Neuromyelitis optica positive antibodies confer a worse course in relapsing-neuromyelitis optica in Cuba and French West Indies

Abstract

NMO IgG positive antibodies in NMO patients had a lower rate in the Caribbean area - where the population has a predominant African ancestry - than in Caucasian Europeans, suggesting the influence of a possible ethnic factor in the pathogenesis of the disease, but they confer a worse course with more attacks, more disability and MRI lesions.
