To identify predictors of the severe course of a new coronavirus infection. ⋯ Thus, in this study, the level of CRP, ferritin, D-dimer, the percentage of lung tissue damage according to computed tomography results, SaO2 were significantly associated with an unfavorable prognosis.

The role of cyclooxygenases (COX-1 and/or COX-2), transcription nuclear factor NF-κB, anti-inflammatory cytokines - TGF1b, IL-4, IL-10 and pro-inflammatory cytokines IL-1, IL-6 were studied to substantiate the expediency of antiviral agent enisamium iodide (Nobazit) using to regulate key inflammatory components in acute respiratory infections, IL-8, TNF-alpha in the realization of the pharmacological activity of this drug. ⋯ The anti-inflammatory effect of enisamium iodide at a concentration of 10 μM may be associated with inhibition of the expression of COX-1, 2, NF-κB, IL-1, IL-6, TGF1b and an increase in the expression and production of IL-10. An additional contribution to the anti-inflammatory activity of enisamium iodide is made by its antioxidant and antiradical activity. The absence of the effect of enisamium iodide (10-100 µM) on the viability of PBMC indicates its safety for the cells of the immune system and the expediency of using it to suppress inflammatory reactions in acute respiratory infections, restore the quality of life of patients and the possibility of using Nobazit as an effective agent for treatment of these infections of various etiologies.

Community-acquired pneumonia (САР) and chronic obstructive pulmonary disease (COPD) are among the main causes of mortality worldwide, and, in addition, they also lead to great economic losses for the health system of all countries. Currently, there is an increase in cases of recurrent pneumonia, both in the general population and, in particular, in patients with COPD. One of the most important risk factors for the development of pneumonia is the previous episode of САР. Potential risk factors for recurrent pneumonia are concomitant diseases such as heart failure, COPD, diabetes mellitus, neurological disorders, swallowing dysfunction, immune deficiency. ⋯ A retrospective analysis showed that, firstly, CAP is a fairly frequent complication of COPD: initially, the average percentage of cases of САР was 19.3%. Secondly, the risk of developing repeated episodes of pneumonia remains quite high in unvaccinated patients and tends to increase within 5 years: from 17 to 22%. Thirdly, the pneumococcal vaccines used have different effects on the risk of recurrent pneumonia in patients with COPD, a significant decrease in the number of recurrent pneumonia is observed only with the use of conjugated vaccines.
