CASE 1

Case 1 - History• 37 year old man of mixed heritage with active RRMS.• Symptom Onset and Diagnosis

• 9/2017 presents to Gen Neuro for left leg weakness/numbness with more falls describes progressive worsening of falls

• 10/21/2017 presents to the ER for room spinning dizziness that is positional with blurry vision – diagnosis is made

• Seen in MS clinic 10/26/2017• EDSS - 3

Case 1 - Symptoms• Cognitive dysfunction• Fatigue• Dysphagia subjective• Left leg weakness with foot drop• Left leg numbness• Room Spinning Dizziness• Intermittent Blurry Vision

Case 1 - medications• Meclizine - Dizziness

Case 1-ImagingCervical Spine MRI SagittalStir

Case 1 -ImagingCervical Spine MRIAxial T2 Arrow shows a dorsal lateral lesion level of C6

Case 1 –ImagingCervical Spine MRIAxialT1 with contrastCentral enhancement at C2

Case 1 – Lab work up• ANA panel negative• RF negative• Lupus Anticoagulant negative• B12: 423• Initial JCV Stratify Ab: 1.38 (positive)• HIV negative• Hep B and C negative• Vitamin D: 49

Neuropsychological Consultation• Cognitive testing indicates primary difficulties in domains of

working memory, processing/psychomotor speed, and verbal learning and memory. Some difficulties in aspects of language, and executive function. Reasoning abilities are largely normal.

• Memory difficulties are likely due to encoding rather than retrieval difficulties. It is possible that slowed processing speed and deficits in working memory are hindering the encoding process.

• Significant decline in verbal learning and memory, working memory, and processing speed compared to results 3 years ago.

• History of depression, chronic pain, and migraine may confound results.

Case 1 – Questions• How do you classify the severity of the patient’s MS?• How would you utilize the severity of the patient’s MS in

treatment decisions?• Is Induction therapy appropriate for this patient?• Thoughts about treatment course taken?

CASE 2

Case 2• 33 year old AA male with active relapsing-remitting MS• Symptom onset and diagnosis:

• 2005 ED without bladder symptoms (age 21yrs)• 2006 bilateral optic neuritis• 2007 (leg weakness and foot drop)-diagnosis made

• Initiated care at DCVA 2009• 2017

• EDSS: 5.5/6.0• Evidence for disease activity clinical and on MRI• Relapses free since 2011

Case 2-Symptoms• Cognitive dysfunction• Fatigue• Dysphagia (mild)• Dysarthria- staccato speech)• Neurogenic bowel and bladder (behavioral management)• Bilateral intention tremor • Left leg weakness with foot drop• Asymmetric spastic paraparesis

• Gait: independent; wears 4lb ankle weight

Case 2-Medications• Calcium carbonate 1.25mg daily• Cholecalciferol 2000IU daily• Fish oil 1000mg twice a day• Quarterly pulse steroid infusions

Case 2-Relapse History• 2009: left foot drop- initiates Ampyra• 3/2010: poor hand dexterity resolved untreated; fatigue• 7/2010 foot drop worsens; note LLE atrophy; difficulty

sleeping (EDSS 6)• 9/2010: orange flashing in left eye; blurred vision;

resolved no tx.• 1/2011 DC Ampyra and improvement in balance and

sleep• 7/2011:retrobulbar optic neuritis with bitemporal

hemianopsia; VA: 0/30; OS: 20/200; steroid tx• 9/2011: several enhancing lesions MRI; tx. Steroids

• Pulse steroids (three months)• Rituximab: 5/2015 single dose- infusion reaction and

refuses further treatment with rituximab.• Quarterly pulse steroids 2015- to present • Wellness focus (diet- modified Paleo; dark chocolate)

JCV Ab Index Reference:<0.20 negative0.20-0.40 Indeterminate>0.40 Positive

DMT Associated Benefits and Harms• 3/2012: viral syndrome preceded papular rash on trunk

and spread to legs- stopped fingolimod and rash resolved within a month

associated with with fever (natalizumab 10 doses); dx.: leukocytoclastic vasculitis; natalizumab held but resumed when rash resolved; rash treated: prednisone, doxycycline, acyclovir

• 9/2014: herpes zoster infection following steroid infusion subsequent to natalizumab discontinuation.

Discussion• How should we best manage medication side effects?

• What are the next steps with this risk adverse, complicated by autoimmunity, young, African American male patient?

• What nondrug approaches are available and is his current wellness plan and intermittent steroids enough for life?

