Overview

• Background

• Symptoms and signs of MS

• Diagnosis

• Update on treatments

• Moving On and Beyond

Background

• MS is the most common cause of neurological disability in young adults in the UK

• Working age population

• Prevalence 80-100,000 people with MS in UK

• Leeds – population 750,000 - 858 people with MS and 45 new cases per year

What is MS?

• MS is a disease of the central nervous system (CNS)

• An inflammatory reaction in the CNS causes loss of myelin and slowing of nerve conduction

• Areas of demyelination

• Loss of axons

Sites that are vulnerable to demyelination

• Optic nerves

• Brainstem

• Cervical cord

• Periventricular regions

Optic neuritis

• Blurred vision or loss of vision in one eye – often central

• Pain on moving the eye

• Impaired colour vision

• Reduced visual acuity• Normal or swollen

disc• Central scotoma• Pupil relatively dilated • ‘Afferent pupillary

defect’

Brainstem demyelination

• Double vision• Loss of balance• Clumsiness

• Eye movement disorder

• Nystagmus• Intention tremor• Ataxia

Spinal cord

• Limping or dragging one leg

• Numbness, tingling, tight band-like sensation

• L’Hermittes• Bowel and bladder

symptoms

• Increased tone, pyramidal weakness, brisk reflexes, extensor plantars

• Loss of vibration sense

• Sensory level

‘Invisible symptoms’

• Cognitive impairment – even at early stages of disease

• Fatigue – first and worst

• Pain

• Unpleasant or disabling sensory symptoms

MS disease course

Favourable prognostic indicators

• Early age at onset

• Female sex

• Relapsing remitting course

• Optic neuritis or sensory symptoms at onset

• Few attacks during the first 5 years

Making the diagnosis

• Clinical diagnosis• History: neurological

events separated in time• Examination: Signs of

damage to different areas of the CNS i.e. neurological signs separated in space

• Investigations: supportive not diagnostic

Aims of treatment

• Reverse existing impairments and disability

• Prevent long-term disability

• Reduce relapse rate

April 1993

Pivotal trial of Betaseron

Disease modifying treatments

• Interferon beta 1-b• Interferon beta 1-a• Copaxone• Natalizumab• Fingolimod

Interferon beta

• Reduces the number of relapses by a third

• Effective early in the disease course

• Eligibility -2 clinically significant relapses in previous 2 years

• No evidence of long-term effect on disability

Outcomes for the West Yorkshire treated population

• Does treatment with a disease-modifying drug influence the quality of life of people with MS?

• Do certain groups of patient respond better than others?

Natalizumab

• Humanised monoclonal antibody

• Inhibits trafficking of leucocytes across blood brain barrier

• Recommended for treatment of Rapidly Evolving Severe MS

• Risk of PML

New oral treatments

• Fingolimod - licensed by EMA 2011 -(Sphingosine 1-phosphate (S1P) receptor modulator which reduces peripheral blood lymphocytes due to the inhibition of S1P(1)-dependent lymphocyte egress from secondary lymphoid organs and thymus)

• Reduces relapse rate by 60%

Summary of current treatment

• Course of relapsing-remitting MS can be modified

• Uncertain/if any impact on later disease progression

• Newer drugs have different side effect profiles eg PML, cardiotoxicity

• New oral drug licensed and awaiting NICE approval

Severe Progressive MS

• Cognitive problems

• Speech and swallowing difficulty, PEG feeding

• Tremor affecting upper limb function

• Severe spasticity

• Urinary and faecal incontinence, catheterisation

Moving On and Beyond

• New programme for people with MS, MND and Heart failure

• ‘Empowering people with life limiting conditions to take control and live a new life to the full’

Objectives• Improve access to the Hospice for non cancer

patients • Develop opportunity for peer

support/empowerment for service developers & course attendees

• Collaborative working to address survivorship and Specialist Palliative Care for non cancer patients.

• Focus on survivorship, coping & advance care planning.
