1Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children.Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao 2020World Journal of Pediatrics2020,16,3:56
2Respiratory Virus Multiplex RT-PCR Assay Sensitivities and Influence Factors in Hospitalized Children with Lower Respiratory Tract Infections显示文摘Multiplex RT-PCR assays have been widely used tools for detection and differentiation of a panel of respiratory viral pathogens. In this study, we evaluated the Qiagen ResPlex II V2.0 kit and explored factors influencing its sensitivity. Nasopharyngeal swab (NPS) specimens were prospectively collected from pediatric inpatients with lower respiratory tract infections at the time of admission in the Shenzhen Children's Hospital from May 2009 to April 2010. Total nucleic acids were extracted using the EZ1 system (Qiagen, Germany) and 17 respiratory viruses and genotypes including influenza A virus (FluA), FluB, parainfluenza virus 1 (PIV1), PIV2, PIV3, PIV4, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), rhinoviruses (RhV), enteroviruses (EnV), human bocaviruses (hBoV), adenoviruses (AdV), four coronaviruses (229E, OC43, NL63 and HKU1), and FluA 2009 pandemic H1N1(H1N1-p) were detected and identified by the ResPlex II kit. In parallel, 16 real-time TaqMan quantitative RT-PCR assays were used to quantitatively detect each virus except for RhV. Influenza and parainfluenza viral cultures were also performed. Among the total 438 NPS specimens collected during the study period, one or more viral pathogens were detected in 274 (62.6%) and 201(45.9%) specimens by monoplex TaqMan RT-PCR and multiplex ResPlex, respectively. When results from monoplex PCR or cell culture were used as the reference standard, the multiplex PCR possessed specificities of 92.9-100.0%. The sensitivity of multiplex PCR for PIV3, hMPV, PIV1 and BoV were 73.1%, 70%, 66.7% and 55.6%, respectively, while low sensitivities (11.1%-40.0%) were observed for FluA, EnV, OC43, RSV and H1N1. Among the seven viruses/genotypes detected with higher frequencies, multiplex PCR sensitivities were correlated significantly with viral loads determined by the TaqMan RT-PCR in FluA, H1N1-p and RSV (p=0.011-0.000). The Qiagen ResPlex II multiplex RT-PCR kit possesses excellent specificity for simultaneous detection of 17 viral pathogens in NPS specimens in pediatric inpatients at the time of admission. The sensitivity of multiplex RT-PCR was influenced by viral loads, specimen process methods, primer and probe design and amplification condition.Jikui Deng Zhuoya Ma Wenbo Huang Chengrong Li Heping Wang Yuejie Zheng Rong Zhou Yi-Wei Tang 2013Virologica Sinica2013,28,2:14
3Retrospective Study of an Adenovirus Pneumonia Outbreak in Shenzhen in 2017显示文摘Dear Editor,Human adenoviruses (HAd Vs) are associated with respiratory,gastrointestinal,ophthalmological,genitourinary,and neurological infections.To date,more than 100genotypes of HAd Vs have been identified.They are classified into seven species,A to G (HAd V Working Group,http://hadvwg.gmu.edu/).Zhiwei Lu Heping Wang Yanmin Bao Zhichuan Li Huan Zhang Haixia Zhao Yuejie Zheng 2021Virologica Sinica2021,36,3:4
4Severe acute respiratory syndrome coronavirus 2-induced multisystem inflammatory syndrome in children显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-induced multisystem inflammatory syndrome in children(MIS-C)is a life-threatening illness that has been reported in the United States and Europe.It affects multiple organ systems and often requires patient admission to an intensive care unit.Although some features of MIS-C overlap with Kawasaki disease,MIS-C is more common among older children and adolescents,more often affects cardiovascular and gastrointestinal systems,and more frequently presents with elevated inflammatory markers.Rapid and complete clinical recovery is possible in nearly all patients following immunomodulation therapy.Thus far,MIS-C pathophysiology and long-term prognosis are not sufficiently clear;further studies are needed.Zhiguan Feng Yanmin Bao Yonghong Yang Yuejie Zheng Kunling Shen 2020Pediatric Investigation2020,4,4:3
5Epidemiological characteristics and clinical manifestations of pediatric patients with COVID-19 in China: A multicenter retrospective study显示文摘Importance:The Coronavirus disease 2019(COVID-19)global pandemic poses a considerable challenge for pediatricians.Objective:This study aimed to identify the epidemiological characteristics and clinical features of pediatric patients with COVID-19 in China.Methods:This multicenter retrospective study included pediatric patients from 46 hospitals in China,covering 12 provinces and two municipalities.Epidemiological,demographic,clinical,laboratory,treatment,and outcome data were analyzed.Results:In total,211 pediatric patients with COVID-19 were included in this study.The median age was 7.0 years(range:22 days to 18 years).Approximately 16.3%of the patients exhibited asymptomatic infections,23.0%had upper respiratory tract infections,and 60.7%had pneumonia,including two with severe pneumonia and one with critical illness.Approximately 78.7%of the pediatric patients occurred in familial clusters.The most three common symptoms or signs at onset in children with COVID-19 were fever(54.5%),cough(49.3%),and pharyngeal congestion(20.8%).Only 17.6%of the patients presented with decreased lymphocyte count,whereas 13.6%had increased lymphocyte count.Among the patients with pneumonia who exhibited abnormal chest computed tomography findings,18.2%(23/127)of the patients had no other symptoms.Generally,the chest radiographs showed abnormalities that affected both lungs(49.6%);ground-glass opacity(47.2%)was the most common manifestation.The cure and improvement rates were 86.7%(183/211)and 13.3%(28/211),respectively.Only one patient with an underlying condition received invasive mechanical ventilation;none of the patients died.Interpretation:Similar to adults,children of all age groups are susceptible to COVID-19.Fortunately,most pediatric patients have mild symptoms or remain asymptomatic,despite the high incidence of pneumonia.Decreased proportions of white blood cells and lymphocytes are less frequent in children than in adults.Yan Bai Liwei Gao Xianfeng Wang Lili Zhong Jingfeng Li Shenggang Ding Yuejie Zheng Jun Liu Yuxia Cui Lina Wang Mingfeng Han Jun Liu Xinping Jiang Min Jiang Junhua Li Ning Chen Yunxiao Shang Hourong Zhou Yi Xu Gen Lu Xing Chen Jizhi Xu Qihong Fan Yu Tang Jiang Wu Cen Li Xiaoxiang Yang Chunxi Chen Yonghong Yang Gary Wing-Kin Wong Adong Shen Tianyou Wang Runming Jin Baoping Xu Kunling Shen 2021Pediatric Investigation2021,5,3:0
