Stridor is a clinical sign of an underlying disease and a common reason for pediatric emergency department (PED) consultation. Patients presenting with stridor must be evaluated to determine the origin of this abnormality. We present the case of a 7-year-old female patient who presented to our Pediatric Emergency Department with a history of recurrent episodes of stridor with increasing frequency over the previous 4 years, for this reason she was previously admitted to the pediatric intensive care unit. Findings from the otorhinolaryngologic assessment with flexible fiber-optic endoscopy led to a diagnosis of congenital synechia of the vocal cords. The cervical CT scan evidenced critical stenosis of the airway. An initial cordectomy and placement of a silicone device for fixation were performed. Subsequently, the patient required 6 additional interventions for progressive dilation of the glottic space at the level of the vocal cords and injections of mitomycin C injections (an antineoplastic that inhibits collagen proliferation). This case highlights the importance of additional studies (especially examination of the upper airway) when atypical or recurrent findings are revealed by the clinical history, physical examination, or disease course in patients with croup to prioritize cases severe enough to require pediatric intensive care unit admission.

BACKGROUND: Asthma is a common cause of admission to the pediatric intensive care unit (PICU). We described and analyzed the therapies applied to children admitted to a tertiary PICU because of asthma. Later, we evaluated high-flow nasal cannula (HFNC) use in these patients and compared their evolution and complications with those who received non-invasive ventilation. METHODS: We conducted a prospective observational study (October 2017-October 2019). Collected data: epidemiological, clinical, respiratory support therapy needed, complementary tests, and PICU and hospital stay. Patients were divided into three groups: (1) only HFNC; (2) HFNC and non-invasive mechanical ventilation (NIMV); and (3) only NIMV. RESULTS: Seventy-six patients were included (39 female). The median age was 2 years and 1 month. The median pulmonary score was 5. The median PICU stay was 3 days, and the hospital stay was 6 days. Children with HNFC only (56/76) had fewer PICU days (p = 0.025) and did not require NIMV (6/76). Children with HFNC had a higher oxygen saturation/fraction of inspired oxygen ratio ratio (p = 0.025) and lower PCO2 (p = 0.032). In the group receiving both therapies (14/76), NIMV was used first in all cases. No epidemiologic or clinical differences were found among groups. CONCLUSION: HFNC was a safe approach that did not increase the number of PICU or hospital days. On admission, normal initial blood gases and the absence of high oxygen requirements were useful in selecting responders to HFNC. Further randomized and multicenter clinical trials are needed to verify these data.
INTRODUCCIÓN: El asma es una causa frecuente de ingreso en la unidad de cuidados intensivos pediátricos (UCIP). En este, cuadro el uso de cánula nasal de alto flujo (CNAF) se ha visto extendido. En este trabajo se describe el tratamiento global en la UCIP ante el ingreso por asma en un hospital monográfico pediátrico y se evalúa la respuesta al uso de la CNAF, comparando la evolución de los pacientes con aquellos que recibieron ventilación no invasiva (VNI). MÉTODOS: Se llevó a cabo un estudio observacional prospectivo (de octubre del 2017 a octubre del 2019). Se describieron epidemiología, clínica, tratamiento y soporte respiratorio. Para la comparación se crearon tres grupos de pacientes: 1) solo CNAF; 2) CNAF y VNI; y 3) solo VNI. RESULTADOS: Se incluyeron 76 pacientes. La mediana de edad fue de dos años y un mes; la mediana de índice pulmonar fue 5. La mediana de ingreso en UCIP fue de tres días y de ingreso hospitalario, seis días. Los niños con solo CNAF (56/76) mostraron menos días de UCIP (p = 0.025) y no requirieron VNI (6/76). También mostraron mayor SatO2/FiO2 (saturación de oxígeno/fracción de oxígeno inspirado) (p = 0.025) y menor nivel de PCO2 (presión parcial de CO2) (p = 0.032). La VNI se utilizó primero siempre en el grupo que recibió ambas modalidades (14/76). No se encontraron diferencias epidemiológicas o clínicas entre grupos. CONCLUSIONES: En nuestra serie, el uso de CNAF no aumentó los días de ingreso en la UCIP ni de hospital. Tampoco requirió cambio a VNI. Al ingreso, una gasometría normal y bajo requerimiento de oxígeno permitieron seleccionar a los pacientes respondedores. Se necesitan más ensayos multicéntricos clínicos aleatorizados para verificar estos datos.

