General Information

What is Duchenne Muscular Dystrophy? Duchenne Muscular Dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. It is caused by mutations in the dystrophin gene, which provides instructions for making a protein that helps keep muscle cells intact.

Who does DMD affect? DMD primarily affects males, with an incidence of approximately 1 in 3,500 to 5,000 male births worldwide. It is much rarer in females, who can be carriers of the condition but typically experience milder symptoms or none at all.

At what age are symptoms first noticed? Symptoms usually appear between ages 2 and 5. Early signs include delayed motor milestones (like walking), difficulty running or jumping, frequent falls, and a waddling gait.

Causes and Genetics

What causes DMD? DMD is caused by mutations in the dystrophin gene located on the X chromosome. This gene provides instructions for making the protein dystrophin, which is essential for maintaining muscle fiber integrity.

How is DMD inherited? DMD follows an X-linked recessive inheritance pattern. Since males have only one X chromosome, they will develop the condition if they inherit the mutated gene. Females have two X chromosomes, so typically they must inherit two copies of the mutated gene to develop the full condition.

What is the chance of passing DMD to children? If a mother is a carrier:

Each son has a 50% chance of inheriting DMD
Each daughter has a 50% chance of being a carrier

If a father has DMD:

All daughters will be carriers
No sons will inherit the condition (they inherit the Y chromosome from their father)

Can DMD occur without a family history? Yes, approximately 30-35% of DMD cases result from spontaneous mutations with no family history of the condition.

Symptoms and Progression

What are the early signs of DMD?

Delayed walking
Difficulty running, jumping, or climbing stairs
Frequent falls
Waddling gait
Muscle weakness, particularly in the legs and pelvis
Pseudohypertrophy (enlarged calf muscles due to fat and connective tissue replacement)
Gowers’ sign (using hands to “climb up” the legs when rising from the floor)

How does DMD progress? DMD progresses in fairly predictable stages:

Early ambulatory (walking) phase (typically ages 3-7)
Late ambulatory phase (typically ages 7-12)
Early non-ambulatory phase (loss of walking ability, typically by age 12)
Late non-ambulatory phase (increasing weakness in upper limbs and respiratory muscles)

What muscles are affected by DMD? DMD affects all voluntary muscles, eventually impacting:

Skeletal muscles (legs, arms, trunk)
Respiratory muscles
Heart muscle
Smooth muscles (such as those in the digestive system)

Does DMD affect intelligence? DMD can be associated with non-progressive cognitive impairment in some individuals. About one-third of boys with DMD have some degree of learning disability or neurodevelopmental disorders. However, many have normal intelligence, and cognitive effects vary widely.

Diagnosis

How is DMD diagnosed?

Clinical evaluation of symptoms and family history
Blood tests for elevated creatine kinase (CK) levels
Genetic testing to identify mutations in the dystrophin gene
Muscle biopsy (less common now with advanced genetic testing)
Electromyography (EMG) testing

When should a child be tested for DMD? Testing should be considered if a child shows developmental delays, particularly in gross motor skills, unexplained high CK levels, or if there is a family history of neuromuscular disorders.

What is newborn screening for DMD? Some regions offer newborn screening for DMD by testing CK levels or through genetic screening. This is not yet universal but allows for earlier diagnosis and intervention.

Treatment and Management

Is there a cure for DMD? Currently, there is no cure for DMD. However, treatments can help manage symptoms, slow progression, and improve quality of life.

What treatments are available for DMD?

Corticosteroids (prednisone, deflazacort) to slow muscle deterioration
Gene-targeted therapies for specific mutations (e.g., eteplirsen, golodirsen)
Physical therapy to maintain muscle function and prevent contractures
Occupational therapy for adaptive strategies
Respiratory support (ventilation assistance)
Cardiac medications to manage heart complications
Orthopedic interventions (braces, surgery for scoliosis)

What are the emerging therapies for DMD?

Gene therapy to deliver functional dystrophin genes
Exon-skipping therapies that allow cells to “skip” faulty gene sections
CRISPR gene editing approaches
Utrophin upregulation (a protein similar to dystrophin)
Anti-inflammatory and anti-fibrotic treatments
Stem cell therapies

How important are steroids in DMD treatment? Corticosteroids are a cornerstone of DMD treatment, shown to prolong walking ability by 2-5 years and reduce the risk of scoliosis and cardiorespiratory complications. However, they have side effects that need careful monitoring.

