Introduction
What Is Multiple Sclerosis?
• Chronic progressive autoimmune disease
• Immune system attacks the myelin sheath on nerve fibers in the
brain and spinal cord (CNS)
• May lead to focal areas of damage, axon injury, axon
transection, neurodegeneration, and subsequent scar or plaque
formation

What the Primary Care Clinician
Needs to Know About MS
• Common presenting symptoms of demyelinating
disease
– For example, what is CIS, optic neuritis, brain stem
syndrome, etc
• How the diagnosis of MS is made
• Early symptoms that trigger need to refer patient to
neurologist
• How to classify MS
• How to manage treatment of MS/monitor MS patients
(and what to monitor for)
• How to manage treatment side effects
PIK NW Regional Survey (N = 50)
Barriers to Diagnosis and Treatment
• Lack of clinician knowledge about MS, its diagnosis,
and treatments
• Infrequency of MS in primary care populations
• Lack of time, especially since patients have other
complaints to address
• Absence of screening tools
• Financial/insurance-related obstacles
• Side effects of treatment
• Patients’ psychosocial status and lack of support
• Poor adherence to treatment

Evidence for Environmental
Basis of MS
• No evidence of MS prior to 1822 (~ onset of industrial revolution
in Europe)
• Change in the gender ratio over time
• These changes (eg, gender ratio, increasing incidence) took
place over ~ 30 years (1–2 generations)—too fast for a genetics
cause
• Increased incidence of MS in many regions (especially in
women)
– When individuals migrate before age 15 from a region of high MS
prevalence to one of low prevalence (or vice versa), they seem to
adopt a prevalence similar to that of the region to which they moved
– When they make the same move after age 15, they seem to retain
the risk of the region from which they moved
Multiple Sclerosis
What Are the Environmental Factors?
• Many environmental factors have been
proposed
• Two currently popular candidates for
involvement in MS pathogenesis are:
– Epstein-Barr virus (EBV) infection
– Vitamin D deficiency (sunlight exposure)
– Cigarette smoking
• These are hypotheses—not proven facts!
– Either, neither, or both may be correct
Evidence for EBV
• Indirect evidence
– Late EBV infection is associated with MS
– Symptomatic mononucleosis is associated with MS
• Direct evidence
– 10 out of 12 studies found a significantly higher rate of EBV
positivity in MS patients than in controls1-12
– When data from these 12 trials are combined
(N = 4155), EBV positivity is found in 99.5% of MS patients
vs 94.2% of controls (P <10-23)

Direct Evidence for Vitamin D
• >185,000 women interviewed about their diet: Those in
highest quintile of vitamin D consumption had significantly
less new-onset MS compared with lowest quintile1
• Study of MS patients and controls from Tasmania found
significant negative association between total sun
exposure during childhood (especially in those 6–10 years
old) and adolescence and the subsequent development of
MS2,3
• Evaluation of stored serum samples from 257 MS patients
and 514 matched controls (US Military) showed the risk of
MS was significantly decreased in those with increased
serum vitamin D3 levels4

Cigarette Smoking and MS
• Several cohort and case-control studies have suggested
that cigarette smoking nearly doubles the risk of MS1-3
– Risk increases with cumulative smoking “dose”2
• Parental smoking also doubles the risk of MS in children
who are passively exposed to the smoke4
• Smokeless tobacco has not been found to increase MS
risk1,2
– Implies that non-nicotinic components of cigarette
smoke are responsible

