    Published 2024-10-01
    “…The overall immunological reactivity of the body of patients with coronavirus infection increases in the presence of the wild-type T-allele of the eNOS gene (rs2070744) in the patient's genotype, especially the CC genotype, by 21.98-57.89% (p≤0.029-0.001), against the background of a decrease in the index of nonspecific reactivity and the ratio of agranulocytes to ESR – by 23.0 (p=0.039) and 15.74% (p=0.044), indicating the onset of specific immunological reactions in the active infectious process. Carriers of the mutational A-allele of the FGB gene (rs1800790) and the TT genotype of the TMPRSS2 gene (rs12329760) showed higher immune reactivity and resistance, which was significantly confirmed by the level of increase in immune reactivity by 6.31-17.21% (p=0.007) and 22.05-35.78% (p≤0.06-0.004), respectively, against the background of a slightly higher rate of allergy (especially in owners of the AG genotype of the FGB gene – by 68.18%, PAG=0.017), a higher ratio of agranulocytes and ESR – by 18.30-21.84% (p≤0.008-0.007) and 19.46-31.07% (p=0.023), with a higher ratio of lymphocytes and eosinophils – by 13.35-19.20% (p≤0.002-0.001). …”
