Takeaway
This registry study found that 27.7% of aquaporin-4-antibody (AQP4-ab)-negative Argentinian individuals with neuromyelitis optica spectrum disorder (NMOSD) tested positive for myelin oligodendrocyte glycoprotein antibodies (MOG-ab), in line with results from other world regions.
Why this matters
This is the first Argentinian NMOSD registry to study the percentage of patients in Latin America who have MOG-ab associated disease (MOGAD) and are AQP4-ab-neagtive.
