Thrombocytopenia

There is an association between severe COVID-19 infection and thrombocytopenia. (lippi) Thrombocytopenia is seen in 57.7% of patients with severe COVID-19 infection compared to 31.6 % of patients with non-severe infection. (GUAN)

The pathogenesis of thrombocytopenia in COVID-19 infection is due to several factors: (XU et al)

  1.    Decrease in primary platelet production due to:
    • Infection of bone marrow cells by coronaviruses(12-yang) and inhibition  of bone marrow growth, (14 yeager) which lead to abnormal  hematopoietic function
    • Cytokine storm caused by COVID-19 infection results in the destruction of bone marrow progenitor cells (XU)
  2.    Increase in platelet destruction due to increase in autoantibodies and immune complexes (18-nardi/XU)
  3.    Decrease in circulating platelet due to lung injury which causes
    • Activation of platelets that result in platelet aggregation and formation of microthrombus  which lead to increase in platelet consumption XU)
    • Decrease in pulmonary capillary bed and megakaryocyte fragmentation result in decrease in platelet production(17lefransias, XU)

Decrease in hemoglobulin

Other hematological findings
