  Immune thrombocytopenic purpura definition - Medical Dictionary definitions of popular medical terms
Immune thrombocytopenic purpura: A blood disorder characterized by the destruction of blood platelets due to the presence of antiplatelet autoantibodies.
Purpura pertains to the visible hallmarks: purplish areas in the skin and mucous membranes (such as the mouth lining) where bleeding has occurred as a result of decreased platelets.
Immune thrombocytopenic purpura (ITP) can be triggered by drugs, or associated with infection, pregnancy, or immune disorders such as systemic lupus erythematosus.

 What Is Idiopathic Thrombocytopenic Purpura?
Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder in which the blood does not clot as it should.
Thrombocytopenic (throm-bo-cy-toe-PEE-nick) means there is a lower-than-normal number of platelets in the blood.

 ITP (idiopathic thrombocytopenic purpura, immune thrombocytopenic purpura) : What is ITP?   (Site not responding. Last check: 2007-09-21)
In a nutshell, ITP (an abbreviation for "idiopathic thrombocytopenic purpura") is a disease that kills platelets.
ITP triggers the immune system to mark platelets as foreign, and subsequently to destroy them in the spleen or, sometimes in the liver.
ITP is generally not fatal; however, extreme cases may be life-threatening because of a risk of spontaneous hemorrhages, internal bleedings and hard-to-stop bleedings that might be caused by injuries.

In ITP, immune system antibodies mysteriously begin to attack and destroy blood platelet cells.
Up till now, ITP patients have typically turned to powerful drugs such as corticosteroids or intravenous immune globulin, which work by inhibiting platelet destruction.
For some ITP patients splenectomy (surgical removal of the spleen) is another treatment option.

 Summary of Immune Thrombocytopenic Purpura
ITP is a bleeding disorder that can lead to bruising and bleeding that is hard to stop.
ITP is caused by a low number of platelets in the blood.
ITP is not the only cause of low platelets (thrombocytopenia), so diagnosis includes ruling out other possible causes of low platelets.

 Immune Thrombocytopenic Purpura
Immune indicates that the illness is caused by the immune system, which makes cells and antibodies that attack the person's own platelets —; the parts of the blood that help the blood to clot.
Purpura means that the illness produces a red or purple rash that is caused by bleeding under the skin.
ITP does not cause symptoms as long as your platelet count remains above 50,000, which usually is the minimum needed to prevent abnormal bleeding.

ITP is thus a type of auto (self) immune disorder.
The risk of serious bleeding in childhood ITP is very small, and usually no treatment is necessary other than avoidance of Aspirin or Ibuprofen, which increase the risk of bleeding.
This is usually achieved by either a short course of steroid drugs (by mouth or, occasionally, by intravenous drip) which suppress the immune system, or an intravenous injection of large amounts of human, soluble antibody protein from blood donors (intravenous immunoglobulin) which interfere with the destruction of platelets by the immune system.

Background: Immune thrombocytopenic purpura (ITP) is a clinical syndrome in which a decreased number of circulating platelets (thrombocytopenia) manifests as a bleeding tendency, easy bruising (purpura), or extravasation of blood from capillaries into skin and mucous membranes (petechiae).
In adults, thrombocytopenic purpura may be a manifestation of systemic lupus erythematosus or acute or chronic leukemia.
Immune destruction of immunoglobulin-coated platelets is mediated by macrophage immunoglobulin G Fc (Fc gamma RI, Fc gamma RII, and Fc gamma RIII) and complement receptors (CR1, CR3).

Background: Idiopathic thrombocytopenic purpura (ITP), also known as primary immune thrombocytopenic purpura and autoimmune thrombocytopenic purpura, is defined as isolated thrombocytopenia with normal bone marrow and the absence of other causes of thrombocytopenia.
ITP is a decrease in the number of circulating platelets in the absence of toxic exposure or a disease associated with a low platelet count.

ITP (Idiopathic thrombocytopenic purpura) is a disorder of blood platelets, a circulating fragment of blood cells responsible for ensuring that our blood coagulation system responds appropriately to blood vessel injury by helping blood clots form.
Patients with ITP often have circulating antibodies directed against their platelets, in a manner analogous to patients with Graves' disease (GD) that have antibodies directed against their thyroid gland.
