Immune Thrombocytopenia ( Disease & Conditions, Treatments & Procedures , Symptoms )
Immune thrombocytopenia (ITP) is a blood disorder characterized by a low platelet count due to the immune system attacking and destroying platelets in the blood. Platelets are important for blood clotting and people with ITP may experience bruising, petechiae (small red dots on the skin), and in severe cases, bleeding. ITP can affect people of any age, but is most commonly diagnosed in children and young adults. In some cases, ITP may resolve on its own, while in others, treatment such as medication or surgery may be necessary to manage symptoms.

What is immune thrombocytopenia?
Immune thrombocytopenia (ITP), also known as idiopathic thrombocytopenic purpura, is a disorder in which the body’s immune system mistakenly attacks and destroys platelets, which are necessary for normal blood clotting. The condition can occur in both adults and children, and affects both sexes equally.
The exact cause of ITP is not fully understood. In some cases, it may occur after a viral infection, particularly in children. Other potential causes include certain medications, autoimmune diseases, pregnancy, and certain cancers.
Symptoms of ITP can include easy bruising, petechiae (tiny red or purple dots on the skin), bleeding from the gums or nose, blood in the urine or stools, and excessive menstrual bleeding in women. Some people with ITP may have no symptoms at all.
Diagnosis of ITP typically involves a complete blood count (CBC), which can show a low platelet count. Additional blood tests may be performed to look for antibodies that attack platelets, which can confirm the diagnosis of ITP.
Treatment of ITP depends on the severity of symptoms and platelet count. Mild cases may not require treatment, while more severe cases may require medication, such as corticosteroids or immunoglobulin therapy, to help raise the platelet count. In some cases, surgery to remove the spleen (splenectomy) may be necessary.
Most people with ITP recover fully with treatment. However, some people may experience chronic ITP, which can last for many years and may require ongoing treatment. In rare cases, ITP can lead to serious bleeding, which can be life-threatening.
If you are experiencing symptoms of ITP or have been diagnosed with the condition, it is important to work closely with your healthcare provider to determine the best course of treatment and to monitor your platelet count regularly.
What are the types of immune thrombocytopenia?
There are two types of immune thrombocytopenia (ITP): acute and chronic.
Acute ITP usually occurs in children and often follows a viral infection. It is typically self-limiting, with platelet counts returning to normal within a few weeks to months without treatment.
Chronic ITP, on the other hand, is more common in adults and is characterized by a persistently low platelet count for at least six months. It can also occur in children and adolescents, but it is less common than acute ITP. Chronic ITP can be further divided into primary and secondary forms.
Primary ITP occurs when there is no underlying cause or identifiable trigger for the low platelet count. Secondary ITP occurs in association with another underlying condition or as a result of medication use. Some of the conditions that may cause secondary ITP include autoimmune diseases, infections, lymphoproliferative disorders, and malignancies. Certain medications, such as heparin and quinine, can also induce ITP.
What is acute immune thrombocytopenia?
Acute immune thrombocytopenia, also known as acute immune thrombocytopenic purpura (ITP), is a type of ITP that develops suddenly and lasts for less than 6 months. It is more common in children and usually occurs after a viral infection. The symptoms of acute ITP may include easy bruising, petechiae (small red or purple spots on the skin), nosebleeds, and bleeding gums. Most children with acute ITP recover within a few months without treatment, although some may require medical intervention if the bleeding is severe. In rare cases, acute ITP can be life-threatening if bleeding occurs in the brain or other vital organs.
What is chronic immune thrombocytopenia?
Chronic immune thrombocytopenia (ITP) is a long-term condition that causes a low platelet count in the blood. Platelets are blood cells that help in clotting and prevent bleeding. In chronic ITP, the body’s immune system mistakenly attacks and destroys platelets in the blood, leading to a low platelet count.
Chronic ITP is more common in adults, and women are affected more often than men. The condition can occur at any age, but it usually develops in people younger than 40 years.
The exact cause of chronic ITP is unknown, but it is thought to be an autoimmune disorder. This means that the immune system mistakenly attacks healthy cells and tissues in the body, including platelets. In some cases, chronic ITP can be triggered by an infection, pregnancy, or medication.
Symptoms of chronic ITP may include bruising easily, small red or purple spots on the skin (petechiae), and bleeding from the gums or nose. In some cases, people with chronic ITP may not have any symptoms.
The diagnosis of chronic ITP is made through a physical exam, blood tests to measure platelet count and function, and a bone marrow biopsy in some cases.
Treatment options for chronic ITP may include medications that suppress the immune system, such as corticosteroids, rituximab, or thrombopoietin receptor agonists. In severe cases, a splenectomy (removal of the spleen) may be recommended. Lifestyle changes such as avoiding contact sports and taking precautions to avoid bleeding may also be helpful.
Most people with chronic ITP can live a normal life with proper treatment and monitoring. However, the condition can be chronic and may require ongoing treatment and monitoring to prevent complications such as bleeding.
What causes immune thrombocytopenia?
