Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder caused by an abnormally low level of blood platelets, small disc-shaped cells essential to blood clotting (coagulation).
Coagulation, or clotting, is a complex process in which specific proteins found in blood plasma combine with other blood components, including platelets, to form clots and prevent blood loss.
A deficiency in platelets or a disorder that affects platelet production can disrupt clotting and severely complicate blood loss from accidental injury, surgery, and specific diseases or conditions in which bleeding can occur.
Coagulation tests, including clotting time, will be performed to determine the ability of the child's blood to form a clot.
Clotting factors-Substances in the blood, also known as coagulation factors, that act in sequence to stop bleeding by triggering the formation of a clot.
Each clotting factor is designated with a Roman numeral I through XIII.
Platelet-A cell-like particle in the blood that plays an important role in blood clotting.
They change shape from round to spiny, "sticking" to the broken vessel wall and to each other to begin the clotting process.
In addition to physically plugging breaks in blood vessel walls, platelets also release chemicals that promote clotting.
Parents are also advised to avoid giving the child aspirin, ibuprofen, or other over-the-counter pain medications because these drugs are known to lengthen the clotting time of blood.
Blood is made up of red blood cells (RBCs), which carry oxygen and other materials to all tissues of the body; white blood cells (WBCs), which fight infection; and platelets, which play a part in the clotting of the blood.
Platelets, which are also called thrombocytes, are small disk-shaped blood cells produced in the bone marrow and involved in the process of blood clotting.

Coagulation disorders (coagulopathies) are disruptions in the body's ability to control blood clotting, an essential function of the body designed to prevent blood loss.
The most commonly known coagulation disorder is hemophilia, a condition in which a critical component of blood coagulation is missing, causing individuals to bleed for long periods of time before clotting occurs.
Coagulation, or clotting, is a complex process (called the coagulation cascade) that involves 12 coagulation factors (designated by Roman numerals as factors I through XII) found in blood plasma and several other blood components.
They also help plug damaged blood vessels and work with other constituents in plasma to accelerate blood clotting.
Deficiency in the vitamin can affect the clotting factor's performance as well as deficiency in the factor itself.
This condition accelerates clotting, which ironically can result in hemorrhage when the clotting factors are exhausted.
Von Willebrand's disease, a hereditary disorder with prolonged bleeding time, is due to a clotting factor deficiency and impaired platelet function.
Hypoprothrombinemia is a congenital deficiency of clotting factors that can lead to hemorrhage.
Disseminated intravascular coagulation (DIC) occurs when the malfunction of clotting factors causes platelets to form clots in small blood vessels throughout the body.
This action leads to depletion of clotting factors and platelets, which are then not available at a site of injury where clotting is needed.
What the underlying causes of DIC have in common is a dysfunction that involves proteins, platelets, or other clotting factors and processes.
For example, uterine tissue can enter the mother's circulation during prolonged labor, introducing foreign proteins into the blood, or the venom of some exotic snakes can activate one of the clotting factors.
Regardless of the specific cause of DIC, the results are a malfunction of thrombin (an enzyme) and prothrombin (a glycoprotein), which activate the fibrinolytic system, releasing clotting factors in the blood.
Von Willebrand's disease is caused by a defect in the von Willebrand clotting factor, often accompanied by a deficiency of factor VIII as well.
Diagnostic blood tests are performed in the clinical laboratory, including assays of the specific clotting factors, to help detect various coagulation disorders.
Hemophilia A is diagnosed with laboratory tests that can detect the presence of clotting factor VIII, factor IX, and others, as well as the presence or absence of clotting factor inhibitors.
Christmas disease involves an investigation of bleeding and clotting times, as well as determining factor IX deficiency.
Hypothrombinemia is diagnosed based on family history and the use of tests that measure vitamin K deficiency, deficiency of prothrombin, and measurements of clotting factors V, VII, IX, and X.
Factor XI deficiency is determined by measuring the specific coagulation factor as well as other coagulation tests including prothrombin time and clotting time.
In mild coagulopathies, treatment may involve the use of drugs that stimulate the release of deficient clotting factors.
In severe cases, bleeding may only stop if the clotting factor that is missing is replaced through infusion of human blood components containing concentrated amounts of specific clotting factors.
Commercial preparations of freeze-dried clotting factors have also made it possible for people to infuse themselves as directed by their physicians.
Severe bleeding episodes require transfusions of human blood clotting factors.
In each type of hemophilia (hemophilias A, B, and C), a critical coagulation protein is missing, causing individuals to bleed for long periods of time before clotting occurs.
In the complex coagulation process, the absence or inactivity of just one clotting factor can greatly increase bleeding time.
In hemophilia, certain clotting factors are either decreased in quantity, absent altogether, or improperly formed, preventing the formation of a clot and resulting in uncontrolled bleeding.
In hemophilia B, or Christmas disease, the deficient clotting factor is factor IX, but the symptoms are very similar to those of hemophilia A.
A deficiency in vitamin K can affect the clotting factor's performance as well as a deficiency in the factor itself.
Some other rare clotting disorders such as von Willebrand's disease present similar symptoms but are not usually called hemophilia.
Gene therapy involves sophisticated methods of transferring new genes to hemophiliacs, correcting deficiencies or defects in the clotting mechanism.
