Our results show a linear relationship between serum CPK and serum ALT and AST and a logarithmic relationship between serum enzyme levels and age for boys with DMD. Progression of weakness is steady, and limb flexion contractures and scoliosis develop in nearly all children. Update: The International Conference on Duchenne and Becker muscular dystrophy has been cancelled due to given the current alert situation related to Coronavirus. Mechanical ventilation is used to treat respiratory failure, but can affect cardiac function. But Becker muscular dystrophy starts later -- around the teen years. The Duchenne and Becker muscular dystrophies (as well as a third intermediate form) are caused by mutations of the dystrophin gene and are therefore named dystrophinopathies. Investigational therapies for Duchenne dystrophy and Becker dystrophy include gene therapy, creatine, myostatin inactivation, skeletal muscle progenitors, and the antioxidant idebenone. The usual presenting symptom in neonates is a vesicular eruption that appears between the 1st and 3rd week of life. Inheritance pattern and molecular understanding are really HY for USMLE. Children frequently toe walk and have a waddling gait and lordosis. Use of prednisone or deflazacort in Becker dystrophy has not been adequately studied.

For patients with certain mutations, eteplirsen or golodirsen, despite limited evidence of clinical benefit, may be used as well. Patients have significant, progressive weakness that causes severe disability, including difficulty walking, frequent falls, dilated cardiomyopathy, and early death due to respiratory insufficiency. You can download PDF version of this article and use it for offline purposes as per citation notes. People with Duchenne or Becker are born with a change - or mutation - in the gene that produces dystrophin, a protein that protects muscles. Female carriers may have asymptomatic elevated creatine kinase levels and possibly calf hypertrophy. The drugs mask an exon so that it will be skipped and ignored during protein production, allowing the production of a dystrophin protein that, while not normal, is functional and may lessen symptoms so that they are more like those in boys with the less severe Becker muscular dystrophy. … They are both caused by mutations in the DMD gene, which encodes the protein dystrophin.
