Idiopathic Thrombocytopenic Purpura
Clinical Features
• Onset of chronic ITP is insidious• Characterized by:
– mucocutaneous bleeding and a low, often very low, platelet count, with otherwise normal peripheral blood cells and smear
• Rarely, life-threatening bleeding, including in the central nervous system, (intracerebral or subarachnoid hemorrhages) can occur (<5,000 per mm3)
• The amount and severity of symptoms is related to the severity of the decrease in the platelet count Harrison’s Principle of Internal Medicine 17th ed.

Two types of ITP
• Acute (temporary or short-term) ITP:– generally lasts less than 6 months– mainly occurs in children, both boys and girls, and is
the most common type of ITP– often occurs after an infection caused by a virus
• Chronic (long-lasting) ITP: – lasts 6 months or longer and mostly affects adults– some teenagers and children can get this type of ITP– affects women 2 to 3 times more often than men

• Any kind of bleeding that is hard to stop could be a sign of ITP
• A low number of platelets doesn't cause pain, fatigue (tiredness), problems concentrating, or any other symptoms
