Cardiovascular and mortality outcomes of DPP-4 inhibitors vs. sulfonylureas as metformin add-on therapy in patients with type 2 diabetes: A systematic review and meta-analysis. PLoS One 2025; 20:e0321032. [PMID: 40323973 DOI: 10.1371/journal.pone.0321032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2024] [Accepted: 02/26/2025] [Indexed: 05/07/2025] Open
Abstract
BACKGROUND Type 2 diabetes significantly increase the risk of cardiovascular disease and mortality. This systematic review and meta-analysis compared cardiovascular and mortality outcomes in type 2 diabetes patients receiving dipeptidyl peptidase-4 inhibitors (DPP-4is) plus metformin versus sulfonylureas (SUs) plus metformin as add-on therapy. METHODS PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase, Google Scholar, and Scopus were searched through January 1, 2025, for studies comparing DPP-4is plus metformin versus SUs plus metformin in type 2 diabetes patients. Outcomes of interest were major adverse cardiovascular events and all-cause mortality. Heterogeneity was assessed using Cochran's Q test and I2 statistic. Publication bias was evaluated with Begg's and Egger's tests. Study quality was assessed with the Jadad scale (for randomized controlled trials) and the Newcastle-Ottawa Scale (for observational studies). RESULTS Twenty-seven studies (2012-2024), encompassing 1,505,821 participants, were included in the analysis. Major adverse cardiovascular events were reported in 21 studies, and all-cause mortality data were available from 19 studies. Meta-analysis revealed a significantly lower risk of both major adverse cardiovascular events (risk ratio [RR]: 0.79; 95% confidence interval [CI]: 0.73-0.84; p < 0.001) and all-cause mortality (RR: 0.79; 95% CI: 0.71-0.88; p < 0.001) in patients with diabetes treated with DPP-4 inhibitors plus metformin compared to those treated with SUs plus metformin. No publication bias was detected. CONCLUSION In type 2 diabetes patients treated with metformin, adding a DPP-4is is associated with significantly lower risks of major adverse cardiovascular events and all-cause mortality compared to adding an SUs. These findings underscore the potential cardiovascular benefits of DPP-4is and their role in improving patient outcomes.

Abstract
BACKGROUND This study aims to conduct a systematic review and meta-analysis of the currently present literature analyzing the effectiveness and safety profile of prusogliptin, a novel dipeptidyl peptidase-IV (DPP-4) inhibitor, as compared to placebo in type 2 diabetes mellitus (T2DM) patients. METHODS This systemic review and meta-analysis complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search strategy based on various MeSH terms was run on: PubMed/Medline, SCOPUS, and Cochrane Central, which were then systematically searched from inception till March 2024 to select all relevant Randomized Control Trials (RCT). RESULTS The analysis of the findings from three RCTs with 957 patients revealed that prusogliptin reduced Hemoglobin A1c (HbA1c)% levels in T2DM patients significantly [Mean Difference (MD): -0.62, 95% Confidence Interval (CI): -0.74 to -0.50, I2 = 0%, p < 0.001] and led to more patients with a HbA1c% ≤ 7% [Odds Ratio (OR): 2.65, 95%CI: 1.94 to 3.61, I2 = 0%, p < 0.00001]. However, prusogliptin led to a non-significant increase in weight when compared with placebo (MD: 0.22, 95% CI: -0.50 to 0.93, I2 = 60%, p = 0.551). The safety profile of prusogliptin revealed a non-significant decrease in treatment-emergent adverse events (OR: 0.90, 95% CI: 0.59 to 1.38, I2 = 43%, p = 0.64) and a non-significant increase in treatment-emergent serious adverse events (OR: 1.02, 95% CI: 0.43 to 2.44, I2 = 0%, p = 0.96) and drug-related adverse events (OR: 1.07, 95%CI: 0.68 to 1.69, I2 = 0%, p = 0.76). CONCLUSION Prusogliptin has a favorable efficacy in attaining glycemic control in patients with T2DM. However, its safety profile yields uncertain outcomes. More literature is required for a definitive result.

Abstract
Objectives The therapeutic efficacy of Traditional Chinese Medicine (TCM) in modulating gut microbiota for diabetes treatment has garnered increasing scholarly attention. This study aims to meticulously examine current research trajectories and focal areas from 2004 to 2024, providing a foundational framework for future inquiries. Methods A comprehensive search of documents published between 2004 and 2024 was conducted using the Web of Science database. The resulting data were analyzed and visualized using R software, VOSviewer, and CiteSpace. Results The study included a total of 751 documents. From 2004 to 2022, the number of annual publications showed a continuous upward trend (2004: n = 1 to 2022: n = 159), and the number of publications in 2023 (n = 141) decreased slightly from the previous year. China emerged as the leading country in terms of article publications (n = 430). Additionally, the United States played a prominent role in international research collaborations. Frontiers in Pharmacology (n = 31) was the most frequently published journal, while Nature (n = 1,147) achieved the highest citation count. Key identified keywords included obesity, insulin resistance, inflammation, and oxidative stress. Conclusion Three key research focuses in this domain include: the therapeutic effects of active constituents in TCM on diabetes via gut microbiota modulation, the underlying mechanisms through which TCM influences gut microbiota in diabetes management, and the targeted regulation of specific gut bacterial populations by TCM in the treatment of diabetes.

Abstract
INTRODUCTION Type 2 Diabetes Mellitus (T2DM) accounts for more than 95% of all diabetes cases and is a leading cause of disability and death. This study aimed to evaluate the effectiveness and safety of a combination therapy involving metformin, teneligliptin, and glimepiride in patients diagnosed with T2DM. METHODS The present quasi-experimental clinical trial involved 300 adult T2DM patients. They were divided into three groups: Group 1 (Metformin; n=100), Group 2 (Metformin + Teneligliptin; n=100), and Group 3 (Metformin + Teneligliptin +; n=100). Along with demographic data, we collected information on HbA1c, FBS, and PPBS levels, as well as fasting insulin, CPeptide, HOMA-IR, QUICKI-IR, and lipid, renal, and hepatic profiles at baseline and after 3, 6, and 12 months. Data analysis was performed using SPSS 21.0 software. RESULTS A total of 300 patients participated in the study. At the end of 12 months, triple-drug therapy achieved significant glycemic control (HbA1c: 6.56±0.50%; P<0.0001) and reduced FBS (7.6±1.41 mg/dl; P<0.0001), PPBS (9.39±2.14 mg/dl; P<0.0001), and fasting insulin (11.26±2.5 IU; P<0.0001), C-peptide (2.01±2.29 ng/ml; P<0.0001), and insulin resistance by HOMA-IR (3.74±0.7; P<0.0001). Favorable lipid profiles (P<0.0001) were noted versus other groups. Despite renal and hepatic profile variations, values remained within the normal range. CONCLUSION The combination of teneligliptin with metformin and glimepiride in T2DM patients demonstrated significant improvements in glycaemic control, reduced insulin resistance, and positive effects on lipid, renal, and hepatic profiles. Importantly, the therapy did not result in serious adverse drug reactions, such as hypoglycemia. We need more RCTs to substantiate these findings.

Abstract
Background The escalating global economic burden of ischemic stroke poses a significant public health challenge amid global aging trends. The broad therapeutic efficacy of new antidiabetic drugs may offer new options in the prevention and treatment of ischemic stroke. Consistent conclusions regarding the relationship between novel antidiabetic agents and the risk of ischemic stroke remain elusive, and the causal relationship deserves further investigation. Materials and methods Three novel antidiabetic drug targets were selected, and cis-expression quantitative trait loci (cis-eQTL) were screened as instrumental variables. Genetic association data for ischemic stroke were obtained from the Genome-wide Association Study (GWAS) database. Mendelian randomization (MR) analysis, facilitated by R software, calculated MR estimates for each single nucleotide polymorphism (SNP), and meta-analysis was performed using five methods. To ensure robustness, sensitivity analyses, heterogeneity analyses, horizontal pleiotropy analyses, and co-localization analyses were conducted for significant MR associations. Results Three eQTLs for antidiabetic drug genes served as instrumental variables, utilizing a GWAS dataset comprising 34,217 cases and 406,111 controls for ischemic stroke. Genetic variants in glucagon-like peptide-1 receptor agonists (GLP-1 RA) targets exhibited a positive correlation with ischemic stroke risk (OR 1.06, 95% CI 1.04-1.08, P = 0.000), while genetic variation in dipeptidyl peptidase 4 inhibitors (DPP-4i) targets showed a negative association with ischemic stroke risk (OR 0.93, 95% CI 0.89-0.97, P = 0.003). Sensitivity analyses supported robust conclusions, revealing no heterogeneity or horizontal pleiotropy. Conclusion This study found that GLP-1 RA and DPP-4i were associated with an increased risk of ischemic stroke by MR analysis. Although sensitivity analyses provide support for this result, it contradicts previous knowledge. Therefore, the results of this study still need to treated with caution. Updated and more in-depth GWAS data and high-quality real-world data are expected to validate the results.

Abstract
Objective Several oral antidiabetic regimens are available for treating type 2 diabetes mellitus (T2DM), dipeptidyl peptidase-4 inhibitors (DPP4i) being one of them. We conducted a network meta-analysis (NMA) comparing DPP4i plus metformin (Met) combination with other Met-based oral antidiabetic drug (OAD) combinations used in treating patients with T2DM. Methods We searched PubMed and Embase from inception until 19th April, 2022 for phase II and phase III trials in patients with T2DM on Met-based traditional OADs. The primary outcome was assessed by change in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2-hour post-prandial blood glucose (2h-PPG). The secondary safety outcomes assessed were hypoglycemic events, serious adverse events (SAEs), cardiovascular (CV) events, and gastrointestinal (GI) events. Results Sixty-two trials were included in the analysis. The combination of DPP4i + Met revealed a comparable mean reduction in HbA1c levels to the glinides (Gli) + Met combination (mean difference [MD]: -0.03%, 95% CI: 0.69, -0.65), although the difference was not statistically significant. The mean HbA1c reduction with DPP4i + Met was greater than with sulfonylureas (SU) + Met (MD: -0.05, 95% CI: -0.29, 0.39), thiazolidinedione (TZD) + Met (MD: -0.69, 95% CI: -1.39, -0.02), and SU + TZD (MD: 0.21; 95% CI: -1.30, 1.71), with no statistical significance. DPP4i + Met demonstrated a non-significant lower incidence of CV events in comparison to TZD + Met (RR: 1.01, 95% CI: 0.46, 2.45) and SU + Met (RR: 1.06, 95% CI: 0.61, 2.06). Conclusion DPP4i in combination with Met was efficacious and had a well-tolerated safety profile compared with other traditional OADs. This combination can be considered as a suitable treatment option for patients with T2DM.

