[Comorbidity of neuromyelitis optica spectrum disorder and systemic lupus erythematosus].
The comorbidity of neuromyelitis optica spectrum disorder (NMOSD) and systemic lupus erythematosus (SLE) is a poorly studied problem. The issues of the pathogenetic relationship between these diseases, timely diagnosis of their co-existence in one patient, disease course and therapeutic approaches are the most relevant. The authors summarize current views on the state of the problem and analyze three clinical cases of NMOSD and SLE comorbidity including the diagnostic issues and therapeutic approaches.
