Infection with SARS-CoV-2, the cause of coronavirus infectious disease-19 (COVID-19), has caused a pandemic. Few data are available about the risk of
COVID-19 infection in persons with hematological
cancer, but controversy whether these persons have the same clinical signs and outcomes. We describe a case of life-threatening
COVID-19 infection complicated by severe
anemia in patients affected also by
chronic myelogenous leukemia. The screening for RBC
antibodies and the direct antiglobulin test (DAT) turned positive. The identification of the
antibodies, showed the presence of an alloantibody with anti-Lewis b specificity, which was reactive at room temperature, in the anti-human
globulin phase (AGH) and with
papain-treated red blood cells. At the same time
hemophagocytic lymphohistiocytosis (HLH), on the basis of major laboratory findings including hyperferritnemia, increase of triglicerides levels and according to the HLH score was suspected. Patients received
antiviral therapy,
steroids and
intravenous immunoglobulins.
Hemolysis resolved and
ferritin dramatically decreased after administration of Ig and a Afull recovery was achieved after
viral infection resolution.This case highlights the novel and multifaceted hematological findings during sever
COVID 19 infection. COVID 19-related
pneumonia is mediated by hyper activation of effector T cells and excessive production of inflammatory
cytokines, such as
IL-6,
IL-1,
interferon-gamma, and TNF. This inflammatory process called "
cytokine storm" is a life-threatening complication of
COVID 19 infection. In this case severe immunohematological consequences are reported for the first time and recognition of this complications are probably underestimated.
