Brief Summary

Neuromyelitis Optica Spectrum Disorders (NMOSD) are a group of inflammatory demyelinating disorders of the central nervous system. Although NMOSD occurs much more commonly in nations with a predominately non-Caucasian population, NMOSD are underestimated in Egypt and frequently misdiagnosed as multiple sclerosis (MS). In this study, by investigating serum anti-aquaporin (AQP) 4 and anti-MOG antibody of patients suspected to have NMOSD attending the Neurology and Psychiatry department of Assiut University Hospital, investigators aim to determine the relative frequency, clinical and radiological characteristics of NMOSD in upper Egypt community and compare it with other populations of different races.

Outcome Measures

Primary Outcomes (1)

  • the percentage of increase in NMOSD diagnostic rates by screening for serum anti-AQP4 and anti-MOG antibodies

    To assess the role of screening for Serum anti-AQP4 and anti-MOG antibodies in patients with idiopathic inflammatory central nervous system demyelinating disorders on diagnostic rates of NMOSD

    one year period

Secondary Outcomes (2)

  • percentage of patients were misdiagnosed as MS after screening for serum anti-AQP4 and anti-MOG antibodies

    one year period

  • the percentage of increase of anti-MOG associated diseases after screening for serum anti-MOG antibodies

    one year period

Interventions

All patients suspected to have NMOSD according to the recent diagnostic criteria will be examined for serum aquaporin 4 antibody (AQP-4-Ab) and serum myelin oligodendrocyte glycoprotein antibody (anti-MOG)

All patients suspected to have NMOSD according to the recent diagnostic criteria will be examined for serum myelin oligodendrocyte glycoprotein antibody (anti-MOG) if they tested negative for serum aquaporin 4 antibody (AQP-4-Ab)

All patients suspected to have NMOSD according to the recent diagnostic criteria will have MRI brain, spine and orbit with Gadolinium

You may qualify if:

  • All cases that fulfill the international 2015 consensus criteria of NMOSD
  • Any episode suggestive of idiopathic inflammatory demyelinating central nervous system disease including
  • longitudinally extensive transverse myelitis (LETM) or optic neuritis (ON) plus Cerebral or Brainstem syndrome (LETM or ON PLUS)
  • optic neuritis (ON)
  • longitudinally extensive transverse myelitis (LETM),
  • Transverse myelitis with non-extensive lesion (NETM)
  • Acute encephalomyelitis (ADEM).
  • Atypical MS cases (atypical clinical presentation, course, radiological findings or atypical response to treatment)
  • Age: all patients of both sexes and all age groups will be included.

You may not qualify if:

  • An alternate diagnosis became apparent
  • if no serum sample was supplied
  • Subject declined to provide written informed consent.
