Duchenne Muscular Dystrophy Prevalence Increases, While Incidence Remains Steady


In the first study of its kind involving Duchenne Muscular Dystrophy (DMD) in the U.S., researchers from the Deerfield Institute found that while the number of new cases has remained stable, there has been an uptick in prevalence — largely attributed to enhanced treatments and longevity. The study, which is titled “Duchenne Muscular Dystrophy Prevalence in the U.S.: A Novel Incidence-Based Modeling Approach Using System Dynamics”, is scheduled for Poster Session ll on Monday, May 20 at the ISPOR 2019 annual meeting in New Orleans.

DMD, a genetic disorder characterized by progressive muscle degeneration and weakness, is caused by an absence of Dystrophin, a protein that helps keep muscle cells intact. Symptom onset is in early childhood, typically between ages 3 and 5. The disease primarily affects boys, but in rare cases it can affect girls.
