利拉鲁肽治疗2型糖尿病的临床研究进展

利拉鲁肽是一种新型胰高糖素样肽-1 GLP-1类似物,能迅速、高效、持久地降低血糖及糖化血红蛋白,具有改善胰岛β细胞功能、调节收缩压、保护心血管、降低血脂、减轻体重、延迟胃排空、增加饱腹感等作用。此外,利拉鲁肽具有葡萄糖依赖的促胰岛素分泌作用,仅在机体血糖水平高时刺激胰岛素的释放,但当患者体内血糖浓度恢复至正常时,GLP-1分泌促胰岛素的作用便消退,因而发生低血糖事件的几率较低,能有效地改善糖尿病患者的病情,已成为目前2型糖尿病治疗领域的研究热点。本文主要就利拉鲁肽治疗2型糖尿病的临床研究进展进行综述。

Induction of insulin secretion in engineered liver cells by nitric oxide

Background  

Type 1 Diabetes Mellitus results from an autoimmune destruction of the pancreatic beta cells, which produce insulin. The lack of insulin leads to chronic hyperglycemia and secondary complications, such as cardiovascular disease. The currently approved clinical treatments for diabetes mellitus often fail to achieve sustained and optimal glycemic control. Therefore, there is a great interest in the development of surrogate beta cells as a treatment for type 1 diabetes. Normally, pancreatic beta cells produce and secrete insulin only in response to increased blood glucose levels. However in many cases, insulin secretion from non-beta cells engineered to produce insulin occurs in a glucose-independent manner. In the present study we engineered liver cells to produce and secrete insulin and insulin secretion can be stimulated via the nitric oxide pathway.     

Ideglira is Associated With Improved Short-Term Clinical Outcomes and Cost Savings Compared With Insulin Glargine U100 Plus Insulin Aspart in the U.S.

Objective: In the DUAL (Dual Action of Liraglutide and Insulin Degludec in Type 2 Diabetes) VII trial, IDegLira (a combination of insulin degludec and liraglutide) was compared with insulin glargine U100 plus insulin aspart. Both treatment approaches achieved similar glycemic control, but there were differences in hypoglycemia, changes in body weight, and injection frequency. The aim of the present analysis was to assess the short-term cost effectiveness of IDegLira versus insulin glargine U100 plus insulin aspart for treatment of patients with type 2 diabetes mellitus not meeting glycemic targets on basal insulin in the U.S. setting.Methods: A cost-utility model was developed to evaluate the clinical and economic outcomes associated with the 2 treatments over a 1-year time horizon, capturing the impact on quality of life of hypoglycemic events, body mass index, and injection frequency. Costs were captured from a healthcare payer perspective in 2017 U.S. dollars ($).Results: IDegLira was associated with improved quality of life by 0.12 quality-adjusted life years compared with insulin glargine U100 plus insulin aspart. The key drivers of this difference were reduced injection frequency and hypoglycemic events avoided. IDegLira was associated with increased annual drug costs, but this was entirely offset by reduced needle costs and reduced costs of self-monitoring of blood glucose testing. IDegLira was associated with total annual cost savings of $743 per patient.Conclusion: IDegLira was found to improve quality-adjusted life expectancy and reduce costs when compared with insulin glargine U100 plus insulin aspart for treatment of patients with type 2 diabetes not achieving glycemic control on basal insulin in the U.S. setting.Abbreviations: ADA = American Diabetes Association; BMI = body mass index; CI = confidence interval; DUAL = Dual Action of Liraglutide and Insulin Degludec in Type 2 Diabetes; GLP-1 = glucagon-like peptide-1; HbA1c = glycated hemoglobin; ICER = incremental cost-effectiveness ratio; IU = international units; QALY = quality-adjusted life year; SMBG = self-monitoring of blood glucose     

