Idiopathic Thrombocytopenic Purpura
Question: My son developed a disorder called ITP-whose symptoms mimic those of leukemia- Bruises appeared all over his limbs and his platelet count dropped very low. What is the cause of ITP and is there anything that can prevent it from recurring?
Answer: ITP, also known as Idiopathic Thrombocytopenic Purpura (a very scary and long
name for a platelet disorder). Platelets are cells in the body that help to
Technically, the definition of Idiopathic is "WE DON'T KNOW THE CAUSE." Viruses are thought to cause the majority of cases. Some cases are caused by the
body actually destroying it's own platelets. The spleen is the organ
responsible for platelet destruction. In severe cases, removal of the spleen
may be necessary.
Bruising from low platelets occurs because of bleeding under the skin. This
results in the bruising that you described on your son. Treatment is aimed
at restoring the number of platelets, usually by special medications. If
platelets remain low for months or years, it is said to be chronic.
Because most cases of ITP occur without a cause, it is difficult to prevent.
Luckily, the majority resolve without major problems.
