Objective: to study the efficacy and safety of antiviraltherapy for influenza and acute respiratory viral infection with Kagocel in children in a hospital. Materials and methods: in the observational study included 80 children aged 3 to 11 years, hospitalized with symptoms of influenza and acute respiratory viral infection. The etiological confirmation of the diagnosis was carried out by the PCR method based onthe study of nasal swabs.The drug Kagocel was administered according to the instructions for use during the first 24 hours of hospitalization.The analysis of the virus release after the course of therapy with Kagocel (at 5–6 days from the beginning of treatment) was carried out only in patients with verified influenza and acute respiratory viral infection. Results: the dominant influence of viruses in the development of acute respiratory infections in children aged 3 to 11 years in the period of rising morbidity in St. Petersburg from September 2015 to May 2016. At the same time, 25% of the total number of patients were sick with influenza A and/or B. There was a significant decrease in fever to the third day (p <0,001) and normalization of body temperature from the fourth day after the beginning of therapy with Kagocel in the general group and in patients with confirmed influenza diagnosis. The intoxication syndrome, most pronounced with the flu, was mostly stopped by the fourth day(р<0,001). Catarrhalsyndrome, prevalent in the general group of acute respiratory viral infection, had longer periods of clinical manifestation and against the background of the therapy completely eliminated to the third or seventh day of therapy.Negative PCR results after the course of Kagocel therapy were established in 57,1% of the total group of patients. Among all detected viruses, the most typical is the absence of repeated isolation of influenza B and A viruses, PC virus (86% and 53,8%, 71,4%, respectively), the elimination of rhinoviruses was less frequent (33,3%). Conclusion: according to the results of the study, the effectiveness of therapy with the inclusion of the drug Kagocel in relieving fever by 3–4 days of treatment, as well as intoxication syndrome by 5–6 days in patients with acute respiratory viral infections, including patients with influenza, has been established. Negative results of PCR at the time of completion of therapy occurred mainly in patients with influenza A and B, PC infection. No adverse events were noted.

Influenza is one of the commonest acute viral respiratory infections with a great potential for spreading as an epidemic or pandemic appearance. Until 2009 relevant data about types and subtypes of influenza viruses circulated in Republic of Macedonia, did not exist. Since pandemic in 2009, molecular method RT-PCR was introduced real time detection of types and subtypes of influenza viruses, which enabled continuously and accurate follow up. Flu differ in types and subtypes presence in each new season, with great influence on number of patients and deaths caused by influenza viral infections. In season 2009/2010 - type Influenza A dominated, subtype A (H1N1) pdm. Total number of 54.343 cases were registered and 30 deaths. In season 2010/2011 – co-circulated types of Influenza A and Influenza B, with small domination of subtype A (H1N1) pdm. Total number of 27.635 cases were registered and 17 deaths. In season 2011/2012 - dominant was type Influenza A, subtype A (H3N2). Total number of 9.732 cases were registered and only one case of death. In season 2012/2013 - co-circulated types of Influenza A and Influenza B, with domination of subtype A (H1N1) pdm. Total number of 24.524 were registered, no deaths. In season 2013/2014 - co-circulated types of Influenza A and Influenza B, with domination of subtype A (H3N2). Total number of 29.074 were registered and 12 deaths. In season 2014/2015 - dominant was type Influenza B, and also Influenza A subtype A(H3N2) circulated. Total number of reported cases was 33.228, no deaths. In season 2015/2016 - Influenza A, subtype A(H1N1) pdm was dominant. During same period, type Influenza B, subtype Victoria was detected as well. Total number of reported cases was 29.094 and 2 deaths. In season 2016/2017 - type Influenza A, subtype A/H3, was dominant. Total number of reported cases was 35.079 and 2 deaths. In season 2017/2018 година – simultaneously circulation of types Influenza А and Influenza B, with domination of lineage B/Yamagata. Total number of 23.954 cases were registered, no deaths. In season 2018/2019 - highest number of cases were caused by type Influenza A subtype A(H1) pdm, in co-circulation with Influenza А(H3). Total number of reported cases was 21.404 and 29 deaths, that present the highest number of deaths in correlation with number of diseased.

: Respiratory infections caused by viruses such as influenza and coronavirus are a serious global problem due to their high infection rates and potential to spark pandemics, such as the current COVID-19 pandemic. Although preventing these infections by using vaccines has been the most successful strategy to date, effective vaccines are not always available. Therefore, developing broad-spectrum anti-viral drugs to treat such infections is essential, especially in the case of immunocompromised patients, or for outbreaks of novel virus strains. Sialic acids have been highlighted as a key molecule in the viral infection cycle, with terminally sialylated glycans acting as a target for several viral proteins involved in infection, particularly respiratory infection. Inhibitors of one such protein, neuraminidase, are the only anti-influenza drugs currently on the market. Problems with neuraminidase inhibitors, including development of resistance and a relatively narrow spectrum of activity, drive the need for an improved understanding of the viral infection cycle and the development of more resilient, broader-spectrum anti-viral treatments. Hence, this review outlines the various roles played by sialic acids in respiratory viral infection and provides examples of drugs that exploit sialic acids to inhibit viral infections. It has been concluded that drugs targeting host cell expression of sialic acid could be especially well suited to inhibiting a broad spectrum of respiratory infections. This warrants the continued design and improvement of such drugs in an attempt to lessen the burden of respiratory infections.

