Patients with Duchenne muscular dystrophy in Brazil

Area of Science:

  • Neurology
  • Rare Diseases
  • Public Health

Background:

  • Duchenne muscular dystrophy (DMD) is a progressive neuromuscular disorder.
  • Early intervention is crucial for managing DMD.
  • Healthcare disparities can limit optimal treatment access for rare diseases.

Purpose of the Study:

  • To identify unmet needs and challenges in Duchenne muscular dystrophy care.
  • Compare care in Brazil's public vs. private health systems.

Main Methods:

  • Cross-sectional observational study using the Delphi method.
  • Ten neurologists specialized in DMD participated in consensus surveys.
  • Descriptive statistics were used for data analysis.

Main Results:

  • Public system diagnostic delay averaged 25 months vs. 10 months privately.
  • Public system lacks funding for genetic testing, delays corticosteroid treatment, and offers limited multidisciplinary care.
  • Public system patients lost ambulation earlier and had shorter life expectancy (19-20 years vs. 26-27 years).

Conclusions:

  • Significant disparities exist in Brazilian Duchenne muscular dystrophy care between public and private systems.
  • Worse outcomes observed in the public health system.
  • Improved access to genetic testing and early multidisciplinary care is vital for enhancing quality of life and survival.

Satellite Stem Cells and Muscular Dystrophy

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...

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Cardiomyopathy II: Dilated Cardiomyopathy

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,...

Cystic Fibrosis: Management

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.
Sinus disease and chronic...

Myasthenia Gravis: Overview and Treatment

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...
