Multiple Sclerosis
Epidemiology
•
Prevalence
–
1.0–1.5 per 1,000 population in the United States
–
~2.5 million cases worldwide
•
Age at onset: 15–45 years
•
70%–75% of cases are women
•
Increasing worldwide prevalence (especially in women)
•
Ethnic origin: predominantly white, but does occur in
other ethnicities as well

Etiology of MS
•
•
Genetics
–
Increased risk in persons who have relatives with MS1-3
–
50–200 susceptibility alleles2,3
–
Strongest association with HLA DRB1*15011-3
Environmental factors, current hypotheses
–
History of Epstein-Barr virus infection1,2,4,5
–
Vitamin D deficiency1,2,6
–
Smoking2 (active7 or passive8)

Pathophysiology of MS
•
Acute inflammation  demyelination/relapses
– Blood-derived lymphocytes and monocytes
– Breakdown of blood-brain barrier
– Edema
– White and grey matter lesions

•
Myelin injury, axonal transection
Neurodegeneration  irreversible disability
– Neuronal loss
– Brain atrophy
Trapp BD, et al. Annu Rev Neurosci. 2008;31:247-269.
Subtypes of MS
•
•
•
•
Relapsing-remitting MS (RRMS)
– Episodes of acute neurologic dysfunction (attacks) ± recovery
– Stable disease between attacks
– Initial diagnosis in ~85% of patients
Primary-progressive MS (PPMS)
– Steady functional decline from onset without attacks
– ~10% of cases
Secondary-progressive MS (SPMS)
– Steady functional decline ± attacks; always follows RRMS
– 50%–80% develop SPMS
Progressive-relapsing MS (PRMS)
– Steady functional decline from onset with occasional attacks
– ~5% of cases

Revised Diagnostic Criteria
Multiple Sclerosis
• Dissemination of lesions in space (DIS)
– ≥1 T2 lesion in ≥2 of 4 CNS areas: periventricular,
juxtacortical, infratentorial, spinal cord*
• Dissemination of lesions in time (DIT)
– ≥2 clinical attacks, or 1 of the following MRI criteria

≥1 new T2 or gadolinium(Gd)-enhancing lesions
not found on baseline scan, irrespective of timing of
baseline scan

Simultaneous presence of asymptomatic
Gd-enhancing and nonenhancing lesions
*If brain stem or spinal cord syndrome, the symptomatic lesions are excluded from criteria and do not
count toward lesion count.

Comparisons of Therapies
Short-Term Outcomes in MS
Establishing Efficacy in MS
• Outcome measures: disease activity
1. Clinical assessment
(eg, attack rate or attack-free status)
2. Radiologic (MRI) assessment
(eg, new T2, Gd+, or combined unique lesions)
• Outcome measures: disease severity
1. Clinical assessment
(eg, confirmed EDSS progression or MSFC)
2. Radiologic (MRI) assessment
(eg, T2 burden, T1 black holes, or atrophy)

Long-Term Follow-Up in RRMS
Glatiramer Acetate
•
•
15-year open-label extension of 2-year phase III trial1
−
Relapses reduced to ~1 every 4 years compared with
1.12 every year at open-label entry
−
57% had improved or stable EDSS scores
−
65% had not progressed to SPMS
Mean 5.8-year follow-up of open-label extension of
18-month trial2
−
Patients taking glatiramer acetate at study onset less
likely to need walking aids vs those starting active
treatment at extension entry (P = .034)

Impact of DMTs on
Cognitive Impairment
•
Likelihood of cognitive impairment was reduced with
–
Early vs delayed IFN beta-1b SC initiation in CIS1
–
Higher-dose IFN beta-1a SC in RRMS2
•
IFN beta-1a IM in relapsing MS improved information
processing and learning/recent memory3
•
Cognitive function was preserved in most patients
taking glatiramer acetate during 10-year open-label
follow-up4

Natalizumab & IRIS
•
IRIS follows PML; in most cases after PE1
–
Due to rapid restoration of immune function after NTZ
clearance2
•
Typical  PML Sx; days to weeks after PE; may require ICU care3
•
Corticosteroids: Strike balance between adequate
immunosuppression while maintaining effective immune response
against JC virus4
–
Methylprednisolone 1 g/d IV for 5 days followed by oral steroids;
repeated courses may be necessary3
–
In case studies, corticosteroids reduced IRIS and improved
EDSS scores in most patients, compared with several deaths3
and worse EDSS scores in patients whose IRIS was untreated5

