Safety of sodium-glucose transporter 2 (SGLT-2) inhibitors in patients with type 2 diabetes: a meta-analysis of cohort studies. Front Pharmacol 2023; 14:1275060. [PMID: 37905204 PMCID: PMC10613530 DOI: 10.3389/fphar.2023.1275060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 09/21/2023] [Indexed: 11/02/2023] Open
Abstract
Aims: This study aimed to investigate the association between the use of sodium-glucose transporter 2 inhibitors (SGLT-2i) and the risk of diabetic ketoacidosis (DKA), lower limb amputation (LLA), urinary tract infections (UTI), genital tract infections (GTI), bone fracture, and hypoglycemia in cohort studies. Methods: A systematic search was conducted in the PubMed and Embase databases to identify cohort studies comparing the safety of SGLT-2i versus other glucose-lowering drugs (oGLD) in patients with type 2 diabetes mellitus (T2DM). The quality of the studies was assessed using the Newcastle-Ottawa Scale. Primary endpoints were DKA and LLA, while secondary endpoints included UTI, GTI, bone fracture, and hypoglycemia. Hazard ratios (HR) with 95% confidence intervals (CI) were calculated. Results: A total of 9,911,454 patients from 40 cohort studies were included in the analysis. SGLT-2i use was associated with a higher risk of DKA (HR: 1.21, 95% CI: 1.07-1.38, p = 0.003) and GTI (HR: 2.72, 95% CI: 2.48-2.98, p < 0.01). However, it was not associated with an increased risk of LLA (HR: 1.06, 95% CI: 0.92-1.23, p = 0.42), UTI (HR: 0.99, 95% CI: 0.89-1.10, p = 0.83), or bone fracture (HR: 0.99, 95% CI: 0.94-1.04, p = 0.66). Furthermore, SGLT-2i was associated with a reduced risk of hypoglycemia. Furthermore, compared to dipeptidyl peptidase 4 inhibitors, SGLT-2i as a class and individually was associated with an increased risk of DKA. Canagliflozin specifically increased the risk of LLA (HR: 1.19, 95% CI: 1.04-1.36, p = 0.01). The subgroup analysis suggested that SGLT-2i increased the risk of LLA among patients with a history of cardiovascular disease. Conclusion: SGLT-2i versus oGLD was associated with a similar occurrence of LLA, UTI, and bone fracture. However, SGLT-2i was associated with a higher risk of DKA and GTI than oGLD. These findings provide valuable information on the safety profile of SGLT-2i in patients with T2DM and can help inform clinical decision-making.

Comparative Safety Analysis of Empagliflozin in Type 2 Diabetes Mellitus Patients with Chronic Kidney Disease versus Normal Kidney Function: A Nationwide Cohort Study in Korea. Pharmaceutics 2023; 15:2394. [PMID: 37896154 PMCID: PMC10610004 DOI: 10.3390/pharmaceutics15102394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 09/22/2023] [Accepted: 09/26/2023] [Indexed: 10/29/2023] Open
Abstract
BACKGROUND Empagliflozin has been shown to reduce cardiovascular morbidity and mortality in patients with type 2 diabetes. Various research on its efficacy in patients with chronic kidney disease (CKD) have been actively conducted. So far, few studies have investigated the safety of these adverse effects specifically in Asians with CKD. We aim to address these safety concerns on a patient population of Asian CKD patients using real-world data. METHODS We conducted a retrospective cohort study using health insurance data from the Korean Health Insurance Review & Assessment Service and compared safety outcomes between empagliflozin and sitagliptin in 26,347 CKD patients diagnosed with diabetes. Adverse outcomes, including major adverse cardiac events (MACEs), all-cause mortality, myocardial infarction (MI), stroke, and hospitalization for heart failure (HHF), among others, were assessed. RESULTS Among a 1:1 matched cohort (6170 on empagliflozin, 6170 on sitagliptin), empagliflozin was associated with a significant reduction in MACEs, all-cause mortality, MI, hospitalization for unstable angina, coronary revascularization, HHF, hypoglycemic events, and urinary tract infections, but increased the risk of genital tract infections. No significant changes were observed for transient ischemic attack, acute kidney injury, volume depletion, diabetic ketoacidosis, thromboembolic events, and fractures. CONCLUSIONS The usage of empagliflozin in diabetic CKD patients shows a significant reduction in many adverse outcomes compared to sitagliptin, but with an increased risk of genital tract infections. These findings provide evidence for future clinical decision-making around the use of empagliflozin in Asian CKD patients.

