Pneumococcal infection is one of the main causes of acute respiratory diseases and exacerbation of chronic ones. In order to study the prevalence of community-acquired pneumonia, the etiologic role of S. pneumoniaе and effectiveness of vaccination among children under the age of 6 in the town of industrial cities, we conducted a non-interventional epidemiologic study of serotypes of circulating pneumococci and their compliance with the declared composition of vaccines recommended for prevention of pneumococcal infection in children. We also studied incidence rates of community-acquired pneumonias among children under the age of five vaccinated against pneumococcal infection, depending on the schedule and beginning of immunization. Our findings indicate a significant role of pneumococcus in the etiology of community-acquired pneumonias among children under the age of 17 (24.14%).The established spectrum of serotypes of pneumococcus from nasopharyngial swabs in children under the age of 17 with community-acquired pneumonia in the town of this city showed that such serotypes as 19F, 14, 9V/A, 15A/F, 6A/B/C, 3, and 23F contributed the most to the development of pneumonia (79.97%). Pneumococcus serotypes found corresponded to the composition of PCV13 in 76.36% of cases and to that of PCV10 – in 67.27%. Proven the effectiveness of the vaccine, the rate of epidemiologic effectiveness was 48.7% in relation to pneumonia of any etiology. Shown the largest epidemiological effectiveness (54.8%) of vaccination in children vaccinated in an early period (under the age of 1).

Annual Dynamic

The research objective was to study prevalence of pneumococcal nasopharyngeal carriage among different age-group populations as well as evaluate annual dynamics of nasopharyngeal carriage levels against incidence rates of community-acquired pneumonia in Khabarovsk city in 2015. The bacteriological research was conducted among 2429 people (1100 adults and 1329 children) suffering from respiratory diseases. The level of pneumococcal carriage of the whole group was equal to 12.3±0.67%. The pneumococcal carriage was registered in all age-groups; its highest levels were diagnosed in children from 1 to 3 years old and in children from 3 to 6 years old (27.0±2.16 and 23.1±1.97%, respectively). The incidence rates of community-acquired pneumonia equaled to 290.2 per 100000 of general population and 687.1 per 100000 of children population. The comparative analysis of annual dynamics of pneumococcal carriage and community-acquired pneumonia incidence rates among general population of Khabarovsk city and separately for children from 0 to 14 years old has shown a correlation between these epidemiologic manifestations. Typically, pneumococcal carriage and incidence rates are the lowest in August; they elevate in September due to influence of common factors that are associated with “mixing” of people. The peculiarity of annual dynamic of community-acquired pneumonia incidence rates is a double-wave course with maximum in April and September. The revealed trends show the correlation between epidemic process of community-acquired pneumonia and undetected epidemic process of pneumococcal infections manifested as pneumococcal carriage.

Purpose of the Study: Assessment of the influence of the type of the adapted infant milk formula in infants on the formation of the body resistance. Children Characteristics and Study Methods. 105 virtually healthy children were examined, as follows: 35 children were breastfed (control group), 70 children were formula fed including 35 children that received NENNY with prebiotics formula based on the goat milk (main group), 35 children – formulas based on the cow milk with probiotics and prebiotics (comparison group). The incidence rate of the acute respiratory diseases (ARD) as well as the number of the pneumonia histories in the infants were assessed, and the body resistance index was calculated. The laboratory assessment of the child body immunoresistance was carried out using the method of imprint smears from the nasal mucous membranes and the method of nasal washes. Results. It was determined that there were 2 times more children of the main group with no history of the acute respiratory diseases when infant than in the comparison group. In general, the good resistance (were sick 0-3 times a year) in the main group was registered in 82.9% of the children, while it was only 60% in the comparison group. The average number of the ARD cases per year was 2.3 ± 0.02 in the main group, which is 1.5 times less than in the comparison group – 3.6 ± 0.04 (p <0.05), and in 1, 3 times more than that in the control group – 1.8 + 0.03 (p<0.05). In average, the resistance index was 0.28 ± 0.02 in the main group, while it was 0.36 ± 0.03 in the comparison group, and 0.25 ± 0.02 in the control group. When studying the incidence rate of the community-acquired pneumonia in the infants, it was revealed that 2.8% of them were ill in the control group, 5.7% of them in the main group, and 8.5% in the comparison group. When feeding the child with formulas based on the goat’s milk, the level of mucosal immunity of the nasal mucosa and enzyme systems of the intraleukocyte microbicidal system is assured, which is virtually indistinguishable from the level of immunity achieved with breastfeeding. Conclusion. Adapted NENNY with prebiotics formulas can be recommended for children who are formula fed when infant in order to increase the body’s resistance and to reduce the incidence rate of the acute respiratory diseases and community-acquired pneumonia.

According to WHO, acute respiratory diseases are at the forefront of the incidence rate of infants and are among the most common diseases due to which children are hospitalized. The aim of the research was to analyze the structure of morbidity and features of the course in acute respiratory diseases in infants with the study of the frequency of leading nosological forms that required inpatient treatment. A retrospective analysis of the medical records of inpatients (3845 children), treated during 2016-2018 was conducted. The study found that there is a tendency for an increase in the number of infants who require inpatient treatment, as well as an increased number of nosologies in the treated children. As the underlying disease, the first place in the structure of the morbidity belonged to acute respiratory viral infections. In the dynamics of the studied years, an increase in the frequency of acute obstructive bronchitis was noted. This pathology has the second place in the structure of morbidity among hospitalized children. The permanent third place in the structure of nosologies belongs to acute pneumonia. The premorbid background of most children with bronchial obstruction syndrome and acute community-acquired pneumonia was aggravated. The most commonly determined disorders were I-II degree anemia, overweight, impaired calcium metabolism, aggravated allergic history, transient immune deficiency. Conclusions. Our analysis of the structure of acute respiratory pathology in infants who required inpatient treatment showed that in the dynamics of 2016-2018, there was an increase in cases of acute obstructive bronchitis and acute community-acquired pneumonia. The study of general structure of nosologies in children treated at the inpatient department revealed an increase in their number and a tendency for the formation of comorbid pathology in infants.