Abstract
OBJECTIVE To assess the safety of sitagliptin added to metformin on cardiovascular adverse events in real world patients with type 2 diabetes mellitus (T2DM). METHODS Real world data from Yinzhou Regional Health Care Database were used to select T2DM patients with diagnosis and treatment records in the platform from January 1, 2017 to December 31, 2022. According to drug prescription records, the patients were divided into metformin plus sitagliptin group (combination group) and metformin monotherapy group(monotherapy group). A series of retrospective cohorts were constructed according to the index date.Finally, full retrospective cohorts were constructed according to propensity score model, including baseline covariates that might be related to outcomes, to match the subjects in the combination group and monotherapy group for the purpose of increasing the comparability of baseline characteristics. The participants were followed up from the index date until the first occurrence of the following events: Diagnosis of outcomes, death, or the end of the study period (December 31, 2022). Cox proportional risk model was used to estimate the hazard ratio(HR)and 95% confidence interval (CI) of sitagliptin added to metformin on 3-point major adverse cardiovascular events (3P-MACE) combination outcome and secondary cardiovascular outcomes. RESULTS Before propensity score matching, the proportion of the patients in combination group using insulin, α glucosidase inhibitors, sodium-glucose transporter 2 inhibitors (SGLT-2I) and glienides at baseline was higher than that in monotherapy group, and the baseline fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels in combination group were higher than those in monotherapy group. After propensity score matching, 5 416 subjects were included in the combination group and the monotherapy group, and baseline characteristics were effectively balanced between the groups. The incidence densities of 3P-MACE were 6.41/100 person years and 6.35/100 person years, respectively. Sitagliptin added to metformin did not increase or decrease the risk of 3P-MACE compared with the metformin monotherapy (HR=1.00, 95% CI: 0.91-1.10). In secondary outcomes analysis, the incidence of cardiovascular death was lower in the combination group than in the monotherapy group (HR=0.59, 95% CI: 0.41-0.85), and no association was found between sitagliptin and the risk of myocardial infarction and stroke (HR=1.12, 95% CI: 0.89-1.41; HR=0.99, 95% CI: 0.91-1.12). CONCLUSION In T2DM patients in Yinzhou district of Ningbo, compared with metformin alone, sitagliptin added to metformin may reduce the risk of cardiovascular death, and do not increase the incidence of overall cardiovascular events. The results of this study can provide real-world evidence for post-marketing cardiovascular safety evaluation of sitagliptin.

Abstract
Uses of real-world data in drug safety and effectiveness studies are often challenged by various sources of bias. We undertook a systematic search of the published literature through September 2020 to evaluate the state of use and utility of negative controls to address bias in pharmacoepidemiologic studies. Two reviewers independently evaluated study eligibility and abstracted data. Our search identified 184 eligible studies for inclusion. Cohort studies (115, 63%) and administrative data (114, 62%) were, respectively, the most common study design and data type used. Most studies used negative control outcomes (91, 50%), and for most studies the target source of bias was unmeasured confounding (93, 51%). We identified 4 utility domains of negative controls: 1) bias detection (149, 81%), 2) bias correction (16, 9%), 3) P-value calibration (8, 4%), and 4) performance assessment of different methods used in drug safety studies (31, 17%). The most popular methodologies used were the 95% confidence interval and P-value calibration. In addition, we identified 2 reference sets with structured steps to check the causality assumption of the negative control. While negative controls are powerful tools in bias detection, we found many studies lacked checking the underlying assumptions. This article is part of a Special Collection on Pharmacoepidemiology.

Effect of Dipeptidyl Peptidase-4 Inhibitors vs. Metformin on Major Cardiovascular Events Using Spontaneous Reporting System and Real-World Database Study. J Clin Med 2022; 11:jcm11174988. [PMID: 36078917 PMCID: PMC9456525 DOI: 10.3390/jcm11174988] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 08/22/2022] [Accepted: 08/23/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Metformin had been recommended as the first-line treatment for type 2 diabetes since 2006 because of its low cost, high efficacy, and potential to reduce cardiovascular events, and thus death. However, dipeptidyl peptidase-4 (DPP-4) inhibitors are the most commonly prescribed first-line agents for patients with type 2 diabetes in Japan. Therefore, it is necessary to clarify the effect of DPP-4 inhibitors on preventing cardiovascular events, taking into consideration the actual prescription of antidiabetic drugs in Japan. Methods: This study examined the effect of DPP-4 inhibitors on preventing cardiovascular events. The Japanese Adverse Drug Event Report (JADER) database, a spontaneous reporting system in Japan, and the Japanese Medical Data Center (JMDC) Claims Database, a Japanese health insurance claims and medical checkup database, were used for the analysis. Metformin was used as the DPP-4 inhibitor comparator. Major cardiovascular events were set as the primary endpoint. Results: In the analysis using the JADER database, a signal of major cardiovascular events was detected with DPP-4 inhibitors (IC: 0.22, 95% confidence interval: 0.03–0.40) but not with metformin. In the analysis using the JMDC Claims Database, the hazard ratio of major cardiovascular events for DPP-4 inhibitors versus metformin was 1.01 (95% CI: 0.84–1.20). Conclusions: A comprehensive analysis using two different databases in Japan, the JADER and the JMDC Claims Database, showed that DPP-4 inhibitors, which are widely used in Japan, have a non-inferior risk of cardiovascular events compared to metformin, which is used as the first-line drug in the United States and Europe.

Abstract
The management of diabetes in cirrhosis and liver transplantation can be challenging. There is difficulty in diagnosis and monitoring of diabetes as fasting blood sugar values are low and glycosylated hemoglobin may not be a reliable marker. The challenges in the management of diabetes in cirrhosis include the likelihood of cognitive impairment, risk of hypoglycemia, altered drug metabolism, frequent renal dysfunction, risk of lactic acidosis, and associated malnutrition and sarcopenia. Moreover, calorie restriction and an attempt to lose weight in obese diabetics may be associated with a worsening of sarcopenia. Many commonly used antidiabetic drugs may be unsafe or be associated with a high risk of hypoglycemia in cirrhotics. Post-transplant diabetes is common and may be contributed by immunosuppressive medication. There is inadequate clinical data on the use of antidiabetic drugs in cirrhosis, and the management of diabetes in cirrhosis is hampered by the lack of guidelines focusing on this issue. The current review aims at addressing the practical management of diabetes by a hepatologist.

BMJ Open Diabetes Res Care 2021; 9:9/2/e002352. [PMID: 34969692 PMCID: PMC8718392 DOI: 10.1136/bmjdrc-2021-002352] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 11/26/2021] [Indexed: 12/21/2022] Open
Abstract
INTRODUCTION Metformin is the initial oral antihyperglycemic agent (OHA) of choice for most patients with type 2 diabetes (T2D). However, more than one agent is often required for optimal glucose control. As the choice of preferred second OHAs is less well defined, we sought to compare the real-world safety of sulfonylureas to other OHAs as add-on therapy to metformin in patients with T2D. RESEARCH DESIGN AND METHODS This retrospective cohort study included adults in Manitoba, Canada with T2D from 2006 to 2017. Using a new-user design, we divided patients who started on metformin into two groups: add-on therapy with a sulfonylurea and add-on therapy with a different OHA. Outcomes included all-cause mortality, cardiovascular events, and major hypoglycemic episodes. We calculated propensity scores and applied inverse probability of treatment weights to each individual. We compared groups using Cox proportional hazards regression and explored differences in HRs between pre-2008 (acarbose, meglitinides, and thiazolidinediones) and post-2008 (dipeptidyl peptidase-4 inhibitors, glucagon-like peptide-1 receptor agonists, and sodium-glucose linked transporter-2 inhibitors) OHAs. RESULTS Our cohort included 32 576 individuals (28 077 metformin plus sulfonylurea and 4499 metformin plus 'other'). Patients newly prescribed a sulfonylurea in the setting of metformin had a higher risk of all-cause mortality (HR 1.44, 95% CI 1.12 to 1.84, p=0.005) and major hypoglycemic episodes (HR 2.78, 95% CI 1.66 to 4.66, p<0.001) than those prescribed an 'other' OHA. No differences in cardiovascular events were observed (HR 0.99, 95% CI 0.81 to 1.22, p=0.92). In subgroup analyses, mortality and cardiovascular event risk was higher in patients prescribed sulfonylureas versus post-2008 OHAs. CONCLUSIONS Sulfonylureas as add-on therapy to metformin are associated with increased risk of all-cause mortality and major hypoglycemic episodes compared with 'other' OHAs. Post hoc analysis suggests newer OHAs may be preferred to sulfonylureas as second-line therapy for glycemic control.

