SARS-CoV-2-related Multisystem Inflammatory Syndrome in Adults

Adults infected with SARS-CoV-2 may develop a multisystem inflammatory syndrome (MIS-A) characterized by elevated inflammatory markers and multisystem organ involvement. We report the case of a patient who presented with fever and vomiting at hospital admission. He tested positive for SARS-CoV-2 infection and blood tests showed elevated inflammatory markers. The patient developed acute cardiac dysfunction and shock in less than 24 hours and the echocardiogram revealed an LVEF of 30%. He was discharged 3 weeks later fully recovered. MIS-A should be considered if a compatible syndrome is observed in patients with evidence of SARS-CoV-2 infection by PCR test or serology. LEARNING POINTS: Multisystem inflammatory syndrome should be considered in young adults presenting with shock and elevated inflammatory markers. Multisystem inflammatory syndrome may be highly responsive to parenteral steroids.