Risk Factors for MS
Summary
• MS is caused by a complex interaction of genetic and
environmental factors
– In someone with an affected identical twin, risk of MS is
25%, suggesting that genetics play a role in susceptibility but
are not the complete story
• Vitamin D insufficiency, EBV infection, and cigarette
smoking have shown possible links to MS
– This research is thought-provoking, but these factors have
not been definitely proven as causes of MS
Pathophysiology of MS
Pathophysiology of MS
• Acute Inflammation
• Neuronal Degeneration
Relapses
Disability
Immune Dysregulation in MS
T Cells
• T cells normally recognize specific antigens
– CD8+ T cells destroy infected cells
– CD4+ T cells release cytokines that mediate inflammatory
and anti-inflammatory responses
• T cells reactive to myelin are found in MS lesions,
blood, and cerebrospinal fluid
– CD8+ T cells transect axons, induce oligodendrocyte death,
promote vascular permeability1
– There is a cytokine imbalance in MS, favoring secretion of
inflammatory (Th1) cytokines
– T cells that normally regulate immune function have reduced
activity in MS2

Immune Dysregulation in MS
B Cells
• In some MS patients, ectopic lymphoid
follicles have been found in the meninges1
• Mechanisms of B cells in MS may include:
– Antimyelin antibody production
– Antigen presentation to autoreactive T cells
– Proinflammatory cytokine production
1. Uccelli A, et al. Trends Immunol. 2005;26:254-259.
Immune Dysregulation in MS
Other Involved Cells
• Natural killer (NK) cells
– May play opposing roles as both regulators and inducers of disease
relative to cytokine environment and cell:cell contact
– NK cell function may be lost during clinical relapse
• Monocytes
– Secrete IL-6 (promotes B cell growth) and IL-2 (aids differentiation
of Th1 cells)
• Macrophages
– Phagocytic activity may contribute to demyelination
• Microglia
– Specialized macrophages in the CNS, also may contribute to T cell
activation
Neurodegeneration
• Loss of axons is the main cause of permanent disability in MS
• Axonal damage has been shown to occur in acute inflammatory
plaques1 and can lead to brain atrophy
– Occurs in white and gray matter
– May also produce cognitive impairment
• Axonal damage could be the result of
– Cumulative inflammatory damage over time
– A parallel degenerative process related to loss of trophic support or
an independent axonal degeneration2
• Can effective immune therapy early in MS prevent worsening
disability?
1. Trapp BD, et al. N Engl J Med. 1998;338:278-285. 2. Trapp BD. Neuroscientist. 1999;5:48-57.
Conclusions
• Pathogenesis of MS involves complex interactions between
genetic and environmental factors
– Multiple genes are involved
– Vitamin D deficiency, EBV infection, and cigarette smoking are
environmental candidates
• MS incidence has increased over the past 30 years due to a
change in environmental exposure
• MS pathogenesis involves multiple immune cell types (T cells,
B cells, NK cells, others)
• Along with chronic inflammation, MS pathogenesis involves
axonal loss
– Neurodegeneration is the major source of disability in MS
Challenges in Diagnosing MS
What Is an MS “Attack”?
• Neurologic symptoms lasting ≥24 hours but
generally longer
– Not explained by other conditions
– Do not represent recurrent symptoms in
association with increased body temperature or
infection (pseudoexacerbations)
• To be considered separate attacks, the
interval between episodes must be ≥30 days
McDonald WI, et al. Ann Neurol. 2001;50:121-127.
Clinical Presentation
• MS symptoms vary widely among individual patients
• Numbness, tingling, or weakness in the limbs
– Usually unilateral or only lower half of body
• Tremor, spasticity, incoordination, unsteady gait, imbalance
• Vision loss (usually unilateral), pain with eye movement, double
vision
• Fatigue, dizziness, cognitive impairment, unstable mood
• Urinary and bowel incontinence or frequency
• Increased body temperature may trigger or worsen symptoms