Cardioprotective effects of dipeptidyl peptidase-4 inhibitors versus sulfonylureas in addition to metformin: A nationwide cohort study of patients with type 2 diabetes. DIABETES & METABOLISM 2021; 48:101299. [PMID: 34728339 DOI: 10.1016/j.diabet.2021.101299] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 10/04/2021] [Accepted: 10/14/2021] [Indexed: 01/14/2023]
Abstract
AIMS Cardiovascular effects of dipeptidyl peptidase-4 inhibitors (DPP4i) versus sulfonylureas (SU) remain controversial in observational studies. This study aimed to evaluate the influence of DPP4i on major adverse cardiovascular events (MACEs), including acute myocardial infarction, cerebrovascular disease, heart failure, cardiogenic shock, malignant dysrhythmia, and revascularisation. MATERIALS AND METHODS We conducted a nationwide cohort study using claims data from the National Health Insurance in Taiwan from 2007 to 2013. We enrolled type 2 diabetes patients who received DPP4i or SU in addition to metformin. DPP4i users were matched to SU users using propensity scores at a ratio of 1:1. The study outcomes were hospitalisation for MACE, heart failure, acute myocardial infarction, cerebrovascular disease, coronary revascularisation, and hypoglycaemia. RESULTS There were 37,317 matched pairs of DPP4i and SU users with a mean follow-up of 2.1 years. Compared with SU users, DPP4i users showed a significantly lower risk of hospitalisation for MACE (HR 0.79 [95% CI 0.75-0.82]), heart failure (0.86 [0.79-0.93]), acute myocardial infarction (0.76 [0.68-0.92]), and cerebrovascular disease (0.72 [0.67-0.77]). Both sitagliptin (0.89 [0.85-0.94]) and vildagliptin ([0.77 [0.60-0.99]) showed a significantly lower risk of hospitalisation for MACE, but saxagliptin showed a borderline significantly higher risk of hospitalisation for heart failure (1.59 [1.00-2.55]). CONCLUSIONS DPP4i showed better cardioprotective effects than SU, especially among patients receiving sitagliptin or vildagliptin.

Abstract
Dipeptidyl peptidase-4 inhibitors (DPP-4is) and sodium-glucose cotransporter type 2 inhibitors (SGLT2is) offer new options for the oral management of type 2 diabetes mellitus (T2DM), with the advantage in the elderly population to be devoid of a high risk of hypoglycaemia. SGLT2is have also shown benefits regarding cardiovascular (heart failure) and renal protection, including in patients with T2DM aged ≥ 65 years while DPP-4is have only proved cardiovascular and renal safety without superiority compared with placebo. The glucose-lowering efficacy of the two pharmacological classes is almost similar including in older patients with T2DM. However, the tolerance and safety profile may be highly different and overall more favourable with DPP-4is than with SGLT2is. Some adverse events have been reported with SGLT2is which may be more prevalent or severe in older patients than in younger patients. The present comprehensive review focuses on the benefit/risk balance in the elderly population with T2DM by comparing the profile of DPP-4is and SGLT2is regarding the following potential issues: metabolic disorders (hypoglycaemia and diabetic ketoacidosis); cardiac and vascular issues (atheromatous cardiovascular disease, heart failure, volume reduction hypotension, and lower limb amputations); renal endpoints including acute renal injury; risk of infections; digestive disorders; bone and skin adverse events; and cancer risk. Both DPP-4is and SGLT2is have their own advantages and disadvantages. Personalised treatment is recommended based upon the efficacy/safety profile of each drug class and individual patient characteristics that may be markedly different among the heterogeneous population of older individuals with T2DM.

Abstract
Influenza vaccine effectively reduced risks for in-hospital death or hospitalization, regardless of statin use. Debates on whether statin use reduces the effectiveness of influenza vaccines against critical illness and death among persons >65 years of age continue. We conducted a study of 9,427,392 persons >65 years of age who did and did not receive influenza vaccinations during 12 consecutive influenza seasons, 2000–01 through 2011–12. Using data from Taiwan’s National Health Insurance Research Database, we performed propensity score-matching to compare vaccinated persons with unvaccinated controls. After propensity score-matching, the vaccinated group had lower risks for in-hospital death from influenza and pneumonia and for hospitalization for pneumonia and influenza, circulatory conditions, and critical illnesses compared with the unvaccinated group. We stratified the 2 groups by statin use and analyzed data by interaction analysis and saw no statistically significant difference. We found that influenza vaccine effectively reduced risks for hospitalization and death in persons >65 years of age, regardless of statin use.

Abstract
Diabetes is a very important comorbidity in patients with heart failure. When both diseases coexist cardiovascular morbidity and mortality is greatly increased. Therefore, it is of clinical importance to treat both diseases as early as possible with an optimal therapy. Hitherto, heart failure therapy did not differ if a patient had concomitant diabetes. However, with SGLT-2 inhibitors having demonstrated to reduce hospitalization of heart failure independent of diabetes state and expected to be included into the ESC heart failure treatment guidelines in 2021 coexisting diabetes potentially will make a difference when to start therapy. In this article we provide an overview of current recommendations and also provide clinical considerations for the therapy of heart failure with concomitant diabetes.

Abstract
AIM To assess whether the use of evogliptin, a novel dipeptidyl peptidase-4 inhibitor (DPP-4i), was associated with an increased risk of cardiovascular events compared with glimepiride in patients with type 2 diabetes (T2D). METHODS We conducted a population-based cohort study using South Korea's nationwide healthcare database from 1 January 2014 to 31 December 2018. We identified a base cohort of patients with T2D who newly initiated metformin monotherapy, from which we identified a study cohort of patients who either added or switched to glimepiride or DPP-4is (including evogliptin). Patients were followed up from initiation of DPP-4is or glimepiride until the earliest of either outcome occurrence or 31 December 2018. Our primary outcome was hospitalization or an emergency visit for cardiovascular events, a composite endpoint comprised of cerebrovascular events, heart failure, myocardial infarction, transient ischaemic attack, angina pectoris and revascularization procedures; secondary outcomes were the individual components of the primary outcome. A multivariable Cox proportional hazards model was used to estimate adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) for the risk of study outcomes associated with evogliptin compared with glimepiride. RESULTS Our base and study cohorts had 317,307 and 128,788 patients, respectively, of which 100,038 were DPP-4i users (2946 were evogliptin users) and 28,750 were glimepiride users within the study cohort. The median follow-up was 195 days for evogliptin and 113 days for glimepiride users. Compared with glimepiride, evogliptin was associated with a reduced risk of the primary outcome (aHR 0.67, 95% CI 0.48-0.95) and cerebrovascular events (aHR 0.41, 95% CI 0.22-0.78) but showed non-significant associations for myocardial infarction (aHR 0.63, 95% CI 0.27-1.46), heart failure (aHR 0.35, 95% CI 0.09-1.47), transient ischaemic attack (aHR 0.23, 95% CI 0.03-1.72) and angina pectoris (aHR 1.35, 95% CI 0.82-2.21). CONCLUSIONS Findings from this population-based cohort study provide novel real-world evidence that the use of evogliptin, compared with glimepiride, did not increase the risk of cardiovascular events, including cerebrovascular events, myocardial infarction, heart failure, transient ischaemic attack and angina pectoris.

Abstract
This study assessed the effects of dipeptidyl peptidase-4 inhibitors (DPP4is) vs. sulfonylureas (SUs) on composite renal, cardiovascular, and hospitalized hypoglycemia outcomes in type 2 diabetes (T2D) patients with advanced chronic kidney disease (CKD) who were underrepresented in previous clinical studies. The National Health Insurance Research Database was utilized. Patients with T2D and advanced CKD (stages 3b-5) with stable use of DPP4is or SUs were identified during 2011-2015 and followed until death or December 31, 2016. The primary outcome was the composite renal outcome. Secondary outcomes included hospitalized heart failure (HHF), major adverse cardiovascular event (MACE), hospitalized hypoglycemia, and all-cause death. Subdistribution hazard models were employed to assess treatment effects on clinical outcomes. A total of 1,204 matched pairs of DPP4i and SU users were analyzed. Compared with SUs, DPP4is had no significant difference in the risks of the composite renal outcome, HHF, and three-point and four-point MACE (hazard ratios (95% confidence intervals): 1.10 (0.93-1.31), 1.11 (0.95-1.30), 0.97 (0.79-1.19), and 1.08 (0.94-1.24), respectively), but reduced risks of hospitalized hypoglycemia (0.53 (0.43-0.64)) and all-cause death (0.71 (0.53-0.96)). In conclusion, among patients with T2D and advanced CKD, the use of DPP4is vs. SUs was associated with comparable safety profiles on renal and cardiovascular outcomes, and reduced risks of hospitalized hypoglycemia and all-cause death. DPP4is may be preferred for patients with T2D and advanced CKD, and the regular monitoring on cardiac function remains crucial among this population who are at a higher risk of HHF.

Abstract
BACKGROUND Oral semaglutide was approved in 2019 for blood glucose control in patients with type 2 diabetes mellitus (T2DM) and was the first oral glucagon-like peptide 1 receptor agonist (GLP-1 RA). T2DM is associated with substantial healthcare expenditures in the US, so the cost of a new intervention should be weighed against clinical benefits. OBJECTIVE This study evaluated the budget impact of a treatment pathway with oral semaglutide 14 mg daily versus oral sitagliptin 100 mg daily among patients not achieving target glycated hemoglobin (HbA1c) level despite treatment with metformin. METHODS This study used the validated IQVIA™ CORE Diabetes Model to simulate the treatment impact of oral semaglutide 14 mg and sitagliptin 100 mg over a 5-year time horizon from a US healthcare sector (payer) perspective. Trial data (PIONEER 3) informed cohort characteristics and treatment effects, and literature sources informed event costs. Population and market share data were from the literature and data on file. The analysis evaluated the estimated budget impact of oral semaglutide 14 mg use for patients currently using sitagliptin 100 mg considering both direct medical and treatment costs to understand the impact on total cost of care, given underlying treatment performance and impact on avoidable events. RESULTS In a hypothetical plan of 1 million lives, an estimated 1993 patients were treated with sitagliptin 100 mg in the target population. Following these patients over 5 years, the incremental direct medical and treatment costs of a patient using oral semaglutide 14 mg versus sitagliptin 100 mg was $US16,562, a 70.7% increase (year 2019 values). A hypothetical payer would spend an additional $US3,300,143 (7.1%) over 5 years for every 10% of market share that oral semaglutide 14 mg takes away from sitagliptin 100 mg. Univariate and scenario analyses with alternate inputs and assumptions demonstrated consistent results. CONCLUSIONS Use of oral semaglutide 14 mg in patients currently receiving sitagliptin 100 mg substantially increases the budget impact for patients with T2DM whose blood glucose level is not controlled with metformin over a 5-year time horizon for US healthcare payers.

