Are Kawasaki Disease and Pediatric Multi-Inflammatory Syndrome Two Distinct Entities? Results from a Multicenter Survey During SARS-CoV-2 Epidemic in Italy

Background: There is mounting evidence on the existence of a childhood multi-inflammatory syndrome related to SARS-CoV-2, sharing similarities with Kawasaki Disease (KD).  Methods: On April 24th,2020 the Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD or KD-like disease. Classification was: 1) classical and incomplete KD, named Kawasaki Disease Group (KDG); 2) KD-like multi-inflammatory syndrome, named KawaCOVID Group (KCG). Demographic, clinical, and laboratory data, treatment information, and patients’ outcome were collected in an online anonymized database (RedCAPO). Chi square test or exact Fisher test and non parametric W…

Case Report: The JAK-Inhibitor Ruxolitinib Use in Aicardi-Goutieres Syndrome Due to ADAR1 Mutation

Type I Interferonopathies comprise inherited inflammatory diseases associated with perturbation of the type I IFN response. Use of Janus kinase (JAK) inhibitors has been recently reported as possible tools for treating some of those rare diseases. We describe herein the clinical picture and treatment response to the JAK-inhibitor ruxolitinib in a 5-year-old girl affected by Aicardi-Goutières Syndrome type 6 (AGS6) due to ADAR1 mutation. The girl's interferon score (IS) was compared with that of her older brother, suffering from the same disorder, who was not treated. We observed a limited, but distinct neurological improvement (Gross Motor Function and Griffiths Mental Development Scales). …
