Immunosuppressive therapy significantly reduces relapses in elderly people with late-onset neuromyelitis optica spectrum disorder (NMOSD), with more than half of patients becoming relapse-free, a retrospective study in South Korea has found. Treatment also eased or stabilized disability for most patients, without a marked risk of severe infections, and was…

Treatment with rituximab significantly reduces the risk of relapse and lessens disability in neuromyelitis optica spectrum disorder (NMOSD) patients with antibodies against aquaporin-4 (AQP4), according to a long-term, retrospective Australian study. Most of the analyzed patients received an initial infusion of rituximab at 1,000 mg, given as two separate…

Enspryng (satralizumab-mwge) promotes an anti-inflammatory profile in plasmablasts, the immune cells that produce large amounts of the self-reactive antibodies that drive most cases of neuromyelitis optica spectrum disorder (NMOSD). That’s according to a study analyzing immune cells from NMOSD patients before and after treatment with Enspryng, as well…

The circulating levels in the blood of six inflammatory proteins may help predict the risk of relapse and severe attacks in people with neuromyelitis optica spectrum disorder (NMOSD), a study from China reports. Four of these inflammation-related proteins — FGF-23, DNER, GDNF, and SLAMF1 — were used to build…

Long-term treatment with Uplizna (inebilizumab) was well tolerated and led to sustained disease control for adults with neuromyelitis optica spectrum disorder (NMOSD). That’s according to final data from the open-label extension period of the Phase 2/3 N-MOmentum clinical trial (NCT02200770), top-line data of which supported the therapy’s…

People having area postrema syndrome (APS), that is, uncontrollable nausea, vomiting, or hiccups, as the first symptom of neuromyelitis optica spectrum disorder (NMOSD) are more likely to relapse sooner and more frequently than those having another first symptom. These are the main findings of a single-center study that retrospectively…

Higher levels of self-reactive antibodies against aquaporin-4 protein (AQP4), which drives neuroinflammation in most cases of neuromyelitis optica spectrum disorder (NMOSD), correlate with more severe relapses and visual disability, according to a large study. Even after treatment with immunosuppressive agents, patients with high anti-AQP4 antibodies experienced more severe relapses.

Women with elevated blood levels of the sex hormone progesterone have an increased risk of developing neuromyelitis optica spectrum disorder (NMOSD), according to a study that analyzed genetic variants associated with sex hormone levels. In a reverse analysis, having NMOSD appeared to lower testosterone and increase the sex hormone-binding…

People with neuromyelitis optica spectrum disorder (NMOSD) have significantly lower vitamin D levels in their blood than do healthy individuals, according to a meta-analysis of data from studies covering more than 900 people in Asia. While the findings don’t prove that vitamin D deficiency causes NMOSD, they call attention…

Immune T-cells of the CAR T-cell therapy CT103A are able to rapidly eliminate disease-driving immune cells and reduce immune cells’ overall inflammatory activity in people with neuromyelitis optica spectrum disorder (NMOSD), a study shows. “This study is the first in-depth single-cell … analysis of multiple types of body fluids…
