The relationship between use of SGLT2is and incidence of respiratory and infectious diseases and site-specific fractures: a meta-analysis based on 32 large RCTs. Eur J Clin Pharmacol 2024; 80:563-573. [PMID: 38267688 DOI: 10.1007/s00228-024-03631-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 01/17/2024] [Indexed: 01/26/2024]
Abstract
OBJECTIVES We aimed to evaluate the relationship between use of sodium-glucose cotransporter-2 inhibitors (SGLT2is) and incidence of various respiratory and infectious diseases and site-specific fractures. METHODS Large randomized controlled trials (RCTs) of SGLT2is enrolling more than 400 subjects were included. Outcomes of interest were various serious adverse events regarding to respiratory and infectious disorders and site-specific fractures. Meta-analysis was done using risk ratio (RR) and 95% confidence interval (CI) as effect size. RESULTS Thirty-two large RCTs were included in this meta-analysis. Use of SGLT2is was significantly associated with the lower incidences of 6 kinds of noninfectious respiratory diseases {e.g., Asthma (RR 0.64, 95% CI 0.43-0.96; P = 0.0299), Chronic obstructive pulmonary disease [COPD] (RR 0.75, 95% CI 0.62-0.91; P = 0.0027), and Respiratory failure (RR 0.78, 95% CI 0.61-0.99; P = 0.0447)} and 4 kinds of infectious respiratory diseases {e.g., Bronchitis (RR 0.61, 95% CI 0.46-0.81; P = 0.0007), and Pneumonia (RR 0.85, 95% CI 0.78-0.93; P = 0.0002)}. Use of SGLT2is was not significantly associated with the incidences of 31 kinds of site-specific fractures (e.g., Hip fracture, Femoral neck fracture, and Spinal fracture; P > 0.05). CONCLUSIONS Our meta-analysis confirmed the benefits of SGLT2is against 6 kinds of noninfectious respiratory diseases (e.g., Asthma, COPD, and Respiratory failure) and 4 kinds of infectious respiratory diseases (e.g., Bronchitis, and Pneumonia). These findings suggest a likelihood that SGLT2is might be used to prevent or treat these respiratory diseases. Moreover, our meta-analysis for the first time revealed no association between use of SGLT2is and incidence of various site-specific fractures.

Comparison of Effectiveness Among Different Sodium-Glucose Cotransoporter-2 Inhibitors According to Underlying Conditions: A Network Meta-Analysis of Randomized Controlled Trials. J Am Heart Assoc 2024; 13:e031805. [PMID: 38293914 PMCID: PMC11056162 DOI: 10.1161/jaha.123.031805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Accepted: 12/27/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND To investigate the individual profile of each SGLT2 (sodium-glucose cotransoporter-2) inhibitor in patients with different backgrounds. METHODS AND RESULTS This study included 21 placebo-controlled randomized controlled trials with a total of 96 196 participants, investigating empagliflozin, ertugliflozin, dapagliflozin, canagliflozin, and sotagliflozin. The primary efficacy end point was the composite of cardiovascular death and hospitalizations for heart failure. The secondary efficacy end points were all-cause death, cardiovascular death, hospitalizations for heart failure, kidney disease progression, and acute kidney injury. We conducted subgroup analyses based on the underlying comorbidities, including diabetes and chronic kidney disease. Safety end points were also assessed among SGLT2 inhibitors in the overall cohort. In the overall cohort, there were no significant differences in the primary efficacy outcome among the SGLT2 inhibitors, while empagliflozin (hazard ratio [HR], 0.70 [95% CI, 0.53-0.92]) and dapagliflozin (HR, 0.73 [95% CI, 0.56-0.96]) were associated with lower risk of acute kidney injury than sotagliflozin. The presence or absence of diabetes did not alter the results. In patients with chronic kidney disease, there were no differences in the efficacy outcomes among SGLT2 inhibitors, while in patients without chronic kidney disease, empagliflozin was associated with lower risk of the primary outcome compared with ertugliflozin (HR, 0.77 [95% CI, 0.60-0.98]). For safety outcomes, no significant differences were observed in amputation, urinary tract infection, genital infection, hypoglycemia, and diabetic ketoacidosis. CONCLUSIONS The differences in reducing cardiovascular and kidney outcomes as well as safety profiles across SGLT2 inhibitors were not consistently significant, although empagliflozin might be preferred in patients without chronic kidney disease. Further investigations are needed to better understand the mechanism and clinical effectiveness of each SGLT2 inhibitor in certain populations.

