Corynebacteria non-diphtheria and, in particular, C. pseudodiphtheriticum species that are closely related to C. propinquum and C. striatum form a group of new respiratory pathogens leading to the development of bronchitis, tracheitis, exacerbation of chronic obstructive pulmonary diseases, nosocomial pneumonia and other pathology. The goal is to analyze the frequency of the release of Сorynebacteria non-diphtheria from the upper respiratory tract of patients with various inflammatory diseases of the respiratory tract. Strains of Сorynebacteria non-diphtheria (C. pseudodiphtheriticum, C. propinquum, C. accolens, et al.), isolated from patients with inflammatory diseases of the respiratory tract (60 pcs.) and practically healthy individuals (31 pcs.) were studied. Identification of Сorynebacteria was performed using the method of mass spectrometry (MALDI-ToFMS). Сorynebacteria non-diphtheria in the amount of 105 and higher were more frequently detected with the development of chronic tonsillitis (60.0%) and nasopharyngitis (30%). The strains of C. pseudodiphtheriticum (40.0±6.4%) and the closely related species C. propinquum (21.7±5.3%) were mainly found; much less often - C. accolens (8.3±3.6%), C. afermentans (6.7±3.3%), et al. In 86.7% of cases, Corynebacteria non-diphtheria were isolated from children. In chronic tonsillitis, C. pseudodiphtheriticum and the closely related species of C. propinquum were isolated more often; in nasopharyngitis and bronchitis - С. pseudodiphtheriticum. Isolation of Corynebacteria non-diphtheria and, especially, C. pseudodiphtheriticum, C. propinquum, C. accolens species from patients with inflammatory diseases of the respiratory tract in the amount of 105 and above, if there are no other pathogenic microorganisms in the role of microbial associates, of clinical importance.

Bacteriophages - viruses infecting bacteria are the largest known group of viruses, which in their structure mainly have doublestranded genomic DNA, but among them there are also groups with double-stranded RNA and single-stranded DNA and RNA. The total population is about 1031–1032 phages, they play an essential role in the regulation of the world’s number of bacteria. The rather complex and diverse interaction of these representatives of the microcosm continues throughout the history of their existence on our planet. The question of the use of bacteriophages in the treatment of patients with various bacterial infections still remains completely unexplored. The very idea of using these microorganisms for therapeutic purposes dates back to the First World War, when the French biologist and researcher Felix d’Hérelle discovered a special type of «bacteria-eating» viruses, on the basis of which he created drugs for the treatment of patients with dysentery. To date, a fairly large clinical experience has been accumulated in the use of phage preparations in the treatment of infectious and inflammatory diseases of the respiratory, gastrointestinal, urogenital tract, as well as in the therapy and prevention of purulent-septic processes and nosocomial infections. The mucous membrane of the upper respiratory tract is the first line of defense against various respiratory pathogens. The ability of bacteriophages to attach to the surface layer of mucus - mucin, forming an antibacterial protection of the mucous membrane and thus reducing the level of colonization of mucus by bacterial pathogens, determines their effective use in the treatment and prevention of inflammatory diseases of the upper respiratory tract. Due to certain unique properties of bacteriophages, peculiarities of vital activity and interaction with a bacterial cell, their use seems to be promising for the treatment of patients with infectious diseases of the upper respiratory tract.

ABSTRACT The closely related species of the Lactobacillus casei group are extensively studied because of their applications in food fermentations and as probiotics. Our results show that many strains in this group are incorrectly classified and that reclassifying them to their most closely related species type strain improves the functional predictive power of their taxonomy. In addition, our findings may spark increased interest in the L. casei species. We find that after reclassification, only 10 genomes remain classified as L. casei. These strains show some interesting properties. First, they all appear to be catalase positive. This suggests that they have increased oxidative stress resistance. Second, we isolated an L. casei strain from the human upper respiratory tract and discovered that it and multiple other L. casei strains harbor one or even two large, glycosylated putative surface adhesins. This might inspire further exploration of this species as a potential probiotic organism. Although the genotypic and phenotypic properties of the Lactobacillus casei group have been studied extensively, the taxonomic structure has been the subject of debate for a long time. Here, we performed a large-scale comparative analysis by using 183 publicly available genomes supplemented with a Lactobacillus strain isolated from the human upper respiratory tract. On the basis of this analysis, we identified inconsistencies in the taxonomy and reclassified all of the genomes according to their most closely related type strains. This led to the identification of a catalase-encoding gene in all 10 L. casei sensu stricto strains, making it the first described catalase-positive species in the Lactobacillus genus. Moreover, we found that 6 of 10 L. casei genomes contained a SecA2/SecY2 gene cluster with two putative glycosylated surface adhesin proteins. Altogether, our results highlight current inconsistencies in the taxonomy of the L. casei group and reveal new clade-associated functional features.

