“…40 Moreover, some new leukocyte parameters (neutrophil and monocyte volume, conductivity, scattering, and volume distribution width) may be useful in the differential diagnosis of newborn sepsis. 41 Macrophage cytokines, which are produced in response to microorganism antigens and which stimulate the release of acute-phase reactants and hence the host inflammatory immune reaction, are usually used in clinical practice as indicators of both EOS and LOS. 42 Moreover, serum markers, increasing earlier than changes in hematological parameters, play a pivotal role in the diagnostic process, allowing detection of sepsis and its severity, differentiation of bacterial from fungal and viral agents, and monitoring of response to therapy.…”
