Baja incidencia de cardiopatía clínicamente significativa en niños en edad escolar tras padecer COVID-19 / The low incidence of clinically significant heart disease in school-age children following COVID-19

No es clara la carga de morbimortalidad de la lesión cardíaca clínicamente evidente secundaria a la enfermedad por coronavirus de 2019 (COVID-19) en los niños en edad escolar. A lo largo de 12 meses, en un importante hospital pediátrico académico en la región del medio oeste de Estados Unidos, hubo 1481 casos de COVID-19 sin hospitalización en niños en edad escolar por lo demás sanos, en quienes se hicieron 195 pruebas cardíacas. Si bien aparecieron hallazgos fortuitos, no se descubrió ninguna patología cardíaca relacionada con la COVID-19. Además, ~3 % de los niños solamente tuvieron síntomas cardíacos agudos que requirieron una evaluación por el área de cardiología pediátrica. Los niños que no fueron hospitalizados por COVID-19 tienen un riesgo muy bajo de desarrollar daño cardíaco clínicamente significativo y son más propensos a presentar hallazgos fortuitos.

The burden of clinically-apparent cardiac injury secondary to coronavirus disease 2019 (COVID-19) in school-age children is unclear. Over 12 months at a large academic pediatric hospital in the Midwestern portion of the United States, there were 1481 COVID-19 positive non-hospitalized otherwise healthy schoolaged children with 195 having cardiac testing performed. While incidental findings occurred, no definitive COVID-19 related cardiac pathology was discovered. Additionally, only ~3 % of children had acute cardiac symptoms necessitating evaluation by pediatric cardiology. School-age children who were not hospitalized for COVID-19 have a very low risk of having clinically significant cardiac damage and are more likely to discover incidental findings.

Variation in Pharmacologic Management of Patients with Kawasaki Disease with Coronary Artery Aneurysms.

OBJECTIVE: To evaluate practice variation in pharmacologic management in the International Kawasaki Disease Registry (IKDR). STUDY DESIGN: Practice variation in intravenous immunoglobulin (IVIG) therapy, anti-inflammatory agents, statins, beta-blockers, antiplatelet therapy, and anticoagulation was described. RESULTS: We included 1627 patients from 30 IKDR centers with maximum coronary artery aneurysm (CAA) z scores 2.5-4.99 in 848, 5.0-9.99 in 349, and ≥10.0 (large/giant) in 430 patients. All centers reported IVIG and acetylsalicylic acid (ASA) as primary therapy and use of additional IVIG or steroids as needed. In 23 out of 30 centers, (77%) infliximab was also used; 11 of these 23 centers reported using it in <10% of their patients, and 3 centers used it in >20% of patients. Nonsteroidal anti-inflammatory agents were used in >10% of patients in only nine centers. Beta-blocker (8.8%, all patients) and abciximab (3.6%, all patients) were mainly prescribed in patients with large/giant CAAs. Statins (2.7%, all patients) were mostly used in one center and only in patients with large/giant CAAs. ASA was the primary antiplatelet modality for 99% of patients, used in all centers. Clopidogrel (18%, all patients) was used in 24 centers, 11 of which used it in >50% of their patients with large/giant CAAs. CONCLUSIONS: In the IKDR, IVIG and ASA therapy as primary therapy is universal with common use of a second dose of IVIG for persistent fever. There is practice variation among centers for adjunctive therapies and anticoagulation strategies, likely reflecting ongoing knowledge gaps. Randomized controlled trials nested in a high-quality collaborative registry may be an efficient strategy to reduce practice variation.
