Duchenne muscular dystrophy (DMD) is a complex genetic disorder requiring a comprehensive and multidisciplinary approach to care. Thanks to significant advancements in medical fields such as cardiology and pulmonology, individuals diagnosed with DMD today are living longer and fuller lives, often extending well into adulthood. Effective DMD treatment necessitates the coordination of numerous specialized assessments and interventions, all aimed at maximizing patient function and enhancing their overall quality of life. Finding the right Duchenne Muscular Dystrophy Doctor and care team is the first crucial step in navigating this journey.
The cornerstone of DMD management lies in utilizing available treatments to alleviate discomfort, sustain bodily functions, and extend life expectancy. Physicians at MDA Care Centers specialize in creating personalized care plans that address the diverse medical and supportive needs of DMD patients. These plans are designed to be dynamic and adapt to the evolving needs of individuals as the condition progresses.
Understanding Anesthesia Considerations with Your Duchenne Muscular Dystrophy Doctor
One critical aspect your Duchenne muscular dystrophy doctor will emphasize is the heightened sensitivity to anesthesia in individuals with DMD. Patients may experience unexpected adverse reactions to certain anesthetic agents. Therefore, it is paramount that any surgical team is fully informed about a patient’s DMD diagnosis. This awareness allows for proactive measures to prevent complications or ensure their swift and effective management should they arise. Preoperative evaluations by specialists in pulmonology, anesthesia, and cardiology are essential for DMD and Becker muscular dystrophy (BMD) patients prior to undergoing any surgical procedures. These evaluations help to identify potential risks and tailor the anesthesia plan accordingly, ensuring patient safety throughout any necessary procedures.
Mobility Aids and Your Duchenne Muscular Dystrophy Doctor: Braces, Standing Frames, and Wheelchairs
Your Duchenne muscular dystrophy doctor will likely discuss various mobility aids to support function and independence. Braces, or orthoses, play a vital role in supporting the ankle and foot, and some designs extend to provide support above the knee. Ankle-foot orthoses (AFOs) are frequently recommended for nighttime use to prevent foot drop and maintain the stretch of the Achilles tendon while sleeping.
Standing, even with minimal weight-bearing, is highly beneficial for individuals with DMD. It promotes improved circulation, strengthens bones, and helps maintain spinal alignment. Standing walkers or standing frames can provide the necessary support for individuals with DMD to stand safely. Furthermore, some advanced wheelchairs are designed to elevate the user to a standing position, offering added convenience and therapeutic benefits.
While the transition to wheelchair use can be emotionally challenging, it’s a common progression in DMD, often becoming necessary around the age of 12. Typically, wheelchair use is gradual, starting with longer distances, such as at school or in shopping centers, while maintaining walking at home for a period. It’s important to recognize that wheelchairs are not a symbol of limitation, but rather tools that enhance mobility, energy levels, and independence for many individuals with DMD. Discussing these transitions openly with your Duchenne muscular dystrophy doctor and care team can help manage expectations and ensure a smooth adjustment.
In addition to wheelchairs, a range of other mobility and positioning aids can significantly assist both patients and caregivers. Simple aids like transfer boards facilitate safer and easier movement in and out of wheelchairs. Mechanical lifts, shower chairs, and electronic beds are also valuable tools that can enhance comfort and ease of caregiving. Your Duchenne muscular dystrophy doctor and occupational therapist can provide guidance on selecting and utilizing the most appropriate aids to meet individual needs.
Cardiac Care and the Duchenne Muscular Dystrophy Doctor’s Role
Cardiac health is a major concern in DMD, and proactive cardiac care is a critical component of management overseen by your Duchenne muscular dystrophy doctor. The American Academy of Pediatrics recommends that all individuals with DMD undergo a comprehensive cardiac evaluation by a specialist, starting in early childhood. This initial evaluation, including an electrocardiogram (ECG) and noninvasive imaging, should be repeated at least every other year until age 10, and annually thereafter or sooner if symptoms of heart weakness arise, such as shortness of breath or fluid retention.
