Improvement in insulin sensitivity following intensive insulin therapy and association of glucagon with long-term diabetes remission

چکیده
Objective To investigate the role of the acute glucagon response in the long-term remission of newly diagnosed type 2 diabetes mellitus following short-term intensive insulin therapy (IIT). Methods Ten patients with newly diagnosed type 2 diabetes mellitus received IIT. Intravenous glucose tolerance tests and the clamp technique were performed pre- and post-IIT. Remission was defined as maintenance of target glycaemic control without anti-diabetic agents for 1 year. Results The remission rate was 50% (5/10). There were no differences in the acute insulin response or glucose infusion rate between groups. The acute glucagon response (AGR) in the remission group pre-IIT was significantly higher than that in the non-remission group (mean 163.02 pg/mL/min vs. mean 16.29 pg/mL/min). The mean AGR post-IIT was lower in the remission group than that in the non-remission group (0 pg/mL/min vs. 19.91 pg/mL/min). Spearman analysis indicated that the AGR pre-IIT and the change in the AGR were correlated with remission (r = 0.731). Conclusion The insulin-mediated glucose disposal rate was significantly improved with the normalization of blood glucose levels following transient IIT. Subjects with a higher AGR pre-IIT and a greater AGR decrease post-IIT displayed a greater likelihood of long-term remission.

Predictors of sustained drug-free diabetes remission over 48 weeks following short-term intensive insulin therapy in early type 2 diabetes
OBJECTIVE In early type 2 diabetes (T2DM), short-term intensive insulin therapy (IIT) for 2-4 weeks can decrease insulin resistance, reduce glucagonemia, improve β-cell function, and even induce a remission of diabetes that can last up to 1 year in some patients. However, little is known about the predictors of such a sustained remission. METHODS We evaluated data from the placebo arm of a do...
متن کاملGlucagon-like peptide-1 gene therapy in obese diabetic mice results in long-term cure of diabetes by improving insulin sensitivity and reducing hepatic gluconeogenesis.
Long-term treatment with glucagon-like peptide (GLP)-1 or its analog can improve insulin sensitivity. However, continuous administration is required due to its short half-life. We hypothesized that continuous production of therapeutic levels of GLP-1 in vivo by a gene therapy strategy may remit hyperglycemia and maintain prolonged normoglycemia. We produced a recombinant adenovirus expressing G...

OBJECTIVE The optimal approach to relatively recent onset type 2 diabetes patients is still unknown. We speculated that the use of short-acting insulin analogs might be of particular benefit in this context. PATIENTS AND METHODS To explore this possibility, we compared the effect on beta- and alpha-cell function of transient intensive insulin therapy using lispro versus human regular insulin ...

Roux-en-Y gastric bypass (RYGB) surgery leads to substantial and sustained weight loss and improved cardiometabolic parameters in obese people (1). Approximately 80% of patients with type 2 diabetes (T2D) experience complete remission, defined as normoglycemia without medication, and another 15% have improvement, albeit remaining on medication (2). These rates are superior to those seen with co...

OBJECTIVE To examine the effect of intensive glycemic control therapy (IT) on insulin sensitivity and β-cell function in newly diagnosed type 2 diabetic patients compared with subjects with normal glucose tolerance (NGT) and those with impaired glucose tolerance (IGT). RESEARCH DESIGN AND METHODS Forty-eight newly diagnosed type 2 diabetic patients were randomly assigned to IT for 2 weeks and...
