Factors predicting survival in ALS: a multicenter Italian study

Area of Science:

• Neurology
• Epidemiology
• Clinical Research

Background:

• Amyotrophic Lateral Sclerosis (ALS) prognosis is influenced by various factors.
• Understanding these factors is crucial for patient care and research.

Purpose of the Study:

• To investigate the impact of clinical characteristics and therapeutic interventions on ALS prognosis.
• To identify independent prognostic factors for ALS survival.

Main Methods:

• Retrospective analysis of 2648 ALS patients diagnosed between 2009-2013 across 13 Italian centers.
• Data collection included phenotypic profiles, follow-up data, and diagnostic certainty (revised El Escorial criteria).
• Univariate and multivariate analyses were performed to identify survival predictors.

Main Results:

• Median survival time from onset to death/tracheostomy was 44 months.
• Independent prognostic factors identified include age at onset, diagnostic delay, and phenotype.
• Riluzole use and diagnostic certainty (R-EEC) were also significant predictors.

Conclusions:

• Clinical and demographic factors significantly impact ALS survival.
• Differences observed between referral center patients and the general ALS population warrant further investigation.
• Findings can inform clinical practice, trial design, and prognostic tool development for ALS.
