• W2897777236 abstract "Objective: To compare sensitivity and specificity of 2005 and newly proposed MAGNIMS 2016 MRI dissemination in space (DIS) criteria for multiple sclerosis (MS) to predict a first clinical neurological event in asymptomatic children with incidental MRI findings consistent with central nervous system demyelination, termed the radiologically isolated syndrome (RIS). Background: The diagnosis of RIS in adults requires that 2005 MRI criteria for DIS be met. We recently identified a cohort of children with RIS using newer validated 2010 DIS criteria (RIS-2010). Robust criteria for RIS in children are needed to better classify risk of developing clinical symptoms and to avoid unnecessary testing or therapies. Design/Methods: We analyzed a historical cohort of children ( Results: We identified 52 children with RIS-2010 detected at a median age of 15.0 (range 8.1–17.9) years. Mean follow-up time was 4.2 ± 4.9 years. A first clinical neurological event occurred in 18/52 children (34.6%) after a median of 1.7 (range 0.1–17.1) years. Diagnostic indices (95% C.I.) for 2016 vs. 2005 DIS criteria were: sensitivity: 100% (82–100%) vs. 67% (41–87%); specificity: 25% (11–41%) vs. 53% (35–70%); positive predictive value (PPV): 41% (26–57%) vs. 43% (24–63%). PPV for the 2010 DIS criteria was 35% (22–49%). The presence of spinal cord lesions on MRI was the only component independently associated with a first clinical neurological event (HR 3.4, 95% C.I.1.0–11.7; p=0.05). Conclusions: Proposed MAGNIMS 2016 DIS criteria have greater sensitivity, but much lower specificity than 2005 DIS criteria for predicting a first clinical neurologic event in children with RIS-2010. Greater false positive diagnoses using 2016 criteria may generate clinical counseling concerns. Asymptomatic spinal cord lesions on MRI strongly predict a first clinical neurologic event.
