Objective

Background BACKGROUND: It is unclear whether the genetic and environmental risk factors of pediatric MS and NMO overlap.

Design/Methods DESIGN/METHODS: Sera were collected from patients who were diagnosed with NMO by the Pediatric MS Network or donated samples to the Accelerated Cure/Guthy Jackson Biobank. Pediatric MS and neurological control samples were also provided by the Network. Antibodies against EBV (EBNA1 and VCA), HSV-1, and CMV were measured by ELISA. Serum 25(OH)-vitamin D was measured by chemoluminescent immunoassay. HLA-DRB1 status was measured via PCR. The association of herpes virus exposure, HLA-DRB1 status, and vitamin D level with diagnosis was evaluated by logistic regression adjusting for age, gender, race, and ethnicity.

Results RESULTS: Serum and DNA were available from 34 pediatric NMO, 186 pediatric MS/CIS, and 33 pediatric neurological controls. Median age at NMO onset was 11.0 years. Median disease duration at sample collection was 3.61 years. Compared to patients with MS, those with pediatric NMO had a lower frequency of positive DRB1 status (OR 0.180, 95%CI: .035 to 0.927, p=0.040) and HSV-1 exposure (OR 0.147, 95%CI: 0.025 to 0.862, p=0.034). NMO patients were more likely exposed to CMV but less likely to EBV, but neither of these findings reached statistical significance. Analyses of 25(OH) vitamin D association are ongoing.

Conclusions CONCLUSIONS: NMO patients have lower prevalence of HLA-DRB1*15:01 and HSV-1 exposure compared to those with MS but these prevalences are similar to controls. Larger case-control studies are needed to confirm these findings.
