Leveraging a Bayesian Approach in a Comparative Effectiveness Trial of Major Adverse Cardiovascular Events

To investigate the risk of hyperkalaemia in new users of sodium-glucose cotransporter 2 (SGLT2) inhibitors vs. dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who commenced treatment with an SGLT2 or a DPP-4 inhibitor between 2015 and 2019 were collected. A multivariable Cox proportional hazards analysis was applied to compare the risk of central laboratory-determined severe hyperkalaemia, hyperkalaemia, hypokalaemia (serum potassium ≥6.0, ≥5.5, and <3.5mmol/L, respectively), and initiation of a potassium binder in patients newly prescribed an SGLT2 or a DPP-4 inhibitor. A total of 28599 patients (mean age 60±11 years, 60.9% male) were included after 1:2 propensity score matching, of whom 10586 were new users of SGLT2 inhibitors and 18013 of DPP-4 inhibitors. During a 2-year follow-up, severe hyperkalaemia developed in 122 SGLT2 inhibitor users and 325 DPP-4 inhibitor users. Use of SGLT2 inhibitors was associated with a 29% reduction in incident severe hyperkalaemia [hazard ratio (HR) 0.71, 95% confidence interval (CI) 0.58-0.88] compared with DPP-4 inhibitors. Risk of hyperkalaemia (HR 0.81, 95% CI 0.71-0.92) and prescription of a potassium binder (HR 0.74, 95% CI 0.67-0.82) were likewise decreased with SGLT2 inhibitors compared with DPP-4 inhibitors. Occurrence of incident hypokalaemia was nonetheless similar between those prescribed an SGLT2 inhibitor and those prescribed a DPP-4 inhibitor (HR 0.90, 95% CI 0.81-1.01). Our study provides real-world evidence that compared with DPP-4 inhibitors, SGLT2 inhibitors were associated with lower risk of hyperkalaemia and did not increase the incidence of hypokalaemia in patients with T2DM.

Nonalcoholic fatty liver disease (NAFLD) is a cardiovascular risk factor, but whether sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) are associated with reduced cardiovascular risk in patients with type 2 diabetes (T2D) and concomitant NAFLD remains uncertain. To investigate the outcomes of SGLT-2i and GLP-1RA therapy among patients with T2D varied by the presence or absence of NAFLD. This retrospective, population-based, nationwide cohort study used an active-comparator new-user design. Two distinct new-user active-comparator cohorts of patients aged 40 years and older who initiated SGLT-2i or GLP-1RA were propensity score matched to patients who initiated dipeptidyl peptidase-4 inhibitors (DPP-4i). The study was conducted in South Korea from January 2013 to December 2020, and data analysis was conducted from October 2022 to March 2023. The main outcomes were (1) major adverse cardiovascular events (MACE), a composite end point of hospitalization for myocardial infarction, hospitalization for stroke, and cardiovascular death, and (2) hospitalization for heart failure (HHF). Cox proportional hazards models were used to estimate hazard ratios (HRs). The Wald test was applied to assess heterogeneity by NAFLD. After 1:1 propensity score matching, 140 438 patients were retrieved in the first cohort (SGLT-2i vs DPP-4i; mean [SD] age, 57.5 [10.3] years; 79 633 [56.7%] male) and 34 886 patients were identified in the second cohort (GLP-1RA vs DPP-4i; mean [SD] age, 59.5 [10.5] years; 17 894 [51.3%] male). Compared with DPP-4i, SGLT-2i therapy was associated with a lower risk of MACE (HR, 0.78 [95% CI, 0.71-0.85]) and HHF (HR, 0.62 [95% CI, 0.48-0.81]). GLP-1RA therapy was associated with a decreased risk of MACE (HR, 0.49 [95% CI, 0.39-0.62]) but had statistically nonsignificant findings regarding HHF (HR, 0.64 [95% CI, 0.39-1.07]). Stratified analysis by NAFLD status yielded consistent results for SGLT-2i (MACE with NAFLD: HR, 0.73 [95% CI, 0.62-0.86]; without NAFLD: HR, 0.81 [95% CI, 0.72-0.91]; HHF with NAFLD: HR, 0.76 [95% CI, 0.49-1.17]; without NAFLD: HR, 0.56 [95% CI, 0.40-0.78]) and for GLP-1RA (MACE with NAFLD: HR, 0.49 [95% CI, 0.32-0.77]; without NAFLD: HR, 0.49 [95% CI, 0.37-0.65]; HHF with NAFLD: HR, 0.82 [95% CI, 0.38-1.76]; without NAFLD: HR, 0.54 [95% CI, 0.27-1.06]). In this population-based cohort study, SGLT-2i therapy was associated with a decreased risk of MACE and HHF, while GLP-1RA therapy was associated with a decreased risk of MACE among patients with T2D, irrespective of baseline NAFLD status.

