Acute myocarditis and multisystem inflammatory emerging disease following SARS-CoV-2 infection in critically ill children

Acute myocarditis with intense systemic inflammation and atypical Kawasaki disease is an emerging severe pediatric disease following SARS-CoV-2 infection. Early recognition of this disease is needed and referral to an expert center is recommended.

A delayed and inappropriate host immunological response is suspected. While underlying mechanisms remain unclear, further investigations are required to target an optimal treatment.

20 critically ill children admitted for shock had an acute myocarditis (left ventricular ejection fraction, 35% (25–55); troponin, 269 ng/mL (31–4607)), and arterial hypotension with mainly vasoplegic clinical presentation.

The first symptoms before PICU admission were intense abdominal pain and fever for 6 days (1–10). All children had highly elevated C-reactive protein (> 94 mg/L) and procalcitonin (> 1.6 ng/mL) without microbial cause.