Inclusion of Middle Eastern and North African populations in diabetes clinical research. J Natl Med Assoc 2023; 115:454-458.

Abstract
The need for diverse representation in clinical trials has recently been reinforced by the Food and Drug Administration's (FDA) guidance for industry entitled, "Diversity Plans to Improve Enrollment of Participants from Underrepresented Racial and Ethnic Populations in Clinical Trials." By ensuring inclusion of underrepresented racial and ethnic minority populations in clinical trials, results can be more generalizable and the safety and efficacy can be accurately assessed within the diverse U.S. population. Limitations exist in the interpretation and implementation of clinical trial results reported using the current racial and ethnic categories, as these standards do not reflect the true diversity of the U.S. population. This is particularly true for the Middle Eastern and North African (MENA) population, which is usually overlooked given the lack of an established category. Although the international MENA region demonstrates the highest prevalence of diabetes in the world at 12.2%, the actual prevalence among MENA individuals living in the U.S. may be "hidden" within the White category. Therefore, data on the MENA population should be disaggregated from data within the White category to not only unmask health disparities, but also to ensure adequate representation in clinical trials. This paper discusses the importance of appropriate representation and inclusion of the MENA population in diabetes clinical trials, which is a critical public health issue domestically and globally.

Effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors on serum urate levels in patients with and without diabetes: a systematic review and meta-regression of 43 randomized controlled trials. Ther Adv Chronic Dis 2022; 13:20406223221083509. [PMID: 35342538 PMCID: PMC8949773 DOI: 10.1177/20406223221083509] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 02/08/2022] [Indexed: 01/10/2023] Open
Abstract
Objectives Sodium-glucose cotransporter-2 (SGLT2) inhibitors have been found to reduce serum urate in patients with type 2 diabetes mellitus. To evaluate if this effect applies to both patients with and without diabetes, we conducted a systematic review and meta-analysis of SGLT2 inhibitors on serum urate levels in this population. Methods Four electronic databases (PubMed, Embase, Cochrane and SCOPUS) were searched on 25 September 2021 for articles published from 1 January 2000 up to 25 September 2021, for studies that examined the effect of SGLT2 inhibitors on serum urate in study subjects. Random-effects meta-analysis was performed, with subgroup analyses on the type of SGLT2 inhibitor agent administered, presence of type 2 diabetes mellitus, presence of chronic kidney disease and drug dose. Results A total of 43 randomized controlled trials, with a combined cohort of 31,921 patients, were included. Both patients with [-31.48 μmol/L; 95% confidence interval (CI): -37.35 to -25.60] and without diabetes (-91.38 μmol/L; 95% CI: -126.53 to -56.24) on SGLT2 inhibitors had significantly lower urate levels when compared with placebo. This treatment effect was similarly observed across different types of SGLT2 inhibitors. However, in type 2 diabetes mellitus (T2DM) patients with chronic kidney disease, the reduction in serum urate with SGLT2 inhibitors became insignificant (95% CI: -22.17 to 5.94, p < 0.01). Conclusion This study demonstrated that SGLT2 inhibitors are beneficial in reducing serum urate in patients with and without diabetes. SGLT2 inhibitors could therefore contribute to the general treatment of hyperuricaemia.

