Abstract
The main cause of death in patients with cystic fibrosis (CF) is infectious process in the lungs, in particular, chronic lung infections caused by various pathogens, most often a combination of bacteria, fungi, or viruses. Data on mixed bacterial and viral-bacterial infections from domestic and foreign sources are fragmentary and sparse. The dominant associations of bacterial and viral pathogens in patients with cystic fibrosis have not been studied properly, and data on their epidemiological significance are lacking. The aim of this study was to assess the prevalence of bacterial and viral infections in patients with cystic fibrosis and to substantiate the need for the development of virological monitoring. Methods. Biomaterials from the respiratory tract of CF patients (409 children and 160 adults with CF) examined from 2006 to 2022 were used. The study was carried out using bacteriological methods, molecular genetic methods (RT-PCR) and MALDI-TOF mass-spectrometry. Results. Microflora of the respiratory tract was shown to be mixed in 2/3 patients with CF. The microflora of the lungs of children with CF is a dynamic community of microorganisms with high diversity and variability. In adult patients, associations of microorganisms are more common than in children, but the composition of associations is less diverse. We isolated about 40 species of bacteria from adult patients and more than 85 species from children in our sample. NFMO prevailed, including Burkholderia cepacia complex, Pseudomonas aeruginosa, Achromobacter xylosoxidans, Achromobacter ruhlandii, Stenotrophomonas maltophilia, and Staphylococcus aureus, Candida albicans, Aspergillus spp. Real-time PCR showed the presence of rhinovirus RNA in 10% of samples obtained from children and 12.9% from adults with cystic fibrosis. Conclusion. Our results indicate the need for continuous monitoring of the lung microflora in patients with CF, including testing for viruses.