RESUMEN
AIM: The immune status of children recovering from SARS-CoV-2 infection is not completely understood. We describe IgG antispike persistence in children infected during the first two pandemic waves. In addition, we compared with healthy controls their leukocyte populations and CD64 expression. METHODS: Cross-sectional study. Carried out from October 2021 to February 2022 in nonreinfected and nonvaccinated children with SARS-CoV-2 in 2020. The presence of antispike IgG was studied using chemiluminescent immunoassay. Leukocyte populations were analysed using flow cytometry and marked for CD45, CD4, CD8 and CD64. Statistical minor than 0.05 was considered significant. RESULTS: One hundred and eighty-three control and 77 patients were included. IgG antispike determinations were performed after a median of 501 days (262-464); 52 of 77 children were positive. Cases showed significantly higher percentages of monocytes, lymphocytes, CD8+ and CD4+ . In addition, CD64 expression was higher in monocytes and neutrophils. The presence of IgG antispike was accompanied by a higher percentage of CD64+ neutrophils. CONCLUSION: In our series, the SARS-CoV-2 IgG antispike protein was usually positive beyond 1 year after infection. Furthermore, leukocyte populations from cases differ from controls, with higher CD64 expression on neutrophils and monocytes. Prospective clinical observations are required to confirm the implications of these findings.

BACKGROUND: A new clinical syndrome named Paediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2 (PIMS-TS) has been described. This new disease is a leading cause of hospital and paediatric intensive care unit (PICU). It has been related to immunity dysregulation. METHODS: Prospective-retrospective observational study to describe the innate cell signature and immunophenotype of children admitted to PICU because of PIMS-TS (from March 2020 to September 2020). The immunophenotype was done through the expression analysis of these proteins of mononuclear cells: CD64, CD18, CD11a and CD11b. They were compared with previous healthy controls and children admitted to PICU because of bacterial infection, viral infection and Kawasaki disease (KD). Two hundred and forty-seven children were studied: 183 healthy controls, 25 viral infections, 20 bacterial infections, 6 KD and 13 PIMS-TS. RESULTS: PIMT-TS showed the lowest percentage of lymphocytes and monocytes with higher relative numbers of CD4+ (p = .000). Monocytes and neutrophils in PIMS-TS showed higher levels of CD64 expression (p = .000). Also, CD11a and CD11b were highly expressed (p =,000). CONCLUSION: We observed a differential cell innate signature in PIMS-TS. These findings are consistent with a proinflammatory status (CD64 elevated expression) and lymphocyte trafficking to tissues (CD11a and CD11b). More studies should be carried out to confirm our results.

BACKGROUND: Multisystem inflammatory syndrome temporally associated with COVID-19 (MIS-C) has been described as a novel and often severe presentation of SARS-CoV-2 infection in children. We aimed to describe the characteristics of children admitted to Pediatric Intensive Care Units (PICUs) presenting with MIS-C in comparison with those admitted with SARS-CoV-2 infection with other features such as COVID-19 pneumonia. METHODS: A multicentric prospective national registry including 47 PICUs was carried out. Data from children admitted with confirmed SARS-CoV-2 infection or fulfilling MIS-C criteria (with or without SARS-CoV-2 PCR confirmation) were collected. Clinical, laboratory and therapeutic features between MIS-C and non-MIS-C patients were compared. RESULTS: Seventy-four children were recruited. Sixty-one percent met MIS-C definition. MIS-C patients were older than non-MIS-C patients (p = 0.002): 9.4 years (IQR 5.5-11.8) vs 3.4 years (IQR 0.4-9.4). A higher proportion of them had no previous medical history of interest (88.2% vs 51.7%, p = 0.005). Non-MIS-C patients presented more frequently with respiratory distress (60.7% vs 13.3%, p < 0.001). MIS-C patients showed higher prevalence of fever (95.6% vs 64.3%, p < 0.001), diarrhea (66.7% vs 11.5%, p < 0.001), vomits (71.1% vs 23.1%, p = 0.001), fatigue (65.9% vs 36%, p = 0.016), shock (84.4% vs 13.8%, p < 0.001) and cardiac dysfunction (53.3% vs 10.3%, p = 0.001). MIS-C group had a lower lymphocyte count (p < 0.001) and LDH (p = 0.001) but higher neutrophil count (p = 0.045), neutrophil/lymphocyte ratio (p < 0.001), C-reactive protein (p < 0.001) and procalcitonin (p < 0.001). Patients in the MIS-C group were less likely to receive invasive ventilation (13.3% vs 41.4%, p = 0.005) but were more often treated with vasoactive drugs (66.7% vs 24.1%, p < 0.001), corticosteroids (80% vs 44.8%, p = 0.003) and immunoglobulins (51.1% vs 6.9%, p < 0.001). Most patients were discharged from PICU by the end of data collection with a median length of stay of 5 days (IQR 2.5-8 days) in the MIS-C group. Three patients died, none of them belonged to the MIS-C group. CONCLUSIONS: MIS-C seems to be the most frequent presentation among critically ill children with SARS-CoV-2 infection. MIS-C patients are older and usually healthy. They show a higher prevalence of gastrointestinal symptoms and shock and are more likely to receive vasoactive drugs and immunomodulators and less likely to need mechanical ventilation than non-MIS-C patients.

