Pronunciation
  • THROM-bo-si-to-PE-ne-ah[1]
SpecialtyHematology
SymptomsPurple bruises, small red dots in the skin, bleeding gums[1]
CausesBone marrow not making enough, increased destruction, spleen holding too many[1]
Diagnostic methodPlatelets < 150 x 109/L[2]
TreatmentNone, immunosuppressants, platelet transfusion, surgical removal of the spleen[1]
FrequencyRelatively common[3]

Thrombocytopenia is a low levels of platelets (thrombocytes) in the blood.[1] Symptoms may include bleeding, including within the body, into the skin, or externally such as from the gums.[1] Bleeding into the skin may result in purpura (purple bruises) or petechiae (small red dots).[1]

Low platelets may occur due to insufficient production, increased destruction, or the spleen holding on to too many.[1] Insufficient production may occur due to leukemia, aplastic anemia, certain chemicals or medications, alcohol, viral infections, and genetic conditions.[1] Increased destruction may occur due to immune thrombocytopenia (ITP), certain medications, infections, surgery, pregnancy, thrombotic thrombocytopenic purpura (TTP) and disseminated intravascular coagulation (DIC).[1] The spleen may hold on to too many when it is enlarged.[1] In adults there are normally 150 to 450 x 109 platelets per L (150,000 to 450,000 per mm3) of blood with values below that defined as thrombocytopenia.[2]

Treatment depends on the cause.[1] Mild cases may not require specific treatment.[1] In severe disease corticosteroids, rituximab, or eltrombopag may be used.[1] When platelets are below 20 x 109 per L a platelet transfusion may be recommended.[2] Surgical removal of the spleen may be used if medications are not effective.[1] The condition is relatively common, with about half of people in the intensive care unit having the condition.[3]
