Multisystem Inflammatory Syndrome in Children (MIS-C) Associated with COVID-19-PIMS-grade 3: A Case Report

Background: In the face of the rise of COVID-19, the multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 has been reported, and an increase in MIS-C cases has been observed throughout the world. The majority of these cases were similar to Kawasaki disease concerning clinical presentation. Case Presentation: Despite similarities, MIS-C cases present clinical and laboratory differentiation, which makes it essential to portray similar cases worldwide to have a better consensus in the future. A 7-year-old male child visited the hospital with the chief complaints of fever associated with chills, rigors, and excessive myalgia for 3 days. He had a history of elevated high C-reactive protein (CRP) of 42.7 mg/L. He was diagnosed with Paediatric inflammatory multisystem syndrome (PIMS)-grade 3. Here, for the first time, we bring an Indian MIS-C case with COVID-19-associated Paediatric inflammatory multisystem syndrome (PIMS)-grade 3. Conclusion: PIMS-TS infection in paediatrics is associated with a wider range of complications, and the importance of musculoskeletal complications in PIMS-TS has been discussed.
