Elevated plasma levels of acute phase proteins in children with MIS-C and COVID-19. A, The plasma levels of CRP, α 2M, haptoglobin, and SAP were measured in MIS-C (n = 44), COVID-19 (n = 33), seropositive (n = 47), and control children (n = 21). The data are presented in scatter violin plots, with each circle representing a single individual. P values were calculated using the Kruskal-Wallis test with Dunn’s post hoc for multiple comparisons. Abbreviations: α 2M, alpha-2 macroglobulin; COVID-19, coronavirus disease 2019; CRP, C-reactive protein; MIS-C, multisystem inflammatory syndrome in children; SAP, serum amyloid P.
