A novel human enterovirus C (EV-C118) identified in two children hospitalised because of acute otitis media and community-acquired pneumonia in Israel

Objective: to analyze the incidence of community-acquired pneumonia and acute otitis media in children during the first four years of life in different age groups vaccinated with pneumococcal 13-valent vaccine Prevenar.Materials and methods: medical records of 590 children aged 1 to 5 years were analyzed. All subjects were divided into 2 groups. The first group consisted of vaccinated children (n = 490), born in 2014, and vaccinated against pneumococcal 13-valent vaccine Prevenar. The second group consisted of unvaccinated children (n = 100) born in 2013 and not vaccinated. Each group was divided into subgroups depending on the age period (1—2 years, 2—3 years, 3—4 years, 4—5 years).Results: it is established that the conduct of specific prophylaxis of pneumococcal infection vaccine Prevenar-13 in children during the first 4 years of life effectively reduces the incidence of community-acquired pneumonia (in 7,6 times) and acute otitis media (in 8,5 times). The effectiveness of the vaccine was observed in all age groups. In cases of development of an inoculated child acute otitis reduces the risk of severe forms and complications of the disease. Analysis of the course of the post-vaccination period indicates a high level of safety and good tolerability of the vaccine.Conclusion: Implementation of specific prophylaxis of pneumococcal 13-valent vaccine Prevenar in children during the first four years of life according to the calendar of vaccination effectively reduces the incidence of community-acquired pneumonia (87 %) and acute otitis media (42,8 %) in all age subgroups. In cases of development of an inoculated child acute otitis reduces the risk of severe forms and complications of the disease. Analysis of the course of the post-vaccination period indicates a high level of safety and good tolerability of the vaccine.

Background.After inclusion of pneumococcal vaccination in the National Vaccination Schedule, it is very important to evaluate the efficacy of routine immunisation of the child population for more than 3 years. The obtained results provide opportunity to analyse the problems in achieving the goal, determine their causes, and suggest the ways of overcoming. Our aim was to study the results of a three-year period of pneumococcal vaccination of children.Methods.The quality of immunoprophylaxis of pneumococcal infection in the territory of the Russian Federation were assessed by analysing the coverage of vaccination and timeliness of its conduct after the inclusion of pneumococcal vaccine in the National Vaccination Schedule. The actual epidemiological efficacy of pneumococcal vaccination was assessed based on morbidity and mortality due to community-acquired pneumonia, incidence of acute otitis media among children. By questioning parents (n = 352) who applied to the Federal State Autonomous Institution of the Russian Federation Ministry of Health ‘National Medical Research Centre for Children’s Health, the timeliness of pneumococcal vaccination for infants was established.Results.In most regions, a high level of pneumococcal vaccination coverage was reached (87% of children). Despite the fact that the majority of children (73%) were vaccinated untimely. In particular, the results of a questionnaire survey conducted in the Moscow vaccination centre indicate insufficient awareness of parents for the need to vaccinate infants against pneumococcal infection by primary care professionals and, as a consequence, a low level of timely initiated vaccine introduction (40.1%). The introduction of routine prophylactic pneumococcal vaccination in Russia resulted in a 35% reduction in the death rate of children from community-acquired pneumonia, led to a decrease in the incidence of acute otitis media.Conclusion.The introduction of routine prophylactic vaccination of children against Streptococcus pneumoniae helps to reduce morbidity and mortality from pneumococcal infections. The surveillance system for community-acquired pneumonia requires further improvement. It is advisable to conduct an additional analysis on the reasons for refusals and medical exemptions to vaccination. It is important to increase the professional level of paediatricians in prophylactic vaccination.

