen at any age, and the symptoms can last a minimum of 6 months, several years, or a lifetime. Adults have this form more often than children do, but it does affect adolescents. Females have it more often than males. Chronic ITP can recur often and requires continual follow-up care with a blood specialist (hematologist). What causes idiopathic thrombocytopenic purpura? In ITP, the immune system is stimulated to attack your body’s own platelets. Most often this is a result of antibody production against platelets. In a small number of cases, a type of white blood cell called T-cells will directly attack platelets. This immune system error may be a result of any of the following.