Effects of dapagliflozin in the progression of atherosclerosis in patients with type 2 diabetes: a meta-analysis of randomized controlled trials. Diabetol Metab Syndr 2022; 14:41. [PMID: 35272683 PMCID: PMC8908556 DOI: 10.1186/s13098-022-00810-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 02/23/2022] [Indexed: 02/07/2023] Open
Abstract
AIMS At present, an increasing number of studies are trying to determine whether dapagliflozin has a significant effect on the occurrence and development of atherosclerosis in patients with type 2 diabetes mellitus (T2DM), but there is no consensus. In addition, the former meta-analyses, relying on only a few previous studies and a minimal number of research indicators, have not been able to draw sufficient conclusions simultaneously. Consequently, we conducted a meta-analysis to evaluate the effectiveness of dapagliflozin in the occurrence and development of atherosclerosis in patients with T2DM. METHODS We searched electronic databases (PubMed, Embase, Cochrane, and Scopus) and reference lists in relevant papers for articles published in 2011-2021. We selected studies that evaluated the effects of dapagliflozin on the risk factors related to the occurrence or development of atherosclerosis in patients with T2DM. A fixed or random-effect model calculated the weighted average difference of dapagliflozin on efficacy, and the factors affecting heterogeneity were determined by Meta-regression analysis. RESULTS Twelve randomized controlled trials (18,758 patients) were incorporated in our meta-analysis. In contrast with placebo, dapagliflozin was associated with a significantly increase in high density lipoprotein-cholesterol (HDL-C) [MD = 1.39; 95% CI (0.77, 2.01); P < 0.0001], Δflow-mediated vasodilatation (ΔFMD) [MD = 1.22; 95% CI (0.38, 2.06); P = 0.005] and estimated Glomerular Filtration Rate(eGFR) [MD = 1.94; 95% CI (1.38, 2.51); P < 0.00001]. Furthermore, dapagliflozin had a tremendous advantage in controlling triglycerides (TG) in subgroups whose baseline eGFR < 83 ml/min/1.73m2 [MD = - 10.38; 95% CI (- 13.15, - 7.60); P < 0.00001], systolic blood pressure (SBP) [MD = - 2.82; 95% CI (- 3.22, - 2.42); P < 0.00001], HbA1c, BMI, body weight and waist circumference. However, dapagliflozin has an adverse effect on increasing total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C). Besides, there were no significant changes in other indicators, including adiponectin and C-peptide immunoreactivity. CONCLUSIONS Our pooled analysis suggested that dapagliflozin has a terrifically better influence over HDL-C, ΔFMD, and eGFR, and it concurrently had a tremendous advantage in controlling TG, SBP, DBP, HbA1c, BMI, body weight, and waist circumference, but it also harms increasing TC and LDL-C. Furthermore, this study found that the effect of dapagliflozin that decreases plasma levels of TG is only apparent in subgroups of baseline eGFR < 83 ml/min/1.73m2, while the subgroup of baseline eGFR ≥ 83 ml/min/1.73m2 does not. Finally, the above results summarize that dapagliflozin could be a therapeutic option for the progression of atherosclerosis in patients with T2DM.

Effects of sodium-glucose cotransporter 2 inhibitors on serum uric acid in patients with type 2 diabetes mellitus: A systematic review and network meta-analysis. Diabetes Obes Metab 2022; 24:228-238. [PMID: 34617381 DOI: 10.1111/dom.14570] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 10/02/2021] [Accepted: 10/03/2021] [Indexed: 12/13/2022]
Abstract
AIMS The present study aims to determine the effects of sodium-glucose cotransporter 2 (SGLT-2) inhibitors on the serum uric acid (SUA) levels of patients with type 2 diabetes mellitus (T2DM) in Asia. METHODS PubMed, CENTRAL, Embase and Cochrane Library databases were searched for randomized controlled trials of SGLT-2 inhibitors in patients with T2DM up to 15 July 2021, without language or date restrictions. RESULTS In total, 19 high-quality studies (4218 participants) were included in the present network meta-analysis. All of the included SGLT-2 inhibitors (empagliflozin, dapagliflozin, canagliflozin, ipragliflozin, luseogliflozin and tofogliflozin) significantly decreased SUA levels compared with those of the control [total standard mean difference -0.965, 95% CI (-1.029, -0.901), p = .000, I2 = 98.7%] in patients with T2DM. Subgroup analysis and meta-regression showed that the combined analysis of different inhibitors might lead to heterogeneity of the results. Therefore, among the SGLT-2 inhibitors, the results of the subsequent network meta-analysis revealed that luseogliflozin and dapagliflozin ranked the highest in terms of lowering SUA levels among the SGLT-2 inhibitors. Moreover, the network meta-analysis declared that luseogliflozin (1 and 10 mg) and dapagliflozin (5 mg) led to a superior reduction in SUA in patients with T2DM. CONCLUSIONS SGLT-2 inhibitors could significantly reduce SUA levels in patients with T2DM, particularly luseogliflozin (1 and 10 mg) and dapagliflozin (5 mg) possess the best effects. Therefore, SGLT-2 inhibitors look extremely promising as an antidiabetes treatment option in patients with T2DM with high SUA.

