The effectiveness of a polyvalent antigenic complex including bacterial lysates in the treatment and prevention of rhinosinusitis against the background of acute respiratory viral infections and COVID-19 (clinical description)

Abstract

One of the urgent tasks of the Ministry of Health of the Russian Federation, noted in the State report on the state of sanitary and epidemiological welfare of the population, is the improvement and implementation of diagnostic and treatment and prevention technologies. First of all, this concerns the continued growth of respiratory viral infections, seasonal influenza epidemics, where SARS-CoV-2 coronavirus infection occupies a special place, which often cause various otorhinolaryngological complications – acute and exacerbations of chronic tonsillopharyngitis, rhinosinusitis, tubotitis, purulent otitis media. In the treatment of bacterial sinusitis, in accordance with clinical recommendations, intranasal corticosteroids, elimination therapy, herbal remedies, and antibacterial drugs are used. Due to the period of the SARS-CoV-2 pandemic, a significant proportion of patients took large doses of antibacterial drugs, which caused an increase in the resistance of microorganisms to them. In this regard, it is possible to use immunostimulating drugs that stimulate cellular and humoral immunity, promote the development of a specific immune response and activate nonspecific defense factors such as lysozyme, mucin, lactoferrin and normalize mucociliary clearance. As a rule, the identification of a viral agent is carried out in case of a severe clinical course of the disease or complications from the ORL and other organs, and the use of immunostimulating agents in complex therapy is necessary at the earliest possible time of the disease. In this context, the use of immunostimulants containing polyvalent antigenic complexes, including bacterial lysates, the most common pathogens of respiratory infections, is justified. It is preferable in these cases to use lysates of bacteria obtained by mechanical destruction of bacterial cells, since they have a more pronounced non-specific immunostimulatory and specific vaccinating effect.
