Percutaneous endoscopic gastrostomy (PEG) in patients with ALS and bulbar dysfunction

Area of Science:

• Neurology
• Gastroenterology
• Clinical Nutrition

Background:

• Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons.
• Nutritional status is a critical factor in ALS progression and patient management.
• Percutaneous endoscopic gastrostomy (PEG) is a common intervention for nutritional support in ALS.

Purpose of the Study:

• To compare the characteristics of ALS patients who underwent percutaneous endoscopic gastrostomy (PEG) with those who did not.
• To evaluate the timing of PEG placement in relation to disease progression and patient outcomes.
• To assess the impact of PEG on resource utilization and health status in ALS patients.

Main Methods:

• Analysis of data from the ALS Patient Care Database for patients with and without PEG.
• Inclusion criteria focused on patients with ALS Functional Rating Scale-bulbar subscale (ALSFRSb) scores less than or equal to 5.
• Collection and analysis of follow-up data to assess PEG impact and survival.

Main Results:

• PEG use increased significantly with declining ALSFRSb scores, indicating late initiation.
• PEG patients exhibited lower ALSFRS composite, bulbar, and arm subscale scores, used more assistive devices and healthcare resources, and reported lower health status.
• No survival benefit was observed with PEG use; positive impact was noted more frequently when PEG was initiated earlier.

Conclusions:

• PEG is often performed late in ALS progression, potentially after severe bulbar dysfunction and significant disease advancement.
• The timing of PEG placement may be too late to demonstrate survival benefits, highlighting the need for earlier intervention.
• Aggressive and proactive nutritional management, including earlier consideration of PEG, is essential for improving outcomes in ALS patients.