Effects of Dapagliflozin Adjunct to Insulin on Glycemic Variations in Patients with Newly Diagnosed Type 2 Diabetes: A Randomized, Controlled, Open-Labeled Trial. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6618257. [PMID: 34497852 PMCID: PMC8419509 DOI: 10.1155/2021/6618257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 08/10/2021] [Indexed: 01/10/2023]
Abstract
Background This study is aimed at investigating whether dapagliflozin adjunct to insulin therapy further improves glycemic control compared to insulin therapy alone in patients with newly diagnosed type 2 diabetes (T2D). Methods This single-centre, randomized, controlled, open-labeled trial recruited newly diagnosed T2D patients. Subjects were randomized 1 : 1 to the dapagliflozin add-on to continuous subcutaneous insulin infusion (CSII) group (DAPA) or the CSII therapy group for 5 weeks. Standard meal tests were performed 3 times at days -3, 7, and 35 for glucose, C-peptide, and insulin level determination. Two-time continuous glucose monitoring (CGM) was performed at baseline and at the end of the study. The primary endpoint was the difference in the mean amplitude of glycemic excursions (MAGEs) between the groups. Results A total of 66 subjects completed the study, with 34 and 32 patients in the DAPA and CSII groups, respectively. Patients in the DAPA group exhibited significant decreases in MAGE levels at the endpoint. We also observed that patients in the DAPA group had a lower homoeostasis model assessment insulin resistance (HOMA-IR) and a higher homoeostasis model assessment B (HOMA-B) value at 1 week and 5 weeks compared to those with insulin therapy, respectively. In addition, our data showed that patients in the DAPA group showed a significantly lower insulin dose (0.07 U/kg) and weighed less than those in the CSII group. Conclusion Our data indicate that dapagliflozin adjunct to insulin is a safe and effective therapy for improving glycemic variations, insulin sensitivity, and weight loss in newly diagnosed T2D patients.

Role of Folic Acid Drugs in the Treatment with Antithrombotic and Anticoagulant Drugs for Patients with Cardiovascular Diseases Based on the Analysis of Virtual Reality Medical Data. JOURNAL OF HEALTHCARE ENGINEERING 2021; 2021:9914787. [PMID: 34394899 PMCID: PMC8360729 DOI: 10.1155/2021/9914787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 05/23/2021] [Accepted: 06/13/2021] [Indexed: 11/17/2022]
Abstract
In recent years, with the continuous progress and development of science and technology and the increasing maturity of medical technology, the incidence of cardiovascular diseases has gradually increased with the age of the population. In the case of cardiovascular disease, proper anticoagulant therapy can effectively prevent bleeding in the occurrence of events, so a more effective treatment of cardiovascular disease is considered a difficult problem to overcome. Therefore, this article proposes the role of folic acid drugs based on virtual reality medical data analysis in the treatment of cardiovascular disease patients with antithrombotic and anticoagulant drugs, in order to improve providing help for cardiovascular disease. This study selected patients with cardiovascular disease who were admitted to the hospital and extracted 100 patients with complete data and a one-year follow-up period, covering the overall status of the patients' cardiovascular risk factors, cardiovascular disease degree, and the occurrence of major cardiovascular adverse events. During the follow-up period, we analyzed the specific status of major cardiovascular adverse events and the occurrence of bleeding events and compared and analyzed the effects of folic acid drugs on the treatment with antithrombotic and anticoagulant drugs in patients with cardiovascular disease. Experiments have proved that the differences in the degree of cardiovascular stenosis and the number of cardiovascular disease vessels in the four groups are statistically significant (P < 0.01). The degree of cardiovascular stenosis in group D was lighter than that in groups A, B, and C, and the number of cardiovascular lesions was also less than that in groups A, B, and C. The differences were statistically significant (P < 0.05). This indicates that folic acid can effectively treat cardiovascular stenosis, prevent cardiovascular disease, and then treat patients with cardiovascular disease with antithrombotic and anticoagulant drugs. It provides an important basis for accurate clinical diagnosis and treatment.

