Title: Subacute Blindness Revealing an Autoimmune Glial Fibrillary Acidic Protein Astrocytopathy. Author: Mabrouki FZ, Aziouaz F, Sekhsoukh R, Yassine M. Journal: Cureus; 2021 Aug; 13(8):e17588. PubMed ID: 34646641. Abstract: Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is an autoimmune disease of the central nervous system characterized by positive GFAP autoantibody. The most common are encephalitis, meningoencephalitis or meningoencephalomyelitis. Antibodies in cerebrospinal fluid (CSF) against GFAP are biomarkers and expressed in most cases with autoimmune GFAP astrocytopathy. Diagnosis by biopsy is not common practice and has been rarely performed in the literature. This is the particularity of our reported case of autoimmune GFAP astrocytopathy presented as opticopyramidal syndrome, all paraclinical investigations were normal, only the biopsy allowed the diagnosis.[Abstract] [Full Text] [Related] [New Search]
