In this episode, we speak with Dr. Jayne MacMahon about an international collaborative study in juvenile dermatomyositis (JDM) involving pediatric rheumatology centers in Genoa, Italy, and Toronto, Canada. She discusses the study's motivation, key disease activity measures, treatment targets, and definitions of remission, along with major findings on time to remission, steroid exposure, and treatment outcomes across cohorts. Dr. MacMahon also reflects on the study's limitations, future research directions, her career path in pediatric rheumatology, and how international collaboration can shape the future of care for children with autoimmune diseases.