Increase in the number of acute and chronic diseases is a global trend. On the one hand, the emergence of new types of viruses, their active mutation, an increase in antibiotic-resistant bacterial strains, a high frequency of immunodeficiency and allergic diseases contribute to this. On the other hand is inadequate treatment of inflammatory diseases of the upper respiratory tract, widespread use of systemic antibiotics without indications. The use of bioregulatory medicines with proven efficacy in the complex treatment can reduce the drug load on the body, reduce the bacterial complications and side effects. Traumeel®S joins the physiological course of inflammation and activates pro-resolving mediators, contributes to its faster completion and tissue repair. The efficacy and safety of Traumeel®S has been confirmed in many randomized clinical trials. The drug has proven its value in almost any inflammatory pathology of the upper respiratory tract and ear. The drug Lymphomyosot®, a multicomponent agent with lymphatic drainage action, has proven itself perfectly in the complex therapy of chronic tonsillitis. In November 2019, the Council of Experts of the National Medical Association of Otorhinolaryngologists on the problems of pathology of the lympharyngeal ring was held. It is recommended to use the multicomponent bioregulatory preparation Traumeel®S to correct the inflammatory process, which has shown in studies a modulating effect on inflammatory mediators without suppressing COX-2 (prostaglandins). With exacerbation of chronic tonsillitis and lymphadenitis of nonspecific etiology, it is possible to use the multicomponent preparation Lymphomyosot®, which helps to improve the drainage and detoxification function of the lymphatic system.

Alumina refineries are among the leading sources of atmospheric air pollution with a wide range of pollutants hazardous to human respiratory organs. It is relevant to study and evaluate the occurrence of the risks for development of respiratory diseases in children living in the area affected by the emission components of an alumina refinery. We assessed air quality of the area under observation and comparison according to monitoring observations, risk of non-carcinogenic effects from the respiratory organs. The content of chemicals in the blood and urine adequate to risk factors was quantified. The structure of individual groups of respiratory diseases was analyzed. The causal relationships of violations of laboratory parameters with an increased content of chemicals in biological media were evaluated. It was found that an aerogenic exposure of chemical pollutants is formed on the territory with the production of metallurgical alumina. It determines the risk for development of respiratory diseases, exceeding an acceptable level up to 49.9 times. In the exposed children, the content of manganese, chromium, nickel, copper, xylenes, formaldehyde and aluminum, fluoride ion in the urine was increased to 4.2 times in relation to the indices in the comparison group. A high level of additional respiratory morbidity(1.8 times) was revealed. Chronic lymphoproliferative diseases of the nasopharynx and inflammatory diseases of the upper respiratory tract (up to 6.6 times more often), inflammatory diseases with a predominance of the mechanism of allergic inflammation ( up to 2.1 times more often)are more often detected in the framework of the respiratory diseases. Negative effects on the part of the respiratory system in the form of activation of antioxidant processes, the development of an inflammatory reaction, local, general and specific sensitization of the respiratory tract were established. It confirms the occurrence of the risks for the development of respiratory diseases in children in the exposure area of the chemical factors of alumina refinery-associated economic activity.

Currently, a rise in incidence of polyethological inflammation of the upper respiratory tract mucosa paralleled by altered resident and transient microbiota displaying in many cases increased antibiotic resistance has been noted. Opportunistic microbes play a major role in developing inflammatory process in Pirogov–Waldeyer’s ring. An inflammatory process occurring in the tonsillar lymphatic tissue results in host systemic complications. Fighting against acute and chronic infections of the upper respiratory tract holds the main task in pediatric otorhinolaryngology, as they can consequently elicit the cardiovascular, genitourinary and musculoskeletal complications. The results of studies examining this issue remain very contradictory, which accounted for a need to conduct our study on the territory of Moldova featured with mixed climatic conditions. Here, we wanted to study a role of microbial factor in etiopathogenesis of chronic tonsillitis in children. Bacteriological microbiota data for superficial palatine tonsils were obtained form 608 children subdivided into 5 groups: group I — 333 children with compensated chronic tonsillitis; group II — 87 children with decompensated chronic tonsillitis; group III — 91 children with acute upper respiratory tract infections (comparison group); group IV — 48 children with acute upper respiratory tract infections treated with antibiotic therapy; group V — 49 apparently healthy children (control group). It was found that β-hemolytic streptococcus exerting high sensitivity to virtually all antibiotics groups was detected in 17.4% of children with acute tonsilar inflammatory processes and decompensated defense in the lymphatic pharyngeal ring compared to 3.5% in control group. Streptococcus pneumoniae was isolated in all study groups ranging within 4.8–21.7%, including 14% in apparently healthy children characterized by reduced antibiotics sensitivity. The data obtained suggest that sickly children with acute and chronic upper respiratory tract infections constitute a risk group for developing somatic diseases. The high incidence of Streptococcus pneumoniae indicates a need for performing immunoprophylaxis, use of therapeutic vaccination as a up-to-date, combined approach in treatment of such pediatric cohort.

