Incretin-Based Drugs and the Risk of Congestive Heart Failure
February 2015. This retrospective analysis was conducted to determine whether the use of incretin-based drugs (dipeptidyl-peptidase-4 inhibitors, glucagon-like receptor-1 analogs) was associated with an increased risk of congestive heart failure (CHF) among patients with type 2 diabetes. Data were obtained from the UK Clinical Practice Research Datalink, and patients with no prior CHF history and newly prescribed to antidiabetic drug regimens between January 1, 2007, and March 31, 2012, were evaluated. The cohort comprised 57,737 patients, with a mean 2.4 years’ follow-up. Investigators found that the use of incretin-based drugs was not associated with increased CHF risk (adjusted OR 0.85 [95% CI 0.62–1.16]). The authors also indicated that these results should be verified by large-scale studies. You can follow this link to read the study abstract.

Endocrine Society Releases New Obesity Drug Treatment Guidelines
January 15, 2015. The Endocrine Society has published a guideline for the pharmacologic management of obesity in patients not achieving success with diet and exercise alone. These guidelines were developed to help providers identify patients who might benefit from pharmacotherapy for obesity and provide relevant evidence and background on available pharmacologic agents. The guidelines provide recommendations on medication use and dosage, including recommendations for patients with obesity-related comorbidities such as type 2 diabetes and cardiovascular disease. The guidelines also offer specific recommendations for transitioning patients off drugs that cause weight gain. You can follow this link to review the guidelines abstract or download the full text.
FDA Label May Prevent Use of Metformin in Some Patients With Type 2 Diabetes
December 2014. Researchers from Penn Medicine and Weill Cornel Medical College have reported that many US patients with type 2 diabetes (T2D) may be discouraged from taking metformin because the US Food and Drug Administration inappropriately labels the drug unsafe for some patients with renal impairment.

Is There a Link Between Liraglutide and Pancreatitis? A Post Hoc Review of Pooled and Patient-Level Data From Completed Liraglutide Type 2 Diabetes Clinical Trials
December 12, 2014. This study evaluated pooled data from Novo Nordisk–sponsored Phase 2 and 3 liraglutide trials to review acute and chronic pancreatitis (AP and CP) cases observed in the clinical trial program. All patients were receiving multiple medications. Among 6,345 patients treated with liraglutide, 8 AP cases were found; 1 AP case was identified from the 1,846 comparator-treated patients (patient was treated with glimepiride). However, 1 of 8 of the liraglutide AP cases did not meet diagnostic criteria; additionally, in 6 of 8 cases, recognized risk factors for AP were present and/or AP onset occurred >6 months after liraglutide initiation. Four cases of chronic pancreatitis (CP) were identified in liraglutide patients vs none with the comparator; however, only 1 of 4 of these cases fulfilled diagnostic criteria for CP. The investigators concluded that while pancreatitis cases were numerically higher with liraglutide, problems with diagnostic criteria and confounding variables preclude any ability to draw firm conclusions.

Sulfonylurea in Combination With Insulin Is Associated With Increased Mortality Compared With a Combination of Insulin and Metformin in a Retrospective Danish Nationwide Study
January 2015. This retrospective study evaluated approximately 28,000 patients to assess whether the use of sulfonylureas + insulin vs metformin + insulin is associated with more frequent episodes of hypoglycemia and increased mortality risk. Findings indicate that sulfonylurea + insulin users have an elevated risk of hypoglycemia compared with metformin + insulin users (17-23 vs 6 events per 1,000 person-years, respectively); hypoglycemia-related mortality (rate ratio [RR] 2.13, 95% confidence interval [CI] 1.97, 2.37); overall mortality (RR 1.81, 95% CI 1.63, 2.01); and cardiovascular death (RR 1.35, 95% CI 1.14, 1.60). No significant differences in outcomes were observed based on sulfonylurea type.

American Diabetes Association Releases 2015 Standards of Care
December 23, 2014. The American Diabetes Association’s (ADA’s) annual Standards of Medical Care in Diabetes has been released. Key updates include the following: Individuals with diabetes should limit sedentary time by breaking up extended amounts of time (>90 minutes) spent sitting. People with diabetes should engage in resistance training at least twice a week (unless this is not possible due to other medical reasons). The ADA has revised premeal blood glucose targets to reflect new data; the new target is 80 mg/dL to 130 mg/dL. The recommended diastolic blood pressure goal for most people with diabetes and hypertension was changed from 80 mm Hg to 90 mm Hg. Additionally, the body mass index cut point for screening Asian patients for diabetes has been changed to 23 kg/m2 (from 25 kg/m2). Last, the 2015 standards bring the ADA in line with the American College of Cardiology and American Heart Association in terms of statin use; low- or high-dose statins are recommended for all people at risk for heart disease, including those with diabetes. While the supplement is considered a single document, it is now divided into 14 individual, downloadable sections. You can follow this link to download the 2015 ADA Standards; alternately, follow this link to a summary of revisions made to the 2015 standards.

Possible Adverse Effects of SGLT-2 Inhibitors on Bone (Commentary)
December 15, 2014. A commentary in the current issue of The Lancet reviews evidence for an association between the use of sodium glucose cotransporter-2 (SGLT2) drugs and an increase in treatment-emergent bone fractures. Clinical trials have shown that this drug class is effective in lowering glucose and in weight loss; however, these benefits need to be balanced against possible side effects. No Medline abstract for this commentary is available; you can read a brief summary at The Lancet’s website
First Set of Interoperability Standards for Diabetes Devices Released
December 11, 2014. The JDRF and the Centre for Global eHealth Innovation at the University Health Network in Toronto have published the first set of interoperability standards to enable intercommunication between diabetes devices (such as blood glucose monitors, insulin pumps, and continuous glucose monitors) and other media. Inter-device connectivity has been a challenge because product manufacturers typically develop proprietary communications systems. These new standards set a definition for interoperability between devices and external computers, with the goal of establishing consistent protocols and a universal understanding of device data. You can follow this link to read a press release regarding the new interoperability standards. There is also a link to purchase the published standards.
Is There a Link Between Liraglutide and Pancreatitis? A Post Hoc Review of Pooled and Patient-Level Data From Completed Liraglutide Type 2 Diabetes Clinical Trials
December 12, 2014. This study evaluated phase 2 and 3 research conducted by Novo Nordisk to determine the incidence of acute or chronic pancreatitis (AP/CP) in patients receiving liraglutide or comparator drugs. Using data representing >8,000 patient-years, 8 AP cases were identified in liraglutide patients (7 of which met diagnostic criteria for AP), and 1 with the comparator drug glimepiride. Additionally, 4 CP cases were identified with liraglutide (1 of which met diagnostic criteria for CP) and none with comparators. The investigators concluded that pancreatitis incidence was numerically greater with liraglutide vs comparators; however, a high prevalence of confounding variables, as well as issues with diagnostic criteria, prevent any firm conclusions at this time.

