    Objetivo: Caracterizar el comportamiento de COVID-19 en niños chilenos hospitalizados en unidades de paciente crítico pediátrico (UPCP) y evaluar factores de riesgo para COVID-19 severo. Pacientes y Método: Estudio multicéntrico cohorte prospectivo, pacientes 0-18 años con SARS-CoV-2 confirmado hospitalizados en UPCP. Se registraron variables clínicas, laboratorio, imagenológicas y terapéuticas. Se comparó “COVID-19 leve/moderado” versus “COVID-19 severo” utilizando mediana con rango intercuartil (RIC), test U Mann-Whitney, Test Fisher de dos colas y análisis multivariado binario forward para ajuste de variables para “COVID-19 severo”. Significativo p < 0,05. Resultados: 219 pacientes, 55,3% hombres, mediana edad 86 meses (RIC: 13,5-156). Comorbilidades principales: obesidad, enfermedades respiratorias. Mortalidad global: 3,6%. “COVID-19 severo” (26,5%) mostró más leucopenia, linfopenia, más inflamación y alteración de órganos (p < 0,05). También desarrolló más Sepsis/shock, SDRA y disfunción de órganos, requirió más terapia hemodinámica, antiinflamatoria, anticoagulación, antibioterapia, con mayor estadía en UPCP/hospitalaria (p < 0,05) y mortalidad de 13,8%. Factores de riesgo asociados a “COVID-19 severo”: shock al ingreso (aOR 28,44 [IC95%: 10,45-77,4]), obesidad (aOR 3,55 [IC95%: 1,3-9,6]), condensación (aOR 3,1 [IC95%: 1,1-8,7]), atelectasia (aOR: 8.7 [IC95%: 1,17-64,3]), corticoides dosis de estrés (aOR 7,7 [IC95%: 1,9-30,6]), antibioterapia precoz (aOR: 12,02 [IC95%: 1,11-130,02]), inmunodeficiencia adquirida/ congénita (aOR: 19,2 [IC95%: 1,19-321]) y patología oncológica (aOR: 10,7 [IC95%: 2,14-47,8]). Conclusión: En esta cohorte pediátrica chilena, el perfil de paciente que ingresó a UPCP fue de sexo masculino en edad escolar con comorbilidad asociada. Factores de riesgo asociados a COVID-19 severo fueron: presencia de comorbilidades (inmunodeficiencia adquirida/congénita, patología oncológica y obesidad), shock al ingreso y condensaciones en las imágenes radiológicas.

    Guillain-Barre Syndrome and Hydrocephalus in an infant with Wiskott-Aldrich Syndrome
    (SOC CHILENA PEDIATRIA, 2020) Avila Smirnow, Daniela; Cordova Aguilera, Marcela; Cantillano Malone, Christian; Arriaza Ortiz, Manuel; Wegner Araya, Adriana
    Guillain-Barre Syndrome (GBS) is rarely diagnosed in the first year of life. The association of GBS with Wiskott-Aldrich syndrome (WAS) is even less frequent and has been previously reported in only two children to our knowledge. Hydrocephalus is a known but rare complication of GBS. Objective: To describe the case of an infant in which GBS, WAS and hydrocephalus appear clinically associated. Clinical Case: A nine-months-old male infant with a history of WAS was admitted to our ICU with acute hypotonia and poor general condition. He developed flaccid paralysis, absent deep tendon reflexes, and respiratory failure. A lumbar puncture showed albuminocytologic dissociation. GBS was suspected and an electromyography was performed, showing a demyelinating polyneuropathy. He was successfully treated with intravenous immunoglobulins. During hospitalization, he presented intermittent bradycardia, so a brain CT scan was performed, showing acute hydrocephalus which was managed through an external ventricular drain achieving favorable response. In the long term, the patient underwent bone marrow transplant and had to be reoperated due to valve-related complications. However, his psychomotor development is normal, with no obvious neurological sequelae. Conclusion: We present the third case of GBS in a patient with WAS, which is the first infant younger than one year. Additionally, he presented acute hydrocephalus as a complication of GBS. We suggest considering these three comorbidities since their early diagnosis and prompt management allow better neurological recovery and avoid potentially lethal complications.
