Summary
Recent advancements offer new hope for Duchenne muscular dystrophy (DMD) patients with seven novel medications approved since 2016. These treatments target different pathways to combat progressive muscle wasting in this severe genetic disorder.
Area of Science:
- Neurology
- Genetics
- Pharmacology
Background:
- Duchenne muscular dystrophy (DMD) is a severe X-linked muscle wasting disease.
- Historically, treatment options were limited to glucocorticoid steroids.
- Recent years have seen significant advancements in pharmacologic interventions for DMD.
Purpose of the Study:
- To review novel pharmacologic interventions for Duchenne muscular dystrophy.
- To summarize mechanisms of action, safety, and efficacy of new DMD medications.
- To provide an overview of recent FDA-approved treatments for DMD.
Main Methods:
- Literature review of recently approved DMD medications.
- Analysis of drug mechanisms targeting DMD disease pathways.
- Synthesis of safety data and motor function impact evidence.
Main Results:
- Seven new medications approved by the FDA since 2016.
- Includes novel glucocorticoids (vamorolone), exon-skipping therapies (eteplirsen, golodirsen, vitolarsen, casimersen), gene therapy (delandistrogene moxeparvovec), and HDAC inhibitors (givinostat).
- These therapies target various aspects of the DMD disease process.
Conclusions:
- Novel medications offer diverse therapeutic strategies for DMD.
- Understanding mechanisms, safety, and functional outcomes is crucial.
- These advancements represent a significant shift in DMD treatment paradigms.

Satellite Stem Cells and Muscular Dystrophy
2.6K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Myasthenia Gravis: Overview and Treatment
3.4K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Cystic Fibrosis: Management
620
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Cardiomyopathy II: Dilated Cardiomyopathy
767
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
1.4K
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