Disease Course
• After initial episode, MS patients typically follow a
chronic pattern of acute neurologic symptoms
(relapses) followed by periods of stability (remission)
• Timing, progression, duration, severity, and specific
symptoms are variable and unpredictable
• Typically 2 to 3 relapses per year in untreated
patients; treated patients have significantly fewer
relapses
• Some symptoms may be ongoing/chronic; these do
not represent relapse
• Long-term deficits range from mild to severe
Diagnosis of MS
• Clinically definite MS must meet criteria for1
– Dissemination in space
– Dissemination in time
• A single episode of MS-like symptoms (clinically
isolated syndrome [CIS]) will not meet these criteria
– But if MS is likely based on MRI, it still should be treated like
MS
• Delaying treatment may be missing an important window of
opportunity to delay the onset of irreversible disability
– Requires close monitoring over time to confirm diagnosis

Revised McDonald Criteria
• At least 3 of the following on MRIa:
– ≥1 Gd-enhancing brain or spinal cord lesion or ≥9
T2 hyperintense brain and/or spinal cord lesions of
≥3 mm in size if none of the lesions are Gdenhancing
– ≥1 brain infratentorial lesion or spinal cord lesion
≥3 mm in size
– ≥1 juxtacortical lesion ≥3 mm in size
– ≥3 periventricular lesions ≥3 mm in size
aTo
meet criteria for dissemination in space
Polman CH, et al. Ann Neurol. 2005;58:840-846.
Revised McDonald Criteria
• At least 1 of the followinga
– A 2nd clinical episode
– A Gd-enhancing lesion detected ≥3 months after onset of
initial clinical event
• Located at a site different from the one corresponding to the
initial event
– A new T2 lesion detected any time after a reference scan
that was performed at least 30 days after the onset of an
initial clinical event
• Thus, it is not always necessary to wait for 2 attacks
to diagnose MS. A first attack plus changes on MRI
may be enough
aTo
meet criteria for dissemination in time

Spinal Cord
CMSC MRI Protocol 2009
• Obtain brain MRI at baseline, with contrast
• Obtain spinal cord MRI if symptoms pertaining to
spinal cord lesions or no evidence of disease activity
in brain
• Repeat scan if:
– Unexpected clinical worsening
– Need to re-evaluate diagnosis
– Starting or modifying treatment
• Consider serial MRI every 1-2 years to evaluate
subclinical activity
Consortium of Multiple Sclerosis Centers.
http://www.mscare.org/cmsc/images/pdf/mriprotocol2009.pdf
Performing Serial MRIs
for Follow-up
• A standardized protocol using consistent technology
and protocols is essential to serial MRI interpretation
–
–
–
–
–
Same magnet strength and slice thickness
Same sequence acquisition
Same patient positioning
Same plane
Section selection should match prior MRIs as closely as
possible
• Radiologists should follow the updated CMSC
protocol1 for standardizing MRIs in clinical MS
applications

MRI Correlates Poorly With
Clinical Outcomes
• T2 lesion volume at a single point in time correlates
weakly with clinical disability and is a measure of past
attack frequency1
– Change in lesion volume over time may be a better
correlate2
• T1-weighted black holes are a better but still
imperfect correlate of disability3
• Brain atrophy is a measure of neurodegeneration that
may predict disability4

Brain. 2002;125:1676-1695.
Why MRI Correlates Poorly
with MS Disability
• MRI cannot determine extent/nature of tissue
damage
• Location of lesion influences its clinical manifestation
• MRI cannot distinguish between demyelinated and
remyelinated lesions
• MRI cannot detect gray matter lesions or diffuse
damage in normal-appearing white matter
• Plasticity of CNS may lead to compensatory use of
alternative neural circuit to circumvent damaged
areas
Emerging MRI Technologies

Measures of CNS atrophy
Magnetization transfer imaging
Proton magnetic resonance spectroscopy
Diffusion tensor imaging
Susceptibility weighted imaging
Other Diagnostic Tools for MS
CSF Analysis
• Positive if oligoclonal IgG bands present but absent
from corresponding serum sample or IgG index is
elevated
– Sensitive but not specific: other causes of CNS inflammation
can yield similar findings
• Lymphocytic pleocytosis is rarely >50/mm3
• Protein levels rarely exceed 100 mg/dL
• Elevated myelin basic protein is not pathognomonic
for MS
Other Diagnostic Tools for MS
Visual Evoked Potentials (VEPs)
• Provides evidence of a lesion associated with
visual pathways
• Positive if shows delayed but well-preserved
wave forms
– Abnormal VEP is not specific for MS
• Can help establish dissemination in space

