Non-invasive ventilation in amyotrophic lateral sclerosis: a 10 year population based study

Area of Science:

• Neurology
• Pulmonology
• Epidemiology

Background:

• Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons.
• Respiratory failure is a major cause of mortality in ALS patients.
• Non-invasive ventilation (NIV) is a key treatment to manage respiratory insufficiency in ALS.

Purpose of the Study:

• To assess the clinical characteristics and outcomes of NIV use in a large, population-based series of ALS patients.
• To identify factors influencing NIV adoption and its impact on survival.
• To evaluate the trends in NIV utilization within an epidemiological context.

Main Methods:

• Utilized data from the Piemonte and Valle d'Aosta Register for ALS, a prospective epidemiological registry.
• Analyzed incident ALS cases from 1995-2004, focusing on patients who received NIV.
• Examined demographic, clinical, and survival data associated with NIV use.

Main Results:

• 20.6% of 1260 ALS patients underwent NIV between 1995-2004.
• Younger males and patients from tertiary ALS centers were more likely to receive NIV.
• NIV use increased over time, primarily in tertiary centers, with a median survival of 289 days post-NIV.

Conclusions:

• NIV is an increasingly adopted treatment for respiratory disturbances in ALS, offering survival benefits, particularly in specialized centers.
• Age, gender, and marital status significantly impact NIV accessibility, indicating potential disparities.
• Equitable access to NIV for all ALS patients with respiratory failure should be promoted by addressing sociocultural barriers.