Hypoglycemia and Risk of Cardiovascular Disease and All-Cause Mortality in Insulin-Treated People With Type 1 and Type 2 Diabetes: A Cohort Study
December 9, 2014. This retrospective cohort study assessed a nationally representative population to determine whether any association exists between hypoglycemia, cardiovascular (CV) events, and all-cause mortality in insulin-using patients with type 1 or type 2 diabetes (T1D/T2D). The investigators found that, regardless of whether or not patients had a history of CV disease, hypoglycemia was significantly and persistently associated with increased risk for all outcomes. Hazard ratios (HRs) for CV disease in patients with T1D were 1.51 and 1.61 for those with and without CV disease history, respectively; for patients with T2D, these respective HRs were 1.60 and 1.49. For all-cause mortality, respective HRs were 1.98 and 2.03 for T1D and 1.74 and 2.48 for T2D. For all patients, the median time from an initial hypoglycemic event to a first CV event was 1.5 years.

Pioglitazone and Bladder Cancer Risk: A Multipopulation Pooled, Cumulative Exposure Analysis
December 2014. This study evaluated several international cohorts to assess the effect of pioglitazone exposure on bladder cancer risk. Accurately assessing this risk has been difficult because of the potential for allocation bias (ie, the likelihood that patients prescribed or not prescribed pioglitazone might differ in their preexisting susceptibility to bladder cancer). To address this, the investigators applied a discrete time failure analysis using Poisson regression to model the effect of cumulative drug exposure, with time-dependent adjustment for pioglitazone use, with data subsequently pooled using fixed and random-effects meta-regression. Investigators found no evidence for an association between cumulative pioglitazone exposure and bladder cancer risk in men or women (rate ratios [RR] of 1.01 and 1.04, respectively). The authors also found no association between rosiglitazone use and bladder cancer risk (RR 1.01 and 1.00 for men and women, respectively).

The Economic Burden of Elevated Blood Glucose Levels in 2012: Diagnosed and Undiagnosed Diabetes, Gestational Diabetes Mellitus, and Prediabetes
December 2014. This article updates prior estimates of the economic burden of diagnosed, undiagnosed, and gestational diabetes, as well as prediabetes, using retrospective 2010-2012 data obtained from the Medicare Standard Analytical Files, the Optum database, and the Nationwide Inpatient Sample. Investigators found that the annual economic burden associated with diabetes exceeded $322 billion in 2012: $244 billion of this comprised excess medical costs and $78 billion was due to reduced productivity. This national estimate was 48% higher than the 2007 estimate of $218 billion. You can follow this link to review or download the full study.
Diabetes, Antidiabetic Medications, and Pancreatic Cancer Risk: An Analysis From the International Pancreatic Cancer Case-Control Consortium
October 2014. This analysis evaluated data from 15 case-control studies from the Pancreatic Case-Control Consortium (8,305 cases, 13,987 controls) to determine: the magnitude of pancreatic cancer risk in type 2 diabetes (T2D), the time-risk relationship, and the impact of antidiabetic medications. Investigators found a 30% excess risk of pancreatic cancer in T2D patients that persisted for ≥2 decades after diagnosis, suggesting a causal relationship. Oral antidiabetic drugs were associated with significantly decreased pancreatic cancer risk (odds ratio [OR]:0.31). Short-term insulin use (<5 years) was associated with significantly higher pancreatic cancer risk (OR: 5.6), but this risk did not persist with long-term (≥15 years) use (OR: 0.95, confidence intervals not statistically significant).

Effect of Hypoglycemia on Brain Structure in People With Type 2 Diabetes: Epidemiological Analysis of the ACCORD-MIND MRI Trial
December 2014. This study was designed to assess the effect of severe hypoglycemia related to type 2 diabetes (T2D) treatment on brain structure, specifically abnormal white matter (AWM) volume and total brain volume (TBV). Participants were recruited from the Action to Control Cardiovascular Risk in Diabetes-Memory in Diabetes (ACCORD-MIND) trial. Patients with ≥1 hypoglycemic event requiring assistance (n=28 of 503) were evaluated by standardized magnetic resonance imaging at baseline and 40 months. Investigators found no significant increase in AWM and only marginally significant decreases in TBV in patients who experienced hypoglycemia. The authors concluded that hypoglycemia related to T2D treatment may not substantially affect brain pathology. You can follow this link to read the full study abstract.
Dietary Intervention in Patients With Gestational Diabetes Mellitus: A Systematic Review and Meta-analysis of Randomized Clinical Trials on Maternal and Newborn Outcomes
December 2014. This systematic review and meta-analysis of randomized clinical trials was conducted to evaluate the role of dietary intervention in maternal and newborn outcomes in pregnancies complicated by gestational diabetes (GD) or hyperglycemia. Nine studies (N=884) were eligible for inclusion and evaluated the following diet types: low glycemic index, total energy restriction, low carbohydrate, and others. Investigators found that a low glycemic index diet was the most appropriate intervention in this population; compared with control diets, this approach was associated with reduced insulin use and lower infant birth weight.

Type 2 Diabetes and Cardiovascular Disease Incidence: A Cohort Study of 1.9 Million People
November 11, 2014. This large, United Kingdom-based cohort study evaluated 1,921,260 individuals to determine the association between type 2 diabetes (T2D) and 12 initial manifestations of cardiovascular disease (CVD). The investigators found that peripheral arterial disease was the most common early manifestation of CVD in patients with T2D (hazard ratio [HR] 2.98). Other CVD manifestations significantly associated with T2D were ischemic stroke (HR 1.72), stable angina (1.62), heart failure (1.56), and nonfatal myocardial infarction (1.54).

