What is immune thrombocytopenic purpura?

Immune thrombocytopenic purpura (ITP) is characterized by a decrease in platelets in the blood which are cells in the blood that help in clotting. ITP can cause easy bruising and bleeding. It occurs when the immune system mistakenly attacks and destroys platelets. Triggers include infections like HIV, hepatitis, etc.

Questions your doctor may ask to check for immune thrombocytopenic purpura

Your doctor may ask these questions to diagnose immune thrombocytopenic purpura

  • Do you bleed easily, even due to minor injuries?

  • Is there blood in your stool?

  • Have you ever had red or brown urine (hematuria)?

  • Do you have bleeding in your nose or gums?

  • Do you have small red dots which look like bleeding under the skin?

Treatment for immune thrombocytopenic purpura

Children with ITP usually recover without treatment. Adults need treatment with medication to suppress the immune cells, increase platelet production/ prevent bleeding and blood transfusion. Rarely the spleen may need to be removed. In ITP, the immune system treats platelets as foreign and destroys them. Spleen removes these damaged platelets, hence spleen removal helps keep more platelets circulating in the body.
