Diabetes mellitus is associated with abnormal bone health and an increased risk of fracture even though patients have normal or higher BMD. The mechanisms behind diabetes mellitus- induced various skeletal disorders remain unclear. Anti-diabetic drugs may have negative or positive impact on bone metabolism. For instance, thiazolidinediones increases the bone loss and risk of fracture possibly through PPARγ activation in bone marrow cells and hamper osteoblastogenesis via decreasing Runx2 transcription factor, IGF-1 and Wnt signalling pathways...

Liver X receptors (LXRs) are members of a nuclear receptor family consisting of two isoforms, LXR-α and LXR-β. They play a major role in energy metabolism including lipid and glucose metabolism. Recent studies reported LXRs regulate plasma glucose although the mechanism is still uncertain. The present study investigated whether LXR activation regulates sodium glucose cotransporter2 (SGLT2) in human renal proximal tubular cells. LXR agonists, T0901317 and GW3965, inhibited SGLT2-mediated glucose uptake in concentration-dependent manners...

About 50% of all patients suffering from heart failure (HF) exhibit a reduced ejection fraction (EF ≤ 40%), termed HFrEF. The others may be classified into HF with midrange EF (HFmrEF 40-50%) or preserved ejection fraction (HFpEF, EF ≥ 50%). Presentation and pathophysiology of HFpEF is heterogeneous and its management remains a challenge since evidence of therapeutic benefits on outcome is scarce. Up to now, there are no therapies improving survival in patients with HFpEF. Thus, the treatment targets symptom relief, quality of life and reduction of cardiac decompensations by controlling fluid retention and managing risk factors and comorbidities...

BACKGROUND: In patients with diabetes mellitus (DM) there is a clear association between blood pressure (BP) levels and macrovascular and microvascular complications. However, the BP targets that need to be achieved for optimal outcomes remain controversial. METHODS: The purpose of this narrative review is to discuss BP targets and management in patients with DM. The subject of elevated heart rate, which has been associated with mortality in many populations, and which is observed in some patients with DM will also be addressed...

Introduction Novelties in the management of type 2 diabetes are dominated by the commercialisation of new glucose-lowering agents, which offer alternatives to older antidiabetic medications, and by the publication of several prospective placebo-controlled outcome trials, which demonstrated not only cardiovascular safety but also cardiovascular and renal protection with some new medications. Areas covered Updates regarding the use of glucose-lowering agents are discussed from a clinical point of view. Some new viewpoints concern older antidiabetic agents such as metformin, sulfonylureas and glitazones whose benefit-risk balance has been revisited, especially in high risk patients...

OBJECTIVES: Diabetes mellitus is often associated with a number of complications such as nephropathy, neuropathy, retinopathy and foot ulcers. However, weak bone is a diabetic complication that is often overlooked. Although the exact mechanism for weak bones within diabetes mellitus is unclear, studies have shown that the mechanism does differ in both type I (T1DM) and type II diabetes (T2DM). This review, however, investigates the application of mesenchymal stem cells, recombinant human bone morphogenetic protein-2, teriparatide, insulin administration and the effectiveness of a peroxisome proliferator-activated receptor-ϒ modulator, netoglitazone in the context of diabetic weak bones...

Canagliflozin (CAN) is a sodium-glucose co-transporter 2 (SGLT2) inhibitor indicated to improve glycemic control in adults with type 2 diabetes mellitus. There is a little information about its effect on the cholinergic system that proposed mechanism for memory improvement occurring by SGLT2 drugs. This study aimed to estimate the effect of CAN as compared to galantamine (GAL) treatments for two weeks on scopolamine hydrobromide (SCO)-induced memory dysfunction in experimental rats. Animals divided into six groups; control (CON), CAN, GAL, SCO, SCO + CAN and SCO + GAL...

In Brief Sodium-glucose cotransporter 2 (SGLT2) inhibitors and incretin-based therapies (dipeptidyl peptidase-4 [DPP-4] inhibitors and glucagon-like peptide-1 [GLP-1] receptor agonists) are widely used to treat patients with type 2 diabetes. In clinical and real-world studies, canagliflozin, an SGLT2 inhibitor, has demonstrated superior A1C lowering compared to the DPP-4 inhibitor sitagliptin. Canagliflozin can also promote modest weight/fat loss and blood pressure reduction. The addition of canagliflozin to treatment regimens that include a DPP-4 inhibitor or a GLP-1 receptor agonist has been shown to further improve glycemic control, while still maintaining beneficial effects on cardiometabolic parameters such as body weight and blood pressure...

Two clinical trials demonstrate the superiority versus a placebo of two antidiabetic drugs in patients with type 2 diabetes and high cardiovascular risk. Empagliflozin, an inhibitor of sodium-glucose type 2 (SGLT2) cotransporters, in EMPA-REG OUTCOME, and liraglutide, an agonist of glucagon-like peptide-1 (GLP-1) receptors, in LEADER, showed a significant reduction in major cardiovascular events (- 14 and - 13 %, respectively), cardiovascular mortality (- 38 and - 22 %, respectively) and all-cause mortality (- 32 and - 15 %, respectively)...