[PMID: 36110539 PMCID: PMC9468970 DOI: 10.3389/fphar.2022.928121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 07/20/2022] [Indexed: 11/13/2022] Open
Abstract
Aims: In countries where a randomized clinical trial (RCT) is difficult to perform, a real-world evidence (RWE) study with a design similar to an RCT may be an option for drug regulatory decision-making. In this study, the objective was to find out to what extent the safety of empagliflozin from the RWE study in Korea is different from the one in RCT by emulating the design of foreign RCT. The outcome covers various safety outcomes including cardiovascular safety. Methods: The EMPA-REG OUTCOME trial (NCT01131676) was selected for comparison. The inclusion/exclusion criteria and follow-up method for the RWE were matched to the comparison RCT. Major adverse cardiovascular events (MACEs) were used as a primary outcome and 15 other outcomes were also included for analysis. Result: We followed 23,126 matched patients with type 2 diabetes mellitus (11,563 empagliflozin users and 11,563 sitagliptin users) for 2.7 years (median). Empagliflozin use was associated with a significantly decreased risk of MACEs [EMPA-REG DUPLICATE RWE: adjusted HR 0.87, 95% confidence interval (CI) 0.79–0.96]. The predefined estimate agreement, regulatory agreement, and standardized difference for RCT duplication were achieved [EMPA-REG OUTCOME RCT: adjusted HR 0.86, 95% (CI) 0.74–0.99]. According to the predefined criteria for 15 outcomes, 10 outcomes were evaluated as good, and three as moderate. Conclusion: Our study results suggest that RWE in one country in comparison with an RCT has the potential for providing evidence for future regulatory decision-making in an environment where RCT could not be performed.

Abstract
Aim: This study aims to investigate the association between the use of dipeptidyl peptidase-4 inhibitors (DPP-4i), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), or sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and the risk of fracture among patients with type 2 diabetes mellitus. Methods: Medline, Embase, Cochrane Library, and Clinical-Trials.gov databases were searched for randomized controlled trials (RCTs). Network meta-analysis was performed for total fracture and a series of secondary outcomes. Results: A total of 177 RCTs (n = 165,081) involving the risk of fracture were identified (a median follow-up of 26 weeks). DPP-4i, GLP-1 RAs, and SGLT-2i did not increase total fracture risk compared with insulin (odds ratio: 0.86, 95% confidence interval: 0.39-1.90; 1.05, 0.54-2.04; 0.88, and 0.39-1.97, respectively), metformin (1.41, 0.48-4.19; 1.72, 0.55-5.38; 1.44, 0.48-4.30), sulfonylureas (0.77, 0.50-1.20; 0.94, 0.55-1.62; 0.79, 0.48-1.31), thiazolidinediones (0.82, 0.27-2.44; 1.00, 0.32-3.10; 0.83, 0.27-2.57), α-glucosidase inhibitor (4.92, 0.23-103.83; 5.99, 0.28-130.37; 5.01, 0.23-107.48), and placebo (1.04, 0.84-1.29; 1.27, 0.88-1.83; 1.06, 0.81-1.39). Conclusions: The use of DPP-4i, GLP-1 RAs, or SGLT-2i is unlikely to increase the risk of fracture among type 2 diabetes mellitus patients.

Abstract
BackgroundDiabetes mellitus (DM) have become seriously threatens to human health and life quality worldwide. As a systemic metabolic disease, multiple studies have revealed that DM is related to metabolic bone diseases and always induces higher risk of fracture. In view of this, the links between bone metabolism (BM) and DM (BMDM) have gained much attention and numerous related papers have been published. Nevertheless, no prior studies have yet been performed to analyze the field of BMDM research through bibliometric approach. To fill this knowledge gap, we performed a comprehensive bibliometric analysis of the global scientific publications in this field.MethodsArticles and reviews regarding BMDM published between 2000 and 2021 were obtained from the Web of Science after manually screening. VOSviewer 1.6.16, CiteSpace V 5.8.R3, Bibliometrix, and two online analysis platforms were used to conduct the bibliometric and visualization analyses.ResultsA total of 2,525 documents including 2,255 articles and 270 reviews were retrieved. Our analysis demonstrated a steady increasing trend in the number of publications over the past 22 years (R2 = 0.989). The United States has occupied the leading position with the largest outputs and highest H-index. University of California San Francisco contributed the most publications, and Schwartz AV was the most influential author. Collaboration among institutions from different countries was relatively few. The journals that published the most BMDM-related papers were Bone and Osteoporosis International. Osteoporosis and related fractures are the main bone metabolic diseases of greatest concern in this field. According to co-cited references result, “high glucose environment,” “glycation end-product” and “sodium-glucose co-transporter” have been recognized as the current research focus in this domain. The keywords co-occurrence analysis indicated that “diabetic osteoporosis,” “osteoarthritis,” “fracture risk,” “meta-analysis,” “osteogenic differentiation,” “bone regeneration,” “osteogenesis,” and “trabecular bone score” might remain the research hotspots and frontiers in the near future.ConclusionAs a cross-discipline research field, the links between bone metabolism and diabetes mellitus are attracting increased attention. Osteoporosis and related fractures are the main bone metabolic diseases of greatest concern in this field. These insights may be helpful for clinicians to recognize diabetic osteopenia and provide more attention and support to such patients.

Abstract
Increased fracture risk represents an emerging and severe complication of diabetes. The resulting prolonged immobility and hospitalisations can lead to substantial morbidity and mortality. In type 1 diabetes, bone mass and bone strength are reduced, resulting in up to a five-times greater risk of fractures throughout life. In type 2 diabetes, fracture risk is increased despite a normal bone mass. Conventional dual-energy x-ray absorptiometry might underestimate fracture risk, but can be improved by applying specific adjustments. Bone fragility in diabetes can result from cellular abnormalities, matrix interactions, immune and vascular changes, and musculoskeletal maladaptation to chronic hyperglycaemia. This Review summarises how the bone microenvironment responds to type 1 and type 2 diabetes, and the mechanisms underlying fragility fractures. We describe the value of novel imaging technologies and the clinical utility of biomarkers, and discuss current and future therapeutic approaches that protect bone health in people with diabetes.