Risk of cardiovascular events and death associated with initiation of SGLT2 inhibitors compared with DPP-4 inhibitors: an analysis from the CVD-REAL 2 multinational cohort study

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors with pleiotropic effects beyond glycemic control potentially improve clinical outcomes in cirrhosis; however, large-scale human evidence remains limited. We aimed to compare liver outcomes and mortality risk in adults with type 2 diabetes and compensated cirrhosis, who initiated either SGLT-2 inhibitors or dipeptidyl peptidase-4 (DPP-4) inhibitors. Using the TriNetX Global Collaborative Network and a target trial emulation framework, we identified adults with compensated cirrhosis and type 2 diabetes initiating an SGLT-2- or DPP-4 inhibitor between 2016 and 2024. Baseline demographics, laboratory information, comorbidities and concomitant medications were matched by propensity scores. The primary outcome was a composite of incident hepatic decompensation, hepatocellular carcinoma and all-cause mortality. We used Cox proportional hazards models to estimate the hazard ratios (HR) with 95% confidence intervals (CI). We included 5,398 patients (mean [SD] age: 63.9 [10.3] years), receiving SGLT-2 inhibitors, matched to 5,398 DPP-4 inhibitor users, with an overall mean follow-up of 49.8months. Compared to DPP-4 inhibitors, SGLT-2 inhibitors were associated with a lower risk of the primary composite outcome (HR: 0.85, 95% CI: 0.79-0.91), with similar results for all-cause mortality (HR: 0.77, 95% CI: 0.69-0.85) and incident hepatic decompensation (HR: 0.89, 95% CI: 0.82-0.96), but not for hepatocellular carcinoma (HR: 0.96, 95% CI: 0.82-1.14). Among adults with compensated cirrhosis and type 2 diabetes, SGLT-2 inhibitors were associated with lower risk of all-cause mortality and incident hepatic decompensation, compared to DPP-4 inhibitors. Future clinical trials are warranted to confirm this observation.

ObjectivesTo evaluate the comparative effectiveness of sodium-glucose cotransporter-2 (SGLT-2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and dipeptidyl peptidase-4 (DPP-4) inhibitors in preventing hyperkalemia in people with type 2 diabetes in...

IntroductionThe association between sodium-glucose cotransporter-2 (SGLT2) inhibitors and the risk of urogenital infections remains controversial. This study aimed to investigate the association between SGLT2 inhibitors and the incidence of perineal soft tissue infections, including Fournier's gangrene (FG), genital bacterial infections, and urinary tract infections (UTIs), using administrative claims data in Japan.MethodsIn this retrospective cohort study, we utilized the JMDC Claims Database. The study included patients aged 18 years or older diagnosed with type 2 diabetes mellitus, identified by a diagnostic code, who received new prescriptions for SGLT2 inhibitors or dipeptidyl peptidase 4 (DPP-4) inhibitors between April 2014 and August 2020. Using one-to-one propensity score (PS) matching, we compared the incidence of perineal soft tissue infections, including FG, genital bacterial infection, and UTIs between groups treated with SGLT2 and DPP-4 inhibitors. Hazard ratios (HR) and their 95% confidence intervals (CI) were estimated using the Cox proportional hazards model.ResultsWe identified 34,897 patients in the SGLT2 inhibitor group and 135,311 patients in the DPP-4 inhibitor group. After one-to-one PS matching, 31,665 pairs were generated. The mean age of the patients was 51 years, with approximately 70% being male. The use of SGLT2 inhibitors was associated with a decreased risk of UTI (HR 0.90, 95% CI 0.83–0.98) and an increased risk of genital bacterial infection (HR 1.23, 95% CI 1.03–1.46) compared to DPP-4 inhibitors. However, no significant association was observed with perineal soft tissue infection (HR 1.05, 95% CI 0.61–1.81).ConclusionsSGLT2 inhibitors were associated with a reduced risk of UTI and an increased risk of genital bacterial infection. They showed no significant association with perineal soft tissue infection when compared to DPP-4 inhibitors. Future research should explore broader demographics, focusing on the elderly and achieving gender balance, to gain a comprehensive understanding of infection risks.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13300-024-01613-7.

