Association between SGLT2 inhibitors and reporting of phimosis/paraphimosis: a comparative pharmacovigilance analysis of the WHO database.

PURPOSE: Recent data have discussed occurrence of phimosis with Sodium-glucose co-transporter-2 (SGLT2) inhibitors. However, the potential risk among the different SGLT2 inhibitors is unknown. METHODS: Using Individual Case Safety Reports (ICSRs) registered in the WHO pharmacovigilance database (01/01/2000-30/06/2025), comparisons between the different SGLT2 inhibitors and versus other drugs used in diabetes (DUD) were performed. Results are shown as Reporting Odds Ratios (ROR). RESULTS: Among 11 342 810 ICSRs, 227 were phimosis/paraphimosis with SGLT2 inhibitors, mainly between 45 and 64 years. The higher ROR value was found with empagliflozin followed by dapagliflozin and canagliflozin. ROR for SGLT2 inhibitors was higher that of all other DUD [34.72 (25.86-46.62)]. The reporting risk of phimosis/paraphimosis with SGLT2 inhibitors was also higher than that of each pharmacological class of DUD. CONCLUSION: The results suggest an association between SGLT2 inhibitors use and phimosis ICSRs. Empagliflozin had the higher reporting risk.

Ketoacidosis with SGLT2 inhibitors in routine clinical practice of type 2 diabetes: Scandinavian cohort and nested case-control study.

BACKGROUND: SGLT2 inhibitors increase the risk of ketoacidosis, but data from routine clinical practice are scarce. We used nationwide registers with the aim of assessing the incidence, risk factors, and prognosis of ketoacidosis during SGLT2 inhibitor treatment in patients with type 2 diabetes. METHODS: In this cohort and nested case-control study we used data from three Scandinavian countries. In a cohort of SGLT2 inhibitor-treatment episodes among patients with type 2 diabetes aged at least 18 years in Sweden, Denmark, and Norway, we estimated ketoacidosis incidence. Using a nested case-control design (matched on age, sex, region of birth, calendar time, and time since treatment initiation), we assessed risk factors and precipitating or co-occurring events. Changes in diabetes medications were evaluated. FINDINGS: The study period was Jan 1, 2013, to Dec 31, 2021, in Denmark and Sweden, and Jan 1, 2013, to Dec 31, 2022, in Norway. We included 322 597 treatment episodes among 282 282 patients with type 2 diabetes (mean age 63 years, 116 521 [36·1%] of 322 597 women). During a median (IQR) follow-up of 1·3 (0·7-2·8) years, 1452 ketoacidosis events occurred (incidence 2·43 per 1000 person-years). Although highest shortly after initiation, risk persisted throughout follow-up. Strong risk factors included high HbA1c (≥83 vs ≤52 mmol/mol: odds ratio [OR] 15·37 [95% CI 11·50-20·53]), malnutrition (OR 10·54 [7·32-15·18]), previous ketoacidosis (OR 10·40 [7·09-15·24]), low BMI (<20 kg/m2vs 20 to <25 kg/m2: OR 9·98 [5·68-17·53]), and recent hypoglycaemia (OR 5·22 [2·60-10·49]). Infection was the most common precipitating or co-occurring event (454 [31·8%] of 1428 vs 862 [6·1%] of 14 233 for ketoacidosis cases vs controls; OR 7·60 [6·62-8·71]). The strongest associations were observed for alcohol intoxication, acute renal events, acute abdomen, stroke, and major surgery, although associations for some transient exposures, particularly milder conditions, might have been overestimated because of under-registration among controls. Exploratory analyses suggested that the observed associations were largely general to patients with type 2 diabetes rather than specific to SGLT2 inhibitor use. At 1 year after ketoacidosis, 211 (25·1%) of 842 remained on SGLT2 inhibitors and insulin use increased from 269 (31·9%) of 842 to 615 (73·0%) of 842. INTERPRETATION: Ketoacidosis risk with SGLT2 inhibitors varies greatly by patient characteristics and is not confined to early in treatment. Risk should be assessed throughout treatment, and patients should be instructed to pause treatment during acute illness and stress.

Effect of SGLT2 inhibitor drugs on triglyceride-glucose (TyG) index in adults: A systematic review and meta-analysis.