Life Expectancy and Long-Term Outlook

What is the life expectancy for someone with DMD? Life expectancy has improved significantly with advances in care. Many individuals with DMD now live into their 30s and beyond, particularly with optimal cardiac and respiratory management.

What are the most common causes of mortality in DMD? Cardiac and respiratory complications are the leading causes of mortality. Proactive management of these systems has been key to improved survival.

Can adults with DMD live independently? Many adults with DMD can live semi-independently with appropriate support systems in place, including personal care assistants, accessible housing, and assistive technology.

What psychological support is recommended? Regular assessment for depression, anxiety, and adjustment difficulties is recommended. Access to counseling, support groups, and sometimes medication can be beneficial for both individuals with DMD and their families.

Genetic Testing and Family Planning

What specific types of genetic tests are used to diagnose DMD? There are several genetic testing methods used for DMD diagnosis:

Multiplex Ligation-dependent Probe Amplification (MLPA): This technique detects large deletions and duplications, which account for approximately 70-80% of DMD mutations. It’s often used as a first-line genetic test due to its ability to detect the most common mutation types.
Next-Generation Sequencing (NGS): This can identify point mutations, small deletions, and insertions that MLPA might miss. NGS panels typically include the dystrophin gene along with other genes associated with similar presentations.
Whole Exome Sequencing (WES): This examines all protein-coding regions of the genome and may be used when targeted testing is negative but clinical suspicion remains high.
Single Nucleotide Polymorphism (SNP) arrays: These can detect large chromosomal rearrangements and help identify carrier status in females.
Sanger Sequencing: This might be used to confirm mutations identified by other methods or for targeted testing of specific regions when a family-specific mutation is known.

What are the options for family planning for carriers of DMD mutations? Carriers have several reproductive options to prevent transmission of DMD:

Preimplantation Genetic Diagnosis (PGD): This involves in vitro fertilization (IVF) with genetic testing of embryos before implantation, allowing selection of embryos without the DMD mutation.
Prenatal Diagnosis: Chorionic villus sampling (at 10-13 weeks) or amniocentesis (at 15-20 weeks) can determine if a fetus carries the DMD mutation.
Non-invasive Prenatal Testing (NIPT): In some cases, cell-free fetal DNA in maternal blood can be analyzed for the DMD mutation, though this is still evolving for single-gene disorders like DMD.
Sperm Donation: Using donor sperm from an unaffected male eliminates the risk of DMD transmission.
Adoption: Some families choose adoption as an alternative to biological children.
Egg Donation: For women with DMD (rare but possible), using donor eggs eliminates the risk of passing on the condition.

Each option has medical, ethical, and practical considerations that should be discussed with genetic counselors and reproductive specialists.

Carrier Symptoms and Testing

Do female carriers of DMD experience any symptoms? Yes, female carriers can experience symptoms, though they’re typically milder than in affected males:

Exercise Intolerance: Reduced stamina and exercise capacity are commonly reported by symptomatic carriers.
Muscle Symptoms: About 20-25% of carriers experience some degree of muscle weakness or fatigue. This can range from mild calf hypertrophy and muscle cramps to more significant weakness resembling Becker muscular dystrophy (a milder form of dystrophinopathy).
Cardiac Involvement: Up to 40% of carriers develop cardiomyopathy, particularly dilated cardiomyopathy, by age 40. This can occur even in carriers without skeletal muscle symptoms.
Cognitive and Behavioral Issues: Some carriers have subtle cognitive or learning difficulties, though these are generally milder than in affected males.
Elevated Creatine Kinase (CK): Many carriers have elevated CK levels, even without other symptoms, which can be an indicator of carrier status.

The variability in carrier symptoms is related to X-chromosome inactivation patterns (lyonization), where different proportions of cells express the normal versus mutated X chromosome.