Metabol Open 2021; 10:100082. [PMID: 33817616 PMCID: PMC8010211 DOI: 10.1016/j.metop.2021.100082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Accepted: 01/19/2021] [Indexed: 11/16/2022] Open
Abstract
Most guidelines and cardiovascular outcome trials (CVOTs) focus on secondary prevention of cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM). Patients with T2DM without established CVD (eCVD) also form a critical cohort, for whom primary prevention with timely pharmacological and non-pharmacological interventions can effectively prevent or delay the onset of CVD. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have demonstrated a promising role for primary prevention of CVD in CVOTs and real-world studies. The 2019 American College of Cardiology/American Heart Association guidelines on primary prevention of CVD recommend SGLT2i as one of the add-on treatment options to metformin for adults with T2DM and glycated hemoglobin >7% who have cardiovascular (CV) risk factors. The outcomes with maximal response to SGLT2i use in primary prevention are hospitalization for heart failure and chronic kidney disease. The cardiorenal benefits with SGLT2i are attributed to pleiotropic effects on CV risk factors, and interference with glucose and sodium handling in kidneys, independent of their glycemic benefits. Results therefore support a role for SGLT2i not only in patients with T2DM and eCVD but also in patients with T2DM without eCVD. This review examines the evidence for potential role of SGLT2i for primary prevention of CVD in T2DM.

Abstract
INTRODUCTION Sodium-glucose co-transporter 2 inhibitors (SGLT2is) are licensed for the treatment of type 2 diabetes (T2D) and more recently for heart failure with or without diabetes. They have been shown to be safe (from the cardiovascular (CV) perspective) and effective (in terms of glycaemia, and in some cases, in reducing CV events) in extensive randomised controlled trials (RCTs). However, there remain concerns regarding the generalisability of these findings (to those ineligible for RCT participation) and about non-CV safety. For effectiveness, population-based pharmacoepidemiology studies can confirm and extend the findings of RCTs to broader populations and explore safety, for which RCTs are not usually powered, in more detail. METHODS A pre-planned and registered ((International PROSPEctive Register Of Systematic Reviews) PROSPERO registration CRD42019160792) systematic review of population-based studies investigating SGLT2i effectiveness and safety, following Meta-analyses Of Observational Studies in Epidemiology (MOOSE) guidelines was conducted. RESULTS A total of 37 studies were identified (total n = 1,300,184 adults; total follow-up 910,577 person-years; exposures: SGLT2i class, canagliflozin, dapagliflozin and empagliflozin) exploring CV disease (CVD) outcomes, acute kidney injury (AKI), lower limb amputation (LLA), diabetic ketoacidosis (DKA), bone fracture, urinary tract infection (UTI), genital mycotic infection (GMI), hypoglycaemia, pancreatitis and venous thromboembolism. For CV and mortality outcomes, studies confirmed the associated safety of these drugs and correlated closely with the findings from RCTs, which may extend to primary CVD prevention (major adverse cardiovascular events point estimate range (PER) hazard ratio (HR) 0.78-0.94; hospitalised heart failure PER HR 0.48-0.79). For safety outcomes, SGLT2i exposure was not associated with an increased risk of AKI (PER HR 0.40-0.96), fractures (PER HR 0.87-1.11), hypoglycaemia (PER HR 0.76-2.49) or UTI (PER HR 0.72-0.98). There was a signal for increased association for GMIs (PER HR 2.08-3.15), and possibly for LLA (PER HR 0.74-2.79) and DKA (PER HR 0.96-2.14), but with considerable uncertainty. CONCLUSION In T2D, SGLT2is appear safe from the CV perspective and may have associated benefit in primary as well as secondary CVD prevention. For safety, they may be associated with an increased risk of GMI, LLA and DKA, although longer follow-up studies are needed.

Abstract
INTRODUCTION Preclinical, clinical, and population-based studies have provided evidence that anti-diabetic drugs affect bone metabolism and may affect the risk of fracture in diabetic patients. AREAS COVERED An overview of the skeletal effects of anti-diabetic drugs used in type 2 diabetes is provided. Searches on AdisInsight, PubMed, and Medline databases were conducted up to 1st July 2020. The latest evidence from randomized clinical trials and population-based studies on the skeletal safety of the most recent drugs (DPP-4i, GLP-1RA, and SGLT-2i) is provided. EXPERT OPINION Diabetic patients present with a higher risk of fracture for a given bone mineral density suggesting a role of bone quality in the etiology of diabetic fracture. Bone quality is difficult to assess in human clinical practice and the use of preclinical models provides valuable information on diabetic bone alterations. As several links have been established between bone and energy homeostasis, it is interesting to study the safety of anti-diabetic drugs on the skeleton. So far, evidence for the newest molecules suggests a neutral fracture risk, but further studies, especially in different types of patient populations (patients at risk or with history of cardiovascular disease, renal impairment, neuropathy) are required to fully appreciate this matter.

