Abstract
PURPOSE OF REVIEW Sodium glucose cotransporter 2 (SGLT2) inhibitors are a class of medications initially developed for the treatment of diabetes, although their cardiac and renal protective benefits are far reaching. There has been marked interest in the rheumatology community to adopt these medications into our clinical practice, particularly for chronic kidney disease with persistent proteinuria. RECENT FINDINGS SGLT2 inhibitors have been approved for patients with type 2 diabetes mellitus, heart failure with reduced or preserved ejection fraction, atherosclerotic cardiovascular disease in the setting of type 2 diabetes mellitus, as well as chronic kidney disease with proteinuria. Large studies on SGLT2 inhibitors have largely excluded patients with proteinuric chronic kidney disease due to autoimmune glomerulonephritis due to concerns for confounding from immunosuppression. The Dapagliflozin and Prevention of Adverse Outcomes in CKD Trial (DAPA-CKD) showed that SGLT2 inhibition decreased progression of renal disease in patients with IgA nephropathy. Expanding this to other autoimmune glomerulonephropathies, several small studies have shown improvements in proteinuria in patients with lupus nephritis treated with SGLT2 inhibitors. A study evaluating safety of SGLT2 inhibitors in patients with lupus identified no specific concerns even with concomitant use of immunosuppression. SUMMARY Small studies have shown that SGLT2 inhibitors can been utilized safely and efficaciously in patients with lupus nephritis. Additional research is needed to identify where these medications fit into the rheumatology treatment armamentarium.

Abstract
Highlights A persistent glycosuria alongside hypoglycemia in pediatric type 1 diabetes mellitus needs further evaluation. Morning hypoglycemia is a limiting side effect of sodium glucose transporter 2 (SGLT2) inhibitors in children younger than 5 years old. SLC5A2 mutation functioning as a SGLT2 inhibitor can result in acceptable range of glycated hemoglobin in younger children and lower required doses of insulin.

Abstract
BACKGROUND SGLT2 (sodium-glucose cotransporter 2) inhibitors (SGLT2i) can protect the kidneys and heart, but the underlying mechanism remains poorly understood. METHODS To gain insights on primary effects of SGLT2i that are not confounded by pathophysiologic processes or are secondary to improvement by SGLT2i, we performed an in-depth proteomics, phosphoproteomics, and metabolomics analysis by integrating signatures from multiple metabolic organs and body fluids after 1 week of SGLT2i treatment of nondiabetic as well as diabetic mice with early and uncomplicated hyperglycemia. RESULTS Kidneys of nondiabetic mice reacted most strongly to SGLT2i in terms of proteomic reconfiguration, including evidence for less early proximal tubule glucotoxicity and a broad downregulation of the apical uptake transport machinery (including sodium, glucose, urate, purine bases, and amino acids), supported by mouse and human SGLT2 interactome studies. SGLT2i affected heart and liver signaling, but more reactive organs included the white adipose tissue, showing more lipolysis, and, particularly, the gut microbiome, with a lower relative abundance of bacteria taxa capable of fermenting phenylalanine and tryptophan to cardiovascular uremic toxins, resulting in lower plasma levels of these compounds (including p-cresol sulfate). SGLT2i was detectable in murine stool samples and its addition to human stool microbiota fermentation recapitulated some murine microbiome findings, suggesting direct inhibition of fermentation of aromatic amino acids and tryptophan. In mice lacking SGLT2 and in patients with decompensated heart failure or diabetes, the SGLT2i likewise reduced circulating p-cresol sulfate, and p-cresol impaired contractility and rhythm in human induced pluripotent stem cell-derived engineered heart tissue. CONCLUSIONS SGLT2i reduced microbiome formation of uremic toxins such as p-cresol sulfate and thereby their body exposure and need for renal detoxification, which, combined with direct kidney effects of SGLT2i, including less proximal tubule glucotoxicity and a broad downregulation of apical transporters (including sodium, amino acid, and urate uptake), provides a metabolic foundation for kidney and cardiovascular protection.

J Am Pharm Assoc (2003) 2024; 64:9-26.e6. [PMID: 37844733 DOI: 10.1016/j.japh.2023.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 09/30/2023] [Accepted: 10/09/2023] [Indexed: 10/18/2023]
Abstract
BACKGROUND The U.S. Food and Drug Administration (FDA) revised the labels of sodium-glucose transporter 2 (SGLT2) inhibitors in December 2015 to inform users regarding the risk of diabetic ketoacidosis (DKA). As more drugs of this class are approved and their indications are expanded, this serious adverse effect has been increasingly reported. OBJECTIVE This review evaluated observational studies to inform the prevalence of SGLT2-inhibitor-associated DKA compared with other antihyperglycemic agents. METHODS A systematic review was conducted in PubMed and EMBASE until 19 July 2022 (PROSPERO: CRD42022385425). We included published retrospective cohort active comparator/new user (ACNU) and prevalent new user studies assessing SGLT2-inhibitor-associated DKA prevalence in adult patients with type 2 diabetes mellitus (T2DM) against active comparators. We excluded studies which lacked 1:1 propensity score matching. The JBI Checklist for Cohort Studies guided the risk-of-bias assessments. Meta-analysis was conducted based on the inverse variance method in R software. RESULTS Sixteen studies with a sample of 2,956,100 nonunique patients met the inclusion criteria. Most studies were conducted in North America (n = 9) and adopted the ACNU design (n = 15). Meta-analysis of 14 studies identified 33% higher DKA risk associated with SGLT2 inhibitors (HR = 1.33, 95% CI: 1.14-1.55, P < 0.01). Meta-regression analysis identified the study location (P = 0.02), analysis principle (P < 0.001), exclusion of chronic comorbidities (P = 0.007), and canagliflozin (P = 0.04) as significant moderator variables. CONCLUSIONS Despite limitations related to heterogeneity, generalizability, and misclassification, the results of this study show that SGLT2 inhibitors increase the prevalence of DKA among adult T2DM patients in the real world. The findings supplement evidence from randomized controlled trials (RCTs) and call for continued vigilance.

Abstract
Acute pancreatitis is an acute inflammatory process of the pancreas that requires hospital admission and treatment. There are many causes of pancreatitis, the most common being gallstone and alcohol-induced; other reasons include metabolic, infectious, and medication-induced. A new medication that has come to the market is empagliflozin, which is a sodium-glucose cotransporter-2 inhibitor that is common in managing type 2 diabetes mellitus and congestive heart failure. Although generally considered safe and effective, rare adverse effects have been reported. In this case, we present a 67-year-old female patient who presented with severe acute pancreatitis after two weeks of starting empagliflozin to treat her type 2 diabetes. This case report highlights the importance of considering rare adverse events associated with empagliflozin and the need for close monitoring of patients receiving this medication.

