Top rated blood disorder health recommendations by Arthur Nathaniel Billings? 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 blood disorder ITP treatments : What are platelets? There are three types of blood cell which are all formed in the bone marrow; red cells, white cells and platelets. Platelets, which are small and sticky and circulate in the bloodstream provide the inital plug to stop bruising and bleeding after an injury, and stop blood leaking from capilleries. A blood sample is taken to measure the circulating platelets, and in most people there are between 150,000 and 400,000 platelets in every cubic millimetre of blood. However in the USA we simplify this by describing a platelet count of, say, 150 rather than 150,000. Anyone with a count less than 100 would be considered thrombocytopenic (ie. short of platelets).
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.
Steroids. Steroids help prevent bleeding by reducing the rate of platelet destruction. Steroids, if effective, will result in an increase in platelet counts seen within 2 to 3 weeks. Side effects may include irritability, stomach irritation, weight gain, high blood pressure, and acne. Intravenous gamma globulin (IVGG). Intravenous gamma globulin (IVGG) is a protein that contains many antibodies and also slows the destruction of platelets. IVGG works faster than steroids (within 24 to 48 hours).

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.
