Anti-PD-L1 therapy and the onset of diabetes mellitus with positive pancreatic autoantibodies.

An 84-year-old woman with metastatic squamous cell carcinoma of the nasopharynx and no history of diabetes was started on the antiprogrammed cell death ligand-1 (anti-PD-L1) antibody durvalumab. Four months later, she presented in diabetic ketoacidosis with glucose 488 mg/dL, anion gap 16, positive serum ketones and A9.1%.

Can we go beyond surrogates?

Two years ago, data presented at the annual American Diabetes Association (ADA) meeting in New Orleans showed a marked decrease in deaths, especially those due to cardiovascular disease, with the use of empagliflozin. Two major questions have been asked: (i) was the result a fluke; and (ii) was it a class effect, or was it specific to the agent used? The hope that both questions would be answered by a second study has been answered: the conclusions of EMPA-REG were not an anomaly and it is a class effect, not one caused by a specific drug. Importantly, do these studies require us to alter our algorithms for the treatment of type 2 diabetes? The CANagliflozin cardioVascular Assessment Study (CANVAS) was designed similarly to EMPA-REG, enrolling individuals who either had known cardiac disease or were at high risk for cardiac disease.

Assessing the Performance of a Noninvasive Glucose Monitor in People with Type 2 Diabetes with Different Demographic Profiles.

Background: Noninvasive glucose-monitoring devices represent an exciting frontier in diabetes research. GlucoTrack® is a noninvasive device that indirectly measures glucose fluctuation in the earlobe tissue. However, GlucoTrack measurements may be susceptible to effects of quasi-stable factors that may be affected by demographic profiles.

Pilot study using mobile health to coordinate the diabetic patient, diabetologist, and ophthalmologist.

In the United States, more than 25 million adults have diabetes, 40% of diabetics have diabetic retinopathy, and diabetes is the leading cause of blindness in people 20 to 74 years of age. Clinical trials have shown that strict control of blood glucose level and other risk factors delays diabetic retinopathy onset, progression, and vision loss. Patients with Type 1 or Type 2 diabetes mellitus, access to an Apple iPhone or iPad, and no psychological or medical condition that would interfere with the study participated in a nonrandomized clinical trial using SightBook™, a free mobile app that enables self-measurement of visual function and creates a password-protected web account for each patient.

Diabetic ketoacidosis and hyperglycemic hyperosmolar state.

Diabetic ketoacidosis (DKA) and the hyperglycemic hyperosmolar state (HHS) are potentially fatal hyperglycemic crises that occur as acute complications of uncontrolled diabetes mellitus. The authors provide a review of the current epidemiology, precipitating factors, pathogenesis, clinical presentation, evaluation, and treatment of DKA and HHS. The discovery of insulin in 1921 changed the life expectancy of patients with diabetes mellitus dramatically.

Who needs an artificial pancreas? (？).

The development of a closed-loop "artificial pancreas" would be a welcome advance for both endocrinologists and diabetic patients struggling to attain near normal glycemic control. While great strides in automatically controlling blood sugar in the fasting, sedentary state have been made through complex mathematical modeling, management of blood sugar excursions due to food and exercise have been more problematic. An artificial pancreas is not feasible at this time because of limitations inherent in the currently available technology.

What role will 'gliptins' play in glycemic control?

The gliptins, a new class of oral drugs for type 2 diabietes mellitus, lower blood glucose levels by a novel mechanism: ie, by inhibiting the enzyme dipeptidyl peptidase 4, thereby increasing the circulating levelsof incretins (gut hormones that can boost insulin levels). This article reviews the current evidence on the effectiveness of gliptins and suggests several ways in which these agents could be used in diabetes treatment.

Evaluating the cardiovascular effects of the thiazolidinediones and their place in the management of type 2 diabetes in relation to the metabolic syndrome.

Background: The aim of this work was to review evidence on the contribution of the metabolic syndrome to diabetes and atherosclerosis, to evaluate the effects of the thiazolidinediones (TZDs) on cardiovascular risk, and to assess the clinical use of TZDs and their associated risks and benefits.

Methods: Participants were a multidisciplinary panel of experts in endocrinology, cardiology, and nephrology. Available studies on hyperglycemia, hyperinsulinemia, beta-cell function, dyslipidemia, obesity, hypertension, inflammation, endothelial dysfunction, and vascular reactivity were reviewed through presentations by the experts.

Update on diabetes diagnosis and management.

Background: The American Diabetes Association has established recommendations for the testing of undiagnosed people. Once diagnosed, those with diabetes must strive to maintain a level of glucose control that results in a metabolism that approaches that of people without diabetes. The dentist also can provide risk-reduction strategies for people prone to develop diabetes, and refer patients with signs and symptoms suggestive of diabetes to physicians.

Constructing an algorithm for managing type 2 diabetes. Focus on role of the thiazolidinediones.

With the understanding of type 2 diabetes mellitus constantly evolving, and with the introduction of many new agents during the past few years, it is often difficult to keep up to date with the management of type 2 diabetes. This article reviews the pathophysiology of type 2 diabetes, oral pharmacologic treatment, and proposed diabetes treatment algorithms, which aim to guide clinicians in the use of thiazolidinediones (TZDs) earlier in the course of diabetes. This is important because studies indicate that sulfonylureas, biguanides, and insulin do not protect the beta cell and cannot provide sustainable glycemic control.

Lessons learned from landmark trials of type 2 diabetes mellitus and potential applications to clinical practice.

Landmark studies have demonstrated that diabetes is a significant risk factor for cardiovascular disease and mortality. Strong relationships exist between insulin resistance/hyperglycemia and mortality, microvascular complications, and cardiovascular complications. Lipid abnormalities frequently associated with type 2 diabetes and insulin resistance include low high-density lipoprotein cholesterol (HDL-C) and elevated triglyceride levels.
