Pediatric rheumatology

Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C) in a Middle Eastern patient cohort

Pediatr Rheumatol Online JPublished Retrospective descriptive comparative cohort study

Authors' conclusion

This study showed vast similarities between KD and MIS-C, suggesting that they lie along the same clinical spectrum. However, there are several differences between the two disease entities suggesting that MIS-C most likely represents a new severe variant of KD.