INTRODUCCIÓN: En este momento existen todavía grandes interrogantes acerca de las características de enfermedad causada por el nuevo coronavirus (COVID-19) en los niños, así como acerca de los factores asociados al desarrollo de formas graves de la enfermedad. MÉTODOS: Estudio retrospectivo que incluye pacientes menores de 18 años ingresados debido a infección por SARS-CoV-2. La infección fue confirmada por la reacción en cadena de la transcriptasa inversa-polimerasa (RT-PCR) en tiempo real o por serología. Describimos los datos epidemiológicos y clínicos, los hallazgos de laboratorio y de imágenes, así como el tratamiento y la evolución de estos pacientes. Los pacientes se clasificaron en dos grupos de gravedad y luego se compararon. RESULTADOS: Se incluyeron 39 niños, con una mediana de edad de nueve años (rango 12 días-16 años); 23 eran varones. Los casos con evolución no complicada (24) se presentaron en su mayoría con fiebre y/o síntomas respiratorios sin alteraciones significativas en los hallazgos de laboratorio. De los 15 niños con enfermedad complicada, 12 desarrollaron shock. Además de la fiebre, frecuentemente presentaban alteraciones de la apariencia, taquicardia extrema, dolor abdominal, vómitos, diarrea, erupción cutánea y/o hiperemia conjuntival. También mostraron mayor linfopenia (p = 0,001), elevación de la proporción neutrófilos/linfocitos (p = 0,001), proteína C reactiva (p < 0,001), procalcitonina (p = 0,001), dímero D (p < 0,001) y ferritina (p < 0,001). CONCLUSIONES: La infección por SARS-CoV-2 en niños ingresados se presenta con una gran variabilidad clínica. Cuando se les proporciona tratamiento de soporte, los pacientes con síntomas respiratorios que no tienen alteración de las pruebas de laboratorio, generalmente tienen una enfermedad no complicada. Los pacientes con enfermedad complicada se presentan principalmente con fiebre y síntomas abdominales y/o mucocutáneos, la mayoría desarrollan un shock. La elevación de los marcadores inflamatorios puede permitir una detección temprana y el pronóstico final es bueno
INTRODUCTION: At this time there are still major questions about the characteristics of disease caused by the new coronavirus (COVID-19) in children as well as factors associated with the development of severe forms of the disease. STUDY DESIGN: Retrospective study including patients under 18 years of age admitted with SARS-CoV-2 infection from March 1 to April 30, 2020. Infection was confirmed by realtime reverse transcriptasepolymerase chain reaction (RT-PCR) or antibody testing. We describe the epidemiological and clinical data, laboratory and imaging findings, as well as treatment and outcome in these patients. In light of these findings, patients were classified into two severity groups and then compared. RESULTS: Thirty-nine children were included, with a median age of 9 years (range 12 days-16 years); 23 were boys. Cases with uncomplicated disease course (24) mostly presented to the emergency department (ED) with fever and/or respiratory symptoms without significant alterations in laboratory findings. Of the 15 children with a complicated course, 12 developed shock. In addition to fever, they frequently presented altered appearance, extreme tachycardia, abdominal pain, vomiting, diarrhea, rash, and/or conjunctival hyperemia. They also showed greater lymphopenia (p = 0.001), elevated neutrophil/lymphocyte ratio (p = 0.001), C-reactive protein (p < 0.001), procalcitonin (p = 0.001), D-dimer (p < 0.001), and ferritin (p < 0.001). CONCLUSIONS: SARS-CoV-2 infection in admitted children presents with great clinical variability. When provided supportive care, patients with predominant respiratory symptoms without altered laboratory-test results generally have an uncomplicated course. Patients with complicated disease present mainly with fever and abdominal and/or mucocutaneous symptoms. Most develop shock. Elevation of inflammatory markers may allow for early detection and the final outcome is good