Female carriers of DMD also face an elevated risk of developing cardiomyopathy and should be monitored closely. Cardiac evaluations, including cardiac MRI, are recommended for female carriers starting in late adolescence or early adulthood, and should be repeated at least every five years, or sooner if symptoms occur.
Pharmacological interventions play a crucial role in managing cardiac complications in DMD. Duchenne muscular dystrophy doctors often prescribe angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), and beta-blockers to slow the progression of cardiac muscle deterioration. These medications are most effective when initiated early, ideally as soon as abnormalities are detected on an echocardiogram, even before symptoms manifest. Some evidence suggests that corticosteroids may also delay the onset of cardiomyopathy. Additionally, mineralocorticoid receptor antagonists like eplerenone show promise in mitigating the decline in heart function, although further research is needed to solidify these findings. Regular consultations with a cardiologist, guided by your Duchenne muscular dystrophy doctor, are essential for proactive cardiac management.
Managing Contractures with Guidance from Your Duchenne Muscular Dystrophy Doctor
Maintaining flexibility, posture, and mobility are key strategies in minimizing the impact of DMD, and your Duchenne muscular dystrophy doctor will emphasize these aspects of care. As muscle deterioration progresses in DMD, joint fixations known as contractures are a common development. If left unaddressed, contractures can become severe, leading to significant discomfort and restricted movement in joints such as knees, hips, feet, elbows, wrists, and fingers.
However, proactive management can significantly postpone and minimize contractures. Regular range-of-motion exercises are crucial in maintaining tendon length and delaying contracture development. A physical therapist, working in collaboration with your Duchenne muscular dystrophy doctor, can provide essential guidance on performing these exercises correctly and effectively.
Braces also play a key role in maintaining limb flexibility and delaying contractures. In cases where contractures have advanced, surgical interventions may be necessary to release them. Tendon release procedures, such as heel cord surgery, are often performed to address ankle and other contractures, frequently while the child is still able to walk. Post-surgery, lower leg braces are typically required to maintain the corrected position and support ongoing flexibility.
Diet and Nutrition: Consulting Your Duchenne Muscular Dystrophy Doctor and Dietitian
While there are no specific dietary interventions that directly target DMD, your Duchenne muscular dystrophy doctor and a registered dietitian will provide essential nutritional guidance. A balanced diet, similar to recommendations for any growing child, is generally advised, with some specific considerations. Ensuring adequate intake of dietary calcium and vitamin D, through dairy products, calcium-rich foods, supplements, and safe sun exposure, is often recommended to support bone health, particularly for those on corticosteroid therapy.
Given the potential for malnutrition and weight imbalances in DMD, especially with glucocorticoid treatment, regular consultations with a nutritionist or dietitian are recommended at each clinic visit. For individuals using power wheelchairs, taking prednisone, or with reduced physical activity, weight management becomes particularly important. Excessive weight gain can place added strain on weakened skeletal muscles and the heart. In these cases, a controlled caloric intake may be advised to maintain a healthy weight, and your Duchenne muscular dystrophy doctor can offer specific recommendations.
Constipation can be a significant issue due to immobility and weakened abdominal muscles. A diet rich in fluids and fiber, emphasizing fresh fruits and vegetables, is crucial for promoting bowel regularity. Dysphagia, or difficulty swallowing, can also develop in DMD. If swallowing difficulties are suspected, referral to a speech and language therapist for a swallowing assessment is essential. In cases of severe dysphagia, weight loss, dehydration, malnutrition, or aspiration risk, a gastrostomy tube (feeding tube) may be necessary. Individuals on prednisone or with heart conditions may also require a sodium-restricted diet, which should be managed in consultation with their Duchenne muscular dystrophy doctor and dietitian.