BACKGROUND: Insulin resistance is a serious public health concern. The triglyceride-glucose (TyG) index is a simple, cheap, and reproducible surrogate of insulin resistance, and sodium-glucose cotransporter-2 (SGLT2) inhibitors have reshaped cardio-metabolic care beyond glycemic control. METHODS: We followed PRISMA and registered the protocol in PROSPERO (CRD420251056341). We searched PubMed, Scopus, Web of Science, EMBASE, and Cochrane from inception to May 31st, 2026, including observational studies and clinical trials reporting baseline and follow-up TyG in adults. Two reviewers screened records, a third resolved disagreements, data were extracted with a standardized form, and quality was assessed with Cochrane RoB 2.0, the Newcastle-Ottawa Scale, and the JBI checklists. The primary outcome was within-group change in TyG pooled with random-effects (Hartung-Knapp); tests were two-sided with a significance threshold of 0.05. RESULTS: Twelve studies comprising thirteen study arms were included, with a total of 1845 participants. Follow-up ranged from 12 weeks to 5 years. Across studies, SGLT2 inhibitor therapy was associated with a significant reduction in TyG index (mean difference = -0.28, 95% confidence interval [-0.41; -0.14], I2 = 99.5%). Egger's test suggested possible small-study effects, whereas Begg's test and trim-and-fill analysis did not show clear evidence of publication bias; leave-one-out analyses showed that no single study materially influenced the pooled estimate. CONCLUSION: Despite heterogeneity in populations, drug choice, and follow-up duration, SGLT2 inhibitors were associated with a significant decrease in TyG, although small-study effects cannot be excluded.

Glycemic and Renal Effects of SGLT2 Inhibitors in Monogenic Diabetes: A Real-World National Study.

AIMS: Evidence regarding the efficacy and safety of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in monogenic diabetes is limited. We evaluated real-world metabolic, renal, and safety outcomes of SGLT2i therapy in adults with monogenic diabetes. MATERIALS AND METHODS: This multicenter retrospective study included adults with genetically confirmed monogenic diabetes treated with SGLT2i. Clinical and biological data were collected at baseline and after approximately 1 and 2 years. Longitudinal changes were analysed using linear mixed-effects models adjusted for baseline value, age, and sex and treatment intensification. RESULTS: Forty patients (mean age 48.6 ± 15.2 years) with MIDD (n = 16), HNF1B-MODY (n = 9), HNF1A/HNF4A-MODY (n = 11), or other MODY subtypes (ABCC8, INS, RFX6; n = 4) were followed for 23.9 ± 5.9 months. HbA1c remained stable overall but decreased significantly in patients with baseline HbA1c ≥ 8% (9.6% ± 1.3% to 7.6% ± 0.7%; p = 0.001). UACR declined significantly (-35.6% at 1 year and -43.5% at 2 years; p = 0.004), particularly in those with baseline CKD (trend). Genotype-specific trends suggested greater glycemic improvement in HNF1A/HNF4A-MODY and greater UACR reduction in MIDD. eGFR declined modestly over time. Non-serious adverse events occurred in 15% of patients, 7.5% discontinued treatment, and no ketoacidosis, acute kidney injury, or deaths were reported. CONCLUSIONS: In this nationwide cohort of patients with monogenic diabetes-the largest reported to date-SGLT2i therapy was associated with improved glycemic control in individuals with baseline HbA1c ≥ 8%, reduced albuminuria, and showed a favourable safety profile. These findings support SGLT2i as a potential therapeutic option that warrants confirmation in larger controlled studies.

Estimated Lifetime Cardiovascular, Kidney, and Mortality Benefits of Combination Treatment With SGLT2 Inhibitors, GLP-1 Receptor Agonists, and Nonsteroidal MRA Compared With Conventional Care in Patients With Type 2 Diabetes and Albuminuria.

