Abstract:
Macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis (sJIA) is difficult to distinguish from active sJIA or sepsis. A collaborative effort scoring the performance of different clinical diagnostic criteria provides valuable guidance to clinicians, but challenges in the diagnosis of sJIA-related MAS remain.