Abstract
Aims/Introduction To investigate the clinical outcomes of patients with type 2 diabetes mellitus (T2DM) who initiated dapagliflozin in real-world practice in Taiwan. Materials and Methods In this multicenter retrospective study, adult patients with T2DM who initiated dapagliflozin after May 1st 2016 either as add-on or switch therapy were included. Changes in clinical and laboratory parameters were evaluated at 3 and 6 months. Baseline factors associated with dapagliflozin response in glycated hemoglobin (HbA1c) were analyzed by univariate and multivariate logistic regression. Results A total of 1,960 patients were eligible. At 6 months, significant changes were observed: HbA1c by −0.73% (95% confidence interval [CI] −0.80, −0.67), body weight was -1.61 kg (95% CI −1.79, −1.42), and systolic/diastolic blood pressure by −3.6/−1.4 mmHg. Add-on dapagliflozin showed significantly greater HbA1c reduction (−0.82%) than switched therapy (−0.66%) (p = 0.002). The proportion of patients achieving HbA1c <7% target increased from 6% at baseline to 19% at Month 6. Almost 80% of patients experienced at least 1% reduction in HbA1c, and 65% of patients showed both weight loss and reduction in HbA1c. Around 37% of patients had at least 3% weight loss. Multivariate logistic regression analysis indicated patients with higher baseline HbA1c and those who initiated dapagliflozin as add-on therapy were associated with a greater reduction in HbA1c. Conclusions In this real-world study with the highest patient number of Chinese population to date, the use of dapagliflozin was associated with significant improvement in glycemic control, body weight, and blood pressure in patients with T2DM. Initiating dapagliflozin as add-on therapy showed better glycemic control than as switch therapy.

Abstract
OBJECTIVE To evaluate the effects of drug interventions that may modify the progression of chronic kidney disease (CKD) in adults with CKD stages 3 and 4. DESIGN Systematic review and meta-analysis. METHODS Searching MEDLINE, EMBASE, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, International Clinical Trials Registry Platform, Health Technology Assessment, Science Citation Index, Social Sciences Citation Index, Conference Proceedings Citation Index and Clinical Trials Register, from March 1999 to July 2018, we identified randomised controlled trials (RCTs) of drugs for hypertension, lipid modification, glycaemic control and sodium bicarbonate, compared with placebo, no drug or a drug from another class, in ≥40 adults with CKD stages 3 and/or 4, with at least 2 years of follow-up and reporting renal function (primary outcome), proteinuria, adverse events, maintenance dialysis, transplantation, cardiovascular events, cardiovascular mortality or all-cause mortality. Two reviewers independently screened citations and extracted data. For continuous outcomes, we used the ratio of means (ROM) at the end of the trial in random-effects meta-analyses. We assessed methodological quality with the Cochrane Risk of Bias Tool and confidence in the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. RESULTS We included 35 RCTs and over 51 000 patients. Data were limited, and heterogeneity varied. Final renal function (estimated glomerular filtration rate) was 6% higher in those taking glycaemic control drugs (ROM 1.06, 95% CI 1.02 to 1.10, I2=0%, low GRADE confidence) and 4% higher in those taking lipid-modifying drugs (ROM 1.04, 95% CI 1.00 to 1.08, I2=88%, very low GRADE confidence). For RCTs of antihypertensive drugs, there were no significant differences in renal function. Treatment with lipid-modifying drugs led to a 36% reduction in cardiovascular disease and 26% reduction in all-cause mortality. CONCLUSIONS Glycaemic control and lipid-modifying drugs may slow the progression of CKD, but we found no pooled evidence of benefit nor harm from antihypertensive drugs. However, given the data limitations, further research is needed to confirm these findings. PROSPERO REGISTRATION NUMBER CRD42015017501.

Abstract
Dapagliflozin (Forxiga®) is a highly potent, reversible and selective sodium-glucose cotransporter-2 inhibitor indicated worldwide for the treatment of type 2 diabetes (T2D). In the EU, oral dapagliflozin once daily is approved for use as monotherapy (in patients who are intolerant of metformin) and as add-on combination therapy (with other glucose-lowering agents, including insulin) for T2D when diet and exercise alone do not provide adequate glycaemic control. In numerous well-designed clinical studies and their extensions, dapagliflozin as monotherapy and combination therapy with other antihyperglycaemic agents provided effective glycaemic control and reduced bodyweight and blood pressure (BP) across a broad spectrum of patients. Dapagliflozin reduced the rate of cardiovascular (CV) death or hospitalization for heart failure (HHF), did not adversely affect major adverse CV events (MACE) and possibly reduced progression of renal disease relative to placebo in patients with established atherosclerotic CV disease (CVD) or multiple risk factors for CVD. Dapagliflozin was generally well tolerated, with a low risk of hypoglycaemia; diabetic ketoacidosis (DKA), although rare, and genital infections were more common with dapagliflozin than placebo. Given its antihyperglycaemic, cardioprotective and possibly renoprotective properties and generally favourable tolerability profile, dapagliflozin provides an important option for the management of a broad patient population, regardless of the history of CVD.

