How Is Idiopathic Thrombocytopenic Purpura
Treated?
Treatment for idiopathic thrombocytopenic purpura
(ITP) is based on how much and how often youre bleeding and your platelet
count. In some cases, treatment may not be needed.
Medicines often are used as the first course of
treatment. Treatments used for children and adults are similar.
Adults with ITP who have very low platelet counts or
problems with bleeding often are treated. Adults who have milder cases of ITP
may not need any treatment, other than watching their symptoms and platelet
counts.
The acute (short-term) type of ITP that occurs in
children often goes away within a few weeks or months. Children who have
bleeding symptoms, other than merely bruising (purpura), usually are
treated.
Children who have milder cases of ITP may not need
treatment other than monitoring and followup to make sure platelet counts
return to normal.
Medicines
If adults or children who have ITP need treatment,
medicines often are tried first. Corticosteroids (cor-ti-co-STEER-roids), such
as prednisone, are commonly used to treat ITP.
These medicines, called steroids for short, help
increase your platelet count by lowering the activity of your immune system.
However, steroids have a number of side effects, and some people relapse (get
worse) when treatment ends.
The steroids used to treat ITP are different from
illegal steroids taken by some athletes to enhance performance. Corticosteroids
aren't habit-forming, even if you take them for many years.
Some medicines used to help raise the platelet count
are given through a needle inserted into a vein. These medicines include immune
globulin and anti-Rh (D) immunoglobulin.
Medicines also may be used along with a procedure to
remove the spleen, called splenectomy (splee-NECK-tuh-mee).
If steroids, immunoglobulins, or splenectomy
dont help, two newer medicineseltrombopag and romiplostimcan
be used to treat ITP.
Removal of the Spleen (Splenectomy)
If necessary, the spleen will be removed surgically.
This organ is located in the upper left abdomen. The spleen is about the size
of a golf ball in children and a baseball in adults.
The spleen makes antibodies (proteins) that help
fight infection. In ITP, these antibodies destroy platelets.
If ITP hasn't responded to steroids, removing the
spleen will reduce the destruction of platelets. However, it also may make you
more likely to get certain infections. Before you have the surgery, your doctor
may give you vaccines to help prevent these infections.
If your spleen is removed, your doctor will explain
what steps you can take to help avoid infections and what symptoms to watch
for.
Other Treatments
Platelet Transfusions
Some people with ITP who have severe bleeding may
need to have platelet transfusions and be hospitalized. Some people will need a
platelet transfusion before having surgery.
For a platelet transfusion, donor platelets from a
blood bank are injected into the recipient's bloodstream. This increases the
platelet count for a short time.
For more information on platelet transfusions, see
the Diseases and Conditions Index
Blood
Transfusion article.
Treating Infections
Some infections can briefly lower a person's
platelet count. If a person who has ITP has an infection that can lower his or
her platelet count, treating the infection may help increase the platelet count
and reduce bleeding problems.
Stopping Medicines
If a person who has ITP is taking medicine that can
lower his or her platelet count or cause bleeding, stopping the medicine can
sometimes help increase the platelet count or prevent bleeding.
For example, aspirin and ibuprofen are common
medicines that increase the chance of bleeding. If you have ITP, your doctor
may suggest that you avoid these medicines.
