People with a genetic makeup that causes them to be more susceptible to COVID-19 are nearly five times as likely to develop neuromyelitis optica spectrum disorder (NMOSD) associated with antibodies against aquaporin-4 (AQP4), a study finds. Evidence for a cause and effect, or causal, link between COVID-19 and NMOSD…

The U.S. Food and Drug Administration (FDA) has asked for modifications to the risk evaluation and mitigation strategy — known as REMS — for Ultomiris (ravulizumab) before approving the therapy for most adults with neuromyelitis optica spectrum disorder (NMOSD). Ultomiris already is available in the U.S. for treating…

Neuromyelitis optica spectrum disorder (NMOSD) is associated with a faster loss of white matter volume in the brain, but taking the corticosteroid prednisolone may help counter this effect, according to a small study in Japan. The brain’s white matter contains the long, wire-like projections, or fibers, that nerves use…

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…

Neuromyelitis optica spectrum disorder (NMOSD) patients have significantly poorer nutritional status than healthy people which is associated with worse quality of life, a study found. Longer disease duration; poor sleep quality; being a woman; and higher levels of anxiety, depression, or fatigue were found to be significantly associated with…

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…

Long-term use of the approved therapy Soliris (eculizumab) safely and effectively prevents relapses in the real world in people with neuromyelitis optica spectrum disorder (NMOSD) and antibodies against the AQP4 protein. That’s according to two-year interim data from an observational study in Japan, where Soliris was approved in…

The presence of lesions in the brain’s middle medulla, a control center for breathing, increases the likelihood of acute respiratory failure in people with neuromyelitis optica spectrum disorder (NMOSD), a study suggests. While middle medullary lesions on MRI were the key predictor of acute respiratory failure in patients with…

Having optic neuritis — inflammation of the nerves that relay information between the eyes and the brain — as a first symptom of neuromyelitis optica spectrum disorder (NMOSD) is one of the factors that predict visual disability in up to five years, according to a study in China. Other…

Achieving nine goals could help address inequities with access to properly diagnosing and treating neuromyelitis optica spectrum disorder (NMOSD), a Massachusetts physician maintains. The goals were proposed by Farrah Mateen, MD, PhD, of the Massachusetts General Hospital, Boston as a personal viewpoint in the Multiple Sclerosis Journal under…