Long-term safety and efficacy of alogliptin, a DPP-4 inhibitor, in patients with type 2 diabetes: a 3-year prospective, controlled, observational study (J-BRAND Registry). BMJ Open Diabetes Res Care 2021; 9:9/1/e001787. [PMID: 33441417 PMCID: PMC7812112 DOI: 10.1136/bmjdrc-2020-001787] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 11/15/2020] [Accepted: 12/05/2020] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION Given an increasing use of dipeptidyl peptidase-4 (DPP-4) inhibitors to treat patients with type 2 diabetes mellitus in the real-world setting, we conducted a prospective observational study (Japan-based Clinical Research Network for Diabetes Registry: J-BRAND Registry) to elucidate the safety and efficacy profile of long-term usage of alogliptin. RESEARCH DESIGN AND METHODS We registered 5969 patients from April 2012 through September 2014, who started receiving alogliptin (group A) or other classes of oral hypoglycemic agents (OHAs; group B), and were followed for 3 years at 239 sites nationwide. Safety was the primary outcome. Symptomatic hypoglycemia, pancreatitis, skin disorders of non-extrinsic origin, severe infections, and cancer were collected as major adverse events (AEs). Efficacy assessment was the secondary outcome and included changes in hemoglobin A1c (HbA1c), fasting blood glucose, fasting insulin and urinary albumin. RESULTS Of the registered, 5150 (group A: 3395 and group B: 1755) and 5096 (3358 and 1738) were included for safety and efficacy analysis, respectively. Group A patients mostly (>90%) continued to use alogliptin. In group B, biguanides were the primary agents, while DPP-4 inhibitors were added in up to ~36% of patients. The overall incidence of AEs was similar between the two groups (42.7% vs 42.2%). Kaplan-Meier analysis revealed the incidence of cancer was significantly higher in group A than in group B (7.4% vs 4.8%, p=0.040), while no significant incidence difference was observed in the individual cancer. Multivariate Cox regression analysis revealed that the imbalanced patient distribution (more elderly patients in group A than in group B), but not alogliptin usage per se, contributed to cancer development. The incidence of other major AE categories was with no between-group difference. Between-group difference was not detected, either, in the incidence of microvascular and macrovascular complications. HbA1c and fasting glucose decreased significantly at the 0.5-year visit and nearly plateaued thereafter in both groups. CONCLUSIONS Alogliptin as a representative of DPP-4 inhibitors was safe and durably efficacious when used alone or with other OHAs for patients with type 2 diabetes in the real world setting.

A prospective cohort study on effects of gemigliptin on cardiovascular outcomes in patients with type 2 diabetes (OPTIMUS study). Sci Rep 2020; 10:19033. [PMID: 33149182 PMCID: PMC7642439 DOI: 10.1038/s41598-020-75594-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Accepted: 09/25/2020] [Indexed: 12/04/2022] Open
Abstract
This study was performed to evaluate the long-term cardiovascular safety of gemigliptin in patients with type 2 diabetes mellitus (T2DM). After screening, eligible patients with T2DM were enrolled, received gemigliptin, and were followed up for a median of 2.50 years. The primary outcome was a composite of confirmed cardiovascular death, nonfatal myocardial infarction, or nonfatal ischemic stroke (3-point major adverse cardiovascular event [MACE]). The key secondary outcomes were incidence of all-cause mortality and any other cardiovascular events. A total of 5179 patients were included in the study and 5113 were treated with gemigliptin. Overall, the primary outcome occurred in 26 patients within 12 months (estimated incidence by Cox proportional hazard model 0.49%, 95% CI 0.29–0.69%) and in 54 patients within 54 months (estimated incidence from Cox proportional hazard model 1.35%, 95% CI 0.92–1.77%). During the study period, the incidence rates of each component of the primary composite outcome were 0.04% (0.2 events per 1000 person-years) for cardiovascular death, 0.51% (2.2 events per 1000 person-years) for nonfatal myocardial infarction, and 0.61% (2.5 events per 1000 person-years) for nonfatal ischemic stroke. The incidence of all-cause mortality was 0.82% (3.2 events per 1000 person-years) and the incidences of other cardiovascular events were all less than 0.3%. In conclusion, T2DM patients who received gemigliptin exhibited a low incidence of the primary composite MACE and all-cause mortality. Therefore, the use of gemigliptin is expected to be safe without an increase in cardiovascular risk. Trial registration: The study was registered at ClinicalTrials.gov (identifier: NCT02290301).

Abstract
This study explored heterogeneous treatment effects (HTEs) of the real-world use of dipeptidyl peptidase-4 inhibitors (DPP-4is) vs. sulfonylureas (SUs) on cardiovascular diseases (CVDs) and mortality in patients with type 2 diabetes. Utilizing Taiwan's National Health Insurance Research Database, 19,853 propensity score-matched pairs of DPP-4i and SU stable users were identified. Classification and regression tree analyses and Cox models were applied to explore HTEs, according to various patient characteristics, on the composite CVDs, three-point major adverse cardiovascular event (MACE), and all-cause mortality. The absolute risk difference (ARD), hazard ratio (HR), and 95% confidence interval (CI) were estimated for comparing treatment effects. CVD history, ischemic stroke, or transient ischemic attack (IS/TIA) history, and age at treatment initiation were significant treatment effect modifiers. Patients with prior IS/TIA but without any other prior CVDs benefited most in reduced risks of composite CVDs from using DPP-4i vs. SU (ARD -4.31%, 95% CI -7.48% to -1.14%, HR 0.81, 95% CI 0.69 ~ 0.95), followed by those without prior IS/TIA and CVDs and initiated with DPP-4i at age < 69.3 years (ARD -0.90%, 95% CI -1.47% to -0.32%, HR 0.86, 95% CI 0.77 ~ 0.97). Patients with prior IS/TIA benefited most in reduced risks of three-point MACE from using DPP-4i vs. SU (ARD -4.22%, 95% CV -6.66% to -1.78%, HR 0.80, 95% CI 0.69 ~ 0.93), followed by those without prior IS/TIA and initiated with DPP-4i at age < 69.3 years (ARD -0.68%, 95% CI -1.08% to -0.29%, HR 0.81, 95% CI 0.70 ~ 0.93). Consideration of CVD and IS/TIA histories and age could facilitate individualized diabetes management of using DPP-4i vs. SU. Future studies are warranted given the hypothesis-generating nature in this exploratory research.

Dipeptidyl peptidase-4 inhibitors and cardiovascular events in patients with type 2 diabetes, without cardiovascular or renal disease. PLoS One 2020; 15:e0240141. [PMID: 33057387 PMCID: PMC7561135 DOI: 10.1371/journal.pone.0240141] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 09/20/2020] [Indexed: 12/13/2022] Open
Abstract
Background Cardiovascular safety of dipeptidyl peptidase-IV inhibitors (DPP-4i) in patients without cardiovascular or renal disease, a majority of newly diagnosed patients with type 2 diabetes often excluded from clinical trials on this association, is poorly understood. Thus, we investigate the risk of major adverse cardiovascular events (MACE) associated with DPP-4i in low-risk patients with diabetes Methods Using a new-user retrospective cohort derived from IBM MarketScan Commercial Claims and Encounters (2010–2015), we identified patients aged 35–65 with type 2 diabetes, without cardiovascular or renal disease, initiating DPP-4i, sulfonylureas, or metformin. Primary composite outcome of time to first MACE was defined as the first of any of the following: myocardial infarction, cardiac arrest, coronary artery bypass graft, coronary angioplasty, heart failure, and stroke. Secondary outcomes were time to first heart failure, acute myocardial infarction, and stroke. We compared outcomes for DPP-4i versus sulfonylurea and DPP-4i versus metformin using propensity score weighted Cox proportional hazards, adjusting for demographics, baseline comorbidities, concomitant medications, and cumulative exposure. Results Of 445,701 individuals, 236,431 (53.0%) were male, median age was 51 (interquartile range: [44, 57]), 30,267 (6.79%) initiated DPP-4i, 52,138 (11.70%) initiated sulfonylureas, and 367,908 (82.55%) initiated metformin. After adjustment, DPP-4i was associated with lower risk of MACE than sulfonylurea (adjusted hazard ratio (aHR) = 0.87; 95% confidence interval (CI): 0.78–0.98), and similar risk to metformin (aHR = 1.07; 95% CI: 0.97–1.18). Risk for acute myocardial infarction (aHR = 0.70; 95% CI: 0.51–0.96), stroke (aHR = 0.57; 95% CI: 0.41–0.79), and heart failure (aHR = 0.57; 95% CI: 0.41–0.79) with DPP-4i was lower compared to sulfonylureas. Conclusion Our findings show that for this cohort of low-risk patients newly treated for type 2 diabetes, DPP-4i exhibited 13% lower risk for MACE compared to sulfonylureas and similar risk for MACE compared to metformin, suggesting DPP-4i is a low cardiovascular risk option for low-risk patients initiating antihyperglycemic treatment.

Abstract
INTRODUCTION The dipeptidyl peptidase-4 inhibitors (DPP-4is), which belong to the class of incretin-based medications, are recommended as second or third-line therapies in guidelines for the management of type 2 diabetes mellitus. They have a favorable drug tolerability and safety profile compared to other glucose-lowering agents. OBJECTIVE This review discusses data concerning the use of DPP-4is and their cardiovascular profile, and gives an updated comparison with the other oral glucose-lowering medications with regards to safety and efficacy. Currently available original studies, abstracts, reviews articles, systematic reviews and meta-analyses were included in the review. DISCUSSION DPP4is are moderately efficient in decreasing the HbA1c by an average of 0.5% as monotherapy, and 1.0% in combination therapy with other drugs. They have a good tolerability and safety profile compared to other glucose-lowering drugs. However, there are possible risks pertaining to acute pancreatitis and pancreatic cancer. CONCLUSION Cardiovascular outcome trials thus far have proven the cardiovascular safety for ischemic events in patients treated with sitagliptin, saxagliptin, alogliptin, linagliptin and vildagliptin. Data showing increased rate of hospitalisation in the case of saxagliptin did not seem to be a class effect.

