The patient was a 71-year-old woman with aquaporin-4-antibody positive neuromyelitis optica (NMO), with no history of diabetes. On admission, although she showed an extremely elevated plasma glucose level (1,080 mg/dL), her hemoglobin A1c level was low (7.1%), which indicated the rapid progression of diabetes. She also showed ketoacidosis and had a human leukocyte antigen haplotype, DRB1*09:01-DQB1*03:03 associated with Fulminant type 1 diabetes (FT1D). Based on these results, the patient was diagnosed with FT1D. We herein describe the first reported case of a patient with FT1D with NMO, which raises the possibility that T-cell-mediated autoimmunity is involved in the pathogenesis of both FT1D and NMO.
