The Spectrum of Clinical Presentation of Multiple Sclerosis and Neuromyelitis Optica Spectrum Disorder in Young Patients of Our Community

Background Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory, demyelinating syndrome of the central nervous system (CNS) which affects the spinal cord and optic nerves. The aim of our study was to evaluate the clinical appearance of multiple sclerosis and neuromyelitis optica spectrum disease in young children in our community Materials and methods This cross-sectional study was done in the neurology departments of the Combined Military Hospital & Pak Emirates Military Hospital Rawalpindi for six months from April 2020 to September 2020. Eighty people between the ages of 18 and 45 with Guillain-Barre syndrome (GBS), multiple sclerosis (MS), and neuromyelitis optica spectrum disorder participated in this prospective research. The patient's demographic profile includes information such as age, gender, length and kind of sickness, and symptoms. The relationship of socio-demographic factors was assessed with the involvement of more than one organ system at the time of presentation. Results The final study comprised of 80 patients of whom 31 (38.5 percent) were men and 49 (61.25%) were women. Fifty-four (67.5%) patients were diagnosed with multiple sclerosis while 26 (32.5%) had neuromyelitis optica spectrum disorders. Most of the patients presented with sensory symptoms followed by visual disturbances. Twenty-nine (37%) had involvement of more than one system while 51 (63%) had involvement of only one system at the time of presentation. Female gender and having a diagnosis of multiple sclerosis had a statistically significant relationship with involvement of one than one system. Conclusions In individuals with MS and NMO, motor, sensory, and visual symptoms were often observed at the time of presentation. Involvement of one than one system at the time of presentation was fairly common among these patients and females and patients having a diagnosis of multiple sclerosis were more at risk of involvement of more than one system.

Clinical Features of the Patients with Neuromyelitis Optica Spectrum Disorder

Introduction

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory, demyelinating syndrome of the central nervous system (CNS) that predominantly affects the spinal cord and optic nerves. Since it was first described, new information about the pathophysiology gained momentum with the discovery of an antibody against Aquaporin-4, a water channel protein that is predominantly found in the astrocytes. In our study, we evaluated the clinical features of NMOSD and clinically related CNS disorders.

Method

In our study, we recruited patients that were followed by Clinic for Multiple Sclerosis and Myelin Disorders at Istanbul University between 1979 and 2016.

Results

Thirty-five NMOSD, fifteen relapsing inflammatory optic neuropathy (RION) and ten opticospinal multiple sclerosis (OSMS) patients were recruited in our study. Forty-eight patients (%80) were female and twelve (%20) were male. Age, sex, follow-up period, annualized relapse rate, relapses in the first two years and progression index were similar between the groups. Cerebrospinal fluid (CSF) protein levels were higher in the NMOSD group. Concomitant autoimmune disorders were observed in six NMOSD patients and two OSMS patients. One patient with RION had nonspecific white matter lesions without gadolinium enhancement in the brain MRI.

Conclusion

Laboratory and imaging findings suggests that NMOSD is a distinct disorder than RION and OSMS. Further studies are needed to say specific comments about the existence of OSMS.
