| Brief Title † | Magnetic Resonance Imaging (MRI) to Evaluate Activity of Multiple Sclerosis (MS) | ||||||||
| Official Title † | Evaluation of Progression in Multiple Sclerosis by Magnetic Resonance Imaging (MRI) | ||||||||
| Brief Summary | Studies performed under 89-N-0045 are designed to examine the natural history of multiple sclerosis (MS) using MRI and immunological measures. In addition to studying the natural history of untreated patients, the natural history of patients receiving approved disease-modifying therapies of MS will be examined. In both cohorts of patients levels of disease activity on MRI will be compared with immunological characteristics in order to help identify disease mechanism. Patients with either definite MS (based either on clinical or combined clinical and MRI criteria) or with an initial presentation of neurological dysfunction consistent with MS will be studied longitudinally by MRI. Disease activity on MRI will be assessed using several MRI measures of disease activity including the number of contrast enhancing lesions, the overall burden of disease, brain atrophy and measures to assess axonal damage. Patients will be assessed clinically and correlations between immunological and genetic factors and disease activity as seen clinically or by MRI will be studied. A second cohort of patients starting the use of approved therapy will also be examined. Patients referred to NIH prior to beginning approved therapy will be assessed with a series of three monthly MRIs to determine the level of pretreatment disease activity. After beginning approved therapy under the direction of their private physician, patients will be followed similarly to the natural history cohort. Immunological and genetic findings will be accessed before and during therapy in order to help establish the mechanisms of action of the therapies and to identify mechanisms accounting for either a response or lack of response to therapy. Part of the collected samples willl be cryopreserved to provide respository for further studies focusing on detection of biomarkers indicative of disease state, disease stage or repsonse to therapies. Additionally, a cohort of normal volunteers will be studied. The studies in the normal volunteers will be used to establish the most appropriate imaging sequences for studying normal white matter in MS patients using magnetization transfer (MT) imaging sequences for studying normal white matter in MS patients using magnetization transfer (MT) imaging and to provide normative immunological measures. |

Disease activity on MRI will be assessed using several MRI measures of disease activity including the number of contrast enhancing lesions, the overall burden of disease, brain atrophy and measures to assess axonal damage. Patients will be assessed clinically and with neurophysiologic tests and correlations between immunological and genetic factors and disease activity as seen clinically or by MRI will be studied. A second cohort of patients starting the use of approved disease-modifying therapies will also be examined. Patients referred to NIH prior to beginning approved therapy will be assessed with a series of three monthly MRIs to determine the level of pretreatment disease activity.
