Respiratory Viral Infections

Aim. To study the incidence of acute respiratory infections (ARI) in medical staff of dental clinics.Materials and Methods. We performed a descriptive, retrospective epidemiological study of ARI incidence by means of conducting an anonymous survey of 1,081 dentistry practitioners (358 in specialised dental clinics and 723 employees of polyclinics) in Kemerovo (2020). ARI included COVID-19, community-acquired pneumonia, and other common respiratory viral infections. The questionnaire included 12 questions about ARI, age, gender, working experience, and position.Results. The incidence of ARI in dentistry practitioners in specialised dental clinics was 2.6-fold higher as compared with those working in polyclinics [379.52 per 1,000 (95% CI = 327.10-434.11) and 146.19 per 1,000 (95% CI = 120.56-174.93), respectively, p = 0,00001], regardless of age. Prolonged and close contact with the patients along with an intensive use of aerosol-generating technologies were associated with a 2.3-fold times higher incidence of ARI in dental therapists in comparison with dental surgeons. Female dentists suffered from ARI 1.8-fold more frequently than males [410.91 per 1,000 (95% CI = 352,18-471,58) and 228.07 per 1,000 (95% CI = 127.40-358.36), p = 0,01] but most women worked as dental therapists that could confound such association. ARI incidence was not associated with age, work experience, and position (p = 0.22).Conclusion. Dentistry practitioners working in specialised clinics more frequently experienced ARI than those working in polyclinics. Dental therapists were at higher risk of ARI in comparison with dental surgeons, potentially due to the active use of aerosol generating technologies and prolonged close contact with the patients during treatment. Other factors were not among the major determinants of ARI incidence in dentistry practitioners.

Respiratory Viral Infections

Пневмония – острое инфекционно-воспалительное заболевание легких преимущественно бактериальной этиологии, характеризующееся выраженной в разной степени дыхательной недостаточностью, токсическими и респираторными нарушениями, локальными физикальными симптомами, а также инфильтративными изменениями на рентгенограмме. Заболеваемость внебольничными пневмониями повышается в октябре-декабре, достигая максимума в январе-апреле, коррелируя с сезонным повышением уровня острых респираторных вирусных инфекций. Схожесть симптомов дебюта пневмонии с проявлениями острых респираторных вирусных инфекций может привести к несвоевременной ее диагностике и, как следствие, к отсроченному началу лечения. Поэтому в период сезонной заболеваемости респираторными инфекциями должна повышаться настороженность врачей-педиатров в отношении внебольничной пневмонии. Антибактериальная терапия оказывает решающее влияние на прогноз пневмонии, поэтому при достоверном диагнозе или у больного в тяжелом состоянии с вероятным диагнозом ее следует начать незамедлительно. Выбор антибиотика в каждом случае внебольничной пневмонии проводят индивидуально с учетом природной активности препаратов в отношении предполагаемого возбудителя и их возможной приобретенной резистентности, тяжести и течения заболевания, наличия у пациента противопоказаний к использованию тех или иных антибиотиков. В статье приводятся сведения о диагностических критериях внебольничных пневмоний. Рассмотрены вопросы антибактериального лечения типичной нетяжелой пневмонии у детей разных возрастных групп амоксициллином с клавулановой кислотой и показана его эффективность. Результаты проведенного исследования позволяют заключить, что пероральное использование одного курса защищенного аминопенициллина эффективно при лечении типичной внебольничной нетяжелой пневмонии у детей разного возраста, о чем свидетельствует ликвидация основных клинических проявлений болезни в короткие сроки. Pneumonia is an acute infectious and inflammatory lung disease of predominantly bacterial etiology, characterized by respiratory failure, toxic and respiratory disorders, local physical symptoms, and infiltrative changes on the roentgenogram. The incidence of community-acquired pneumonia increases in October-December, reaching a maximum in January-April, correlating with the seasonal increase in the level of acute respiratory viral infections. The similarity of the symptoms of the onset of pneumonia with the manifestations of acute respiratory viral infections can lead to its untimely diagnosis and, as a consequence, to a delayed start of treatment. Therefore, during the period of seasonal morbidity with respiratory infections, the alertness of pediatricians in relation to community-acquired pneumonia should increase. Antibiotic therapy has a decisive influence on the prognosis of pneumonia, therefore, with a reliable diagnosis or in a patient in serious condition with a probable diagnosis, it should be started immediately. The choice of antibiotic in each case of community-acquired pneumonia is carried out individually, taking into account the natural activity of the drugs in relation to the alleged pathogen and their possible acquired resistance, the severity and course of the disease, the patient's contraindications to the use of certain antibiotics. The article provides information on the diagnostic criteria for community-acquired pneumonia. The issues of antibacterial treatment of typical non-severe pneumonia in children of different age groups with amoxicillin with clavulanic acid are considered and its effectiveness is shown. The results of the study allow us to conclude that the oral use of one course of protected aminopenicillin is effective in the treatment of typical community-acquired non-severe pneumonia in children of different ages, as evidenced by the elimination of the main clinical manifestations of the disease in a short time.