BACKGROUND: Sodium glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and the nonsteroidal mineralocorticoid receptor antagonist (ns-MRA) finerenone all individually reduce cardiovascular, kidney, and mortality outcomes in patients with type 2 diabetes and albuminuria. However, the lifetime benefits of combination therapy with these medicines are not known. METHODS: We used data from 2 SGLT2i trials (CANVAS [Canagliflozin Cardiovascular Assessment] and CREDENCE [Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation]), 2 ns-MRA trials (FIDELIO-DKD [Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease] and FIGARO-DKD [Efficacy and Safety of Finerenone in Subjects With Type 2 Diabetes Mellitus and the Clinical Diagnosis of Diabetic Kidney Disease]), and 8 GLP-1 RA trials to estimate the relative effects of combination therapy versus conventional care (renin-angiotensin system blockade and traditional risk factor control) on cardiovascular, kidney, and mortality outcomes. Using actuarial methods, we then estimated absolute risk reductions with combination SGLT2i, GLP-1 RA, and ns-MRA in patients with type 2 diabetes and at least moderately increased albuminuria (urinary albumin:creatinine ratio ≥30 mg/g) by applying estimated combination treatment effects to participants receiving conventional care in CANVAS and CREDENCE. RESULTS: Compared with conventional care, the combination of SGLT2i, GLP-1 RA, and ns-MRA was associated with a hazard ratio of 0.65 (95% CI, 0.55-0.76) for major adverse cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death). The corresponding estimated absolute risk reduction over 3 years was 4.4% (95% CI, 3.0-5.7), with a number needed to treat of 23 (95% CI, 18-33). For a 50-year-old patient commencing combination therapy, estimated major adverse cardiovascular event-free survival was 21.1 years compared with 17.9 years for conventional care (3.2 years gained [95% CI, 2.1-4.3]). There were also projected gains in survival free from hospitalized heart failure (3.2 years [95% CI, 2.4-4.0]), chronic kidney disease progression (5.5 years [95% CI, 4.0-6.7]), cardiovascular death (2.2 years [95% CI, 1.2-3.0]), and all-cause death (2.4 years [95% CI, 1.4-3.4]). Attenuated but clinically relevant gains in event-free survival were observed in analyses assuming 50% additive effects of combination therapy, including for major adverse cardiovascular events (2.4 years [95% CI, 1.1-3.5]), chronic kidney disease progression (4.5 years [95% CI, 2.8-5.9]), and all-cause death (1.8 years [95% CI, 0.7-2.8]). CONCLUSIONS: In patients with type 2 diabetes and at least moderately increased albuminuria, combination treatment of SGLT2i, GLP-1 RA, and ns-MRA has the potential to afford relevant gains in cardiovascular and kidney event-free and overall survival.

Efficacy of sodium-glucose cotransporter 2 inhibitors after acute myocardial infarction: Are the benefits limited to patients with diabetes? A systematic review and meta-analysis.

BACKGROUND: Acute myocardial infarction remains one of the leading causes of death worldwide. Recently, studies have focused on evaluating the effectiveness of SGLT2 inhibitors in this scenario. Objectives We aimed to perform a meta-analysis comparing the efficacy of SGLT2 inhibitors vs standard care. METHODS: We systematically searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs) and observational studies comparing patients with acute myocardial infarction using iSGLT2 inhibitors and standard care. Statistical analyses were conducted using R software (v 4.3.2) and a random-effects model was employed for all outcomes. RESULTS: A total of 31,378 patients were included, with 10,897 (34.7%) assigned to the SGLT2 inhibitor group. Among these studies, three were randomized controlled trials (RCTs). There was a significant difference in reduction of HF readmissions (OR 0.61; p < 0.01), all-cause mortality (OR 0.62; p < 0.01;) and stroke (OR 0.67; p < 0.01;). However, there was no significant difference in cardiovascular death, rehospitalization for any cause and recurrence of acute MI. Meta regression and subgroup analysis showed a trend toward better outcomes in the diabetic and non-STEMI population. CONCLUSIONS: SGLT2 inhibitors were associated with lower HF rehospitalization, stroke, and all-cause mortality after acute MI, mainly in observational studies. Benefits appeared greater in diabetic and non-STEMI patients. Dedicated RCTs focusing on diabetic, particularly non-STEMI, populations are needed to confirm these findings. KEY POINTS: What is already known on this topic: SGLT2 inhibitors have demonstrated cardiovascular and renal benefits in patients with heart failure and type 2 diabetes mellitus. However, their role in the acute myocardial infarction (AMI) setting remains uncertain, particularly regarding post-AMI outcomes such as heart failure readmissions, mortality, and recurrent ischemic events, with current evidence derived from heterogeneous and predominantly observational studies. WHAT THIS STUDY ADDS: This meta-analysis, including over 31,000 patients, suggests that SGLT2 inhibitors are associated with reductions in heart failure readmissions, all-cause mortality, and stroke following AMI. These associations were more consistently observed in patients with type 2 diabetes and in non-ST-segment elevation myocardial infarction (NSTEMI) populations. However, randomized controlled trials showed neutral results, and the observed benefits were mainly driven by observational studies. Meaning: These findings should be interpreted as hypothesis-generating. While SGLT2 inhibitors may represent a potential therapeutic strategy in selected post-AMI populations, particularly patients with diabetes and NSTEMI, current evidence does not support routine early in-hospital initiation. Dedicated randomized trials specifically enrolling diabetic post-AMI patients are required to clarify optimal timing and clinical benefit.