Superior Glycemic Efficacy With Dapagliflozin vs Glipizide in T2DM With Poor Glycemic Control on Metformin Alone
November 2014. This 52-week, randomized, double-blind study evaluated dapagliflozin vs glipizide as add-on therapies to metformin. The study included a double-blind extension period, and data up to 104 weeks are reported in this paper. Initially, glipizide treatment led to decreased A1C levels vs dapagliflozin; however, at study end, A1C reductions with dapagliflozin were -0.18% vs glipizide, and patients treated with dapagliflozin lost -5.1 kg more weight vs glipizide and reduced systolic blood pressure by -3.9 mmHg over glipizide. They also had a 10-fold lower rate of hypoglycemic events. Glipizide use was associated with weight gain and increased blood pressure. Patients taking dapagliflozin experienced higher rates of genital and urinary tract infections. To read the full study abstract, follow this link.
Competitive Accuracy of 3 Blood Glucose Monitoring Systems That Communicate With an Insulin Pump
November 2014. Published in Endocrine Practice, this study compared the accuracy of 3 blood glucose monitoring systems capable of communicating wirelessly with an insulin pump: the Contour® Next Link; OneTouch® UltraLink®; and the Nova Max Link™. The primary endpoint was accuracy across the full glucose testing range (34 to 561 mg/dL). Secondary analyses evaluated low (≤80 mg/dL) and high (>180 mg/dL) glucose ranges, as well as mean absolute relative difference. Across the entire tested range, investigators found that the Contour® Next Link had significantly better accuracy than the other 2 devices.

Patients Using Metformin Have Increased Survival Compared With Nondiabetic Controls
November 2014. This retrospective observational study evaluated whether all-cause mortality is higher in patients with type 2 diabetes (T2D) treated with either sulfonylurea or metformin vs matched, untreated patients without diabetes. Overall, 78,241 patients receiving metformin, 12,222 receiving sulfonylureas, and 90,463 nondiabetic matched patients (representing 503,384 follow-up years) were evaluated. Progression to all-cause mortality was analyzed using parametric survival models, with T2D patients receiving metformin serving as the reference group. Investigators found that adjusted median survival time was 38% lower for sulfonylurea patients and 15% lower for nondiabetic patients. The authors noted that these finding reinforce current recommendations for metformin as first-line therapy in T2D, highlight the possible risks associated with sulfonylureas, and indicate that metformin may be associated with independent benefits.

Sulfonylurea Use and Incident Cardiovascular Disease Among Patients With Type 2 Diabetes: Prospective Cohort Study Among Women
November 2014. Because inconsistent evidence exists regarding the relationship between cardiovascular risk and sulfonylurea use in patients with type 2 diabetes (T2D), this study prospectively evaluated this association using data from the Nurses’ Health Study. A total of 4,902 women (mean age 68 years, mean diabetes duration 11 years; no patients had cardiovascular disease at baseline) were followed for up to 10 years. Investigators found that long-term sulfonylurea use was associated with an increased risk of coronary heart disease (P = 0.002 for trend). The relative risk for coronary heart disease among patients receiving sulfonylurea therapy over 1-5, 6-10, and >10 years, respectively, was 1.24, 1.51, and 2.15 (compared to patients who did not use sulfonylureas).

A Position Statement of the American Diabetes Association: Care of Young Children With Diabetes in the Child Care Setting
October 2014. The American Diabetes Association (ADA) has released a position statement on the care of young children with diabetes in child care settings. This statement was drafted in recognition of a lack of diabetes management guidance in day care settings. It focuses primarily on young people with type 1 diabetes—the predominant diabetes diagnosis in this age group. The ADA states that these children can be safely cared for by child care providers who have received appropriate training and have access to needed resources, including an effective communication system with the child’s parents and healthcare provider. As part of this statement, the ADA has developed a sample diabetes child care management plan, as well as other resources and tools available online at http://www.diabetes.org/childcare. You can download a full copy of the Position Statement by following this link.
EDITION 2 Study: Insulin Glargine 300 Units/mL vs Glargine 100 Units/mL in People With Type 2 Diabetes
September 5, 2014. This 6-month, multicenter, open-label, 2-arm study evaluated glucose control and hypoglycemia in adults (n=811) with type 2 diabetes (T2D) receiving insulin glargine 300 U/ml/day vs glargine 100 U/ml/day alongside treatment with oral agents and basal insulin. The primary endpoint was the change in A1C levels; a secondary endpoint was the percentage of participants with ≥1 confirmed cases of nocturnal hypoglycemia (≤70 mg/dL) or severe hypoglycemia. Investigators found that both glargine formulations were equally effective in terms of glucose control, with each leading to A1C reductions of approximately -0.6%. However, glargine 300 was associated with a significantly lower rate of nighttime and overall hypoglycemic events vs glargine 100 (hazard ratio: 0.77; 95% CI 0.61-0.99).

ADVANCE Trial: Follow-up of Blood-Pressure Lowering and Glucose Control in Type 2 Diabetes
October 9, 2014. The factorial trial, Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE), found that combination therapy with the blood pressure-lowering medications perindopril and indapamide reduced mortality in patients with type 2 diabetes (T2D), but that intensive glucose control (A1C target <6.5%) did not. This study reports on a subsequent 6-year follow-up of surviving ADVANCE participants (n=8494) and evaluated the primary endpoints of death from any cause and major macrovascular events. Investigators found that mortality benefits persisted in an attenuated form in patients previously treated with perindopril-indapamide (hazard ratios of 0.91 [P=0.03] and 0.88 [P=0.04] for death from any cause and cardiovascular death, respectively). There were no observable long-term effects of prior intensive glucose control. You can follow this link to read the study abstract.
Randomization to a Low-Carbohydrate Diet Improves Health-Related Quality of Life Compared With a Low-Fat Diet With Similar Weight-Loss in Patients With Type 2 Diabetes
September 21, 2014. This study compared the 2-year impact of a low-fat vs low-carbohydrate diet in 61 patients with type 2 diabetes (baseline mean body mass index 32.7 kg/m2). At 6 months, both patient groups had similar weight loss (~4 kg); this was sustained for the duration of the trial. At 6 months, patients receiving the low-carbohydrate intervention experienced improved ratings on the SF-36 questionnaire physical function component. By 12 months, low-carbohydrate patients showed improvements in the measure’s physical function, bodily pain, and general health score components, with no significant changes in SF-36 component scores for the low-fat diet group at any time.

