Predictors of primary progressive multiple sclerosis (PPMS) progression over 10 years include male sex, shorter disease duration, and slower baseline timed walk test. Deterioration in disability and brain volume also predicted long-term outcomes.

Area of Science:

  • Neurology
  • Neuroimmunology
  • Clinical Neuroscience

Background:

  • Primary progressive multiple sclerosis (PPMS) exhibits variable rates of disease progression.
  • Identifying reliable predictors of long-term disability is crucial for patient management and therapeutic development.

Purpose of the Study:

  • To identify predictors of clinical progression in primary progressive multiple sclerosis over a 10-year period.
  • To analyze baseline and 2-year clinical and imaging data to forecast long-term disability.

Main Methods:

  • A multicenter study involving 101 patients with PPMS.
  • Baseline and 2-year imaging and clinical data were collected.
  • Ordinal logistic regression analysis was used to identify predictors of 10-year Expanded Disability Status Scale (EDSS) scores.

Main Results:

  • Male sex, shorter disease duration, and slower baseline timed walk test performance were significant predictors of progression.
  • Worsening EDSS scores and reduction in brain volume over the initial 2 years also predicted long-term disability.
  • The baseline timed walk test emerged as the most robust predictor of disease progression.

Conclusions:

  • Baseline clinical and demographic factors, along with early disease changes, can predict long-term disability in primary progressive multiple sclerosis.
  • These findings offer valuable insights into the heterogeneous nature of PPMS progression.
  • Understanding these predictors may aid in stratifying patients and developing targeted interventions.
