Milk production hormone prolactin linked to active NMOSD, study finds

Blood levels of prolactin, a hormone mostly known for its role in milk production, are significantly elevated in people with neuromyelitis optica spectrum disorder (NMOSD) as compared with healthy adults, a study found. Among NMOSD patients, these high prolactin levels were significantly associated with active disease, sensory-related symptoms, and…

Soliris now approved in China to treat adults with NMOSD

Soliris (eculizumab) has been approved in China to treat adults with neuromyelitis optica spectrum disorder, known as NMO or NMOSD, who test positive for antibodies against the aquaporin-4 (AQP4) protein. The therapy — which works to reduce the risk of relapse and ease inflammation among patients — was approved…

Genetic analysis links cold sores, shingles to NMOSD

Genetic variations linked with cold sores and shingles infections have been associated with the development of AQP4 antibody-positive neuromyelitis optica spectrum disorder (NMOSD), according to genetic analysis. The findings suggest that the herpes simplex virus, which is the cause of cold sores, and the varicella-zoster virus, which leads to…

Bodily function problems found to impact quality of life in NMOSD

Symptoms related to the autonomic nervous system, which controls automatic bodily function, have a significant impact on the quality of life of people with neuromyelitis optica spectrum disorder (NMOSD), according to a questionnaire-based study. All patients in the study experienced some autonomic system-related symptoms, or autonomic dysfunction, and most…

AIMP1 Protein May Be Promising Biomarker for NMOSD, Study Shows

People with neuromyelitis optica spectrum disorder (NMOSD) have elevated levels of the pro-inflammatory protein AIMP1 in the bloodstream, and higher levels seem to correlate with worse disability, a study showed. These AIMP1 levels dropped markedly after anti-inflammatory therapy, but still remained higher among patients in remission than in people…

Oval-Shaped Masses More Prevalent in Eyes of NMOSD Patients: Study

Adults with neuromyelitis optica spectrum disease (NMOSD) who are positive for antibodies against the aquaporin-4 (AQP4) protein have a higher prevalence of oval-shaped masses surrounding the optic nerve in their eyes than healthy people, a study showed. Although these masses were significantly linked to older age, their occurrence was…

ESR1 Gene Variations More Common in Women With NMOSD: Study

Certain variations in the ESR1 gene — a protein-coding gene for estrogen receptor-alpha — are significantly more common among women with neuromyelitis optica spectrum disorder (NMOSD) or multiple sclerosis (MS) than among healthy women, a small study suggests. Such differences were not observed between men with these…

High Incidence of Pain in NMOSD Is Mostly Nerve-related

The incidence of pain in adults with neuromyelitis optic spectrum disorder (NMOSD) is high and was reported as the first sign of an inflammatory attack in half of patients, according to an examination of medical records. Neuropathic (nerve-related) pain, marked by uncomfortable burning or tingling, was the most common…