AimsThe effectiveness and limb safety of sodium glucose co-transporter 2 inhibitors (SGLT2i) for patients with type-2 diabetes (T2D) who have received peripheral artery disease (PAD) revascularization are unknown.Methods and resultsIn this nationwide retrospective cohort study, we identified a total of 2,455 and 8,695 patients with T2D who had undergone PAD revascularization and received first prescriptions for SGLT2i and dipeptidyl peptidase-4 inhibitors (DPP4i), respectively, between May 1, 2016, and December 31, 2019. We used 1:1 propensity score matching (PSM) to balance covariates between the two study groups. Patients were followed up from the drug index date until the occurrence of specified outcomes, death, discontinuation of the index drug, or the end of the study period, whichever occurred first. After PSM, we observed that compared with DPP4i, SGLT2i were associated with comparable risks of ischemic stroke, acute myocardial infarction, and heart failure hospitalization but were associated with a lower risk of cardiac death (hazard ratio [HR]: 0.60; 95% confidence interval [CI]: 0.40–0.90]; p = 0.0126). Regarding major limb outcomes, SGLT2i were associated with comparable risks of repeated revascularization and lower limb amputation compared with DPP4i. SGLT2i were associated with a lower risk of composite renal outcomes (HR: 0.40; 95% CI: 0.27–0.59; p < 0.0001) compared with DPP4i.ConclusionIn a real-world study of patients with T2D who had undergone PAD revascularization, SGLT2i were associated with lower risks of cardiac death and composite renal outcomes but not associated with increased risks of adverse limb events compared with DPP4i.

Introduction and Objective: The cardio-renoprotective properties of sodium-glucose cotransporter-2 (SGLT-2) inhibitors, angiotensin receptor blockers (ARBs), and angiotensin-converting enzyme (ACE) inhibitors are well-documented; however, their effectiveness in primary prevention among individuals with diabetes mellitus and hypertension, without preexisting cardiovascular (CV) or kidney disease, remains uncertain. This study evaluates the potential synergistic benefits of combining SGLT-2 inhibitors with ARB or ACE inhibitors. Methods: The study used the National Health Insurance Service-National Health Information Database (NHIS-NHID) from January 2014 to December 2022. Using propensity score matching weights to adjust for baseline imbalances, four treatment groups were analyzed: SGLT-2 inhibitor + ARB or ACE inhibitor (RAS inhibitors), SGLT-2 inhibitor + calcium channel blocker (CCB), dipeptidyl peptidase-4 (DPP-4) inhibitor + RAS inhibitors, and DPP-4 inhibitor + CCB (reference group), each combined with metformin. Weighted Cox proportional hazards regression assessed the association between treatment groups and composite CV and renal outcomes. Results: A total of 12,339 patients were originally included in the analysis, with a median follow-up duration of 31.7 months (IQR, 19.6-46.8). For renal composite outcomes, SGLT-2 inhibitors combined with RAS inhibitors (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.38-0.93; p=0.022) showed the lowest risk, followed by SGLT-2 inhibitors and CCB (HR, 0.73; 95% CI, 0.46-1.18), DPP-4 inhibitors and RAS inhibitors (HR, 1.07; 95% CI, 0.79-1.44), and DPP-4 inhibitors and CCB (reference group). CV outcomes showed no significant differences across groups. Conclusion: Combining SGLT-2 inhibitors with RAS inhibitors offers substantial renoprotective benefits in individuals without CV or kidney disease. Disclosure Y. Kim: None. J.A. Kim: None. J.

