Abstract

Background: We evaluated the incidence, characteristics and insulin independence of Koreans with new-onset type 2 diabetes (T2D) initially presenting with diabetic ketoacidosis (DKA). Methods: We analysed clinical and biochemical data from diabetic patients presenting with DKA. They were classified into ketosis-prone diabetes (KPD) type 1A (KPD-T1A) (A+β-), type 1B (KPD-T1B) (A-β-), type 2A (KPD-T2A) (A+β+) or type 2B (KPD-T2B) (A-β+) according to the presence or absence of an autoantibody and β-cell reserve. Changes in therapy after insulin discontinuation were evaluated for up to 4years. We also compared clinical and biochemical characteristics between newly diagnosed T2D patients presenting with DKA and previously diagnosed T2D patients presenting with DKA. Results: Among 60 newly diagnosed KPD patients, 18, 21 and 21 patients were classified as KPD-T1A, KPD-T1B and KPD-T2B, respectively. In the KPD-T2B group, both fasting and stimulated C-peptide were recovered over 6months. After 4years of DKA development, 75% of KPD-T2B subjects no longer required insulin. Compared with previously diagnosed T2D patients presenting with DKA, newly diagnosed KPD-T2B patients tended to be younger, more obese and showed better insulin secretory function after recovery from DKA. Conclusions: New-onset T2D patients presenting with DKA was not uncommon among the Korean population. In contrast to previously diagnosed T2D patients presenting with DKA, who showed a progressive decrease in insulin secretory function, new-onset KPD-T2B patients recovered insulin secretory function over time, and insulin independence could be expected.