Abstract
PURPOSE In pharmacoepidemiologic studies, estimating medication adherence, persistence, and exposure patterns is critical. Constructing medication treatment episodes from prescription claims data involves assumptions related to grace period, carry-over, and lag effect, but there are no guidelines for these assumptions. We evaluated reporting and variability of these parameters in pharmacoepidemiology studies, using a case study of antihyperglycemic medications and major adverse cardiovascular events (MACE). METHODS We conducted a systemic review using MEDLINE and EMBASE for studies published prior to January 2, 2020 comparing the risk of MACE between dipeptidyl peptidase 4 (DPP-4) inhibitors and active comparators. We extracted study characteristics and results, including grace period, carry-over, and lag effect. Risk of bias was assessed by the Newcastle-Ottawa scale, and assessments for prevalent user, immortal time, time lag, and time window biases. RESULTS A total of 14/1850 studies identified were included. Grace period was not reported in 5 (35.7%) studies and ranged from 0 days to 180 days when reported. Carry-over was not reported in 10 studies (71.4%). Lag effect was not reported in nine (71.4%) studies and ranged from 0 days to 180 days when reported. No studies conducted sensitivity analyses examining the effects of these assumptions on study findings. Predominant biases were inadequate follow-up time, comparability of cohorts, prevalent use, and lag time bias. CONCLUSIONS Use of grace period, carry-over, and lag effect were poorly reported and highly variable. Future pharmacoepidemiology studies should improve reporting, justify ranges for these parameters, and conduct sensitivity analyses to evaluate effects of these assumptions.

Abstract
The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. The total diabetic population is expected to increase from 415 million in 2015 to 642 million by 2040. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of patients with type 2 diabetes died of ASCVD. The association between hyperglycemia and elevated cardiovascular (CV) risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction by conventional antidiabetic agents did not significantly reduce macrovascular outcomes.In December 2008, U.S. Food and Drug Administration issued a mandate that every new antidiabetic agent requires rigorous assessments of its CV safety. Thereafter, more than 200,000 patients have been enrolled in a number of randomized controlled trials (RCTs). These trials were initially designed to prove noninferiority. It turned out that some of these trials demonstrated superiority of some new antidiabetic agents versus placebo in reducing CV endpoints, including macrovascular events, renal events, and heart failure. These results are important in clinical practice and also provide an opportunity for academic society to formulate treatment guidelines or consensus to provide specific recommendations for glucose control in various CV diseases.In 2018, the Taiwan Society of Cardiology (TSOC) and the Diabetes Association of Republic of China (DAROC) published the first joint consensus on the "Pharmacological Management of Patients with Type 2 Diabetes and Cardiovascular Diseases." In 2020, TSOC appointed a new consensus group to revise the previous version. The updated 2020 consensus was comprised of 5 major parts: (1) treatment of diabetes in patients with multiple risk factors, (2) treatment of diabetes in patients with coronary heart disease, (3) treatment of diabetes in patients with stage 3 chronic kidney disease, (4) treatment of diabetes in patients with a history of stroke, and (5) treatment of diabetes in patients with heart failure. The members of the consensus group thoroughly reviewed all the evidence, mainly RCTs, and also included meta-analyses and real-world evidence. The treatment targets of HbA1c were finalized. The antidiabetic agents were ranked according to their clinical evidence. The consensus is not mandatory. The final decision may need to be individualized and based on clinicians' discretion.

Abstract
In recent years guidelines for the treatment of type 2 diabetes (T2DM) have evolved substantially. Initially limited to a few glucose lowering agents, early guidelines predicated strict glycemic control as a main goal in the attempt to reduce the risk of long-term diabetic complications. Nowadays, guidelines are not limited to such a goal but include cardiovascular (and renal) protection. This rapid evolution was made possible by the introduction of new glucose lowering agents, which have been extensively tested in randomized clinical studies including large cardiovascular outcome trials (CVOTs). In this review we will specifically consider the use of incretin-based medications in T2DM as recommended in the recent ADA/EASD consensus, and other international guidelines, with special consideration of their glucose-lowering efficacy, their cardiovascular (and renal) benefit, their effect on body weight and risk of hypoglycemia, as well as the economic implications for their use.

Abstract
Background Randomized controlled trials showed that newer glucose‐lowering agents are cardioprotective, but most participants were men. It is unknown whether benefits are similar in women. Methods and Results Among adults with type 2 diabetes mellitus not controlled with metformin with no prior use of insulin, we assessed for sex differences in the cardiovascular effectiveness and safety of sodium‐glucose‐like transport‐2 inhibitors (SGLT‐2i), glucagon‐like peptide‐1 receptor agonists (GLP‐1RA), dipeptidyl peptidase‐4 inhibitors, initiated as second‐line agents relative to sulfonylureas (reference‐group). We studied type 2 diabetes mellitus American adults with newly dispensed sulfonylureas, SGLT‐2i, GLP‐1RA, or dipeptidyl peptidase‐4 inhibitors (Marketscan‐Database: 2011–2017). We used multivariable Cox proportional hazards models with time‐varying exposure to compare time to first nonfatal cardiovascular event (myocardial infarction/unstable angina, stroke, and heart failure), and safety outcomes between drugs users, and tested for sex–drug interactions. Among 167 254 type 2 diabetes mellitus metformin users (46% women, median age 59 years, at low cardiovascular risk), during a median 4.5‐year follow‐up, cardiovascular events incidence was lower in women than men (14.7 versus 16.7 per 1000‐person‐year). Compared with sulfonylureas, hazard ratios (HRs) for cardiovascular events were lower with GLP‐1RA (adjusted HR‐women: 0.57, 95% CI: 0.48–0.68; aHR‐men: 0.82, 0.71–0.95), dipeptidyl peptidase‐4 inhibitors (aHR‐women: 0.83, 0.77–0.89; aHR‐men: 0.85, 0.79–0.91) and SGLT‐2i (aHR‐women: 0.58, 0.46–0.74; aHR‐men: 0.69, 0.57–0.83). A sex‐by‐drug interaction was statistically significant only for GLP‐1RA (P=0.002), suggesting greater cardiovascular effectiveness in women. Compared with sulfonylureas, risks of adverse events were similarly lower in both sexes for GLP‐1RA (aHR‐women: 0.81, 0.73–0.89; aHR‐men: 0.80, 0.71–0.89), dipeptidyl peptidase‐4 inhibitors (aHR‐women: 0.82, 0.78–0.87; aHR‐men: 0.83, 0.78–0.87) and SGLT‐2i (aHR‐women: 0.68, 0.59–0.78; aHR‐men: 0.67, 0.59–0.78) (all sex–drug interactions for adverse events P>0.05). Conclusions Newer glucose‐lowering drugs were associated with lower risk of cardiovascular events than sulfonylureas, with greater effectiveness of GLP‐1RA in women than men. Overall, they appeared safe, with a better safety profile for SGLT‐2i than for GLP‐1RA regardless of sex.

Abstract
Type 2 diabetes mellitus is a risk factor for incident heart failure and increases the risk of morbidity and mortality in patients with established disease. Secular trends in the prevalence of diabetes mellitus and heart failure forecast a growing burden of disease and underscore the need for effective therapeutic strategies. Recent clinical trials have demonstrated the shared pathophysiology between diabetes mellitus and heart failure, the synergistic effect of managing both conditions, and the potential for diabetes mellitus therapies to modulate the risk of heart failure outcomes. This scientific statement on diabetes mellitus and heart failure summarizes the epidemiology, pathophysiology, and impact of diabetes mellitus and its control on outcomes in heart failure; reviews the approach to pharmacological therapy and lifestyle modification in patients with diabetes mellitus and heart failure; highlights the value of multidisciplinary interventions to improve clinical outcomes in this population; and outlines priorities for future research.

Abstract
BACKGROUND Cardiovascular events associated with oral hypoglycemic agents (OHAs) have raised significant safety concerns. This study assessed the association between dipeptidyl peptidase-4 inhibitors (DPP-4i) and the risk of cardiovascular events in patients with type 2 diabetes mellitus with or without chronic kidney disease (CKD). STUDY DESIGN A retrospective cohort study using Taiwan's National Health Insurance Research Database. SETTINGS AND PARTICIPANTS Our study included patients with type 2 diabetes who received OHAs between March 1, 2009, and December 31, 2012. All eligible subjects were classified into CKD and non-CKD cohorts and further categorized as the DPP-4i and non-DPP-4i users in each cohort. METHODS The DPP-4i and non-DPP-4i groups were matched 1:1 by propensity score to attenuate potential selection bias. Propensity score was estimated by logistic regression, using demographics, co-medications, comorbidities. and adapted diabetic complication severity index at baseline. OUTCOMES Outcomes of interest included a composite endpoint of ischemic stroke, myocardial infarction, cardiovascular death (major adverse cardiac events [MACE]), and hospitalization for heart failure (hHF). COX proportional hazard models were applied to examine the association between DPP-4i and outcomes of interest. RESULTS We identified 37,641 and 87,604 patients with type 2 diabetes with and without CKD, respectively. After propensity score matching, 8,213 pairs of CKD patients and 12,313 pairs of non-CKD patients were included for analysis. In the CKD cohort, DPP-4i were associated with a 25% increased risk of hHF (DPP-4i vs. non-DPP-4i incidence/1,000 person-years: 15.0 vs. 9.9, HR = 1.25; 95% CI 1.01-1.54, p = 0.037) but not with the risk of MACE (HR = 0.89, p = 0.144). In the non-CKD cohort, DPP-4i were associated with a lower risk of MACE (DPP-4i vs. non-DPP-4i incidence/1,000 person-years: 9.8 vs. 12.6 HR = 0.73; 95% CI 0.61-0.87, p = 0.0007), but not the risk of hHF (HR = 1.09, p = 0.631). CONCLUSIONS DPP-4i were found to be associated with decreased risk of MACE in the non-CKD cohort in our study. However, DPP-4i were associated with increased risk of hHF in the CKD cohort. DPP-4i in the CKD cohort should be used cautiously.

