Outpatient follow-up of disease-modifying therapies (DMTs) used to reduce relapses and slow disability progression in MS, a demyelinating disease of the central nervous system.
Indication
- Diagnosis or suspicion of relapsing-remitting MS (RRMS)
- Secondary progressive (SPMS) and primary progressive (PPMS) MS
- Follow-up of clinically isolated syndrome (CIS)
- New demyelinating lesions on MRI
- Relapse (flare) management and steroid therapy
- DMT selection, monitoring of effectiveness, and side-effect surveillance
Preparation
- Bring previous MRI and cerebrospinal fluid (CSF) reports to the visit
- Note the current DMT, dose, and any side effects experienced
- Review of vaccination status (especially before B-cell therapy)
- Inform the physician of any pregnancy plans
How it's performed
- Neurological examination and EDSS (disability) scoring
- Brain and cervical-thoracic spinal cord MRI
- Lumbar puncture for oligoclonal bands when indicated
- First-line DMT: interferon-beta or glatiramer acetate
- Oral DMT options: fingolimod, dimethyl fumarate, teriflunomide
- B-cell-depleting therapy in highly active MS: ocrelizumab
Post-procedure
- Visits every 3-6 months in the first year, then every 6-12 months
- Annual MRI to monitor new lesions and atrophy
- Complete blood count, liver function, and thyroid function tests
- Management of fatigue, bladder, mood, and cognitive symptoms
- Referral to physiotherapy and occupational therapy
Risks
- Interferon: injection-site reactions, flu-like side effects
- Fingolimod: first-dose bradycardia, macular edema
- Dimethyl fumarate: facial flushing, lymphopenia
- Ocrelizumab: infusion reactions, increased infection risk (especially respiratory)
- JC virus-associated PML (especially with natalizumab; rare)
FAQ
Is MS hereditary?
MS is not directly hereditary; however, the risk is slightly higher than in the general population if a family member has MS.
Which DMT is best?
The optimal therapy is individualized based on disease activity, MRI findings, side-effect profile, and pregnancy plans.
How is a relapse (flare) treated?
High-dose intravenous methylprednisolone is typically given for 3-5 days. Plasma exchange may be considered if there is no response.
Is pregnancy possible with MS?
It is possible for most patients; the DMT should be reviewed before conception, and planning should be done together with the physician.
