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

Sept 27 th 2011 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.

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

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 10 9 /l 4.discontinue drug and monitor lymphocyte count to ensure recovery 5.reduce dose to alternate days and monitor lymphocyte count to ensure recovery

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 10 9 /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.
