The patient was a 76-year-old, male who was diagnosed with high blood glucose at 30 years of age. He suffered a stroke at 52 years of age. and was diagnosed with type 2 diabetes at a nearby hospital. Oral hypoglycemic medicines were administered along with diet and exercise therapy, which resulted in good glycemic control. The patient required an emergency hospital admission in December 2010 for weight loss. In addition, he suffered from frequent urination. He was diagnosed with diabetic ketoacidosis based on the following findings: blood glucose, 1,003 mg/dL; glycated hemoglobin, 7.7%; positive urine ketone bodies; and blood gas pH, 7.293. Although he had previously received medical treatment, the patient was transferred to our hospital, as he was unable to achieve stable glycemic control. At the time of admission, level of blood glucose and fasting serum C peptide were 1.002 mg/dL and 0.1 ng/mL, respectively. A glucagon loading test performed at our hospital revealed a serum C peptide level of <0.5 ng/ml. Tests for islet-cell autoantibodies were negative, and the patient's pathological conditions met the diagnostic criteria for fulminant type 1 diabetes. His human leukocyte antigen genotype was DRB1*0405 DQB1*0401, which is a disease susceptibility haplotype. In our experience, acute exacerbation of fulminant type 1 diabetes is observed in elderly patients who receive treatment following a diagnosis of type 2 diabetes. The differential diagnosis of ketoacidosis in elderly patients with type 2 diabetes should also include fulminant type 1 diabetes. Furthermore, providing an appropriate diagnosis and rapid treatment intervention is required.

Cardiovascular autonomic neuropathy (CAN) is a debilitating condition occurring among diabetic patients especially those with long duration of disease. Whereas incidences and treatment of CAN has been well described for Western populations, fewer studies have been conducted among the Chinese. This study, therefore, aimed to assess the prevalence of CAN among sampled Chinese diabetic patients. Accordingly, 2,048 participants with a history of type 1 diabetes mellitus (T1DM, 73) and type 2 diabetes mellitus (T2DM, 1975) were randomly sampled from 13 hospitals. Patients' biodata were recorded, and autonomic nervous system function tests performed to aid in the preliminary diagnosis of CAN. The final CAN diagnosis was based on the Ewing's test in which heart rate variation (HRV) values were evaluated through deep-breathing (DB), lying-to-standing (LS), and Valsalva (V) tests. Systolic blood pressure (SBP) variation values were also evaluated through LS. In the T1DM group, 61.6% patients were diagnosed with CAN and no differences were observed in the baseline and clinical data between this group and those without CAN (P > 0.05). In the T2DM group, 62.6% patients were diagnosed with CAN and statistically significant differences were found between the CAN and non- CAN group with regards to age, duration of diabetes, metformin treatment, retinopathy, and hypertension history (P < 0.05). The most common manifestations of CAN included weakness (28.6%), dizziness (23.4%), frequent urination (19.6%), upper body sweating (18.3%), and nocturia (15.9%). Additionally, duration of disease and age were independent risk factors for CAN in T1DM and T2DM, respectively. On diagnosis, a combination of the V test + LS test provided the highest sensitivity of detecting CAN among T1DM group (sensitivity = 97.6%, AUC = 0.887) while for T2DM category, DB test had the highest sensitivity (83.6%), and maximal AUC (0.856) was found with V test + DB test. The overall prevalence of diabetes with CAN in the study was up to 63%.