The aim: to study the etiological structure of acute respiratory infections in children aged 3 to 12 hospitalized in the early stages of the disease in the department of respiratory infections of the children’s hospital, and to reveal the features of their clinical course and the timing of DNA / RNA elimination of respiratory viruses from nasal secretions, depending on the method of therapy. Materials and methods: 100 children with acute respiratory infections aged 3 to 12 years were monitored. The nasal secrets on the DNA / RNA of respiratory viruses were studied by PCR. Depending on the method of therapy, patients were divided into 2 groups: patients of group 1 (comparison) received basic treatment (without the use of antiviral drugs), in patients of the 2nd group (main), along with basal therapy, the drug was used umifenovir in a 5-day course at the ageappropriate dosage. Results: In the etiologic structure of ARVI in children from 3 to 12 years, the leading place was taken by rhinovirus, influenza and metapneumovirus infections (isolated – 18%, 19% and 20% respectively, in the form of a mixed infection – 11%). The main syndromic diagnosis at the height of the disease was rhinopharyngitis. Complications were observed in 42% of cases, as often as possible with flu – 53% of cases. Features of metapneumovirus infection in children of this age group were: predominance of non-severe forms of the disease in the form of acute fever with symptoms of rhinopharyngitis, as well as a small incidence of lower respiratory tract infections. The use of the drug umiphenovir in children with acute respiratory viral infections of various etiologies contributed to significantly faster elimination of viral DNA / RNA from the nasal secretion, which was accompanied by a ecrease in the duration of the main clinical and hematological symptoms of the disease, a decrease in the incidence of complications, and reduced the duration of stay in hospital. Conclusion: application of modern molecular genetic methods of diagnostics made it possible to identify the leading role of influenza, metapneumovirus and rhinovirus infections in the etiology of acute respiratory viral infection in patients aged 3 to 12 years, and to determine a number of clinical features characteristic of this age group. The results of the study testify to the effectiveness of umiphenovir in the treatment of children with acute respiratory viral infections of various etiologies and allow us to recommend this drug as an effective and safe etiotropic agent.

Respiratory viruses are the leading cause of pediatric morbidity and mortality worldwide. Rapid identification of a pathogen, epidemiological surveillance, description of symptoms, and the development of preventive and therapeutic measures are keystones to limit the spread of respiratory infections. Novel viruses with specific properties are regularly discovered. This paper addresses essential data on the most common viruses provoking acute respiratory infections, including whose in children and the pattern of their course. Conventionally, the most vital concern is flu. Influenza viruses provoke seasonal outbreaks, epidemics, and pandemics. Many studies demonstrate the role of rhinovirus C in the development of bronchiolitis and, subsequently, asthma. Severe acute respiratory syndrome-related coronavirus (SARS-CoV), Middle East respiratory syndrome-related coronavirus (MERS-CoV), and SARS-CoV-2 provoking COVID-19 were recently described. Knowledge of known and newly emerging viruses is crucial for timely adequate medical care. The authors discuss major therapeutic strategies for acute respiratory infections that provide a more favorable course of infectious inflammation irrespective of viral etiology.

