METHOD OF ASSESSING NEED FOR ANTIBACTERIAL THERAPY IN EVENT OF BACTERIAL INFECTION IN PATIENT WITH VIRAL PNEUMONIA Russian patent published in 2023 - IPC G01N33/49 

FIELD: medicine; pulmonology; therapy.

SUBSTANCE: invention can be used to assess the need for antibacterial therapy when a bacterial infection occurs in a patient with viral pneumonia. Scores are calculated based on the results of clinical blood test parameters. The following parameters of a clinical blood test are determined: leukocytes, neutrophils, lymphocytes, platelets, monocyte to lymphocyte ratio index in patients with viral pneumonia, as well as in cases where the diagnosis of pneumonia is confirmed, but a full etiological diagnosis is not possible. If the leukocyte value is more than 7.0×10⁹/l 1 point is assigned, with a neutrophil value of more than 4.5×10⁹/l 1 point is assigned, with a lymphocyte value of more than 1.7×10⁹/l 1 point is assigned, if the platelet value is more than 208×10⁹/l 1 point is assigned, if the index value of the ratio of monocytes to lymphocytes is less than 0.21 units 1 point assigned. If the total points are 0–1, there are no indications for prescribing antibacterial therapy. If the total points are 2–3, antibiotic therapy is indicated if the body temperature remains above 37.0°C for three days. If the total points are 4–5, antibiotic therapy is indicated.

EFFECT: method provides the possibility of timely prescription of antibacterial therapy in the event of a bacterial infection in a patient with viral pneumonia in the absence of the possibility of a full bacterial etiological diagnosis by determining the following parameters of a clinical blood test: leukocytes, neutrophils, lymphocytes, platelets and the monocyte to lymphocyte ratio index, with subsequent evaluation of the results according to declared scale.
