New progress in the treatment of neuromyelitis optica spectrum disorder with monoclonal antibodies (Review)

Neuromyelitis optica spectrum disorder (NMOSD) is a group of immune-mediated inflammatory demyelinating diseases mainly affecting the central nervous system. It is characterized by high risk of relapse and progression to disability. The frequent recurrences of neuromyelitis optica spectrum disorder often exacerbate the neurological dysfunction and severely affect the patient's quality of life. Conventional treatments for neuromyelitis optica spectrum disorder, including acute treatment and sequential therapy, aim to decrease the degree of disability and recurrences. In recent years, new monoclonal antibodies have yielded encouraging results. The present review discusses the research status and recent progress in the treatment of NMOSD with monoclonal antibodies.