Abstract The human gastrointestinal tract is the largest immune organ in the body and consequently influences the overall immune state of all body sites. The gut also harbors the largest proportion of the microbiome. In early life, the maturation of the microbiome and immune system are closely entangled, forming a homeostatic system that imparts individuality and stability to the host microbiome. It is now well established that factors that affect early life gut microbiota modulate susceptibility to chronic inflammatory diseases, including airway diseases such as asthma and allergy. Despite this global influence of the gut on immune response in the lungs, local microbiome-immune interactions also shape the response and susceptibility to disease in the airways. The upper respiratory tract and lung microbiomes also contribute to acute and chronic airway diseases. Modulating the gut-lung axis as well as respiratory tract through microbiome-targeted interventions to promote health and reduce susceptibility to infection and chronic inflammatory disease may represent an effective strategy, particularly in early and late life.

Infectious and inflammatory diseases of the respiratory tract in children are the «leaders» among all pathologies of childhood. Optimization of therapeutic and prophylactic approaches for infectious and inflammatory pathologies of the respiratory system by reducing the frequency of unreasonable antibiotic therapy and eliminating polypragmatic use is a relevant problem of modern pediatrics and otolaryngology. According to WHO guidelines, modern standardized herbal medicines are not inferior in efficiency to synthetic ones. The aim — to analyze the results of assessment by doctors of the preventive and therapeutic efficacy of the remedy «Alpicol» on the basis of a questionnaire, as well as clinical examination of patients before using the medication and after completion of the course of treatment. Materials and methods. The advantages of «Alpicol» were analyzed through a questionnaire offered by first contact practitioners to children in order to receive feedback on the assessment of the preventive and therapeutic efficacy of this medication. Doctors from 9 regions of Ukraine were involved, and 6,093 questionnaires of children of different ages were analyzed. Results. The frequency of registration of a pronounced paediatric pain (3 scores) with the use of the «Alpicol» medication significantly decreased (23.7 times), a moderate manifestation of the disease (2 scores), was 17 times less at the same time, mild manifestations of paediatric pain remained at the same level. Patients with a comorbid pathology of the respiratory tract in the form of recurrent lesions of the upper and lower airways during the 2nd visit received a zero score (no symptoms) significantly less frequently than children with pathology of the upper respiratory tract with 62.6% of cases versus 72.2% of observations, respectively (p<0.05). As a result of the use of the course of «Alpicol» medication, a statistically significant decrease in the severity of the catarrhal symptom complex was achieved, since the proportion of the course of disease, assessed by the maximum number of scores, decreased by 29.6 times, moderate (score 2) — 13.3 times, and zero scores appeared 5.7 times more often. At the same time, the proportion of patients with a mild course of catarrh practically did not change. Conclusions. «Alpicol» has a multi;vector efficacy against the complex of symptoms that accompany infectious and inflammatory exacerbations of recurrent respiratory diseases. This is manifested by a decrease in the severity of clinical manifestations of the disease, as well as in an increase in cases of clinical stabilization of the patient's condition, which demonstrates the therapeutic and prophylactic effect of the drug «Alpicol» on the course of recurrent respiratory diseases in children. The study was carried out in accordance with the principles of the Declaration of Helsinki. The study protocol was adopted by the Local Ethics Committee of all institutions indicated in this research. The informed consent of parents and children was obtained. The authors declare that they have no conflicts of interest. Key words: ecurrent respiratory diseases, treatment and prevention, children, phytocomplexes.

The article provides data on the effectiveness of the use of the drug in the treatment of acute, chronic and recurrent diseases of the respiratory tract and ENT organs. The drug is an extract of Pelargonium sidoides. From the standpoint of modern pharmacology, it is known that the use of natural products based on plant materials ensures safety and the absence of pronounced side effects. The main active ingredients of pelargonium are phenolic compounds: coumarins, flavonoids and phenolic acids. The article details the biochemical and pharmacological properties of each of the above groups of compounds. It has been shown that the presence of several classes of phenolic compounds simultaneously contributes to the potentiation of the pharmacological effects of each group separately. Therefore, drug has a pronounced polytropic effect: antiviral, antibacterial, immunomodulatory, mucolytic, anti-inflammatory, antioxidant, cytoprotective. The article presents the results of numerous domestic and foreign randomized, placebo-controlled studies demonstrating its high efficacy and safety in the treatment of ENT diseases, upper respiratory tract infections and bronchitis, not only in adults, but also in children over 1 year old. On the basis of the analyzed and presented material, the authors concluded that the use of a natural-based drug in the treatment of acute respiratory infection is effective and safe, both as monotherapy and in combination with other medicinal substances. He is able to quickly eliminate not only the symptoms of inflammation, but also to support the body with any ailments of this type.
