Smoking is associated with a significantly higher risk of residual disability from onset attack in neuromyelitis optica spectrum disorder (NMOSD) patients with antibodies against the AQP4 protein, a new study showed. Similar results were seen for the presence of nonsmoking vascular risk factors (VRF) such as high blood pressure,…

The platelet-to-lymphocyte ratio, a blood inflammatory marker that can be calculated based on the results of a simple blood test, may be used as a biomarker of disability severity in people with neuromyelitis optica spectrum disorder (NMOSD), a small study showed. Researchers identified four other ratios, calculated based on…

Starting off-label treatment with tocilizumab after the first disease attack in neuromyelitis optica spectrum disorder (NMOSD) is more effective at reducing disability than switching to tocilizumab after other therapies fail to control the disease, a study shows. Still, the risk of relapse over three years remained the same regardless…

Regular maintenance treatment with low-dose rituximab is associated with less disability and fewer relapses among people with neuromyelitis optica spectrum disorder (NMOSD) compared with receiving irregular doses of the preventive therapy, according to a two-year real-world study in China. “Regular [rituximab] treatment can significantly reduce the annual relapse rate, incidence…

Blood levels of markers of brain cell damage may be used to distinguish between attack and remission periods in neuromyelitis optica spectrum disorder (NMOSD) patients, but analysis of these blood biomarkers should be done at specific times to get the best accuracy. Those are the findings from a study…

Switching from Soliris (eculizumab) to Enspryng (satralizumab) is a safe and effective approach for neuromyelitis optica spectrum disorder (NMOSD) patients testing positive for antibodies against the AQP4 protein. That’s according to data from five patients in the U.S. who switched treatments due to either preference for route…

Initiatives are underway worldwide to mark NMOSD Awareness Month, with the goal of boosting awareness of neuromyelitis optica spectrum disorder (NMOSD/NMO) and spotlight people who live with the rare neurological disease. March has been recognized as NMOSD Awareness Month since 2016 in the U.S. and elsewhere. Leading the charge…

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…

People with neuromyelitis optica spectrum disorder (NMOSD) have significantly higher levels of the signaling molecule CXCL13 in their blood and cerebrospinal fluid (CSF), the liquid surrounding the brain and spinal cord, a study shows. Also, CXCL13 levels were significantly associated with disability, with higher levels being detected in NMOSD…