Sodium-glucose cotransporter-2 inhibitors and gastrointestinal neoplasm risk in type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials.

The potential carcinogenic effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus (T2DM) remain controversial, particularly regarding site-specific gastrointestinal (GI) neoplasms. This systematic review and meta-analysis aimed to determine the relationship between SGLT2 inhibitors and the risk of GI neoplasms in patients with T2DM. We searched PubMed, EMBASE, Cochrane CENTRAL, Scopus, and Web of Science through March 17, 2025, for RCTs in T2DM comparing SGLT2 inhibitors with placebo or active comparators. Two reviewers independently screened studies, extracted data, and assessed the risk of bias. The primary outcome was GI neoplasms reported in publications, supplementary materials, or trial registries, usually as adverse events rather than centrally adjudicated cancer endpoints. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated in Stata 17.0. In 48 RCTs (n = 48,765), SGLT2 inhibitor therapy was not associated with overall GI neoplasm risk (OR = 1.10, 95% CI: 0.84-1.44; p = 0.46; I² = 0%). Site-specific analyses showed no statistically significant association for esophageal (OR = 1.12, 95% CI 0.37-3.45), gastric (1.20, 0.65-2.23), hepatic (0.62, 0.31-1.22), pancreatic (0.91, 0.51-1.64), colonic (1.28, 0.78-2.08), colorectal (0.76, 0.27-2.17), and rectal neoplasms (0.98, 0.49-1.97), with all p-values > 0.05. Subgroup analyses by agents (e.g., canagliflozin, dapagliflozin, empagliflozin), baseline age, body mass index (BMI), HbA1c, treatment duration, and dose were also non-significant (all p > 0.05). Approximately half of the trials had follow-up of one year or less, limiting our ability to evaluate long-term risk. Available RCT evidence does not show a clear increase in GI neoplasm risk with SGLT2 inhibitors in T2DM. However, limited follow-up, low event counts, and non-cancer-specific outcome ascertainment, the findings should be interpreted as reassuring but not definitive evidence of long-term oncologic safety.Systematic review registration: PROSPERO No. CRD42024619019.

Safety and outcomes of dapagliflozin initiation in critically ill patients with acute kidney injury: A post-hoc analysis of the defender trial.

BACKGROUND: SGLT2 inhibitor use in acute kidney injury (AKI) is controversial due to concerns about hemodynamic instability. We evaluated dapagliflozin initiation in critically ill patients with AKI enrolled in the DEFENDER trial. METHODS: Among 212 patients with AKI at enrollment (100 dapagliflozin, 112 control), we compared 28-day mortality, kidney replacement therapy (KRT), and composite death/KRT. Adjusted risk differences were estimated controlling for age, sepsis, baseline vasopressor use, and creatinine. Physiological trajectories (creatinine, urine output, fluid balance, acid-base parameters) over days 1-5 were analyzed using mixed models. Likelihood ratios quantified compatibility with clinically meaningful harm or benefit. RESULTS: Event rates were similar: 28-day mortality 38% vs 40%, KRT 12% vs 18%, composite 41% vs 42% (dapagliflozin vs control). Adjusted risk differences were - 1.9% (95% CI -14.5 to 10.7) for death, -7.4% (-16.2 to 1.5) for KRT, and - 0.9% (-13.6 to 11.8) for the composite. Physiological trajectories showed no divergence suggestive of hemodynamic or metabolic instability. Likelihood ratios provided limited separation: at 5% absolute effect threshold, LR against harm was 1.47 and against benefit 1.19. CONCLUSIONS: Dapagliflozin initiation in critically ill patients with AKI was not associated with excess mortality, KRT, or physiological derangement. The near-neutral evidential profile indicates neither moderate harm nor benefit can be excluded, supporting feasibility of dedicated trials of SGLT2 inhibitors in AKI.