CASE 3

Case 3 70 year old man with 32 year history of Multiple Sclerosis.• Symptom Onset and Diagnosis

• 1987 presents to Neurologist for bilateral leg numbness• Seen by Neurology – MRI/VEP/SSEP/LP confirmed diagnosis• Minimal relapses and mostly sensory symptoms• 2004 – Sensory loss in LE progresses to weakness• 2009 – He progressed to use of wheel chair• Same time developed bladder incontinence• He notices worsening constipation• Told during this time his MRIs are unchanged• EDSS – 6.5

Case 3 – Clinical Course• 2009 – wheelchair bound/ bladder

incontinence/constipation• 2011 – patient’s wife notices low volume to voice and

weak cough• 2013 – more trouble with pain and hand weakness• 2014 – mild dysarthria• 2015 – worsening cognitive function and sleep

disturbances• 2017 – PFT shows neuromuscular weakness

Case 3 - ImageSagittal Flair – several ovoid lesions

Case 3 -imagesMRI axial T2 – shows atrophy of brainstem and cerebellum

Case 3 -ImagesCervical Sagittal T2 Stir – Shows several lesions with frank spinal cord atrophy

Case 3 -ImagesAxial T2 Cervical spine MRI – shows cord atrophy

Case 3 – DMT History• 2000 – Trialed Copaxone • 2004 – Trialed IFN• 2015 – Discussed oral therapy vs High Efficacy therapy• Patient decided risk does not outweigh benefit of therapy

Case 3 - Symptoms• Paraplegia• Chronic neuropathic pain• Speech study – showed mild dysphagia, weak cough, and

hypophonia, mild dysarthria• PFT – Shows neuromuscular weakness• Bladder incontinence• Constipation• Cognitive fatigue• Central Sleep Apnea• Fine motor weakness of bilateral hands

Case 3-Questions for Discussion?• Patient opted to focus on quality of life, what is the impact

his secondary symptoms have on his functionality?• What methodology and medications might you use to

improve a patient’s quality of life?• What non medication and holistic approaches would you

recommend?• What should the providers be concerned about when

prescribing medications for this patient?• Are there situations where medication could worsen

quality of life for this patient?

CASE 4

Case 453 year old W Hispanic female with history of secondary progressive MS. Onset symptoms were transient numbness and tingling in both legs in 2003, diagnosis 2011 with onset of paraparesis and ataxia. MRI of brain and spinal cord c/w MS and CSF revealed +OCB. Increased gait ataxia forced patient to use cane permanently in 2012. Weight gain increased with development of comorbid DM and HTN.

• PMH: Hyperlipidemia, Obesity, Diabetes mellitus II, HTN• MEDS: Interferon beta 1a, metformin, oxybutynin, lisinopril,

tamsulosin, vitamin D• SH: Married, living with spouse and one teenage daughter,

working as a DoD contractor, no smoking or alcohol

Case 4

Case 4 (continued)• PE:• MSt: alert, orientated to time/place, some deficits in

complex attn tasks and delayed recall• CN: normal• Reflexes: L sided hyperreflexia with + Babinski• Motor: spastic paraparesis (R>LLE)• Sensory: hypoesthesia RUE/R trunk/RLE, mild stocking

loss to pain/temperature bilaterally• CSG: R sided ataxia with FNF and HKS, uses cane to

walk short distance (50-100’) and wheelchair for longer distances

Case 3 (cont.)• 2016-2017: Worsening symptoms fatigue, leg weakness,

bladder urgency/incontinence, and moderate cognitive changes. SDMT: Raw Score:48, Normed Score:82, Percentile Rank:11.7

• Attempts at reasonable accomodations, EEO complaint, fired from DoD contracting job in later 2017

• Poor glucose control (HgbA1c: 11)• Bladder urgency, frequency and incontinence• Depressed mood

Discussion• How do co-morbid conditions influence disability? How

might these issues be managed?• Cognitive dysfunction and mood changes appear to be a

factor in the patient’s job loss. What could be done to intervene?

• What are ways to assess and manage the patient’s neurogenic bladder symptoms

• How would a multidisciplinary care team assist in the management of this patient?

Conclusions• Whole health principle important in approaching patients

with MS• Understanding the risk-benefit of MS DMTs critical for

guiding treatment decisions• Symptomatic care requires an understanding of MS and

the impact of comorbid conditions• MSCoE hub and spoke system of care along with SCI/D

centers offers important spectrum of expertise throughout the life cycle of patients with MS
