What is the diagnosis and treatment for Amyotrophy (Muscular Atrophy)?

From the Guidelines

Amyotrophy patients, particularly those with amyotrophic lateral sclerosis (ALS), should be managed with a palliative approach from diagnosis, emphasizing patient autonomy, dignity, and quality of life. This approach is crucial as ALS is a relentlessly progressive neurodegenerative condition 1. The management of amyotrophy depends on the underlying cause, which can include diabetic amyotrophy, neuralgic amyotrophy, and motor neuron diseases like ALS.

Treatment Considerations

• For patients with ALS, fractionating and enriching meals with energy or deficient nutrients is recommended, especially in cases of muscular fatigue and long-lasting meals 1.
• In ALS patients with moderate dysphagia, dietetic counseling to adapt the texture of solid and liquids can facilitate swallowing and avoid aspiration 1.
• Postural maneuvers, such as the chin-tuck posture, should be recommended to protect the airway during swallowing in ALS patients with moderate dysphagia 1.
• Physical therapy is essential to maintain muscle strength and range of motion, and pain management with medications like gabapentin or pregabalin may be necessary.

Quality of Life and Supportive Care

• Early diagnosis and treatment are crucial to prevent permanent muscle damage, and any unexplained muscle weakness or wasting should prompt immediate medical evaluation.
• Recovery time varies significantly among different forms of amyotrophy, with some forms like neuralgic amyotrophy potentially improving over months to years, while progressive conditions like ALS require ongoing supportive care.
• Patient education, regular exercise, and physical therapy are cornerstone treatments for managing symptoms and improving quality of life 1.

Clinical Decision Making

Given the complexity and variability of amyotrophy, clinical decision-making should prioritize the most recent and highest quality evidence, focusing on improving morbidity, mortality, and quality of life outcomes. In the absence of strong evidence, decisions should be made with caution, considering the specific context and needs of each patient.

From the Research

Definition and Overview of Amyotrophy

• Amyotrophy, also known as amyotrophic lateral sclerosis (ALS), is a progressive neurodegenerative disease that affects the upper and lower motor neurons, leading to a loss of muscle control and eventually paralysis 3.
• The exact cause of ALS is still unknown, but research has identified several cellular processes that occur after disease onset, including mitochondrial dysfunction, protein aggregation, and inflammation 3.

Treatment Options for Amyotrophy

• Riluzole is the only disease-modifying drug approved for the treatment of ALS, and it has been shown to modestly prolong survival 4, 5, 6.
• The use of riluzole has been associated with a significant improvement in survival, with a median survival increase of 2-3 months 4 and 7 months 6.
• Other treatment options, such as stem cell therapy, are being explored, but more research is needed to determine their effectiveness 7.

Prognostic Factors and Survival

• The prognosis for ALS patients varies widely, with some patients surviving for only a few months and others living for decades 3.
• The use of riluzole has been shown to be an independent prognostic factor in ALS, with fast-progressing patients benefiting the most from treatment 6.
• Other factors, such as age, sex, and site of onset, can also affect survival and prognosis 6.

Safety and Tolerability of Riluzole

• Riluzole is generally well-tolerated, but it can cause adverse events such as asthenia, nausea, and elevated liver enzymes 5.
• Strict monitoring of liver enzymes is recommended for patients taking riluzole, and treatment is contraindicated in patients with elevated transaminases before the start of treatment 5.
