According to modern ideas about the mechanisms of antiviral protection, in addition to humoral, mainly due to antibodies, antiviral protection is largely due to the activation of innate immune factors, both systemic and local.\u0000Aim: to evaluate in the dynamics of observations the influence of a single parenteral influenza vaccination on the factors of innate immunity in patients with chronic inflammatory diseases of the upper respiratory tract.\u0000Material and methods: Among the factors of innate immunity a significant role is played by interferons, the activity of natural cytolytic cells (NK) of various histogenesis, phagocytic cells and non-specific proteins such as defensins, elafins. Therefore, quantitative and functional characteristics of NK-cells, phagocytic absorption activity of polymorphonuclear leukocytes (PMN), systemic content of γ-interferon (IFN-γ) were studied in patients at the systemic level. At the local level, the concentrations of defensin-β and α-interferon were studied in mucosa secretes (MS) according to modern ideas about the state of the mechanisms of innate antiviral immunity.\u0000From the autumn-winter period of 2019 to November 2020, 32 donors (control group) and 32 patients with CID of both sexes were examined, 11 of whom were diagnosed with chronic rhinosinusitis, 9 with chronic tonsillitis, and 12 with chronic pharyngitis. No vaccinations were given 1 year before the study.\u0000Samples of venous serum and oropharyngeal secretes of all clinically healthy patients, as well as persons with CID were obtained at the initial examination. After parenteral vaccination with Vaxigrip (SANOFI PASTEUR, S.A., France), blood and MS were tested twice more in vaccinated patients: 12 and 36 weeks after vaccination. The obtained samples of experimental material were stored at a temperature of -20 C◦ until the simultaneous determination of innate immune factors (interferons), in particular with the help of reagents from Cytokine, Hema Medica (RF), defensin-β (Hucalt-bio, the Netherlands). Measurements were performed on a microplate enzyme-linked immunosorbent assay \"STAT FAX 2100 (USA).\u0000Statistical processing was performed using the non-parametric criterion \"U\" - Mann-Whitney or Fisher's exact method. Differences were considered statistically significant at p <0.05. The results were given in the form of arithmetic mean (M), median (Me) and percentiles (P25-P75).\u0000Results: In determining the role of innate immunity factors in vaccination with influenza vaccine, we conducted clinical and immunological examination of patients with chronic inflammat","PeriodicalId":38742,"journal":{"name":"Otorhinolaryngology Clinics","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89618562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