Patients with type 2 diabetes (T2D) who undergo percutaneous coronary intervention (PCI) are at higher risk of adverse cardiovascular and renal events than non-diabetic patients. However, limited evidence is available regarding the cardiovascular, renal, and limb outcomes of patients with T2D after PCI and who were treated with sodium-glucose cotransporter-2 inhibitors (SGLT2i). We compare the specified outcomes in patients with T2D after PCI who were treated with SGLT2i vs. dipeptidyl peptidase-4 inhibitors (DPP4i). In this nationwide retrospective cohort study, we identified 4248 and 37037 consecutive patients with T2D who underwent PCI with SGLT2i and DPP4i, respectively, for 1 May 2016-31 December 2019. We used propensity score matching (PSM) to balance the covariates between study groups. After PSM, SGLT2i, and DPP4i were associated with comparable risks of ischaemic stroke, acute myocardial infarction, and lower limb amputation. However, SGLT2i was associated with significantly lower risks of heart failure hospitalization [HFH; 1.35% per year vs. 2.28% per year; hazard ratio (HR): 0.60; P=0.0001], coronary revascularization (2.33% per year vs. 3.36% per year; HR: 0.69; P=0.0003), composite renal outcomes (0.10% per year vs. 1.05% per year; HR: 0.17; P<0.0001), and all-cause mortality (2.27% per year vs. 3.80% per year, HR: 0.60; P<0.0001) than were DPP4i. Our data indicated that SGLT2i, compared with DPP4i, were associated with lower risks of HFH, coronary revascularization, composite renal outcomes, and all-cause mortality for patients with T2D after PCI. Further randomized or prospective studies can investigate the effects of SGLT2i in patients with T2D after PCI.

New Glucose-Lowering Agents for Diabetic Kidney Disease.

Prior studies evaluating risk for severe urinary tract infections (UTIs) with sodium-glucose cotransporter-2 (SGLT-2) inhibitors have reported conflicting findings. To assess whether patients initiating use of SGLT-2 inhibitors were at increased risk for severe UTI events compared with those initiating use of dipeptidyl peptidase-4 (DPP-4) inhibitors or glucagon-like peptide-1 receptor (GLP-1) agonists. Population-based cohort study. 2 large, U.S.-based databases of commercial claims (March 2013 to September 2015). Within each database, 2 cohorts were created and matched 1:1 on propensity score. Patients were aged 18 years or older, had type 2 diabetes mellitus, and were initiating use of SGLT-2 inhibitors versus DPP-4 inhibitors (cohort 1) or GLP-1 agonists (cohort 2). The primary outcome was a severe UTI event, defined as a hospitalization for primary UTI, sepsis with UTI, or pyelonephritis; the secondary outcome was outpatient UTI treated with antibiotics. Hazard ratios (HRs) were estimated in each propensity score-matched cohort, with adjustment for more than 90 baseline characteristics. After 1:1 matching on propensity score, 123752 patients were identified in cohort 1 and 111978 in cohort 2 in the 2 databases. In cohort 1, persons newly receiving SGLT-2 inhibitors had 61 severe UTI events (incidence rate [IR] per 1000 person-years, 1.76), compared with 57 events in the DPP-4 inhibitor group (IR, 1.77) (HR, 0.98 [95% CI, 0.68 to 1.41]). In cohort 2, those receiving SGLT-2 inhibitors had 73 events (IR, 2.15), compared with 87 events in the GLP-1 agonist group (IR, 2.96) (HR, 0.72 [CI, 0.53 to 0.99]). Findings were robust across sensitivity analyses; within several subgroups of age, sex, and frailty; and for canagliflozin and dapagliflozin individually. In addition, SGLT-2 inhibitors were not associated with increased risk for outpatient UTIs (cohort 1: HR, 0.96 [CI, 0.89 to 1.04]; cohort 2: HR, 0.91 [CI, 0.84 to 0.99]). Generalizability of the study findings may be limited to patients with commercial insurance. In a large cohort of patients seen in routine clinical practice, risk for severe and nonsevere UTI events among those initiating SGLT-2 inhibitor therapy was similar to that among patients initiating treatment with other second-line antidiabetic medications.

