A 67-year-old woman presented with fever and a cold a week later, with symptoms of hyperglycemia. After 10 days, her non-fasting blood glucose level was 586 mg/dL, and glycosylated hemoglobin (HbA1c) was 7.2%. She then developed diabetic ketosis and was treated with insulin. Her fasting C-peptide immunoreactivity (CPR) became 0.4 ng/mL. However, her insulin requirement was subsequently reduced. After two months, her CPR was 1.07 ng/mL at zero minutes and 2.04 ng/mL at six minutes in a glucagon stimulation test. Daily urinary CPR was 62 mg. Even though fulminant type 1 diabetes was indicated from the clinical course, insulin secretory ability improved.
一名67岁女性一周后出现发热和感冒，并伴有高血糖症状。10天后，她的非空腹血糖水平为586mg/dL，糖化血红蛋白（HbA1c）为7.2%。随后她发展为糖尿病酮症，并接受胰岛素治疗。她的空腹C肽免疫反应性（CPR）降至0.4ng/mL。然而，她随后的胰岛素需求量减少。两个月后，在胰高血糖素刺激试验中，她的CPR在零分钟时为1.07ng/mL，六分钟时为2.04ng/mL。每日尿CPR为62mg。尽管从临床病程来看提示为暴发性1型糖尿病，但胰岛素分泌能力有所改善。
