Researchers discover Covid-19 syndrome in children which sees ’profound immune system changes’

While cytokines help the immune system suppress infection, overproduction of these molecules can cause severe inflammation, which can harm the patient.

A newly identified disease that occurs in children and is linked to Covid-19 causes significant changes in the immune system, scientists have said.

Researchers found that young patients with acute paediatric inflammatory multisystem syndrome temporally associated with Sars-CoV-2 infection (PIMS-TS) have raised levels of molecules, called cytokines, and reduced levels of infection-fighting white blood cells, called lymphocytes.
