Dr. Bas Vastert, Care Transformation in Childhood Arthritis via Precision Medicine: sJIA treatment ⭐️cytokine monitoring, especially IL-18 ⭐️T2T with biologic first approach in Netherlands- most patients don’t receive any GCs #ACR25 #ACRambassador

Dr. Bas Vastert, Care Transformation in Childhood Arthritis via Precision Medicine: Window of opportunity ⭐️in non-systemic #JIA: ⬆️ inactive disease with earlier biologic start (<6mo) ⭐️in sJIA: integrating biomarkers in clinical care, early targeted tx #ACR25 #ACRambassador

Dr. Rae Yeung, Understanding and Harnessing the Biology of Arthritis 4. Naming is important because guides therapy #ACR25 #ACRambassador #kidsgetarthritistoo

Dr. Rae Yeung, Understanding and Harnessing the Biology of Arthritis 3. UCAN Biologic Classification: lots of patients and large amount of data yielded 5 clusters with clinical and biologic characteristics and distinct patterns of joint involvement #ACR25 #ACRambassador

Dr. Rae Yeung, Understanding and Harnessing the Biology of Arthritis 1. JIA classification has been a journey. Not every patient finds a home, & peds doesn’t consistently translate to adult classification. Is there a way to do this from a biologic basis? #ACR25 #ACRambassador

Looking forward to starting my day off in the Networking Lounges for the AMIGO event at 8:20 AM. Hope to see many fellow #pedsrheum there! #ACR25 #ACRambassador