Abstract
NEW FINDINGS What is the central question of this study? Sodium-glucose cotransporter 2 (SGLT2) inhibitors reduce cardiovascular risk in patients with both diabetic and non-diabetic kidney disease: can SGLT2 inhibition improve renal pressure natriuresis (PN), an important mechanism for long-term blood pressure control, which is impaired in type 1 diabetes mellitus (T1DM)? What is the main finding and its importance? The SGLT2 inhibitor dapagliflozin did not enhance the acute in vivo PN response in either healthy or T1DM Sprague-Dawley rats. The data suggest that the mechanism underpinning the clinical benefits of SGLT2 inhibitors on health is unlikely to be due to an enhanced natriuretic response to increased blood pressure. ABSTRACT Type 1 diabetes mellitus (T1DM) leads to serious complications including premature cardiovascular and kidney disease. Hypertension contributes importantly to these adverse outcomes. The renal pressure natriuresis (PN) response, a key regulator of blood pressure (BP), is impaired in rats with T1DM as tubular sodium reabsorption fails to down-regulate with increasing BP. We hypothesised that sodium-glucose cotransporter 2 (SGLT2) inhibitors, which reduce cardiovascular risk in kidney disease, would augment the PN response in T1DM rats. Non-diabetic or T1DM (35-50 mg/kg streptozotocin i.p.) adult male Sprague-Dawley rats were anaesthetised (thiopental 50 mg/kg i.p.) and randomised to receive either dapagliflozin (1 mg/kg i.v.) or vehicle. Baseline sodium excretion was measured and then BP was increased by sequential arterial ligations to induce the PN response. In non-diabetic animals, the natriuretic and diuretic responses to increasing BP were not augmented by dapagliflozin. Dapagliflozin induced glycosuria, but this was not influenced by BP. In T1DM rats the PN response was impaired. Dapagliflozin again increased urinary glucose excretion but did not enhance PN. Inhibition of SGLT2 does not enhance the PN response in rats, either with or without T1DM. SGLT2 makes only a minor contribution to tubular sodium reabsorption and does not contribute to the impaired PN response in T1DM.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a new class of antidiabetic drugs, acting by inhibiting the reabsorption of glucose in the kidneys. They turned out to improve cardiovascular and renal outcomes not only in patients with type 2 diabetes but also in nondiabetic patients. At present, they are more and more widely used in patients without diabetes. Since there were concerns that SGLT2 inhibitors may increase fracture risk in diabetes, the aim of the study was to examine the effect of dapagliflozin and canagliflozin on the musculoskeletal system of nondiabetic, healthy rats. The experiments were carried out on mature female rats, divided into the control rats and rats treated with dapagliflozin (1.4 mg/kg p.o.) or canagliflozin (4.2 mg/kg p.o.) for 4 weeks. Serum bone turnover markers, skeletal muscle strength and mass, bone mass, density, histomorphometric parameters and mechanical properties were determined. Administration of the drugs did not affect the skeletal muscle mass and strength. There was no effect on serum bone turnover markers, and bone mass and composition. However, administration of both drugs resulted in disorders of cancellous bone microarchitecture and worsening of bone mechanical properties. In conclusion, both SGLT2 inhibitors unfavorably affected the skeletal system of healthy rats.

Abstract
SGLT2 inhibitors can protect the kidneys of patients with and without type 2 diabetes mellitus and slow the progression towards end-stage kidney disease. Blocking tubular SGLT2 and spilling glucose into the urine, which triggers a metabolic counter-regulation similar to fasting, provides unique benefits, not only as an anti-hyperglycemic strategy. These include a low hypoglycemia risk and a shift from carbohydrate to lipid utilization and mild ketogenesis, thereby reducing body weight and providing an additional energy source. SGLT2 inhibitors counteract hyperreabsorption in the early proximal tubule, which acutely lowers glomerular pressure and filtration and thereby reduces the physical stress on the filtration barrier, the filtration of tubule-toxic compounds, and the oxygen demand for tubular reabsorption. This improves cortical oxygenation, which, together with lesser tubular gluco-toxicity and improved mitochondrial function and autophagy, can reduce pro-inflammatory, pro-senescence, and pro-fibrotic signaling and preserve tubular function and GFR in the long-term. By shifting transport downstream, SGLT2 inhibitors more equally distribute the transport burden along the nephron and may mimic systemic hypoxia to stimulate erythropoiesis, which improves oxygen delivery to the kidney and other organs. SGLT1 inhibition improves glucose homeostasis by delaying intestinal glucose absorption and by increasing the release of gastrointestinal incretins. Combined SGLT1 and SGLT2 inhibition has additive effects on renal glucose excretion and blood glucose control. SGLT1 in the macula densa senses luminal glucose, which affects glomerular hemodynamics and has implications for blood pressure control. More studies are needed to better define the therapeutic potential of SGLT1 inhibition to protect the kidney, alone or in combination with SGLT2 inhibition.

A Case Series of Ketoacidosis After Coronavirus Disease 2019 Vaccination in Patients With Type 1 Diabetes. Front Endocrinol (Lausanne) 2022; 13:840580. [PMID: 35370952 PMCID: PMC8971718 DOI: 10.3389/fendo.2022.840580] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 01/10/2022] [Indexed: 12/26/2022] Open
Abstract
Introduction We report a case series of severe ketoacidosis after COVID-19 vaccination in a type 1 diabetes patients treated with insulin and an SGLT-2 inhibitor. Case Report We present two cases of type 1 diabetes mellitus. One patient was treated with insulin therapy and an SGLT-2 inhibitor, and the other patient was treated with insulin therapy alone. Both patients became ill after coronavirus disease-2019 vaccination, making it difficult to continue their diet or insulin injections. On admission, they developed severe diabetic ketoacidosis. This is the first report of ketoacidosis after coronavirus disease-2019 vaccination. Conclusion The vaccine should be carefully administered to type 1 diabetes patients receiving intensive insulin therapy and a sodium-glucose transporter due to the high risk ketoacidosis. It is important to instruct patients to drink sufficient fluids and to continue insulin injections when they become sick.

Abstract
Hyperfiltration is an important underlying cause of glomerular dysfunction associated with several systemic and intrinsic glomerular conditions leading to chronic kidney disease (CKD). These include obesity, diabetes, hypertension, focal segmental glomerulosclerosis (FSGS), congenital abnormalities and reduced renal mass (low nephron number). Hyperfiltration-associated biomechanical forces directly impact the cell membrane, generating tensile and fluid flow shear stresses in multiple segments of the nephron. Ongoing research suggests these biomechanical forces as the initial mediators of hyperfiltration-induced deterioration of podocyte structure and function leading to their detachment and irreplaceable loss from the glomerular filtration barrier. Membrane lipid-derived polyunsaturated fatty acids (PUFA) and their metabolites are potent transducers of biomechanical stress from the cell surface to intracellular compartments. Omega-6 and ω-3 long-chain PUFA from membrane phospholipids generate many versatile and autacoid oxylipins that modulate pro-inflammatory as well as anti-inflammatory autocrine and paracrine signaling. We advance the idea that lipid signaling molecules, related enzymes, metabolites and receptors are not just mediators of cellular stress but also potential targets for developing novel interventions. With the growing emphasis on lifestyle changes for wellness, dietary fatty acids are potential adjunct-therapeutics to minimize/treat hyperfiltration-induced progressive glomerular damage and CKD.

Abstract
OBJECTIVE Multiple trials have demonstrated the metabolic effects of sodium/glucose cotransporter 2 (SGLT2) inhibitors in patients regardless of diabetes status, and recent trials have been conducted on the combined sodium/glucose cotransporter 1 and sodium/glucose cotransporter 2 (SGLT1/SGLT2) inhibitors. Therefore, a meta-analysis was conducted to investigate the weight reduction effects and dose-response relationship of SGLT inhibitors and to assess the relative efficacy of SGLT1/SGLT2 inhibitors. METHODS Four electronic databases (PubMed, Embase, Cochrane, and Scopus) were searched on November 21, 2020, for articles published from January 1, 2000, up to November 21, 2020. RESULTS In total, 116 randomized-controlled trials were included, with a combined cohort of 98,497 patients. Overall, patients had a mean weight reduction of -1.79 kg (95% CI: -1.93 to -1.66, p < 0.001) compared with placebo. This effect was observed across diabetes status, duration of follow-up, various comorbidities, and all SGLT drug types. Mean BMI changes were -0.71 kg/m2 (95% CI: -0.94 to -0.47, p < 0.001) compared with placebo. Canagliflozin, empagliflozin, sotagliflozin, and licogliflozin showed a dose-response relationship for mean weight change. Compared with SGLT2 inhibitors, SGLT1/SGLT2 inhibitors had a significantly larger reduction in weight. CONCLUSIONS SGLT inhibitors demonstrated weight reduction benefits in this meta-analysis. Further studies are needed to clarify their role in weight management.

