Justification. Knowledge of the differences in response to therapy between phenotypes of exacerbations of chronic obstructive pulmonary disease (COPD) is necessary to improve treatment outcomes. Objective: to determine the most effective additional pharmacological methods for virus-associated exacerbations of COPD. Material and methods. The study included patients hospitalized with exacerbations of COPD with viral (n = 60) and viral-bacterial (n = 60) infections, and a comparison group with exacerbations of COPD with bacterial infection (n = 60). The diagnosis of COPD was based on spirometric criteria, viral infection — according to the results of PCR-RV of sputum for RNA of respiratory viruses. Treatment was carried out in real clinical practice. The groups were comparable in the use of systemic glucocorticoids, short-acting bronchodilators. Dyspnea was assessed using the TDI index (primary endpoint), lung function (spirometry, diffusion capacity for carbon monoxide), exercise tolerance (6-minute walk test), length of hospital stay (secondary endpoints). The сorrelations were determined with the use of Cox proportional hazards model. Results. In the groups with virus-associated and viral-bacterial exacerbations, unlike bacterial exacerbations, the following types of treatment were associated with achieving TDI +1 (odds ratio — OR, 95 % confidence interval — CI): fixed triple combination (OR 2.69; 95 % CI 1.48–4.90; p = 0.010 and OR 2.74; 95 % CI 1.29–3.80; p = 0.031), inhalation of 3 % sodium chloride solution (OR 3.64; 95 % CI 1.45–5.42; p = 0.001 and OR 3.23; 95 % CI 2.15–5.43;\ p = 0.042), antiviral drugs (OR 2.91; 95 % CI 1.15–3.62; p = 0.009 and OR 2.76; 95 % CI 1.31–3.90; p = 0.008). As a result of treatment, an increase in DLco/Va, SpO2 after a 6-minute walk, and a decrease in the length of hospital stay were observed. Conclusion. Detection of virus-associated infections is a promising marker for determining indications for prescribing long-acting anticholinergic drugs and beta-adrenomimetics, inhaled corticosteroids, inhalations of hypertonic sodium chloride solution, and antiviral drugs for exacerbations of COPD.