Exercise and Physical Activity: Recommendations from Your Duchenne Muscular Dystrophy Doctor
Exercise is an important aspect of overall health in DMD, but it requires careful consideration and guidance from your Duchenne muscular dystrophy doctor. While exercise can help maintain cardiovascular health and well-being, excessive exertion can potentially damage muscles in muscular dystrophy. Therefore, consulting with your doctor to determine the appropriate level and type of exercise is crucial. Moderate exercise is generally encouraged, but activities that lead to exhaustion should be avoided.
Swimming and water-based exercises (aquatic therapy) are often recommended as excellent ways to maintain muscle tone without placing undue stress on muscles. The buoyancy of water provides support and reduces the risk of strain or injury. It is imperative to undergo a cardiac evaluation before initiating any exercise program to ensure safety. Your Duchenne muscular dystrophy doctor and physical therapist can collaborate to create a safe and effective exercise plan tailored to individual needs and abilities.
Addressing Cognitive and Behavioral Considerations with Your Duchenne Muscular Dystrophy Doctor
Cognitive and behavioral disorders are more prevalent in children with DMD, and your Duchenne muscular dystrophy doctor plays a crucial role in identifying and managing these challenges. Children suspected of having learning disabilities should be evaluated by a developmental or pediatric neuropsychologist. This can be facilitated through the school system’s special education department or at a medical center, often through a referral from the MDA Care Center.
DMD is associated with higher rates of autism spectrum disorders, attention deficit hyperactivity disorder (ADHD), anxiety, and depression. These conditions may require appropriate medical management and behavioral therapies. Open communication with your Duchenne muscular dystrophy doctor about any cognitive or behavioral concerns is essential for timely intervention and support.
Medications and the Duchenne Muscular Dystrophy Doctor’s Prescriptions
Medications are a cornerstone of DMD management, and your Duchenne muscular dystrophy doctor will carefully prescribe and monitor these therapies. As mentioned previously, medications to reduce cardiac workload are often prescribed. Corticosteroids are considered the mainstay of pharmacological treatment for DMD, as they have demonstrated effectiveness in slowing disease progression. Initiating corticosteroid treatment before significant physical decline is generally recommended.
Prednisone and deflazacort are the primary corticosteroids used in DMD treatment. Deflazacort (Emflaza) is an oxazoline derivative of prednisone approved by the FDA in 2017 specifically for DMD. Studies have shown that corticosteroids can lead to significant increases in muscle strength and improvements in timed muscle function and pulmonary function. They also reduce the risk of scoliosis and delay the loss of ambulation. Some studies indicate that glucocorticosteroids may improve survival rates in DMD, although research in this area is ongoing.
Chronic corticosteroid use, while beneficial, can lead to side effects such as weight gain, short stature, acne, behavioral changes, osteoporosis, and fractures. Therefore, regular monitoring by your Duchenne muscular dystrophy doctor is essential, including periodic spine imaging to detect asymptomatic vertebral fractures. Children who develop fractures should be referred to a pediatric endocrinologist or bone specialist for further management. Abruptly stopping corticosteroid treatment can lead to serious complications, and any withdrawal should be carefully managed using established protocols like the PJ Nicholoff Steroid Protocol.
In addition to corticosteroids, several newer medications target specific genetic mutations in DMD. Eteplirsen, Ataluren (PTC124), Vyondys 53, and Viltepso are exon-skipping drugs approved for specific DMD mutations. Eteplirsen, approved in 2016, targets exon 51 skipping. Ataluren is approved in Europe and the UK for nonsense mutations. Vyondys 53 and Viltepso, both approved more recently by the FDA, target exon 53 skipping. These medications aim to increase dystrophin production and are applicable to subsets of the DMD population with specific genetic profiles. Your Duchenne muscular dystrophy doctor will determine if these targeted therapies are appropriate based on genetic testing.
Immunizations: Protecting DMD Patients Under the Guidance of Your Duchenne Muscular Dystrophy Doctor
Children with DMD should receive all routine vaccinations recommended by the US Centers for Disease Control and Prevention (CDC). It’s important to discuss the timing of vaccinations with your Duchenne muscular dystrophy doctor, as some vaccines should be administered before starting glucocorticoid treatment due to potential contraindications in patients receiving high-dose corticosteroids.
