Thematic Studies of Multiple Sclerosis and Related Diseases
Background:
- Magnetic resonance imaging (MRI) has been used for decades to help diagnose and monitor
neurological disorders like multiple sclerosis (MS). Researchers want to improve how MRI
pictures are taken. They also want to learn more about using newer MRIs with stronger magnets
to get better pictures than standard MRIs provide.
Objectives:
- To collect data that will help researchers better understand MS and related diseases.
Eligibility:
- Adults 18 and older with MS or MRI findings that appear similar to MS, or with other
neurological diseases that may look or act like MS.
- Healthy adult volunteers.
Design:
- Participants will be screened with a review of their medical records.
- Participants will have a baseline visit. It will include a physical exam, medical
history, and neurological exam. They may have blood tests.
- The study will last indefinitely.
- Participants may have MRIs. Some MRIs may include a contrast dye. For this, a needle
will be used to guide a thin plastic tube into an arm vein.
- Participants may have up to 2 lumbar punctures per year. Skin will be numbed and a
needle inserted between back bones will remove fluid.
- Participants may give saliva samples and have an eye exam.
- Participants may have evoked potential tests. These measure how the nervous system
responds to different types of stimulation. Participants may sit in front of a TV and
watch pictures on the screen. Or they may wear earphones that make a clicking noise or
static. Or they may get a small electrical shock that may tingle and cause a hand or
foot twitch.
- Participants may have tests of strength, spasticity, sensations, balance, and/or
walking.

Objectives.
The goals of this protocol are to study the pathophysiology of multiple sclerosis (MS),
primarily through small studies that utilize magnetic resonance imaging (MRI), and to
correlate the results with clinical and biological measures. The protocol includes only
techniques with minimal risk (standard and quantitative clinical evaluation, MRI, blood
draws, saliva testing, urine and stool collection, visual evoked potentials, ophthalmologic
evaluation) or more-than-minimal risk (injection of approved gadolinium-based contrast
agents, lumbar punctures) that are appropriate and common in this study population. Under
this protocol, we will conduct:
- Pilot substudies. These studies are exploratory and hypothesis generating. Once
sufficient data are collected to justify a hypothesis-driven study and a formal power
analysis, further work will continue under either a dedicated protocol or, if
appropriate, a hypothesis-testing substudy. There are no enrollment limitations for
pilot substudies.
- Hypothesis-testing substudy. These studies have a specific hypothesis that can be tested
with at most 6 participants per arm. If additional participants are required, a memo
will be sent to the Protocol Review Committee (PIRC) and its statistical reviewer to
request review of a hypothesis-testing substudy for possible additional enrollment.The
memo will also be forwarded to the IRB.
- Individual patient substudies. These studies seek to increase knowledge of a disease
process or to assist in the diagnosis of an individual patient.
- Technique development substudies. These studies will lay the groundwork for new
experimental paradigms, using the methods approved under this protocol, which can be
further tested in the substudies listed above.
- Training of investigators. These studies will be done to train new investigators in
techniques relevant to the studies under this protocol.
Study Population
Three groups of study participants will be enrolled:
- MS patients. Participants with definite, probable, or possible MS.
- Patient controls. Participants with diseases that share features with MS.
- Healthy volunteers.
Design
We will design small substudies as ideas arise in the course of our work that are pertinent
to the theme of the pathophysiology of MS (or of diseases that share features with MS). If a
hypothesis testing sub-study leads to results of interest and if a larger population is
necessary to reach statistical significance, a separate protocol will be submitted with a
priori hypotheses, specific study design and power analysis adapted from the pilot or
exploratory substudies performed in the present protocol.
Outcome Measures
These will include MRI, clinical, and biological outcome measures consistent with the
objectives of the study and its investigators. Imaging measures will focus on features
related to the central nervous system (CNS), particularly focal lesions. Clinical measures
will include standard and established MS disability scales as well as quantitative measures
related to function. Biological measures will include genotype, gene expression, proteomics,
virological studies, and immunological profiling.
