What Is Immune Thrombocytopenia (ITP)? Symptoms, Causes, Diagnosis, Treatment, and Prevention
Individuals with ITP are therefore susceptible to excessive bleeding and bruising.
7 Signs and Symptoms of ITP
Signs and Symptoms of ITP
Symptoms may begin to appear when platelet levels are very low. According to the National Organization for Rare Disorders (NORD), symptoms of ITP can include:
- Bruising or purple spots on the skin that occur very easily or for no known reason
- Small red dots that resemble a rash
- Frequent nosebleeds
- Bleeding from the gums
- Unusually long or heavy menstrual bleeding
- Hematoma, or a pooling of clotted or partially clotted blood under the skin. A hematoma can cause pain and swelling.
- Blood in urine, stool, or vomit
Causes and Risk Factors of ITP
Women are more likely to get ITP than men.
How Is ITP Diagnosed?
Certain blood tests can check your platelet count. According to the Cleveland Clinic, these include:
- A complete blood count, which checks your number of white blood cells, red blood cells, and platelets
- A blood smear, in which your blood is put on a slide and a doctor checks your platelet levels
In rare cases, a bone marrow test may also be performed to check if your bone marrow is making enough platelets. Your doctor may also screen you for HIV, hepatitis C, or H. pylori. They may also order an anti-platelet antibody test, yet the accuracy of these tests varies.

Treatment and Medication Options for ITP
There is no cure for ITP, but there are effective ways to manage it. One of these strategies is to use medication. These may include:
- Treatment with an oral corticosteroid, such as prednisone, dexamethasone, or methylprednisolone, is usually the first line of treatment for ITP, according to the National Organization for Rare Diseases (NORD).These drugs can get your platelets back to safe levels but are only recommended for short-term use, as they can increase your risk of a number of health conditions, including high blood pressure, infections, and osteoporosis, according to the Mayo Clinic.
- Immune Globulin If your body doesn’t respond to corticosteroids, your doctor may recommend immune globulin. According to NORD, this medication is administered through an IV on an as-needed basis, usually two to four weeks.Immune globulin can be used in an emergency if you have critical bleeding or need to up your platelet levels right away, according to the Mayo Clinic.
- Drugs to Raise Platelet Count Certain medication can boost platelet production, including Nplate (romiplostim), Promacta (eltrombopag), and Rituxan and Truxima (rituximab), according to the Mayo Clinic.
In severe cases of ITP or when there is little response to medication therapy, surgery to remove the spleen may be needed. This procedure is called a splenectomy.
The spleen is an organ responsible for making antibodies that fight infections. When an individual has ITP, these antibodies attack platelets by mistake. Removing the spleen may help get platelets back to a normal level, although effectiveness is variable and estimated to be 50 to 70 percent compared with nonsurgical treatment.
Prevention of ITP
These include avoiding medicines that can increase the risk of bleeding, such as ibuprofen and aspirin. Always talk to your doctor before starting any new medication or supplement.
Avoid contact sports that can lead to head injuries, such as boxing, football, and karate. Generally, swimming, cycling with a helmet, and walking are considered safe forms of physical activity.
If you have any signs of an infection, especially a fever, call your doctor right away. Getting prompt treatment can help prevent complications.
Complications of ITP
Research and Statistics: How Many People Have ITP?
In children, the prevalence of ITP is approximately 5.3 per 100,000. Across the globe it’s estimated that more than 200,000 people are living with ITP.
Related Conditions and Causes of ITP
ITP is linked to a number of infections, including HIV, hepatitis C, and H. pylori.
