Predictors of a Relapsing Course in Myelin Oligodendrocyte Glycoprotein Antibody-associated Disease
Multiple Sclerosis
S7 - Multiple Sclerosis: Special Populations and Non-MS CNS Neuroinflammatory Disease (4:54 PM-5:06 PM)
008
Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a recently identified demyelinating disorder, and children represent about 50% of all cases. Almost half of the patients experience relapses, but very few studies have evaluated predictors of relapse risk, challenging clinical management. 

The study aimed to identify factors at MOGAD onset that are associated with a multiphasic course.

Prospectively collected data from pediatric patients with MOGAD seen by the US Network of Pediatric MS Centers were leveraged. Univariable and multivariable models were used to predict recurrent disease after adjusting for confounders.
We identified 326 MOGAD cases (mean age at first event 8.9 years (SD 4.3), 57% female, 77% White, 74% non-Hispanic), and 46% relapsed during a mean follow-up of 3.9 years (SD 4.1). In the adjusted multivariable model, female sex (HR 1.64, 95% CI 1.16-2.33, p=0.005) and Hispanic/Latino ethnicity (HR 1.65, 95% CI 1.11-2.45, p=0.012) were associated with a higher risk of relapsing MOGAD. Non-Whites had a higher estimated risk of relapse (HR 1.47, 95% CI 0.98-2.20, p=0.063). Maintenance treatment initiated before a second event with an anti-CD20 agent (HR 0.25, 95% CI 0.07-0.92, p=0.037) or intravenous immunoglobulin (IVIG) (HR 0.35, 95% CI 0.14-0.88, p=0.026) was associated with lower risk of a second event in multivariable analyses. Conversely, maintenance steroids were associated with a higher estimated relapse risk (HR 1.76, 95% CI 0.90-3.45, p=0.097). Other demographic, clinical, biological, and MRI characteristics at onset did not show significant associations with the risk of having a relapse.

Sex and ethnicity, and potentially race are associated with relapsing MOGAD. Use of anti-CD20 or IVIG therapy shortly after onset is associated with a lower risk of second event. Preventive treatment after a first event could be considered in those with a higher relapse risk.