Liraglutide and the Preservation of Pancreatic Beta-Cell Function in Early Type 2 Diabetes
September 23, 2014. This 48-week, double-blind, randomized, placebo-controlled trial evaluated whether liraglutide preserved beta-cell function in patients (N=51) with type 2 diabetes (T2D) diagnosed a mean of 2.6 years previously. Because clinical studies of beta-cell function can be compromised by an inability to estimate baseline glucose function, patients in this trial were provided with short-term intensive insulin therapy to eliminate glucotoxicity before randomization. The primary outcome was performance on an oral glucose tolerance test known as the Insulin Secretion-Secretory Index-2 (ISSI-2), evaluated every 12 weeks. At 48 weeks, baseline-adjusted ISSI-2 was significantly higher in the liraglutide vs placebo group. These beneficial effects were lost within 2 weeks of stopping liraglutide treatment. You can follow this link to read the study abstract.
Weight-Loss Therapy in Type 2 Diabetes: Effects of Phentermine and Topiramate Extended-Release
September 23, 2014. This study evaluated the safety and efficacy of phentermine/extended- release topiramate (PHEN-TPM ER) treatment for obesity (alongside lifestyle modification) in 2 clinical trials of patients with type 2 diabetes (T2D). Results from two 56-week studies were evaluated: OB-202/DM-230 (N=130) and CONQUER (subpopulation analysis, n=388). In OB-202/DM-230, weight loss at 56 weeks was -9.4% for PHEN-TPM ER and -2.7% for placebo. In both trials, patients achieved their A1C targets with a reduced need for glucose-lowering medications compared with placebo-treated patients. Click this link to read the study abstract.

FDA Approves Dulaglutide to Treat Type 2 Diabetes
September 18, 2014. The US Food and Drug Administration (FDA) has approved dulaglutide (trade name: Trulicity™), a new glucagon-like peptide-1 receptor agonist. Dulaglutide is administered as a once-weekly subcutaneous injection to improve glycemic control, alongside diet and exercise, in adults with type 2 diabetes. The FDA will require several post-marketing studies of dulaglutide, including a case registry to track medullary thyroid carcinoma incidence, an evaluation of the drug in pediatric patients, a cardiovascular (CV) outcomes trial in patients with high baseline CV risk, and a study comparing dulaglutide vs insulin glargine in patients with moderate or severe renal impairment. Dulaglutide also has a boxed warning regarding thyroid gland tumors observed in rodent studies. Follow this link to read the full FDA press release.
Glucagon-like Peptide-1 Receptor Agonist and Basal Insulin Combination Treatment for Management of Type 2 Diabetes
September 12, 2014. This systematic review and meta-analysis evaluated the effect of combined treatment with a glucagon-like peptide-1 (GLP-1) receptor agonist and basal insulin on glucose control, hypoglycemia, and weight gain in patients with type 2 diabetes (T2D). Fifteen eligible studies were identified and included in the analysis (N=4348 patients). GLP-1/basal insulin combination treatment led to improved A1C levels compared with other medication regimens evaluated (including full basal-bolus insulin replacement), did not increase hypoglycemia risk, and led to substantial mean weight reductions. The authors concluded that this treatment option could improve the management of patients with T2D. You can follow this link to read the full study abstract.

Multicenter Closed-Loop Insulin Delivery Study Points to Challenges for Keeping Blood Glucose in a Safe Range in Adults and Adolescents with Type 1 Diabetes
July 8, 2014. The Control to Range Study was a multinational evaluation of a closed-loop artificial pancreas to assess the time spent by adults and adolescents with type 1 diabetes (N=53) in hypoglycemic and hyperglycemic states (target glucose ranges: 70 to 180 mg/dL). Mean glucose levels for adults were 159 mg/dL, with 66% of values in the target range (59% daytime, 82% overnight). Adolescents’ mean glucose levels were 166 mg/dL, with 62% of values in range (53% daytime, 82% overnight). Investigators concluded that the system performed as expected, and that both groups evaluated met prespecified safety criteria. However, the system’s performance was better overnight than during the daytime, and it was difficult to prevent some postmeal excursions from exceeding target range.

Adding Rapid-Acting Insulin or GLP-1 Receptor Agonist to Basal Insulin: Outcomes in a Community Setting
August 22, 2014. This retrospective matched database analysis, reported in Endocrine Practice, evaluated add-on therapy with a glucagon-like peptide-1 (GLP-1) receptor agonist vs rapid-acting insulin in patients with type 2 diabetes (T2D) already on basal insulin. Compared with rapid-acting insulin, the use of a GLP-1 receptor agonist was associated with fewer hospitalizations and lower total all-cause costs. Hypoglycemic event rates were similar in both groups. The investigators concluded that adding a GLP-1 receptor agonist provided an alternative to rapid-acting insulin treatment in patients with T2D not achieving glycemic control with basal insulin alone.

Glucagon-Like Peptide 1 Receptor Agonist or Bolus Insulin With Optimized Basal Insulin in Type 2 Diabetes
July 2014.This 30-week, open-label, randomized, multicenter, noninferiority trial compared the efficacy and safety of the glucagon-like peptide-1 receptor agonist exenatide vs insulin lispro in patients with type 2 diabetes (N=627) with inadequately controlled A1C levels on basal insulin plus metformin. Both treatments resulted in similar glycemic control. Patients receiving exenatide experienced weight loss, compared to weight gain with lispro. Exenatide recipients also had fewer nonnocturnal hypoglycemic events but more gastrointestinal events. The investigators concluded that these findings support the use of exenatide as a noninsulin add-on therapy for patients failing basal insulin. Click here to read the study abstract.
Type 1 Diabetes Mellitus and Cardiovascular Disease: A Scientific Statement From the American Heart Association and American Diabetes Association
August 11, 2014. The majority of published data on cardiovascular disease (CVD) in diabetes is focused on the treatment of type 2 diabetes (T2D). Additionally, most literature regarding CVD and type 1 diabetes (T1D) was conducted when glycemic control standards were less stringent than today. This review from the American Heart Association and American Diabetes Association focuses on the importance of CVD in patients with T1D. It summarizes recent evidence suggesting potential differences in the pathophysiology of atherosclerosis in T1D and T2D, as well as the implications of these findings for treatment decision-making. The statement also identifies knowledge gaps and summarizes areas for future research. Follow this link to download the full article.
Effects of Intensive Glycemic Control on Ischemic Heart Disease: Analysis of Data From the ACCORD Trial
August 1, 2014. This analysis of the randomized controlled ACCORD (Action to Control Cardiovascular Risk in Diabetes) trial evaluated 10,251 adults with established type 2 diabetes (T2D) and risk factors for ischemic heart disease, assigned to standard or intensive glycemic control for a mean of 3.7 years. The investigators found that risk for several ischemic events including myocardial infarction, coronary revascularization, and unstable angina was significantly lower (risk reduction range, 11% to 20%) in intensively treated patients. The authors concluded that elevated glucose levels are a modifiable risk factor for ischemic heart disease in this high-risk population of patients with T2D.