Physical and Occupational Therapy: Essential Components of Care Coordinated by Your Duchenne Muscular Dystrophy Doctor
Physical therapy is a cornerstone of DMD treatment, and your Duchenne muscular dystrophy doctor will refer you to a physical therapist for comprehensive evaluation and a tailored program. The primary goals of physical therapy are to maximize joint mobility, prevent contractures and scoliosis, and maintain functional abilities for as long as possible. Physical therapy focuses on mobility and strengthening large muscle groups where appropriate.
Occupational therapy complements physical therapy by focusing on specific activities and daily functions. Occupational therapists assist with adapting tasks related to work, recreation, and daily living, such as dressing, eating, or using technology. Both physical and occupational therapy are integral to a holistic DMD care plan coordinated by your Duchenne muscular dystrophy doctor.
Respiratory Care and the Duchenne Muscular Dystrophy Doctor’s Team
Respiratory muscle weakness is a significant aspect of DMD progression, requiring proactive respiratory care guided by your Duchenne muscular dystrophy doctor and a respiratory therapist or pulmonologist. As breathing muscles weaken, maintaining clear airways becomes crucial. Cough assist devices or manual assisted coughing techniques, performed by a caregiver, can help clear bronchial secretions.
Assisted ventilation may become necessary to support adequate airflow into and out of the lungs. Noninvasive ventilation, delivered through a mask, nosepiece, or mouthpiece, is typically the first step. Initially, noninvasive ventilation may only be required part-time, often during sleep. However, as respiratory weakness progresses, round-the-clock noninvasive ventilation may be needed. In some cases, individuals may choose to transition to invasive ventilation via a tracheostomy, a surgical opening in the trachea. Your Duchenne muscular dystrophy doctor and respiratory specialists will guide decisions regarding ventilation strategies based on individual needs and disease progression.
Spinal Curvatures and Orthopedic Management by Your Duchenne Muscular Dystrophy Doctor
Spinal curvatures, including scoliosis (side-to-side curve) and kyphosis (“hunchback” curve), are common in DMD and require careful monitoring and management by your Duchenne muscular dystrophy doctor and orthopedic specialists. Scoliosis typically develops after wheelchair use becomes full-time. Severe scoliosis can impact sitting, sleeping, and breathing.
Preventive measures, including exercises to maintain spinal alignment and advice on optimal sitting and sleeping positions from a physical therapist, are crucial. Spine-straightening surgery, involving the insertion of metal rods and hooks, may be necessary to correct severe scoliosis. Surgery is often performed during adolescence. Regular orthopedic assessments, guided by your Duchenne muscular dystrophy doctor, are essential to monitor spinal health and determine appropriate interventions.
Standards of Care and the Duchenne Muscular Dystrophy Doctor’s Expertise
DMD care is guided by established standards and guidelines, and your Duchenne muscular dystrophy doctor will ensure that your care plan aligns with these best practices. The Centers for Disease Control and Prevention (CDC) Care Considerations for Duchenne muscular dystrophy were updated in 2018, providing comprehensive recommendations for management. The American Academy of Neurology (AAN) guidelines on corticosteroid treatment were updated in 2016.
General recommendations for medical care in DMD were initially issued in 2010 by the DMD Care Considerations Working Group under the auspices of the US CDC. Family-friendly versions of these guidelines are also available from organizations like TREAT-NMD. Guidelines for anesthesia and sedation in DMD were released by the American College of Chest Physicians in 2007. Recommendations for cardiovascular health supervision in BMD and DMD carriers were issued by the American Academy of Pediatrics in 2005. Respiratory care guidelines were released by the American Thoracic Society in 2004. Staying informed about these guidelines and working closely with a knowledgeable Duchenne muscular dystrophy doctor are essential for optimal DMD management.
