Understanding the characteristics of neuromyelitis optica spectrum disorder (NMOSD) with recurrent short partial transverse myelitis (SPTM), which is very rare, contributes to the differential diagnosis of multiple sclerosis (MS). We present two Chinese aquaporin-4 immunoglobulin G (AQP4-IgG)-seropositive NMOSD cases who had at least twice SPTM during 4 and 6 years of follow-up, respectively. Their SPTMs have been mild and responded well to corticosteroids just like in the case of MS. The findings highlight the need of searching for serum AQP4-IgG (cell-based assay strongly recommended) in patients with recurrent SPTM and suggest that those patients may have a mild acute attack phase and favorable long-term prognosis.

Neuromyelitis optica (NMO), mainly affecting optic nerve and spinal cord, can also manifest diverse ocular symptoms due to brain abnormalities. We present a cortical oscillopsia without nystagmus or head tremor in a patient with neuromyelitis optica spectrum disorder (NMOSD) with anti-aquaporin 4 antibody. This rare ocular manifestation, which is easily underestimated owing to absence of the typical nystagmus, can be an initial manifestation of NMOSD.

Background and objective: The objective of this study is to clarify clinical, immunological, and neuroimaging features in anti-aquaporin-4 (AQP4) antibody-positive and antibody-negative Sjögren’s syndrome (SS) patients with central nervous system (CNS) involvement. Methods: Medical records and MRI scans were retrospectively analyzed in 22 consecutive SS patients with CNS manifestations. Results: Seven (31.8%) patients were positive for anti-AQP4 antibodies. The frequency of visual impairment was higher in anti-AQP4 antibody-positive patients than in antibody-negative patients (71.4% vs. 0.0%, p = 0.0008). Brain MRI showed that discrete lesions were more commonly found in the cerebrum, brainstem, and optic nerve in anti-AQP4 antibody-positive patients than in antibody-negative patients ( p = 0.002, p = 0.006, and p = 0.004, respectively), while spinal cord MRI showed that posterior column lesions in the cervical spinal cord were more frequent in anti-AQP4 antibody-positive patients than in antibody-negative patients (71.4% vs. 14.3%, p = 0.01). SS-A antibody titers were higher in anti-AQP4 antibody-positive patients than in antibody-negative patients ( p = 0.012) and were also higher in patients with longitudinally extensive spinal cord lesions (LESCLs) than in those without LESCLs ( p = 0.019). Conclusions: In SS, the presence of anti-AQP4 antibodies is associated with involvement of the optic nerve, cerebrum and brainstem, and with cervical posterior column lesions in the spinal cord.

Background: The absence of Aquaporin-4 Antibody (AQP4-Ab) in a fraction of the Neuromyelitis Optica Spectrum Disorder (NMOSD) patients has led to a search for other serologic markers. Myelin Oligodendrocyte Glycoprotein (MOG) is a protein component of the myelin sheets encapsulating the neural fibers. Objectives: We aimed to compare the presence and levels of anti-MOG (Ig-G) in a group of seronegative NMOSD patients with a healthy control group. Materials & Methods: In this cross-sectional study, 30 NMOSD patients with negative AQP-Ab status, who were referred to the Neurology Clinic of Kashani University Hospital in Isfahan City, Iran, from March 2015 to March 2016, and 26 healthy controls were consecutively recruited. Their baseline demographic and clinical data were recorded. Serum anti-MOG levels were measured in both groups. The obtained data were analyzed using the Student t-test, Mann-Whitney U, and Chisquare test in SPSS V. 18. Results: The anti-MOG test results were statistically higher in patients (n=12, 37.5%) compared to controls (n=0, 0%) (P<0.0001). The level of anti-MOG in Healthy Control (HC) was higher compared to patients with negative anti-MOG (P<0.0001) and was lower than patients with positive anti-MOG (P<0.0001). Conclusion: Our study showed that nearly one-third of seronegative NMOSD patients were positive for MOG-Ab. Further studies are needed to assess the characteristics and outcome of these patients.
