ABSTRACT
Latin America (LATAM) children offer special insight into Severe Acute Respiratory Syndrome Coronavirus 2 (SARS COV2) due to high-risk race/ethnicity, variability in medical resources, diverse socioeconomic background, and numerous involved organ systems. This multinational study of LATAM youth examined the distinguishing features of acute or late multisystem SARS COV2 with versus without cardiac involvement. A consecutive sample of youth 0-18 years old (N = 98;50% male) presenting with multisystem SARS COV2 to 32 centers in 10 Latin American countries participating in a pediatric cardiac multi-imaging society were grouped as with versus without cardiac involvement, defined as abnormal echocardiographic findings or arrhythmia. Collected clinical data were analyzed by Student's t-test or Fisher's exact test. Cardiac (N = 48, 50% male) versus no cardiac (N = 50, 50% male) were similar in age; weight; nonrespiratory symptoms; and medical history. The cardiac group had 1 death and symptoms including coronary artery dilation, ejection fraction <50%, pericardial effusion, peripheral edema, arrhythmia, and pulmonary artery thrombus. The cardiac group had higher risk of ICU admission (77% vs 54%, p = 0.02); invasive ventilation (23% vs 4%,p = 0.007); vasoactive infusions (27% vs 4%, p = 0.002); prominent respiratory symptoms (60% vs 36%, p < 0.03); abnormal chest imaging (69% vs 34%, p = 0.001); troponin (33% vs 12%, p = 0.01); alanine aminotransferase (33% vs 12%, p = 0.02); and thrombocytopenia (46% vs 22%, p = 0.02). Receiver operating curve analysis showed that abnormal laboratories had 94% sensitivity and 98% negative predictive value on the need for ICU interventions.Conclusion: In LATAM children with multisystem SARS COV2, cardiac involvement was prevalent. Cardiac involvement was more likely to require ICU interventions, certain abnormal labs, and respiratory involvement. What is Known: ⢠SARS COV2 can be asymptomatic in children but in some cases can have serious multisystemic involvement. ⢠Hispanic ethnicity is purportedly at high risk of SARS COV2 in nations where they are often disadvantaged minority populations. What is New: ⢠Latin American children presenting with multisystem SARS COV2 frequently have cardiac involvement which was associated with ICU interventions; prominent respiratory symptoms; abnormal chest X-ray; elevated troponin, ALT, and thrombocytopenia. ⢠Elevated troponin, ALT or thrombocytopenia had high sensitivity and negative predictive value on the need for intensive care interventions.

A 27 años del nacimiento del Hospital Garrahan, hemos sentido la necesidad de compartir con el equipo de salud las estrategias de atención del niño y su familia utilizadas en nuestro Hospital, colaborar con su actualización permanente y poner énfasis en el trabajo interdisciplinario. En este tomo desarrollamos el tema del niño con cardiopatía congénita. Se trata de la malformación congénita grave más frecuente, que se presenta en aproximadamente 5 a 8 cada mil nacidos vivos. En Argentina, nacen alrededor de 700.000 niños cada año, es decir alrededor de 4.500 con esta patología. La supervivencia actual con calidad de vida futura normal es alta para la mayoría de estos niños. A esto contribuyen las mejoras en el diagnóstico prenatal y neonatal temprano, el traslado seguro, la estabilización preoperatoria y el tratamiento por equipos cardiovasculares interdisciplinarios. El rol del pediatra es fundamental en el diagnóstico y seguimiento de estos pacientes. En este volumen, el pediatra encontrará aspectos epidemiológicos y patogénicos de algunas de las enfermedades más prevalentes, así como claves para el diagnóstico oportuno, con énfasis en la semiología y los estudios complementarios accesibles, indicaciones de derivación, prevención de riesgos y asesoramiento general para pacientes y padres.
