Different patterns of shrinkage in the brain and spinal cord are associated with distinct clinical outcomes in people with neuromyelitis optica spectrum disorder (NMOSD), a study reports. Findings suggest that NMOSD patients showing shrinkage, or atrophy, in outer brain regions are more likely to experience substantial physical disability and/or…
People with neuromyelitis optica spectrum disorder (NMOSD) have abnormally high levels of S100A9, a protein that drives the inflammatory activity of certain immune cells, a study discovered. According to the researchers, higher S100A9 levels in the blood were significantly associated with more severe disability among patients. These findings thus…
High levels of two proteins, called FAM3B and PF4V1, are associated with a reduced risk of neuromyelitis optica spectrum disorder (NMOSD), while elevated levels of two other proteins, called CLEC11A and SERPINA1, are linked to increased odds of developing the immune system disease. These are the findings of a…
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…
Shingles is caused by an infection of the varicella-zoster virus (VZV), but in rare cases, it may trigger neuromyelitis optica spectrum disorder (NMOSD), a new study reports. The study’s researchers said clinicians should look for possible signs of NMOSD in patients being treated for shingles, even though developing NMOSD…
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…
Neuromyelitis optica spectrum disorder (NMOSD) patients whose first symptoms affect the brainstem, which is the bottommost part of the brain, are frequently misdiagnosed and experience higher rates of relapses, according to a two-center study in China. Data also showed about half of these patients initially experienced uncontrollable nausea, vomiting,…
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…
The risk of developing type 2 diabetes is more than 50% higher among people with neuromyelitis optica spectrum disorder (NMOSD) compared with matched people without the neurological condition, a study found. Results suggest that the risk of diabetes is particularly high in NMOSD patients who have receive treatment with…