Abstract
The aim of this study is to compare head-to-head the effects of dapagliflozin and liraglutide on bone strength and bone material properties in a pre-clinical model of diabetes-obesity. Combined low-dose streptozotocin and high fat feeding were employed in mice to promote obesity, insulin resistance, and hyperglycaemia. Mice were administered daily for 28 days with saline vehicle, 1 mg/kg dapagliflozin or 25 nmol/kg liraglutide. Bone strength was assessed by three-point bending and nanoindentation. Bone material properties were investigated by Fourier transform infrared microspectroscopy/imaging. Although diabetic controls presented with dramatic reductions in mechanical strength, no deterioration of bone microarchitecture was apparent. At the tissue level, significant alterations in phosphate/amide ratio, carbonate/phosphate ratio, tissue water content, crystal size index, collagen maturity and collagen glycation were observed and linked to alteration of matrix biomechanics. Dapagliflozin and liraglutide failed to improve bone strength by 3-point bending or bone microarchitecture during the 28-day-treatment period. At bone formation site, dapagliflozin enhanced phosphate/amide ratio, mineral maturity, and reduced tissue water content, crystal size index, and collagen glycation. Liraglutide had significant effects on phosphate/amide ratio, tissue water content, crystal size index, mature collagen crosslinks, collagen maturity, and collagen glycation. At bone formation site, both drugs modulated matrix biomechanics. This study highlighted that these two molecules are effective in improving bone material properties and modulating matrix biomechanics at bone formation site. This study also highlighted that the resulting effects on bone material properties are not identical between dapagliflozin and liraglutide and not only mediated by lower blood glucose.

The effect of luseogliflozin on bone microarchitecture in older patients with type 2 diabetes: study protocol for a randomized controlled pilot trial using second-generation, high-resolution, peripheral quantitative computed tomography (HR-pQCT). Trials 2020; 21:379. [PMID: 32370806 PMCID: PMC7201752 DOI: 10.1186/s13063-020-04276-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 03/24/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Older patients with type 2 diabetes mellitus (T2DM) have an increased risk of bone fracture independent of their bone mineral density (BMD), which is explained mainly by the deteriorated bone quality in T2DM compared to that in non-diabetic adults. Sodium-glucose co-transporter (SGLT) 2 inhibitors have been studied in several trials in T2DM, and the Canagliflozin Cardiovascular Assessment Study showed an increased fracture risk related to treatment with the SGLT2 inhibitor canagliflozin, although no evidence of increased fracture risk with treatment with other SGLT2 inhibitors has been reported. The mechanism of the difference in the fracture risk between the SGLT2 inhibitors is unknown, but the differences among the SGLT2 inhibitors in the selectivity of SGLT2 against SGLT1 may affect bone metabolism, since among the SGLT2 inhibitors the selectivity of canagliflozin is lowest. We will investigate whether the SGLT2 inhibitor luseogliflozin, which has the higher SGLT2 selectivity, affects bone metabolism by using high-resolution, peripheral quantitative computed tomography (HR-pQCT) which provides direct in vivo morphometric information about the bone microarchitecture. METHODS/DESIGN This is a single-center, randomized, open-label, active-controlled, parallel pilot trial. Eligible participants are older (age ≥ 60 years) individuals with T2DM with HbA1c levels at 7.0-8.9%. A total of 24 participants will be allocated to either the luseogliflozin group (taking luseogliflozin) or the control group (taking metformin) in a 1:1 ratio to compare the groups' changes in bone microarchitecture of the radius and tibia which are analyzed by HR-pQCT before and at 48 weeks after the administration of each medication. The laboratory data associated with glycemic control and bone metabolism will be collected every 12 weeks during the study. Recruitment began in June 2019. DISCUSSION The reason that we use metformin as an active control is to avoid yielding differences in glycemic control between the luseogliflozin and control groups. Besides, metformin is considered to have a neutral effect on bone. This trial should reveal the effect of luseogliflozin on bone metabolism in older patients with T2DM. TRIAL REGISTRATION The study was registered with the University Hospital Medical Information Network (UMIN000036202) on 1 April 2019 and with the Japan Registry of Clinicla Trials (jRCTs071180061) on 14 March 2019.

Abstract
Purpose of review Sodium glucose cotransporter 2 (SGLT2) inhibitors are relatively novel antidiabetic drugs that improve glycemic control and reduce cardiovascular outcomes as well as renal function decline. SGLT2 inhibitors act by inhibiting glucose reabsorption in the proximal tubule of the kidney. Emerging data suggest that these drugs may also influence bone and mineral metabolism. This review summarizes clinical trial data on bone and mineral outcomes, and discusses potential underlying mechanisms. Recent findings Three large randomized controlled trials documented cardiovascular and renal protective effects of SGLT2 inhibitors. Recent studies indicate that SGLT2 inhibitors influence renal phosphate reabsorption and calciuria. Although the CANVAS trial suggested an increased fracture risk associated with canagliflozin compared with placebo, the vast majority of trials and meta-analyses did not demonstrate an increased fracture risk associated with SGLT2 inhibitor use. Summary SGLT2 inhibitors have shown clinically relevant cardiovascular and renal protective effects. The long-term implications for bone health, in particular in the context of chronic kidney disease, are still incompletely understood and warrant further investigation.

