Thrombocytopenia

There is an association between severe COVID-19 infection and thrombocytopenia.[1] Thrombocytopenia is seen in 57.7% of patients with severe COVID-19 infection compared to 31.6 % of patients with non-severe infection.[2]

The pathogenesis of thrombocytopenia in COVID-19 infection is due to several factors:[3]

  1. Decrease in primary platelet production due to infection of bone marrow cells by coronaviruses[4] and inhibition of bone marrow growth,[5] which lead to abnormal hematopoietic function.[3]
  2. Increase in platelet destruction due to increase in autoantibodies and immune complexes.[6]
  3. Decrease in circulating platelet due to lung injury which causes megakaryocyte fragmentation and decreases platelet production which is because of lung's role in platelet biogenesis and reservoir for hematopoieitic progenitor cells.[3][7] In addition decrease in platelets may be due to activation of platelets that result in platelet aggregation and formation of microthrombus which lead to increase in platelet consumption.[3][8]