Liraglutide Reverses Pronounced Insulin-Associated Weight Gain, Improves Glycemic Control, and Decreases Insulin Dose in Patients With Type 2 Diabetes
June 2014. This 26-week randomized controlled trial was designed to evaluate whether the addition of the glucagon-like peptide-1 (GLP-1) analogue liraglutide to insulin therapy could reverse insulin-mediated weight gain and maintain glycemic control in patients with type 2 diabetes. Fifty patients were randomized to receive add-on open-label liraglutide (n=26) or to continue standard insulin therapy (n=24). Investigators found that body weight decreased by 4.5 kg with liraglutide and increased by 0.9 kg with standard therapy (P<0.001). Patients receiving liraglutide also experienced additive A1C reductions and reduced insulin requirements compared to those on standard therapy (-0.77% vs +0.01% and -29 U/day vs +5 U/day; P<0.001 for both). Liraglutide was tolerated well by patients, with no severe adverse events or severe hypoglycemia. Link here to read the study abstract.

Factors Associated With Weight Gain in People With Type 2 Diabetes Starting on Insulin
August 2014. This study evaluated 2179 individuals with type 2 diabetes who initiated insulin therapy in 314 centers across 12 countries. At 1 year, analyses were conducted to identify factors predictive of weight gain. Mean overall patient weight gain was 1.78 kg, and 24% of patients gained 5 kg or more. The factors found to be independently associated with weight gain were high baseline A1C, high insulin dose requirements, and lower baseline BMI. Patients’ insulin regimen was not a predictive factor. To read the full study abstract, Click here.
Treatment of Type 2 Diabetes in the Older Adult: A Review
July 2014. This review, published in the July edition of Endocrine Practice, summarizes available evidence regarding the unique challenges associated with treating diabetes in older patients and provides guidance to select treatment strategies and targets. Older patients with type 2 diabetes are a highly heterogeneous population, and multiple factors (eg, patient comorbidities, diabetes duration, and functional status) need to be taken into consideration as part of treatment decision-making. Hypoglycemia is more common in older patients, and a lack of consensus exists regarding optimal glycemic targets. Based on this, the authors emphasize the importance of individualized pharmacologic therapy and call for more clinical pharmacotherapy trials in this population.

Statins and the Risk of Diabetes: Evidence From a Large Population-Based Cohort Study
June 26, 2014. This large cohort study (N=115,709) investigated the relationship between statin therapy adherence and diabetes risk, with adherence measured as proportion of days covered (PDC). Participants were residents of the Italian Lombardy region who initiated statin treatment in 2003-2004. Participants were followed until 2010. During this time, those who initiated anti-diabetic therapy or who were hospitalized with a primary diagnosis of type 2 diabetes (T2D) were considered to have met the primary outcome (n=11,154). The investigators found that greater adherence to statin therapy was associated with an elevated risk of T2D development. Specifically, compared with patients with very-low adherence to statin therapy (PDC <25%), those with low (26%-50%), intermediate (51%-75%), and high (≥75%) adherence had the following hazard ratios (95% confidence intervals) for diabetes diagnosis: 1.12 (1.06-1.18), 1.22 (CI: 1.14-1.27), and 1.32 (CI: 1.26-1.39), respectively.

Effect of Intensive Diabetes Treatment on Albuminuria in Type 1 Diabetes
July 18, 2014.This long-term follow-up of the Diabetes Control and Complications Trial and Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study in individuals with type 1 diabetes found that a history of intensive diabetes treatment yielded durable renal benefits that persisted over 18 years of follow-up. Specifically, patients provided with intensive treatment during the DCCT experienced a 45% risk reduction for microalbuminuria, as well as a 44% risk reduction for sustained estimated glomerular filtration rate <60 mL/min per 1.73m2. The investigators noted that such benefits should result in fewer patients requiring renal replacement therapy. Follow this link to read the full study abstract.

Glucagon-Like Peptide-1 Receptor Agonist or Bolus Insulin With Optimized Basal Insulin in Diabetes
July 10, 2014. Although it is common to add mealtime insulin when basal supplementation becomes inadequate, this treatment approach can be associated with weight gain and hypoglycemia. This 30-week, open-label, multicenter, randomized noninferiority trial evaluated 627 patients with diabetes with insufficient A1C optimization following 12 weeks of insulin treatment; all patients were already receiving insulin glargine and metformin. Patients were randomized to exenatide (10-20 μg/day) or mealtime insulin lispro administered 3 times daily and titrated to a fasting plasma glucose level of 101 to 108 mg/dL. The investigators found that the exenatide regimen led to similar glycemic control levels as insulin lispro (-1.13% and -1.10%, respectively) and was well tolerated by patients.