Large-scale AI analysis reveals missed opportunities in albuminuria testing and disease-modifying therapy implementation.

AIMS: Albuminuria is a key diagnostic and prognostic biomarker of chronic kidney disease (CKD), associated with adverse cardiovascular and renal outcomes. Despite guideline recommendations, urine albumin-to-creatinine ratio (UACR) testing is infrequently performed in cardiology. This study assessed the uptake of UACR testing, the estimated prevalence of undiagnosed albuminuria, and the use of disease-modifying therapies in patients with cardio-kidney-metabolic (CKM) disease. METHODS AND RESULTS: We conducted a retrospective cohort study of all adults seen at the cardiology department of a tertiary referral centre between 2019 and 2024. Data were extracted using CTcue, an AI-driven platform. Albuminuria was defined as UACR ≥30 mg/g. A weighted logistic regression model estimated albuminuria prevalence in untested patients. Among 77 351 patients (44.8% female, mean age 64.4 years), only 8.9% had a recorded UACR, of whom 46.4% had albuminuria. Testing rates were low across high-risk groups: 29.9% in diabetes, 21.7% in heart failure, and 13.7% in hypertension. In untested patients, the predicted prevalence of albuminuria was 36.6%, and highest in those with eGFR <30 mL/min/1.73m2 (70.0%), heart failure (47.8%), or diabetes (46.8%). Use of disease-modifying therapies was low, even among patients with confirmed albuminuria. In patients with documented vs. predicted albuminuria, 43.0% vs. 39.1% received renin-angiotensin system inhibitors, 12.8% vs. 5.7% received SGLT2 inhibitors, and <1% in both groups received finerenone. CONCLUSION: Albuminuria is substantially underdetected in cardiology practice, possibly contributing to underuse of effective CKM therapies. Systematic UACR screening with structured treatment protocols may help close this gap and improve outcomes for patients with CKM disease.

Cardiovascular Drug Access in Australia and New Zealand: New PBS and PHARMAC Listings, 2023-2025.

BACKGROUND: Cardiovascular disease is a leading cause of death in Australia and New Zealand. Publicly subsidised access to new cardiovascular medications is governed by the PBS (Pharmaceutical Benefits Scheme) in Australia and PHARMAC (Pharmaceutical Management Agency) in New Zealand, yet no consolidated resource catalogues recent listings across both jurisdictions. METHODS: We reviewed all new cardiovascular drug listings and indications on the PBS and PHARMAC schedules from 1 January 2023 to 31 December 2025. PBS data were obtained from the PBS Pricing and Policy Branch through the Cardiac Society for Australia and New Zealand. PHARMAC data were obtained via direct communication with PHARMAC and cross-referenced with public schedule information. Pivotal trial evidence, restriction criteria, and prescribing considerations were extracted from published literature and regulatory documents. RESULTS: Five new cardiovascular drugs were PBS-listed (inclisiran, mavacamten, tafamidis, icosapent ethyl and migalastat), two existing drugs received new cardiovascular indications (empagliflozin and dapagliflozin for heart failure with preserved ejection fraction) and prasugrel was relisted for acute coronary syndrome. One major change occurred on the PHARMAC schedule (empagliflozin for heart failure with reduced ejection fraction). CONCLUSIONS: The 2023-2025 period has seen notable additions to cardiovascular pharmacotherapy in Australia, including the first cardiac myosin inhibitor, the first transthyretin stabiliser, expanded lipid lowering therapy options, and extension of SGLT2 inhibitor coverage across the heart failure ejection fraction spectrum. A pronounced access disparity persists between Australia and New Zealand.

Glucosamine links hyperglycemia to mTORC1 activation and glucose toxicity in diabetes.