В статье рассматриваются заболевания, зависящие от уровня витамина D в организме, возможные методы коррекции его уровня и их последствия. Рассматривается зависимость организма -как единого целого от уровня данного витамина в крови. На данный момент во всем мире наблюдается глобальный дефицит витамина D, у всех пациентов, которые сдают данный анализ, которое так же было выявлено на фоне глобальной пандемии “COVID-19”. Влияние витамина D на иммунитет абсолютно точно доказано, и поэтому его дефицитное состояние может ухудшать течение различных заболеваний. Также витамин D выступает в качестве гормона, недостаток которого приводит к патологиям сердечно-сосудистой системы, рахиту, остеопорозу, сахарному диабету, ожирению и другим серьезным заболеваниям. Неоднократно рассматривалось влияние его уровня на постоперационное восстановление. В статье так же приводятся методы коррекции посредством UV в зимнее время, которое как показали данные является опасной. В статье описываются нейродегенеративные расстройства, на которых оказывает огромное влияние уровень данного витамина и его профилактика. Проанализировано влияние его уровня на здоровье пациенток в постменопаузе, приводящее к нежелательным последствиям в том числе и остеопорозу. Приведены примеры влияния на защитные свойства ротовой полости при пародонте и кариесе. Описывается влияние на процесс течения острых респираторных заболеваний у детей, а также влияние на течение болезни при сахарном диабете. The article discusses diseases that depend on the level of vitamin D in the body, possible methods of correcting its level and their consequences. The dependence of the body on the level of this vitamin in the blood is considered. At the moment, there is a global vitamin D deficiency worldwide, which was revealed during the global COVID-19 pandemic. The positive effect of vitamin D on the immune system has been proven, and therefore its deficiency can worsen the course of various diseases. Vitamin D also acts as a hormone, the lack of which leads to pathologies of the cardiovascular system, rickets, osteoporosis, diabetes, obesity, and other serious diseases. The influence of its level on postoperative recovery is also considered. In addition, the article provides methods of correction by means of UV treatment in winter, which, as the data has shown, is dangerous. The article describes neurodegenerative disorders, which are greatly influenced by the level of this vitamin and its prevention. The influence of its level on the health of postmenopausal patients, leading to undesirable consequences, including osteoporosis, is analyzed. Examples of the effect on the protective properties of the oral cavity in periodontal disease and caries are given. The article describes the effect on the course of acute respiratory diseases in children, as well as the effect on the course of the disease in diabetes mellitus.

Background. Pneumococcal infection being one of the dominant causes of acute respiratory diseases and exacerbation of chronic ones is a serious problem for human health and society. The flood in the Amur river basin in the summer of 2013 created a special zone and risk conditions for the formation of respiratory pathology in the Far-Eastern region of Russia. We aimed to give clinical and epidemiological assessment of the effectiveness of vaccination programs of respiratory viral and pneumococcal infections and generalization of regional experience in the organization of a set of measures aimed at their prevention in the postflood period in the Far-Eastern region. Methods. The monitoring program includes children aged 2 to 5 years in the amount of 4988 with risk factors for pneumococcal infection. The pneumococcal conjugate vaccine Prevenar-13 was used for immunization. Data on the incidence of ARVI and pneumonia in children in pre- and postvaccination periods were to be recorded. The indicators and special criteria were used to assess the effectiveness of vaccination. To study the circulation of serovariants of pneumococcus in inflammatory diseases of the respiratory tract and nasopharyngeal carrier, bacteriological and molecular genetic methods (RT-PCR in the mode of multiprime detection) were used. Results. Differences in the frequency and range of serovariants of circulating isolates of pneumococcus in the postvaccinal period and in unvaccinated children, elimination of a number of serotypes, and appearance of circulation of nonvaccinated strains were revealed. The incidence of acute respiratory diseases and pneumonia among the vaccinated population for 2 years in the region decreased by 2.5 times. The coefficient of effectiveness of vaccination according to the indicator of morbidity of children with pneumonia reaches 75-100% with direct dependence on the age of children (r=0.98). Conclusion. Comparative statistical analysis revealed a high degree of effectiveness of regional programs with the methods of immunoprophylaxis of pneumococcal infections.

We describe here the results of respiratory syncytial virus (RSV) detection by reverse transcription polymerase chain reaction (RT-PCR) during two consecutive seasons, from December 2006 to February 2007 and from October 2007 to March 2008, performed in the National Laboratory of Influenza and Acute Respiratory Diseases, Bulgaria. A total number of 278 nasopharyngeal samples obtained from hospitalised children up to the age of five years were investigated for these two seasons. During the first season, the aetiological role of RSV was confirmed in 56 of 148 samples (37.8%) compared to 11 of 130 samples (8.5%) during the second season. Since the beginning of January 2008, RT-PCR for the detection of the recently identified human metapneumovirus (HMPV) has also been introduced in Bulgaria. This virus has been demonstrated as the aetiological agent in 13 out of 81 samples (16%) from children of the same age group. The use of RT-PCR allows the detection of a broader spectrum of viruses causing respiratory diseases, as well as better discrimination of the aetiological agents in clinically similar cases.
