Morphological and functional features of peripheral blood neutrophils in cancer patients with sepsis in the early postoperative period (review of literature and results of our own studies)

The study was performed in 9 cancer patients with sepsis. A clinical blood test of patients with sepsis was accompanied by a neutrophilic leukemoid reaction, with the appearance in the differential count of white blood cells of young cells (myelocytes, metamyelocytes). According to the literature, it is shown that in severe sepsis, a local infection is accompanied by systemic of neutrophil activation (NF). Moreover, excessive activation and location of NF in the microvasculature, especially its young forms and the formation of extracellular trap networks (NETs), can contribute to pathological manifestations of multiple organ failure and thrombosis.

Immune Pathogenesis of COVID-19 Intoxication: Storm or Silence?

Dysregulation of the immune system undoubtedly plays an important and, perhaps, determining role in the COVID-19 pathogenesis. While the main treatment of the COVID-19 intoxication is focused on neutralizing the excessive inflammatory response, it is worth considering an equally significant problem of the immunosuppressive conditions including immuno-paralysis, which lead to the secondary infection. Therefore, choosing a treatment strategy for the immune-mediated complications of coronavirus infection, one has to pass between Scylla and Charybdis, so that, in the fight against the "cytokine storm," it is vital not to miss the point of the immune silence that turns into immuno-paralysis.
