What are the symptoms of heparin induced thrombocytopenia?

What are the signs and symptoms of HIT?

  • Pain, redness, and swelling of an arm or leg.
  • Bruise-like discoloration of your skin.
  • A rash or sore where a heparin shot was given.
  • Weakness, numbness, or problems moving your arms or legs.

Consequently, what is heparin induced thrombocytopenia?

Heparininduced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT is caused by the formation of abnormal antibodies that activate platelets.

Similarly, what is heparin induced thrombocytopenia and how is it treated? Patients with HIT are at high risk for thrombotic events and should be treated with alternative anticoagulants, typically a direct thrombin inhibitor (DTI). The US Food and Drug Administration (FDA) has approved the DTI argatroban (Acova) for prophylaxis and treatment of thrombosis in patients with HIT.

Likewise, does heparin induced thrombocytopenia go away?

Pathology of HIT: UFH antibody does not crossreact with LMWH antibody. All patients who develop HIT antibodies will subsequently develop clinical syndrome of HIT. HIT antibodies begin to disappear in 4–10 days after cessation of heparin treatment.

How common is heparin induced thrombocytopenia?

A study by Smythe and colleagues estimated the frequency of heparininduced thrombocytopenia (HIT) to be 0.76% in patients receiving therapeutic doses of intravenous unfractionated heparin (UFH) and less than 0.1% in patients receiving antithrombotic prophylaxis with subcutaneous UFH, with an overall risk of HIT of
