Permanent disability, found in 51% of patients with NMOSD at follow-up, was attributed mainly to age of disease onset, delay in diagnosis, and initial EDSS score.

A cross-sectional study showed that retinal measurements in patients with “potential” neuromyelitis optica spectrum disorder were similar to those with definite neuromyelitis optica spectrum disorder.

A report on two patients with late-onset neutropenia resulted in an uncommon adverse event following anti-CD20 therapies.

P100 amplitude of 15 minute checks in the NMOSD-ON group had a significant reduction at 6 months relative to the IDON group, suggesting more several axonal damage.

Annualized relapse rates were elevated compared with the prepregnancy period, especially during the initial 3 months after delivery, whereas EDSS scores worsened during pregnancy and the postpartum period.

A study using patient data from John Hopkins showed that rituximab treatment was associated with reduced annualized relapse rates in AQP4-IgG seropositive NMOSD and MOGAD.

Using magnetic resonance spectroscopy, investigators observed significantly different levels of total NAA across MS and NMOSD subtypes, and a negative correlation between total NAA and disability score.

Among a cohort of more than 300 patients in China, those with APQ4 positive NMOSD reported a significantly lower risk of relapse among those treated with rituximab compared with the other groups.

The founder and executive director of the Sumaira Foundation offered her perspective on the patient journey in NMOSD and the vital need to increase awareness [WATCH TIME: 9 minutes]

CXCL2 and CXCL12, known to induce B-cell proliferation and differentiation, were significantly higher in those with acute and remitted cases of NMOSD compared with controls.

Data assessing samples of deep cervical lymph node aspirates and blood suggest that germinal center activity was associated with clinical relapses in individuals with neuromyelitis optica spectrum disorder.

Data suggest that long-term treatment with immunosuppression therapies, such as rituximab, is generally appropriate for patients with neuromyelitis optica, though transverse myelitis might indicate a higher risk of relapse post discontinuation.

BPCLI was observed in both NMOSD and MOGAD but was relatively rarer in AQP4 NMOSD, with meningoencephalitis-like episodes among the sources of misdiagnosis.

In a cohort of patients with NMOSD, more severe depressive symptoms were associated with increased time-varying functional connectivity between the precuneus and temporal cortex.

Using rigorous cell-based assays, cerebrospinal fluid GFAP levels were significantly lower in double-seronegative NMOSD than AQP4-positive NMOSD but did not differ between those with MOGAD or other neurological diseases.

The director of the Mayo Clinic Center for Multiple Sclerosis and Autoimmune Neurology discussed the technological capabilities the center has, including the improved use of neural antibody testing. [WATCH TIME: 6 minutes]

Neuropathic pain and constipation coexisted in 43.5% of the survey participants, and approximately one-third of patients with both symptoms reported a possible link between the two.

Between AQP4-IgG-positive and negative patients with NMOSD, there were no significant differences in cognitive performance, despite having similar demographic and clinical characteristics.

All 12 of the children met diagnostic criteria for multiple sclerosis and were seropositive for MOG-IgG at baseline experienced a disease course different than typical MS through the observed time.

The director of the Mayo Clinic Center for Multiple Sclerosis and Autoimmune Neurology discussed the complexities in diagnosing autoimmune encephalitis and the approach needed to be taken. [WATCH TIME: 5 minutes]

Through dedicated research into biomarker discovery and patient care, the neuroimmunology laboratory at Mayo Clinic has paved a new way of life for those with autoimmune disorders.

Findings from a new post hoc analysis of data from the randomized-controlled period of the N-MOmentum phase 2/3 pivotal trial (NCT02200770), suggest the Horizon agent is effective in NMOSD.

An expert neurologist, advocacy director, and a pair of patients with NMOSD discuss the current landscape of the demyelinating disorder.

These findings have clinical implications for the diagnosis of AQP4-NMOSD and in helping clinicians differentiating it from other demyelinating diseases such as MOGAD.
