Members of the ADA Professional Practice Committee, a multidisciplinary expert committee (https://doi.org/10.2337/dc21-SPPC), are responsible for updating the Standards of Care annually, or more frequently as warranted. The implication of these findings is that there is no need to deintensify therapy for an individual with an A1C between 6% and 7% and low hypoglycemia risk with a long life expectancy. Individualized glucose targets, patient education, dietary intervention (e.g., bedtime snack to prevent overnight hypoglycemia when specifically needed to treat low blood glucose), exercise management, medication adjustment, glucose monitoring, and routine clinical surveillance may improve patient outcomes (82). In the 9-year post-DCCT follow-up of the EDIC cohort, participants previously randomized to the intensive arm had a significant 57% reduction in the risk of nonfatal myocardial infarction (MI), stroke, or cardiovascular death compared with those previously randomized to the standard arm (41). 6. With the advent of new technology, CGM has evolved rapidly in both accuracy and affordability. A1C 7% = 53 mmol/mol. 6.5a An A1C goal for many nonpregnant adults of <7% (53 mmol/mol) without significant hypoglycemia is appropriate. Participants who continued into the EDIC follow-up study were transferred to their own health care team for medical care and were encouraged to use intensive treatment. The incorporation of these metrics into clinical practice is in evolution, and optimization and harmonization of CGM terminology will evolve to suit patient and provider needs. Found inside – Page 37Ten thousand patients will be studied comparing an HbA1c of <6.0% versus < 7.5% as well as studies on controlling blood ... The recent EDIC trial data is a landmark trial in type 1 diabetes on the effects of tight glycemic control and ... E, 6.2  Assess glycemic status at least quarterly, and as needed, in patients whose therapy has recently changed and/or who are not meeting glycemic goals. Found inside – Page 34PREVIOUS MAJOR CLINICAL TRIALS Several landmark trials sponsored by the National Eye Institute were conducted in the 1970s and 1980s to determine the optimal treatment of diabetic retinopathy ( Table 1 ) . The Diabetic Retinopathy Study ... For studies targeting hypoglycemia, most studies demonstrated a significant reduction in time spent between 54 and 70 mg/dL. Glycemic control is assessed by the A1C measurement, continuous glucose monitoring (CGM), and self-monitoring of blood glucose (SMBG). may worsen glycemic control and precipitate diabetic ketoacidosis or nonketotic hyperglycemic hyperosmolar state, life-threatening conditions that require immediate medical care to prevent complications and death. The results of several PIONEER trials were announced at the 79th Scientific Sessions of the American Diabetes Association (ADA), which was held from 7 to 11 June 2019, in San Francisco, California. 0/0 Steps . It ran for twenty years (1977 to 1997) in 23 UK clinical sites and showed conclusively that the complications of type 2 diabetes, previously often regarded as . 6.2. Experts Offer "Landmark" Diabetes Exercise Recommendations. Similarly, in healthy older adults, there is no empiric need to loosen control. All three trials were conducted in relatively older participants with longer known duration of diabetes (mean duration 8–11 years) and either CVD or multiple cardiovascular risk factors. Glycemic targets must be individualized in the context of shared decision-making to address the needs and preferences of each patient and the individual characteristics that influence risks and benefits of therapy for each patient in order to optimize patient engagement and self-efficacy. Thus, A1C targets should be reevaluated over time to balance the risks and benefits as patient factors change. AstraZeneca today announced positive results from the landmark Phase III DAPA-HF trial which showed that Farxiga (dapagliflozin) met the primary composite endpoint with a statistically-significant and clinically-meaningful reduction of cardiovascular death or the worsening of heart failure (defined as hospitalisation or an urgent heart failure visit), compared to placebo. Hemoglobin variants must be considered, particularly when the A1C result does not correlate with the patient's CGM or SMBG levels. While these trials led to conclusions that GLP-1 agonists and SGLT2 inhibitors decreased risk for negative CV outcomes, the overall risk ratio compared with placebo within the black population was a nonsignificant 0.90. A landmark trial has investigated the safety of such a therapeutic approach. These findings support that premeal glucose targets may be relaxed without undermining overall glycemic control as measured by A1C. Clinical Trials for Diabetes. Adequate fluid and caloric intake must be ensured. The NIDDK funded the landmark Diabetes Control and Complications Trial (DCCT) to see if people with type 1 diabetes who kept their blood glucose levels as close to normal as safely possible with intensive diabetes treatment (three or more shots of insulin per day or an insulin pump with self-monitoring of blood glucose at least four times per day) could slow the development of eye, kidney, and nerve disease, compared with people who used the conventional treatment at the time of the study (one or two shots of insulin per day with daily self-monitoring of urine or blood glucose). 