Abstract
BACKGROUND The prevalence of diabetes is increasing, and several new drug groups have been authorized and used successfully in the treatment of diabetes, while older drug groups are still in use. Our aim was to assess the utilization tendencies and regional differences in antidiabetic medication consumption in Hungary between 2015 and 2021 and to identify the possible determinants of regional differences in antidiabetic medication use. METHODS For this retrospective drug utilization study, yearly wholesale database was used, which provides total coverage for ambulatory antidiabetic drug sales in Hungary, including both reimbursed and non-reimbursed medications. Data were expressed as Defined Daily Dose per 1000 inhabitants per day (DDD/TID), percentage of total use and the ratio of the highest and lowest utilization values among the counties (max/min ratio). To assess the potential reasons for regional differences in antidiabetic drug use, we analyzed the associations between regional drug utilization data and possible determinants. RESULTS The total national antidiabetic medication use has increased by 7.6% and reached 94.8 DDD/TID in 2021. Regarding antidiabetic subgroups, the use of metformin and novel antidiabetics (DPP4Is, GLP1As and SGLT2Is) and their combinations increased in all counties, while sulfonylurea consumption decreased, and insulin use was stable. In 2021, 19.2-24.1% of the total antidiabetic medication consumption was novel antidiabetics, 39.1-47.2% metformin, 14.8-25.8% sulfonylureas and 23.6-30.5% were insulins. Regional differences in antidiabetic medication consumption were considerable mainly in the case of GLP1As (max/min ratio:3.00), sulfonylureas (2.03) and SGLT2Is (1.92) in 2021. The association between antidiabetic medication use and possible determinants was confirmed in the case of unemployment rate and sulfonylurea use, the number of public medical card holders per ten thousand inhabitants and human insulin and sulfonylurea use. GLP1As were the only antidiabetic drug group that did not correlate with any of the investigated factors. CONCLUSIONS Although novel antidiabetic drug use was growing dynamically in Hungary, sulfonylurea use is still considerable. Differences in antidiabetic drug consumption were substantial between the regions.

Abstract
CONTEXT VERTIS CV evaluated the cardiovascular safety of ertugliflozin in patients with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD). OBJECTIVE The aim of these analyses was to assess the insulin requirements of VERTIS CV patients over the trial duration. METHODS Patients received ertugliflozin 5 mg, 15 mg, or placebo once daily; mean follow-up was 3.5 years. Time to insulin initiation in patients who were insulin naïve at baseline, change in insulin dose in patients receiving baseline insulin, and hypoglycemia incidence in both patient groups were assessed. RESULTS In VERTIS CV, mean duration of type 2 diabetes was 13.0 years; glycated hemoglobin was 8.2%. Among 4348 (53%) insulin-naïve patients, the likelihood of insulin initiation was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: hazard ratio [HR] 0.70, 95% CI 0.58-0.84; ertugliflozin 15 mg: HR 0.64, 95% CI 0.53-0.78). Time to insulin initiation was delayed with ertugliflozin; the estimated delay in reaching a 10% cumulative incidence of new insulin initiations vs placebo was 399 days with ertugliflozin 5 mg and 669 days with ertugliflozin 15 mg. Among 3898 (47%) patients receiving baseline insulin, the likelihood of requiring a ≥20% increase in insulin dose was significantly reduced with ertugliflozin vs placebo (ertugliflozin 5 mg: HR 0.62, 95% CI 0.52-0.75; ertugliflozin 15 mg: HR 0.51, 95% CI 0.41-0.62). The incidence of hypoglycemia events was not increased with ertugliflozin treatment. CONCLUSION In VERTIS CV patients, ertugliflozin reduced the likelihood of insulin initiation, delayed the time to insulin initiation by up to ∼1.8 years, and reduced insulin dose requirements vs placebo, without increasing hypoglycemia events.

Abstract
According to the current treatment guidelines, the therapy of type 2 diabetes mellitus should follow a stepwise therapy adjustment and intensification approach as soon as blood glucose control is no longer achieved with preceding diabetes treatment. However, clinical practice shows that the recommended steps for therapy escalation are often not followed, and treatment intensification is delayed. Especially the initiation with insulin and its intensification is often considerably delayed, even though the patient has high blood glucose levels, remaining above target even for years. In addition, treatment adherence is often lower with insulin therapy than with other antidiabetic treatment. This is problematic in terms of the risks for morbidity and mortality due to microvascular and macrovascular complications. The phenomenon known as therapeutic inertia occurs mainly with chronic diseases. The reasons thereof are complex and can be related to the person with diabetes and/or the healthcare professional. Main reasons are the frequency of insulin injections and a rigid treatment regimen, which are perceived as inconvenient and restrictive. Also, the complexity of insulin treatment, the required training, and its negative image of insulin as "last option" are negatively perceived. Results from surveys show that patients and physicians would prefer injections to be administered less frequently. Experience with once-weekly glucagon-like peptide-1 receptor agonists (GLP-1-RA) has been encouraging in terms of efficacy, adherence, and patient satisfaction. Intensive research is currently being conducted on novel insulin analogues with once-weekly application.

