Background: Respiratory viral and bacterial infections are one of the leading causes of hospitalization and death worldwide, particularly affecting children, the elderly, and immune compromised individuals. The detection of causative pathogens is crucial for understanding the epidemiology, prevention, management, and treatment of severe pneumonia. Molecular diagnostic methods provide high sensitivity and speed, enabling the simultaneous detection of viral and bacterial co-infections. Aim: Detection of single and combined viral and bacterial infections in hospitalized children with pneumonia using multiplex PCR. Materials and Methods: We conducted a cross-sectional study design involving 100 hospitalized participants at the National Center for Mothers, Newborns, and Women II. The study utilized questionnaires and laboratory analysis methods. Nasopharyngeal swabs were collected from the participants using a sterile swab and transported in a UTM transport medium (Jiangsu, China). After nucleic acid extraction using the STARMag 96 ProPrepC assay, the samples were analyzed with the Seeprep 32 automated analyzer (Seegene Inc., Korea). Real-time polymerase chain reaction (PCR) analysis was performed using the Allplex™ RV Master Assay and Allplex™ PneumoBacter Assay (Seegene Inc., Korea), with the CFX-96 system (BioRad Inc., USA). Results: The prevalence of viral infections in the study population was as follows: influenza type A 3% (n=3), influenza type B 3% (n=3), total influenza virus 14% (n=14), respiratory syncytial virus 18% (n=18), adenovirus 10% (n=10), rhinovirus 20% (n=20), and SARS-CoV-2 5% (n=5). No bacterial infections, such as B.parapertussis or L.pneumophila, were detected. However, bacterial infections identified included B.pertussis in 1% (n=1), C.pneumoniae in 2% (n=2), H.influenzae in 43% (n=43), M.pneumoniae in 52% (n=52), and S.pneumoniae in 45% (n=45). Of the 100 children in the study, 6% had influenza or influenza-like illness. Among these, 43% had the virus alone, and 14% had a viral co-infection. Bacterial infections were detected individually in 40% of cases, with co-infections in 46% of bacterial cases. Conclusion Metapneumovirus, B.parapertussis, and Legionella pneumophila were not detected in the study participants (0%). Among the viral infections, respiratory syncytial virus (18%, n=18) and rhinovirus (20%, n=20) had the highest prevalence. For bacterial infections, H.influenzae (43%, n=43), M.pneumoniae (52%, n=52), and S.pneumoniae (45%, n=45) were most commonly detected.

Early detection of bronchial asthma in children and establishment of a national continuous monitoring system Introduction: Bronchial asthma - a chronic inflammatory disease with recurrent allergic reactions characterized by increased sensitivity of the bronchi to various factors, swelling of the bronchial mucosa, excessive mucus secretion, and narrowing of the airways due to severe muscle contraction. Early detection of bronchial asthma in childhood, its prevalence, and the establishment of a continuous monitoring system to assess the effectiveness of follow-up treatment Materials and methods: It is mild in children, but is ready to be severe. If left untreated for a long time, the structure of the bronchi changes irreversibly and becomes ineffective. There are cases of death due to risk factors for irritability and asthma. In the first objective of the study, the National Center for Maternal and Child Health (NCMCH) Children's Counseling Polyclinic, Respiratory Pathology Department, and the Children's Department of the General Hospital of 21 aimags and 9 districts were used to determine the prevalence of Acute respiratory infections, implemented outpatient (2019-2021). Within the scope of objectives 2 and 3 of the study, a self-controlled case-control study model was used to assess the diagnosis of asthma in the case group based on the GINA-2018 guideline evaluation and clinical and laboratory tests based on the GINA protocol treatment. The parameters were taken, the pre-treatment parameters were recorded and compared in the control group, and the results were calculated. Results: When the prevalence was determined by the Acute respiratory infections level, there were 11 cases per 1,000 children. 80.8% of cases of asthma were caused by asthma 1-5 times a year, and the majority or 96.5% were aged 0-9 years. Allergies include plant (42.9%), food (25.4%), and pet (14.3%) allergies under the age of 4, all types of allergies between the ages of 5-14, and plant allergies 15-19 years, (9%), food (21.4%), pet (14.3%), environmental moisture and mold allergies (14.3%). Among the 89 children treated according to GINA guidelines, 64.0% used spices or allergenic foods, 13.5% used antibiotics, 6.7% used paracetamol, and 13.5% used other drugs. Children with asthma were assessed according to GINA guidelines and monitored and treated for 1 year (0.0001), the number of cases of asthma (p = 0.035) and the number of people receiving emergency care (p = 0.042) decreased statistically. There was a statistically significant difference of 2%, nocturnal cough decreased by 15.2%, and whooping cough decreased by 1.4%. Conclusions: The prevalence of asthma was 11 cases per 1,000 children. The main causes of allergies are plants, food and pets. The number of coughs, hospitalizations and emergency room visits decreased with GINA treatment.
