The 2026 ACR Guidelines for Juvenile Idiopathic Arthritis (JIA) are here, and lead author Dr. Karen Onel joins us to unpack the key updates shaping pediatric rheumatology care. From a biologics-first approach in systemic JIA to more individualized treatment pathways for non-systemic disease, the new recommendations emphasize earlier intervention, faster treatment tailoring, and risk-based decision-making. Dr. Onel also discusses the guidelines' broader focus on mental health, physical activity, rehabilitation, and the challenges of growing up with a chronic illness. More than an update to treatment algorithms, these guidelines reflect a fundamental shift in philosophy—one that puts the whole child, not just the diagnosis, at the center of care.
