Clinical characteristics of pediatric patients with acute respiratory distress syndrome due to COVID-19.

BACKGROUND: There are only a few reports of acute respiratory distress syndrome (ARDS) in patients with SARS-CoV-2 in pediatrics. This study aimed to describe the characteristics of critically ill pediatric patients with COVID-19, the frequency of ARDS, ventilatory mechanics and results of prone position. METHODS: We conducted a retrospective, observational study of patients admitted to the pediatric intensive care unit (PICU) between April 1 to September 30, 2020. RESULTS: Thirty-four patients were admitted to pediatric intensive care unit, 31.7% were SARS-CoV-2 positive. 13 presented ARDS, 11 required invasive mechanical ventilation, and seven were pronated as an oxygenation strategy. All patients classified as severe ARDS were pronated. Obesity was the most important comorbidity. The complications associated with ARDS were multisystemic inflammatory syndrome (8 vs. 4; p < 0.05) and acute kidney injury (8 vs. 3; p < 0.05). Procalcitonin was higher in patients with ARDS, as were the days of stay in PICU (p < 0.05). The success of the pronation maneuver was achieved 8 hours later , with the following results: arterial oxygen partial pressure to fractional inspired oxygen ratio 128 vs. 204, oxygenation index 8.9 vs. 5.9, static lung compliance 0.54 vs. 0.70 ml/cmH2O/kg, plateau pressure 24 vs. 19 cmH2O (p < 0.05). The use of narcotics was higher in the group with ARDS plus pronation 124 vs. 27 hours in the non-pronated (p < 0.01). Mortality associated with SARS-CoV-2 was 5.8%. CONCLUSIONS: ARDS was presented in 38.2% of the children admitted to PICU and was more frequent in obese patients. Pronation, performed in severe cases, improved oxygenation and lung mechanics indexes. No patient died of ARDS.

INTRODUCCIÓN: Existen pocos reportes de síndrome de dificultad respiratoria aguda (SDRA) con COVID-19 en pacientes pediátricos. El objetivo de este estudio fue describir las características de los pacientes pediátricos críticamente enfermos con COVID-19, la frecuencia del SDRA, la mecánica ventilatoria y los resultados de la posición prona. MÉTODOS: Se llevó a cabo un estudio retrospectivo y observacional de los pacientes ingresados del 1 de abril al 30 de septiembre de 2020. RESULTADOS: Ingresaron 34 pacientes a la unidad de terapia intensiva pediátrica (UTIP) con prueba positiva para SARS-CoV-2. De ellos, 13 presentaron SDRA, 11 requirieron ventilación mecánica invasiva y siete fueron pronados como estrategia de oxigenación. Todos los pacientes clasificados como SDRA graves fueron pronados. La obesidad fue la comorbilidad más importante. Las complicaciones asociadas con SDRA fueron el síndrome inflamatorio multisistémico (p < 0.05) y la lesión renal aguda (p < 0.05). La procalcitonina fue mayor en los pacientes con SDRA, al igual que los días de estancia en la UTIP (p < 0.05). El éxito de la maniobra de pronación se alcanzó 8 horas después.Los resultados observados fueron los siguientes relación presión arterial de oxígeno/fracción inspirada de oxígeno 128 vs. 204, índice de oxigenación 8.9 vs. 5.9, distensibilidad pulmonar estática 0.54 vs. 0.70 ml/cmH2O/kg, y presión meseta 24 vs. 19 cmH2O (p < 0.05). El uso de narcóticos fue mayor en el grupo de SDRA más pronación que en los no pronados (124 vs. 27 h; p < 0.01). La mortalidad asociada con SARS-CoV-2 fue del 5.8%. CONCLUSIONES: El SDRA se presentó en el 38.2% de los niños admitidos a UTIP, y con mayor frecuencia en los pacientes con obesidad. La maniobra de pronación aplicada en los casos severos, mejoró la oxigenación de la mécanica pulmonar. Ninguno de los pacientes falleció por SDRA.

Descriptive study of adverse drug reactions in a tertiary care pediatric hospital in México from 2014 to 2017.

INTRODUCTION: In Pediatrics, adverse drug reactions (ADRs) affect morbidity and mortality. In Mexico, the characteristics of ADRs and suspect drugs have not been described in hospitalized children. OBJECTIVE: To estimate the frequency of ADRs and describe them, as well as suspect drugs, in a tertiary care pediatric hospital in Mexico. METHODS: A total of 1,649 Hospital Infantil de Mexico Federico Gómez ADR reports were analyzed. Completeness of the information was assessed, and ADRs severity and seriousness were assigned based on NOM-220-SSA1-2012, with causality being established according to the Naranjo algorithm. ADRs were classified with WHO Adverse Drug Reaction Terminology (WHO-ART). The drugs involved in ADRs were categorized according to the Anatomical Therapeutic Chemical (ATC) classification. Descriptive analysis was performed using the SPSS 20 statistical package. RESULTS: Of all the reports, 5.8% lacked sufficient information for the analysis (grade 0). ADRs frequency ranged from 2.12% to 8.07%. ADRs occurred most commonly in children (56.9%), in the female gender (52%), in subjects with normal BMI Z-score (46.6%) and malnutrition (35.3%), diagnosed with neoplasms (72.2%) and in the Emergency Department (70.0%). ADRs were severe in 14.4% of cases, in 81.0% they were serious and 2.1% were classified as definite. Most common serious ADR was febrile neutropenia (44.5%). The 0.7% of patients recovering with sequelae; 1.1% died (with the medication being associated) and 70.3% were admitted to the hospital as a result of an ADR. Antineoplastic and immunomodulating agents were more commonly associated with serious ADRs. CONCLUSION: ADRs affected morbidity and mortality, which is why strengthening pharmacovigilance programs in Mexican pediatric hospitals is necessary.