Abstract
Selective sodium-dependent glucose co-transporter 2 inhibitors (SGLT2Is) are oral hypoglycemic medications utilized increasingly in the medical management of hyperglycemia among persons with type 2 diabetes (T2D). Despite favorable effects on cardiovascular events, specific SGLT2Is have been associated with an increased risk for atypical fracture and amputation in subgroups of the T2D population, a population that already has a higher risk for typical fragility fractures than the general population. To better understand the effect of SGLT2 blockade on skeletal integrity, independent of diabetes and its co-morbidities, we utilized the "Jimbee" mouse model of slc5a2 gene mutation to investigate the impact of lifelong SGLT2 loss-of-function on metabolic and skeletal phenotype. Jimbee mice maintained normal glucose homeostasis, but exhibited chronic polyuria, glucosuria and hypercalciuria. The Jimbee mutation negatively impacted appendicular growth of the femur and resulted in lower tissue mineral density of both cortical and trabecular bone of the femur mid-shaft and distal femur metaphysis, respectively. Several components of the Jimbee phenotype were characteristic only of male mice compared with female mice, including reductions: in body weight; in cortical area of the mid-shaft; and in trabecular thickness within the metaphysis. Despite these decrements, the strength of femur diaphysis in bending (cortical bone), which increased with age, and the strength of L6 vertebra in compression (primarily trabecular bone), which decreased with age, were not affected by the mutation. Moreover, the age-related decline in bone toughness was less for Jimbee mice, compared with control mice, such that by 49-50 weeks of age, Jimbee mice had significantly tougher femurs in bending than C57BL/6J mice. These results suggest that chronic blockade of SGLT2 in this model reduces the mineralization of bone but does not reduce its fracture resistance.

Abstract
Diabetes mellitus, with its complications, is one of the major health problems in economically developed countries and its prevalence is constantly increasing. Kidneys and heart involvement represent main comorbidities in diabetic patients often leading to organ failure. The treatments available until a few years ago are often associated with hypoglycemia, weight gain, gastro-intestinal disorders and other side effects together with serious adverse effects on renal function. The new frontiers of diabetic cardionephropathy treatment are mainly focused on delay of heart and renal failure both on diabetic and nondiabetic patients ad it was shown by last data reports. In the following review, we will focus on Gliflozins, one of the newest classes of hypoglycemic drugs that have shown to hold peculiar pharmacological properties in managing cardiac and renal complications.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) have been shown to mitigate the risks of cardiovascular (CV) and renal complications in patients with type 2 diabetes (T2D) and CV risk factors or CV disease (CVD). In CV outcomes trials (CVOTs) of patients with T2D and established CVD or multiple CV risk factors, empagliflozin and canagliflozin were associated with significant reductions in the risks of major adverse CV events (MACE), hospitalization for heart failure (HF) and kidney disease progression. In the DECLARE-TIMI 58 study, in which the majority of patients did not have established CVD, dapagliflozin was associated with significant reductions in the composite end point of CV death or hospitalization for HF and was noninferior to placebo with regard to MACE; although patients had relatively good renal function, dapagliflozin also showed renal benefits similar to those seen with empagliflozin and canagliflozin. This article reviews the increased risk of CVD and renal disease in patients with T2D and discusses the potential mechanisms of the cardioprotective and renoprotective effects of SGLT-2i therapy. The observed improvements in CV and renal outcomes with SGLT-2is in CVOTs suggest a class effect in this patient population and have influenced treatment guidelines for the way add-on therapy to metformin is initiated in patients with T2D and high CV risk. The overall cardioprotective and renoprotective effects of SGLT-2is in patients with T2D and high CV risk are most likely attributable to multiple mechanisms, including cardiac, haemodynamic, metabolic, anti-inflammatory and renal effects.

Abstract
PURPOSE To determine the risk of fractures associated with sodium-glucose co-transporter 2 inhibitors (SGLT2i) compared with dipeptidyl peptidase-4 inhibitors (DPP4i). METHODS We conducted a retrospective cohort study using data from the Truven Health MarketScan (2009-2015) databases. Our cohort included patients newly initiating treatment with SGLT2i or DPP-4i between 1 April 2013 and 31 March 2015 that were matched 1:1 using high dimensional propensity scores. Patients were followed up in an as-treated approach starting from initiation of treatment until the earliest of any fracture, treatment discontinuation, disenrollment, or end of data (31 December 2015). Risk of fractures was determined at any time during the follow-up, early in therapy (1-14 days of the follow-up), and later in therapy (15 days and beyond). Cox proportional hazards models were used to determine hazard ratios and robust 95% confidence intervals (95% CI). RESULTS After matching, our cohort included 30 549 patients in each treatment group. Over a median follow-up of 219 days, there were 745 fractures overall. The most common site for fractures was the foot (32.7%). The effect estimates for fracture risk occurring at any time during follow-up, early in therapy, and later in therapy were HR 1.11 [95% CI 0.96-1.28], HR 1.82 [95% CI 0.99-3.32], and HR 1.07 [95% CI 0.92-1.24], respectively. CONCLUSION There is a possible increase in risk for fractures early in therapy with SGLT2i. Beyond this initial period, SGLT2is had no apparent effect on the incidence of fractures.

Abstract
Type 2 diabetes, one of the most frequent chronic diseases, has an important effect on bone metabolism, with most studies reporting an increased prevalence of fractures in these patients despite an apparently increased bone mineral density. Most probable explanation is an alteration of bone structure/quality with increased fragility but the different diabetes medications influence the risk of fracture. While metformin and incretin-based therapies are safe, thiazolidinediones and canagliflozin (sodium-glucose cotransporter-2 inhibitor) negatively impact bone metabolism and should be avoided in subjects at increased risk of fractures. Insulin and sulphonylureas are generally safe but can increase the risk of hypoglycemia and falls with subsequent traumatic fractures. Their combination should be avoided, especially in elderly subjects.