Abstract
Treatment intended to lower cardiovascular (CV) risk in patients with diabetes has always been a primary goal of diabetes treatment. Due to the subdued effects of reducing hemoglobin A1c (HbA1c) on macrovascular complications, controlling other CV risk factors such as hypertension and hyperlipidemia instead of hyperglycemia has been the mainstay treatment to improve CV outcome in patients with type 2 diabetes mellitus (T2DM) until recent years. This review is intended to summarize and compare the results from the available cardiovascular outcome trials (CVOTs) for the two classes of glucose lowering drug: sodium-glucose co-transporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1 RA). The results including the EMPA-REG, CANVAS program and DECLARE-TIMI 58 trials for SGLT2i, and the ELIXA, LEADER, SUSTAIN-6, EXSCEL and HARMONY trials for GLP-1 RA were summarized. The potential mechanisms of these CV beneficial effects and the optimal CV risk reduction treatment in patients with T2DM based on patient risk stratification and evidence from these CVOTs in real-world setting were discussed.

Abstract
Type 2 diabetes mellitus (T2DM), the leading type of diabetes, has a typical association with coronary heart disease. In India, patients with diabetes are at an increased risk of developing coronary disease as compared to people without diabetes and this suggests the requirement of intensive treatment of cardiovascular (CV) risk factors. Consequently, there is a need for an intervention that could target CV risk factors in multiple paths beyond hyperglycemic control alone. Although metformin is the mainstay of treatment in most of the patients with T2DM, a second line of treatment with anti-hyperglycemic agent is warranted in patients with T2DM in the management of CV risk factors beyond glycemic control. Sodium glucose co-transporter-2 (SGLT-2) inhibitors, the oral hypoglycemic drug, that act independent of insulin secretion are associated with a reduced risk of hypoglycemia which is associated with the increased risk of CV events. Moreover, it has been observed that the use of SGLT-2 inhibitors in patients with T2DM is associated with reductions in blood pressure and body weight beyond improved glycemic control. In this article, the clinical efficacy, safety, and tolerability of SGLT-2 inhibitors on glycemic, nonglycemic parameters, and CV outcome including data from the EMPA-REG OUTCOME study are discussed. The EMPA-REG OUTCOME study is the first CV outcome study that demonstrated the association of a glucose lowering agent with the reduced CV mortality and all-cause mortality, and reduced hospitalization for heart failure in patients with T2DM at high risk of CV events. Although the mode of action associated with the CV benefits remains unknown, data from ongoing trials including DECLARE-TIMI (Dapagliflozin Effect on CV Events) and CANVAS (Canagliflozin CV Assessment Study) trials potentially can validate the class-effect for SGLT-2 inhibitors regarding the CV outcomes.

Abstract
Cardiovascular (CV) disease remains the leading cause of morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM). However, conventional antihyperglycemic medications seem to have minimal effect on lowering CV risk despite achieving excellent reductions in glycated hemoglobin A1c and associated reductions in microvascular risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as noteworthy antihyperglycemic agents with concomitant CV and renal protection in T2DM patients. In this comprehensive review, we present the key CV findings from major large-scale outcome trials of SGLT2 inhibitors to date. We also review the mechanistic studies that might explain the CV benefits of SGLT2 inhibition in patients with T2DM.

Effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on serum uric acid level: A meta-analysis of randomized controlled trials. Diabetes Obes Metab 2018; 20:458-462. [PMID: 28846182 DOI: 10.1111/dom.13101] [Citation(s) in RCA: 206] [Impact Index Per Article: 34.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Revised: 08/10/2017] [Accepted: 08/19/2017] [Indexed: 12/11/2022]
Abstract
The aim of this study was to describe the effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors on serum uric acid (SUA) in patients with type 2 diabetes mellitus (T2DM). PubMed, CENTRAL, EMBASE and ClinicalTrials.gov were searched for randomized controlled trials of SGLT2 inhibitors in patients with T2DM up to May 20, 2017. A total of 62 studies, comprising 34 941 patients, were included. Any of the SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin, tofogliflozin, luseogliflozin or ipragliflozin) significantly decreased SUA levels compared with control (total weighted mean difference [WMD] -37.73 μmol/L, 95% CI [-40.51, -34.95]). Treatment with empagliflozin resulted in a superior reduction in SUA (WMD -45.83 μmol/L, 95% CI [-53.03, -38.63]). The effect persisted during long-term treatment. Dapagliflozin decreased SUA in a dose-dependent manner (from 5 to 50 mg, P = .014). In subgroup analyses, greater reductions could be observed during the course of early diabetes and the SUA-lowering effect was abolished in patients with chronic kidney disease (estimated glomerular filtration rate <60 mL/min per 1.73 m2 ). The effect of SGLT2 inhibitors on SUA reduction suggests that this class of drugs might be beneficial for diabetic patients with hyperuricaemia.

Abstract
Type 2 diabetes (T2DM) is a leading cause of morbidity and mortality worldwide and a major economic burden. The prevalence of T2DM is rising, suggesting more effective prevention and treatment strategies are necessary. The aim of this narrative review is to summarize the pharmacologic treatment options available for patients with T2DM. Each therapeutic class is presented in detail, outlining medication effects, side effects, glycemic control, effect on weight, indications and contraindications, and use in selected populations (heart failure, renal insufficiency, obesity and the elderly). We also present representative cost for each antidiabetic category. Then, we provide an individualized guide for initiation and intensification of treatment and discuss the considerations and rationale for an individualized glycemic goal.

Abstract
Sodium-glucose co-transporter 2 inhibitors (SGLT2is) such as dapagliflozin, canagliflozin, and empagliflozin, are a promising new therapy in the treatment of type 2 diabetes mellitus (T2DM). SGLT2is can effectively reduce hyperglycemia thus improving glycemic control and they offer some beneficial effects on the cardiovascular (CV) system which can benefit patients with heart failure in addition toT2DM. The United States Food and Drug Administration requires new diabetes mellitus therapies to show a CV safety profile. Empagliflozin was the first SGLT2i that, when added to the standard of care for patients withT2DM at high risk for CV events, showed improved CV outcomes including reduced deaths from CV causes. Evidence also exists in favor of dapagliflozin for use in patients with T2DM with CV risk factors and heart failure. This review focuses on the effects, safety, and benefits of dapagliflozin on the CV system. Clinical trials have shown that dapagliflozin improves glycemic control without variation. It is safe and well-tolerated in the general population including older patients and those with high-risk CV factors or preexisting CV disease. There may be a renal protective role by an unknown mechanism. Dapagliflozin also lowers blood pressure due to its natriuresis effect. It improves levels of visceral fat and reduces body weight, and thus ameliorates metabolic syndrome. Dapagliflozin reduces oxidative stress and may delay atherosclerosis. Recent findings indicate SGLT2is may also reduce the atrial natriuretic peptide levels. Additional trials are required to validate these benefits and further evaluate if these are class effects. Trials such as DECLARE-TIMI58 are ongoing to evaluate the CV outcomes of dapagliflozin. More research is needed to design better antihyperglycemic regimes with clinical benefits in addition to good glycemic control.

Abstract
BACKGROUND Due to the chronic nature of type 2 diabetes (T2D), it is essential for an anti-diabetic drug to have durable efficacy and a good long-term safety profile. Dapagliflozin is a member of a unique class of anti-diabetic drugs that inhibit the sodium-glucose cotransporter 2 (SGLT-2) in the renal tubules and have an insulin-independent mechanism of action. In short-term studies (≤ 24 weeks), dapagliflozin reduced glycated hemoglobin (A1c), weight, and systolic blood pressure, and had a good safety profile. METHODS This review summarizes the findings of long-term studies that evaluated the efficacy and safety of dapagliflozin. RESULTS These findings indicate that dapagliflozin is effective as monotherapy and in combination with other anti-hyperglycemic agents, including insulin and oral anti-diabetic therapies, in improving glycemic control and reducing blood pressure and weight for up to 4 years. The findings were fairly consistent across various patient populations with T2D, including those with cardiovascular disease (CVD) and mild renal impairment. Extended use of dapagliflozin was not associated with an increase in safety signals over time. Frequently observed adverse events (AEs) were consistent with the drug's mechanism of action and were generally mild in intensity. No substantial impact of dapagliflozin on renal function was observed, and findings show that the drug is safe in T2D patients with CVD or mild renal impairment, as well as elderly patients. CONCLUSIONS The findings across the studies support the use of dapagliflozin for the long-term treatment of T2D across a broad spectrum of patients.