Abstract
AIMS/INTRODUCTION The present study investigated the effect of high-dose metformin or low-dose metformin/linagliptin combination therapy on glycemic variability (GV) in type 2 diabetes patients with insufficient glycemic control despite low-dose metformin monotherapy in a cross-over study using continuous glucose monitoring. MATERIALS AND METHODS The present study was carried out with 11 type 2 diabetes outpatients (7% < glycated hemoglobin < 10%) receiving low-dose metformin monotherapy (500-1,000 mg). All patients were assigned to either metformin 1,500 mg monotherapy (HMET) or combination therapy of low-dose (750 mg) metformin and linagliptin 5 mg (LMET + dipeptidyl peptidase-4 [DPP4]). GV was evaluated by continuous glucose monitoring after >4 weeks of the initial treatment and again after cross-over to the other treatment. GV metrics were compared between the treatments using the Wilcoxon signed-rank test. RESULTS Of the continuous glucose monitoring-derived GV metrics for the HMET versus LMET + DPP4, mean glucose levels, standard deviations and mean amplitude of glucose excursions were not significantly different. Although the pre-breakfast glucose levels were not significantly different among the treatments (P = 0.248), the 3-h postprandial glucose area under the curve (>160 mg/dL) after breakfast was significantly larger with HMET versus LMET + DPP4 (9,550 [2,075-11,395] vs 4,065 [1,950-8,895]; P = 0.041). CONCLUSIONS A comparison of GV with HMET versus LMET + DPP4 suggested that LMET + DPP4 might reduce post-breakfast GV to a greater degree than HMET in type 2 diabetes patients receiving low-dose metformin monotherapy.

Abstract
AIMS To examine the outcomes of dipeptidyl peptidase-4 (DPP-4) inhibitor initiation with and without concurrent metformin treatment. MATERIALS AND METHODS We identified Medicare enrollees initiating a DPP-4 inhibitor, a sulphonylurea or a thiazolidinedione. Using propensity-score-weighted Poisson models, we evaluated 1-year cardiovascular (CV) outcome incidence among initiators of DPP-4 inhibitors versus comparators in subgroups with and without concurrent metformin use, and assessed the interaction between initiation drug and metformin. Outcomes included mortality, non-fatal myocardial infarction (MI), stroke, and a composite outcome. RESULTS For the DPP-4 inhibitor (n = 13 391) versus sulphonylurea (n = 33 206) comparison, rate differences in composite outcome incidence favoured DPP-4 inhibitors: -2.0/100 person-years among metformin users (95% confidence interval [CI] -2.7 to -1.3) and - 1.0/100 person-years (95% CI -1.8 to -0.2) among metformin non-users. Similar rate difference trends among metformin users and non-users were seen for mortality (-1.5/100 person-years [95% CI -2.1 to -0.9] and -0.7/100 person-years [95% CI -1.4 to 0.0]) and non-fatal MI (-0.5/100 person-years [95% CI -0.8, -0.3] and 0.1/100 person-years [95% CI -0.2 to 0.4]). The interaction between DPP-4 inhibitor initiation and metformin was statistically significant for non-fatal MI (P = 0.008). For the DPP-4 inhibitor (n = 22 210) versus thiazolidinedione (n = 9517) comparison, rate differences in composite outcome incidence for DPP-4 inhibitor initiation were -0.6/100 person-years (95% CI -1.5 to 0.2) among metformin users and 1.0 (95% CI 0.0 to 2.0) among metformin non-users. Similar rate difference trends among metformin users and non-users were seen for mortality (-0.5/100 person-years [95% CI -1.3 to 0.1] and 0.8/100 person-years [95% CI -0.0 to 1.7]) and non-fatal MI (-0.1/100 person-years [95% CI -0.4 to 0.2] and 0.2/100 person-years [95% CI -0.1 to 0.6]). The interaction between DPP-4 inhibitor initiation and metformin was statistically significant for the composite outcome (P = 0.024) and mortality (P = 0.023). CONCLUSION Incidence rate differences in multiple CV outcomes appeared more favourable when DPP-4 inhibitor initiation occurred in the presence of metformin, suggesting a possible interaction between DPP-4 inhibitors and metformin.

Abstract
IN BRIEF The number of medications used to treat diabetes has increased dramatically in the past 15 years. With so many options that have shown significant A1C improvement, it is important to consider side effects, precautions, and additional benefits these agents may offer. This article is a review of some of the most compelling literature available on the nonglycemic benefits of sulfonylureas, thiazolidinediones, biguanides, glucagon-like peptide 1 receptor agonists, dipeptidyl peptidase 4 inhibitors, and sodium-glucose cotransporter 2 inhibitors. Other classes of antihyperglycemic agents, such as dopamine agonists, meglitinides, and amylin agonists, are not discussed in this article.

Abstract
Osimertinib, a third-generation epidermal growth factor receptor - tyrosine kinase inhibitor (EGFR-TKI), shows great efficacy in EGFR-mutant non-small cell lung cancer (NSCLC); however, the resistance is inevitable. Osimertinib induces autophagy in NSCLC cells, but the role of autophagy in osimertinib resistance is not clear. We discovered that enhanced autophagy is associated with osimertinib resistance in vitro and in vivo. Inhibition of autophagy enhanced osimertinib cytotoxicity in both osimertinib-resistant and sensitive cells. Moreover, osimertinib-resistant cells exhibited stem cell-like properties, whereas autophagy inhibition decreased the stemness by downregulating the expression of SOX2 and ALDH1A1. Further, we found that knockdown of Beclin-1 inhibited the stem cell-like properties and restored osimertinib cytotoxicity. Osimertinib combined with chloroquine inhibited tumor growth more effectively than alone in xenograft mice. These results reveal that autophagy plays an adverse role in osimertinib cytotoxicity through inducing stem cell-like properties. Combination therapy of EGFR-TKI and autophagy inhibitor could provide a promising strategy to improve osimertinib cytotoxicity.

Kim KJ, Choi J, Lee J, Bae JH, An JH, Kim HY, Yoo HJ, Seo JA, Kim NH, Choi KM, Baik SH, Kim SG, Kim NH. Dipeptidyl peptidase-4 inhibitor compared with sulfonylurea in combination with metformin: cardiovascular and renal outcomes in a propensity-matched cohort study. Cardiovasc Diabetol 2019; 18:28. [PMID: 30857540 PMCID: PMC6410523 DOI: 10.1186/s12933-019-0835-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Accepted: 02/26/2019] [Indexed: 02/07/2023] Open
Abstract
Background To determine the impact of dipeptidyl peptidase-4 inhibitor (DPP4i) on the risk of major cardiocerebrovascular and renal outcomes compared with sulfonylurea (SU) combined with metformin in patients with type 2 diabetes from a population-based cohort. Methods From a nationwide cohort in Korea (2008–2013), 23,674 patients with type 2 diabetes treated with DPP4i plus metformin or SU plus metformin were selected and matched by propensity score. Composite cardiocerebrovascular events including incident ischemic heart disease (IHD), ischemic stroke (IS), hospitalization for heart failure (HHF), and cardiocerebrovascular death, as well as renal events including incident end-stage renal disease or initiation of renal-replacement therapy were assessed by Cox proportional-hazards models. Results During a median follow-up of 19.6 months (interquartile range 7.2–36.4), 762 composite cardiocerebrovascular events and 17 end-stage renal events occurred. There was no significant difference in the risk of IHD (hazard ratio [HR], 1.00; 95% CI 0.81–1.23), IS (HR, 0.95; 95% CI 0.74–1.23), or cardiocerebrovascular death (HR, 0.74; 95% CI 0.46–1.18) in the DPP4i group compared to that in the SU group. Likewise, DPP4i therapy was not associated with the risk of end-stage renal outcomes (HR, 1.23; 95% CI 0.41–3.62). However, the risk of HHF was significantly higher in the DPP4i group than in the SU group (HR, 1.47; 95% CI 1.07–2.04). Conclusions This real-world database analysis showed that DPP4i therapy did not increase the overall risk of major cardiovascular and renal outcomes compared to SU therapy. However, the DPP4i-associated risk of HHF remained significant.

Abstract
BACKGROUND Heart failure hospitalization (hHF) with dipeptyl-dipeptidase-4 inhibitors (DPP-4Is) remains at the center stage since the publication of Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus - Thrombolysis in Myocardial Infarction (SAVOR-TIMI) in 2013 showing significant increase with saxagliptin, compared to placebo. This outcome led to additional label of hHF to both saxagliptin and alogliptin in April 2016 and eventual labelling of hHF to all the four approved DPP-4Is in United States in August 2017, by US Food Drug Administration. To note, neither Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS), nor Cardiovascular and Renal Microvascular Outcome Study with Linagliptin (CARMELINA), showed any signals of hHF with these two agents. These developments have seriously generated an uncertainty among clinicians with regards to hHF effect of DPP-4Is in type 2 diabetic patients with high risk of cardiovascular (CV) disease. AIMS AND OBJECTIVES We systematically searched the database of PubMed, Embase, Cochrane Central library, ClinicalTrials.gov, and International conference presentation from the inception up to October 25, 2018 using MeSH and specific key words. We retrieved all those studies that explicitly looked for hHF as a prespecified end point and were conducted for ≥52 weeks. Subsequently, we conducted the meta-analysis using comprehensive meta-analysis software Version 3, using different sensitivity analysis to study the effect of DPP-4Is on hHF in both dedicated CV outcome trials as well as randomized controlled trials. RESULTS The meta-analysis of four exclusive dedicated CV outcome trials (N = 43,522) did not find significant increase in hHF with DPP-4 inhibitors (Fixed model Relative Risk [RR] 1.06; 95% Confidence Interval [CI], 0.96-1.17; P = 0.25; I2: 53.95%, tau2: 0.012, P = 0.089). Meta-analysis of all randomized controlled trials that explicitly looked for hHF for ≥52 weeks (N = 48,199) also did not show any significant increase in hHF (fixed model peto odds ratio 1.05; 95% CI 0.95-1.15, P = 0.36; I2: 43.74%, tau2: 0.016, P = 0.10). CONCLUSIONS This meta-analysis suggests no significant increase in hHF with DPP-4 inhibitors, although a nonsignificant heterogeneity across the trials might limit this observation.

