This study is a multicenter, prospective cohort study designed to enroll 50 NMOSD patients who receive Satralizumab treatment during the early phase of an NMOSD attack. Follow-up visits will be conducted at baseline, 3 months, and 6 months to record and assess EDSS scores, modified Rankin Scale (mRS) scores, EQ-5D scores, Activities of Daily Living (ADL) scores, relapse events, safety data, and exploratory endpoints (e.g., blood inflammatory markers and visual function), with the aim of evaluating the efficacy and safety of Satralizumab in the early treatment of NMOSD-thereby providing patients with more effective therapeutic options and further optimizing the clinical management of NMOSD.
Patients with NMOSD (AQP4-IgG-positive) at early phase of an NMOSD attack, and age ≥ 18 years. The EDSS score ≤ 8.5 during an acute relapse in NMOSD.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