Abstract
INTRODUCTION The present review developed a clinical consensus based on a Delphi method on Dapagliflozin, a selective inhibitor of the renal sodium-glucose co-transporter-2 (SGLT2-I) in the treatment of patients with Type 2 diabetes mellitus. Areas covered: Panel members, using a 5-point scale, were asked to rate 9 statements on pharmakodinamic, mode of action on glycaemic and extra-glycaemic effects, and safety of dapaglifozin, Members also aimed to identify the patient most susceptible to the treatment with dapagliflozin . Expert commentary: Dapagliflozin is effective in lowering the plasma glucose concentration with a good safety profile. Dapagliflozin can be utilized in combination with all other antihyperglycaemic agents at all stages of the disease: however, a reduced GFR limits its efficacy. As for the other drugs of the class, Dapagliflozin positively modifies other risk factors for CV disease: these effects will be tested in the so far largest cardiovascular outcome trial for the SGLT2 inhibitors so far, the DECLARE trial, which will communicate whether this class of drugs will be disease-modifier in patients with type 2 diabetes also in primary prevention.

Abstract
INTRODUCTION Diabetic kidney disease is the leading cause of end-stage renal disease, a significant contributor to cardiovascular (CV) disease, responsible for much of the morbidity and mortality in patients with type 2 diabetes (T2DM). Strategies to slow or prevent the onset and progression of diabetic kidney disease are critical for effectively managing T2DM and reducing CV risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors are effective antidiabetic agents, which may provide nephroprotective and CV protective effects. Areas covered: This review examines the role of the kidney in glucose homeostasis, discusses renal hemodynamic changes in diabetes, and outlines the major hypotheses regarding the mechanisms underlying renal injury in diabetes. The potential benefits of SGLT2 inhibitors in the prevention and treatment of CV complications in patients with T2DM are reviewed, with particular focus on dapagliflozin. Expert opinion: Dapagliflozin and other SGLT2 inhibitors have the capacity to decrease hyperglycemia and visceral fat, components of the metabolic syndrome particularly associated with the progression of CV disease. However, the mechanisms of action of SGLT2 inhibitors resulting in their positive CV effects remain unclear. Furthermore, the mechanism of action of SGLT2 inhibitors on heart function in non-diabetic patients with decompensated heart failure remains to be explored.

Abstract
Objectives. To observe changes in blood glycemic variations and oxidative stress level before and after dapagliflozin treatment in patients with newly diagnosed T2DM. Methods. This was a randomized, double-blind, placebo-controlled, phase 3 trial. A total of 28 patients with newly diagnosed T2DM with HbA1c levels of 7.5-10.5% were randomly selected to receive dapagliflozin or placebo treatment for 24 weeks. After baseline data were collected, we analyzed glycemic variations and plasma 8-iso PGF2α level at baseline and at the endpoint. Primary outcome was the changes of mean amplitude glycemic excursion (MAGE) within groups. Results. After 24-week dapagliflozin therapy, our data showed the significant improvement of MAGE with dapagliflozin therapy (P = 0.010). Compared with control group, patients in dapagliflozin group exhibited reduction in 24-hour MBG (P = 0.026) and lower mean plasma glucose concentrations, especially during periods from 2400 to 0200 and 1300 to 1800 (P < 0.05, resp.). In addition, plasma 8-iso PGF2α level was notably decreased in the treatment group compared to the control group (P = 0.034). Conclusions. In conclusion, this study shows the ability of dapagliflozin to improve glycemic variations and associate with reduction of oxidative stress in patients with T2DM, which may benefit the cardiovascular system.