2 The health, social, and economic burdens caused by T2DM and its complications present a major . Indeed, in the recently published landmark trials of angiotensin I receptor antagonists, including the Irbesartan Diabetic Nephropathy Trial (IDNT) and Reduction of Endpoints in Non-insulin-dependent Diabetes Mellitus with the Angiotensin II Antagonist Losartan (RENAAL), multiple antihypertensive drugs were required to attain goal. Three landmark trials (Action to Control Cardiovascular Risk in Diabetes [ACCORD], Action in Diabetes and Vascular Disease: Preterax and Diamicron MR Controlled Evaluation [ADVANCE], and Veterans Affairs Diabetes Trial [VADT]) were conducted to test the effects of near normalization of blood glucose on cardiovascular outcomes in individuals with long-standing type 2 diabetes and either known cardiovascular disease (CVD) or high cardiovascular risk. In 2015, the ADA changed its preprandial glycemic target from 70–130 mg/dL (3.9–7.2 mmol/L) to 80–130 mg/dL (4.4–7.2 mmol/L). Over time, comorbidities may emerge, decreasing life expectancy and thereby decreasing the potential to reap benefits from intensive control. When EDIC began, participants who used conventional treatment were taught about intensive treatment, and received follow-up care from their own health care teams. Found inside – Page 392Two landmark trials have served as the basis for current recommendations for the management of blood glucose levels in diabetes. The Diabetes Control and Complications Trial (DCCT) was conducted in adults with type 1 diabetes and ... E. A1C reflects average glycemia over approximately 3 months. Level 1 hypoglycemia is defined as a measurable glucose concentration <70 mg/dL (3.9 mmol/L) but ≥54 mg/dL (3.0 mmol/L). Sessions on Cardiology and Infectious Diseases. In addition to traditional glucagon injection powder that requires reconstitution prior to injection, intranasal glucagon and glucagon solution for subcutaneous injection are available. Ongoing insulin activity or insulin secretagogues may lead to recurrent hypoglycemia unless more food is ingested after recovery. Adapted from Battelino et al. For type 2 diabetes, other strategies to assist patients with insulin dosing can improve A1C with minimal hypoglycemia (118). Found inside – Page 708The effects of tight glycemic control in type 2 diabetes were demonstrated in four landmark trials: • United Kingdom Prospective Diabetes Study (UKPDS) • Action to Control Cardiovascular Risk in Diabetes (ACCORD) • Action in Diabetes ... A blood glucose concentration of 70 mg/dL (3.9 mmol/L) has been recognized as a threshold for neuroendocrine responses to falling glucose in people without diabetes. Found inside – Page 93Studies comprising diabetic subgroups Several of the landmark trials with statins (see Chapter 8) had an sufficient number of patients with diabetes to allow post-hoc analysis of the effects in diabetes. The first of these, the 4S trial ... The NIDDK funded the landmark Diabetes Control and Complications Trial (DCCT) to see if people with type 1 diabetes who kept their blood glucose levels as close … For example, in a very young child safety and simplicity may outweigh the need for perfect control in the short run. A1C is the metric used to date in clinical trials demonstrating the benefits of improved glycemic control. Overall, real-time CGM appears to be a useful tool for decreasing time spent in a hypoglycemic range in people with impaired awareness. The new guidelines, published simultaneously in two leading research journals . Studies of rates of level 3 hypoglycemia that rely on claims data for hospitalization, emergency department visits, and ambulance use substantially underestimate rates of level 3 hypoglycemia (76) yet reveal a high burden of hypoglycemia in adults over 60 years of age in the community (77). Of course, progress is often cumulative, and the advances over the past 20 years were built on earlier progress, such as the 1993 landmark Diabetes Control and Complications Trial and the Lower .