The exact cause of immune thrombocytopenia (ITP) is unknown, but it is believed to be an autoimmune disorder, where the body’s immune system mistakenly attacks and destroys its own platelets. This leads to a low platelet count in the blood and an increased risk of bleeding. In some cases, ITP may be triggered by a viral or bacterial infection, medications, or certain medical conditions such as lupus or HIV. It can also occur as a complication of pregnancy.
What are the symptoms of immune thrombocytopenia?
The symptoms of immune thrombocytopenia can vary depending on the severity of the condition. Some people may not have any symptoms at all, while others may experience:
*Easy or excessive bruising: This can occur even with minor injuries.
*Petechiae: These are small red or purple spots on the skin that occur due to bleeding under the skin.
*Prolonged bleeding: This can occur after minor cuts, dental work, or surgery.
*Heavy menstrual bleeding: This can occur in women.
*Blood in the urine or stools: This can occur due to bleeding in the kidneys or digestive system.
*Fatigue or weakness: This can occur due to anemia caused by bleeding.
*Enlarged spleen: In some cases, the spleen may become enlarged due to the increased destruction of platelets.
It’s important to note that not all cases of immune thrombocytopenia will cause symptoms, especially if the platelet count is only slightly decreased.
How is immune thrombocytopenia diagnosed?
The diagnosis of immune thrombocytopenia (ITP) involves a combination of medical history, physical examination, and laboratory tests. The following are some of the diagnostic tests commonly used:
1-Complete blood count (CBC): This test measures the number of platelets in the blood. In ITP, platelet counts are often low.
2-Blood smear: A blood smear is a microscope slide that contains a small drop of blood spread out in a thin layer. The blood smear allows a healthcare provider to examine the shape and size of the platelets and other blood cells.
3-Bone marrow aspiration and biopsy: This is an invasive procedure where a needle is inserted into the bone to take a small sample of bone marrow. The bone marrow sample is then examined under a microscope to see if there are any abnormalities in the production of platelets.
4-Blood tests: Blood tests may be done to check for the presence of antibodies, which can help diagnose the cause of the low platelet count.
5-Ultrasound: An ultrasound may be done to check for an enlarged spleen, which can be a cause of low platelet counts.
6-CT or MRI scans: These tests may be done to look for other causes of low platelet counts, such as a tumor or an enlarged spleen.
It is important to note that the diagnosis of ITP is often one of exclusion, meaning that other potential causes of low platelet counts must be ruled out before a diagnosis of ITP can be made.
How is immune thrombocytopenia treated?
The treatment of immune thrombocytopenia (ITP) depends on the severity of the condition, the presence of symptoms, and the patient’s age and overall health. In some cases, treatment may not be necessary if the platelet counts are not too low and there are no significant symptoms. However, in cases where the platelet counts are very low, treatment may be needed to prevent bleeding complications.
Some of the common treatment options for ITP include:
1-Corticosteroids: These medications, such as prednisone, are often used as the first-line treatment for ITP. They work by suppressing the immune system, which can help increase the platelet count. However, long-term use of corticosteroids can have side effects.
2-Intravenous immunoglobulin (IVIG): This treatment involves the infusion of immunoglobulin (a protein that helps fight infection) into the bloodstream. IVIG can help increase the platelet count by blocking the antibodies that destroy platelets.
3-Splenectomy: In cases where other treatments have failed or if the patient is experiencing severe bleeding, removal of the spleen may be recommended. The spleen is the organ responsible for destroying platelets, so removing it can help increase the platelet count. However, this procedure carries some risks, and patients who undergo splenectomy are at increased risk of developing infections.
4-Immunosuppressive drugs: These medications, such as azathioprine or cyclosporine, work by suppressing the immune system and can be used in cases where other treatments have failed.
5-Thrombopoietin receptor agonists: These medications, such as romiplostim or eltrombopag, work by stimulating the bone marrow to produce more platelets.
6-Platelet transfusions: Platelet transfusions may be used in cases where the platelet count is very low and the patient is experiencing bleeding. However, platelet transfusions are not a long-term solution and can carry some risks.
It’s important to note that the treatment of ITP is individualized and may involve a combination of these treatments. Patients with ITP should work closely with their healthcare providers to determine the best treatment plan for their individual needs.
What are the other ways to treat immune thrombocytopenia?
In addition to the main treatment options mentioned earlier, there are other ways to treat immune thrombocytopenia (ITP). These may include:
1-Intravenous immunoglobulin (IVIG): This treatment involves giving high doses of immunoglobulins (proteins that help fight infections) through a vein. IVIG can help increase platelet counts by blocking antibodies that destroy them.
2-Splenectomy: If other treatments fail, a splenectomy may be recommended. This surgery involves removing the spleen, which is a major site for the destruction of platelets in people with ITP. Without the spleen, platelet counts may increase, but there is an increased risk of infections.
