    Background: Since mid-April 2020, cases of multisystem inflammatory syndrome MESHD in children TRANS (MIS-C) associated with coronavirus disease MESHD (COVID-19) that mimic Kawasaki disease MESHD ( KD MESHD) have been reported in Europe and North America. However, no cases have been in East Asia, where KD MESHD is more prevalent.Case presentation: A previously healthy 11-year-old boy was admitted with a 4-day history of fever HP fever MESHD and abdominal pain HP abdominal pain MESHD. He had no contact history to any patient with COVID-19. Blood SERO acute inflammatory markers were highly elevated. He was treated with antibiotics for suspected bacterial enteritis MESHD, but he suddenly developed hypotension HP hypotension MESHD. Inotropics and intravenous immunoglobulin were administered to manage septic shock MESHD shock HP. On hospitalization day 6, he developed signs and symptoms of KD MESHD (conjunctival injection, strawberry tongue HP, cracked lip MESHD, and coronary artery dilatation MESHD dilatation HP) in addition to pleural/pericardial effusion MESHD pericardial effusion HP and mesenteric lymphadenitis HP lymphadenitis MESHD. The results of microbiologic tests, including reverse-transcription polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), were negative. Fluorescent immunoassay SERO and enzyme-linked immunosorbent assay SERO revealed abundant IgG antibodies SERO against SARS-CoV-2 in his serum SERO, but no IgM antibodies SERO. He was discharged successfully on day 13.Conclusion: MIS-C may occur in children TRANS with a previously asymptomatic TRANS COVID-19 infection MESHD. A high index of suspicion is required for this novel syndrome in unusual cases of KD MESHD or KD shock syndrome MESHD shock HP syndrome with multisystem inflammation MESHD, even when there is no clear history of contact or symptoms of COVID-19.

    BackgroundChildren are relatively spared from Coronavirus disease MESHD 2019 (COVID-19), but some severe cases have been reported. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection MESHD in children TRANS may affect the cardiovascular system. We hereby report about a case of myocarditis HP myocarditis MESHD evolving to cardiogenic shock HP cardiogenic shock MESHD in a SARS-CoV-2 positive child TRANS.Case presentationAn otherwise healthy 12-year-old patient was admitted with fever HP fever MESHD, vomiting HP vomiting MESHD, diarrhoea and drowsiness MESHD drowsiness HP, without any respiratory symptoms. He was diagnosed with COVID-19 on nasopharyngeal swab. He developed hypotension HP hypotension MESHD and cardiogenic shock HP cardiogenic shock MESHD. Bedside echocardiography revealed left ventricular impairment MESHD with an ejection fraction (LVEF) below 25%. Plasmatic markers of myocardial injury MESHD were remarkably raised, as well as inflammatory biomarkers, including procalcitonin (highest recorded value: 66 ng/mL) and interleukin-6 (8209 pg/mL). The child TRANS was transferred to Intensive Care Unit and he was treated with catecholamine support, mechanical ventilation and empiric anti-infectious therapy, including broad spectrum antibiotics and the antiviral agent remdesivir. All additional microbiological investigations yielded negative results. We observed a gradual improvement of LVEF within 5 days. A cardiac magnetic resonance confirmed the suspicion of myocarditis HP myocarditis MESHD. After 21 days of hospitalisation, the child TRANS was discharged without sequelae.ConclusionsOur hypothesis is that the child TRANS suffered from SARS-CoV-2-induced fulminant myocarditis HP myocarditis MESHD, probably in the setting of cytokine release syndrome (CRS). The peculiarity of this SARS-CoV-2 infection MESHD is the presence of cardiac failure MESHD in a previously healthy child TRANS without a respiratory illness MESHD. The positive outcome is in line with published Literature about the overall better prognosis of COVID-19 children TRANS compared to adults TRANS. Remdesivir, an investigational antiviral therapy, may have played a role on the clinical improvement of the child TRANS.
