Hyperinflammatory Syndrome in Children Associated With COVID-19: Need for Awareness.

The pandemic of COVID-19 initially appeared to cause only a mild illness in children. However, it is now apparent that a small percentage of children can develop a hyperinflammatory syndrome labeled as Pediatric inflammatory multisystem syndrome - temporally associated with SARS-CoV-2 (PIMS-TS). Features of this newly recognized condition may include persistent fever, evidence of inflammation, and single or multi-organ dysfunction in the absence of other known infections. Some of these children may share features of Kawasaki disease, toxic shock syndrome or cytokine storm syndrome. They can deteriorate rapidly and may need intensive care support as well. The PCR test is more often negative; although, most of the children have antibodies to SARS-CoV-2. Although the pathogenesis is not clearly known, immune-mediated injury has been implicated. We herein provide current information on this condition, in order to raise awareness amongst pediatricians.
