AQP4+ NMOSD and MOGAD Phenotypes in Animal or Cell Models

A study evaluated relapse outcomes in AQP4-positive NMOSD and MOGAD using treatment data. It found that females were more common in AQP4+ NMOSD, and those patients showed greater disability at diagnosis compared to MOGAD. Monoclonal antibodies improved relapse-free survival in AQP4+ NMOSD but not in MOGAD. In AQP4+ NMOSD, specific male and onset characteristics affected treatment response with rituximab, while optic neuritis in MOGAD influenced relapse-free status.

Why it matters

These findings enhance understanding of how distinct clinical features affect treatment response in AQP4-positive NMOSD and MOGAD, which can inform approach to these conditions. Identifying predictors of treatment outcomes is crucial for improving patient care.

What this does not prove

The research is limited to AQP4-positive NMOSD and MOGAD, which are different from multiple sclerosis, thus findings may not apply to other MS types. This restricts generalizability of the results.

primary endpointWe leveraged the Italian Multiple Sclerosis and Related Disorders (I-MS&RD) Registry to characterise clinical and treatment features of AQP4-positive NMOSD and MOGAD, identify predictors of rituximab treatment response, and assess relapse outcomes across treatment classes.

findingsRESULTS: Female sex was more common in AQP4+ NMOSD than in MOGAD patients (p < 0.001), whereas paediatric onset was more common in MOGAD (p < 0.001).