3-Immunosuppressive drugs: These drugs can help reduce the activity of the immune system, which can help reduce the destruction of platelets. Examples of immunosuppressive drugs used for ITP include azathioprine, mycophenolate mofetil, and cyclosporine.
4-Thrombopoietin receptor agonists: These drugs help increase the production of platelets by stimulating the bone marrow to produce more of them. Examples of thrombopoietin receptor agonists used for ITP include eltrombopag and romiplostim.
5-Rituximab: This drug is a monoclonal antibody that targets and destroys B cells, which are responsible for producing the antibodies that attack platelets in ITP.
It is important to note that the choice of treatment will depend on the severity of the ITP, the age and health status of the patient, and other factors, and that treatment options may change over time based on the response to treatment.
How can I reduce my risk of immune thrombocytopenia?
It is not possible to prevent immune thrombocytopenia since the exact cause is not known. However, there are some general measures that individuals with the condition can take to reduce their risk of bleeding or bruising, such as:
1-Avoiding activities or situations that can lead to injury or bleeding.
2-Being cautious when taking medications, especially those that can affect blood clotting or platelet function. Always inform your healthcare provider about all medications and supplements you are taking.
3-Maintaining a healthy lifestyle, including a balanced diet and regular exercise.
4-Managing any underlying medical conditions that may increase the risk of immune thrombocytopenia, such as autoimmune disorders or infections.
5-Seeking prompt medical attention if you experience symptoms of bleeding or bruising, such as excessive bruising, nosebleeds, or prolonged bleeding from cuts.
What can I expect if I have immune thrombocytopenia?
If you have immune thrombocytopenia, the outlook varies depending on the type and severity of the condition. Acute immune thrombocytopenia often resolves on its own within a few weeks to months, while chronic immune thrombocytopenia can persist for years or even a lifetime.
Treatment can be effective in increasing the platelet count and reducing the risk of bleeding. However, some treatments may have side effects, and not all individuals respond to treatment. In some cases, a splenectomy (removal of the spleen) may be recommended as a treatment option.
It’s important to work closely with your healthcare provider to develop an individualized treatment plan and to monitor your condition over time. With proper management and follow-up, many people with immune thrombocytopenia are able to lead healthy and active lives.
How long will you have immune thrombocytopenia?
The duration of immune thrombocytopenia can vary depending on the type and the individual case. Acute immune thrombocytopenia usually resolves on its own within a few weeks to a few months. Chronic immune thrombocytopenia can last for many years and may require ongoing treatment. Some people with chronic immune thrombocytopenia may experience periods of remission where they have normal platelet counts, while others may have ongoing symptoms. It is important to work with a healthcare provider to monitor the condition and manage symptoms.
How do I take care of myself with immune thrombocytopenia?
If you have immune thrombocytopenia, there are several things you can do to take care of yourself:
1-Follow your doctor’s instructions: Make sure you follow the treatment plan that your doctor has prescribed for you. Take your medications as directed, and keep your appointments with your doctor.
2-Watch for signs of bleeding: If you notice any unusual bleeding or bruising, contact your doctor right away. This includes nosebleeds, bleeding gums, heavy menstrual bleeding, blood in your urine or stool, or any other unusual bleeding.
3-Avoid activities that may cause injury: Avoid activities that may result in injury, such as contact sports or heavy lifting. Talk to your doctor before starting any new exercise routine or activity.
4-Eat a healthy diet: Eating a balanced diet can help ensure that your body is getting the nutrients it needs to stay healthy.
5-Manage stress: Stress can weaken your immune system and make it harder for your body to fight infections. Find ways to manage your stress, such as through exercise, meditation, or talking to a counselor.
6-Stay up to date on vaccinations: Vaccinations can help prevent infections that may trigger immune thrombocytopenia. Make sure you stay up to date on all recommended vaccinations.
7-Carry a medical alert card: Consider carrying a medical alert card or bracelet that lets others know you have immune thrombocytopenia in case of an emergency.
Remember to talk to your doctor about any questions or concerns you may have about taking care of yourself with immune thrombocytopenia.
What if I have immune thrombocytopenia while I’m pregnant?
If you have immune thrombocytopenia (ITP) during pregnancy, it is important to talk to your healthcare provider. In general, if you have mild or asymptomatic ITP, your healthcare provider may monitor your platelet levels regularly but may not recommend treatment. However, if your platelet counts are very low or you are experiencing bleeding symptoms, your healthcare provider may recommend treatment to increase your platelet counts and reduce the risk of bleeding.
The treatment options for ITP during pregnancy depend on several factors, such as the severity of the disease, the stage of pregnancy, and the risk of bleeding. Some treatment options that may be considered include corticosteroids, intravenous immunoglobulin (IVIG), and platelet transfusions.
It is important to note that some treatments for ITP may pose risks to the developing fetus, so your healthcare provider will carefully consider the risks and benefits of any treatment options before making a recommendation.
Additionally, it is important to have a plan in place for labor and delivery if you have ITP. Your healthcare provider may recommend additional monitoring or interventions during labor and delivery to reduce the risk of bleeding.