Abstract
The proximal tubule of the kidney is programmed to reabsorb all filtered glucose and fructose. Glucose is taken up by apical sodium-glucose cotransporters SGLT2 and SGLT1 whereas SGLT5 and potentially SGLT4 and GLUT5 have been implicated in apical fructose uptake. The glucose taken up by the proximal tubule is typically not metabolized but leaves via the basolateral facilitative glucose transporter GLUT2 and is returned to the systemic circulation or used as an energy source by distal tubular segments after basolateral uptake via GLUT1. The proximal tubule generates new glucose in metabolic acidosis and the postabsorptive phase, and fructose serves as an important substrate. In fact, under physiological conditions and intake, fructose taken up by proximal tubules is primarily utilized for gluconeogenesis. In the diabetic kidney, glucose is retained and gluconeogenesis enhanced, the latter in part driven by fructose. This is maladaptive as it sustains hyperglycemia. Moreover, renal glucose retention is coupled to sodium retention through SGLT2 and SGLT1, which induces secondary deleterious effects. SGLT2 inhibitors are new anti-hyperglycemic drugs that can protect the kidneys and heart from failing independent of kidney function and diabetes. Dietary excess of fructose also induces tubular injury. This can be magnified by kidney formation of fructose under pathological conditions. Fructose metabolism is linked to urate formation, which partially accounts for fructose-induced tubular injury, inflammation, and hemodynamic alterations. Fructose metabolism favors glycolysis over mitochondrial respiration as urate suppresses aconitase in the tricarboxylic acid cycle, and has been linked to potentially detrimental aerobic glycolysis (Warburg effect). © 2022 American Physiological Society.

Abstract
BACKGROUND AND OBJECTIVE In recent trials, sodium-glucose cotransporter 2 (SGLT2) inhibitors proved effective as treatment for heart failure. However, the relative efficacy of sacubitril/valsartan against SGLT2 inhibitor in patients with heart failure remains unknown. Hence, we performed a network meta-analysis to compare the effects of sacubitril/valsartan against SGLT2 inhibitors on cardiovascular outcomes in patients with heart failure. METHODS Four electronic databases (PubMed, Embase, Cochrane, SCOPUS) were searched for randomised-controlled trials (RCTs) published from 1st January 2000 to 25th September 2021. Two additional systematic reviews were conducted for RCTs of enalapril and valsartan to establish a common comparator arm. Frequentist network meta-analysis models were utilised to summarise the studies. RESULTS Twenty-five RCTs were included, comprising a combined cohort of 47,275 patients. Network meta-analysis demonstrated that compared to SGLT2 inhibitors, sacubitril/valsartan achieved a larger hazard rate reduction in the composite of heart failure hospitalisation and cardiovascular death (hazard ratio [HR]: 0.86; 95% CI 0.75-0.98), cardiovascular death (HR: 0.78; 95% CI 0.65-0.94), and a larger mean change in systolic blood pressure at 8 or more months (weighted mean difference [WMD]: - 7.08 mmHg; 95% CI - 8.28 to - 5.89). There were no significant differences in treatment effects across heart failure hospitalisation, all-cause mortality, diastolic blood pressure at 12 weeks, and systolic blood pressure at 2-4 months. In patients with heart failure with reduced ejection fraction, sacubitril/valsartan achieved a 20% hazard rate reduction for cardiovascular death compared to SGLT2 inhibitors. CONCLUSIONS In patients with heart failure, sacubitril/valsartan was demonstrated to be superior to SGLT2 inhibitors in the treatment effect for the composite of heart failure hospitalisation and cardiovascular death, cardiovascular death, and long-term blood pressure.

Abstract
OBJECTIVES Recent clinical trials have shown the potential of sodium glucose cotransporter (SGLT) 2 inhibitors to reduce the risk of atrial fibrillation but not stroke. We conducted a systematic review and meta-analysis to clarify if SGLT2 or combined SGLT1/2 inhibitors affect the risk of atrial fibrillation and stroke in patients regardless of diabetic status. MATERIALS AND METHODS Four electronic databases were searched on 21st November 2020 for studies evaluating outcomes of stroke and atrial fibrillation with SGLT2 or combined SGLT1/2 inhibitors in both diabetic and non-diabetic patients. Both random and fixed effect, pair-wise meta-analysis models were used to summarize the results of the studies. RESULTS A total of 13 placebo-controlled, randomized-controlled trials were included. Eight trials comprising 35,702 patients were included in the analysis of atrial fibrillation outcomes and eight trials comprising 47,910 patients were included in the analysis of stroke outcomes. Patients on SGLT inhibitors, particularly SGLT2 inhibitors, had lower odds of atrial fibrillation (Peto odds ratio [95% confidence interval] = 0.76 [0.63-0.92]) compared to placebo. This effect remained significant with a follow-up duration longer than 1 year, in studies utilizing dapagliflozin, patients with type 2 diabetes mellitus, and patients with cardiovascular disease. No difference was observed in the odds of atrial fibrillation in patients with baseline heart failure. No effect was seen on the risk of stroke in patients taking SGLT inhibitors. CONCLUSIONS SGLT2 inhibitors significantly reduced the odds of atrial fibrillation in diabetic patients. However, SGLT inhibitors did not significantly affect the risk of stroke.

Abstract
PURPOSE OF REVIEW Type 1 diabetes mellitus (T1DM) is associated with increased mortality, with premature cardiovascular disease (CVD) a major factor. To date, research has identified multiple risk factors for this excess CVD liability. However, gaps remain in our understanding of the underlying mechanisms. RECENT FINDINGS T1DM is generally diagnosed at a young age. Since cardiovascular complications often only manifest at a later stage of life, there is generally less focus in earlier years on reducing CVD risk for affected individuals. This is an area that requires improvement as risk factors might be managed from earlier age to reduce later development of CVD. In this review, we discuss the evidence for cardiovascular risk factors, risk prediction models, candidate surrogate measurements and CVD risk management.

Abstract
BACKGROUND Currently, there are a number of sodium glucose co-transport-2 (SGLT2) inhibitors that are under development or in clinical trials. Prior meta-analyses had established the safety and efficacy of SGLT2 inhibitors in type 1 diabetes mellitus (T1DM), but with low level of evidences and inconsistent conclusions. However, recently many new randomized clinical trials (RCTs) have been published, we hence try to design a study protocol to assess the effect of SGLT2 inhibitors on cardiovascular events via a comprehensive meta-analysis of data from much more RCTs, including sensitivity and subgroup analyses. METHODS We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines to conduct this meta-analysis. Two investigators will perform a systematic search of scientific literature in the databases (from conception through June 12, 2021), including PubMed, Embase, and Cochrane Central Register of Controlled Trials. This meta-analysis will be conducted using RevMan statistical software. The risk of bias for each included study will be assessed using the Cochrane Risk of Bias Assessment Tool. RESULTS Our protocol is conceived to test the hypothesis that SGLT2 inhibitors could lead to better outcomes in patients presenting with T1DM. REGISTRATION NUMBER 10.17605/OSF.IO/ZD8WX.

Abstract
Recent years have seen a paradigm shift in the management of patients with diabetes mellitus. Rather than good glycaemic control being the sole primary aim, the therapeutic focus has broadened to consider potential additional cardiovascular and renal benefits. Sodium-glucose co-transporter 2 inhibitors, such as empagliflozin, canagliflozin and dapagliflozin, have gained increasing prominence, with evidence suggesting significant improvement in outcomes in patients with established cardiovascular and renal disease. Here, we discuss the benefits and relative risks of these novel agents and highlight important clinical issues of relevance to general physicians.

