However, no data has been obtained indicating that, in patients with community-acquired pneumonia hospitalized in the ICU, NET level in smears made from venous blood is associated with the presence of inotropic support, risk factors for an unfavorable outcome, the development of complications, the outcome of the disease, the level of leukocytes and CRP, as well as with the type of a clinically significant causative agent of pneumonia, although according to the literature, we have found studies that demonstrate the presence of this relationship [22–26]. The gene discussed is CRP; the disease is susceptibility to pneumonia measurement.