As such, on the basis of physician judgment and patient preferences, select patients, especially those with little comorbidity and long life expectancy, may benefit from adopting more intensive glycemic targets if they can achieve them safely without hypoglycemia or significant therapeutic burden. LANDMARK TRIALS • Landmark trials in diabetes were … As outlined in more detail in Section 9 “Pharmacologic Approaches to Glycemic Treatment” (https://doi.org/10.2337/dc21-S009) and Section 10 “Cardiovascular Disease and Risk Management” (https://doi.org/10.2337/dc21-S010), the cardiovascular benefits of SGLT2 inhibitors or GLP-1 receptor agonists are not dependent upon A1C lowering; therefore, initiation can be considered in people with type 2 diabetes and CVD independent of the current A1C or A1C goal or metformin therapy. Care should be taken to ensure that glucagon products are not expired. The Diabetes Control and Complications Trial (DCCT) (25), a prospective randomized controlled trial of intensive (mean A1C about 7% [53 mmol/mol]) versus standard (mean A1C about 9% [75 mmol/mol]) glycemic control in patients with type 1 diabetes, showed definitively that better glycemic control is associated with 50–76% reductions in rates of development and progression of microvascular (retinopathy, neuropathy, and diabetic kidney disease) complications. Landmark clinical trials have shown that lifestyle … Found inside – Page 4pathophysiological predictions is tested in clinical trials of treatment of hypertension in people with diabetes. ... early landmark antihypertensive therapy trials, diabetic subjects were excluded from the study. Diabetes mellitus is associated with an increase in cardiovascular disease and mortality. Pure glucose is the preferred treatment, but any form of carbohydrate that contains glucose will raise blood glucose. If left untreated, diabetes can cause many health complications. Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic . More information is available at https://www.diabetesjournals.org/content/license. The Diabetes Control and Complications Trial Research Group. Analysis of the ACCORD data did not identify a clear explanation for the excess mortality in the intensive treatment arm (39). Young children with type 1 diabetes and the elderly, including those with type 1 and type 2 diabetes (73,81), are noted as particularly vulnerable to hypoglycemia because of their reduced ability to recognize hypoglycemic symptoms and effectively communicate their needs. Landmark trial demonstrates Jardiance® (empagliflozin) is the first therapy to show statistically significant improvement in heart failure outcomes in adults with preserved ejection fraction 09:18 Landmark trials in type 2 diabetes 11:36 Does tight control prevent micro or macrovascular complications 13:20 Trials of newer agents like SGLT2i, GLP-1 … Based on these considerations, the following two strategies are offered (58): 1. implications of these results on . 2. The use of glucagon is indicated for the treatment of hypoglycemia in people unable or unwilling to consume carbohydrates by mouth. These landmark studies need to be considered with an important caveat; glucagon like peptide 1 (GLP-1) receptor agonists and sodium–glucose cotransporter 2 (SGLT2) inhibitors were not approved at the time of these trials. The benefit of intensive glycemic control in this cohort with type 1 diabetes has been shown to persist for several decades (42) and to be associated with a modest reduction in all-cause mortality (43). Efforts to reduce the burden of type 2 diabetes include attempts to prevent or delay the onset of the disease. Improving Care and Promoting Health in Populations: 3. Health care, Medical and Pharmacy Concept. Building on this knowledge, many community-based studies have attempted to replicate the trial . Diabetes is a chronic disease with an estimated global prevalence of 450 million. Other assays have statistically significant interference, but the difference is not clinically significant. 3. Diabetes Drug Empagliflozin Cuts CV Deaths in Landmark EMPA-REG Trial. In an agreement trumpeted as a "landmark," major international diabetes organizations have endorsed new official guidelines for blood sugar targets during exercise for patients with Type 1 diabetes. 6.3 Standardized, single-page glucose reports from continuous glucose monitoring (CGM) devices with visual cues, such as the ambulatory glucose profile (AGP), should be considered as a standard printout for all CGM devices. Found inside – Page 78Insulin development has seen some major and landmark trials in management of diabetes, some of which remained controversial while others even 200 patients in each arm of insulin variable dose arm, insulin fixed dose arm, tolbutamide arm ... The EDIC follow-up study started in 1994, enrolling 96 percent of the living DCCT participants at the beginning of the study. Diabet. . As with my previous blog on landmark … Main trial. Landmark papers are highly influential papers that have substantially changed the practice of medicine or provided the missing evidence to support current practices. DOI: https://doi . Hypoglycemia is reversed by administration of rapid-acting glucose or glucagon. Level 2 hypoglycemia (defined as a blood glucose concentration <54 mg/dL [3.0 mmol/L]) is the threshold at which neuroglycopenic symptoms begin to occur and requires immediate action to resolve the hypoglycemic event. Caregivers, school personnel, or family members of these individuals should know where it is and when and how to administer it. Published data suggest a strong correlation between TIR and A1C, with a goal of 70% TIR aligning with an A1C of ∼7% in two prospective studies (18,27). type 2 diabetes landmark trials juvenile. This figure is not designed to be applied rigidly but to be used as a broad construct to guide clinical decision-making (59) and engage in shared decision-making in people with type 1 and type 2 diabetes. These benefits occurred despite less intensive blood sugar control after the DCCT study ended. TrialNet screening can detect risk years before symptoms appear, opening the door for early intervention with monitoring and clinical trials testing ways to prevent and delay type 1 diabetes. For patients with type 1 diabetes with level 3 hypoglycemia and hypoglycemia unawareness that persists despite medical treatment, human islet transplantation may be an option, but the approach remains experimental (84,85). Thus, for prevention of both microvascular and macrovascular complications of diabetes, there is a major call to overcome therapeutic inertia and treat to target for an individual patient (47,49). Additionally, EDIC has shown that personalizing the frequency of eye screenings for people with type 1 diabetes based on their risk of severe eye problems and A1C level would result in. The issue of preprandial versus postprandial SMBG targets is complex (60).
