Objective. To determine the epidemiology and therapeutic management of patients with severe acute bronchiolitis (AB) admitted to paediatric intensive care units (PICUs) in Spain. Design. Descriptive, prospective, multicentre study. Setting. Sixteen Spanish PICUs. Patients. Patients with severe AB who required admission to any of the participating PICUs over 1 year. Interventions. Both epidemiological variables and medical treatment received were recorded. Results. A total of 262 patients were recruited; 143 were male (54.6%), with median age of 1 month (0–23). Median stay in the PICU was 7 days (1–46). Sixty patients (23%) received no nebuliser treatment, while the rest received a combination of inhalation therapies. One-quarter of patients (24.8%) received corticosteroids and 56.5% antibiotic therapy. High-flow oxygen therapy was used in 14.3% and noninvasive ventilation (NIV) was used in 75.6%. Endotracheal intubation was required in 24.4% of patients. Younger age, antibiotic therapy, and invasive mechanical ventilation (IMV) were risk factors that significantly increased the stay in the PICU. Conclusions. Spanish PICUs continue to routinely use nebulised bronchodilator treatment and corticosteroid therapy. Despite NIV being widely used in this condition, intubation was required in one-quarter of cases. Younger age, antibiotic therapy, and IMV were associated with a longer stay in the PICU.

Objectives: Increasing evidence supports the association of fluid overload with adverse outcomes in different diseases. To our knowledge, few studies have examined the impact of fluid balance on clinical outcome in severe bronchiolitis. Our aim was to determine whether fluid overload was associated with adverse clinical outcomes in critically ill children with severe bronchiolitis. Design: Descriptive, prospective, multicenter study. Setting: Sixteen Spanish PICUs. Patients: Severe acute bronchiolitis who required admission from October 2014 to May 2015 were included. Interventions: None. Measurements and Main Results: Total fluid intake and output were prospectively recorded during PICU assistance. Fluid balance was measured at 24, 48, and 72 hours after PICU admission. A total of 262 patients were enrolled; 54.6% were male. Median age was 1 month (interquartile range, 1–3 mo). Patients had a positive fluid balance during the first 4 days of PICU admission, reaching a neutral balance on day 4. A positive balance at 24 hours in patients admitted to the PICU with severe bronchiolitis was related with longer stay in PICU (p < 0.001), longer hospital stay (p < 0.001), longer duration of mechanical ventilation (p = 0.016), and longer duration of noninvasive ventilation (p = 0.0029). Conclusions: Critically ill patients with severe acute bronchiolitis who present a positive balance in the first 24 hours of PICU admission have poorer clinical outcomes with longer PICU and hospital length of stay and duration of invasive and noninvasive mechanical ventilation.

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 to 18 years, admitted with GAS infection to 41 hospitals in 6 European countries from 2012 to 2016. Demographic, clinical, microbiological and outcome data were collected. A total of 195 (61%) patients had sepsis. Two hundred thirty-six (74%) patients had GAS detected from a normally sterile site. The most common infection sites were the lower respiratory tract (LRTI) (22%), skin and soft tissue (SSTI) (23%) and bone and joint (19%). Compared to patients not admitted to PICU, patients admitted to PICU more commonly had LRTI (39 vs 8%), infection without a focus (22 vs 8%) and intracranial infection (9 vs 3%); less commonly had SSTI and bone and joint infections ( p < 0.001); and were younger (median 40 (IQR 21–83) vs 56 (IQR 36–85) months, p = 0.01). Six PICU patients (2%) died. Sequelae at discharge from hospital were largely limited to patients admitted to PICU (29 vs 3%, p < 0.001; 12% overall) and included neurodisability, amputation, skin grafts, hearing loss and need for surgery. More patients were recruited in winter and spring ( p < 0.001). Conclusion : In an era of observed marked reduction in vaccine-preventable infections, GAS infection requiring hospital admission is still associated with significant severe disease in younger children, and short- and long-term morbidity. Further advances are required in the prevention and early recognition of GAS disease. What is Known: • Despite temporal and geographical variability, there is an increase of incidence of infection with group A streptococci. However, data on the epidemiology of group A streptococcal infections in European children is limited. What is New: • In a large, prospective cohort of children with community-acquired bacterial infection requiring hospitalisation in Europe, GAS was the most frequent pathogen, with 12% disability at discharge, and 2% mortality in patients with GAS infection. • In children with GAS sepsis, IVIG was used in only 4.6% of patients and clindamycin in 29% of patients.