Hyperglycemia is a principal driver of β cell failure and multiple-organ complications in diabetes. Chronic exposure to hyperglycemia overstimulates mTORC1, disrupting glucose metabolism and promoting ER stress, oxidative stress, and inflammation; however, the upstream metabolic signal(s) linking glucose to mTORC1 activation remains unclear. Here, we identified glucosamine as a key metabolite connecting elevated glucose to mTORC1 signaling in pancreatic islets and kidney, both major targets of hyperglycemic damage. Using 13C6-glucose metabolic labeling in diabetic rodents treated with or without the SGLT2 inhibitor dapagliflozin or insulin, combined with targeted metabolomics and metabolic flux analysis, we found that tissue glucose concentrations strongly correlated with glucosamine. A similar correlation with plasma glucose was conserved in humans with or without type 2 diabetes, and inversely associated with β cell function. In vitro, low-dose glucosamine stimulated mTORC1 in islets and kidney proximal tubule cells in an O-GlcNAcylation-dependent manner. Broad phosphoproteomics and transcriptomics analyses in β cells showed that glucosamine activated mTORC1-regulating pathways, induced oxidative stress, ER stress, and dedifferentiation. Genetic inhibition of β cell mTORC1 via heterozygous Raptor knockout, as well as pharmacologic inhibition of the glucosamine/mTORC1 axis through SGLT2 inhibition, alleviated β cell stress, improved glycemic control, and restored β cell function. These findings identified the glucosamine/mTORC1 pathway as an important mediator of β cell and kidney dysfunction in diabetes.

Effect of levothyroxine therapy on albuminuria and glomerular function in patients with type 2 diabetes and subclinical Hypothyroidism: a randomized controlled pilot trial.

AIMS: To evaluate the effect of levothyroxine therapy on renal outcomes in patients with type 2 diabetes mellitus (T2DM) and subclinical hypothyroidism (SCH) with background SGLT2 inhibitor therapy. METHODS: In this hypothesis generating open-label, randomized controlled pilot trial, adults with T2DM and SCH were assigned (1:1) to levothyroxine or no levothyroxine therapy and followed for 6 months. Primary outcomes were changes in urinary albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR). RESULTS: Sixty participants were randomized (30 per group); 24 and 27 completed follow-up in the treatment and control groups respectively. UACR decreased with levothyroxine (-13.09 mg/g) and increased in controls (31.84 mg/g). The difference was significant in per-protocol (PP)(-44.93 mg/g; 95% CI -77.6 to -12.26; p = 0.008) but insignificant in intention to treat (ITT)(-35.61 mg/g; 95% CI -77.31 to 6.08; p = 0.092). eGFR changes were statistically insignificant in both ITT(4.65 mL/min/1.73 m2; 95% CI -8.3 to 17.6; p = 0.472) and PP(7.35 mL/min/1.73 m2; 95% CI -1.68 to 16.37; p = 0.108). Thyroid-stimulating hormone decreased significantly in treatment arm in comparison to control arm (p < 0.001) in ITT and PP. No adverse event was reported. CONCLUSIONS: Levothyroxine treatment showed trend toward improving albuminuria and eGFR without reaching statistical significance, suggesting possible renoprotective effect warranting further studies. CLINICAL TRIAL REGISTRATION: This trial is registered with Clinical Trial Registry of India (CTRI/2025/06/089606).

Insulin, Semaglutide and Dapagliflozin in Adults With Type 1 Diabetes: Design and Methods of Triple Therapy for Type 1 Diabetes (TTT1)-An International Phase 3 Clinical Trial.