Abstract
INTRODUCTION Resistance to initiating insulin therapy is common for people with type 2 diabetes (T2D) using multiple oral agents, resulting in sustained poor glycemic control. We explored a non-pharmacologic option and examined whether adults with T2D and elevated hemoglobin A1c (HbA1c) who were using multiple, non-insulin antihyperglycemics could obtain glycemic benefit from limited, episodic use of real-time continuous glucose monitoring (rtCGM). METHODS A randomized, pilot trial enrolled patients with T2D who were using two or more non-insulin therapies and had HbA1c values of 7.8-10.5%. Following a baseline, 10-day, blinded CGM session, participants were randomized 2:1, rtCGM or self-monitoring of blood glucose (SMBG). Medication changes were not made during the 12-week study unless required for safety; benefits would result from lifestyle changes. The rtCGM group used unblinded rtCGM for three sessions at weeks 0, 4, and 8, and the control group managed diabetes with SMBG and wore blinded rtCGM at week 8. Glycemic endpoints were assessed. RESULTS Seventy participants were enrolled from eight North American sites and data were available from 68 (n = 45 rtCGM; n = 23 SMBG). Median (IQR) baseline HbA1c was 8.4 (0.8)% and 8.3 (1.2)% and median (IQR) change in HbA1c at week 12 was - 0.5 (1.3)% and - 0.2 (1.1)% for the rtCGM and SMBG groups, respectively (between-group difference p = 0.74). More than one-third (34.1%) of the rtCGM group vs 17.4% of the SMBG group reached the HbA1c goal of less than 7.5% at week 12 (between-group difference p = 0.12). Compared to run-in, mean (SD) time in range (TIR 70-180 mg/dL) at week 8 increased for the rtCGM group (56.3 [24.5]% vs 63.1 [25.5]%) while it decreased for the SMBG group (68.4 [21.5]% vs 55.1 [30.3]%). HbA1c reductions were not sustained at month 9. CONCLUSION In this pilot study, limited episodic rtCGM use in people failing multiple non-insulin therapies resulted in modest, short-term glycemic benefits.

Abstract
BACKGROUND Drug therapy for diabetes mellitus (DM) has had a significant impact on quality of life and work potential of affected persons and has contributed to a remarkable decrease in the frequency and severity of complications, hospitalizations, and mortality. The current approach is the result of incremental progress in using technological advances to increase the safety and effectiveness of insulin therapy and the introduction of new molecules as oral and injectable antidiabetic drugs. STUDY QUESTION What are the milestones of the changes in the expert approach to the pharmacological management of DM in the past century? STUDY DESIGN To determine the changes in the experts' approach to the management of DM, as presented in a widely used textbook in the United States. DATA SOURCES The chapters on describing the management of DM in the 26 editions of Cecil Textbook of Medicine published from 1927 to 2020. RESULTS In 1927, DM was treated with insulin extracted from the pancreas of large animals (cattle, hogs, and sheep) and purified with alcohol to prevent the tissues' proteolytic action on the hormone. The therapeutic milestones in DM marked 2 avenues for innovation. The first created advances in insulin therapy, starting with processes that led to the production of crystalline insulin and protamine zinc insulin (1937), synthetic human insulin (1996), and prandial (2000) and basal (2004) insulin analogues. The second was an effort to develop and introduce in clinical practice in the United States oral antidiabetic drugs, starting with tolbutamide, a sulfonylurea (1955), followed by metformin, a biguanide (1996), thiazolidinediones, alpha-glucosidase inhibitors, and benzoic acid derivatives (2000), dipeptidyl peptidase-4 inhibitors and glucagon-like peptide 1 receptor agonists (2008), and sodium glucose cotransporter 2 inhibitors (2020). A latent period of 40 years between significant advances was likely because of searches for new technologies (eg, recombinant DNA for the production of synthetic insulin and analogues) and, at least in part, to the impact of the controversial University Group Diabetes Project on the development and acceptance of oral antidiabetic drugs. CONCLUSIONS The pharmacological management of DM has progressed unevenly, with a long latency period in the second half of the last century followed by highly encouraging advances in the first 2 decades of the 21st century. In chronological order, the major advances were synthetic insulins obtained through DNA recombinant technology, adoption of metformin as first line therapy, and introduction of antidiabetic medication classes that also promote weight reduction and cardiovascular health.