Neuromyelitis Optica (NMO)
• Syndrome of aggressive inflammatory demyelination afflicting
the optic nerves and spinal cord1, often associated with severe
disability
• Associated with infections and collagen vascular diseases1
– Idiopathic form is considered a variant of MS
• Modern case series indicate that NMO is characterized by1
– Recurrent attacks of optic neuritis and acute transverse myelitis
– Multisegmental spinal cord lesion >3 vertebral segments
– Initial brain MRI that is often (but not always) normal
• The NMO-IgG antibody recognizes aquaporin-4 (AQP4),2 a
water channel expressed on astrocytes
– Anti-AQP4 antibody is 73% sensitive and 91% specific for NMO3
– Blood testing is available at Mayo Medical Laboratories4

Conclusions
• Diagnosis of MS is based on a combination of clinical
and radiologic factors
– MRI should be performed according to CMSC standardized
protocol
• Revised McDonald criteria are the gold standard for
diagnosis
• High-risk CIS should be treated the same as clinically
definite MS
• Clinical variants and red flags should be taken into
account in formulating differential diagnosis
Achieving Therapeutic Goals
with Current Treatments
Therapeutic Goals in MS
• In the absence of a cure for MS, current goals of
disease modifying therapy are to
– Prevent disability
– Prevent relapses
– Prevent development of new or enhancing lesions on MRI
• Additional goals in the management of MS are to
– Relieve symptoms
– Maintain well-being
– Optimize quality of life
Treating Acute Relapse
• IV corticosteroids = standard of care
– Methylprednisolone 500 to 1000 mg/d IV for 3 to
5 days
• May be followed by oral steroid taper
• High-dose oral steroids may be acceptable
alternative
– Phase III randomized OMEGA trial currently
comparing oral and IV steroids
• Plasmapheresis and IVIG for refractory
relapse

formulations and glatiramer acetate probably
all offer comparable efficacy
Side Effects of Interferons
• Side effects include flu-like symptoms, injection site
reactions/necrosis (SC), liver enzyme elevations,
lymphopenia, depression
• Pregnancy category C
• Warnings: depression/suicide, decreased peripheral
blood counts, hepatic injury, seizures,
cardiomyopathy/CHF, autoimmune disease
• Laboratory tests: periodic CBC with differential, liver
function profile, thyroid function

Side Effect Management Tips
Side Effect
Management
Flu-like symptoms
NSAIDs (eg, naproxen 500 mg 1 h before injection + 12 h
later); IFN administration before bedtime; for patients on
IFN beta-1a IM, prednisone 10 mg on day of injection;
switch to glatiramer acetate
Injection-site
reactions and
injection-site pain
Rotate injection sites; administer injection without the
autoinjector; topical anesthetics; application of ice before
injecting; ensure proper product preparation including
warming to room temperature
Difficulty selfinjecting
Have partner administer injection; if “click” of autoinjector
induces anxiety, administer without the autoinjector; call
company nurse for retraining; home health agency might
administer IFN beta-1a IM; switch to a therapy with less
frequent injections

Rationale for Early Treatment
• Time is ticking…
• What is lost by delaying early therapy is
not regained by starting later
Treating CIS
• Treating CIS vs waiting until patient has
clinically definite MS (CDMS)

–
Decrease progression to CDMS
Decrease rate of disability progression
Reduced lesion load on MRI
Fewer and less severe relapses
Most clinicians advocate early treatment BUT not
all CIS will develop MS

