ABSTRACT
Multisystem inflammatory syndrome in children (MIS-C) is a rare and serious COVID-19 manifestation characterised by generalised inflammatory response including inflammation of the heart, blood vessels, lungs, kidneys, brain, skin, eyes and gastrointestinal system. Children usually present with fever lasting for 24 hours or more along with other symptoms such as abdominal pain, vomiting, diarrhoea, skin rash, red eyes, and swelling of the lips, tongue, hands and feet. Children with MIS-C usually have negative results for a current infection with COVID-19 but positive antibody results indicating that these children were infected with the COVID-19 virus in the past. We present the case of a 12-month-old girl with multisystem inflammatory syndrome presenting as systemic-onset juvenile idiopathic arthritis (SoJIA) and positive Covid-19 PCR. She was treated successfully with Dexamethasone and Naproxen.