Abstract
In the present meta-analysis based on real-world data, the use of dipeptidyl peptidase-4 inhibitors (DPP-4i), glucagon-like peptide-1 receptor agonists (GLP-1ra), or sodium-glucose cotransporter-2 inhibitors (SGLT2i) was not associated with the risk of fracture. INTRODUCTION Cumulative evidence from randomized control trials (RCTs) with limited fracture events showed that the use of DPP-4i, GLP-1ra, or SGLT2i may not affect the risk of fracture. However, additional insights from large population-based studies with routinely collected data on fracture events and an adequate amount of fracture events are necessary to draw firm conclusions. To refine and complement the results from RCTs, a systematic review and meta-analysis of observational studies were performed to investigate the association between the use of DPP-4i, GLP-1ra, or SGLT2i and the risk of fracture in real-world settings. METHODS The PubMed and Web of Science databases were searched to identify relevant observational studies. A random-effect model was used to estimate the summary relative risks (RRs). RESULTS The use of DPP-4i (RR 0.83, 95% CI [confidence interval] 0.60, 1.14; n = 11), GLP-1ra (RR 0.65, 95% CI 0.24, 1.74; n = 4), or SGLT2i (RR 1.02, 95% CI 0.91, 1.16; n = 4) was not associated with the risk of fracture. In general, there was a consistent lack of association between the use of DPP-4i or GLP-1ra and the risk of fracture across nearly all subgroups, except for a significantly reduced risk of hip fracture with the use of GLP-1ra (RR 0.21, 95% CI 0.04, 0.98). CONCLUSIONS Cumulative real-world evidence does not support an association between the use of DPP-4i, GLP-1ra, or SGLT2i and the risk of fracture. Our findings, together with the cumulative evidence from RCTs, should reassure policy makers and medical practitioners that the use of these medications is unlikely to increase the risk of fracture among type 2 diabetes mellitus patients in general. Further studies need to investigate the long-term impact of these drugs on the fracture risk, particularly in high-risk populations.

Abstract
Type 2 diabetes (T2D) is associated with an increased risk of macro- and microvascular complications, including cardiovascular disease (CVD), heart failure (HF), and chronic kidney disease (CKD). Of the currently available glucose-lowering therapies, sodium-glucose cotransporter-2 inhibitors (SGLT-2is) are the only class to target the pathophysiologic increase in renal glucose reabsorption in patients with T2D. In CV outcomes trials of SGLT-2is in patients with T2D and established CVD or varying levels of CV risk, empagliflozin, canagliflozin, and dapagliflozin were associated with significant improvements in the risk of composite CV and renal outcomes compared with placebo that extended beyond their glycemic effects. Real-world observational studies have also reported improvements in CV outcomes with SGLT-2is compared with other glucose-lowering therapy in routine clinical practice. This review describes the pleiotropic effects of SGLT-2is and discusses the potential mechanisms for these effects as well as how they potentially provide benefits beyond glycemic control in patients with T2D. These favorable nonglycemic effects indicate that SGLT-2is may be of particular benefit in patients with diabetic complications, such as CVD, HF, or CKD. Ongoing large randomized trials in specific patient populations, including those with CVD, HF, or CKD (with or without T2D), may help to confirm the benefits of SGLT-2is in these patients and further elucidate the potential mechanisms of their pleiotropic effects.

SGLT2 Inhibitors: Nephroprotective Efficacy and Side Effects. ACTA ACUST UNITED AC 2019; 55:medicina55060268. [PMID: 31212638 PMCID: PMC6630922 DOI: 10.3390/medicina55060268] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2019] [Revised: 05/30/2019] [Accepted: 06/06/2019] [Indexed: 02/06/2023]
Abstract
The burden of diabetic kidney disease (DKD) has increased worldwide in the last two decades. Besides the growth of diabetic population, the main contributors to this phenomenon are the absence of novel nephroprotective drugs and the limited efficacy of those currently available, that is, the inhibitors of renin-angiotensin system. Nephroprotection in DKD therefore remains a major unmet need. Three recent trials testing effectiveness of sodium-glucose cotransporter 2 inhibitors (SGLT2-i) have produced great expectations on this therapy by consistently evidencing positive effects on hyperglycemia control, and more importantly, on the cardiovascular outcome of type 2 diabetes mellitus. Notably, these trials also disclosed nephroprotective effects when renal outcomes (glomerular filtration rate and albuminuria) were analyzed as secondary endpoints. On the other hand, the use of SGLT2-i can be potentially associated with some adverse effects. However, the balance between positive and negative effects is in favor of the former. The recent results of Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation Study and of other trials specifically testing these drugs in the population with chronic kidney disease, either diabetic or non-diabetic, do contribute to further improving our knowledge of these antihyperglycemic drugs. Here, we review the current state of the art of SGLT2-i by addressing all aspects of therapy, from the pathophysiological basis to clinical effectiveness.