Abstract
MONITORING With the increasing prevalence of continuous glucose monitoring (CGM) systems, time in range (TIR) is gaining importance as a parameter for optimization of glycemic control in patients with type 1 diabetes mellitus. Recent studies showed improved prevention of cardiovascular events and pregnancy complications in patients with optimized TIR. In addition to TIR, it is recommended to consider Time below Range (TBR) as well to include an assessment of hypoglycemia. HYPOGLYCEMIA Hypoglycemia remains a clinically relevant complication of therapy for type 1 diabetes mellitus. With the approval of nasal glucagon, there is now an alternative to traditional injections as an easy-to-use emergency therapy. With the development of the glucagon analogue Dasiglucagon, which is stable in the liquid state, a classic emergency pen with a ready-to-use solution will also potentially be available in the near future. INSULIN THERAPY The new fast-acting insulin aspart (FIASP) offers new opportunities for blood glucose optimization in type 1 diabetes patients. Furthermore, the first hybrid closed-loop system for the treatment of type 1 diabetes mellitus was approved in Germany in 2019. This system automatically adjusts the basal rate based to blood glucose levels measured by CGM. When used adequately, a hybrid closed-loop system allows for improved glycemic control, particularly of nocturnal blood glucose. COMPLEMENTARY THERAPIES Since 2019, the SGLT-2 inhibitor dapagliflozin and the combined SGLT-1/2 inhibitor sotagliflozin have been approved for the therapy of inadequately controlled type 1 diabetics with a BMI above 27 kg/m² and no elevated risk of diabetic ketoacidosis. The most relevant side effect is atypical normoglycemic ketoacidosis, which is why initial risk assessment and adequate training of the patient to perform and interpret ketone body and pH measurements during therapy are of central importance.

Abstract
PURPOSE Diabetic ketoacidosis (DKA) is a rare and life-threatening complication in patients with diabetes. Sodium-glucose co-transporter-2 inhibitors (SGLT2i) have rarely been associated with ketoacidosis. The aim of this retrospective study was to investigate DKA episodes occurring after SGLT2i treatment and to compare them to DKA episodes due to other causes. METHODS The medical records of the years 2018-2020 related to clinical and biochemical characteristics and to treatment of six patients with DKA due to SGLT2i were reviewed. They were compared to those of 12 patients with DKA due to other causes. RESULTS On admission, the most common symptom was abdominal pain. Glucose levels (median, min-max) were lower in patients with SGLT2i-induced DKA compared to those with DKA due to other causes (229 (150-481) vs. 458.5 (332-695) mg/dl, p = 0.007), whereas no statistical difference was observed in HbA1c and in the severity of DKA (pH, HCO3, CO2, and anion gap). The duration of insulin infusion (41 (33-124) vs. 21.50 (11-32) h, p < 0.001) and the time required until DKA resolution (39 (31-120) vs. 19 (9-28) h, p < 0.001) were higher in patients with SGLT2i-induced DKA than those with DKA due to other causes. In addition, there were increased fluid requirements (14 (8-22.75) vs. 5.5 (2-24) L, p = 0.013) and longer hospitalization time (11 (6-22) vs. 5.5 (2-14) days, p = 0.024) in patients with SGLT2i-induced DKA. No statistically significant differences were observed in total intravenous insulin and potassium administration until DKA resolution. CONCLUSIONS Patients with SGLT2i-induced DKA had lower serum glucose levels on admission and required increased fluid administration and longer time to recover from acidosis compared to patients with DKA from other causes.

Abstract
PURPOSE Empagliflozin, dapagliflozin, canagliflozin, and ertugliflozin have been shown in randomized controlled trials to improve cardiovascular, metabolic, and renal outcomes in heart failure patients. To date, there has not been any meta-analysis examining the differences in clinical outcomes across different SGLT2 inhibitors in heart failure patients. METHODS Four electronic databases (PubMed, Embase, Cochrane, SCOPUS) were searched on 13 September 2020 for articles published from 1 January 2000 to 13 September 2020 examining the effect of SGLT2 inhibitors on cardiovascular, renal, and metabolic outcomes in heart failure patients. Frequentist network meta-analysis was performed on extracted data. RESULTS Ten randomized controlled trials were included with a combined cohort of 15,373 patients. In heart failure patients, frequentist network meta-analysis demonstrated no demonstrable difference in treatment effect across the SGLT2 inhibitors for heart failure hospitalization, cardiovascular deaths, composite of cardiovascular deaths and heart failure hospitalizations, all-cause mortality, and a composite of cardiovascular deaths and non-fatal myocardial infarction and non-fatal stroke. There was no demonstrable difference in treatment effect for worsening renal function or the weighted mean difference for weight, hemoglobin A1c, and systolic blood pressure. CONCLUSIONS There were no demonstrable treatment differences across SGLT2 inhibitors across cardiovascular, renal, and metabolic outcomes, although this needs to be interpreted considering the wide confidence intervals, limited number of included studies, and heterogeneity present. Future research of different SGLT2 inhibitors in head-to-head studies is warranted to determine if there is a drug class effect.

Abstract
Beta-cell destruction in type 1 diabetes (T1D) results from the combined effect of inflammation and recurrent autoimmunity. In response to inflammatory signals, beta-cells engage adaptive mechanisms where the endoplasmic reticulum (ER) and mitochondria act in concert to restore cellular homeostasis. In the recent years it has become clear that this adaptive phase may trigger the development of autoimmunity by the generation of autoantigens recognized by autoreactive CD8 T cells. The participation of the ER stress and the unfolded protein response to the increased visibility of beta-cells to the immune system has been largely described. However, the role of the other cellular organelles, and in particular the mitochondria that are central mediator for beta-cell survival and function, remains poorly investigated. In this review we will dissect the crosstalk between the ER and mitochondria in the context of T1D, highlighting the key role played by this interaction in beta-cell dysfunctions and immune activation, especially through regulation of calcium homeostasis, oxidative stress and generation of mitochondrial-derived factors.

Abstract
The prevalence of type 1 diabetes (T1D) is increasing worldwide. T1D reduces life expectancy due to complications including cardiovascular disease. Sodium-glucose co-transporter (SGLT) inhibitors are a new class of drugs developed to treat type 2 diabetes (T2D), and now they can be used as an adjunct to insulin in T1D. In clinical trials, they have been shown to improve glycaemic control and decrease body weight without the risk of increased hypoglycaemia and with a reduction in insulin dose. Four SGLT2 inhibitors have been approved in Europe for the treatment of T2D, while only dapagliflozin and sotagliflozin, a dual SGLT1 and SGLT2 inhibitor approved in 2019, have been approved for the treatment of T1D. Both can be used as an adjunct therapy in combination with insulin in adults with a body mass index (BMI) of ≥27 kg/m2, inadequately controlled with insulin. In Europe, dapagliflozin is the only currently available SGLT2 inhibitor indcated as adjunct therapy for patients with T1D. The subgroup of patients with a BMI of ≥27 kg/m2 from the DEPICT-1 and -2 trials (Dapagliflozin Evaluation in Patients with Inadequately Controlled Type 1 diabetes) showed similar reduction in hyperglycaemia and body weight but no significant increased risk of diabetic ketoacidosis (DKA) than the overall trial population. The risk of DKA has been shown to increase in patients with T1D treated with adjunct therapy with SGLT2 inhibitors, and studies on sotagliflozin and empagliflozin have suggested a dose response. Thus, it is important to educate patients and doctors how to recognize symptoms of upcoming DKA and mitigate it. An independent DKA education programme has recently been developed to instruct patients with T1D being treated with SGLT inhibitor therapies with and without insulin pumps to prevent, identify and treat DKA. Despite these considerations, clinical trials support the use of SGLT2 inhibitors in the management of T1D. The benefits and potential risks of dapagliflozin as an adjunct therapy to insulin in adults with T1D should be considered in each individual case. Here we discuss the efficacy and safety of dapagliflozin as adjunct therapy in patients with T1D.

