Beneficial effects of insulin on glycemic control and beta-cell function in newly diagnosed type 2 diabetes with severe hyperglycemia after short-term intensive insulin therapy.

ABSTRACT: To evaluate whether treatment with insulin is advantageous compared with oral antidiabetes agents in newly diagnosed type 2 diabetes with severe hyperglycemia after short-term intensive insulin therapy.Newly diagnosed type 2 diabetic patients with severe hyperglycemia were hospitalized and treated with intensive insulin injections for 10-14 days. The oral glucose tolerance test (OGTT) was performed after intensive insulin treatment. After discharge, the patients were randomized to receive either insulin injections or oral antidiabetes drugs (OADs) for further management. The OGTT was repeated 6 months later, and beta-cell function and insulin sensitivity were evaluated again. These subjects were continually followed up for another 6 months to evaluate their long-term glycemic control.At the 6th month of the study, the A1C level was significantly lower in the insulin group than in the OAD group (6.33 +/- 0.70% vs. 7.50 +/- 1.50%; P = 0.002). During the follow-up visit, the A1C level was still better in the insulin group (6.78 +/- 1.21% vs. 7.84 +/- 1.74%; P = 0.009). All parameters regarding beta-cell function measured in the OGTT were improved significantly in both groups after 6 months of treatment. Compared with the OAD group, the homeostasis model assessment of beta-cell function index, insulin area under the curve, and insulinogenic index were better in the insulin group.A 6-month course of insulin therapy, compared with OAD treatment, could more effectively achieve adequate glycemic control and significant improvement of beta-cell function in new-onset type 2 diabetic patients with severe hyperglycemia.

Project description:OBJECTIVE:To assess the efficacy and safety of short- term intensive hypoglycemic therapy with a triple regimen consisting of metformin, sagliptin and dapagliflozin in patients with newly diagnosed type 2 diabetes mellitus with hemoglobin Alc (HbA1c) of 9%-12%. METHODS:We prospectively enrolled 58 patients with newly diagnosed type 2 diabetes, who were treated with metformin combined with sagliptin and dapagliflozin for 12 weeks on the basis of diabetic diet and regular exercise. Blood glucose was monitored during the treatment and the changes in HbA1c, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPBG), fasting insulin (FINS), 2-hour postprandial insulin (2 hPINS), fasting C-peptide (F-CP), 2-hour postprandial C-peptide (2 hP-CP), and body weight after treatment as well as the incidence of hypoglycemia and adverse events associated with the treatment were recorded. RESULTS:Two patients withdrew from the study for intolerance of gastrointestinal reactions, and another 2 withdrew for inconvenience of access to the medicines. Fifty-four of the patients finally completed the study, including 34 male and 20 female patients. After 12 weeks of therapy, all the patients showed significant improvements in FBG, 2 hPBG, HbA1c, HOMA-beta and HOMA-IR (P < 0.001) with a mean reduction of HbA1c level by (4.19 ± 1.07)%, and the goal of HbA1c control to below 7.0% was achieved in 83.33% of the patients. The reduction of HbA1c was correlated with FBG (r=0.487, P=0.000), 2 hPBG (r=0.310, P=0.023), and HOMA-? (r=-0.398, P=0.003). The patients had a mean body weight loss by 2.47±3.38 kg (P < 0.001) and a mean decrease of body mass index (BMI) by 0.90± 1.18 kg/m2 (P < 0.001) after the therapy. The body weight-reducing effect was associated with the patients' baseline body weight (r=0.678, P=0.000), BMI (r=0.818, P=0.000), F-CP (r=0.282, P=0.039) and HOMA-IR (r=0.297, P=0.029). During the therapy 8 patients experienced hypoglycemic symptoms (10 times, 14.81%); 3 patients were diagnosed with hypoglycemia (blood glucose ?3.9 mmol/L, 3 times), and the overall incidence of hypoglycemia was 5.56%. No serious hypoglycemia or infections of the urinary and reproductive systems occurred in these patients. CONCLUSIONS:Short-term intensive oral hypoglycemic therapy with metformin combined with sagliptin and dapagliflozin is effective for treatment of patients with newly diagnosed type 2 diabetes with HbA1c of 9%-12% and shows a good weight-reducing effect with a low risk of hypoglycemia. The combined therapy can effectively improve ?-cell insulin secretion function, and is suitable for treatment of newly diagnosed type 2 diabetic patients with high blood glucose.
