When it comes to treating Duchenne muscular dystrophy, the steroid dosing debate just got more nuanced. A new real-world study found that daily corticosteroids preserve motor function significantly longer than intermittent regimens — but at a steep cost to bone health and growth. The findings underscore that there's no one-size-fits-all answer, and the longer patients are followed, the starker the trade-offs become.
When it comes to treating Duchenne muscular dystrophy (DMD), the choice between daily and intermittent corticosteroid (CS) regimens has always involved trade-offs — and new long-term real-world data published in the Journal of Neurology, Neurosurgery & Psychiatry shows those trade-offs only deepen over time. The retrospective study followed 219 DMD patients across three neuromuscular centers in Belgium and the Netherlands for nearly a decade, comparing daily deflazacort against an intermittent 10-days-on/10-days-off regimen.
Daily CS therapy came out ahead on motor outcomes: patients walked nearly four years longer (median age 15.0 vs. 11.0 years) and were far more likely to retain upper-limb function into adulthood. But the intermittent group fared much better on growth and bone health — standing nearly 30 cm taller at age 18 and experiencing far fewer fractures.
By the Numbers
Why it matters: These findings reinforce that DMD steroid management can't be one-size-fits-all. Clinicians and families must weigh motor preservation against serious skeletal risks — and emerging therapies like vamorolone, which may offer motor benefits with a better safety profile, could soon reshape this calculus entirely.
