Understanding PJIA & SJIA
Polyarticular juvenile idiopathic arthritis (PJIA) and systemic juvenile idiopathic arthritis (SJIA) are types of juvenile idiopathic arthritis (JIA), a chronic form of arthritis in children. PJIA is characterized by inflammation in five or more joints within the first six months of the disease, while in SJIA, many of the signs and symptoms (such as rash and fever) affect the whole body, and not just the joints.1