Canagliflozin, an inhibitor of sodium glucose co-transporter (SGLT) 2, has been shown to reduce body weight during the treatment of type 2 diabetes mellitus (T2DM). In this study, we sought to determine the role of canagliflozin in body weight loss and liver injury in obesity. C57BL/6J mice were fed a high-fat diet to simulate diet-induced obesity (DIO). Canagliflozin (15 and 60 mg/kg) was administered to DIO mice for 4 weeks. Orlistat (10 mg/kg) was used as a positive control. The body weight, liver weight, liver morphology, total cholesterol (TC) and triglyceride (TG) levels were examined...

Heart failure is a disease with a high prevalence and incidence. New therapeutic approaches are needed to prevent the onset of heart failure and to reduce the high morbidity and mortality associated with this disease. An optimized therapy of arterial hypertension in patients with risk factors and the use of the SGLT2 inhibitor empagliflozin in type 2 diabetics are proven strategies to prevent heart failure. The therapeutic options in heart failure with preserved ejection fraction are still insufficient. In heart failure with reduced ejection fraction sacubitril/valsartan, the first approved angiotensin receptor-neprilysin inhibitor, is superior to an angiotensin converting enzyme (ACE) inhibitor...

Type 2 diabetes therapy has expanded considerably over the last decade. Two anti-diabetic therapeutic groups, which are GLP-1 (glucagon-like peptide-1) receptor agonists and SGLT2 inhibitors (sodium-glucose co-transporter-2), have shown efficacy not only on glycemic control but also on weight and other parameters that will be detailed in this article. Cardiovascular safety studies for two of these molecules were shown for the first time to decrease overall and cardiovascular mortality. The combination of these two therapeutic classes provides a logical solution due to their different mechanisms of action...

The U.S. Food and Drug Administration (FDA) issued a diabetes guidance in 2008 mandating that all new antidiabetes drugs rule out excess cardiovascular (CV) risk, defined as an upper bound of the two-sided 95% CI for major adverse CV events (MACE) of less than 1.80 preapproval and 1.30 postapproval. Over 25 large, prospective, randomized, controlled clinical trials involving nearly 195,000 subjects thus far have been completed or are ongoing in accordance with this guidance. The results of seven trials have been presented so far-three with dipeptidyl peptidase 4 inhibitors, one with a sodium-glucose cotransporter 2 (SGLT2) inhibitor, and three with glucagon-like peptide 1 receptor agonists (GLP-1 RA)...

Growing attention has been focused on the roles of the proximal tubules (PTs) of the kidney in glucose metabolism, including the mechanism of regulation of gluconeogenesis. In this study, we found that PT-specific insulin receptor substrate 1/2 double-knockout mice, established by using the newly generated sodium-glucose cotransporter 2 (SGLT2)-Cre transgenic mice, exhibited impaired insulin signaling and upregulated gluconeogenic gene expression and renal gluconeogenesis, resulting in systemic insulin resistance...

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a class of antidiabetic drug used for the treatment of diabetes. These drugs are thought to lower blood glucose by blocking reabsorption of glucose by SGLT2 in the proximal convoluted tubules of the kidney. To investigate the effect of inhibiting SGLT2 on pancreatic hormones, we treated perfused pancreata from rats with chemically induced diabetes with dapagliflozin and measured the response of glucagon secretion by alpha cells in response to elevated glucose...

Patients with type 2 diabetes (T2D) have an increased risk of stroke compared with people without diabetes. However, the effects of glucose-lowering drugs on risk of ischaemic stroke in T2D have been less extensively investigated than in coronary heart disease. Some evidence, including the UKPDS, has suggested a reduced risk of stroke with metformin, although the number of studies is limited. Inhibition of the KATP channels increases ischaemic brain lesions in animals. This is in agreement with a recent meta-analysis showing an increased risk of stroke with sulphonylureas vs...

Diabetic kidney disease (DKD) is the most common cause of end stage renal disease. The comprehensive management of DKD depends on combined target-therapies for hyperglycemia, hypertension, albuminuria, and hyperlipaemia, etc. Sodium-glucose co-transporter 2 (SGLT2) inhibitors, the most recently developed oral hypoglycemic agents acted on renal proximal tubules, suppress glucose reabsorption and increase urinary glucose excretion. Besides improvements in glycemic control, they presented excellent performances in direct renoprotective effects and the cardiovascular (CV) safety by decreasing albuminuria and the independent CV risk factors such as body weight and blood pressure, etc...

AIM: SGLT2 inhibitors reduce renal glucose uptake through an insulin-independent mechanism. They also increase glucagon concentration, although the extent to which this is due to a direct effect on pancreatic alpha cells remains unclear. METHODS: In the present work, αTC1 cells treated with the SGLT2 inhibitor dapagliflozin (Dapa) were analyzed for glucose transporters, molecular mediators of hormone secretion, glucagon and GLP-1 release, and the effects of somatostatin...
