Risk Factors in Early Multiple Sclerosis
Risk Factors in Early Multiple Sclerosis
The central hypothesis of this protocol is that it is possible, using First Degree Relatives
 (FDRs) of patients with Multiple Sclerosis (MS) and assessing a variety of both known and
 unknown risk factors for MS, to define a risk algorithm for earliest signs of development of
 MS. The plan will be to do an abbreviated brain Magnetic Resonance Imaging (MRI) scan in
 asymptomatic, young FDRs, analyse blood for a variety of immunological, genetic, neuroaxonal
 damage, metabolic, viral serology and other markers, and have FDRs fill out a detailed
 bioscreen questionnaire about lifestyle factors and perform a cognitive screening test. The
 investigators will then compare the results of the various blood/other studies in FDRs with
 and without an MRI showing signs signs concerning for MS, as well as age-and sex-matched
 NON-FDRs who will have blood drawn and fill out the questionnaire. With this preliminary
 cross-sectional study, the investigators hope to begin to identify a risk stratification
 model for those at highest risk of developing MS, ie FDRs, with a long-term goal of
 developing a longitudinal study to increase sensitivity and specificity of the risk model.
Specific Aims, among asymptomatic first degree relatives (FDRs), aged 18-30, of multiple
 sclerosis (MS) patients:

 1. Determine the prevalence of brain MRI lesions disseminated in space (DIS), consistent
 with MS

 2. Gather data on potential risk factors or early signs related to MS development,
 including markers for: genes, immunological function, environmental factors, neuroaxonal
 damage, Vitamin D levels, lipid metabolism, activity levels, mood abnormalities, and
 cognitive function. From this, develop a risk factor score, incorporating all relevant
 potential markers of increased risk of DIS.

 3. To use this pilot, cross-sectional study as a base for development of a long-term,
 longitudinal, multi-center study to determine genetic and environmental risks for
 pre-symptomatic MS

 4. To create and maintain a biobank of specimens for future analysis as other potential
 biomarkers become available.

 Sequences to include

 1. Whole brain T1-weighted images acquired using 3-Dimensional fast spoiled-gradient
 recalled acquisitions (T1-3D-FSPGR) with 1 mm slice thickness and isotropic voxel
 dimensions.

 2. Whole brain 3-Dimensional Double Inversion Recovery (DIR) acquisition with 1.5 mm slice
 thickness.

 3. Whole brain T2-weighted Fluid Attenuated Inversion Recovery (FLAIR ) images with 1 mm
 slice thickness and isotropic voxel dimensions will be combined with

 4. Whole brain T2*-weighted segmented echo-planar imaging (segEPI) images with <=1 mm slice
 thickness and isotropic voxel dimensions to obtain FLAIR* images.

 Blood analysis for:

 1. Single Nucleotide Polymorphism analysis of greater than 200 known mutations associated
 with risk of MS, and do an human leukocyte antigen (HLA) analysis

 2. CD20 on CD4+ cell analysis

 3. B Cell Anergy analysis Lipid levels

 4. Viral serologies (HSV, EBV, CMV, VZV)

 5. Neurofilament Light

 6. Vitamin D levels

 Bioscreen analysis based on that from the Diabetes Autoimmunity Study in the Young (DAISY);
 and to include the Godin Leisure-Time Exercise Questionnaire (GLTEQ), which has been
 validated in both adults and children and a validated dietary/food frequency questionnaire.
 In addition perform a cognitive screen with a Symbol Digit Modality test.

 Blood will also be stored for future potential analysis, including peripheral blood
 mononuclear cells, serum, and Ribonucleic acid (RNA).