Abstract
Background Recent studies have increasingly shown that sodium‐glucose cotransporter 2 (SGLT2) inhibitors may have beneficial cardiovascular and metabolic effects in patients without diabetes mellitus. Hence, we conducted a systematic review and meta‐analysis to determine the effect of SGLT2 inhibitors on cardiovascular and metabolic outcomes in patients without diabetes mellitus. Methods and Results Four electronic databases (PubMed, Embase, Cochrane, and SCOPUS) were searched on August 30, 2020 for articles published from January 1, 2000 to August 30, 2020, for studies that examined the effect of SGLT2 inhibitors on cardiovascular and metabolic outcomes in patients without diabetes mellitus. A random‐effects pairwise meta‐analysis model was used to summarize the studies. A total of 8 randomized‐controlled trials were included with a combined cohort of 5233 patients. In patients without diabetes mellitus, those with heart failure treated with SGLT2 inhibitors had a 20% relative risk reduction in cardiovascular deaths and heart failure hospitalizations, compared with those who were not treated (risk ratio, 0.78; P<0.001). We additionally found that treatment with SGLT2 inhibitors improved multiple metabolic indices. Patients on SGLT2 inhibitors had a reduction in body weight of −1.21 kg (P<0.001), body mass index of −0.47 kg/m2 (P<0.001), systolic blood pressure of −1.90 mm Hg (P=0.04), and fasting plasma glucose of −0.38 mmol/L (P=0.05), compared with those without. There were no between‐group differences in NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) levels, waist circumference, diastolic blood pressure, glycated hemoglobin, low‐density lipoprotein cholesterol levels, and estimated glomerular filtration rates. Across our combined cohort of 5233 patients, hypoglycemia was reported in 22 patients. Conclusions SGLT2 inhibitors improve cardiovascular outcomes in patients without diabetes mellitus with heart failure. In patients without diabetes mellitus, SGLT2 inhibitors showed positive metabolic outcomes in weight and blood pressure control.

Abstract
AIM To evaluate the efficacy and safety of adjunct dapagliflozin therapy in patients with type 1 diabetes (T1D). MATERIALS AND METHODS DEPICT-1 and -2 were randomized, double-blind, parallel-group, 24-week studies, with 28-week extension periods. Adults with T1D and HbA1c 7.5%-10.5% were randomized (1:1:1) to receive dapagliflozin 5 mg, 10 mg or placebo. The short- and long-term efficacy and safety of dapagliflozin were examined in an exploratory pooled analysis of both studies. RESULTS Efficacy analyses included 530, 529 and 532 and safety analysis included 548, 566 and 532 patients in the dapagliflozin 5 mg, 10 mg and placebo groups, respectively. Baseline characteristics were similar between treatment groups. At week 24, reductions were seen with dapagliflozin 5 and 10 mg compared with placebo in HbA1c (-0.40%, -0.43% vs. 0.00%) and body weight (-2.45, -2.91 vs. 0.11 kg). HbA1c and body weight reductions versus placebo were also seen after 52 weeks of treatment. There was no imbalance in occurrence of severe hypoglycaemic events between groups. The proportion of patients experiencing definite diabetic ketoacidosis (DKA) was higher with dapagliflozin 5 mg (4.0%) and 10 mg (3.5%) compared with placebo (1.1%) over 52 weeks; most events were of mild or moderate severity, and all resolved with treatment. CONCLUSIONS Over 52 weeks, dapagliflozin provided glycaemic and weight benefits, with no increased frequency of severe hypoglycaemia compared with placebo. More DKA events were reported with dapagliflozin than placebo, highlighting the importance of appropriate patient selection, education and risk-mitigation strategies.

Abstract
Acute pancreatitis is an acute inflammatory process of the pancreas that is associated with multiple etiologies. The two most common causes are gallstones and acute alcohol intoxication. However, medications are often overlooked when determining the cause. Empagliflozin is a type of sodium-glucose transport protein 2 (SGLT-2) inhibitor used for the treatment of type 2 diabetes mellitus. Given that this medication is new, the adverse effects have not been fully reported in the literature. Currently, the most commonly reported side effects are genitourinary infections such as cystitis or yeast infection although acute pancreatitis as a result of empagliflozin is very rare. Here, we discuss a case of a 64-year-old female who presented with severe pancreatitis after recently initiating the use of empagliflozin. Based on the timing of her presentation and her hospital workup to rule out many of the common etiologies, it was concluded that empagliflozin was the likely cause of her acute pancreatitis. With SGLT-2 inhibitors such as empagliflozin, becoming popular as first-line in the management of diabetes, this case may hope to raise awareness of the possible adverse effects related to it. Additionally, this case also emphasizes the importance of identifying iatrogenic related pancreatitis.

Abstract
Background: Diabetes mellitus (DM) is a chronic disease that affects public health. The prediction of blood glucose concentration (BGC) is essential to improve the therapy of type 1 DM (T1DM). Methods: Having considered the risk of hyper- and hypo-glycemia, we provide a new hybrid modeling approach for BGC prediction based on a dynamic wavelet neural network (WNN) model, including a heuristic input selection. The proposed models include a hybrid dynamic WNN (HDWNN) and a hybrid dynamic fuzzy WNN (HDFWNN). These wavelet-based networks are designed based on dominant wavelets selected by the genetic algorithm-orthogonal least square method. Furthermore, the HDFWNN model structure is improved using fuzzy rule induction, an important innovation in the fuzzy wavelet modeling. The proposed networks are tested on real data from 12 T1DM patients and also simulated data from 33 virtual patients with an UVa/ Padova simulator, an approved simulator by the US Food and Drug Administration. Results: A comparison study is performed in terms of new glucose-based assessment metrics, such as gFIT, glucose-weighted form of ESODn (gESODn), and glucose-weighted R2 (gR2). For real patients’ data, the values of the mentioned indices are accomplished as gFIT = 0.97 ± 0.01, gESODn = 1.18 ± 0.38, and gR2 = 0.88 ± 0.07. HDFWNN, HDWNN and jump NN method showed the prediction error (root mean square error [RMSE]) of 11.23 ± 2.77 mg/dl, 10.79 ± 3.86 mg/dl and 16.45 ± 4.33 mg/dl, respectively. Conclusion: Furthermore, the generalized estimating equation and post hoc tests show that proposed models perform better compared with other proposed methods.

Scheen AJ. Sodium-glucose cotransporter type 2 inhibitors for the treatment of type 2 diabetes mellitus. Nat Rev Endocrinol 2020; 16:556-577.

Abstract
The management of type 2 diabetes mellitus (T2DM) is becoming increasingly complex. Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are the newest antidiabetic agents for T2DM. By targeting the kidney, they have a unique mechanism of action, which results in enhanced glucosuria, osmotic diuresis and natriuresis, thereby improving glucose control with a limited risk of hypoglycaemia and exerting additional positive effects such as weight loss and the lowering of blood pressure. Several outcome studies with canagliflozin, dapagliflozin or empagliflozin reported a statistically significant reduction in major cardiovascular events, hospitalization for heart failure and progression to advanced renal disease in patients with T2DM who have established atherosclerotic cardiovascular disease, several cardiovascular risk factors, albuminuric mild to moderate chronic kidney disease or heart failure. Current guidelines proposed a new paradigm in the management of T2DM, with a preferential place for SGLT2is, after metformin, in patients with atherosclerotic cardiovascular disease, heart failure and progressive kidney disease. Ongoing trials might extend the therapeutic potential of SGLT2is in patients with, but also without, T2DM. This Review provides an update of the current knowledge on SGLT2is, moving from their use as glucose-lowering medications to their new positioning as cardiovascular and renal protective agents.

Abstract
The mainstay of treatment for type 1 diabetes is insulin. The use of insulin for tight glycemic control is the key to preventing micro- and macrovascular complications, but it can also lead to hypoglycemic episodes. Therefore, there is a need for the introduction of a drug that can maintain glucose levels within a safe range without increasing the risk of hypoglycemia. For this reason, SGLT2 (sodium-glucose co-transporter-2) inhibitors has been a hot topic in the last couple of years. They have been proved very efficient in treating type 2 diabetes. Many trials on the safety and efficacy of SGLT2 inhibitors have been done on type 1 diabetics. Some other studies have also been done that prove their benefits in increasing arterial efficacy and reducing GFR (glomerular filtration rate). This review article discusses the benefits and risks. The literature search was performed using PubMed, and after applying the inclusion and exclusion criteria, 16 published papers were found. All relevant articles on the topic have been included. Our review has shown that the benefits of SGLT2 inhibitors outweigh their risks. Their benefits include good glycemic control, HBA1c (glycated haemoglobin) reduction, weight loss, and blood pressure improvement. Furthermore, improvement in GFR and arterial efficacy is also significant. Side effects such as UTI (urinary tract infection) and genital infection have been observed, but their incidence is low. However, DKA (diabetic ketoacidosis) and hypoglycemia are severe side effects that should be highlighted. Hypoglycemia can be prevented by strictly monitoring blood sugar levels. The patient must be educated and counseled about DKA and its symptoms. This will ensure the safety of the patient as euglycemic DKA can prove fatal if not diagnosed earlier. So, SGLT2 inhibitors can be used as an effective drug to control blood sugar levels in type 1 diabetes, especially in patients with a BMI higher than 30. It will not only achieve the treatment goals but can also decrease the morbidity and mortality of the patients. However, more studies need to be done to fully understand DKA caused by SGLT2 inhibitors.

