Overview

Recent pandemic of COVID-19 infection is shown to have multi-systemic complication. Hematologic complication of COVID-19 include Lymphopenia, Neutrophilia, Thrombocytopenia. some articles suggest that Hemoglobin may decrease in the event of disease.

Complications

Lymphopenia

There is an assosiation between sever COVID-19 infection and lymphopenia.[1]

Neutrophilia

Thrombocytopenia

There is an association between severe COVID-19 infection and thrombocytopenia.[2] Thrombocytopenia is seen in 57.7% of patients with severe COVID-19 infection compared to 31.6 % of patients with non-severe infection.[3]

The pathogenesis of thrombocytopenia in COVID-19 infection is due to several factors:[4]

  • Decrease in primary platelet production due to infection of bone marrow cells by coronaviruses[5] and inhibition of bone marrow growth,[6] which lead to abnormal hematopoietic function.[4]
  • Increase in platelet destruction due to increase in auto-antibodies and immune complexes.[7]
  • Decrease in circulating platelet due to lung injury which causes megakaryocyte fragmentation and decreases platelet production, because lung is a reservoir for megakaryocyte and hematopoieitic progenitor cells and has a role in platelet production.[4][8] In addition, decrease in platelets may be due to activation of platelets that result in platelet aggregation and formation of microthrombus which increase platelet consumption.[4][9]

Hemoglobin decrease
