Immune thrombocytopenia (ITP) is a disorder characterized by a low number of platelets (thrombocytes). This affects the blood’s ability to form clots. Without enough platelets, a person with ITP can bleed and bruise easily. In rare cases, bleeding in the brain caused by ITP can be life threatening.
There are two main types of ITP:
The cause of ITP is thought to be an abnormal immune response. Normally, the immune system works to help the body fight off infection and disease. With ITP, the immune system attacks and destroys its own platelets, but the reasons for this are not clearly understood.
ITP is a somewhat common blood disorder. About 5 in every 100,000 children are diagnosed with ITP each year. Routine blood tests can help make the diagnosis. Find out more about immune thrombocytopenia (ITP) on the Together by St. Jude™ online resource.
Some patients may not need treatment other than monitoring platelet counts and watching for signs and symptoms of bleeding. Treatment may be needed if a person’s platelet count is very low or if bleeding problems occur.
Medication is often the first-line treatment for ITP in both children and adults. Medicines may include corticosteroids, such as prednisone. Other medicines include rituximab, intravenous immune globin (IVIG) and anti-Rh (D) immunoglobulin. Some newer drugs, called eltrombopag and romiplostim, can help the body make more platelets.
Platelet transfusions are used to increase the platelet count on a short-term basis.
St. Jude offers clinical trials and research studies for children, teens, and young adults. Learn more about clinical research at St. Jude.