Abstract
PURPOSE OF REVIEW Emerging data have suggested that β-cell dysfunction may exacerbate the development and progression of type 1 diabetes (T1D). In this review, we highlight clinical and preclinical studies suggesting a role for β-cell dysfunction during the evolution of T1D and suggest agents that may promote β-cell health in T1D. RECENT FINDINGS Metabolic abnormalities exist years before development of hyperglycemia and exhibit a reproducible pattern reflecting progressive deterioration of β-cell function and increases in β-cell stress and death. Preclinical studies indicate that T1D may be prevented by modification of pathways impacting intrinsic β-cell stress and antigen presentation. Recent findings suggest that differences in metabolic phenotypes and β-cell stress may reflect differing endotypes of T1D. Multiple pathways representing potential drug targets have been identified, but most remain to be tested in human populations with preclinical disease. SUMMARY This cumulative body of work shows clear evidence that β-cell stress, dysfunction, and death are harbingers of impending T1D and likely contribute to progression of disease and insulin deficiency. Treatment with agents targeting β-cell health could augment interventions with immunomodulatory therapies but will need to be tested in intervention studies with endpoints carefully designed to capture changes in β-cell function and health.

Diabetes Care 2020; 43:1741-1749. [PMID: 32532756 PMCID: PMC7372053 DOI: 10.2337/dc19-2249] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 04/23/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To develop a patient-level simulation model for predicting lifetime health outcomes of patients with type 1 diabetes and as a tool for economic evaluation of type 1 diabetes treatment based on data from a large, longitudinal cohort. RESEARCH DESIGN AND METHODS Data for model development were obtained from the Swedish National Diabetes Register. We derived parametric proportional hazards models predicting the absolute risk of diabetes complications and death based on a wide range of clinical variables and history of complications. We used linear regression models to predict risk factor progression. Internal validation was performed, estimates of life expectancies for different age-sex strata were computed, and the impact of key risk factors on life expectancy was assessed. RESULTS The study population consisted of 27,841 patients with type 1 diabetes with a mean duration of follow-up of 7 years. Internal validation showed good agreement between the predicted and observed cumulative incidence of death and 10 complications. Simulated life expectancy was ∼13 years lower than that of the sex- and age-matched general population, and patients with type 1 diabetes could expect to live with one or more complications for ∼40% of their remaining life. Sensitivity analysis showed the importance of preventing renal dysfunction, hypoglycemia, and hyperglycemia as well as lowering HbA1c in reducing the risk of complications and death. CONCLUSIONS Our model was able to simulate risk factor progression and event histories that closely match the observed outcomes and to project events occurring over patients' lifetimes. The model can serve as a tool to estimate the impact of changing clinical risk factors on health outcomes to inform economic evaluations of interventions in type 1 diabetes.

Fournier Gangrene Associated with Sodium-Glucose Cotransporter-2 Inhibitors: A Pharmacovigilance Study with Data from the U.S. FDA Adverse Event Reporting System. J Diabetes Res 2020; 2020:3695101. [PMID: 32695827 PMCID: PMC7368210 DOI: 10.1155/2020/3695101] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 06/01/2020] [Accepted: 06/16/2020] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The U.S. Food and Drug Administration (FDA) released a safety warning of Fournier gangrene (FG), a rare but serious adverse effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors in August 2018. However, existing studies have focused mainly on individual FG case reports. Although several previous studies conducted reviews of cases, objective scientific analysis was not applied, and the prognosis data were inadequate. OBJECTIVE This study is aimed at presenting data supplementary to existing studies by analysing postmarketing adverse event reports in the FDA Adverse Events Reporting System (FAERS) database. Multiple statistical analysis methods were applied to evaluate the potential association between SGLT2 inhibitors and FG, thus providing reliable and professionalized medication usage recommendations for SGLT2 inhibitors in clinical practice. METHODS Disproportionality analysis and Bayesian analysis were applied for data mining among the suspected adverse event reports of FG associated with SGLT2 inhibitors recorded in the FAERS database during the period from January 2004 to September 2019. RESULTS There were 542 FG cases identified in the FAERS database in patients receiving SGLT2 inhibitors. Among all SGLT2 inhibitor therapies, empagliflozin was associated with the highest number of FG reports (232 in total), while empagliflozin plus metformin had the strongest association with FG occurrence with the reporting odds ratio (ROR 54.79, 95% two-sided CI 31.56 to 95.12) and proportional reporting ratio (PRR 53.36, χ 2 666.70). There were 391 patients who underwent initial or prolonged hospitalization (72.14%), and 26 patients died (4.81%). Three new FG cases caused by ertugliflozin were found in 2019. CONCLUSION The analysis of SGLT2 inhibitor-associated FG reports in the FAERS database identified signals between the drug and adverse events of interest. It also provides comprehensive information on the characteristics of FG onset and prognosis. Clinicians should pay more attention to this rare but severe adverse event when prescribing SGLT2 inhibitors in clinical practice.

Abstract
BACKGROUND Type 1 diabetes (T1D) is associated with major chronic microvascular complications which contribute significantly to diabetes associated morbidity. The protein primarily responsible for glucose reabsorption in the kidney is sodium glucose co-transporter 2 (SGLT2). Presently, SGLT2 inhibitors are widely used in diabetic patients to improve blood glucose levels and prevent cardiovascular and renal complications. Given the broad therapeutic application of SGLT2 inhibitors, we hypothesised that SGLT2 inhibition may exert its protective effects via alterations of the gut microbiome and tested this in a type 1 diabetic mouse model of diabetic retinopathy.
AIM To determine whether the treatment with two independent SGLT2 inhibitors affects gut health in a type 1 diabetic mouse model.
METHODS The SGLT2 inhibitors empagliflozin or dapagliflozin (25 mg/kg/d) or vehicle dimethylsulfoxide (DMSO) were administered to C57BL/6J, Akita, Kimba and Akimba mice at 10 wk of age for 8 wk via their drinking water. Serum samples were collected and the concentration of succinate and the short chain fatty acid (SCFA) butyric acid was measured using gas chromatography-mass spectrometry. Enzyme-linked immunosorbent assay (ELISA) was performed to determine the concentration of insulin and leptin. Furthermore, the norepinephrine content in kidney tissue was determined using ELISA. Pancreatic tissue was collected and stained with haematoxylin and eosin and analysed using brightfield microscopy.
RESULTS Due to the presence of the Akita allele, both Akita and Akimba mice showed a reduction in insulin production compared to C57BL/6J and Kimba mice. Furthermore, Akita mice also showed the presence of apoptotic bodies within the pancreatic islets. The acinar cells of Akita and Akimba mice showed swelling which is indicative of acute injury or pancreatitis. After 8 wk of SGLT2 inhibition with dapagliflozin, the intermediate metabolite of gut metabolism known as succinate was significantly reduced in Akimba mice when compared to DMSO treated mice. In addition, empagliflozin resulted in suppression of succinate levels in Akimba mice. The beneficial SCFA known as butyric acid was significantly increased in Akita mice after treatment with dapagliflozin when compared to vehicle treated mice. The norepinephrine content in the kidney was significantly reduced with both dapagliflozin and empagliflozin therapy in Akita mice and was significantly reduced in Akimba mice treated with empagliflozin. In non-diabetic C57BL/6J and Kimba mice, serum leptin levels were significantly reduced after dapagliflozin therapy.
CONCLUSION The inhibition of SGLT2 reduces the intermediate metabolite succinate, increases SCFA butyric acid levels and reduces norepinephrine content in mouse models of T1D. Collectively, these improvements may represent an important mechanism underlying the potential benefits of SGLT2 inhibition in T1D and its complications.