Whey Protein Before Meals Reduced Blood Sugar Spikes in Type 2 Diabetes
July 2014. Because protein intake is known to stimulate glucagon-like peptide-1 (GLP-1) secretion, this study was conducted to determine whether preloading with a whey protein supplement might have beneficial glucose-lowering effects in type 2 diabetes (T2D). This randomized trial of 15 patients not currently receiving any medications except for sulfonylurea and metformin was conducted in a hospital setting. Patients who consumed 50 g of whey protein (dissolved in water) before a high-glycemic-index breakfast experienced increased early prandial and late insulin secretion, augmented GLP-1 response, and reduced postprandial glycemia. The investigators speculated that whey protein might enhance existing glucose-lowering strategies in T2D. You can follow this link to the home page of Diabetologia to download the full article.
A Randomized, Controlled Open-Label Study of Insulin Pump Therapy in Patients With Type 2 Diabetes
July 3, 2014. Prior research comparing the efficacy of insulin pump use vs multiple daily injections (MDI) in insulin-treated patients with type 2 diabetes (T2D) have yielded inconclusive results. This randomized, controlled trial (OpT2mise) of patients with T2D and poor glycemic control was conducted in 36 centers in North America, Europe, South Africa, and Israel. Mean A1C level at baseline was 9% and decreased by 1.1% at 6 months for pump-treated patients compared with 0.4% for MDI patients (between-group difference -0.7%, P<0.0001). Additionally, mean total daily insulin dose at study end was 97 units for pump users vs 122 units for MDI (P<0.0001). Click here to read the full study abstract.
Effect of Insulin Analogues on Risk of Severe Hypoglycemia in Patients With Type 1 Diabetes Prone to Recurrent Severe Hypoglycemia
May 2014. This randomized, open-label, blinded endpoint crossover trial was conducted at 7 medical centers in Denmark to determine whether treatment with insulin analogues (detemir and aspart) in patients with type 1 diabetes with recurrent severe hypoglycemia led to a reduction in rates of severe hypoglycemia vs human insulin. Investigators found that treatment with insulin analogues was associated with an absolute risk reduction of 0.51 hypoglycemic episodes per patient-year (95% confidence interval, 0.19 to 0.84).

Liraglutide, Lifestyle Changes Reversed Prediabetes, Delayed Type 2 Diabetes Onset
June 22, 2014. Results from the SCALE (Effect of Liraglutide on Body Weight in Non-diabetic Obese Subjects or Overweight Subjects With Co-morbidities) study were presented at the 16th International Congress of Endocrinology and the Endocrine Society. This randomized controlled study (N=3731) evaluated liraglutide 3.0 mg, in conjunction with lifestyle changes, in patients with overweight/obesity plus ≥1 additional risk factor (such as prediabetes, high blood pressure, or cholesterol). By the end of the initial 56-week study period, patients receiving liraglutide lost an average of 8% of their body weight (18.7 pounds) compared with 2.6% (6.2 pounds) in patients receiving placebo. Additionally, ~70% of patients with prediabetes receiving liraglutide transitioned to normoglycemia, compared with 32% of those receiving placebo (P <0.0001). A 2-year extension study is now planned.

American Diabetes Association Sets New A1C Target for Children With Type 1 Diabetes
June 16, 2014. In a new position statement released at the American Diabetes Association’s (ADA) 74th Scientific Sessions, the ADA announced that it is decreasing recommended target blood glucose levels for youth with type 1 diabetes (T1D). The ADA now recommends that youth under 19 years of age with T1D maintain an A1C level <7.5%; previous targets were as high as 8.5%, dependent on age. This new target was set because of concerns over complications caused by prolonged hypoglycemia (ie, cardiovascular and kidney disease). New evidence indicates that prolonged hypoglycemia risk is elevated in children who maintain higher A1C levels over time.

Long-term Follow-up of Diabetes Prevention Program Shows Continued Reduction in Diabetes Development
June 16, 2014. Fifteen-year findings from the Diabetes Prevention Program (DPP) were reported at the American Diabetes Association’s (ADA) 74th Annual Scientific Sessions. Investigators noted that interventions used to delay the development of type 2 diabetes (T2D) continued to be effective over time. Specifically, patients originally assigned to 3 years of lifestyle intervention or metformin treatment continued to have reduced rates of progression to T2D (27% and 17%, respectively) compared with patients originally assigned to placebo. It is important to note that, after the trial’s active phase, all DPP participants were provided with access to lifestyle intervention, leading to a reduction in differences among the treatment groups. The DPP investigators also reported on outcomes for microvascular complications and cardiovascular disease risk factors.

Outpatient Glycemic Control With a Bionic Pancreas in Type 1 Diabetes
June 15, 2014. A 5-day outpatient trial has demonstrated that a wearable, bihormonal "bionic pancreas" improves glycemic control and decreases hypoglycemia in patients with type 1 diabetes (T1D). In this study, 20 adults and 32 adolescents with T1D took part in 2 random-order, crossover studies, using an insulin pump as control therapy. Automated glycemic management (ie, insulin and glucagon delivery) was controlled for the bionic pancreas by a continuous glucose monitor using an adaptive algorithm. Both adults and young patients experienced statistically significant declines in glucose levels, as well as less frequent hypoglycemia (for adults) and reduced frequency of hypoglycemia-related interventions (adolescents). These results were reported simultaneously at the American Diabetes Association 74th Annual Scientific Sessions and published in the New England Journal of Medicine.

Incidence of Pancreatitis and Pancreatic Cancer in a Randomized Controlled Multicenter Trial (SAVOR-TIMI 53) of the Dipeptidyl Peptidase-4 (DPP-4) Inhibitor Saxagliptin
June 9, 2014. This study evaluated the incidence of pancreatitis and pancreatic cancer in the SAVOR-TIMI 53 trial (Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus-THrombolysis in Myocardial Infarction) over 2.1 years of follow-up. In this study, patients (N=16,492) with type 2 diabetes (T2D) and established cardiovascular (CV) disease or CV risk factors were randomized to treatment with saxagliptin or placebo. In both groups, similar, low rates of pancreatitis (26 events in the saxagliptin arm and 25 events in the placebo arm), and low rates of pancreatic cancer (5 and 12 cases in the saxagliptin and placebo arms, respectively) were found. Study investigators concluded that saxagliptin has no signal for increased pancreatitis or pancreatic cancer risk. You may follow this link to read the study abstract.
Comparison of Insulin Degludec/Insulin Aspart and Biphasic Insulin Aspart 30 in Uncontrolled, Insulin-Treated Type 2 Diabetes: A Phase 3a, Randomized, Treat-to-Target Trial
May 8, 2014. This 26-week randomized open-label trial compared insulin degludec/insulin aspart (IDegAsp) with biphasic insulin aspart 30 (BIAsp 30) in 446 adults with inadequately controlled type 2 diabetes (T2D). At study end, patients who received IDegAsp and BIAsp 30 had similar A1C levels; however, IDegAsp patients had significantly lower fasting plasma glucose and mean daily insulin dose, as well as fewer confirmed episodes of hypoglycemia than those who took BIAsp 30.