AIMS: Attaining target glycaemia can be a challenge in Type 1 Diabetes (T1D) due to insulin-induced weight gain. Adjunct therapy with modern glucose-lowering agents developed for type 2 diabetes (T2D) has great potential but may be insufficiently efficacious and carries risks of hypoglycaemia and ketosis. We designed the first Phase 3 clinical trial to assess the efficacy and safety of adding a Glucagon-Like Peptide 1 receptor agonist (GLP-1RA) and a Sodium-Glucose Co-transporter (SGLT2) Inhibitor to insulin therapy in overweight and obese adults with T1D and glycaemia above target (HbA1c 7.5%-11.0% inclusive) (NCT03899402). MATERIALS AND METHODS: In Period 1, participants are randomized 2:1 (open label) for 26 weeks to semaglutide and insulin (uptitrated to 1.0 mg weekly) or standard insulin therapy. In Period 2, those randomized to semaglutide and insulin in Period 1 are further randomized (double-blind) for 26 weeks to dapagliflozin (10 mg daily) or placebo, in addition to semaglutide. The primary objective is to compare change in HbA1c on 'triple therapy' (dapagliflozin, semaglutide and insulin) with 'dual therapy' (placebo, semaglutide and insulin). Secondary objectives include comparisons of triple therapy with standard insulin therapy and dual therapy (semaglutide and insulin) with standard insulin therapy. Safety outcomes include hypoglycaemia and ketosis. A sample size recalculation during the trial based on analysis of masked data revised the original recruitment target from 114 to 82 participants. CONCLUSION: The TTT1 trial will provide clinically useful information on combination adjunct therapy in the treatment of T1D.

Efficacy of dapagliflozin on hepatic steatosis and fibrosis in patients with type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease: a pre-specified single-arm analysis from a randomized controlled trial.

AIM: To evaluate the association of dapagliflozin therapy with changes in hepatic steatosis and non-invasive fibrosis surrogate markers in patients with type 2 diabetes mellitus (T2DM) and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) over 12 months. METHODS: This is a pre-specified single-arm analysis from a randomised, open-label, parallel-group trial. Of 54 participants randomised to dapagliflozin 10 mg daily, 50 (92.6%) completed the 12-month follow-up and were included in the per-protocol analysis. Assessments at baseline, 3, 6, and 12 months included transient elastography (CAP and LSM), ultrasonography, and biochemical tests. Primary endpoints were changes in hepatic steatosis (CAP) and non-invasive fibrosis surrogates (LSM). RESULTS: Significant reductions were observed in hepatic steatosis (CAP: 316.7 to 245.7 dB/m; mean change - 71.02 dB/m, 95% CI: -63.4 to - 78.6; p < 0.001) and in liver stiffness as a non-invasive fibrosis surrogate (LSM: 8.59 to 7.28 kPa; mean change - 1.31 kPa, 95% CI: -0.92 to - 1.70; p < 0.001). Improvements were also observed in glycaemic control, body weight, lipid profile, liver enzymes, ultrasonographic steatosis grading, and serum fibrosis markers. Genitourinary infections were the most frequently reported adverse events (32%); no serious adverse events were recorded. CONCLUSIONS: Dapagliflozin was associated with significant improvements in hepatic steatosis, non-invasive fibrosis surrogate markers, metabolic parameters, and liver function in T2DM patients with MASLD over 12 months. These findings provide region-specific evidence for an Indian population and support further controlled investigation. However, these findings should be interpreted in light of the pre-specified single-arm design of this analysis, the open-label methodology, relatively small sample size, and the absence of liver biopsy confirmation.

From pathobiology to prescribing in obesity-driven HFpEF: A systematic review and practical therapeutic framework.

Heart failure with preserved ejection fraction (HFpEF) is increasingly driven by obesity and cardiometabolic dysfunction. In this phenotype, the dominant biology extends beyond congestion alone and includes visceral and epicardial adiposity, systemic inflammation, impaired myocardial energetics, endothelial dysfunction, and exertional elevation in filling pressures. We performed a PRISMA-compliant systematic review with structured narrative evidence synthesis to evaluate pharmacological therapy in obesity-driven HFpEF, searching PubMed/MEDLINE, Scopus, Web of Science Core Collection, ClinicalTrials.gov, and WHO ICTRP through December 2025. Eighteen reports were included in the final qualitative synthesis. The available evidence supports sodium-glucose cotransporter 2 inhibitors as the pharmacological foundation because they provide the most mature outcome data across the preserved ejection fraction spectrum. Semaglutide improves symptoms, physical limitations, exercise capacity, and body weight in dedicated obesity-related HFpEF trials, whereas tirzepatide extends this signal by improving clinical status and reducing worsening heart failure events. Finerenone broadens the therapeutic platform in HF with mildly reduced or preserved ejection fraction, although obesity-specific data remain indirect. Conventional neurohormonal therapies retain a selective role, but they are not the principal biological match for this phenotype. Obesity-driven HFpEF should therefore be managed as a cardiometabolic syndrome with heart failure expression, using a phenotype-based sequence that links diagnosis, decongestion, SGLT2 inhibition, obesity-directed therapy, and selective adjunctive intensification.

