Understanding Immune Thrombocytopenia: Causes, Symptoms, and Treatment

Introduction

Immune thrombocytopenia (ITP), also known as idiopathic thrombocytopenic purpura, is a condition in which the immune system mistakenly attacks and destroys platelets, the cells responsible for blood clotting. This can lead to excessive bleeding and bruising.

Causes

The exact cause of ITP is unknown, but it is thought to be an autoimmune disorder in which the body produces antibodies that bind to platelets. These antibodies can cause the platelets to be destroyed by the spleen or other parts of the immune system.

ITP can be acute or chronic. Acute ITP typically develops suddenly and lasts for less than 6 months. It is most common in children and usually resolves on its own.

Chronic ITP lasts for more than 6 months and is more common in adults. It can be a lifelong condition, but it can be managed with treatment.

Symptoms

The main symptom of ITP is excessive bleeding and bruising. This can occur anywhere on the body, but it is most common in the skin, mouth, and nose.

Other symptoms of ITP include:

• Fatigue
• Weakness
• Shortness of breath
• Dizziness
• Headaches
• Abdominal pain
• Nausea and vomiting

Diagnosis

ITP is diagnosed with a blood test that measures the platelet count. A normal platelet count is between 150,000 and 450,000 platelets per microliter of blood. A platelet count below 150,000 platelets per microliter of blood is considered thrombocytopenia.

Your doctor may also order other tests to rule out other causes of thrombocytopenia, such as leukemia or lymphoma.

Treatment

The treatment for ITP depends on the severity of the condition. For mild cases, no treatment may be necessary. For more severe cases, treatment may include:

• Medications to suppress the immune system, such as corticosteroids, intravenous immunoglobulin (IVIG), and rituximab
• Platelet transfusions to increase the platelet count
• Surgery to remove the spleen, which is the organ that destroys platelets

Prognosis

The prognosis for ITP varies. Acute ITP usually resolves on its own within a few months. Chronic ITP can be a lifelong condition, but it can be managed with treatment.

The outlook for people with ITP is generally good. Most people with ITP are able to live full and active lives.
