epidemiology and nomenclature

risk factors for MS

• smoking (HR 1.48)– duration and intensity– also risk factor for progression

• vitamin D status– >100nmol/L HR 0.5 vs <75nmol/L

• EBV– 100% MS seropositivity vs 95% controls– IM HR 2.17

treating MS

• treatment of acute relapse

• disease modification– disease modifying treatments (DMTs)

• management of symptoms and disability

• management of symptoms and disability

case

• a 34-year-old woman with MS• 2d history of worsening intense pain in a band, right side,

roughly T7 distribution. • generally fatigued and her right leg feels heavier • worsening hesitancy• feels similar to a previous relapse successfully treated

with oral steroids in primary care• on oral fingolimod for 6 months• fully ambulant with no new signs on examination

would you?

1. prescribe oral steroids

2. prescribe oral steroids only after checking for a UTI

3. acknowledge episode as relapse but withhold treatment awaiting natural history

4. ask her to contact her MS team if symptoms don’t settle

5. refer as emergency to MS team

management of acute relapse

• increasingly rare: usually in consultation with local MS team

• methylprednisolone– oral 500mg x 5d (PPI cover if symptomatic)– IV 1000mg x 3d

• always specialist centre if on natalizumab, fingolimod or alemtuzumab

• treatment of acute relapse

• disease modification– disease modifying treatments (DMTs)

• management of symptoms and disability

where are we leaving?

• NI population study 19961, n=281

– fully independent for all ADLs

29%– unable to manage flight of stairs

23% – in full time employment

25%– institutionalised

5%– unable to use public transport or drive

risk management with natalizumab

PML risk estimates by index threshold in anti-JCV Ab+ patients with no prior IS use

PML risk estimates for anti-JCV antibody index thresholds were calculated based on the current PML risk stratification algorithm (from September 2012) and predicted probabilities shown in the previous slide (8) for the population at or below that particular index (0.9−1.5) and for the population above an index of 1.5. For index thresholds below 0.9, patient numbers were insufficient to allow for calculation of risk estimates.

presentation of PML

• asymptomatic (MR screening)• cognitive/behavioural• ataxia• hemiplegia

alemtuzumab

• NICE approval for “relapsing MS”

• dosing schedule: – year 1: 5d 12mg infusion – year 2: 3d 12mg infusion– subsequent years: 3d infusions if indicated

risk management strategy

• predose: VZV, cervical screening, HIV, HBV, HCV, TB

• aciclovir for first month• monthly for 4 years after last infusion

– CBC (platelets)– U&E and urine for microscopy– TFTs 3 monthly

• annual MRI (for efficacy)

long term study

• 87 patients 1999-2007• median 7 year follow up (33-144 months)• 48% (41 patients) had secondary autoimmunity

– 3 ITP– 1 neutropenia– 1 haemolytic anaemia– 1 Goodpasture’s (transplant required)– 35 thyroid (22 Graves, 1 transient thyroiditis, 12 1o

hypothyroidism)• relapses triggered reinfusion 45%

– (38% 3; 4% 4; 1% 5)

• 60% stabilisation of improvement in disabilityTuohy et al 2014 JNNP 10.1136/jnnp-2014-307721

DMT cases in primary care

case

• 34-year-old woman • presented for advice following a positive home

pregnancy test, 7 weeks after her last menstrual period

• teriflunomide 14mg daily for 9 months for relapsing remitting multiple sclerosis

• relapse free for 5 years. • relying on condoms for contraception• conception was unplanned but wishes to

continue with the pregnancy

options (nurses all on study day)

1. teriflunomide should be cleared by cholestyramine

2. teriflunomide should be cleared rapidly by plasmaphoresis

3. teriflunomide should be continued throughout the pregnancy

4. teriflunomide should be discontinued and allowed to clear gradually

5. termination is advisable due to an unacceptable risk of teratogenicity

case

• 42-year-old man • 18 month review on fingolimod 0.5mg• no attacks on the drug which was well tolerated

• felt well, had no history of infection and remained at work

• routine bloods

would you (neurology team on team bonding away day)?

1. admit immediately to unit equipped to manage severely immunocompromised patients

2. check JC antibody status to stratify risk of progressive multifocal leucoencephalopathy

3. continue at current dose while lymphocytes remain >0.2 x 109/l

4. discontinue drug and monitor lymphocyte count to ensure recovery

5. reduce dose to alternate days and monitor lymphocyte count to ensure recovery

case

• 42-year-old man • 18 month review on dimethyl fumarate 240mg

bd • no attacks on the drug which was well tolerated

 • felt well, had no history of infection and

remained at work• routine bloods

would you (neurology team all abroad at conference)?

1. admit immediately to unit equipped to manage severely immunocompromised patients

2. check JC antibody status to stratify risk of progressive multifocal leucoencephalopathy

3. continue at current dose while lymphocytes remain >0.2 x 109/l

4. discontinue drug and monitor lymphocyte count to ensure recovery

5. reduce dose to 120mg bd and monitor lymphocyte count to ensure recovery

case

• 36-year-old man with multiple sclerosis • 15 months after his completing his second year

of alemtuzumab (3 x 12mg infusions)• clinically well with no relapses or progression.•  no evidence of infection, rash or bruising.

plan?

1. monitor

2. admit as emergency

3. refer back to centre

case

• 37-year-old woman MS • presents late afternoon following an episode of

transient loss of consciousness lasting about one minute.

• returned from two weeks abroad that morning and recommenced her medication which she had omitted while on holiday.

• HR 38 beats • BP90/64

systematic enquiry of impairment/symptoms

continence in MS

1. assessment• urinary tract symptoms• bowel symptoms• sexual function• comorbidities• use of prescription and other medication

and therapies

2. if the dipstick test result and person's symptoms suggest an infection, • arrange a urine bacterial culture and

antibiotic sensitivity test before starting antibiotic treatment

• treatment need not be delayed but may be adapted when results are available

continence in MS

3. be aware that bacterial colonisation will be present in people using a catheter and so urine dipstick testing and bacterial culture may be unreliable for diagnosing active infection

4. red flags for referral• haematuria• recurrent UTI (≥3 in 6m)• loin pain• recurrent catheter blockages (<6 wk of

change)• hydronephrosis or kidney stones on

imaging (rare in MS)• biochemical evidence of renal

deterioration.

continence in MS

4. if catheters, appliances or pads:• training• access to suitable products• review of products, at least every 2 years

5. offer botulinum toxin to improve bladder storage if OAB and anti-muscarinics failed or not tolerated

6. do not routinely offer antibiotic prophylaxis but consider if recent history of frequent or severe UTI

intractable constipation: what’s new

• prucalopride (women only, specialist centre)

• Peristeen (continence service)
