RESUMEN
OBJECTIVES: Catheter removal is recommended in adults with Staphylococcus aureus central-line-associated bloodstream infection (CLABSI) but is controversial in children with long-term central venous catheters (LTCVC). We evaluated the occurrence of catheter salvage strategy (CSS) in children with S. aureus LTCVC-associated CLABSI and assessed determinants of CSS failure. METHODS: We retrospectively included children (<18 years) with an LTCVC and hospitalized with S. aureus CLABSI in eight French tertiary-care hospitals (2010-2018). CSS was defined as an LTCVC left in place ≥72 h after initiating empiric antibiotic treatment for suspected bacteraemia. Characteristics of patients were reviewed, and multi-variable logistic regression was performed to identify factors associated with CSS failure (i.e., persistence, recurrence or complications of bacteraemia). RESULTS: We included 273 episodes of S. aureus LTCVC-associated CLABSI. CSS was chosen in 194 out of 273 (71%) cases and failed in 74 of them (38%). The main type of CSS failure was the persistence of bacteraemia (39 of 74 cases, 53%). Factors independently associated with CSS failure were: history of catheter infection (adjusted odds ratio (aOR) 3.18, 95% confidence interval (CI) 1.38-7.36), CLABSI occurring on an implantable venous access device (aOR 7.61, 95% CI 1.98-29.20) when compared with tunnelled-cuffed CVC, polymicrobial CLABSI (aOR 3.45, 95% CI 1.25-9.50), and severe sepsis at the initial stage of infection (aOR 4.46, 95% CI 1.18-16.82). CONCLUSIONS: CSS was frequently chosen in children with S. aureus LTCVC-associated CLABSI, and failure occurred in one-third of cases. The identified risk factors may help clinicians identify children at risk for CSS failure.

Multisystem inflammatory syndrome in children (MIS-C) is a novel post-infectious disease occurring in the context of SARS-CoV2 infection. COVID-19 vaccines have been authorized since December 2020, and adverse events including myocarditis have been reported following vaccination. We describe the cases of two pediatric patients presenting with clinical and laboratory features suggestive of MIS-C a few days after receiving their first dose of the Pfizer BNT162b2 vaccine. The outcome was favorable for both patients (after corticosteroid and immunoglobulin administration for one patient). These cases suggest an association between the COVID-19 vaccine and the occurrence of MIS-C.

OBJECTIVES: The aim of this study was to describe severe forms of novel coronavirus disease 2019 in children, including patient characteristics, clinical, laboratory, and imaging findings, as well as the disease management and outcomes. METHODS: This was a retrospective, single-center, observational study conducted in a pediatric intensive and high-dependency care unit (PICU, HDU) in an urban hospital in Paris. All patients, aged from 1 month to 18 years, admitted for confirmed or highly suspected SARS-CoV-2 were included. RESULTS: We analyzed the data of 27 children. Comorbidities (n=19, 70%) were mainly neurological (n=7), respiratory, (n=4), or sickle cell disease (n=4). SARS-CoV-2 PCR results were positive in 24 children (nasopharyngeal swabs). The three remaining children had a chest CT scan consistent with COVID-19. Respiratory involvement was observed in 24 patients (89%). Supportive treatments were invasive mechanical ventilation (n=9), catecholamine (n=4), erythropheresis (n=4), renal replacement therapy (n=1), and extracorporeal membrane oxygenation (n=1). Five children died, of whom three were without past medical history. CONCLUSION: This study highlighted the large spectrum of clinical presentation and time course of disease progression as well as the non-negligible occurrence of pediatric life-threatening and fatal cases of COVID-19 mostly in patients with comorbidities. Additional laboratory investigations are needed to further analyze the mechanism underlying the variability of SARS-Cov-2 pathogenicity in children.