How are DMD carriers identified and confirmed? Carrier testing involves several approaches:

Linkage Analysis: Tracking the inheritance pattern of the X chromosome within a family when a known DMD case exists.
Direct Mutation Testing: Using the same genetic tests that identify DMD in affected individuals (MLPA, NGS, etc.) to detect the mutation in potential carriers.
Creatine Kinase (CK) Testing: Elevated CK levels can suggest carrier status, though normal levels don’t rule it out.
Muscle Biopsy with Immunostaining: Can show mosaic dystrophin expression in carriers, though this is rarely necessary with modern genetic testing.
X-chromosome Inactivation Studies: May help explain symptom variability in carriers but aren’t typically used for diagnostic purposes.

Carriers should be identified not only for reproductive planning but also for cardiac surveillance, as they have increased risk of cardiomyopathy.

Complications and Co-occurring Conditions

What gastrointestinal and nutritional complications are common in DMD? Gastrointestinal and nutritional issues are significant but sometimes overlooked aspects of DMD:

Dysphagia (Swallowing Difficulties): Progressive weakness of oropharyngeal muscles can lead to difficulties swallowing, increasing the risk of aspiration pneumonia and malnutrition.
Gastroparesis: Delayed gastric emptying can cause early satiety, nausea, bloating, and reflux.
Constipation: Reduced mobility, weakness of abdominal muscles, and some medications contribute to chronic constipation.
Gastroesophageal Reflux Disease (GERD): Common in DMD and can worsen with scoliosis and positional changes.
Nutritional Imbalances:
- Weight management issues (both overweight from reduced mobility and underweight from feeding difficulties)
- Calcium and vitamin D deficiency (increased by steroid use)
- Protein imbalances affecting muscle maintenance
Smooth Muscle Dysfunction: The digestive tract contains smooth muscle, which can be affected by lack of dystrophin.

Management includes dietary modifications, positioning strategies during meals, motility agents, stool softeners, and sometimes placement of feeding tubes (gastrostomy) in advanced cases.

What sleep disorders are associated with DMD? Sleep disturbances are common and multifactorial in DMD:

Sleep-Disordered Breathing: Weakened respiratory muscles can cause:
- Obstructive sleep apnea
- Hypoventilation during sleep (particularly REM sleep)
- Oxygen desaturation
Pain-Related Sleep Disruption: Musculoskeletal pain, particularly from contractures and positioning difficulties, can cause frequent awakening.
Periodic Limb Movements: More common in DMD than the general population.
Nocturnal Hypoxemia: Can occur before daytime respiratory symptoms become apparent.
Circadian Rhythm Disruptions: Reduced exposure to daylight due to mobility limitations may affect sleep timing.
Psychological Factors: Anxiety about breathing or positioning needs can contribute to insomnia.

Evaluation through polysomnography (sleep study) is recommended when symptoms suggest sleep disorders. Interventions include nocturnal non-invasive ventilation, positioning aids, pain management, and sleep hygiene practices.

Pain Management in DMD

How common is pain in DMD and how is it managed? Pain is increasingly recognized as a significant issue in DMD, affecting up to 85% of patients and often underreported:

Sources of Pain:
- Musculoskeletal pain from contractures, scoliosis, and positioning
- Gastrointestinal discomfort (constipation, reflux)
- Muscle cramps and spasms
- Pathological fractures due to osteoporosis
- Procedural pain from medical interventions
Assessment Challenges:
- Communication difficulties in some patients
- Overlap with other symptoms
- Adaptation to chronic pain leading to underreporting
Management Approaches:
- Physical Interventions: Physical therapy, stretching, massage, hydrotherapy, proper positioning, and orthotic devices
- Pharmacological Treatments:
  - NSAIDs (used cautiously due to potential cardiac effects)
  - Acetaminophen/paracetamol
  - Muscle relaxants for spasticity
  - Gabapentin or pregabalin for neuropathic components
  - Careful use of opioids for severe pain, with monitoring for respiratory effects
- Psychological Approaches: Cognitive behavioral therapy, relaxation techniques, distraction strategies
- Complementary Therapies: Acupuncture, TENS (transcutaneous electrical nerve stimulation), heat/cold therapy
Preventive Strategies:
- Maintaining range of motion to prevent contractures
- Regular position changes
- Optimal seating and sleeping surfaces
- Fracture prevention through bone health management

A proactive, multidisciplinary approach to pain management improves quality of life and psychological well-being in DMD.

