Does the biology of MS change with time?

TOP: earlier natalizumab treatment favours annualised relapse rate outcomes

P values from a negative binomial regression model adjusted for gender, baseline EDSS score (<3.0 vs ≥3.0l), relapse status in the prior year (≤1 vs >1), prior DMT use (<3 vs ≥3), disease duration (<8 vs ≥8 years), and treatment duration (≥3 vs <3 years), except for the factor of interest.

Health is a state of complete physical, mental and social well-being and not merely the absence of disease or

Positive side effects

Rietberg MB et al. (2004). Exercise therapy for multiple sclerosis. Cochrane Database of Systematic Reviews.

Strong evidence in favour of exercise therapy vs no exercise therapy in terms of:• Muscle power function• Exercise tolerance• Mobility-related activities

Exercise therapy is well tolerated

No evidence for a positive impact of exercise therapy on symptoms of fatigue

Cognitive dysfunction • Cognitive dysfunction is observed in up to 65% of PwMS and impacts

employability, activities of daily living, social and family functions and overall quality of life (Feinstein et al., Mult Scler Relat Dis 2013, 2: 4-12)

Systematic review: Sandroff et al., Neuropsychol Rev: Epub 22 July 2016

• Collectively, there is insufficient well-designed research to definitively conclude that exercise, physical activity, and physical fitness are effective for improving cognition in MS.

• Promising evidence from non-randomised trials may be useful for informing the development of better intervention research.

• Very common amongst PwMS: Annual prevalence rate of 20% and lifetime prevalence rate of 50% (Sadnovick et al., Neurology 1996, 46:628-632)

Cross-sectional study of 2459 PwMS: Taylor et al. BMC Psychiatry 2014, 14:327:

• Poor diet, low levels of exercise, obesity, smoking, marked social isolation and taking interferon were associated with greater depression risk in PwMS, whereas use of omega-3 FA and vitamin D supplements, frequent fish consumption, moderate alcohol consumption and meditation reduced depression risk.

Challenges for exercise studies in MS• Fatigue• Relapse• Heterogeneous range of symptoms, disabilities• Heat sensitivity• Flexible approach needed• Control of exercise stimulus

“Exercise training programs have traditionally been discouraged in the MS population because of the belief that they might exacerbate fatigue and other MS symptoms. To the contrary, recent studies have demonstrated positive effects of physical therapy and increased physical activity in reducing pain and improving mobility in MS patients.”

Filipi et al. (2010); Int J MS Care 12, 6–12.

Notes Of the 5 largest controlled trials (N=39-112), 3 reported improvements in fatigue.

Key points

• Heterogeneous findings between studies• Studies have not targeted patients who are

experiencing significant levels of fatigue• Only a few studies have evaluated fatigue as

the primary outcome measure• Only 12/21 studies were RCTs• Choice of fatigue scale may have some

bearing on the results

Comorbidities in Multiple Sclerosis

Ruth Ann Marrie, MD, PhDProfessor of Medicine & Community

Health SciencesUniversity of Manitoba

Winnipeg, Canada

Psychiatric Comorbidity is Common• Depression

– Up to 50% lifetime prev. (3X higher than gen pop’n)

– 12-month prev. 14% (vs. 5.9-7.3% in gen pop’n)

• Anxiety– up to 35% lifetime prevalence

– Generalized anxiety disorder, social phobias

• Other disorders → less studied– Bipolar disorder: 5%

– Psychosis: 0.9-1%

• Under-diagnosed & undertreatedMarrie RA et al. MSJ 2015;21:305-317

Most Common Physical Comorbidities in MS

• Hypertension* 18.6% (13.9-23.2%)• Hyperlipidemia 10.9% (5.6-16.1%)• Chronic lung disease 10.0% (0-20.9%)• Irritable bowel syndrome 12.2%

• Thyroid disease 6.4% (0.19-12.7%)• Psoriasis 7.7%

*leading causes of disability in gen. pop’n are hypertension, arthritis, back/ spine problems, lung disease, and heart disease

Marrie RA et al. MSJ 2015;21:263-281

Comorbidity is common at diagnosis• 4 Canadian provinces: 23,382 incident MS cases & 116,638

matched controls

2 1.80 (1.35-2.40)3 2.11 (1.58-2.83)

≥4 3.65 (2.78-4.78)

Implications I• Comorbidity common in MS & affects outcomes• Consider when developing plans of care

• MS Team needs to be involved in: – diagnosis & management of comorbidity → depression,

anxiety, vascular in particular– educate patients & families

• Health promotion (next talk)– Address health behaviors: smoking, diet, weight,

physical activity– Preventive care

Conclusion

• Comorbidity is common in MS

• Associated with broad range of adverse

outcomes: disability, QOL, hospitalizations,

mortality

• Affects treatment choices & responses

• Requires team approach, and possibly changes

in models of care to achieve optimal outcomes

Conclusions• MS is a bad disease

• Mortality, disability, unemployment, divorce, cognitive impairment, etc.

• On average early effective therapy is the only realistic option of preventing end-organ damage • NEDA and T2T are current treatment target (zero tolerance)• Beyond NEDA we need to target end-organ damage (brain atrophy,

CSF NF levels, etc.)• Brain Health initiative
