People with neuromyelitis optica spectrum disorder (NMOSD) who test positive for self-reactive antibodies against the aquaporin 4 (AQP4) protein are more likely to be women, and have an earlier disease onset and more relapses than those who test negative. That’s according a single-center study in Argentina that also showed…

A predictive model based on laboratory and clinical risk factors for relapses in neuromyelitis optica spectrum disorder (NMOSD) was found to accurately discriminate NMOSD patients experiencing a relapse within one year of diagnosis from those without a relapse, a study showed. The identified risk factors were numbers and ratios…

Biologic immunosuppressants are more effective than conventional immunosuppressants for people with neuromyelitis optica spectrum disorder (NMSOD) with self-reactive antibodies against the AQP4 protein. That’s according to real-world data from a Japanese study comparing biologic therapies — Soliris (eculizumab), Enspryng (satralizumab), Ultomiris (ravulizumab), Uplizna (inebilizumab), and…

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…

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…

Uplizna (inebilizumab) treatment markedly reduces the number of several subsets of immune B-cells that are linked to disease relapses in people with neuromyelitis optica spectrum disorder (NMOSD), trial data show. The therapy also lowers levels of the self-reactive antibodies against the AQP4 protein that drive most NMOSD cases,…

None of the neuromyelitis optica spectrum disorder (NMOSD) patients in the Phase 3 CHAMPION-NMOSD clinical trial have had a disease relapse while on Ultomiris (ravulizumab-cwvz) treatment for a median of more than 2.5 years. These findings were shared by Sean Pittock, MD, the trial’s principal investigator, at the…

Tocilizumab, an anti-inflammatory medication used off-label for neuromyelitis optica spectrum disorder (NMOSD), can help prevent relapses (flare-ups) and ease disability while being generally safe, according to a meta-analysis. The study, “Tocilizumab treatment in neuromyelitis optica spectrum disorders: Updated meta-analysis of efficacy and safety,” was published in the journal…

Nearly two in 10 neuromyelitis optica spectrum disorder (NMOSD) patients develop new asymptomatic brain and spinal cord lesions during the period of disease remission, but these do not appear to increase risk of relapse, according to a study in Argentina. Asymptomatic, or silent, lesions are those that can be…

The presence of certain self-reactive antibodies called antinuclear antibodies (ANAs) in the blood is associated with worse disability and more severe relapses in people with neuromyelitis optica spectrum disorder (NMOSD), according to a study from China. “Our results suggest that ANA seems to be more associated with severe disease…
