Early onset multiple sclerosis (MS) predominantly follows a relapsing-remitting course. High relapse rates and early disability progression in pediatric MS suggest considering early disease-modifying therapies.

Area of Science:

  • Neurology
  • Pediatric Neurology
  • Immunology

Background:

  • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
  • Early-onset MS (EOMS), defined as onset before age 16, represents a distinct clinical entity.
  • Understanding the long-term clinical course of EOMS is crucial for effective management.

Purpose of the Study:

  • To evaluate the clinical course of MS in individuals with onset before age 16.
  • To compare the disease progression of EOMS with the general MS population.

Main Methods:

  • Retrospective analysis of 116 patients with EOMS from the University of British Columbia MS Clinic database.
  • Data collected included age at onset, disease course, relapse rates, and disability progression (Expanded Disability Status Scale - EDSS).

  • Comparison with data from the Canadian natural history study for MS clinic attendees.

    • Main Results:

    • The mean age at MS onset was 12.7 years, with a mean observation period of 19.8 years.
    • Most EOMS cases (53.1%) transitioned to secondary progressive MS (SPMS) approximately 23 years after onset.
    • Significant disability (EDSS 3.0) occurred at a mean age of 28.5 years, and EDSS 6.0 at a mean age of 32.3 years, with an annual relapse rate of 0.54.

    Conclusions:

    • EOMS is characterized by a predominantly relapsing-remitting (RR) course initially.
    • High relapse frequency and early onset of permanent disability in EOMS warrant consideration for early intervention with disease-modifying therapies.
    • The findings support previous research on the prevalence and clinical characteristics of EOMS.
