About

Background:

Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about MS s stages and follow them until a person s death.

Objective:

To understand how the physical and clinical signs of MS relate to its changes over time.

Eligibility:

Adults age 18 or older with MS or a disease of the brain and spinal cord that may act like MS.

Design:

Participants will have a medical history and a complete neurological exam. They may have timed tests of neurological function, such as a 25-foot walk and a 9-hole peg test.

Participants will have multi-day visits about once a year.

Participants will have blood drawn.

Participants may have a brain magnetic resonance imaging (MRI) scan. They may also have an MRI of the spinal cord. They may get a contrast agent (dye) injected into a tube in an arm vein. During the MRI, participants will lie on a table that slides in and out of a metal cylinder.

Participants will have the thickness of their retina measured using optical coherence tomography. A camera on top of a table uses lasers. Participants will look through a lens and follow instructions. Eye drops may be used to dilate the pupils.

Participants will chew on a piece of sterile cotton for 1 minute to collect saliva.

Participants agree to have an autopsy at the time of their death and to donate some of their organs to research, such as the brain and spinal cord.

Full description

Objective:

The goal of this protocol is to understand how the pathology of multiple sclerosis (MS) relates to its evolution over time as observed through neuroradiological, clinical, and biological data collection in vivo.

Study population:

This study will enroll up to 150 individuals with MS, targeting 50 study completers, across various ages and stages of the disease, as well as 50 appropriate disease and non-neurological control participants, for a total of 200 participants.

Design:

This is a longitudinal cohort study in which participants will be seen approximately annually at the NIH Clinical Center. Most visits will extend over several days. Participants will receive ongoing care by their outside clinician. They may also concurrently participate in additional research protocols at the NIH or elsewhere, and data may be shared between those protocols and the current one. At the time of death, the central nervous system (CNS) (brain, spinal cord, retinas, and cerebrospinal fluid), as well as lymph nodes and possibly other lymphoid tissue, will be harvested.

This is a multi-site study with Johns Hopkins University. Some analysis of identifiable data will be conducted at Johns Hopkins University JHU under a reliance agreement. Patients will not be consented to the study or participate in study interventions/procedures at JHU.

Outcome measures:

Outcome measures include data derived from magnetic resonance imaging (MRI) of the brain and spinal cord, optical coherence tomography (OCT) of the retinas, clinical examination, and disability scales; radiological and pathological examination of CNS tissue; and the correlation between in vivo and postmortem measures. Particular attention will be paid to the extent to which longitudinal in vivo changes predict postmortem findings.

Enrollment: 200 estimated patients

Sex: All

Ages: 18 to 120 years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

• INCLUSION CRITERIA:
• Diagnosis of MS according to consensus criteria at the time of enrollment OR diagnosis of a disease that shares clinical, imaging, or biological features with MS OR individuals without known CNS disease.
• Age greater than or equal to 18.
• Able to participate in study procedures and provide high-quality clinical research data (for example, prior MRI scans show ability to tolerate the MRI scan with minimal motion artifact).
• Willing to return to NIH for follow-up visits approximately annually (or every 5 years for non-CNS controls) until the time of autopsy. Note: participants who become too sick to return to NIH will not be removed from the study.
• Willing to undergo autopsy with donation of at least the brain, spinal cord, and retinas.
• Able to provide informed consent at the time of initial study enrollment and willing to appoint a Durable Power of Attorney (DPA) if an advanced directive is not already in place.
• Except for non-CNS controls, simultaneously participating in another screening or natural history protocol within the NINDS Neuroimmunology Clinic at the time of study entry.
• Eligible NIH employees and staff may participate.

EXCLUSION CRITERIA:

Unwilling to allow sharing and/or use in future studies of coded samples and data that are collected for this study.

Trial design

200 participants in 3 patient groups

Individuals without known CNS disease

Description:

Family members of patient participants

Patient controls

Description:

a target population of 50 patient controls will also be enrolled. These individuals will have diseases that share clinical, imaging, or biological features with MS.

Patients with multiple sclerosis

Description:

Up to 150 adults (age \>= 18) with MS, diagnosed by applicable consensus criteria, and by the best judgment of the investigators, at the time of enrollment.
