Overview
• The diagnostic criteria of multiple sclerosis(
MS)
• Classification of idiopathic inflammatory
demyelinating disorders
• Clinical course of MS
• Current and emerging MS therapies
Idiopathic CNS Demyelinating
Diseases
• Typical CNS demyelinating Diseases:
– Radiologically isolated syndrome (RIS)
– Clinically isolated syndrome (CIS)
– Relapsing –remitting multiple sclerosis (RRMS)
– Secondary progressive MS (SPMS)
– Primary progressive MS (PPMS)
Atypical CNS Demyelinating Diseases
• Acute disseminated encephalomyelitis
(ADEM)
• Acute hemorrhagic leukoencephalitis (AHLE)
• Tumefactive MS
• Balo’s concentric sclerosis
• Marburg
Radiologically Isolated Syndrome
(RIS)
–

–
No typical symptoms of CNS demyelination
No formally accepted diagnostic criteria
MRI : Typical MS lesions
CSF abnormalities
Clinical MS Attack:
35% over 5 years
MRI progression:
• 59-83% in 2 years
– DMT is initiated only in case
of clinical/MRI progression
Okuda DT et al, Neurology2011:76()8, 686-692
Diagnostic Criteria for MS
• An effort to make the diagnostic process more
objective
• Formal criteria were devised to codify the typical MS
features into indisputable diagnostic criteria
• The primary driving force is identification of patients
for research trials. ”a consensus on which patient has
MS”
• Criteria are designed to be specific
• There are patients with MS who do not meet those
criteria
• “A patient has MS when an an experienced neurologist
says he or she has MS”
Schumacher Criteria- 1965
• Onset of symptoms between 10 and 50 years
• Objective abnormalities on neurologic
examination
• The signs and symptoms indicate CNS white
matter damage
• The lesions are disseminated in space ( 2 or more
separate lesions)
• The lesions are disseminated in time (2 attacks at
least 1 month apart)
• No better explanation
The Mc Donald Criteria
• ‘the world consists of three types of person: those who
have multiple sclerosis; those who do not; and those
who might’. Polman CH et al,Ann Neurology, 2001

CASE
• On 18/3/08 patient complained of ocular pain on
moving the left eye with blurred vision.
• 2 days later she developed left frontal headache.
• Seen by the ophthalmologist who diagnosed her as
optic neuritis and advised to be on neurobion.
• She had several attacks of Rt. Upper limb heaviness
in the last 2 years, each was lasting for a week.
• Her cousin has MS .
CASE : Examination
• Her vision was 20/200 in the left eye and 20/40 in the
right eye. There was a central scotoma, and red and
blue colors were less intense in the left eye.
• RAPD on the left
• Left fundus: disc is congested and swollen.
• Central Scotoma
• Treated with pulse IV methylprednisolone for 3 days
and improved followed by short prednisolone taper
Case 1: Fundoscopy
Case : MRI Brain
Case 2: MRI Spine
Case : CSF Oligoclonal bands
Clinically Isolated Syndrome (CIS)
• Single characteristic clinical attack of CNS
demyelination:
– Optic neuritis
– Acute partial myelitis
– Brain stem syndrome
– Cortical
•
Clinically Isolated Syndrome (CIS)
• MRI:
– Low risk: 1 or no other asymptomatic brain lesion
– High risk: 2 or > asymptomatic lesions
• Treatment approved for high risk patients
– IFN-B, GA reduces second attack: ARR 15%

CIS: When To Initiate Therapy?
• Patients with normal MRI or with fewer than 2
– Low risk of developing early clinical attacks
– Clinical and MRI monitoring
– Without immediately commencing immunotherapy
(DMT)
• Those with abnormal MRI with2or> lesions
consistent with MS or with evidence of
intrathecal synthesis of antibodies should be
considered for DMT,
• Patients with atypical clinical or MRI presentation
require further diagnostic evaluation.
Relapsing-Remitting MS
• Subacute repeated onset of CNS dysfunction with
resolution ( sometimes incomplete , over days to
weeks)
• Revised McDonald criteria
• MRI: Periventricular, brainstem, juxtacortical
prominent T2, often Gad enhancing lesions, T1
hypointense (black holes)
• Treatment: Interferon-B, Glatiramer acetate,
natalizumab, mitoxantrone

Features Inconsistent With MS
• Steady progression
• Onset before age 10 or after age 50
• Cortical deficits such as aphasia, apraxia, alexia,
neglect
• Rigidity, sustained dystonia
• Convulsions
• Early dementia
• Deficit developing within minutes
Secondary Progressive MS
• Majority of RRMS many years following onset
• Progressive impairment (spastic gait
disturbance) between or in absence of attacks
• No clear effect of DMT without ongoing
attacks or inflammation
• Role of DMTs in SPMS patients:
– with ongoing relapses
– Substantial ongoing accrual on new MRI
inflammatory lesions
Primary Progressive MS
• Presents with progressive myelopathic gait,
cerebellar ataxia or cognitive impairment without
clear history of any clinical attacks
• Clinical progression must be for at least 1 year
and accompanied by a combinstion of
brain&spinal abnormalities and/or CSF
anormalities consistent with MS
• Lack of clinical attacks/ relative paucity of MRI
lesions
• No approved DMTs
Multiple Sclerosis (MS)
• Multiple Sclerosis is the commonest disabling
neurological condition to afflict young adults
• MS is an autoimmune disease triggered by
environmental agents acting in a genetically
susceptible people
• Auto-aggresive autoimmune attack on the
myelin sheath and other components of CNS
• Current&emerging DMTs are based in the above
paradigm
• Is MS a primary neurodegenerative disease

