Understanding Lupus Myelitis and its Etiology
Lupus myelitis is a term that can create confusion, as it suggests a direct link between lupus and myelitis. However, recent research indicates that a significant number of patients with rheumatologic diseases, such as lupus, may actually have aquaporin-4 IgG seropositive neuromyelitis optica spectrum disorder (NMOSD). In a study, nearly half of the patients diagnosed with inflammatory myelopathy were found to have this condition, highlighting the importance of recognizing it not merely as a manifestation of lupus but as a coexisting autoimmune disorder. This distinction is crucial in clinical practice to prevent misdiagnosis and ensure accurate treatment approaches.