Abstract
CONTEXT The combination of two beneficial antidiabetes interventions, regular exercise and pharmaceuticals, is intuitively appealing. However, metformin, the most commonly prescribed diabetes medication, attenuates the favorable physiological adaptations to exercise; in turn, exercise may impede the action of metformin. OBJECTIVE We sought to determine the influence of an alternative diabetes treatment, sodium glucose cotransporter 2 (SGLT2) inhibition, on the response to endurance exercise training. DESIGN, PARTICIPANTS, AND INTERVENTION In a randomized, double-blind, repeated measures parallel design, 30 sedentary overweight and obese men and women were assigned to 12 weeks of supervised endurance exercise training, with daily ingestion of either a placebo or SGLT2 inhibitor (dapagliflozin: ≤10 mg/day). OUTCOME MEASUREMENTS AND RESULTS Endurance exercise training favorably modified body mass, body composition (dual-energy x-ray absorptiometry), peak oxygen uptake (graded exercise with indirect calorimetry), responses to standardized submaximal exercise (indirect calorimetry, heart rate, and blood lactate), and skeletal muscle (vastus lateralis) citrate synthase activity (main effects of exercise training, all P < 0.05); SGLT2 inhibition did not influence any of these physiological adaptations (exercise training × treatment interaction, all P > 0.05). However, after endurance exercise training, fasting blood glucose was greater with SGLT2 inhibition, and increased insulin sensitivity (oral glucose tolerance test/Matsuda index) was abrogated with SGLT2 inhibition (exercise training × treatment interaction, P < 0.01). CONCLUSION The efficacy of combining two beneficial antidiabetes interventions, regular endurance exercise and SGLT2 inhibition, was not supported. SGLT2 inhibition blunted endurance exercise training-induced improvements in insulin sensitivity, independent of effects on aerobic fitness or body composition.

Abstract
INTRODUCTION Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are recommended after metformin for a large spectrum of patients with type 2 diabetes, because of a favorable benefit/risk profile despite a variety of adverse events. AREAS COVERED This narrative review discusses the safety profile of SGLT2is: initial concerns (cardiovascular safety, acute renal failure, hypoglycemia, urinary and genital infections, volume depletion, bladder cancer), further concerns (euglycemic ketoacidosis, bone fractures) and more recent concerns (lower limb amputation, Fournier's gangrene). EXPERT OPINION Overall, the safety profile of SGLT2is is good. The only increased adverse event that was consistently reported in clinical trials and observational studies is genital mycotic infections, with only a borderline increase in urinary tract infections. Among clinical trials, only the CANVAS program reported an unexpected increase in bone fractures and peripheral amputations. A variety of rare adverse events have been described as case reports, including ketoacidosis, amputations and Fournier gangrene, which led to specific warnings by regulatory agencies. Identifying predisposing patient's characteristics and/or precipitating clinical conditions would help prevent the most severe complications. These adverse events should not mask the overall cardiovascular and renal benefit of SGLT2is, especially in patients with type 2 diabetes at high cardiovascular risk.

Abstract
Sodium glucose co-transporter 2 inhibitors (SGLT2is) are the first class of glucose lowering agent to be shown to reduce cardiovascular events. They are generally well tolerated with infrequent serious adverse events. The most frequent side effect is genital mycotic infections with candida species that are usually mild to moderate in severity, easily treated and infrequently recur. Urinary tract infections, although common in patients with diabetes, have not been shown to be increased in controlled studies with SGLT2i. Hypoglycaemia can occur when an SGLT2i is added to agents that cause hypoglycaemia, such as insulin or sulphonylureas. Volume depletion and hypotension is infrequent and can be minimized by adjusting diuretic and antihypertensive treatment in patients at risk. Acute renal failure or kidney injury was observed in early observational studies. However, in randomized controlled trials (RCTs) and in more recent observational studies a decreased incidence of acute kidney injury was observed in SGLT2-treated patients compared to those receiving either placebo or another class of glucose lowering agents. An increased incidence of amputation (largely feet and toes) was observed in the RCT with canagliflozin but not with the other SGLT2i. Observational studies have shown either an increased risk of amputation with other agents whereas another study showed no increase. Although the increased risk of amputation is very low, avoidance of SGLT2i in patients at high risk seems prudent. Increased incidence of fractures was observed with canagliflozin but not with SGLT2i nor in a meta-analysis that included canagliflozin, empagliflozin and dapagliflozin. No increased incidence of cancer has been observed in either RCTs or observational studies.

Abstract
Persons with type 1 or type 2 diabetes have a significantly higher fracture risk than age-matched persons without diabetes, attributed to disease-specific deficits in the microarchitecture and material properties of bone tissue. Therefore, independent effects of diabetes drugs on skeletal integrity are vitally important. Studies of incretin-based therapies have shown divergent effects of different agents on fracture risk, including detrimental, beneficial, and neutral effects. The sulfonylurea class of drugs, owing to its hypoglycemic potential, is thought to amplify the risk of fall-related fractures, particularly in the elderly. Other agents such as the biguanides may, in fact, be osteo-anabolic. In contrast, despite similarly expected anabolic properties of insulin, data suggests that insulin pharmacotherapy itself, particularly in type 2 diabetes, may be a risk factor for fracture, negatively associated with determinants of bone quality and bone strength. Finally, sodium-dependent glucose co-transporter 2 inhibitors have been associated with an increased risk of atypical fractures in select populations, and possibly with an increase in lower extremity amputation with specific SGLT2I drugs. The role of skeletal muscle, as a potential mediator and determinant of bone quality, is also a relevant area of exploration. Currently, data regarding the impact of glucose lowering medications on diabetes-related muscle atrophy is more limited, although preclinical studies suggest that various hypoglycemic agents may have either aggravating (sulfonylureas, glinides) or repairing (thiazolidinediones, biguanides, incretins) effects on skeletal muscle atrophy, thereby influencing bone quality. Hence, the therapeutic efficacy of each hypoglycemic agent must also be evaluated in light of its impact, alone or in combination, on musculoskeletal health, when determining an individualized treatment approach. Moreover, the effect of newer medications (potentially seeking expanded clinical indication into the pediatric age range) on the growing skeleton is largely unknown. Herein, we review the available literature regarding effects of diabetes pharmacotherapy, by drug class and/or by clinical indication, on the musculoskeletal health of persons with diabetes.

