Pneumococcal carriage in children with COVID-19

Background: SARS-CoV-2 is the new virus, and Streptococcus pneumoniae is one of the most important pathogens affecting humans. However, we do not yet know whether these microorganisms interact. Thus, we aimed to evaluate the relationship between Streptococcus pneumoniae and SARS-CoV-2 in pediatric patients. Methods: This study was conducted retrospectively by means of medical records of pediatric patients who were tested for SARS-CoV-2 between March 11 and June 04, 2020, in the University of Health Sciences, Ankara Educating and Training Hospital and Hacettepe University Faculty of Medicine. Results: We evaluated 829 pediatric patients for S. pneumoniae and SARS-CoV-2 from their nasopharyngeal specimen. Of 115 children positive for SARS-CoV-2, 32.2% had a positive S. pneumoniae test, whereas of 714 children negative for SARS-CoV-2, 14.1% had a positive S. pneumoniae test (p < .01). We compared patients with positive vs. negative SARS-CoV-2 tests according to S. pneumoniae positivity There were no statistically significant differences in terms of gender, underlying disease, fever, cough, leukocytosis, lymphopenia, increased CRP, increased procalcitonin, findings of chest x-ray, severity of disease, and treatment. Conclusion: The nasopharyngeal S. pneumoniae carriage rate in patients with COVID-19 was higher than in non-infected children, while S. pneumoniae carriage did not affect the course of COVID-19 disease. Pneumococcal vaccination is significant, such that we do not know the outcomes of increased pneumococcal carriage for the upcoming months of pandemic

Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)

Background: Febrile seizure is the most common childhood neurological disorder, is an important health problem with potential short- and long-term complications, also leading to economic burden and increased parental anxiety about fevers and seizures occurring in their children. There are no routine recommendation to detect etiological causes of FS for neurological perspective, further knowledge about the etiological causes of FS in children will support preventive measures and follow-up strategies. The aim of this study is to evaluate the percentage of respiratory viruses in children with FS. Methods: This prospective multicenter study, entitled "Viral etiological causes of febrile seizures for respiratory pathogens (EFES Study)" examined representative populations in eight different cities in Turkey between March 1, 2016 and April 1, 2017. Nasopharyngeal swabs were taken from all children at presentation. A respiratory multiplex array was performed to detect for influenza A and B; respiratory syncytial virus A and B; human parainfluenza virus 1-2-3 and 4; human coronavirus 229E and OC43; human rhinovirus; human enterovirus; human adenovirus; human bocavirus; human metapneumovirus. Results: During the study period, at least one virus was detected in 82.7% (144/174) of children with FS. The most frequently detected virus was adenovirus, followed by influenza A and influenza B. Detection of more than one virus was present in 58.3% of the children with FS, and the most common co-existence was the presence of adenovirus and influenza B. In children younger than 12 months, Coronavirus OC43 was the most common, while influenza A was most frequently observed in children older than 48 months (p ). Human bocavirus was common in children who experienced complex FS, while respiratory syncytial virus (RSV) A was more common in children who experienced simple FS. Influenza B virus was the most common virus identified in children who were experiencing their first incidence of FS (p ). Conclusions: This study indicates that respiratory viruses are important in the etiology of FS in children. The results show that antibiotics must be prescribed carefully in children with FS since the majority of cases are related to viral causes. Widespread use of the existing quadrivalent influenza vaccine might be useful for the prevention of FS related to the flu. Further vaccine candidates for potential respiratory pathogens, including RSV, might be helpful for the prevention of FS