Second-Line MS Therapies
Natalizumab
• Inhibits cell adhesion and leukocyte migration across BBB
• AFFIRM trial1 of natalizumab vs placebo in RRMS
– 42% reduction in risk of sustained progression of disability in 2
years (P <.001)
– 68% reduction in clinical relapse at 1 year (P <.001)
– 83% reduction in new or enlarging T2 lesions over 2 years (P
<.001)
– 92% reduction in Gd-enhancing lesions at 1 and 2 years
(P <.001)
1. Polman CH, et al. N Engl J Med. 2006;354:899-910.
Second-Line Therapies
Natalizumab
• FDA approved for relapsing MS
• Due to risk of PML, natalizumab is generally reserved for
patients who have not responded to or tolerated alternate
therapies
– PML (JC virus of brain) leads to severe disability or death; no
known treatment
– Available only through very restricted distribution program (TOUCH
Prescribing Program)
• Other warnings: hepatotoxicity, hypersensitivity reactions,
immunosuppression
Tysabri [package insert]. Cambridge, MA: Biogen Idec; 2009.
Mitoxantrone
• Antineoplastic in anthracenedione class
• FDA approved for SPMS, PRMS, worsening RRMS
• Causes cross-links and strand breaks in DNA; inhibits B cell,
T cell, and macrophage proliferation
• Due to serious side effects, reserve for patients with rapidly
advancing MS despite other disease-modifying therapies
–
–
–
–
Cardiomyopathy (LVEF decreased in up to 18%; CHF)
Secondary acute myelogenous leukemia (0.25%)
Elevated liver enzyme and glucose levels
Requires frequent monitoring (CBC, liver function tests, LVEF,
ECG)
• Administration should be performed by an oncologist
Novantrone [package insert]. Rockland, MA: EMD Serono, and Melville, NY: OSI Pharmaceuticals; 2009.
Starting an MS Patient on a
Disease-Modifying Agent
• Obtain starter kit from local representative
• Complete physician portion of Enrollment Form and have
patient complete the patient portion
• Upon receipt of form, company will verify patient’s
insurance benefits
• Company will supply medication and send nurse to the
patient’s home for training on self-injection and proper
needle disposal
• Titrate interferon dose as indicated on the Enrollment
Form
Monitoring
• Follow up 4−6 weeks after initiating therapy
– Assess injection technique and tolerability
• If stable on therapy, re-evaluate every 3−6 months
• Laboratory testing for interferon
– CBC and liver enzyme levels 4–6 weeks after starting
treatment,
3 months later, then every 6 months
• No laboratory testing needed for glatiramer acetate
• Continue on therapy indefinitely unless clear lack of
benefit, intolerable side effects, or better treatment
becomes available

