Patterns of presentations of children to emergency departments across Europe and the impact of the COVID-19 pandemic: retrospective observational multinational study.

BackgroundTo investigate the impact of the COVID-19 pandemic and infection prevention measures on children visiting emergency departments across Europe. MethodsRoutine health data were extracted retrospectively from electronic patient records of children aged <16 years, presenting to 38 emergency departments (ED) in 16 European countries for the period January 2018 - May 2020, using predefined and standardized data domains. Observed and predicted numbers of ED attendances were calculated for the period February 2020 to May 2020. Poisson models and incidence rate ratios (IRR) were used to compare age groups, diagnoses and outcomes. FindingsReductions in pediatric ED attendances, hospital admissions and high triage urgencies were seen in all participating sites. ED attendances were relatively higher in countries with lower SARS-CoV-2 prevalence (incidence rate ratio (IRR) 2{middle dot}62, 95% CI 2{middle dot}19 to 3{middle dot}13) and in children aged >12 months (12-<24 months IRR 0{middle dot}89, 95% CI 0{middle dot}86 to 0{middle dot}92; 2-<5years IRR 0{middle dot}84, 95% CI 0{middle dot}82 to 0{middle dot}87; 5-<12 years IRR 0{middle dot}74, 95% CI 0{middle dot}72 to 0{middle dot}76; 12-<16 years IRR 0{middle dot}74, 95% CI 0{middle dot}71 to 0{middle dot}77; vs. age <12 months as reference group). The impact on pediatric intensive care admissions (IRR 1{middle dot}30, 95% CI 1{middle dot}16 to 1{middle dot}45) was not as great as the impact on general admissions. Lower triage urgencies were reduced more than higher triage urgencies (urgent triage IRR 1{middle dot}10, 95% CI 1{middle dot}08 to 1{middle dot}12; emergent and very urgent triage IRR 1{middle dot}53, 95% CI 1{middle dot}49 to 1{middle dot}57; vs. non-urgent triage category). Reductions were highest and sustained throughout the study period for children with communicable infectious diseases. InterpretationReductions in ED attendances were seen across Europe during the first COVID-19 lockdown period. More severely ill children continued to attend hospital more frequently compared to those with minor injuries and illnesses, although absolute numbers fell.

Changes in RT-PCR-positive SARS-CoV-2 rates in adults and children according to the epidemic stages

AimTo describe the trends of RT-PCR positive SARS-CoV-2 rates in children and adults according to the time of COVID-19 epidemic. MethodsIn this prospective multicenter study involving 45 pediatric units, we collected the results of nasopharyngeal swabs in France from March 2, 2020 to April 26, 2020. ResultsDuring the study period, 52,588 RT-PCR tests for SARS-CoV-2 were performed, 6,490 in children and 46,098 in adults. The risk ratio of RT-PCR positive SARS-CoV-2 tests for adults compared to children was 3.5 (95% CI [3.2;3.9]) for the whole study period. These rates varied according to the time of the epidemic and were higher at the peak. The lower rates of positive test in children persisted during the surveillance period but varied according to the time in the epidemic. ConclusionThe rate of positive RT-PCR positive SARS-CoV-2 tests for children was always less than that for adults but vary according to the epidemic stage.

Outbreak of Kawasaki disease in children during COVID-19 pandemic: a prospective observational study in Paris, France

BackgroundAcute clinical manifestations of SARS-CoV-2 infection are less frequent and less severe in children than in adults. However, recent observations raised concerns about potential post-viral severe inflammatory reactions in children infected with SARS-CoV-2. MethodsWe describe an outbreak of cases of Kawasaki disease (KD) admitted between April 27 and May 7, 2020, in the general paediatrics department of a university hospital in Paris, France. All children prospectively underwent nasopharyngeal swabs for SARS-CoV-2 RT-PCR, SARS-CoV-2 IgG serology testing, and echocardiography. The number of admissions for KD during the study period was compared to that observed since January 1, 2018, based on discharge codes, using Poisson regression. ResultsA total of 17 children were admitted for KD over an 11-day period, in contrast with a mean of 1.0 case per 2-week period over 2018-2019 (Poisson incidence rate ratio: 13.2 [95% confidence interval: 7.3-24.1], p <0.001). Their median age was 7.5 (range, 3.7-16.6) years, and 59% of patients originated from sub-Saharan Africa or Caribbean islands. Eleven patients presented with KD shock syndrome (KDSS) requiring intensive care support, and 12 had myocarditis. All children had marked gastrointestinal symptoms at the early stage of illness and high levels of inflammatory markers. Fourteen patients (82%) had evidence of recent SARS-CoV-2 infection (positive RT-PCR 7/17, positive IgG antibody detection 14/16). All patients received immunoglobulins and some received corticosteroids (5/17). The clinical outcome was favourable in all patients. Moderate coronary artery dilations were detected in 5 cases (29%) during hospitalisation. ConclusionsThe ongoing outbreak of KD in the Paris might be related to SARS-CoV2, and shows an unusually high proportion of children with gastrointestinal involvement, KDSS and African ancestry.

Neonatal sepsis: within and beyond China / 中华医学杂志(英文版)

Sepsis remains a significant cause of neonatal morbidity and mortality in China. A better understanding of neonatal sepsis in China as compared with other industrialized and non-industrialized countries may help optimize neonatal health care both regionally and globally. Literature cited in this review was retrieved from PubMed using the keywords "neonatal sepsis," "early-onset (EOS)" and "late-onset (LOS)" in English, with the focus set on population-based studies. This review provides an updated summary regarding the epidemiology, pathogen profile, infectious work-up, and empirical treatment of neonatal sepsis within and beyond China. The incidence of neonatal EOS and the proportion of Group B Streptococcus (GBS) within pathogens causing EOS in China seem to differ from those in developed countries, possibly due to different population characteristics and intrapartum/postnatal health care strategies. Whether to adopt GBS screening and intrapartum antibiotic prophylaxis in China remains highly debatable. The pathogen profile of LOS in China was shown to be similar to other countries. However, viruses as potential pathogens of neonatal LOS have been underappreciated. Growing antimicrobial resistance in China reflects limitations in adapting antibiotic regimen to local microbial profile and timely cessation of treatment in non-proven bacterial infections. This review stresses that the local epidemiology of neonatal sepsis should be closely monitored in each institution. A prompt and adequate infectious work-up is critically important in diagnosing neonatal sepsis. Adequate and appropriate antibiotic strategies must be overemphasized to prevent the emergence of multi-resistant bacteria in China.
