[Update on Duchenne muscular dystrophy]

Area of Science:

• Genetics and Molecular Biology
• Neurology
• Pediatrics

Background:

• Duchenne muscular dystrophy (DMD) is an X-linked autosomal recessive myopathy with a low incidence (1/3300).
• It presents with significant clinical variability and multi-organ involvement, including neuromuscular, respiratory, digestive, and metabolic systems.
• Symptoms typically manifest in childhood, leading to mobility limitations and early respiratory complications.

Purpose of the Study:

• To highlight the significant clinical variability and multi-organ involvement in Duchenne muscular dystrophy.
• To emphasize the critical role of Primary Care Physicians (PCPs) in managing DMD complications.
• To discuss current therapeutic approaches and their impact on life expectancy.

Main Methods:

• Review of existing literature on Duchenne muscular dystrophy.
• Analysis of clinical presentation, progression, and management strategies.
• Emphasis on the multidisciplinary approach to patient care.

Main Results:

• Respiratory complications significantly reduce life expectancy in DMD patients.
• Corticosteroids and emerging gene therapies are extending the lifespan of individuals with DMD.
• The PCP plays a crucial role in coordinating care and managing complications.

Conclusions:

• Duchenne muscular dystrophy is a complex, multi-system disorder requiring lifelong management.
• Early diagnosis and proactive management by PCPs are essential for improving patient outcomes.
• Ongoing research in gene therapy offers hope for more effective treatments in the future.
