Abstract
Fulminant type 1 diabetes (FT1D) is a rapidly progressive form of diabetes in which the endogenous capacity to secrete insulin is depleted. The onset is unpredictable with conventional FT1D, and a few reports have tracked C-peptide in patients with conventional FT1D pre-onset. In this report, we present two typical cases of conventional FT1D where C-peptide was monitored from the onset of precursor symptoms to the development of diabetic ketoacidosis (DKA). Furthermore, we conducted a literature review and provide a detailed description of the process of C-peptide depletion in conventional FT1D. Case 1 involved a 72-year-old woman who initially presented with fever and fatigue. Case 2 involved a 45-year-old woman with fever, abdominal pain, and acute pancreatitis. In both cases, DKA developed five days after initial symptoms. A noteworthy observation in both cases was the drastic drop in C-peptide, which was detectable at initial presentation but depleted by the time of DKA diagnosis. These cases emphasize the importance of close follow-up of plasma glucose and serum C-peptide in cases presenting with infection and pancreatitis. Our literature review revealed that in conventional FT1D, endogenous insulin secretion becomes deficient in an average of 5.3 days. Regardless of any concomitant acute pancreatitis and/or pancreas enlargement, the period until endogenous insulin secretion became deficient showed no substantial variation. This result supports the concept that progression of conventional FT1D is more rapid than that of immune checkpoint inhibitor-related FT1D, which deplete insulin secretion in approximately 2 weeks.

期刊介绍:
Diabetology International, the official journal of the Japan Diabetes Society, publishes original research articles about experimental research and clinical studies in diabetes and related areas. The journal also presents editorials, reviews, commentaries, reports of expert committees, and case reports on any aspect of diabetes. Diabetology International welcomes submissions from researchers, clinicians, and health professionals throughout the world who are interested in research, treatment, and care of patients with diabetes. All manuscripts are peer-reviewed to assure that high-quality information in the field of diabetes is made available to readers. Manuscripts are reviewed with due respect for the author''s confidentiality. At the same time, reviewers also have rights to confidentiality, which are respected by the editors. The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