Outcomes of Combined Cardiovascular Risk Factor Management Strategies in Type 2 Diabetes
March 4, 2014. This analysis of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) assessed standard vs intensive control of glucose, blood pressure (BP), and lipids on cardiovascular (CV) outcomes in 10,521 patients with type 2 diabetes (T2D). Compared with standard treatment, the risk for nonfatal myocardial infarction, nonfatal stroke, or death due to CV disease was lower in groups intensively treated for glucose (HR, 0.67; 95% CI, 0.50–0.91), blood pressure (HR, 0.74; 95% CI, 0.55–1.00), or both (HR, 0.71; 95% CI, 0.52–0.96). Researchers did not find any benefit with an intensive lipid control regimen. These results suggest that intensive blood pressure or glycemic control decreases the risk of major CV outcomes in patients with T2D. Click here to read the study abstract.
Da Qing Diabetes Prevention Study, 23-Year Follow-up: Cardiovascular and All-Cause Mortality and Diabetes Incidence After Lifestyle Intervention
June 2014. This follow-up analysis assessed the long-term impact of lifestyle intervention on mortality outcomes (cardiovascular [CV] and all-cause) and diabetes incidence in the Da Qing Diabetes Prevention Study. Patients (N=577) with impaired glucose tolerance enrolled in 1986 and were followed for 6 years; in 2009, investigators followed up with patients to assess their outcomes. Cumulative CV mortality was 11.9% in the intervention group vs 19.6% in the control group (P=0.033); all-cause mortality was 28.1% vs 38.4% (P=0.049); and diabetes incidence was 72.6% vs 89.9%, respectively (P=0.001). The investigators noted that these findings provide additional support regarding the critical role of lifestyle intervention in patients with impaired glucose tolerance.

3-Year Data: Exenatide Once-Weekly vs Insulin Glargine for Type 2 Diabetes (DURATION-3)
April 4, 2014. This randomized, open-label, multisite, 3-year extension of the DURATION-3 trial compared exenatide once weekly (2 mg subcutaneous injection) to daily insulin glargine in 456 insulin-naïve patients with type 2 diabetes (T2D). Patients receiving exenatide experienced significant A1C reductions compared with those on insulin glargine (-1.01% vs -0.81%, P=0.03). Serious adverse event rates overall were the same between the 2 groups, although exenatide patients were more likely to report transient gastrointestinal adverse events. Additionally, the overall hypoglycemia rate was approximately 3 times higher with insulin glargine. Investigators concluded that exenatide treatment is a viable option in T2D patients who have not yet transitioned to insulin therapy. Follow this link to read the study abstract.

Hypoglycemia Increases Arrhythmia Risk in Type 2 Diabetes
May 2014. Recent clinical trials of intensive glycemic control in type 2 diabetes (T2D) have suggested a link between hypoglycemia and excess cardiovascular (CV) mortality. To investigate this, researchers evaluated the impact of simultaneous continuous interstitial glucose and ambulatory electrocardiogram monitoring in 25 insulin-treated patients with T2D and a history of CV disease or ≥2 CV risk factors. Measurements including arrhythmia frequency, heart rate variability, and markers of cardiac repolarization were compared between hypoglycemia and euglycemia and between hyperglycemia and euglycemia matched for time of day. They found that hypoglycemia mediated by vagal activation following the counterregulatory phase might increase arrhythmia risk in these patients. This could contribute to increased CV mortality during intensive glycemic therapy. Click here to read the study abstract.
New Studies Show Liraglutide Works in Obesity and Type 1 Diabetes
May 18, 2014. Data presented at the American Association of Clinical Endocrinologists’ (AACE) 23rd Annual Scientific and Clinical Congress indicate that liraglutide works as both an add-on to insulin in type 1 diabetes (T1D), as well as a weight loss agent in people without diabetes. In a randomized controlled trial, liraglutide (1.2 mg and 1.8 mg) significantly improved both A1C and fasting glucose in patients with T1D vs placebo. Data were also presented for liraglutide 3.0 mg in patients who were overweight (plus ≥1 comorbidity) or obese. In this study, patients had significantly greater mean body weight loss with liraglutide vs placebo (-8.0% vs -2.6%, P<0.0001).

AACE Announces an Advanced Framework for a New Medically Actionable Diagnosis of Obesity
May 16, 2014. At its 23rd Annual Scientific and Clinical Congress, the American Association of Clinical Endocrinologists (AACE) and American College of Endocrinology (ACE) announced the release of an advanced framework for a new diagnostic and management approach to obesity. This framework emerged from the AACE/ACE Consensus Conference on Obesity, convened in March 2014, and argues that the current diagnostic definition of obesity (primarily reliant on an anthropomorphic measure of body mass index [BMI]) needs to be updated. This new definition does not depend upon BMI alone, but also the impact of weight gain on health. A 4-step approach is recommended for all patients: 1) screening using BMI with adjustments for ethnic differences; 2) clinical evaluation for the presence of obesity-related complications using a checklist; 3) staging for the severity of complications using complication-specific criteria; and 4) selection of prevention and/or intervention strategies targeting specific complications, as guided by the AACE/ACE obesity management algorithm. Follow this link to view the AACE press release related to the framework document. In addition, this link will lead you to a full draft of the comprehensive framework document.
Comprehensive Study Reveals Valuable Data About Diabetes in US Hispanic/Latino Populations
May 15, 2014. Data presented at the American Association of Clinical Endocrinologists’ (AACE) 23rd Annual Scientific and Clinical Congress outlined results from a comprehensive, multiyear medical research study examining health issues among US Hispanic/Latino groups. Findings indicate that less than half of these patients with diagnosed diabetes had the condition under control, and approximately one-third of patients with diabetes did not know they had this disease. The study also revealed significant differences in diabetes prevalence across Hispanic groups: the disease was most common among individuals of Mexican, Puerto Rican, and Dominican origin and least prevalent among those from South America. The Hispanic Community Health Study/Study of Latinos, spearheaded by the National Heart, Lung, and Blood Institute, recruited and examined more than 16,000 participants in 4 cities from 2008 to 2011 to identify risk factors that play a role in the development of cardiovascular and other diseases in Hispanics/Latinos. The study is ongoing. Link here to read an AACE press release summarizing the trial’s findings.
Efficacy and Safety of Insulin Lispro in Obese Patients With Type 2 Diabetes: Retrospective Meta-analysis of 7 Randomized Controlled Trials
May 2014. This retrospective analysis of 7 randomized controlled trials was designed to assess the efficacy and safety of insulin lispro administered to obese (≥30 kg/m2) vs non-obese patients (<30 kg/m2) with type 2 diabetes mellitus (T2DM). Both obese and non-obese patients experienced similar A1C reductions (~1.0%); however, the incidence and rate of hypoglycemia were significantly lower in obese vs non-obese patients (incidence: 53% vs 63%; rate: 0.93 vs 1.76 events per 30 days).