Orthopedic Complications and Management

What are the orthopedic complications of DMD beyond scoliosis? DMD leads to numerous orthopedic complications that require specialized management:

Joint Contractures:
- Hip flexor, knee flexor, and ankle plantar flexion contractures are most common
- Elbow, wrist, and finger contractures develop in later stages
- Upper extremity contractures can significantly impact independence with assistive technology
Fractures:
- 20-25% of DMD patients experience fractures
- Long bone fractures (especially femur) and vertebral compression fractures
- Contributing factors include osteoporosis (from steroids and immobility), falls, and muscle imbalances
Hip Subluxation and Dislocation:
- Results from muscle imbalances around the hip joint
- Can cause significant pain and sitting difficulties
Osteoporosis and Osteopenia:
- Present in up to 80% of patients on long-term steroids
- Vertebral compression fractures can occur with minimal trauma
Lower Limb Deformities:
- Equinovarus (clubfoot-like) deformities
- Genu valgum (knock-knees) or genu varum (bow-legs)
- Rotational deformities of the tibia
Upper Extremity Issues:
- Shoulder subluxation
- Limited shoulder abduction and external rotation
- Wrist and hand deformities affecting function

What surgical interventions are commonly performed in DMD? Several surgical approaches may be considered at different disease stages:

Tendon Lengthening and Transfers:
- Achilles tendon lengthening for equinus contractures
- Hamstring lengthening for knee flexion contractures
- Iliotibial band release for hip abduction contractures
- Timing is crucial; generally performed in the late ambulatory phase
Scoliosis Surgery:
- Posterior spinal fusion with instrumentation is standard
- Typically performed when curves reach 20-30° in non-ambulatory patients
- Benefits include improved sitting comfort, respiratory function, and quality of life
Fracture Management:
- Often requires surgical fixation rather than casting due to the risk of increased muscle wasting during immobilization
- Intramedullary rods for long bone fractures
- Vertebroplasty or kyphoplasty for vertebral fractures
Hip Procedures:
- Soft tissue releases for contractures
- Reconstructive procedures for subluxation/dislocation when pain is significant
Foot and Ankle Surgery:
- Correction of equinovarus deformities
- Triple arthrodesis for severe deformities
Upper Extremity Procedures:
- Rarer, but may include releases to maintain function for wheelchair controls and assistive technology use

The decision to perform surgery always weighs benefits against risks, considering respiratory and cardiac status, bone density, and projected disease progression.

Respiratory Management in Advanced Stages

What advanced respiratory support options exist for later-stage DMD? Respiratory management becomes increasingly complex as DMD advances:

Non-invasive Ventilation (NIV) Progression:
- Starting with nocturnal-only support
- Advancing to part-time daytime use during respiratory infections or fatigue
- Eventually extending to continuous NIV (20+ hours/day)
- Various interfaces (nasal, full-face, nasal pillows) may be tried for comfort and effectiveness
Mechanical Insufflation-Exsufflation (MI-E):
- “Cough assist” devices become essential for airway clearance
- Typically used 2-4 times daily and during respiratory infections
- Protocols typically involve 3-5 cycles of insufflation/exsufflation per session
- Can be combined with manual techniques for enhanced effectiveness
Tracheostomy Ventilation:
- Considered when NIV is no longer effective or well-tolerated
- Provides more stable airway access and secretion management
- Comes with additional care requirements (stoma care, suctioning)
- Decision involves complex quality-of-life considerations and family preferences
Diaphragm Pacing:
- Electrical stimulation of the diaphragm
- Currently experimental in DMD but shows potential for some patients
Palliative Respiratory Management:
- Focused on comfort when full support is not desired
- May include oxygen therapy, positioning, and medication for dyspnea
- Protocols for acute respiratory distress management
Emergency Protocols:
- Detailed plans for respiratory emergencies
- Education for caregivers, schools, and emergency services
- “Go bags” with essential equipment and instructions

Decisions about respiratory support should ideally be discussed proactively before crises occur, with regular reassessment of goals and preferences as the disease progresses.

Steroid Management and Side Effects