Abstract
Recent studies showed that in patients with type 2 diabetes mellitus (T2DM), Sodium-dependent glucose transporters 2 inhibitor (SGLT2I) may cause potential adverse effects on the skeleton such as increasing the risk of fracture. This risk is possibly mediated by effects induced by all SGLT2I class drugs, but whether Dapagliflozin aggravates osteoporosis in patients with T2DM remains controversial. Therefore, we designed this study to explore how Dapagliflozin affects the metabolism and the quality of bone in T2DM animal models. The effect of Dapagliflozin on the skeleton was evaluated on male ZDF (Zucker Diabetic Fatty) rats-a rat model of diet induced spontaneous T2DM. Dapagliflozin was administrated via gavage at the dosage of 10 mg/kg/day. Bone tissue mineral density and the microarchitecture of tibiae were measured with micro-CT and biomechanics characteristic of the femora were tested using a three-point bending test. Serum bone biomarkers and other metabolic parameters were also tested via ELISA or other assays. Our results found that diabetic rats demonstrated symptoms of osteoporosis and Dapagliflozin could help to alleviate these defections caused by diabetes. Compared to the negative controls, the serum CT (calcitonin) level in ZDF rats as well as the uric calcium and phosphate levels were elevated, and these symptoms were alleviated by Dapagliflozin. Tibiae of Dapagliflozin treated rats demonstrated decreased cortical tissue mineral density while trabecular tissue mineral density and mean bone mineral density received a rise when compared to the matched controls. ZDF rats also showed defections in femora stiffness which could be relieved by Dapagliflozin administration. The mechanism of Dapagliflozin affecting bone quality is possibly connected to the suppression of serum calcitonin and excretion of calcium via urine rose by hyperglycemia. In conclusion, Dapagliflozin can prevent osteoporosis in ZDF rats by alleviating hypercalciuria.

Sodium-glucose co-transporter-2 inhibitors and the risk of fractures of the upper or lower limbs in patients with type 2 diabetes: A nested case-control study. Diabetes Obes Metab 2019; 21:52-60.

Abstract
AIMS To investigate whether the use of SGLT-2 inhibitors is associated with an increased risk of fractures. MATERIAL AND METHODS We conducted a cohort study with nested case-control analysis based on the InGef database between November 2011 and December 2016 among patients with type 2 diabetes who were initiating treatment with, switching to, or adding a new class of non-insulin antidiabetic drug. Patients with a hospital or ambulatory diagnosis of fractures of the upper or lower limbs were included and were matched to up to 40 randomly sampled control subjects. Conditional logistic regression was used to estimate confounder adjusted odds ratios (ORs) of fractures, comparing current use of metformin plus SGLT-2 inhibitor or metformin plus another antidiabetic drug class to metformin plus DPP-4 inhibitor as reference. RESULTS The cohort comprised 210 042 new users of non-insulin antidiabetic drugs. For the nested case-control analysis, 7522 patients with fractures were matched to 296 845 control subjects. In the crude and confounder adjusted analyses, current use of metformin plus SGLT-2 inhibitor compared to current use of metformin plus DPP-4 inhibitor was not associated with fractures (OR: 1.00; 95% CI: 0.72-1.39 and OR: 0.99; 95% CI: 0.71-1.37, respectively). Similarly, no statistically significant association was found for current use of metformin plus another antidiabetic drug class. No treatment effect modification was observed after stratification by number of documented risk factors for falls and fractures (< 4 vs ≥ 4) and age (< 75 vs ≥ 75 years). CONCLUSION Our study suggests that use of SGLT-2 inhibitors and other antidiabetic drug classes are not associated with an increased risk of fractures of the upper or lower limbs compared to use of DPP-4 inhibitors in patients with type 2 diabetes.

Abstract
Sodium glucose co-transporter-2 inhibitors have attracted the interest of the scientific community following the results from dedicated cardiovascular outcome trials, which demonstrated remarkable reduction in all-cause mortality and other cardiovascular (CV) endpoints with empagliflozin and canagliflozin. These impressive results raised further expectations on real world data from large observational cohort studies. They were designed to address the possible existence of a class effect, and the uncertainty on whether this benefit can be extended from secondary to primary CV prevention of patients with type 2 diabetes. In this review, we collated data from existing observational studies (including the celebrated CVD-REAL cohorts) and critically appraised results and methodological issues with the aim of providing clinical insight, including unsettled aspects, and proposing a research agenda for future investigations.
