Medication
Steroids (prednisone or deflazacort) are often routinely prescribed for Duchenne muscular dystrophy, as they slow the decline in muscle strength and mobility over a certain period of time and prevent or postpone the development of complications. However, there are many possible side-effects which must be carefully managed.
Procedures
Glucocorticoids, more precisely prednisone and deflazacort, are the main drug treatment for DMD. They have been used for over two decades and the benefits are well known now. They are the only medication that has been shown to increase muscular strength.

Can muscular dystrophy be passed from father to son?
Inheriting muscular dystrophy. You have two copies of every gene (with the exception of the sex chromosomes). You inherit a copy from one parent, and the other copy from the other parent. If one or both of your parents has a mutated gene that causes MD, it can be passed on to you.
What is dystrophin protein?
In Becker's muscular dystrophy, the dystrophin protein is smaller and partially functional, resulting in less severe illness. In DMD patients, as mentioned earlier, the mutated gene manifests deletions, duplications and point mutations which interrupt the genetic information's reading frame.
What happens if you don't have dystrophin?
The absence of dystrophin leads to mechanical damage of the sarcolemma, loss of calcium homeostasis, and progressive degeneration of muscle fibres. The dystrophin gene is the largest gene found in humans and accounts for approximately 0.1% of the total human genome.
How long does a DMD patient live?
Eagle mentions that in 1960, the average life expectancy for DMD patients was 14.4 years, which by 1990 had risen to 19.3 years with the use of corticosteroids, antibiotic therapy and intensive care treatment. Nowadays it has risen to 24.5 years, probably due to the use of non-invasive ventilation (8, 14).
Can DMD patients walk?
Currently, many physicians keep up the treatment, even after the DMD patient has lost the ability to walk, with the objectives of preserving the function of the upper extremities, reducing the progression rate of scoliosis, and slowing the impairment of respiratory and cardiac function (2).
Do DMD patients need corticosteroids?
In summary, there is substantial evidence to recommend the use of corticosteroids to all DMD patients with the objective of preserving walking time as long as possible and reducing lung, heart and orthopaedic complications (2). Naturally, the adverse effects of the corticosteroid treatment must also be considered.

Duchenne muscular dystrophy ( DMD) affects the muscles, leading to muscle wasting that gets worse over time. DMD occurs primarily in males, though in rare cases may affect females. The symptoms of DMD include progressive weakness and loss (atrophy) of both skeletal and heart muscle. Early signs may include delayed ability to sit, stand, ...
Why do boys with DMD have breathing problems?
By the early teens, most boys with DMD are using a wheelchair. Breathing problems occur due to weakness of the diaphragm and the other muscles around the lungs. Scoliosis and tight joints ( contractures) may develop as muscle loss gets worse.
What causes muscle weakness in children?
Heart and breathing problems also begin in the teen years and lead to serious, life threatening complications. DMD is caused by genetic changes ( DNA variants) in the DMD gene.

Is DMD inherited?
DMD is inherited in an X-linked recessive pattern and may occur in people who do not have a family history of DMD. Diagnosis of DMD is based on the symptoms, clinical exam, and the result of a biopsy to remove a small piece of muscle for examination under a microscope.
Is Duchenne muscular dystrophy a recessive disorder?
Duchenne muscular dystrophy (DMD) is inherited in an X-linked recessive pattern. [1] . X-linked means that the gene for the condition is located on the X- chromosome, one of the sex chromosomes. In males (who have only one X chromosome ), one altered copy of the gene is enough to cause the condition.
What is the best treatment for Duchenne muscular dystrophy?
Steroid therapy is a standard treatment for Duchenne, while other treatments will depend on your specific symptoms and condition. Steroids are a mainstay of treatment for Duchenne muscular dystrophy. Eldad Carin/Stocksy. Duchenne muscular dystrophy is a genetic, progressive condition that causes loss of muscle function over time.
What is the treatment for Duchenne?
Corticosteroids, referred to as steroids for short, are the main drug treatment for Duchenne. Among doctors who treat the condition, “we all agree that steroids are the cornerstone of Duchenne management,” says Vamshi K. Rao, MD, a pediatric neurologist and the codirector of the Muscular Dystrophy Association Clinic at Lurie Children’s Hospital in Chicago.

What is the name of the enzyme that covers up the exons of the dystrophin protein?
Newer agents called antisense oligonucleotides are now approved by the FDA. Antisense oligonucleotides are small pieces of DNA that are used to "mask" (cover up) the exon that needs to be skipped when making the dystrophin protein. This allows the rest of the gene to be be pieced together correctly.
What is the cause of DMD?
DMD is caused by mutations in the DMD gene. When a gene exon is missing (for example, exon 51 or 53), cells do not have the proper instructions to make dystrophin, which leads to a type of muscle damage that causes DMD. Dystrophin helps to strengthen and protect muscles.
How does a scoliosis medication help?
These medicines are beneficial as they can help improve motor skills, muscle strength, lung function, and delay the loss of the ability to walk unaided. They may also help to reduce the risk of scoliosis and improve heart function and survival, although not all studies have found an association.
Can antisense oligonucleotides cure DMD?
Not all patients respond to, or are candidates for antisense oligonucleotides. They are not a cure for DMD, but may help improve muscle symptoms.

MD patients who experience weakness in the facial and throat muscles may benefit from speech therapy to teach them how to maximize their muscle strength. Some methods include slowing the pace of their speech, pausing more between breaths, 3 and using specialized communication equipment.
Why do MD patients have difficulty breathing?
Respiratory Therapy. Because the body relies on muscles such as the diaphragm to breathe, weakened muscles from MD may affect breathing. Many people with MD do not realize they have lost respiratory strength until they have difficulty coughing or an infection leads to pneumonia.
Does prednisone help with weakness?
Studies show that daily treatment with prednisone can increase muscle strength and respiratory function and slow the progression of weakness in MD. A new glucocorticoid treatment called vamorolone is being studied in boys with DMD.
Does exon skipping cure DMD?
In exon skipping, more muscle protein is available and usable, even though it is shorter than the normal protein. FDA approved eteplirsen for treatment of DMD in 2016, 8 golodirsen in 2019, 9 and viltolarsen in 2020. 10 These treatments require weekly intravenous injection and do not cure DMD.