Recent clinical trials suggest benefit of anti-hyperglycemic drugs on kidney outcomes. However, there is a paucity of information available on the real-world impact.We aimed to study the real-world impact of anti-hyperglycemic drugs (metformin, sodium-glucose cotransporter-2 (SGLT-2) inhibitors, dipeptidyl peptidase-4 (DPP-4) inhibitors, and glucagon-like peptide-1receptor (GLP-1R) agonists) using a cohort of patients with incident diabetes derived from the Alberta Tomorrow Project (ATP) database. A retrospective cohort was created from the ATP database using administrative data from October 1, 2000, to March 31, 2021. We examined the effect of anti-hyperglycemic medications including metformin (as a control), SGLT-2 inhibitors, DPP-4 inhibitors, and GLP-1R agonists on a composite kidney outcome including chronic kidney disease, kidney failure, dialysis, kidney transplant, and kidney-related death using a Cox-regression analysis.The study included 3001 patients with an incident diagnosis of diabetes. The average follow-up was 6.7 ± 4.6 years after diagnosis, and 628 (20.9%) patients reached the composite outcome with a mean of 5.6 ± 4.2 years to the first event. A total of 1749 (58.8%) patients were on metformin, 360 (12.0%) on SGLT-2 inhibitors, 313 (10.4%) on DPP-4 inhibitors, and 188 (6.3%) on GLP-1R agonists. Only the patients prescribed SGLT-2 inhibitors had a significant reduction in the composite outcome (hazard ratio (HR) 0.23, 95% CI 0.09-0.62, P-value = .003), and a dose-related effect was observed. Our study has shown that SGLT-2 inhibitors result in significant reduction of composite kidney outcomes, including chronic kidney disease, suggesting a renally protective effect over long term.

Newer diabetes medications may have beneficial effects on mortality, cardiovascular outcomes, and renal outcomes. To evaluate the effectiveness, comparative effectiveness, and harms of sodium-glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP1) agonists, dipeptidyl peptidase-4 (DPP4) inhibitors, and long-acting insulins as monotherapy or combination therapy in adults with type 2 diabetes mellitus (T2DM). MEDLINE and EMBASE for randomized controlled trials (RCTs) published from 2010 through January 2023. RCTs lasting at least 52 weeks that included at least 500 adults with T2DM receiving eligible medications and reported any outcomes of interest. Data were abstracted by 1 reviewer and verified by a second. Independent, dual assessments of risk of bias and certainty of evidence (CoE) were done. A total of 130 publications from 84 RCTs were identified. CoE was appraised using GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria for direct, indirect, and network meta-analysis (NMA); the highest CoE was reported. Compared with usual care, SGLT2 inhibitors and GLP1 agonists reduce all-cause mortality (high CoE) and major adverse cardiovascular events (MACE) (moderate to high CoE), SGLT2 inhibitors reduce progression of chronic kidney disease (CKD) and heart failure hospitalizations and GLP1 agonists reduce stroke (high CoE), and SGLT2 inhibitors reduce serious adverse events and severe hypoglycemia (high CoE). The threshold for minimally important differences, which was predefined with the American College of Physicians Clinical Guidelines Committee, was not met for these outcomes. Compared with usual care, insulin, tirzepatide, and DPP4 inhibitors do not reduce all-cause mortality (low to high CoE). Compared with insulin, SGLT2 inhibitors and GLP1 agonists reduce all-cause mortality (low to moderate CoE). Compared with DPP4 inhibitors, GLP1 agonists reduce all-cause mortality (moderate CoE). Compared with DPP4 inhibitors and sulfonylurea (SU), SGLT2 inhibitors reduce MACE (moderate to high CoE). Compared with SU and insulin, SGLT2 inhibitors and GLP1 agonists reduce severe hypoglycemia (low to high CoE). Infrequent direct comparisons between drugs of interest; sparse data for NMA on most outcomes; possible incoherence due to differences in baseline patient characteristics and usual care; insufficient data on predefined subgroups, including demographic subgroups, patients with prior cardiovascular disease, and treatment-naive persons. In adults with T2DM, SGLT2 inhibitors and GLP1 agonists (but not DPP4 inhibitors, insulin, or tirzepatide) reduce all-cause mortality and MACE compared with usual care. SGLT2 inhibitors reduce CKD progression and heart failure hospitalization and GLP1 agonists reduce stroke compared with usual care. Serious adverse events and severe hypoglycemia are less frequent with SGLT2 inhibitors and GLP1 agonists than with insulin or SU. American College of Physicians. (PROSPERO: CRD42022322129).