Choosing the Right Treatment for the
Individual Patient with MS
Initiation of treatment
• Which disease-modifying therapy will fit an
individual patient?
• 1st-line medications vs 2nd-line
• Ability to self-inject – SQ/IM vs oral/IV
• Lifestyle issues
• Career/family roles
• Planning pregnancy
• Planning trip? Vaccines
Decision Making
•
•
•
•
•
•
•
•
Discussion of pros and cons with patients
Partnership with patients and families
Possible use of consent form/contract
Future plans and therapies
Long-term effects of certain medications
Combination of therapies
Safety of medications
Pregnancy
Adherence vs Compliance
•
Compliance implies giving in to a request, wish, or
demand; it implies a subordinate position to healthcare
professionals
Versus
•
Adherence is voluntary, active collaborative involvement
of the patient in a mutually acceptable course of behavior
leading to a desired outcome
Adherence to Therapy
Although it is felt to be important
•
Adherence is difficult
–
•
Nonadherence estimates are about 50%–70%; this is true
for many chronic diseases
Many reasons offered as to why
–
Perception that drug is not working
–
Continued MS symptoms
–
Side effects
–
Insurance coverage
Barriers to Adherence
•
Lifestyle issues
•
Cultural considerations and healthcare literacy
•
Fear of injections
•
Concerns about adverse effects, including injection
site reactions that can affect lifestyles
•
Perceived benefits
•
Lack of an effective support system
•
Depression
•
Cost
Barriers to Adherence
•
•
•
•
Progression of disease – hopelessness
Physical impairments – visual disturbances, tremor,
weakness
Absence of symptoms
Fatigue – too tired to inject
Uncover Injection Barriers
•
What is your schedule for injections?
•
How many injection sites/areas do you use in
1 week?
•
How many injections did you miss in the past month?
•
What were your reasons for missing these injections? Was it
because of site reactions, etc?
•
Can you show me the last 3 sites you injected?
•
If needed, would you ask for help with your injections?
Uncover Oral/IV Barriers
• What is your schedule for taking pills?
• How many pills did you miss in the past month?
• Have you had your follow-up monitoring done?
• Do you have trouble with IV access?
• Do you have storage/transportation issues?
Promoting Adherence
•
•
•
•
•
Educate
Identify and address barriers
Develop individualized strategies
Encourage realistic expectations
Advocate
–
Assist with reimbursement
–
Identify resources
–
Involve family and support system
Fostering Realistic Expectations
•
For MS patients, realistic expectations are critical
to the success of long-term disease management
•
Inform patients that disease-modifying therapies
are not curative but that they can:
–
Reduce the rate and frequency of relapses
–
Slow the progression of the disease

–
Having relapses while on treatment does not mean
therapy is ineffective; conversely, the lack of
relapses when not on treatment does not mean
disease is not progressing
Improve quality of life
Fostering Realistic Expectations
Risk of Not Treating/Delaying Treatment
•
Compared with no treatment, treatment with diseasemodifying therapy (IFN B-1a, IFN B-1b, or glatiramer
acetate)
–
Significantly delays the onset of clinically definite MS1,2,3,4
–
Significantly reduces annualized relapse rates4
–
Significantly reduces loss of brain volume1
–
Significantly reduces the number of new or enlarging lesions
and gadolinium-enhancing lesions1,4

Fostering Realistic Expectations
Risk of Not Treating/Delaying Treatment
Early vs delayed treatment
–
Patients receiving early treatment had a significantly
reduced risk of progression of disability
–
Patients receiving early treatment performed significantly
better on tests of cognitive function than those receiving
delayed treatment

therapies; include pivotal trial data, mechanism of
action, potential adverse effects
•
Refer to:
–
National Multiple Sclerosis Society
–
Multiple Sclerosis Association of America
–
Multiple Sclerosis Foundation
–
Consortium of Multiple Sclerosis Centers

Discuss dosing and consistent administration
–
Provide tips to minimize side effects, including injection
site reactions (eg, medications prior
to injection, site rotation, lifestyle, and site
of injection)
–
Address side effects
Patient/caregiver issues
–
Identify information gaps, provide education
–
Assess patient’s financial status and support wherever
possible with resources
Management of Injectable
Side Effects
•
Warm mixed medications to room or body temperature
•
Warm or ice site for 30–60 seconds before injection
•
Inject immediately after a shower
•
Use aerosolized ethyl chloride
•
Apply local anesthetics (lidocaine, benzocaine, etc)
•
For flu-like symptoms, ibuprofen and acetaminophen can be
recommended
Injection Mechanics
•
Consider autoinjectors
•
Modify needle length for body mass index
•
Avoid medication on needle tip
•
Fully penetrate the skin to avoid intradermal infiltration
•
Ensure complete vertical needle penetration into
skin surface
Management of Injection
Site Reactions
•
•
Use topical steroids for postinjection erythema
Avoid topical steroids at sites of infection or apparent
abscess or necrosis
