Abstract Background: Acute respiratory tract infections (ARTIS) are the common diseases in children and common methods frequently fail to identify the infectious etiology especially for viruses. The Filmarray respiratory panel (FARP) can reliably and rapidly identify viruses and bacterial pathogens. This study is to evaluate the performance and clinical significance of FARP in children with ARTIS.Methods: A total of 90 nasopharyngeal secretion (NPS) samples from children with ARTIS were enrolled. The FARP assay for 17 pathogens and other common methods including direct fluorescence assay (DFA) were performed to analyze these samples. Clinical data of all patients was also collected and evaluated.Results: Among the 90 samples, 58 samples (64.4%) were positive for 13 pathogens by FARP and 18 positive samples were detected with multiple-virus (31.3%, 18/58). Human rhinovirus/ enterovirus (21.0%%, 17/58) were predominant pathogen, followed by adenovirus (18.5%). Higher proportions of various pathogens were identified in the infant and toddler (0–2 years) groups with human rhinovirus/enterovirus being mostly virus. Adenovirus were common in the group aged 3–5 years, but only three pathogens including M.pneumoniae, respiratory syncytial virus, and adenovirus were also found in age group (6-14 years). Among 58 FARP positive patients, significant differences were in antibiotic prescription and use of hormone the single-organism-positive group and the multi-organism-positive group (P<0.05). Furthermore, there was significant difference in use of anti-virus and usage of hormone between severe respiratory infections group and non severe respiratory infections group (P<0.05). Conclusions: This study demonstrated that FARP can provide the rapid detection of respiratory virus and atypical bacteria for children, especially with severe respiratory tract infections.

Abstract Background Respiratory tract infections (RTIs) are the common diseases in children and the routine detection methods frequently fail to identify the infectious pathogens especially for viruses. The Filmarray respiratory panel (FARP) can reliably and rapidly identify viruses and bacteria pathogens. This study is to evaluate the performance and clinical significance of FARP in children. Methods Children diagnosed with RTIs in pediatric intensive care unit (PICU) were enrolled in this study. Nasopharyngeal secretion (NPS) samples of these children were collected and the FARP assay for 17 pathogens and routine microbiological methods were performed. Clinical data of all patients was also collected and evaluated. Results A total of 90 children were enrolled into this study and 58 patients (64.4%) were positive for 13 pathogens by FARP, with 18 being detected positive with multiple-virus (31.3%, 18/58). Human rhinovirus/enterovirus (21.0%%, 17/58) were the predominant pathogen, followed by adenovirus (18.5%). Higher proportions of various pathogens were identified in the infant and toddler (0–2 years) groups with human rhinovirus/enterovirus being mostly virus. Adenovirus were common in the group aged 3–5 years, but only three pathogens including M.pneumoniae, respiratory syncytial virus, and adenovirus were also found in age group (6–14 years). Among 58 FARP positive patients, significant differences were found in antibiotic prescription and use of glucocorticoid between the single-organism-positive group and the multi-organism-positive group (P < 0.05). Furthermore, there was significant difference in use of anti-virus and usage of glucocorticoid between severe respiratory infections group and non severe respiratory infections group (P < 0.05). Conclusions This study demonstrated that FARP can provide the rapid detection of respiratory virus and atypical bacteria for children, especially with severe respiratory tract infections.

AbstractHuman respiratory syncytial virus (RSV) is a major cause of acute respiratory tract infections in children and immunocompromised adults worldwide. Here we report that amoebae-release respirable-sized vesicles containing high concentrations of infectious RSV that persisted for the duration of the experiment. Given the ubiquity of amoebae in moist environments, our results suggest that extracellular amoebal-vesicles could contribute to the environmental persistence of respiratory viruses, including potential resistance to disinfection processes and thereby offering novel pathways for viral dissemination and transmission.

Abstract Background Acute respiratory infections (ARIs) are among the leading causes of hospitalization in children. Understanding the local dominant viral etiologies is important to inform infection control practices and clinical management. This study aimed to investigate the viral etiology and epidemiology of respiratory infections among pediatric inpatients in Macao. Methods A retrospective study using electronic health records between 2014 and 2017 at Kiang Wu Hospital was performed. Nasopharyngeal swab specimens were obtained from hospitalized children aged 13 years or younger with respiratory tract diseases. xMAP multiplex assays were employed to detect respiratory agents including 10 respiratory viruses. Data were analyzed to describe the frequency and seasonality. Results Of the 4880 children enrolled in the study, 3767 (77.1%) were positive for at least one of the 13 viral pathogens tested, of which 2707 (55.5%) being male and 2635 (70.0%) under 2 years old. Among the positive results, there were 3091 (82.0%) single infections and 676 (18.0%) multiple infections. The predominant viruses included human rhinovirus/enterovirus (HRV/EV 27.4%), adenovirus (ADV, 15.8%), respiratory syncytial virus B (RSVB, 7.8%) and respiratory syncytial virus A (RSVA, 7.8%). The detection of viral infection was the most prevalent in autumn (960/1176, 81.6%), followed by spring (1095/1406, 77.9%), winter (768/992, 77.4%), and summer (944/1306, 72.3%), with HRV/EV and ADV being most commonly detected throughout the 4 years of study period. The detection rate of viral infection was highest among ARI patients presented with croup (123/141, 87.2%), followed by lower respiratory tract infection (1924/2356, 81.7%) and upper respiratory tract infection (1720/2383, 72.2%). FluA, FluB and ADV were positive factors for upper respiratory tract infections. On the other hand, infection with RSVA, RSVB, PIV3, PIV4, HMPV, and EV/RHV were positively associated with lower respiratory tract infections; and PIV1, PIV2, and PIV3 were positively associated with croup. Conclusions This is the first study in Macao to determine the viral etiology and epidemiology of pediatric patients hospitalized for ARIs. The study findings can contribute to the awareness of pathogen, appropriate preventative measure, accurate diagnosis, and proper clinical management of respiratory viral infections among children in Macao.

