ABSTRACT
Aim. In COVID-19 Pandemic, a new hyperinflammatory syndrome was reported with clinical features of Kawasaki disease, named PIMS-TS. We want to present a single center experience where the patients were diagnosed with Kawasaki-like in PIMS-TS with cardiac affliction. Material and method: The study was observational and retrospective, enrolled 14 patients fulfilling the criteria of PIMS-TS with the median age of 9 (IQR, 1.6-11), 9 male (64.2 %) and 5 female (35.8 %). Results: ECG revealed tachycardia and ST-T changes in 60% of patients. In evolution, ECG modified in 20% and consisted of long QT in 7% of cases, bradycardia in 7%, 3% transitory sick sinus syndrome and 3% grade I/II Atrio-Ventricular block. Cardiac disfunction was evidenced in 4 patients (28%), with reduced ejection fraction under 50%, mitral insufficiency in 6 (42.8%), pericardial fluid in 8 (57.1%) and perivascular brightness in 8 (57.1%). The cardiac biomarkers: NT-proBNP (increased in 9), cTroponin T (increased in 7) and cTroponin I (increased in 5) confirmed heart dysfunction. During the hospitalization and under medical treatment, all the modifications recover. Evolution was good for 12 children. Conclusions: Cardiac dysfunction and myocardial injury were confirmed by elevated cardiac biomarkers. Rapid recognition allows prompt treatment for a good outcome. NT-proBNP, cTroponin T and I are of capital significance in monitoring the myocardial injury, the treatment and evolution of these patients. © 2021, MediaMed Publicis. All rights reserved.
