Objective: Type 2 diabetes with obesity is regarded as an incurable, progressive disease with many complications. The hypothesis was tested that glycated haemoglobin (HbA1c) and the insulin release curve can be restored by traceable systematic methods. Methods: 122 people with diabesity were investigated before and after three and 6 months of traceable systematic management methods. Basal body mass index (BMI), fatty liver, HbA1c, and insulin release curve were measured. Results: After 3 months of traceable systematic management, BMI decreased from 30.76 ± 0.48 to 21.86 ± 0.09 kg/m2 (p < 0.001) and remained stable during the last 3 months (21.82 ± 0.09 kg/m2 at 6 months). Colour Doppler ultrasound showed non-alcoholic fatty liver disease (NAFLD) in all diabesity participants at baseline. At 3 months, only one participant had low-grade fatty liver, and fatty liver was reversed in other participants (p < 0.001). The number and grade of fatty liver at 6 months were the same as at 3 months. Fasting plasma glucose decreased and continued to decrease thereafter (p < 0.001). Two-hour postprandial plasma glucose decreased and continued to decline until 6 months (p < 0.001). HbA1c also decreased and maintained this level at 6 months. At baseline, the peak value of insulin release was 1,141.09 ± 43.02 pmol/L at 2 h after meals, and the early phase of insulin secretion was lost. After 3 months of management, the insulin concentration was 621.62 ± 19.32 pmol/L at 2 h after meals. After 6 months, the value decreased, and the early phase of insulin secretion recovered. Conclusions: Normalization of the insulin release curve in type 2 diabetes was achieved by traceable systematic methods. This was associated with recovery from NAFLD. Diabesity is reversible by traceable systematic management. [ABSTRACT FROM AUTHOR]

Background: Cardiovascular outcomes in clinical trials with type 2 diabetes mellitus (T2DM) patients have shown that glucagon-like peptide-1 receptor agonist can have a beneficial effect on the kidney. This trial aimed to assess the effects of exenatide on renal outcomes in patients with T2DM and diabetic kidney disease (DKD). Methods: We performed a randomized parallel study encompassing 4 general hospitals. T2DM patients with an estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 and macroalbuminuria, defined as 24-h urinary albumin excretion rate (UAER) >0.3 g/24 h were randomized 1:1 to receive exenatide twice daily plus insulin glargine (intervention group) or insulin lispro plus glargine (control group) for 24 weeks. The primary outcome was the UAER percentage change from the baseline after 24 weeks of intervention. The rates of hypoglycemia, adverse events (AEs), and change in eGFR during the follow-up were measured as safety outcomes. Results: Between March 2016 and April 2019, 92 patients were randomized and took at least 1 dose of the study drug. The mean age of the participants was 56 years. At baseline, the median UAER was 1,512.0 mg/24 h and mean eGFR was 70.4 mL/min/1.73 m2. After 24 weeks of treatment, the UAER percentage change was significantly lower in the intervention group than in the control group (p = 0.0255). Moreover, the body weight declined by 1.3 kg in the intervention group (the difference between the 2 groups was 2.7 kg, p = 0.0001). Compared to the control group, a lower frequency of hypoglycemia and more gastrointestinal AEs were observed in the intervention group. Conclusion: Exenatide plus insulin glargine treatment for 24 weeks resulted in a reduction of albuminuria in T2DM patients with DKD. [ABSTRACT FROM AUTHOR]

Early evaluation of β-cell dysfunction of hyperglycemic patients in asymptomatic adults would be valuable for timely prevention of the diabetes. This study aimed to evaluate functional changes in the pancreas using intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) and determine whether it could be used as a non-invasive method of assessing β-cell dysfunction. This prospective cohort study was conducted from August 2022 to November 2022 in Jinan University Affiliated Guangdong Second General Hospital. Three groups were enrolled and underwent IVIM-DWI: confirmed patients with type 2 diabetes (T2DM); hyperglycemic patients in asymptomatic adults; and the volunteers with normal glucose tolerance (NGT). Imaging parameters were obtained: apparent diffusion coefficient (ADC), the true diffusion coefficient (D t), the pseudo-diffusion coefficient (D p), and the perfusion fraction (f). The β-cell function indexes were calculated from blood examinations: composite insulin sensitivity index (ISI), 60-min insulinogenic index (IGI60), and the disposition index (DI). We compared imaging parameters among three groups, calculated the diagnostic performance of them for differentiating different groups, and the reproducibility of them was evaluated using intraclass correlation coefficient (ICC). The imaging parameters except f gradually decreased among the groups with significant differences for ADC (p < 0.0001), D t (p < 0.0001), and D p (p = 0.013). D t demonstrated the best diagnostic performance for differentiating asymptomatic patients from NGT (Area Under Curve [AUC] = 0.815, p < 0.0001). IVIM-DWI parameters correlated with composite ISI and DI, of which, D t has the highest correlation with DI (Pearson correlation coefficient [r] = 0.546, p < 0.0001). The ICC of IVIM-DWI parameters was very good, D t was highest (Interobserver ICC = 0.938, 95% Confidence Interval [CI], 0.899–0.963; Intraobserver ICC = 0.941, 95% CI, 0.904–0.965). IVIM-DWI is a non-invasive quantitative method that can identify β-cell dysfunction in the pancreas. [ABSTRACT FROM AUTHOR]
