People with neuromyelitis optica spectrum disorder (NMOSD) who test positive for NMOSD-driving self-reactive antibodies against the AQP4 protein and Black patients are significantly more likely to have worse disability related to vision. These are the findings of a North American study that analyzed patient data with NMOSD-specific disability scales…

Early use of immunosuppressive therapy — when compared with a later treatment start — was associated with fewer relapses and reduced disability among neuromyelitis optica spectrum disorder (NMOSD) patients with self-reactive antibodies against the AQP4 protein, a study from China showed. The data demonstrated a time-dependent treatment efficacy, with…

Children with neuromyelitis optica spectrum disorder (NMOSD) who live in disadvantaged socioeconomic neighborhoods are more likely to have more severe disease-related disabilities, a study in the U.S. indicates. Two years after a diagnosis, Black pediatric patients had significantly more severe disability, as assessed with the standard Expanded Disability Status…

The composition of bacteria in the gut is altered in neuromyelitis optica spectrum disorder (NMOSD) patients experiencing disease relapses compared with healthy people in the same household, a study reports. Following treatment, however, the gut bacterial profiles of NMOSD patients in remission resembled those of healthy people. “The…

People with neuromyelitis optica spectrum disorder (NMOSD) often have other co-occurring autoimmune diseases and those who do have a significantly higher risk of a relapse than people with NMOSD alone, a study in Portugal suggests. Long-term disability outcomes didn’t differ between the two groups, however, suggesting “appropriate treatment may…

Testing for the self-reactive antibodies that drive most cases of neuromyelitis optica spectrum disorder (NMOSD) in dried blood spots (DBS) is as accurate as testing blood samples, a study shows. The findings suggest the dried blood spot technique could be a viable alternative to conventional blood sample testing for…

A seaweed-derived preparation named GV-971 (sodium oligomannate) that has anti-inflammatory effects through the gut-brain axis, delayed the onset and progression of neuromyelitis optica spectrum disorder (NMOSD) in mouse models of the disease, a study shows. The preparation developed by Green Valley Pharmaceuticals is approved in China as an…

About half of neuromyelitis optica spectrum disorder (NMOSD) patients who test positive for self-reactive antibodies, or autoantibodies, against the AQP4 protein — a hallmark of the autoimmune disease — have at least one other type of autoantibody, according to a new study from South Korea. Many of these other…

HNSA-5487, Hansa Biopharma’s experimental treatment for neuromyelitis optica spectrum disorder (NMOSD) and other autoimmune diseases, safely and effectively reduced the levels of immunoglobulin G (IgG) antibodies — ones involved in the abnormal immune attacks that drive these conditions — in a Phase 1 clinical trial involving healthy volunteers.

In the five years before their first disease attack, people with neuromyelitis optica spectrum disorder (NMOSD) required significantly more doctor’s office visits and hospitalizations than their peers in the general population, a new study from Canada found. The researchers believe these findings point to the presence of an NMOSD…