MS Therapy: Deciding on which
Medication
• Determine Therapeutic Goals
– To reduce clinical relapse
– To reduce accumulation of new MRI lesions
–  new T2 lesions
– Gadolinium-enhancing lesions
– black holes
– Brain and spinal cord atrophy
• Reduce short-term relapse related disability
How To Determine of The Goals are
Met?
• Compare with baseline relapse rate
– Recall bias
– Regression to the mean
• Assessment of improvement or stability in
neurological impairment
– Assess functional ambulatory limitation
• May indicate progression
• MRI ongoing/new inflammatory activity
– Serial MRI to assess radiologic stability, worsening or
improvement- q12-24 month except
How To Determine of The Goals are
Met?
• If goals of DMT or symptomatic treatment are
being met no change in DMT unless
problems with medication tolerability
• A detailed evaluation of common and
idiopathic side effects will be required
– Switching of medication based on adherence and
tolerability ma be needed
What if Goals are not being Met
• If pre-therapy relapse rate is not improved
– A therapeutic switch may be indicated
• Relapse rate is incomplete indicator of ongoing
inflammatory disease activity
– Cranial and spinal MRI
• May show therapy resistant inflammatory disease
• Guide switch to a more potent anti-inflammatory
medication
• Clinical attack or definitive worsening disability is may
lacking
Case 2
• Mr. A.M.J is a 33 years old Kuwaiti male, diagnosed to
have MS in 2008.
• In Jan 2008, he developed diplopia, followed by
paresthesia in feet, ascending to abdomen, chest and
forearms.
• These symptoms persisted
• By June 2008, he was ataxic and on a wheel chair,
when he sought medical advice
• MRI was consistent with MS
• Marked imrovement was noted in sensory symptoms
after pulse steroids.
Case 2
• His symptoms showed a rapid progression, by
Sept 2008, he had optic neuritis, sphincteric
disturbance, and positive Lhermitte’s sign.
• In Oct 2008, he started to take Rebif.
• His disease remained stable, with no new
relapses and no new lesions on MRI till 2011.
• In April 2011, he went for CCSVI treatment
and discontinued Rebif without our
knowledge or advice.
CASE 1
•
•
•
•
•
•
•
•
Lhermitte’s sign was positive
Cranial nerves were normal
No motor weakness
Mild sensory deficit for light touch and vibration
on left side
Plantars were flexor bilaterally
Romberg’s sign was mildly positive
Moderate left sided dysmetria, with tandem
ataxia
EDSS :2; AI :1.
Case 1: MRI Cervical spineTWI
Case 2
•
•
•
•
•
In August 2011 he reported dizziness, ataxia and diplopia
He was treated with pulse steroids with marked recovery.
He was clinically stable, and was advised to restart Rebif.
In Jan 2012, EDSS:1, AI:0.
MRI in June 2012 showed new cerebellar lesions, with no
enhancement.
• In Oct 2012, he came in with a mild relapse and was
treated with pulse steroids.
• An MRI in Dec 2012 showed worsening lesion load, and he
was advised to start Tysabri after JCV serology.
• He started Tysabri in Dec 2012, and till 5 months post
Tysabri , there were no active lesions.
Case 2
• In Sept 2013, patient came with another
severe relapse , with homonymous
hemianopia, sphincteric problems, gait ataxia,
and sensory disturbance.
• Treated with pulse steroids with partial
improvement in urinary symptoms and ataxia,
but not in visual symptoms.
Case 2: MRI Brain 2
Case 2: MRI Cervical spine 2
Case 2
• MRI showed marked worsening, with
tumefactive enhancing lesions
• A CSF study was done, which was normal,
negative for JCV.
• Considering this as a failure of Tysabri, it is
planned to treat him with Rituximab
Is Clinical Worsening due to Attack
related Disease or Progression?
• If it is due to non-inflammatory MS
progressive disease
– Neurodegenerative MS
– ?subclinical ( and sub-radiologic) inflammation
unresponsive to current DMTs
– Switching to alternative MS therapy is futile
• Escalating therapy If clinical impairment is
strongly associated with ongoing relapses or
marked new inflammatory MRI activity

Drawback of injectable Medication
• Interferon-β
– “Flue-like illness” often transient
– Liver enzyme monitoring
– Rarely depression
• Glatiramer acetate
– Flushing, eosinophilia, rare allergic reaction,
injection-site reactions (skin liopatrophy)
– Conbination therapy+interferon-β1a IM/weekly
and glatiramer acetate does not appear to be
significantly more efficacious than monotherapy

 Integrated analysis
• Compared with PBO, BG-12 240 mg BID and TID
significantly reduced ARR, risk of relapse, adjusted ARR
requiring steroids, disability progression, and MRI
outcomes.
• Demonstrated consistent benefits on clinical efficacy
across prespecified subgroups of RRMS pts with varied
baseline demographics and disease characteristics
• Overall incidence of AEs, SAEs, and discontinuations
due to AES similar across tx groups; flushing and GI

Fingolimod
• Treatment with fingolimod 0.5 mg:
– Significant benefits on relapse-related outcomes within first 3 months
and on volume loss over 6 months compared with PBO in FREEDOMS
and FREEDOMS II studies; concordant results from 2 large phase 3
trials, along with phase 2 data, allow better definition of expectations
regarding time lag between initiation and effects of fingolimod
treatment
• Fingolimod treatment initiation effects in pooled population from
FREEDOMS, FREEDOMS II (vs PBO), and TRANSFORMS (vs IM IFN à1a) a transient, mostly asymptomatic decrease in heart rate;
symptomatic bradycardia and Mobitz I and 2:1 AVBs were dosedependent; AVB first occurrences most common <6 h post-dose5
• Analysis of TRANSFORMS trial demonstrated advantage of
switching to fingolimod over remaining on IFN à-1a IM with regard
to time to relapse in RRMS6