Abstract Background There is a lack of studies comparing PCT, CRP and WBC levels in the differential diagnosis of acute bacterial, viral, and mycoplasmal respiratory tract infections. It is necessary to explore the correlation between above markers and different types of ARTI. Methods 108 children with confirmed bacterial infection were regarded as group A, 116 children with virus infection were regarded as group B, and 122 children with mycoplasmal infection were regarded as group C. The levels of PCT, CRP and WBC of the three groups were detected and compared. Results The levels of PCT, CRP and WBC in group A were significantly higher than those in groups B and C (p < 0.05). The positive rate of combined detection of PCT, CRP and WBC was significant higher than that of single detection. There was no significant difference in PCT, CRP and WBC levels between the group of G+ bacterial infection and G− bacterial infection (p > 0.05). ROC curve results showed that the AUC of PCT, CRP and WBC for the diagnosis of bacterial respiratory infections were 0.65, 0.55, and 0.58, respectively. Conclusions PCT, CRP and WBC can be combined as effective indicators for the identification of acute bacterial or no-bacterial infections in children. The levels of PCT and CRP have higher differential diagnostic value than that of WBC in infection, and the combined examination of the three is more valuable in clinic.

Human coronavirus HKU1 (HCoV-HKU1) is a RNA virus which gets in the human cells by binding to the receptor of  N-acetyl-9-O-acetylneuraminic acid. Human Coronaviruses (HCoVs), including HCoV-HKU1, are globally found. HCoV-HKU1 is responsible for upper and lower respiratory tract infections, usually with mild symptoms. In severe cases, HCoV-HKU1 can cause life-threatening respiratory illness especially in vulnerable hosts such as elderly, children and immunocompromised patients. In Greece, Respiratory Syncytial Virus (RSV) and influenza are the most common viruses causing respiratory tract infections. Traditionally, HCoVs are responsible for less than 3% of respiratory infections in Greek population. HCoVs 229E and OC43 have been shown to circulate in Greece. We report the first case of lung infection in an immunocompromised woman due to HCoV-HKU1, that has never been before detected in Greece. HCoV-HKU1 is related to severe disease even in healthy individuals and must be considered in the differential diagnosis of severe respiratory infections.

Background: Overuse of antibiotics is a significant problem in low- and middle-income countries where recommended treatment guidelines are not routinely practiced, resulting in antimicrobial resistance. Acute respiratory tract infections, mostly viral in origin, remain the clinical category for most commonly prescribed antibiotics. Due to the lack of local evidence about antibiotic prescribing trends in such infections, this study was conducted to evaluate the prescribing patterns in general and antibiotic prescribing trends specifically in prescriptions with the diagnosis of acute respiratory infections in district Mirpur of Azad Kashmir. Patients and methods: A prospective cross-sectional study carried out in the Department of Pharmacology and Therapeutics, Army Medical College, Rawalpindi, and outpatient departments of public health facilities in district Mirpur, Kashmir, from Aug to Oct 2020. Data were collected from 10 different public health facilities in District Mirpur, Kashmir including, three rural health centers (RHC) and five basic health units (BHU). Prescribing pattern analysis by objective observations of the prescriptions after patient-physician encounter against the World Health Organization defined core prescribing indicators. The appropriateness of antibiotic use was analyzed against clinical practice guidelines. IBM SPSS Statistics for Windows, Version 26 was used for data analysis. Descriptive analysis was done to find frequencies and percentages for categorical data and means and standard deviation for continuous data. Results: Total number of prescriptions evaluated was 144. Number of prescriptions containing antibiotics was 118 (82%) (standard, 20 - 26.8%). Inappropriate use of antibiotics was seen in 78% of cases where no antibiotics were indicated. The average number of medicines per prescription was 3.11 (standard, 2.1), whereas 79% of medicines prescribed were from the national essential medicine list (standard, 100%). Only 2.5% (standard, 100%) of the medications were prescribed with generic names. Conclusion: This study shows an inappropriate and overuse of antibiotics for acute respiratory tract infections, indicating a lack of adherence to core prescribing indicators and clinical guidelines by the physicians in outpatient clinics of Mirpur.

Objective There is a lack of studies comparing Procalcitonin (PCT), C-reactive protein (CRP) and white blood cell (WBC) levels in the differential diagnosis of acute bacterial, viral, and mycoplasmal respiratory infections. It is necessary to explore the correlation between above markers and different types of acute respiratory tract infections (ARTI). Methods 108 children with confirmed bacterial infection were regarded as group A, 116 children with virus infection were regarded as group B, and 122 children with mycoplasma infection were regarded as group C. The levels of PCT, CRP and WBC of the three groups were detected and compared. Results The levels of PCT, CRP and WBC in group A were significantly higher than those in groups B and C (P <0.05). The positive rate of combined detection of PCT, CRP and WBC was significantly higher than that of single detection. There was no significant difference of PCT, CRP and WBC levels between the group of Gram-positive (G+) bacteria infection and Gram-negative (G-) bacteria infection (P >0.05). ROC curve results showed that the area under the curve (AUC) of PCT, CRP and WBC for the diagnosis of bacterial respiratory infections were 0.65, 0.55, and 0.58, respectively. Conclusions PCT, CRP and WBC can be used as effective indicators for the identification of acute bacterial or no-bacterial infections in children. The levels of PCT and CRP have higher differential diagnostic value than that of WBC in infection, and the combined examination of the three is more valuable in clinic.