Dapagliflozin reduces epicardial adipose tissue in patients with heart failure and type 2 diabetes.

BACKGROUND: Epicardial adipose tissue (EAT) has a contributory role in the progression of heart failure. We tested whether dapagliflozin reduces EAT in adults with type 2 diabetes (T2D) and heart failure and explored links with systemic inflammation and cardiac structure. METHODS: This analysis is based on pooled data from two phase 2, single-centre, double-blind, placebo-controlled randomised trials (REFORM and DAPA-LVH) conducted in Scotland. Exactly 122 participants with T2D and stage B or C heart failure were randomised to dapagliflozin 10 mg once daily or placebo for 12 months. Cardiac magnetic resonance imaging (CMR) was used to assess EAT. At baseline and follow-up, the inflammatory markers TNF, IL-1, IL-6, IL-10, and CRP were measured. RESULTS: At baseline, obesity was common (75% with BMI ≥30 kg/m2) and heart-failure phenotypes were balanced (HFpEF 51%, HFrEF 49%). After 12 months, dapagliflozin significantly reduced EAT independently of changes in BMI (-1.16 ± 0.18 vs. +0.36 ± 0.19 cm2, p < 0.001), BMI (-1.17 ± 0.16 vs. -0.18 ± 0.17 kg/m2, p < 0.001), and left ventricular mass (-3.53 ± 1.77 vs. +1.57 ± 1.83 g, p = 0.048) compared with placebo. CONCLUSION: Dapagliflozin shrinks EAT and LV mass independently of BMI in T2D patients with stage B/C heart failure, supporting EAT as a modifiable target of SGLT2 inhibition. The absence of parallel changes in systemic inflammation suggests primarily local mechanisms.

Effects of Sodium-Glucose Cotransporter-2 Inhibitors on Modulating Protein-Bound Uremic Toxins and Gut Microbiota in Predialysis CKD Patients: Matched Case-Control Study.

KEY POINTS: A reduction of indoxyl sulfate, p-cresyl sulfate, and several short-chain fatty acids was seen in sodium-glucose cotransporter-2 inhibitor-treated CKD patients. Variations in gut microbiota composition are correlated with levels of gut-derived uremic toxins in sodium-glucose cotransporter-2 inhibitor-treated CKD patients. BACKGROUND: The intricate interplay between CKD and intestinal microbiota has gained increasing attention, with gut dysbiosis being implicated in uremic toxin accumulation and CKD progression. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are now transforming CKD management but pose uncertain effects on shaping gut microbiota. This study aimed to elucidate the effect of SGLT2i on perturbations of gut microbial composition and metabolic responses in patients with CKD. METHODS: Analysis of fecal microbiota and targeted profiling of serum short-chain fatty acids and gut-derived uremic toxins were conducted in a matched case-control study, including 60 patients with CKD (treated: n=30; untreated: n=30) and 30 non-CKD controls. RESULTS: Gut microbial composition differed significantly among the three study groups. Patients with CKD receiving SGLT2i exhibited distinctive taxonomic profiles, such as enrichment of Bacteroides stercoris and Bacteroides coprocola. Surveys of metabolomic profiles revealed a reduction of two uremic solutes, indoxyl sulfate and p-cresyl sulfate (pCS), and several short-chain fatty acids (formic, acetic, propionic, valeric, and 2-methylbutanoic acid) in SGLT2i-treated CKD patients. Co-occurrence analysis demonstrated a set of intestinal microbes that is positively or negatively correlated with the levels of pCS, and the abundance of these pCS-associated intestinal microorganisms was correlated with the levels of indoxyl sulfate and isovaleric acids in the same and opposite direction, respectively. Further functional prediction indicated attenuated pathways related to protein and carbohydrate metabolism. CONCLUSIONS: Treatment with SGLT2i in patients with CKD is associated with distinct gut microbial composition and metabolite profiles, suggesting potential modulation of gut dysbiosis and metabolic pathways. Further studies are warranted to elucidate the clinical implications of these findings in CKD management.