Abstract
IMPORTANCE Results of clinical trials suggest that canagliflozin, a sodium-glucose cotransporter 2 (SGLT-2) inhibitor for treating type 2 diabetes, may be associated with lower extremity amputation. OBJECTIVE To quantify the association between the use of oral medication for type 2 diabetes and 5 outcomes (lower extremity amputation, peripheral arterial disease, critical limb ischemia, osteomyelitis, and ulcer). DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted using Truven Health MarketScan Commercial Claims and Encounters data on new users between September 1, 2012, and September 30, 2015. The study focused on 2.0 million commercially insured individuals and used propensity score weighting to balance baseline differences among groups. Sensitivity analyses varied statistical models, assessed the effect of combining dipeptidyl peptidase 4 (DPP-4) inhibitors and glucagon-like peptide 1 (GLP-1) agonists as a single referent group, adjusted for baseline use of older oral agents, and included people with baseline amputation. EXPOSURES New use of SGLT-2 inhibitors alone, DPP-4 inhibitors alone, GLP-1 agonists alone, or other antidiabetic agents (sulfonylurea, metformin hydrochloride, or thiazolidinediones). MAIN OUTCOMES AND MEASURES Foot and leg amputation, defined by validated International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes. RESULTS Among 2.0 million potentially eligible individuals, a total of 953 906 (516 046 women and 437 860 men; mean [SD] age, 51.8 [10.9] years) were included in the final analyses, including 39 869 new users of SGLT-2 inhibitors (4.2%), 105 023 new users of DPP-4 inhibitors (11.0%), and 39 120 new users of GLP-1 agonists (4.1%). The median observation time ranged from 99 days for new users of GLP-1 agonists to 127 days for those using metformin, sulfonylureas, and thiazolidinediones, while the crude incident rates ranged from 4.90 per 10 000 person-years for those using metformin, sulfonylureas, and thiazolidinediones to 10.53 per 10 000 person-years for new users of SGLT-2 inhibitors. After propensity score weighting and adjustment for demographics, severity of diabetes, comorbidities, and medications, there was a nonstatistically significant increased risk of amputation associated with new use of SGLT-2 inhibitors compared with DPP-4 inhibitors (adjusted hazard ratio, 1.50; 95% CI, 0.85-2.67) and GLP-1 agonists (adjusted hazard ratio, 1.47; 95% CI, 0.64-3.36). New use of SGLT-2 inhibitors was statistically significantly associated with amputation compared with sulfonylureas, metformin, or thiazolidinediones (adjusted hazard ratio, 2.12; 95% CI, 1.19-3.77). These results persisted in sensitivity analyses. CONCLUSIONS AND RELEVANCE Use of SGLT-2 inhibitors may be associated with increased risk of amputation compared with some oral treatments for type 2 diabetes. Further observational studies are needed with extended follow-up and larger sample sizes.

ENDOCRINOLOGY DIABETES & METABOLISM 2018; 1:e00036.

Abstract
Aims The understanding of second-line use of glucose-lowering drugs (GLDs) in the general population with type 2 diabetes (T2D) treatment is important as recent results have shown cardiovascular benefits with sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA). Our aim was to describe second-line GLD treatment patterns in four Nordic countries. Methods All T2D patients treated with GLD between 2006 and 2015 were identified in prescribed drug registries in Denmark, Finland, Norway and Sweden, and linked with National Patient and Cause of Death Registries. Second-line treatment was defined as a prescription of a second GLD class following ≥6 months of metformin monotherapy. Index was the date of first dispense of the second-line drug. Results A rapid uptake of newer GLDs (GLP-1RA, DPP-4i and SGLT-2i) over the 10-year observation period was seen in Denmark, Finland and Norway, while slower in Sweden. In 2015, 33,880 (3.1%) of 1,078,692 T2D patients initiated second-line treatment, and newer GLDs were more commonly used in Finland (92%), Norway (71%) and Denmark (70%) vs Sweden (44%). In 2015, the use of older GLDs (insulin and sulphonylureas) was 7-fold greater in Sweden compared to Finland (49% vs 7%), and 1.6-fold greater compared with Denmark and Norway (49% vs 30% and 29%, respectively). Conclusions Despite comparable demography and healthcare systems in four neighbouring countries, surprisingly large differences in second-line use of newer GLDs were found. With recent evidence of potential cardiovascular benefits with newer GLDs, such differences may have an important impact on cardiovascular outcomes.

Abstract
OBJECTIVE The objective of this study is to determine whether vaccination against influenza is associated with a reduced risk of acute kidney injury (AKI) in a nationwide cohort of adults aged ≥65 years. METHODS We investigated a total of 13,270 patients aged ≥65 years who were hospitalized for AKI between 2000 and 2013 from Taiwan's National Health Insurance Research Database. Each AKI case was matched with one control subject according to duration of follow-up, age, sex, monthly income, urbanization level, and baseline comorbidities. Odds ratios (ORs) for AKI associated with exposure to the influenza vaccine in the previous year were calculated in a nested case-control analysis. RESULTS Influenza vaccination in the previous year was associated with a lower risk of AKI (adjusted OR 0.67, 95% confidence interval [CI] 0.63-0.72). Compared with a reference group of unvaccinated individuals with no influenza infection, vaccination with no influenza infection was associated with a lower risk of AKI (adjusted OR 0.68, 95% CI 0.64-0.73). Lack of vaccination and presence of influenza infection was associated with a higher risk of AKI (adjusted OR 1.78, 95% CI 1.57-2.01), whereas the risk of AKI was insignificant in vaccinated patients who developed influenza (adjusted OR 1.01, 95% CI 0.69-1.18). CONCLUSIONS The risk of AKI was 37% lower among older people who received vaccination against influenza in a real-world setting. Further work is required to clarify causality.

Abstract
AIMS The aim of this study was to investigate the putative link between dipeptidyl peptidase-4 inhibitor (DPP-4i) use and the risk of fracture in patients with type 2 diabetes. METHODS This propensity-score-matched population-based cohort study was performed between 2009 and 2013 on patients with type 2 diabetes who were stable metformin users. A total of 3996 patients with type 2 diabetes used DPP-4i as a second-line antidiabetic drug. The same number of matched non-DPP-4i users were followed up until fracture occurrence, health insurance policy termination, or the end of 2013. The incidence rates of overall and cause-specific fractures were estimated based on the Poisson assumption. A multiple Cox proportional hazard model was used to estimate the covariate-adjusted hazard ratio (HR) and 95% confidence interval (CI) to determine the association between DPP-4i use and overall and cause-specific fractures stratified by age and sex. RESULTS Over a maximum follow-up period of 5 years, 340 DPP-4i users and 419 non-DPP-4i users were newly diagnosed with fractures, yielding incidence rates of 28.03 and 32.04 per 1000 people per year, respectively. The Cox proportional hazard model revealed that DPP-4i use significantly reduced the risk of all-cause fractures and upper extremity fractures, with adjusted HRs of 0.86 (95% CI: 0.74-0.99) and 0.75 (95% CI: 0.59-0.95), respectively. The aforementioned associations of DDP-4i use with fracture were sustained across sex and age stratifications. CONCLUSIONS The results of this study supported the premise that DPP-4i usage is associated with a reduced risk of all-cause fractures and upper extremity fractures in patients with type 2 diabetes.

Abstract
After failure of metformin monotherapy, another glucose-lowering agent should be added to improve glucose control. The clinician has several pharmacological choices, including the addition of a sulphonylurea (SU) or a dipeptidyl peptidase-4 inhibitor (DPP-4i). While the cardiovascular safety of SUs remains a matter of controversy, DPP-4is have proven their non-inferiority vs placebo in recent cardiovascular (CV) outcome trials. In the absence of a head-to-head CV outcome trial-the CAROLINA, comparing linagliptin with glimepiride, is still ongoing-only indirect information can be found in the literature to compare CV outcomes (major CV events, myocardial infarction, ischaemic stroke, CV death and all-cause mortality) in patients with type 2 diabetes mellitus (T2DM) treated with SUs or DPP-4is. Thus, this comprehensive review summarizes the CV outcomes (excluding heart failure) reported in meta-analyses of randomized controlled trials (RCTs) of SUs vs placebo or other glucose-lowering agents, DPP-4is vs placebo or other glucose-lowering agents and SUs vs DPP-4is in phase-II/III studies. Also, the results of observational studies reporting CV events in patients treated with either SUs or DPP-4is have been carefully examined. Overall, the CV safety of SUs appears to be poorer than that of DPP-4is in both RCTs and cohort studies. However, the results are somewhat disparate, and such heterogeneity may be explained by different patient characteristics across studies, but also perhaps by differences between various molecules in each pharmacological class. In particular, some doubt about a class effect affecting SU CV safety has been raised. The results of CAROLINA are expected to shed more light on SU CV concerns, especially compared with DPP-4is.

Abstract
INTRODUCTION Dipeptidyl peptidase-4 inhibitors (DPP-4is) are generally considered as glucose-lowering agents with a safe profile in type 2 diabetes. AREAS COVERED An updated review of recent safety data from randomised controlled trials, observational studies, meta-analyses, pharmacovigilance reports regarding alogliptin, linagliptin, saxagliptin, sitagliptin, and vildagliptin, with a special focus on risks of hypoglycemia, pancreatitis and pancreatic cancer, major cardiovascular events, hospitalisation for heart failure and other new safety issues, such as bone fractures and arthralgia. The safety of DPP-4i use in special populations, elderly patients, patients with renal impairment, liver disease or heart failure, will also be discussed. EXPERT OPINION The good tolerance/safety profile of DPP-4is has been largely confirmed, including in more fragile populations, with no gastrointestinal adverse effects and a minimal risk of hypoglycemia. DPP-4is appear to be associated with a small increased incidence of acute pancreatitis in placebo-controlled trials, although most observational studies are reassuring. Most recent studies with DPP-4is do not confirm the increased risk of hospitalisation for heart failure reported with saxagliptin in SAVOR-TIMI 53, but further post-marketing surveillance is still recommended. New adverse events have been reported such as arthralgia, yet a causal relationship remains unclear.