Aim: to evaluate the efficacy and safety of Anaferon and Anaferon for children for the prevention and treatment of of acute respiratory viral infections (ARVI)/influenza using meta-analysis. Patients and Methods: the meta-analysis included data from 11 randomized clinical trials (RCTs) involving 3079 patients aged 1 month to 69 years, of which: 1729 people were included in the meta-analysis of the preventive drugs efficacy, 1550 patients — in the meta-analysis of the therapeutic efficacy of Anaferon for children. The evaluation of the therapeutic efficacy was conducted according to the criteria "disease duration" and/or "fever duration", the evaluation of the preventive efficacy was conducted according to the criterion "the proportion of patients not falling ill with ARVI/influenza". The safety was evaluated taking into account the number of adverse events (AEs). Statistical methods included the exact Fisher criterion, the Student criterion, fixed and random effects models, the Z-test, the Cochrane-Mantel-Hensel criterion, Cochrane Q-statistics and the I2 coefficient, the Breslow-Day test, the calculation of relative risk (RR), odds ratios (OR) and their 95% confidence intervals (CI). Results: according to the criterion "the proportion of patients not falling ill with ARVI/influenza", the RR of Anaferon for children was 1.2 [95% CI 1.2; 1.3] with an OR of 2.2 [95% CI 1.7; 2.9], while for Anaferon, the RR was 6.7 [95% CI 3.8; 11.8] with an OR of 20.1 [95% CI 9.2; 44.0]. At the same time, the proportion of patients without ARVI/influenza during Anaferon intake exceeded that in the absence of preventive intervention by almost 8 times, and during Anaferon for children intake — 1.3 times vs. placebo. When evaluating the therapeutic effect of Anaferon for children, it was found that the average disease duration was 1.4 times shorter than during placebo intake, and was 4.71±2.53 days (p<0,001). The average fever duration was 2.19±1.21 days vs. 3.22±1.81 days during placebo intake (p<0,001). According to the criterion "disease duration", the weighted average effect value was 1.05 [95% CI 0.44; 1.67], according to the criterion "fever duration" — 0.97 [95% CI 0.61; 1.33] (p<0.001, p-value of the two-tailed Z-test; random effects model). The therapeutic efficacy of Anaferon for children did not depend on the etiology of ARVI, the symptoms, and the presence of comorbidity (asthma). The total number of AEs is similar to those in the comparison group. Conclusion: the conducted review and meta-analysis concerning the efficacy and safety of Anaferon and Anaferon for children for the treatment and prevention of ARVI/influenza allow us to conclude the following: 1) Anaferon for children is effective and safe for the treatment of influenza and other acute respiratory infections, regardless of the pathogen and the presence of comorbidity (asthma); 2) Anaferon and Anaferon for children are effective and safe for the prevention of acute respiratory infections/influenza, including patients with concomitant bronchopulmonary pathology and frequently ill children.

Respiratory Viral Infections

Acute respiratory viral infections represent a group of clinically, pathomorphologically similar acute inflammatory respiratory diseases that manifest by fever, a runny nose, sneezing, cough, sore throat, a general feeling of ill health of varying severity. Activation of latent, persistent infections of viral and/or bacterial origin may occur in recurrent respiratory infections. Decreased production of local immunity contributes greatly to the development of viral and bacterial infections, persistence of pathogenic micro-organisms. Intestinal microflora can directly or indirectly affect the human respiratory tract through increased production of cytokines, short-chain fatty acids. In recent years, there has been a scientific interest in the therapeutic potential of probiotics for the prevention of acute respiratory viral infections. Earlier studies have shown a positive effect of probiotics on the respiratory tract with a view to prevent and reduce the incidence and severity of respiratory infectious diseases by expending the number of IgA secreting cells in the bronchial mucosa. Studies showed that the use of probiotics can reduce the incidence of acute respiratory infections, duration of fever, cough, and the need for antibacterial agents in children. Peptidoglycans and muramyl peptides that are constituents of the bacterial cell wall have antiviral activity. Probiotics can also inhibit virus attachment through a process of competing for the specific receptors. The regeneration of the mucous membrane is enhanced by the ability of mucin to prevent the virus from attaching to epithelial cells and suppress virus replication. The antiviral effect of probiotics may be caused by the ability to produce antimicrobial peptides, dehydrogenases and NOs. Probiotics can modulate the functions of epithelial and dendritic cells, CD4 +, CD8 + T lymphocytes, NK cells, stimulate the synthesis of secretory immunoglobulins, helping to neutralize the virus.

The influenza and acute respiratory infections are one of the medical problems. The relevance of influenza and acute respiratory infections was due to the lack of a persistent immune response and the lack of vaccines against many respiratory viral infections. We have analyzed the latest outbreak of influenza and acute respiratory infections in the North Ossetia-Alania, that occurred in winter 2015. During the analyzed period there was an increase in the incidence of acute respiratory infections by 42,1%. 66 cases of influenza were revealed by the laboratory. In order to reduce the intensity of flu and acute respiratory infections is necessary to observe all types of preventive measures: specific vaccination, chemoprophylaxis with antivirals and following the rules of non-specific prevention.
