Corticosteroids in Duchenne Muscular Dystrophy
Corticosteroids in Duchenne muscular dystrophy: evidence on benefits, side effects, and the treatment questions families can bring to clinicians.
Corticosteroids have long been part of Duchenne muscular dystrophy care. Prednisone and deflazacort are the traditional options, with newer steroid-related therapies also discussed in recent years. They are not a cure, but evidence supports modest benefits for many patients across mobility, breathing, and the heart.
What corticosteroids aim to do
Corticosteroids reduce inflammation and appear to help preserve muscle strength for a period of time in many boys with Duchenne. The Cochrane review found evidence that glucocorticoids improve muscle strength and function over the short to medium term, while adverse effects are common. (Cochrane, Corticosteroids for DMD)
The balance is the issue. A medicine can help function and still create problems that matter.
Common side effects
Side effects may include weight gain, changes in growth, mood or behavior changes, high blood pressure, cataracts, bone fragility, delayed puberty, glucose issues, and adrenal suppression. The 2018 care considerations describe endocrine and bone monitoring as part of DMD care. (Birnkrant et al., Lancet Neurology 2018 Part 3)
Families should not stop corticosteroids suddenly without clinical guidance because adrenal suppression can be dangerous.
Different steroid choices
Prednisone and deflazacort have both been used in DMD. Differences in side-effect profiles can influence clinician recommendations. Some newer agents have been developed to try to retain benefits while reducing some harms, but their role depends on regulatory status, patient factors, and clinician judgment.
This site does not recommend one drug over another. The useful question is how the care team weighs expected benefit, risks, growth, behavior, bone health, heart and lung status, and family priorities.
What families can ask
Families may want to ask: What is the goal of this medicine for this child? How will benefit be measured? What side effects are most important to watch? How will bone health, growth, blood pressure, eyes, and adrenal suppression be monitored? What happens during illness or surgery?
The answers should be individualized.
What is still uncertain
Steroids remain important, but there is no one perfect regimen. Dose, timing, daily versus intermittent schedules, and newer options are areas where practice can vary. Evidence should be interpreted with a neuromuscular team.