Abstract
OBJECTIVES The proposed review aims to compare the efficacy and safety profile of empagliflozin 25 mg with its lower dosages and placebo, respectively, in insulin-treated type 1 diabetes mellitus (T1DM) patients. METHODS Double-blinded randomized controlled trials comparing the above outcomes will be searched primarily in three electronic databases (PubMed, Embase, and Scopus) and eligible trials will be included in the proposed review. Then, from the trials recruited in the review, data of the study design, participants, interventions compared, and outcomes of interest will be extracted. Subsequently, the trials' risk of bias will be assessed using the Cochrane Collaboration's tool. The meta-analysis will be conducted with a fixed-effect or a random-effect model to estimate the mean differences (weighted or standardized) and risk ratios for the efficacy and safety-related comparable outcome data, respectively. Statistical heterogeneity will be assessed by the p-value of chi-squared statistics and I2 statistics and explained by subgroup analysis and meta-regression. Publication bias will be assessed by funnel plots and Egger's test. The sensitivity analysis will repeat the meta-analysis for respective outcomes using assumptions alternative to that used in the preliminary meta-analysis and by dropping each study at a time. RESULTS A narrative reporting will ensue if a meta-analytic comparison is not possible. CONCLUSIONS Based on the contemporary literature, the proposed review will synthesize the evidence on how the efficacy and safety profile of high dose empagliflozin varies with its lower doses and placebo, respectively, in insulin-treated T1DM patients.

Abstract
BACKGROUND Although, number of diabetic patients received insulin pump (IP) therapy is increasing; there are limited data regarding factors associated with IP withdrawal. METHODS We conducted a cross-sectional study using data from an Israeli health maintenance organization. All patients, 21 or older, with type 1 (T1DM) or type 2 (T2DM) diabetes, who received IP therapy for a 7-year period were identified. Patients who did not purchase IP maintenance supplies for at least six consecutive months were defined as withdrawn (N = 355). Patients who purchased supplies were defined as adherent (N = 352). RESULTS In both T1DM and T2DM patients, withdrawal from IP therapy was positively associated with duration of diabetes longer than 5 years (odds ratio [OR] = 13.26 [CI, 7.16-23.34; P < .001] and OR = 10.92 [CI, 5.64-21.14; P < .001], respectively), nonadherence to dietician follow-up (OR = 5.78 [CI, 3.65-9.14; P < .001] and OR = 3.41 [CI, 1.99-5.85; P < .001], respectively), and poor glycaemic control prior to IP treatment (OR = 4.04 [CI, 2.18-7.48; P < .001] and OR = 4.59 [CI, 2.71-7.81; P < .001], respectively]. Co-morbid neuro-psychiatric disorders were also risk factors for IP withdrawal: diagnosis of depression (OR = 2.22 [CI, 1.16-4.27; P = .017] and Attention Deficit Hyperactivity Disorder (ADHD) OR = 2.45 [CI, 1.003-5.087; P = .043]) among T1DM patients; and diagnosis of depression (OR = 1.85 [CI, 1.05-5.27; P = .046] and dementia OR = 4.03 [CI, 1.03-19.77; P = .048]) among T2DM patients. CONCLUSION In our large real-world population-based study, we found that smoking, obesity, poor glycaemic control, and co-morbid neuro-psychiatric disorders were associated with a high rate of withdrawal from IP therapy. Health care providers ought to familiarize themselves with patient characteristics predictive of nonadherence and should intensify patient follow-up when incorporating this new, costly, and challenging technology.

Abstract
Type 1 diabetes is an autoimmune disease caused by the immune-mediated destruction of pancreatic β cells that results in lifelong absolute insulin deficiency. For nearly a century, insulin replacement has been the only therapy for most people living with this disease. Recent advances in technology and our understanding of β cell development, glucose metabolism, and the underlying immune pathogenesis of the disease have led to innovative therapeutic and preventative approaches. A paradigm shift in immunotherapy development toward the targeting of islet-specific immune pathways involved in tolerance has driven the development of therapies that may allow for the prevention or reversal of this disease while avoiding toxicities associated with historical approaches that were broadly immunosuppressive. In this review, we discuss successes, failures, and emerging pharmacological therapies for type 1 diabetes that are changing how we approach this disease, from improving glycemic control to developing the "holy grail" of disease prevention.

Abstract
OBJECTIVES While empagliflozin (25 mg) is used to treat type-2 diabetes mellitus patients with optimum renal functioning, its efficacy and safety in type-1 diabetes mellitus (T1DM) is not yet established. Therefore, this study aimed to compare insulin-treated T1DM patients' (with adequate renal functioning) glycemic and blood pressure control between the 25 mg empagliflozin recipients and placebo recipients. METHODS Parallel-arm randomized controlled trials comparing the effect of daily administered 25 mg empagliflozin tablets in adjunct to insulin treatment with placebo and insulin treatment in T1DM patients with an estimated glomerular filtration rate of 45 mL/min/1.73 m2 or more were eligible for inclusion. Trials were searched in PubMed, EMBASE, SCOPUS, and CENTRAL with no restriction on date and language. Risk of bias of trials was assessed and mean and standard deviation of glycated hemoglobin (HbA1c, in %), systolic blood pressure (mmHg), and diastolic blood pressure (mmHg) at the end of the trial period were collected, and random-effects meta-analysis was done to estimate the weighted mean difference (WMD). The meta-analysis was done in Stata statistical software. This study was conducted in June 2019. RESULTS Three relatively small-sized trials published between 2015 and 2018 were eligible for review and analyses. The trials suffered from unclear risk of performance and detection bias. The HbA1c reduction favored the intervention group (WMD = -0.478, 95% confidence intervals = -0.766--0.189, P = 0.001; I2 = 0%). The WMD of blood pressure (systolic and diastolic) did not vary between the treatment groups. CONCLUSION Evidence (of moderate quality) suggests that daily administration of empagliflozin 25 mg tablets in adjunct to insulin in T1DM patients with optimum kidney functioning is useful to achieve glycemic control compared to placebo and insulin therapy. However, the effect on blood pressure remained indistinguishable between the compared interventions.

Abstract
Abstract
Introduction. The introduction of sodium glucose cotransporter 2 inhibitors in the management of diabetes was an innovation in the treatment of this disease, considering the protective cardiovascular effect not only the ability of decreasing the plasma glucose. In Europe, this class of medication is approved for the treatment of type 2 diabetes and some of them (dapagliflozin and sotagliflozin) are also approved for use in certain patients with type 1 diabetes mellitus. These patients must have inadequate control of their blood glucose levels despite optimal insulin therapy. One of the adverse effects is diabetic ketoacidosis.
Case report. This case report presents a diabetic patient whose treatment was changed from insulin therapy to oral therapy. Within 10 days after the initiation of the new treatment her condition gradually worsened and she arrived at the emergency room with nausea, vomiting and altered general condition. She was admitted for euglycemic ketoacidosis and treated according to the protocol.
Conclusions. This case reveals the importance of continuing the insulin therapy when adding a sodium glucose cotransporter 2 inhibitor in type 1 diabetes patients.

Abstract
Cardiovascular complications are the main cause of mortality in patients with diabetes, these have been associated with changes in function and expression of receptors coupled to G proteins (GPCR), which include orphan receptors which some of them tend to modify in diabetes, although others are not known, such as GPR135. For this reason, the objective of this work was to study the expression of the orphan receptor GPR135 in brain, heart, kidney, aorta, lung, spleen and liver of diabetic rats, as well as its function by the administration of siRNA (small interfering RNA) and curves to isoproterenol. Our results showed that GPR135 is expressed in all tissues analyzed and its expression is modified due to diabetes, we also observed that the responses to isoproterenol increase in diabetic rats administered with siRNA. Therefore, we conclude that the orphan receptor GPR135 is expressed in different tissues and its expression tends to be modified due to diabetes, besides that it is functional and that it seems to be coupled to Gi/o protein which has negative chronotropic and inotropic effects, therefore, we do not rule out that it participates in the cardiovascular complications associated with diabetes.

