Spectre of COVID-19 infection confounding myocarditis related to cytomegalovirus mononucleosis syndrome and hyperinflammatory syndrome.

ABSTRACT: Viral infections have multiple mechanisms of affecting internal and external organs by direct invasion or by molecular mimicry. They have also been described as triggers for inflammatory processes like hyperinflammatory syndrome (HIS), Adult-onset Stills Disease (AOSD), and myocarditis [1]. Here we report an interesting case of a young adult with recent infection with SARS-CoV-2 (COVID-19) who presented with myocarditis requiring circulatory support in the cardiac care unit. During the admission, he was found to have concurrent cytomegalovirus (CMV) mononucleosis syndrome and presentation consistent with HIS resembling AOSD. This patient had multiple etiologies that could have caused myocarditis: CMV infection, COVID-19 infection, and HIS. As noted, viral infections have been proposed as p
