Abstract:
Objective To explore the clinical features of late-onset neuromyelitis optica spectrum disorders (LON?MOSD). Methods A retrospective analysis was performed to evaluate 61 patients with LONMOSD admitted to our hospital from January 2010 to May 2015. Results (1) The median age at onset was 57 (53, 63) years, male/female was 1∶3.7. Thirty-two patients (52.5%) had transverse myelitis (TM) and 16 patients (26.2%) had optic neuritis (ON) at the disease onset. Fifty-one patients (83.6%) experienced recurrent attacks. Forty patients (65.6%) showed abnormal brain magnetic resonance imag?ing (MRI). Spinal cord MRI showed more frequently present in thoracic regions (39.3%). (2) There were no significant differ?ences in clinical features between AQP-4 seropositive and seronegative groups. (3) By Spearman analysis, it was obvious that EDSS scores at acute phase and remission were positively correlated to AQP-4 antibody levels (rs=0.389, P<0.01;rs=0.380, P<0.01). But there was no correlation between the mean segments of spinal cord and relapse rates with AQP-4 anti?body levels (rs=0.146, P>0.05;rs=0.096, P>0.05). Conclusion LONMOSD patients are more prone to present with TM at onset and have more lesions in thoracic spinal cord and brain. The AQP-4 antibody titres can indicate the severity of disease in acute phase.
