Diagnosis
 DMD can NOT be diagnosed using CK test only
 The diagnosis needs to be confirmed using genetic
testing
Why is it important to have a genetic diagnosis?
 It help making plans for the boy’s care
 It allows genetic counselling and carrier testing
 It prepares for possible participation in clinical trials
(mutation-specific)
Action Duchenne Conference 2015
Diagnosis of DMD
 Getting the right information on DMD
 Ask your clinician any question you have
 Contact with a support group or advocacy organization
can be of particular help (www.treat-nmd.eu/
dmdpatientorganisations)

Corticosteroids
 Currently, steroids are the only drug available that can
improve muscle strength in DMD
 Equipoises
 When should Corticosteroids be
started in DMD?
 Which corticosteroids and which
regime?
Henriette Van Ruiten: Steroids: current advances (Friday,
6th Nov, 11.30-12.30)
Action Duchenne Conference 2015
Corticosteroids
When to start?
 The plateau phase
 Age 4-5 years
 Early starter benefit more

6
yrs
 Early treatment (< 4 years) might be
associated with better long term
outcomes
 Balance with side effects

Corticosteroids
FOR DMD study
Find the Optimum Corticosteroid Regime for DMD
 Randomized, double blind, multi-centre international study
 Aim to compared the three more commonly prescribed corticosteroid
regimes in DMD
Prednisolone 0.75 mg/kg daily
Deflazacort 0.9 mg/kg daily
Prednsilone 0.75 mg/kg 10 days on and 10 days off
 Benefits and side effects
 The study will inform clinician and families about which regime is
associated with the higher benefits and better side effect profile

 225 boys
 4-7 years old, steroid naive

Corticosteroids
What to start?
 Prednisolone 0.75 mg/kg daily
 Deflazacort 0.9 mg/kg daily
 Prednisolone 0.75 mg/kg 10 days on/10 days off
 Alternate day regime has been shown to be less effective
than daily regimes
 Doses < 0.3 mg/kg/day are not effective
 Inclusion criteria for clinical trials are becoming strict on
corticosteroid regimes
Action Duchenne Conference 2015
Corticosteroids
 Discussion about corticosteroids should be done soon after the
diagnosis
 Pre-steroid assessments
 Blood tests (haematology, biochemistry, including
glucose)




IgG varicellla Zoster
Cardiac check (ECG and Echocardiogram)
Bone density scan (DEXA)
Eye check (to exclude cataracts)
Action Duchenne Conference 2015
Corticosteroids
 Follow up: 3 and 6 months after starting treatment and every 6
months thereafter
 Benefits (muscle strength and function)
 Side effects (weight, height, urine dipstick, blood pressure,
behavior, bone health)
 Urine dipstick and blood pressure: every 2-3 weeks for the first 3 months
Action Duchenne Conference 2015
Physiotherapy
 Specialised evaluation
every 4-6 months
 Contracture prevention
 Appropriate exercise
Action Duchenne Conference 2015
Range of joint mobility
 Joint contractures are caused by reduced active
movements (muscle weakness) and fibrotic changes in
muscle tissue
 Prevention of joint contractures is important and should be
started soon after the diagnosis
 Avoid development of reduced joint movement
 Better tolerated
Action Duchenne Conference 2015
Contracture prevention
 At early stages, stretching
should be limited to the ankles
but should be done regularly
 Stretching should be done a
minimum of 4–6 days per week
 At home and/or school
 Assessment in clinic
 Focus on specific joints
depending on age
Action Duchenne Conference 2015
Exercise
 Regular, exercise is recommended
 Especially in young boys
 High-resistance strength training and
eccentric exercise (e.g. Trapolining) are
inappropriate
 Swimming-pool exercises and recreationbased exercises in the community.
 Myoglobinuria can be a indicator of
overexertion
Action Duchenne Conference 2015
Bone Health
 Boys with DMD have a reduced bone density even
before staeroid treatment
 No specific interventions required at early stages
 Vitamin D supplementations
 Vitamin D3 800-1000 IU/L
 Any child < 5 years
 All boys on steroids
 In case of Vitamin D
insuffiency/deficiency
Action Duchenne Conference 2015
Referrals after diagnosis
 Respiratory physician
 Force Vital Capacity, Peak cough flow
 Pneumococcal vaccination
 Annual Flu jab
 Cardiologist
 ECG and Echo
 At diagnosis, every 2 years until the age of 10, annually
thereafter
Action Duchenne Conference 2015
Neurodevelopmental and
psychosocial issues
 Possible co-existence of
 Learning disability
 Speech and language problems
 ADD/ ADHD, Autism spectrum disorder, OCD
 Need for assessment and management
 Individualised educational plan
 Active attention to social isolation, adjustment, coping
Action Duchenne Conference 2015
Being ready for clinical trials
 Any therapeutic approach is likely to be most
successful in early stages of the condition when the
muscles are less damaged and therefore in young
children
 Receiving standards of care
 Being on the patient registry
Action Duchenne Conference 2015
DMD Registry
 Database for all patients with DMD (BMD and female
carriers)
 Genetic and Medical information
 Identification of subjects suitable for clinical trials
 Geographically locate subjects with specific characteristic
(site selection)
 Keep patients and families informed about research,
clinical trials and outcomes

 Taking step by step
 DMD is a condition that changes with time
 Intereventions needs to be adjusted based on the
