Idiopathic Thrombocytopenic Purpura overview and Definition
Idiopathic thrombocytopenic purpura is an immune disorder in which the blood doesn’t clot normally. This condition is now more commonly referred to as immune thrombocytopenia ( ITP) .
It can cause excessive bruising and bleeding. An usually low level of platelets or thrombocytes in the blood results in ITP. Platelets are produced in the bone marrow, they have stop bleeding by clumping together to form a clot that seals cuts or small tears in blood vessel walls and tissues. If the blood doesn’t have enough platelets, it’s slow to clot.
Internal bleeding or bleeding on or under the skin can result. People with Idiopathic thrombocytopenic purpura often have many purple bruises called purpura on the skin or mucous membrane inside the mouth. These bruises may also appear as pinpoint sized red or purple dots on the skin called as petechiae. It often look loke a rash.
Idiopathic thrombocytopenic purpura can occur in both children and adults. There appears to be differences at certain ages between women and men and the development of ITP. At younger ages, ITP may be more common in women. At older ages, it may be more common in men. Children are most likely to develop this condition after a general viral illness. Some specific viruses, such as chickenpox, mumps, and measles, have been linked to ITP as well.
