Neuromyelitis optica spectrum disorder co-existing with antiphospholipid syndrome: A case report.
Clinical Case Reports 2024 May
KEY CLINICAL MESSAGE: Neuromyelitis optica spectrum disorder is an autoimmune disease, rarely presents with antiphospholipid syndrome. Diagnosis and management of NMOSD are challenging in the background of diverse presentations, especially in resource-limited settings.
ABSTRACT: Neuromyelitis optica spectrum disorder (NMOSD) is a progressive demyelinating autoimmune condition resulting from the autoantibodies produced against aquaporin-4 (AQP-4) proteins which are widely distributed in astrocytes in the nervous system. In the setting of NMOSD, it is very crucial to consider other autoimmune diseases as differential diagnoses or co-occurrences due to the diversity of symptoms. NMOSD co-exists with other autoimmune diseases such as myasthenia gravis, thyroid disease, ankylosing spondylitis, pernicious anemia, thrombotic thrombocytopenic purpura, ulcerative colitis, and systemic lupus erythematosus. Few cases of antiphospholipid syndrome co-existing with NMOSD have been reported. In resource-limited settings, the published data are scarce, and therefore, autoimmune diseases are poorly studied. Therefore, late diagnosis and delayed treatment initiation pose long-term sequelae and hence poor prognosis. Here, we present a case of an African woman in her early 40s presenting with bilateral progressive loss of vision, transverse myelitis, extensive longitudinal hyperintense T2 cervical lesion, and AQP-4 autoantibody keeping with NMOSD. The co-existence of antiphospholipid syndrome, in this case, was supported by a history of recurrent pregnancy loss and positive antiphospholipid antibodies. This case underscores the importance of individualized-based medicine, especially in resource-limited settings.
