Assessing the Benefits and Harms Associated with Early Diagnosis from the Perspective of Parents with Multiple Children Diagnosed with Duchenne Muscular Dystrophy
O Battacharria et al, IJNS, April 15, 2024

From the abstract: " Duchenne muscular dystrophy (DMD) is a rare neuromuscular disorder diagnosed in childhood. Limited newborn screening in the US often delays diagnosis. With multiple FDA-approved therapies, early diagnosis is crucial for timely treatment but may entail other benefits and harms. Using a community-based survey, we explored how parents of siblings with DMD perceived early diagnosis of one child due to a prior child’s diagnosis. We assessed parents’ viewpoints across domains including diagnostic journey, treatment initiatives, service access, preparedness, parenting, emotional impact, and caregiving experience."

Newborn screening for Duchenne muscular dystrophy: the perspectives of stakeholders.
Charli Ji et al. Lancet Reg Health West Pac 2024 3 101049

From the abstract: "Participants included 50 caregivers and 26 HCPs (68.5% and 53.1% response rate respectively). Most caregivers (40/50, 80%) perceived net benefits of DMD NBS and highlighted an early diagnosis as actionable knowledge, even with the current paucity of disease modifying therapies. This knowledge was valued to enable access to multidisciplinary supportive care (29/50, 58%), clinical trials (27/50, 54%), psychological support (28/50, 56%), inform reproductive planning (27/50, 54%), and facilitate financial planning based on the future needs of their child (27/50, 54%).

Diagnosis and Management of Myotonic Dystrophy Type 1
J Hartman et al, JAMA March 11, 2024

From the article: " Myotonic dystrophy type 1 is the most common form of muscular dystrophy. A recent genetic prevalence study of 50?382 consecutive births from the New York state newborn screening program estimated prevalence to be approximately 1:2100 individuals. This estimate is substantially higher than previously reported global estimates, which ranged from 5 to 20 per 100?000 individuals.2 Additional prevalence studies are needed with representative populations in other regions of the world. In an analysis of 679 patients in a US registry, individuals with myotonic dystrophy type 1 had a 7-year delay from symptom onset to diagnosis."

Spending on Targeted Therapies for Duchenne Muscular Dystrophy
L Bendicksen et al, JAMA, March 11, 2024

From the article: "Duchenne muscular dystrophy–targeted therapies with limited evidence of clinical efficacy have cost the US health care system more than $3 billion. Most of this spending was for eteplirsen, the efficacy of which has yet to be determined in a confirmatory trial more than 7 years after the drug’s accelerated approval. This analysis sheds light on controversies relating to drugs’ limited preapproval evidence of efficacy, high prices, and delayed confirmatory trials. "
