In this episode, Krissy Dilger of SRNA interviewed Dr. Vivien Xie regarding the significance of brain lesions in pediatric MOG antibody disease (MOGAD). Dr. Xie explained the autoimmune nature of MOGAD and the common occurrence of optic neuritis in young patients [00:01:28]. She described her study comparing children with optic neuritis who had brain lesions to those who did not, revealing that brain lesions often did not result in additional symptoms [00:02:41]. The findings suggested that brain lesions didn't significantly impact long-term outcomes, which may provide reassurance for patients with concerning MRI results [00:06:43]. Finally, they discussed the study’s implications for better understanding different phenotypes of MOGAD and improving patient prognosis. Future research directions include more detailed MRI analysis and cognitive outcome assessment [00:12:29]. You can read about this multicenter study here:

Vivien Xie, MD, is a pediatric neurologist and neuroimmunology fellow at Children’s National Hospital and MedStar Georgetown University Hospital. Originally from Baltimore, she earned her undergraduate degree in biology from the University of Maryland, College Park and her medical degree from the University of Maryland School of Medicine. She then completed a child neurology residency at Children’s National Hospital, where she discovered a passion for helping young patients and their families navigate rare and often life-long neuroimmunologic disorders.
Dr. Xie's research interests include pediatric multiple sclerosis and MOG antibody–associated disease, with publications and presentations spanning national and international conferences. She is a committed academic clinician dedicated to advancing clinical trials and research initiatives to improve diagnosis and care for children with rare neuroimmunologic conditions.
