Overview

Idiopathic Thrombocytopenic Purpura (ITP) is an autoimmune blood disorder characterized by a low platelet count. Platelets are essential for normal blood clotting. In ITP, the immune system mistakenly attacks and destroys platelets. This reduces the blood’s ability to clot properly. The condition may occur suddenly or develop gradually. It can affect both children and adults. Symptoms vary depending on platelet levels. Some individuals may experience mild bruising, while others may have more significant bleeding. ITP may be acute or chronic. Early evaluation is important to prevent complications.

In ITP, antibodies target platelets and mark them for destruction. The spleen removes these antibody-coated platelets from circulation. As platelet levels decrease, the blood’s clotting ability becomes impaired. This increases the risk of bruising, bleeding gums, or nosebleeds. In severe cases, internal bleeding may occur.

Diagnosis

Diagnosis is based on blood tests showing low platelet count. A complete blood count (CBC) confirms thrombocytopenia. Other causes of low platelets are ruled out. In some cases, bone marrow examination may be performed to assess platelet production.
