Definitions
- the present invention relates to the use of purified natural 20-hydroxyecdysone (20E) or synthetic derivatives for the treatment of myopathies and in particular muscular dystrophies of genetic origin.
- Myopathies are diseases that directly affect the muscle. There are different forms depending on the manifestations and mechanisms of the muscular involvement. Two categories exist: genetic myopathies and acquired myopathies.
- muscular dystrophies muscle dystrophies of Duchenne and Becker, muscular dystrophies of the belts and facioscapulo-humeral dystrophy), or congenital dystrophies,
- metabolic myopathies such as glycogenoses and lipidoses as well as mitochondrial myopathies
- myotonic dystrophies such as Steinert myopathy (DM1),
- Acquired myopathies include:
- Myopathies are manifested by progressive or stable muscle weakness. They are generally characterized by a loss of muscle mass (atrophy). During the evolution of the disease, the muscle tissue is gradually replaced by fibrous tissue (fibrosis).
- genes involved in muscular dystrophies Most often, they are genes responsible for the synthesis of proteins located in the membrane of muscle cells or linked to it and essential for the maintenance of architecture and muscle function. For example :
- DMD Duchenne muscular dystrophy
- BMD Becker muscular dystrophy
- dysferlin sarcoglycans are involved in muscular dystrophies of belts
- DMD congenital muscular dystrophies
- BMD congenital muscular dystrophies
- DMD is the most common muscular dystrophy. It affects 1 in 3500 boys and results from mutations affecting the dystrophin gene, located on the X chromosome.
- a less severe form, BMD also involves the dystrophin gene and affects 1 in 18000 boys.
- DMD is a condition serious genetics that affects the entire musculature. In this disease, the fragility of the muscle fibers leads to their destruction resulting in necrosis of the muscle tissue. When regeneration mechanisms are exceeded, degeneration prevails resulting in a loss of muscle strength and an intolerance to effort (Barnabei et al 201 1). The muscle fibers are then replaced by connective tissue (fibrosis). Muscle weakness gradually gains the lower limbs of children over 3 years old. The disease develops later in the muscles of the back, the upper limbs and finally the respiratory muscles.