Hypoglycemia: Still The Limiting Factor in the Glycemic Management of Diabetes

ObjectiveTo review the prevalence of, risk factors for, and prevention of hypoglycemia from the perspective of the pathophysiologic aspects of glucose counterregulation in diabetes.MethodsThis review is based on personal experience and research and the relevant literature.ResultsAlthough it can result from insulin excess alone, iatrogenic hypoglycemia is generally the result of the interplay of therapeutic insulin excess and compromised defenses against declining plasma glucose concentrations. Failure of β-cells of the pancreas—early in patients with type 1 diabetes mellitus but later in those with type 2 diabetes mellitus (T2DM)—causes loss of the first 2 physiologic defenses: a decrease in insulin and an increase in glucagon. Such patients are critically dependent on epinephrine, the third physiologic defense, and neurogenic symptoms that prompt the behavioral defense (carbohydrate ingestion). An attenuated sympathoadrenal response to declining glucose levels—caused by recent antecedent hypoglycemia, prior exercise, or sleep—causes hypoglycemia-associated autonomic failure (HAAF) and thus a vicious cycle of recurrent hypoglycemia. Accordingly, hypoglycemia is infrequent early in T2DM but becomes increasingly more frequent in advanced (absolutely endogenous insulin-deficient) T2DM, and risk factors for HAAF include absolute endogenous insulin deficiency; a history of severe hypoglycemia, hypoglycemia unawareness, or both; and aggressive glycemic therapy per se.ConclusionBy practicing hypoglycemia risk reduction— addressing the issue, applying the principles of aggressive glycemic therapy, and considering both the conventional risk factors and those indicative of HAAF— it is possible both to improve glycemic control and to minimize the risk of hypoglycemia in many patients.

Evolution of a pulmonary insulin delivery system (Exubera) for patients with diabetes

Many patients with diabetes fail to meet recommended glycemic goals regardless of the recognition of optimal glycemic control as a key component for improving clinical outcomes and quality of life in patients with diabetes. Patient- and physician-related barriers to the adoption of insulin therapy include fear and anxiety about injecting insulin, concerns about side effects, and personal health beliefs in regard to the use of insulin. There is an unmet need for an alternative insulin therapy that provides optimal glycemic control, is well tolerated, and improves patient adherence. Of the several inhaled insulin devices that are in various stages of development, the Exubera (INH) formulation is the first to be approved for use in the United States and in Europe. Exubera is a novel, rapid-acting inhaled human insulin formulation that has been developed for prandial insulin use. Clinical studies have shown that INH consistently improves glycemic control, in combination with longer-acting subcutaneous (SC) insulin regimens in patients with type 1 or type 2 diabetes, or is used to supplement or replace oral antidiabetic therapy in patients with type 2 diabetes. INH has demonstrated long-term safety and tolerability, with a risk for hypoglycemia similar to that of SC insulin, and no clinically meaningful changes in pulmonary function have been noted with its use. Patients treated with INH in clinical studies reported high levels of satisfaction with treatment, and many patients with diabetes choose inhaled insulin when it is offered as a treatment option. Taken together, these findings suggest that INH represents an important new development in the treatment of diabetes that may improve glycemic control in many patients with diabetes.     

Regulating insulin signaling and beta-cell function through IRS proteins

Diabetes mellitus is a complex disorder that arises from various causes, including dysregulated glucose sensing and impaired insulin secretion (maturity onset diabetes of youth, MODY), autoimmune-mediated beta-cell destruction (type 1), or insufficient compensation for peripheral insulin resistance (type 2). Type 2 diabetes is the most prevalent form that usually occurs at middle age; it afflicts more than 30 million people over the age of 65, but is appearing with greater frequency in children and adolescents. Dysregulated insulin signaling exacerbated by chronic hyperglycemia promotes a cohort of systemic disorders--including dyslipidemia, hypertension, cardiovascular disease, and female infertility. Understanding the molecular basis of insulin resistance can prevent these disorders and their inevitable progression to type 2 diabetes.     