Abstract
Background and Objectives: Limited research focuses on the risk of ischemic cerebrovascular disease associated with use of dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) in patients with type 2 diabetes mellitus in Taiwan. This study aimed to investigate the association between DPP-4 inhibitors use and the first episode of ischemic cerebrovascular disease. Methods: We designed a case-control study using the database of the Taiwan National Health Insurance Program. There were 1999 type 2 diabetic subjects aged 20-84 years with the first episode of ischemic cerebrovascular disease from 2000 to 2013 as the cases, and 7996 sex- and age-matched, randomly selected type 2 diabetic subjects aged 20-84 years without any type of cerebrovascular diseases as the matched controls. We estimated the odds ratio (OR) and 95% confidence interval (CI) of ischemic cerebrovascular disease associated with cumulative duration of DPP-4 inhibitors use by the multivariable logistic regression model. Results: After adjustment for confounding variables, the adjusted OR of ischemic cerebrovascular disease was 0.96 (95% CI 0.95, 0.97) in subjects with ever use of DPP-4 inhibitors as increase in use duration for every 1 month, compared with never use. The sub-analysis disclosed that the adjusted ORs of ischemic cerebrovascular disease were 1.57 (95% CI 1.36, 1.80) for subjects with cumulative duration of DPP-4 inhibitors use <1 year, and 0.70 (95% CI 0.57, 0.87) for subjects with cumulative duration of DPP-4 inhibitors use ≥1 year, compared with never use. Conclusion: Our findings suggest that DPP-4 inhibitors use correlates with relative risk reduction of the first episode of ischemic cerebrovascular disease in type 2 diabetic patients in a duration-dependent response. The beneficial effect will be marked when DPP-4 inhibitors use is ≥1 year.

Abstract
Background Preventable drug-related hospital admissions can be associated with drugs used in diabetes and the benefits of strict diabetes control may not outweigh the risks, especially in older populations. The aim of this study was to look for evidence on risks and benefits of DPP-4 inhibitors in older adults and to use this evidence to develop recommendations for the electronic decision support tool of the PRIMA-eDS project. Methods Systematic review using a staged approach which searches for systematic reviews and meta-analyses first, then individual studies only if prior searches were inconclusive. The target population were older people (≥65 years old) with type 2 diabetes. We included studies reporting on the efficacy and/or safety of DPP-4 inhibitors for the management of type 2 diabetes. Studies were included irrespective of DPP-4 inhibitors prescribed as monotherapy or in combination with any other drug for the treatment of type 2 diabetes. The target intervention was DPP-4 inhibitors compared to placebo, no treatment, other drugs to treat type 2 diabetes or a non-pharmacological intervention. Results Thirty studies (reported in 33 publications) were included: 1 meta-analysis, 17 intervention studies and 12 observational studies. Sixteen studies were focused on older adults and 14 studies reported subgroup analyses in participants ≥65, ≥70, or ≥75 years. Comorbidities were reported by 26 studies and frailty or functional status by one study. There were conflicting findings regarding the effectiveness of DPP-4 inhibitors in older adults. In general, DPP-4 inhibitors showed similar or better safety than placebo and other antidiabetic drugs. However, these safety data are mainly based on short-term outcomes like hypoglycaemia in studies with HbA1c control levels recommended for younger people. One recommendation was developed advising clinicians to reconsider the use of DPP-4 inhibitors for the management of type 2 diabetes in older adults with HbA1c <8.5% because of scarce data on clinically relevant benefits of their use. Twenty-two of the included studies were funded by pharmaceutical companies and authored or co-authored by employees of the sponsor. Conclusions Other than the surrogate endpoint of improved glycaemic control, data on clinically relevant benefits of DPP-4 inhibitors in the treatment of type 2 diabetes mellitus in older adults is scarce. DPP-4 inhibitors might have a lower risk of hypoglycaemia compared to other antidiabetic drugs but data show conflicting findings for long-term benefits. Further studies are needed that evaluate the risks and benefits of DPP-4 inhibitors for the management of type 2 diabetes mellitus in older adults, using clinically relevant outcomes and including representative samples of older adults with information on their frailty status and comorbidities. Studies are also needed that are independent of pharmaceutical company involvement.

Abstract
BACKGROUND Clinical trials assessing the combination therapy of metformin plus dipeptidyl peptidase-4 inhibitors versus metformin plus Sulfonylureas on risk of cardiovascular disease, cardiovascular mortality and/or all-cause mortality in type 2 diabetes have shown conflicting results. We therefore evaluated the combination therapy on the risk of cardiovascular disease, cardiovascular mortality and/or all-cause mortality in type 2 diabetes. METHODS A systematic search of Medline/PubMed (from 2000 to September 2015), EMBASE (from 2000 to September 2015), and Web of Knowledge (from 2000 to September 2015) for research articles published in English was carried out to examine how combination therapy affects the risk of CVD mortality and/or all-cause mortality in T2DM patients. In addition, the risks of cardiovascular events, CVD mortality, and/or all-cause mortality as well as the adjusted relative risk (RR) or equivalent (hazard ratio or odds ratio) and the corresponding variance or equivalent are reported. RESULTS The accumulative RRs (95% confidence intervals) for T2DM patients treated with the combination therapy of metformin plus DPP-4 inhibitor versus metformin plus sulfonylurea were 0.71 (0.56-0.90) for nonfatal cardiovascular events, 1.001 (0.85-1.18) for fatal cardiovascular events, 0.58 (0.41-0.82) for CVD mortality, and 0.72 (0.59-0.87) for all-cause mortality. CONCLUSIONS The combination therapy of metformin plus DPP-4 inhibitor significantly decreased the RR of nonfatal cardiovascular events, CVD mortality, and all-cause mortality, compared with the combination therapy of metformin plus sulfonylurea. However, the number fatal cardiovascular events (e.g., heart failure) was not significantly different between the 2 groups.

Abstract
AIM To compare the cardiovascular (CV) risk associated with dipeptidyl peptidase-4 (DPP-4) inhibitors relative to sulphonylureas (SUs) and thiazolidinediones (TZDs). METHODS During 2007 to 2013, using Medicare data for beneficiaries aged >65 years, we identified the following 2 cohorts of new-users, who had not been exposed to the drugs being compared in the 6 months before initiation: (1) DPP-4 inhibitor vs SU initiators and (2) DPP-4 inhibitor vs TZD initiators. Using propensity-score-adjusted Cox models accounting for competing risk by death, we estimated the hazard ratios (HRs), risk differences and 95% confidence intervals (CIs) for myocardial infarction (MI), stroke, hospitalization for heart failure (HF), and a combined outcome (MI, stroke, all-cause mortality). RESULTS In the DPP-4 inhibitor vs SU comparison, there were 30 130 DPP-4 inhibitor initiators and 68 382 SU initiators. Their mean age was 75 years, 41% were men and 55% had a baseline CV condition. The HR for the composite outcome was 0.75 (95% CI 0.72-0.79) over a median treatment duration of 1 year, but the 1-year risks of MI were 1.00 (95% CI 0.89-1.12) and 1.47 (95% CI 1.38-1.56) per 100 patients for DPP-4 inhibitors and SUs, respectively, and the corresponding stroke risks were 0.98 (95% CI 0.87-1.10) and 1.09 (95% CI 1.01-1.17). For the DPP-4 inhibitor vs TZD comparison, there were 20 596 DPP-4 inhibitor initiators and 13 526 TZD initiators without previous HF. Their mean age was 74 years, 42% were men and 30% had a baseline CV event. The composite outcome HR was 0.94 (95% CI 0.86-1.02) over a median treatment duration of 1 year. The 1-year risk for MI was ~0.90 and for stroke it was ~0.80 per 100 patients in both DPP-4 inhibitor and TZD initiators. CONCLUSION Although limited by the short treatment period, the present study suggests there is no increased short-term risk of MI, stroke or HF with DPP-4 inhibitors vs SUs/TZDs.

Abstract
Epidemiologic and clinical data from the last 2 decades have shown that the prevalence of heart failure in diabetes is very high, and the prognosis for patients with heart failure is worse in those with diabetes than in those without diabetes. Experimental data suggest that various mechanisms contribute to the impairment in systolic and diastolic function in patients with diabetes, and there is an increased recognition that these patients develop heart failure independent of the presence of coronary artery disease or its associated risk factors. In addition, current clinical data demonstrated that treatment with the sodium glucose cotransporter 2 inhibitor empagliflozin reduced hospitalization for heart failure in patients with type 2 diabetes mellitus and high cardiovascular risk. This review article summarizes recent data on the prevalence, prognosis, pathophysiology, and therapeutic strategies to treat patients with diabetes and heart failure.

J Clin Endocrinol Metab 2017; 102:2373-2381. [PMID: 28398564 DOI: 10.1210/jc.2016-3717] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2016] [Accepted: 04/03/2017] [Indexed: 02/13/2023]
Abstract
CONTEXT Although there is evidence to support the beneficial effects of statins on major cardiovascular events, few studies address the protective effect of statins on limb outcome. OBJECTIVE To investigate whether the use of statin is associated with a risk reduction in lower-extremity amputation in type 2 diabetes mellitus (DM) patients with peripheral arterial disease (PAD). DESIGN Observational cohort study. SETTING A nationwide DM database in Taiwan from 2000 to 2011. PATIENTS A total of 69,332 patients aged ≥20 years with DM and PAD were identified. INTERVENTION Patients were divided into three groups: 11,409 patients were statin users, 4430 patients used nonstatin lipid-lowering agents, and 53,493 patients were nonusers. MAIN OUTCOME MEASURES The primary outcome was lower-extremity amputation. Secondary outcomes were in-hospital cardiovascular death and all-cause mortality. RESULTS Compared with nonusers, statin users were associated with lower risks of lower-extremity amputation [adjusted hazard ration (aHR), 0.75; 95% confidence interval (CI), 0.62 to 0.90], in-hospital cardiovascular death (aHR, 0.78; 95% CI, 0.69 to 0.87), and all-cause mortality (aHR, 0.73; 95% CI, 0.69 to 0.77). In the propensity score matching analysis, the effect of statin on the risk of lower-extremity amputation was consistent. Only statin users were associated with the risk reduction of lower-extremities amputation (HR, 0.77; 95% CI, 0.61 to 0.97) and cardiovascular death (HR, 0.78; 95% CI, 0.68 to 0.89) when taking competing risk of death into consideration. CONCLUSIONS Compared with statin nonusers who were never treated with lipid-lowering drugs, this study found that statin users had a lower risk of lower-extremity amputation and cardiovascular death in patients with DM and PAD.
