What is the prevalence of Idiopathic Thrombocytopenic Purpura?

How many people does Idiopathic Thrombocytopenic Purpura affect? Does it have the same prevalence in men and women? And in the different countries?


Idiopathic Thrombocytopenic Purpura (ITP) is a rare autoimmune disorder characterized by a low platelet count, leading to excessive bleeding and bruising. The prevalence of ITP varies across different populations and age groups.


According to available data, the estimated prevalence of ITP is around 9.5 to 10.8 cases per 100,000 adults and 5.3 to 6.4 cases per 100,000 children. However, it is important to note that these figures may not capture the full extent of the condition, as milder cases may go undiagnosed or unreported.


ITP can affect individuals of any age, but it is more commonly diagnosed in children and young adults. The exact cause of ITP is unknown, hence the term "idiopathic." It is believed to involve the immune system mistakenly attacking and destroying platelets, leading to their reduced numbers.


While ITP is considered a rare disorder, it can have a significant impact on the quality of life for those affected. Prompt diagnosis and appropriate management are crucial in minimizing complications and ensuring the well-being of individuals living with ITP.

The incidence was higher among women [4.5 per 100 000 PYs (95% CI: 4.2, 4.9)] than men [3.2 per 100 000 PYs (95% CI: 2.8, 3.5)]. Among both women and men, incidence was higher at older ages and in later study years. In a systematic review of previously published literature, incidence of ITP among adults ranged from 1.6 to 2.68 per 100 000 persons per year; prevalence ranged from 9.5 to 23.6 per 100 000 persons. In order to improve the understanding of the disease burden of ITP, future studies should include a clearly defined definition of ITP and focus on well-described source populations that are geographically and ethnically diverse.
