Summary

Devic's neuromyelitis optica (DNMO) is a severe neurological disease distinct from multiple sclerosis (MS). Careful diagnostic criteria are crucial for differentiating DNMO, which has a poor prognosis and limited treatment options.

Area of Science:

  • Neurology
  • Immunology
  • Pathology

Background:

  • Multiple sclerosis (MS) is a common demyelinating disease of the central nervous system.
  • Devic's neuromyelitis optica (DNMO) is a distinct neurological disorder affecting the optic nerves and spinal cord, characterized by necrosis and atrophy.
  • DNMO has a poor prognosis and lacks established effective treatments.

Purpose of the Study:

  • To delineate the clinical, biological, pathological, and radiological features of DNMO.
  • To establish clear criteria for differentiating DNMO from MS.
  • To evaluate treatment outcomes in DNMO patients.

Main Methods:

  • Retrospective analysis of 14 patients diagnosed with possible DNMO across three French hospitals (1980-1999).
  • Literature review to supplement patient data.

  • Application of strict inclusion and exclusion criteria for DNMO diagnosis.

    • Main Results:

    • Nine patients met the criteria for definite DNMO; five were excluded.
    • DNMO presentation varied (monophasic or multiphasic) with a generally poor prognosis.
    • Severe outcomes included death (2/9) and significant disability (5/9); immunosuppressive treatments showed limited efficacy.

    Conclusions:

    • Few reported cases meet definitive DNMO criteria; many are misdiagnosed MS or other white matter diseases.
    • Cerebrospinal fluid analysis and neuroimaging are vital for DNMO diagnosis.
    • Adherence to specific diagnostic criteria is essential for distinguishing DNMO from MS and other central nervous system white matter diseases.