Nocturnal Hypoglycemia May Increase Arrhythmia Risk in Type 2 Diabetes
May 2014. In this study, 25 insulin-treated patients with type 2 diabetes and at high cardiovascular risk received simultaneous interstitial glucose and ambulatory electrocardiogram monitoring. The frequency of arrhythmias, heart rate variability, and cardiac repolarization markers were compared against the timing of hyperglycemia, hypoglycemia, and euglycemia. The investigators found that arrhythmias were more common during nighttime vs daytime hypoglycemia and proposed that excessive compensatory vagal activation following the counterregulatory phase might account for these findings.

Up to One-third of Obese Children May Be Metabolically Healthy
February 26, 2014. According to a recent cross-sectional analysis of 8- to 17-year-olds with body mass index ≥85th percentile, up to 1 in 3 children with obesity may potentially be metabolically healthy. Study participants were classified as metabolically healthy or unhealthy based on insulin resistance and cardiometabolic risk factors and with multivariate logistic regression used to identify variables predictive of metabolically healthy obesity (these included waist circumference, dietary fat intake, and moderate-to-vigorous physical activity). The investigators noted that these findings may help providers determine which patients require health services prioritization. Click here to read the study abstract.
Midlife Type 2 Diabetes and Poor Glycemic Control Are Risk Factors for Cognitive Decline in Early Old Age
March 2014. In this post-hoc analysis of the United Kingdom Whitehall II cohort study, 5653 participants (median age 54.4 years) were categorized into 4 groups: normoglycemic, prediabetes, newly diagnosed diabetes, and existing diabetes. Cognitive tests were administered to participants 3 times over 10 years. Compared with normoglycemic participants, those with known diabetes had faster declines in memory (45%; P=0.046), reasoning (29%; P=0.026), and global cognitive score (24%; P =0.014). Participants with prediabetes or newly diagnosed diabetes had similar rates of decline as those with normoglycemia. Link here to review the study abstract.

Cardiovascular Risk Profile in Patients With Prediabetes and New-Onset Type 2 Diabetes Identified by A1C Testing
February 26, 2014. This study evaluated the cardiovascular (CV) risk profile of 274 patients with prediabetes and newly diagnosed type 2 diabetes (based on A1C testing). Patients also received fasting plasma glucose (FPG) and oral glucose tolerance testing (OGTT). Investigators found that patients with prediabetes based on A1C level, but with normal FPG and OGTT results, had an altered intima-media thickness and augmentation index. These data suggest that A1C testing may be better than FPG or OGTT alone in identifying prediabetic patients at high CV risk. To read the study abstract, click here.

ACCORD MIND Study: No Diabetes or Dementia Benefit From Blood Pressure Control or Fibrate Treatment
February 2014. This analysis of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Memory in Diabetes (MIND) trial evaluated high-risk type 2 diabetes mellitus (T2DM) patients (N=2977) with no evidence of dementia or cognitive impairment at baseline. Patients were randomized to intensive or conventional blood pressure (BP) control (<120 mm Hg or <140 mm Hg, respectively) or to treatment with fibrate vs placebo. Patient cognition was tested at baseline, 20, and 40 months. Neither BP control or fibrate therapy significantly impacted cognitive decline at 40 months, although a sub-study of total brain volume (TBV) found that intensive BP control was associated with a lower decline in TBV compared with standard treatment.

Type 2 Diabetes Prevention: Which Approaches Work Best?
January 29, 2014. This systematic review and meta-analysis evaluated the effectiveness of different strategies to prevent type 2 diabetes mellitus (T2DM). Seventy-one controlled trials and 15 diabetes prevention strategies were included in the analysis. Evaluated interventions included diet and physical activity, specific antidiabetic and cardiovascular/lipid-lowering drugs, certain nutrients, estrogens, alcohol, and bariatric surgery. Investigators found that lifestyle and several drugs (with the exception of beta-cell stimulating drugs) were effective in preventing T2DM, with statistically significant odds ratios (ORs) ranging from 0.37 to 0.85. The most effective strategy was bariatric surgery (OR 0.16) in morbidly obese patients. Follow this link to read the study abstract.
Medicare’s Diabetes Testing Supply Program Is Limiting Patient Choice and Access
January 2014. A study conducted by the American Association of Diabetes Educators (AADE) suggests that Medicare's Competitive Bidding Program for mail-order diabetes testing supplies is limiting beneficiaries' access. Specifically, AADE contacted 23 eligible Medicare mail-order diabetes testing suppliers and found that only 3 suppliers carried each brand of diabetes testing supplies they reported having, while no suppliers had more than 50% of the product offerings listed on the Medicare website. AADE concluded that Medicare beneficiaries have reduced choice and access to diabetes testing supplies as a result of the Competitive Bidding Program. The full study report can be downloaded from the AADE website.
A1C Test Can Be Used Early to Detect Diabetes Risk
November 2013. This community-based historic cohort study followed 10,201 patients who were at high risk for, but not diagnosed with, type 2 diabetes mellitus (T2DM) at baseline. Patients’ A1C levels were measured at baseline and over the subsequent 5 to 8 years. Investigators found that A1C levels ≥5.5% were associated with increased T2DM risk and noted that these data support the use of A1C testing as a screening tool in high-risk populations.