Background. Vaccination of infants with 13-valent pneumococcal conjugate vaccine (PCV) was implemented in national immunization schedule in 2014. In this regard epidemiological monitoring of routine immunization results with vaccination coverage and efficiency control is required. Objective. Our aim was to study correlation between pneumococcal disease routine immunization in infants and morbidity and mortality rates due to community-acquired pneumonia in children under 18 years of age and morbidity rate due to acute otitis media in children under 14 years of age. Methods. Morbidity (Form № 2, 2011–2017 yrs) and mortality (Form № 51S, 2009–2017 yrs) rates due to community-acquired pneumonia, morbidity rate (Form № 12, 2009–2017 yrs) due to acute otitis media, vaccination coverage rate (Form № 5, 2014–2017 yrs, and Form № 6, 2016–2017 yrs) were analysed according to the data of Forms of Federal Statistical Monitoring. Medical exemptions and refusals to vaccinate rates were estimated according to the data from doctors who was performing infants vaccination. Results. During PCV routine vaccination within national immunization schedule in Russian Federation the 35% reduction of mortality due to community-acquired pneumonia in children under 1 year of age as well as reduction of morbidity with acute otitis media have been established. Moreover, low percentage of etiology clear community-acquired pneumonias (29%) complicates the estimation of vaccination efficiency. It has been revealed that despite the high pneumococcal disease vaccination coverage rate of infants under 2 years of age (87%), considerable part of children (73%) are vaccinated untimely in most Russian Federation regions. 9.3% (3.4% due to medical exemptions) of children (among 1st year infants) remained unvaccinated due to medical exemptions and refusals to vaccinate in 2016, and 8% (3.4%) in 2017 respectively. Conclusion. Implementation of PCV routine immunisation for three years in a row leads to reduction of morbidity rate due to acute otitis media among children under 14 years of age and infant mortality rate due to community-acquired pneumonias. Though, the estimation of routine immunisation efficiency can be difficult due to such factors as untimely start of vaccination, medical exemptions and refusals to vaccinate and limited laboratory diagnostics of community-acquired pneumonias etiology.

Objective. To estimate the prevalence of S. pneumoniae serotypes in adults aged of 18 years and older, including healthy carriers and patients with acute otitis media (AOM), community-acquired pneumonia (CAP) and invasive pneumococcal infection (IPI). Materials and Methods. A total of 230 isolates of S. pneumoniae from 10 centers were included in the study from 01.06.2019 to 01.10.2019. Re-identification and typing using real-time PCR with 22 primer pairs were performed in the central laboratory (Institute of Antimicrobial Chemotherapy, Russia). Results. In healthy nasopharyngeal carriers (n = 31), the following serotypes of S. pneumoniae were detected: 19F (29.0%), 6А/В (22.6%), 3 (16.1%), 11A/D and 23F (9.7% each), 23A (6.4%), 14 and 15A/F (3.2% each); PCV-13 and PPV-23 covered 80.6% and 90.3% of those serotypes, respectively. In patients with AOM (n = 18), serotypes were: 3 (16.7%), 11A/D and 6A/B (11.1%, each), 16, 19А, 19F, 23F, 7A/F (5.55%, each); PCV-13 and PPV-23 covered 50% and 61.1% of those serotypes, respectively. Among 166 isolates from patients with CAP, the following serotypes were detected: 3 (12.0%), 19F and 6A/B (10.2%, each), 14 and 11A/D (5.4% each), 15A/F and 23A (4.8% each), 9N/L (4.2%), 18 and 22A/F (2.4% each), 19A and 23F (1.8% each), 16, 9V/A (1.2% each), 4 and 33A/33F/37 (0.6% each), non-vaccine serotypes (30.3%); PCV-13 and PPV-23 covered 45.6% and 57.0% of those serotypes, respectively. Isolates from patients with IPI (n=15) belonged to the following serotypes: 3 (26.7%), 12F, 23F and 9N/L (13.3% each), serotypes 4 and 15A/F (6.7%), non-vaccine serotype – 1 isolate (6.7%); PCV-13 and PPV-23 covered 46.7% and 73.3% of those serotypes, respectively. Conclusions. The majority of S. pneumoniae serotypes in adult population in Russia are included in PPV-23, but not in PCV-13 (primarily due to serotype 11A/D). There was a high PCV-13 and PPV-23 coverage of serotypes from healthy nasopharyngeal carriers. PPV-23 covered more than 60% of clinical isolates, whereas PCV-13 covered less than 60% (AOM – 50.0%, CAP – 45.6%, IPI – 46.7%), thus indicating a potentially lower efficacy of PCV-13 in adult population.
