BACKGROUND: Neuromyelitis optica spectrum disorders (NMOSD) are autoimmune, inflammatory demyelinating diseases of the central nervous system, which have established variations in prevalence across different ethnicities and genders. The objective of this study was to investigate differences in clinical features among men and women with NMOSD, according to the 2015 diagnostic criteria.
METHODS: A total of 97 patients with NMOSD were recruited from inpatient neurology clinics in this retrospective study. Demographic and clinical data were extracted from the various databases. Data on epidemiology, clinical signs, initial symptoms, and laboratory indices of men and women with NMOSD were compared.
RESULTS: The cohort of this study had a female/male ratio of 5.47:1, with annualized relapse rates of 0.72 in female and 0.56 in male patients. Among female patients, 29.2% and 53.6% initially experienced acute optic neuritis and acute myelitis, respectively, while the prevalence of these symptoms was 46.6% and 53.3% among male patients. A total of 14.6% and 2.4% of female patients had area postrema symptoms and other brainstem signs, respectively on study enrollment. The prevalence of anti-AQP4-autoantibodies and anti-thyroid peroxidase autoantibodies/anti-thyroglobulin autoantibodies (TPO/TG-Ab) was significantly higher among women (77% and 45.7%) than among men (46.1% and 13.3%) (P < 0.05 for both comparisons). A total of 11 women with NMOSD (11.3% of the cohort) also had autoimmune diseases.
CONCLUSIONS: Women with NMOSD have higher morbidity levels than men with this disease and are more likely to have autoimmune diseases and brainstem lesions, especially in the area postrema.