Syncytial Virus

This paper discusses the spread of the most common causative agents for respiratory viral infections, i.e., respiratory syncytial virus (RSV) and influenza virus (IV), during seasonal peaks and under the COVID-19 pandemic. The COVID-19 pandemic and epidemic control measures reduced the transmission of some respiratory viral pathogens. The authors specify the risks of changes in RSV epidemiology associated with restrictions and their lifting. Possible scenarios of virus "behavior" in 2021–2022 are represented. These scenarios include the return of variants registered at the end of 2019 and the risk of the emergence of a novel strain of zoonotic flu that may result in a novel viral pandemic. It was demonstrated that effective monitoring of causative agent circulation, timely specific prophylaxis (particularly in high-risk groups), and early effective antiviral therapy are crucial irrespective of the possible scenario of respiratory viral infection. Modern principles of complex flu and acute respiratory viral infection treatment using an antiviral agent based on rimantadine and sodium alginate are addressed.

Objective: To define the molecular epidemiology of respiratory viral infections in adult patients. Methods: Nasal and throat swabs were collected from all adult patients with influenza-like illness (ILI), acute respiratory infection (ARI), or severe ARI (SARI) admitted to a tertiary hospital in Surakarta, Indonesia, between March 2010 and April 2011 and analyzed for 19 respiratory viruses and for torque teno virus (TTV) and human gyrovirus (HGyV). Results: Respiratory viruses were detected in 61.3% of the subjects, most of whom had ARI (90.8%, OR = 11.39), were hospitalized (96.9%, OR = 22.31), had asthma exacerbation (90.9%, OR = 8.67), and/or had pneumonia (80%, OR = 4.0). Human rhinovirus (HRV) A43 predominated. Influenza A H3N2, human metapneumovirus (HMPV) subtypes A1 and A2, the influenza B virus, human adenovirus B, and human coronavirus OC43 were also detected. All respiratory viruses were detected in the transition month between the rainy and dry seasons. No mixed respiratory virus infection was found. Coinfections of the influenza A H3N2 virus with TTV, HMPV with TTV, HRV with TTV, and human parainfluenza virus-3 with TTV were found in 4.7, 2.8, 19.8, and 0.9% of the samples, respectively. Conclusions: This study highlights the need to perform routine detection of respiratory viruses in adults hospitalized with ARI, asthma exacerbation, and/or pneumonia.

The Relationship

The relationship between viral seroconversions and idiopathic sudden hearing loss (ISHL) is studied. Compared with our control group, the incidence of viral seroconversions is greater among ISHL patients, both for single and multiple viral infections. There was a significantly greater number of patients with seroconversions to mumps, rubeola, varicella-zoster, cytomegalovirus, and influenza B. We were unable to find a relationship between viral seroconversion and type or degree of hearing loss, vertigo, or chance for recovery. The incidences of viral conversion and sudden hearing loss track one another closely, suggesting that viral infection is a major cause of ISHL. During this 3-year study in Boston, ISHL was most prevalent in the spring.

Purpose: To study the clinical aspects of influenza and acute respiratory viral infection (ARVI) in routine clinical practice, with efficacy and safety of the antiviral therapy evaluation. Subjects and methods: In the large multicenter prospective observational study were enrolled 18,946 patients aged 18 to 93 years with previously determined diagnosis of influenza or ARVI from 262 outpatient sites in Russia, Armenia, Moldova and Georgia. According to study design, 3 visits were evaluated. On each visit the detailed medical examination, determination of individual symptoms’ severity and course of disease were made. The dynamic evaluation of prescribed in routine clinical practice therapy of influenza and ARVI and cases of disease exacerbations with antibiotics concomitant therapy were assessed. Results: For the first time in outpatient practice on a large population of adult patients the objective data were obtained and analyzed. This data relating to the timing of access to medical care of patients with influenza and ARVI depending on the age and the disease severity, dynamics of clinical picture of the disease, their outcomes, timing recovery, as well as ongoing drug therapy of ARVI and influenza, allowed to identify patterns of development and course of these diseases. The effectiveness and safety of antiviral drug Kagocel for treatment of ARVI and influenza was shown. This is reflected in the improvement of the clinical picture of the disease; reducing the number of patients with exacerbations, requiring the prescription of systemic antibiotics up to 1.5 times; the acceleration of regression of symptoms and recovery periods. Conclusion: This study allows increase the level of objective assessment of the beginning and course of influenza and other ARVIs in outpatient practice, to predict their course and outcome, and to improve the treatment

SUMMARYViral infections are associated with pulmonary exacerbations in children with cystic fibrosis (CF), but few studies have addressed the frequency in adults. This paper investigates the frequency and impact of viral infections in adults with CF receiving intravenous antibiotics. Pre- and post-treatment spirometry, inflammatory markers and antibody titres against influenza A, influenza B, adenovirus, respiratory syncytial virus, Mycoplasma pneumoniae, Chlamydia psittaci, and Coxiella burnetti were analysed over a 10-year period. Non-bacterial infections were identified in 5·1% of 3156 courses of treatment. The annual incidence of admissions per patient associated with viral infection was 4·9%. The presence of viral infection in association with a pulmonary exacerbation did not adversely affect lung function or inflammatory markers in the short term. Adults with CF have a lower incidence of respiratory viral infections associated with pulmonary exacerbations requiring intravenous antibiotics compared to children and infants with CF.
