Early recognition of children at risk of serious illness is essential in preventing morbidity and mortality, particularly in low- and middle-income countries (LMICs). This study aimed to validate the Emergency Department-Paediatric Early Warning Score (ED-PEWS) for use in acute care settings in LMICs. This observational study is based on previously...

Following an increase in notifiable invasive group A streptococcal (iGAS) infections in the Netherlands, we conducted a survey among 7 hospitals. Pediatric iGAS case numbers were 2-fold higher between July 2021 and June 2022 versus pre-COVID-19. A sharp increase occurred early 2022, most pronounced in <5 years old and for diagnoses empyema and necr...

Based on a survey sent to seven Dutch hospitals, we observed an substantial increase in invasive group A streptococcal infections in children in the Netherlands, comparing the pre-COVID-19 pandemic cohort of 2018-2019 to 2021-2022. The most affected age group were children between 0-5 years. Main diagnosis was pneumonia with empyema. Necrotizing fa...

We validated an adapted form of the Pediatric Sepsis Score (aPSS), a disease-specific severity score available within 60 min of PICU admission, in children with invasive infection. aPSS consist of all components of PSS except lactate. aPSS predicted mortality in children with invasive infection ( n = 4096; AUC 0.70 (95% CI 0.67–0.73)) and in childr...

Group A streptococcal (GAS) disease shows increasing incidence worldwide. We characterised children admitted with GAS infection to European hospitals and studied risk factors for severity and disability. This is a prospective, multicentre, cohort study (embedded in EUCLIDS and the Swiss Pediatric Sepsis Study) including 320 children, aged 1 month t...

Background: Coronavirus disease (COVID-19) infection during pregnancy could damage the placenta, but data on neonates born to COVID-19-positive mothers is scarce. In this case series, we aim to describe clinical characteristics, transmission rate and outcomes at 3 months of age among neonates born to mothers with COVID-19 diagnosed near the time o...

Purpose: Group A streptococcal (GAS) disease shows increasing incidence worldwide. We characterised children admitted with GAS infection to European hospitals and studied risk factors for severity and disability. Methods: Prospective, multicenter, cohort study (embedded in EUCLIDS and the Swiss Pediatric Sepsis Study) including 320 children, aged 1...

Objectives: We aimed to describe the variation of hemostasis proteins in children with bacterial infections due to different pathogens (Neisseria meningitidis, Streptococcus pneumoniae, Staphylococcus aureus, and group A streptococcus [GAS]) and to study hemostasis proteins in relation to mortality. Design: Preplanned analysis in prospective coh...

Background Pediatric osteoarticular infections (POAIs) are serious diseases requiring early diagnosis and treatment. Methods In this prospective multicenter cohort study, children with POAIs were selected from the European Union Childhood Life-threatening Infectious Diseases Study (EUCLIDS) database to analyze their demographic, clinical, and micr...

IMPORTANCE:. A Disintegrin and Metalloproteinase with Thrombospondin Motifs-1 is hypothesized to play a role in the pathogenesis of invasive infection, but studies in sepsis are lacking. OBJECTIVES:. To study A Disintegrin and Metalloproteinase with Thrombospondin Motifs-1 protein level in pediatric sepsis and to study the association with outcome....

We report a 5 months old boy who was admitted to the PICU because of fluctuating level of consciousness. An extensive workup in search for infectious, neurologic, toxicologic and metabolic etiologies was done. Although abdominal symptoms were absent, he eventually was diagnosed with intussusception which needed surgery to recover. Intussusception s...

Meningococcemia is notorious for evasion of the host immune system and its rapid progression to fulminant disease, and serves as a unique model for pediatric sepsis. Illness severity is determined by complex interplays among host, pathogen, and environment. The inflammatory host response, including proinflammatory and anti-inflammatory responses in...

Background The limited availability of microbiology services in sub-Saharan Africa impedes accurate diagnosis of bacterial pathogens and understanding of trends in prevalence and antibiotic sensitivities. We aimed to characterize bacteremia amongst hospitalized children in The Gambia and to identify factors associated with bacteremia and mortality....

Reduced target attainment of β-lactam antibiotics is reported in critically ill patients. However, as target attainment of cefotaxime in severely ill pediatric sepsis patients may differ from adults due to age-related variation in pharmacokinetics, we aimed to assess target attainment of cefotaxime in this pilot study using meningococcal septic sho...

Background: The complement system is a central component of the innate immune system. Constitutive biosynthesis of complement proteins is essential for homeostasis. Dysregulation as a consequence of genetic or environmental cues can lead to inflammatory syndromes or increased susceptibility to infection. However, very little is known about steady...

Background: Sepsis is one of the main reasons for non-elective admission to pediatric intensive care units (PICUs), but little is known about determinants influencing outcome. We characterized children admitted with community-acquired sepsis to European PICUs and studied risk factors for mortality and disability. Methods: Data were collected wit...

Background: Recent attempts to translate Sepsis-3 criteria to children have been restricted to PICU patients and did not target children in emergency departments (ED). We assessed the prognostic accuracy of the age-adjusted quick Sequential Organ Failure Assessment score (qSOFA) and compared the performance to SIRS and the quick Pediatric Logistic...

Pediatric meningococcal sepsis often results in morbidity and/or death, especially in young children. Our understanding of the reasons why young children are more susceptible to both the meningococcal infection itself and a more fulminant course of the disease is limited. Immunoglobulin G (IgG) is involved in the adaptive immune response against me...

Background: Sepsis and severe focal infections represent a substantial disease burden in children admitted to hospital. We aimed to understand the burden of disease and outcomes in children with life-threatening bacterial infections in Europe. Methods: The European Union Childhood Life-threatening Infectious Disease Study (EUCLIDS) was a prospec...

Background: To longitudinally study blood monocyte subset distribution and human leukocyte antigen-DR (HLA-DR) expression on monocyte subsets in children with sepsis, post-surgery, and trauma in relation to nosocomial infections and mortality. Methods: In 37 healthy children and 37 critically ill children (12 sepsis, 11 post-surgery, 10 trauma,...

Objectives: Children with meningococcal sepsis are highly at risk for fulminant disease, multiple organ failure, and death. Recently, neutrophil extracellular traps levels have been indicated as a marker for severity in different kinds of sepsis. Our aim was to study the role of neutrophil extracellular traposis in meninogococcal sepsis in childre...

The host response to infection involves complex interplays between inflammation, coagulation, and fibrinolysis. Deregulation of hemostasis and fibrinolysis are major causes of critical illness and important determinants of outcome in severe sepsis. The hemostatic responses to infection vary widely between individuals, and are in part explained by p...

Objective: To study whether the circadian variation of plasminogen-activator-inhibitor-1 (PAI-1) levels, with high morning levels, is associated with poor outcome of children with meningococcal sepsis presenting in the morning hours. Design: Retrospective analysis of prospectively collected clinical and laboratory data. Setting: Single center...
