pediatricians, especially in the differentiation with non-COVID-19 COVID-19 Pediatric Pneumonias: A pneumonia in the peak season of pneumonia. We aimed to compare the clinical Multicenter Cross-Sectional Study. characteristics of pediatric patients with COVID-19 and other respiratory pathogens Front. Cell. Infect. Microbiol. 11:663884. doi: 10.3389/fcimb.2021.663884 infected pneumonias. Frontiers in Cellular and Infection Microbiology | www.frontiersin.org1 July 2021 | Volume 11 | Article 663884 Jia et al. COVID-19 and Other Pediatric Pneumonia Methods: We conducted a multi-center, cross-sectional study of pediatric inpatients in China. Based on pathogenic test results, pediatric patients were divided into three groups, including COVID-19 pneumonia group, Non-COVID-19 viral (NCV) pneumonia group and Non-viral (NV) pneumonia group. Their clinical characteristics were compared by Kruskal- Wallis H test or chi-square test. Results: A total of 636 pediatric pneumonia inpatients, among which 87 in COVID-19 group, 194 in NCV group, and 355 in NV group, were included in analysis. Compared with NCV and NV patients, COVID-19 patients were older (median age 6.33, IQR 2.00-12.00 years), and relatively fewer COVID-19 patients presented fever (63.2%), cough (60.9%), shortness of breath (1.1%), and abnormal pulmonary auscultation (18.4%). The results were verified by the comparison of COVID-19, respiratory syncytial virus (RSV) and influenza A (IFA) pneumonia patients. Approximately 42.5%, 44.8%, and 12.6% of the COVID-19 patients presented simply ground-glass opacity (GGO), simply consolidation, and the both changes on computed tomography (CT) scans, respectively; the proportions were similar as those in NCV and NV group (p>0.05). Only 47.1% of COVID-19 patients had both lungs pneumonia, which was significantly lower than that proportion of nearly 80% in the other two groups. COVID-19 patients presented lower proportions of increased white blood cell count (16.5%) and abnormal procalcitonin (PCT) (10.7%), and a higher proportion of decreased lymphocyte count (44.0%) compared with the other two groups. Conclusion: Majority clinical characteristics of pediatric COVID-19 pneumonia patients were milder than non-COVID-19 patients. However, lymphocytopenia remained a prominent feature of COVID-19 pediatric pneumonia. Keywords: COVID-19 pneumonia, viral pneumonia, non-viral pneumonia, pediatric patients, clinical characteristics INTRODUCTION milder symptoms and better prognosis (CDC COVID-19 Response Team, 2020; National Health Commission of the Since December 2019, cases of pneumonia with no clear etiology People’s Republic of China, 2020). Although most pediatric were reported in Wuhan, Hubei, China, which was known as the patients with COVID-19 had a good prognosis, severe or Coronavirus Disease 2019 (COVID-19) and the virus was named critical cases or even death cases were reported (Lu et al., as severe acute respiratory syndrome coronavirus 2 (SARS-CoV- 2020). Additionally, with the pandemic of COVID-19 in the 2) by the World Health Organization (WHO). It subsequently world, more and more pediatric cases were reported and it brings has spread rapidly to the whole world (Huang et al., 2020; Lu a new challenge for pediatricians. et al., 2020; Zhu et al., 2020 ). People of all ages are susceptible to Pneumonias are the major cause of death among infectious COVID-19. Children are paid more attention as a vulnerable diseases in children less than five years old in the world, killing group. Fortunately, compared with the adult patients, the approximately 800,000 children a year (Liu et al., 2016). In number of pediatric patients were lower and mostly with clinical, pediatricians usually diagnosed pneumonia according to clinical manifestations and (or) chest imaging exam. Yet, fever, cough with or without sputum, wheeze are common Abbreviations: COVID-19, Coronavirus Disease 2019; SARS-CoV-2, severe acute symptoms in most cases with pneumonia even if they had respiratory syndrome coronavirus 2; NCV, Non-COVID-19 viral; NV, Non-viral; different pathogens. Previous study of COVID-19 pneumonia GGO, ground-glass opacity; CT, computed tomography; WHO, World Health also reported that the common symptoms were fever, cough