Abstract
A deficit or loss in the number of nephrons, the functional unit of the kidney, can induce compensatory growth and hyperfunction of remaining nephrons. An increase in single nephron glomerular filtration rate (SNGFR) aims to compensate but may be deleterious in the long term. The increase in SNGFR is determined by the dynamics of nephron loss, total remaining GFR, the body's excretory demand, and the functional capacity to sustain single nephron hyperfunction.

Abstract
Type 1 diabetes mellitus (T1DM) is associated with premature cardiovascular disease (CVD), but the underlying mechanisms remain poorly understood. The American Diabetes Association and the European Association for the Study of Diabetes recently updated their position statement on the management of type 2 diabetes mellitus (T2DM) to include additional focus on cardiovascular risk; improved management of risk factors in T1DM is also needed. There are important differences in the pathophysiology of CVD in T1DM and T2DM. Hyperglycaemia appears to have a more profound effect on cardiovascular risk in T1DM than T2DM, and other risk factors appear to cause a synergistic rather than additive effect, so achievement of treatment targets for all recognized risk factors is crucial to reducing cardiovascular risk. Here we discuss the evidence for addressing established cardiovascular risk factors, candidate biomarkers and surrogate measurements, and possible interventions.

Abstract
The everted gut sacs and Caco-2 cell models were used to investigate the intestinal absorptive characteristics and subcellular localization of chitobiose and chitopentaose in this study. In everted gut sacs, the absorptive pattern showed no concentration-dependent manner when the concentration was lower than 10 mM. In the presence of phlorizin (100 μM) and phloretin (100 μM), the chitobiose absorption rates decreased by (4.97 ± 0.89)% and (19.2 ± 2.77)%, and they were (10.4 ± 2.43)% and (27.5 ± 1.68)% for chitopentaose. In Caco-2 cells, the concentration showed influences similar to those with the everted gut sacs results. After adding phlorizin and phloretin in the apical side, the PappAP-BL of chitobiose and chitopentaose significantly decreased. Considering the translocation, they were enriched in endoplasmic reticulum and mitochondrion. This study indicated that concentration and active transporter were capable of mediating the absorption of chitobiose and chitopentaose, and the subcellular localization of them could help to study the mechanisms of their effects.

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
Epithelial glucose transport is accomplished by Na+ -glucose co-transporters, SGLT1 and SGLT2. In the intestine, uptake of dietary glucose is for its majority mediated by SGLT1, and humans with mutations in the SGLT1 gene show glucose/galactose malabsorption. In the kidney, both transporters, SGLT1 and SGLT2, are expressed and recent studies identified that SGLT2 mediates up to 97% of glucose reabsorption. Humans with mutations in the SGLT2 gene show familial renal glucosuria. In the last three decades, significant progress was made in understanding the physiology of these transporters and their potential as therapeutic targets. Based on the structure of phlorizin, a natural compound acting as a SGLT1/2 inhibitor, initially several SGLT2, and later SGLT1 and dual SGLT1/2 inhibitors have been developed. Interestingly, SGLT2 knockout or treatment with SGLT2 selective inhibitors only causes a fractional glucose excretion in the magnitude of ∼60%, an effect mediated by up-regulation of renal SGLT1. Based on these findings the hypothesis was brought forward that dual SGLT1/2 inhibition might further improve glycaemic control via targeting two distinct organs that express SGLT1: the intestine and the kidney. Of note, SGLT1/2 double knockout mice completely lack renal glucose reabsorption. This review will address the rationale for the development of SGLT1 and dual SGLT1/2 inhibitors and potential benefits compared to sole SGLT2 inhibition.

Abstract
The sodium-dependent glucose transporters 2 (SGLT2) plays important role in renal reabsorption of urinal glucose back to plasma for maintaining glucose homeostasis. The approval of SGLT2 inhibitors for treatment of type 2 diabetes highlights the SGLT2 as a feasible and promising drug target in recent years. Current methods for screening SGLT2 inhibitors are complex, expensive and labor intensive. Particularly, these methods cannot directly measure nonradioactive glucose uptake in endogenous SGLT2-expressing kidney cells. In present work, human kidney cells, HK-2, was incubated with a fluorescent D-glucose derivant 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy-D-glucose (2-NBDG) and the fluorescent intensity of 2-NBDG was employed to measure the amount of glucose uptake into the cells. By optimizing the passages of HK-2 cells, 2-NBDG concentration and incubation time, and by measuring glucose uptake treated by Dapagliflozin, a clinical drug of SGLT2 inhibitors, we successfully developed a new assay for measuring glucose uptake through SGLT2. The nonradioactive microplate and microscope-based high-throughput screening assay for measuring glucose can be a new method for screening of SGLT2 inhibitors and implied for other cell assays for glucose measurement extensively.

Abstract
Sodium-glucose cotransporters SGLT1 (encoded by SGLT1, also known as SLC5A1) and SGLT2 (encoded by SGLT2, also known as SLC5A2) are important mediators of epithelial glucose transport. While SGLT1 accounts for most of the dietary glucose uptake in the intestine, SGLT2 is responsible for the majority of glucose reuptake in the tubular system of the kidney, with SGLT1 reabsorbing the remainder of the filtered glucose. As a consequence, mutations in the SLC5A1 gene cause glucose/galactose malabsorption, whereas mutations in SLC5A2 are associated with glucosuria. Since the cloning of SGLT1 more than 30 years ago, big strides have been made in our understanding of these transporters and their suitability as drug targets. Phlorizin, a naturally occurring competitive inhibitor of SGLT1 and SGLT2, provided the first insights into potential efficacy, but its use was hampered by intestinal side effects and a short half-life. Nevertheless, it was a starting point for the development of specific inhibitors of SGLT1 and SGLT2, as well as dual SGLT1/2 inhibitors. Since the approval of the first SGLT2 inhibitor in 2013 by the US Food and Drug Administration, SGLT2 inhibitors have become a new mainstay in the treatment of type 2 diabetes mellitus. They also have beneficial effects on the cardiovascular system (including heart failure) and the kidney. This review focuses on the rationale for the development of individual SGLT2 and SGLT1 inhibitors, as well as dual SGLT1/2 inhibition, including, but not limited to, aspects of genetics, genetically modified mouse models, mathematical modelling and general considerations of drug discovery in the field of metabolism.

Abstract
BACKGROUND A significant portion of patients who are affected by acute kidney injury (AKI) do not fully recover due to largely unclear reasons. Restoration of tubular function has been proposed to be a prerequisite for glomerular filtration rate (GFR) recovery. SUMMARY Proximal tubular cells dedifferentiate during the tubular injury phase, which is required for subsequent cell proliferation and replacement of lost epithelial cells. Experimental studies indicate that some cells fail to redifferentiate and continue to produce growth factors (e.g., transforming growth factor β) that can induce fibrosis. Preclinical studies provide first evidence for beneficial effects of inhibiting glucose transport in the proximal tubule in models of ischemia-reperfusion injury. Comparing renal RNA sequencing data with kidney function during recovery from varying levels of AKI may provide new cues with regard to the sequence of events and help identify key determinants of recovery from AKI. Key Messages: Tubular recovery after AKI is vital for recovery of kidney function including improvement of GFR, and likely determines which patients fully recover from AKI or progress to chronic kidney disease. There is a need to better understand the sequence of events and the processes of tubular cell proliferation and repair, including safe strategies to intervene. The temporary inhibition of selected tubular transport processes, possibly in selected nephron regions, may provide an opportunity to improve tubular cell energetics and facilitate tubular cell recovery with consequences for kidney outcome.