De-Intensification of Diabetes Treatment in Elderly Patients with Type 2 Diabetes Mellitus

Objective: De-intensification of diabetes treatment is recommended in elderly patients with tight glycemic control at high risk of hypoglycemia. However, rates of de-intensification in endocrine practice are unknown. We conducted a retrospective study to evaluate the rate of de-intensification of antidiabetic treatment in elderly patients with type 2 diabetes mellitus (T2DM) and tight glycemic control.Methods: All patients with ≥2 clinic visits over a 1-year period at a major academic diabetes center were included. De-intensification of diabetes treatment was defined as a decrease or discontinuation of any antidiabetic drug without adding another drug, or a reduction in the total daily dose of insulin or a sulfonylurea drug with or without adding a drug without risk of hypoglycemia.Results: Out of 3,186 unique patients, 492 were ≥65 years old with T2DM and hemoglobin A1c (HbA1c) <7.5% (<58 mmol/mol). We found 308 patients treated with a sulfonylurea drug or insulin, 102 of whom had hypoglycemia as per physician note. Among these 102 patients, 38 (37%) were advised to de-intensify therapy. In a subgroup analysis of patients ≥75 years old with HbA1c <7% (<53 mmol/mol), we found that out of 23 patients treated with a sulfonylurea drug or insulin and reporting hypoglycemia, 11 (43%) were advised de-intensification of therapy. There were no significant predictors of de-intensification of treatment.Conclusion: Our study suggests that de-intensification of antidiabetic medications is uncommon in elderly patients with T2DM. Strategies may need to be developed to prevent the potential harm of overtreatment in this population.Abbreviations: ADA = American Diabetes Association; CGM = continuous glucose monitoring; HbA1c = hemoglobin A1c; T2DM = type 2 diabetes mellitus; UKPDS = United Kingdom Prospective Diabetes Study     

Association between Responsible Pet Ownership and Glycemic Control in Youths with Type 1 Diabetes

Type 1 diabetes mellitus (T1DM) a chronic characterized by an absolute insulin deficiency requires conscientious patient self-management to maintain glucose control within a normal range. Family cohesion and adaptability, positive coping strategies, social support and adequate self-regulatory behavior are found to favorably influence glycemic control. Our hypothesis was that the responsible care of a companion animal is associated with these positive attributes and correlated with the successful management of a chronic illness such as type 1 diabetes. We recruited 223 youths between 9 and 19 years of age from the Pediatric Diabetes clinic at the University of Massachusetts Medical School, reviewed the status of their glycemic control (using three consecutive A1c values) and asked them questions about the presence of a pet at home, and their level of involvement with its care. Multivariate analyses show that children who care actively for one or more pets at home are 2.5 times more likely to have control over their glycemic levels than children who do not care for a pet, adjusting for duration of disease, socio-economic status, age and self-management [1.1 to 5.8], p_Wald = 0.032. A separate model involving the care of a petdog only yielded comparable results (OR_a = 2.6 [1.1 to 5.9], p_Wald = 0.023).     

Appropriate,timely, and rational treatment of type 2 diabetes mellitus: Meeting the challenges of primary care

Diabetes now affects >24 million people in the United States. As the prevalence of diabetes continues to increase, long-term complications of diabetes have emerged as major health care issues. Although much focus has been placed on diabetes, it is important to note that prediabetes, the intermediate state of type 2 diabetes mellitus (DM), is not benign. The progression to type 2 DM for patients with impaired glucose tolerance (IGT) is 6% to 10% per year; for persons with both impaired fasting glucose and IGT, the cumulative incidence of diabetes in 6 years may be as high as 60%. Given the significant clinical and financial impact of both conditions, it is vital that clinicians initiate treatment of diabetes and prediabetes early and aggressively. Despite advances in diabetes treatment, many health care providers do not initiate or intensify therapy appropriately during patient visits, which contributes to poor diabetes control. Although management of blood pressure and lipid levels can be complex, glycemic control is often problematic for patients and their clinicians. Thus, clinicians must learn to use the various pharmacologic and nonpharmacologic strategies effectively to achieve glucose targets in their patients with type 2 DM. Patients with prediabetes should be managed with a combination of lifestyle intervention and appropriately timed pharmacotherapy. Pancreatic β-cell preservation should be a primary metabolic target.     

Shift work and diabetes – A systematic review

Diabetes mellitus is a chronic disease, which has an increasing trend all over the world. Type 2 diabetes constitutes 90% of all diabetes. It is associated with weight gain and insulin resistance. Research during recent years has suggested that shift work could be a risk factor of type 2 diabetes. Since shift work is becoming more common, it could contribute to the increasing trend of diabetes. In this systematic review, we have studied the potential association between shift work and type 2 diabetes. We have also reviewed studies on control of diabetes in relation to shift work.
