Literature describing patients with concomitant COVID-19 infection with acute appendicitis in pediatric patients is growing, and understanding the clinical picture of such patients is relevant in their treatment. We report 3 male children who were surgically treated for acute appendicitis and had concomitant SARS-CoV-2 infection. Our first patient was a 12-year-old male who presented with symptoms indicative of appendicitis but no respiratory symptoms associated with COVID-19 (eg cough, shortness of breath). Laboratory evaluation revealed leukopenia and an elevated C-reactive protein; imaging was consistent with acute appendicitis and an acute pulmonary viral infection. Though he lacked diffuse peritonitis on physical examination …

The trimeric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S) is the sole viral protein responsible for both viral binding to a host cell and the membrane fusion event needed for cell entry. In addition to facilitating fusion needed for viral entry, S can also drive cell-cell fusion, a pathogenic effect observed in the lungs of SARS-CoV-2-infected patients. While several studies have investigated S requirements involved in viral particle entry, examination of S stability and factors involved in S cell-cell fusion remain limited. A furin cleavage site at the border between the S1 and S2 subunits (S1/S2) has …