Rio J, et al. Mult Scler. 2005;11:306-309.
Assess Adherence by Asking
• Patients typically will not tell you they have been
nonadherent if you do not ask
• Ask in nonjudgmental manner that assumes they
have missed some doses
– For example: How many injections do you think you have
missed in the past 2 months?
• Being asked helps motivate patients to adhere
• Assess barriers by asking: What prevents you from
taking your medication?
– NOT: Why aren’t you taking it? (Avoid casting blame)
Address Barriers to Adherence
•
•
•
•
•
•
•
•
•
•
Difficulty self injecting
Adverse events
Unrealistic expectations of therapy (symptom relief)
Lack of acceptance of MS diagnosis and need for treatment
Financial considerations
“Treatment fatigue”
Depression
Cognitive deficits
Impairment in fine motor skills
Changes to family and support circumstances
Suboptimal Treatment
Response
• Worsening clinical status
• Radiologic changes (MRI)
– New Gd enhancement and/or new or enlarging T2 lesions
are signs of disease activity
• No consensus as to when such findings warrant change in
treatment
• Interpret in context of whole clinical picture
• If found on repeat scans, even if patient is clinically stable,
probably warrants change in therapy
– Remember: comparison of serial MRI scans requires
consistent use of standardized MRI protocol (CMSC
protocol)
Suboptimal Response
Potential Causes
• Nonadherence
• Pharmacogenomics: responsiveness to IFN β
related to genetics1
• Variable pathologies with differing responses to
immune therapies
• NAbs
• MS subtype (disease modifying agents do not
work in PPMS)
1. Byun E, et al. Arch Neurol. 2008;65:337-344.
Refer or Consult a Neurologist
• When diagnosis is in doubt
• If a consult is desired regarding selection of
initial therapy
• For patients with poor response or toleration
of first-line therapies
• When considering use of natalizumab or
mitoxantrone
Conclusions
• Current MS therapies can reduce relapse rates and
disability progression
– Interferon beta or glatiramer acetate is first line
• It is best to start treatment as early as possible
• Patient education is essential when starting treatment
– Rationale for treatment, injection technique, side effect
management, importance of adherence
• After starting treatment, monitor for response,
tolerability, and adherence
Emerging MS Therapies
Limitations of Current
Therapies
• All are only partially effective
• All are injectable or IV and have side effects
• Risks vs benefits
– Existing therapies have advantage of long-term
safety data
• Difficulty predicting therapeutic response
• Goal: Individualized, more effective, safe
medication(s) that are easier to administer
Two Oral Therapies Have
Completed Phase III Studies
• Fingolimod
• Cladribine
• 3 important questions to ask1
– How do they compare with current therapies?
– Are all of the long-term safety issues known?
– What do they tell us about MS and our treatment
goals?
1. Carroll WM. N Engl J Med. 2010;362:456-458.
Fingolimod
• Modulates sphingosine-1-phosphate receptors
– Receptors play a role in egress of lymphocytes out of lymph
nodes
• Fingolimod sequesters lymphocytes in lymph nodes
• Fingolimod crosses blood-brain barrier and may have
neuroprotective properties
• Dosing: once-daily pill
• Status: 2 phase III trials completed; pending FDA
review

Do We Have the Answers to
the
Three Questions?
• Fingolimod and cladribine are likely to be at least as effective as
available treatments
– Fingolimod > IFN beta-1a IM in TRANSFORMS
– IFN beta-1a IM was the least effective of available therapies in prior
head-to-head trials
• Fingolimod and cladribine may have greater safety issues
– Severe herpes infections, malignancies, lymphocytopenia (both
fingolimod and cladribine)
– Macular edema, bradycardia/AV block (fingolimod)
– Higher discontinuation rates than available therapies
• It is not yet clear whether these therapies can prevent immunemediated injury
Carroll WM. N Engl J Med. 2010;362:456-458.
Additional Oral Small-Molecule
MS Therapies in Late-Stage
Development

• Teriflunomide
• Laquinimod
Emerging Monoclonal
Antibodies
•
•
•
•
Rituximab
Ocrelizumab

Conclusions
• Oral therapies for MS may soon be available
• Phase III studies have been completed for fingolimod and
oral cladribine
– Possibly more effective at reducing relapse rates
compared with current therapies, but not clear that they
are any better at preventing disability
– Some serious adverse events have been observed
 Requires patient understanding of risks and need
for close monitoring
• Other small molecules and monoclonal antibodies are in
late-stage development for MS
Symptom Management

Conclusions
• Managing MS means thinking about more than just preventing
relapse and new lesions
• It is important to address other symptoms that interfere with
QOL
• Symptoms need to be recognized in order to treat
• Address 1 or 2 symptoms per visit—prioritize
• Through counseling and treatment, most symptoms can at least
be reduced
• Refer to specialists as needed for optimized symptom control
• Expect that many symptoms will never be fully controlled
The Dialogue of MS
in Primary Care
Communicating with Patients
and Peers
• There are many resources for clinicians and patients
available online
• Social media sites offer resources as well as an
opportunity to connect with others
• Some of the information your patients receive over
the Internet and via social media sites is more
accurate than others
– Know what is available
– Recommend reputable sites
– Ask what they are using
