Successful extracorporeal membrane oxygenation therapy in a child with coronavirus 2019 disease-associated ARDS and chemotherapy for Ewing's sarcoma.

Most children and adolescents with SARS-CoV-2 infection show no or mild symptoms, but those with medical histories can be susceptible to more severe forms of disease. There are few reported cases of extracorporeal membrane oxygenation (ECMO) in pediatric patients with coronavirus disease 2019 (COVID-19). We present a previously healthy 13-year-old male diagnosed with metastatic Ewing's sarcoma at the same time as catastrophic acute respiratory distress syndrome due to COVID-19, who was successfully supported by venovenous-ECMO while he received the corresponding chemotherapy protocol.ECMO can be used as salvage therapy in oncology pediatric patients with respiratory failure secondary to COVID-19. In addition, successful chemotherapy can be administered while patients are supported on ECMO.

Pediatric Inflammatory Multisystem Syndrome Temporally Associated with SARS-CoV-2 Treated with Tocilizumab.

We describe a case of Pediatric Inflammatory Multisystem Syndrome temporally associated with SARS-CoV-2 (PIMS-TS) in an 8-year-old child. The patient developed multiorgan dysfunction, including mixed shock, cardiac dysfunction with myocarditis, pneumonia, acute kidney failure, and gastrointestinal involvement characterized by inflammation of the wall of the bowel and pancreatitis. After treatment with Tocilizumab and corticoid therapy, he presented clinical improvement and normalization of inflammatory markers. PIMS-TS is a new disease developed in a small percentage of patients, so a high degree of suspicion is necessary to establish the diagnosis. Supportive care is of paramount importance. The use of Tocilizumab to control the inflammatory response is likely to be beneficial, but the best immunotherapeutic agent has not yet been established. Randomized clinical studies should be run to determine the best treatment.

Multisystem Inflammatory Syndrome in Children, Chile, May-August 2020.

We describe 26 children with multisystem inflammatory syndrome associated with coronavirus disease in the pediatric intensive care unit of Roberto del Río Hospital (Santiago, Chile). In total, 10 (38.5%) children required mechanical ventilation; 13 (50.0%) required inotropic support. In addition, 18 (69.2%) patients had echocardiographic abnormalities. No patients died.
