Ask the Expert 1401. Open Q&A on Neuromyelitis Optica Spectrum Disorder (NMOSD)

In SRNA’s Ask the Expert episode moderated by Krissy Dilger, Dr. Elena Grebenciucova described neuromyelitis optica spectrum disorder (NMOSD) symptoms including optic neuritis, transverse myelitis, brainstem syndromes, and intractable hiccups [00:01:05]. She outlined diagnostic evaluation using MRI and correct blood-based antibody testing (preferably cell-based assays), common diagnostic pitfalls, and the need to rule out infections before immunosuppressive treatment [07:08]. Dr. Grebenciucova reviewed urgent relapse management with IV steroids and early plasma exchange, side effects, long-term preventive therapies (FDA-approved and off-label) [14:02]. Finally, she answered community questions on supplements, chronic optic neuritis, rehab appeals, pain/spasticity, pregnancy planning, long-term treatment duration, mental health, seronegative syndromes, follow-up frequency, and recovery expectations [25:22].Elena Grebenciucova, MD completed neurology residency at the University of Chicago in Chicago, Illinois. Dr. Grebenciucova has been interested in autoimmune disorders of the central nervous system, including rare neuroimmune disorders, since medical school. After residency, she completed a neuroimmunology Fellowship under the mentorship of Dr. Brenda Banwell and Joseph Berger at the Perelman School of Medicine of The University of Pennsylvania. Currently she is an assistant professor of Neurology (MS/Neuroimmunology) and neurological infections at Northwestern University in Chicago, Illinois, and she runs the Transverse Myelitis Center there.

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:https://pubmed.ncbi.nlm.nih.gov/41167051/. This work was completed with philanthropic support from the Global Autoimmune Institute and Fighting Fires with Owen.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.00:00 Introduction01:28 Understanding MOG Antibody Disease02:41 Research Motivation and Background05:33 Study Design and Methodology06:43 Key Findings and Implications12:29 Future Research Directions14:10 Conclusion and Acknowledgements
