A term infant girl with uneventful antenatal history had an erythematous rash followed by fever from day 8. She was diagnosed with late-onset sepsis and was treated accordingly. She received immunoglobulin for persistent thrombocytopenia, after which there was transient improvement. The patient was transferred to our hospital on day 25 after recurrence of fever, watery diarrhea, and a generalized maculopapular rash. On admission, she had tachycardia, tachypnoea, anemia, thrombocytopenia, hypoalbuminemia, and generalized edema. Reverse transcriptase–polymerase chain reaction results for coronavirus disease 2019 (COVID-19) was positive. Within 12 hours of admission, she developed cardiogenic shock with pulmonary edema and needed invasive ventilation. Echocardiography revealed ejection fraction of 40% with mild pericardial effusion. N-terminal pro–brain natriuretic peptide was 33000 g/L, D-dimer 16500 µg/L, and ferritin 16000 ng/mL. Methylprednisolone, immunoglobulin, and enoxaparin was started, with a diagnosis of multisystem inflammatory syndrome in children, associated with COVID-19. She developed seizures, pulmonary hemorrhage, and cardiac arrest the following day, along with acute kidney injury. She was extubated after 5 days. Steroid was stopped after 5 days because she developed hypertension and echocardiography had normalized. Five days after extubation, she again developed respiratory distress and was ventilated again for 2 days. Echocardiography revealed moderate left ventricular dysfunction, along with secondary elevation of ferritin. Methylprednisolone was restarted and continued for 5 days followed by tapering dose of oral prednisolone, on which she was finally discharged. Although mild myocarditis with COVID-19 has been reported, multisystem inflammatory syndrome in children in a newborn with refractory myocarditis, along with gastrointestinal and renal manifestations, is a rare entity. Dermatologic manifestation of neonatal COVID-19 is also unique.
