Abstract
Single nucleotide substitutions in gene sequence associated with conformational changes in protein receptor or in expression of interferon receptors may explain variations in human susceptibility to infection and severity of COVID-19 along with other well-known risk factors. The study aimed to investigate associations between polymorphic variants of interferon receptor genes, COVID-19 severity and prevalence of antibiotic resistance genes in the gut microbiota. Materials and methods. The study was conducted using a random sample of Arkhangelsk population aged 42 to 76 years (n = 305). The research involved gathering COVID-19 data from the Federal Register, conducting blood tests for SARS-CoV-2 antibodies and polymorphic interferon receptor gene variants, and identifying antibiotic resistance genes in stool samples. Results. During the first 12–15 months of the COVID-19 pandemic, 17.4% of the study participants had symptomatic COVID-19, while 32.8% were asymptomatic. By the Autumn of 2022, symptomatic COVID-19 cases rose up to 36.4%, while asymptomatic cases increased to 61.3%. We reveal an association between the CC genotype of the IFNAR1 gene rs2257167 variant, the presence of the T allele of IFNAR2 gene rs2229207 variant, the CCTT haplotype and symptomatic COVID-19. The GCTC haplotype was associated with pneumonia and COVID-19 severity. In November 2022, macrolide resistance genes were observed in 98.4% of cases, whereas those to beta-lactams and glycopeptides — in 26.9% and 13.8% cases, respectively. Resistance to three classes of antibiotics was observed in 4.9% and was more frequently detected in individuals with the ССТТ haplotype. Genes encoding beta-lactamases were more often found in individuals with the GCTC haplotype, those who had COVID-19 with pneumonia and those who received hospital treatment. Glycopeptide resistance genes were associated with the CC genotype of the rs2257167 variant of IFNAR1 gene. Conclusion. We identified genetic determinants of susceptibility, symptomatic infection and COVID-19 severity. The associations between polymorphic variants of interferon receptor genes and COVID-19 severity can be used to identify people with a genetic predisposition to severe infection and to determine priority groups for vaccination, including the prevention of antibiotic resistance in complicated course of viral infections.
