Multisystem Inflammatory Syndrome in Children (MIS-C) and adults (MIS-A) is associated with SARS-CoV-2 infection with unknown pathogenesis. I propose that high SARS-CoV-2 antibody levels are contributing to hyper-activated mast cells driving disease pathogenesis. Multiple scenarios that result in sufficiently high antibody levels are proposed including ongoing persistent infections, subsequent infections associated with secondary antibody immune responses, etc. Candidate adjunctive therapy treatments are proposed based on COVID-19 patients efficacy responses to treatments targeting activated mast cells and virus elevated prostaglandin-endoperoxide synthase 2 (PTGS2)/cyclooxygenase-2 (COX-2) levels.
Keywords: MIS-C, MIS-A, Multisystem inflammatory syndrome, Mast cells