INTRODUCTION AND OBJECTIVES: Acute bronchiolitis (AB) is the leading cause of hospitalization in infants and around 5% require intensive care treatment. Early identification of children diagnosed with AB at a high risk of severe progression is of great interest. The receptor for advanced glycation end products (RAGE), highly expressed in lung tissue, regulates immune responses and inflammation, and its soluble form, sRAGE, is believed to have an anti-inflammatory role. We hypothesized serum sRAGE might be a major determinant of AB severity and prognosis. This study was conducted to measure serum sRAGE in infants with severe AB and to assess its correlation with clinical severity, immediate complications, and outcome. METHODS: Single-center, prospective, observational study of hospitalized children with severe bronchiolitis admitted to the Pediatric Intensive Care Unit (PICU), from September 2015 to September 2016. RESULTS: A total of 52 children and 27 controls were included. The cases age ranged from 11 days to 21 months, resulting in a significant age difference with controls (11.85 vs 4.84 months, P < .01). Serum levels of sRAGE were lower but not significant in severe AB patients than in controls (1350.93 vs 1450.42 pg/mL; P = .399). No correlation was found between serum sRAGE and causative viruses, clinical symptoms, Wood-Downes score (a clinical severity score) on admission, respiratory support, or length of hospital stay. Serum sRAGE was also lower in the cases having had a previous respiratory disease (1463.84 vs 1072.43 pg/mL; P = .049). However, it was higher in patients with any lung consolidation on the chest X-ray (1584.79 vs 1131.62 pg/mL; P = .044) and weakly positively correlated with classical biomarkers (maximum C-reactive protein, +0.295, P = .034; maximum procalcitonin, +0.309; P = .029). CONCLUSION: This single-center study reveals that sRAGE couldn't predict AB severity or outcome in children hospitalized at PICU. Nevertheless, it significantly increased in the presence of any lung consolidation and had a positive correlation with classical biomarkers. The utility of sRAGE in this population could be probably elucidated with a better understanding of AGE-RAGE axis.

We describe 5 children with severe SARS-CoV-2 infection, hemodynamic instability and suspected acute abdomen. This form of the disease has not been previously documented. Four of the cases were confirmed SARS-CoV-2 infection and 1 probable. All of them were previously healthy and needed a pediatric critical care unit admission. The respiratory symptoms were not dominant or were absent. Also, fever was observed. Laboratory testing revealed lymphopenia and high levels of C-reactive protein and procalcitonin with D-dimer, ferritin and interleukin-6 usually elevated. Respiratory support and inotropic support were almost always necessary. In all of them, deterioration occurred on the day of admission.

OBJECTIVES: Spain has been one of the countries most severely affected by the coronavirus disease 2019. This study aims to describe a series of children admitted to a PICU due to coronavirus disease 2019 infection. DESIGN: Prospective observational study. SETTING: Tertiary hospital in Madrid, Spain. PATIENTS: Children admitted to the PICU with severe acute respiratory syndrome coronavirus 2 (severe acute respiratory syndrome coronavirus 2) infection, from March 1, 2020, to April 15, 2020. INTERVENTIONS: Observational study. MEASUREMENTS AND MAIN RESULTS: Epidemiologic data, previous clinical characteristics, support therapy needed, imaging tests, laboratory observations on admission, and pharmacologic therapy. Eleven children were admitted to the PICU, with suspected coronavirus disease 2019; the polymerase chain reaction test was positive in seven. The median age was 100.7 months (range, 0.5-162). Five were admitted from the emergency department and two from the ward. The Pediatric Sequential Organ Failure Assessment score was 3 (range, 0-9), and Pediatric Risk of Mortality II score was 4 (range, 0-16). All children were previously healthy except one (allogeneic hematopoietic stem cell transplantation). Respiratory symptoms and fever were prevalent. A chest radiograph led to a pneumonia diagnosis. Not all patients presented with lymphopenia on admission. D-Dimer and ferritin were elevated. All patients needed oxygen therapy through a nasal cannula; five patients received high-flow nasal cannula therapy, which was later substituted with noninvasive ventilation in four. Mechanical ventilation was necessary in two patients on the first day of PICU admission. Two children required mechanical ventilation and inotropic support. Tocilizumab was applied in two intubated children. Also, four children received heparin. No patients died. CONCLUSIONS: On the whole, the children were previously healthy and are more than 1 year old. Respiratory symptoms were the leading cause of PICU admission, making respiratory support the principal therapy. Patients requiring mechanical ventilation showed deterioration on the first day of admission. These children seemed to require close monitoring, and multicenter studies are necessary.
