The incidence of diabetes is continuously increasing worldwide, resulting in a considerable socioeconomic burden. Glycemic control using traditional diabetes medications prevents microvascular complications; however, there is no objective evidence that it prevents macrovascular complications. In the 21st century, concerns have arisen that strict glycemic control and the diabetes drug rosiglitazone might increase mortality. This led the United States Food and Drug Administration to establish guidelines that require that cardiovascular outcome trials (CVOTs) with 3-point major adverse cardiovascular events (3-P MACE) as the primary endpoints be performed for new diabetes drugs. Since then, 20 CVOTs have been reported. Dipeptidyl peptidase 4 inhibitors do not increase the incidence of cardiovascular disease; however, saxagliptin increases the risk of heart failure. Sodium-glucose cotransporter inhibitors (SGLT2is) and glucagonlike peptide 1 receptor agonists (GLP-1RAs) not only have proven cardiovascular safety but also have shown results beyond expectations by reducing the incidence of cardiovascular diseases. Additionally, SGLT2is have been reported to markedly prevent heart failure and kidney disease. The reduction in 3-P MACE by GLP-1RAs was observed only with long-acting agents; long-acting GLP-1RAs also markedly reduced renal endpoints. However, no preventive effect against heart failure was observed with GLP-1RAs. The preventive effects of both drug types against cardiovascular and kidney diseases appear to be independent of glycemic control. In conclusion, based on CVOT results, it is necessary to actively prescribe SGLT2is and GLP-1RAs to prevent cardiovascular disease in patients with diabetes, regardless of glycemic control.

We investigated the potential association between ketonuria during treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors and its renoprotective effect in patients with type 2 diabetes. We included 192 patients who had received SGLT2 inhibitors for more than 6 months. After propensity score matching, 52 patients each were allocated into groups with or without ketonuria, respectively. The estimated glomerular filtration rate exhibited a significant improvement only in subjects with ketonuria (without ketonuria: mean difference, –0.02 mL/min/1.73 m2 [95% confidence interval (CI), –3.87 to 3.83 mL/min/1.73 m2] vs. with ketonuria: mean difference, 6.81 mL/min/1.73 m2 [95% CI, 3.16 to 10.46 mL/min/1.73 m2]; P

Neutropenia and elevated concentrations of hepatic transaminases often lead to referrals from emergency or outpatient departments to relevant specialists to diagnose underlying inborn errors of metabolism. Glycogen storage disease type (GSD) Ib, a rare congenital disorder of glucose metabolism caused by the SLC37A4 gene mutations, shows various manifestations, including persistent neutropenia and elevated hepatic transaminases. Empagliflozin has demonstrated its efficacy in treating GSD Ib-associated neutropenia by reducing the entry of 1,5-anhydroglucitol-6-phosphate into the neutrophils. This article reports successful empagliflozin therapy for GSD Ib-related neutropenia in 2 Korean adolescents. Diagnosing GSD Ib is complex and usually initiated by a referral from emergency or outpatient departments when there is a high index of suspicion. Once diagnosed, empagliflozin shows promising outcomes in restoring counts and function of the neutrophils without severe adverse effects in children with GSD Ib, supporting it as a safe and effective therapeutic option for GSD Ib-associated neutropenia.

Sodium glucose cotransporter 2 (SGLT2) inhibitors have emerged as powerful medications in the past decade. Numerous clinical trials have reported their cardio-renal protective effects and associated reductions in mortality. The beneficial effects of SGLT2 inhibitors in mediating heart failure and chronic kidney disease progression have been consistent across patients with and without diabetes regardless of ejection fraction. Therefore, SGLT2 inhibitors are not only antidiabetic drugs but also medications for heart failure and chronic kidney disease. However, adverse events such as genital infections and diabetic ketoacidosis should be considered. In this review, we explore the journey of SGLT2 inhibitors, often referred to as the “statins of the 21st century,” from their inception to the present day. We introduce the strengths and weaknesses of this medication and discuss unresolved issues that should be taken into considerations when prescribing SGLT2 inhibitors. [ABSTRACT FROM AUTHOR]

Sodium glucose cotransporter 2 (SGLT2) inhibitors were initially developed to enhance glycemic control in diabetic patients, but they have emerged as a promising treatment for individuals with chronic kidney disease (CKD) regardless of diabetic status. A collaborative meta-analysis of large-scale SGLT2 inhibitor trials has provided compelling evidence supporting recommendations for the use of these agents in CKD patients, regardless of their primary kidney disease diagnosis or whether they have diabetes. Notably, the kidney-protective benefits of SGLT2 inhibitors have been observed across various stages of CKD, including advanced stage 4 CKD, and across all levels of albuminuria. Given the robust evidence highlighting the benefits of SGLT2 inhibitors across a broad spectrum of CKD patients, these agents should be considered foundational therapy for CKD, in order to mitigate the progression to kidney failure and its associated complications. Although the beneficial effects of SGLT2 inhibitors may not be immediately apparent, they are expected to grow over time, potentially altering the prognosis for numerous CKD patients.

Sodium glucose cotransporter 2 (SGLT2) inhibitors, initially designed for type 2 diabetes management, have exhibited consistent efficacy across the cardiovascular disease continuum. Their benefits are experienced by patients with cardiovascular risk factors, those with established atherosclerotic cardiovascular disease, and even individuals suffering from heart failure (HF). Notably, SGLT2 inhibitors have demonstrated remarkable effectiveness in preventing and managing HF, positioning them as essential primary therapies for HF patients irrespective of their diabetic status. They have emerged as a uniquely effective treatment for HF with preserved ejection fraction, filling a therapeutic gap that previously existed in this population. These cardiovascular benefits are not limited to diabetic patients, indicating a broader potential for SGLT2 inhibitors in cardiovascular care. Their expanded indications suggest a pivotal role in both the prevention and treatment of cardiovascular disease. However, while clinical outcomes with SGLT2 inhibitors are promising, the precise mechanism underlying their cardiovascular protection remains unclear. Further research is warranted to elucidate these mechanisms, potentially unveiling new therapeutic avenues and facilitating the development of novel drugs. [ABSTRACT FROM AUTHOR]

Sodium-glucose cotransporter-2 (SGLT2) inhibitors have become increasingly prescribed because of their proven protective effects on the heart and kidneys, and carbohydrate-restricted diets are popular therapeutic approaches for patients with obesity and diabetes. A 28-year-old obese woman with recently diagnosed diabetes developed euglycemic diabetic ketoacidosis (DKA) while on dapagliflozin, an SGLT2 inhibitor, and following a carbohydrate-restricted diet. She presented with nausea, vomiting, and epigastric pain. Hospital tests showed a blood glucose of 172 mg/dL, metabolic acidosis, and increased ketone levels, confirming euglycemic DKA. Treatment involved discontinuing dapagliflozin and administering fluids, glucose, and insulin. She recovered and was discharged on the fourth day. This is considered a case of euglycemic DKA induced by SGLT2 inhibitors and triggered by a carbohydrate-restricted diet. This case highlights the importance of physicians in confirming the symptoms and laboratory results of DKA, even in patients with normal blood glucose levels taking SGLT2 inhibitors and following carbohydrate-restricted diets. It is also crucial to advise patients to maintain an adequate carbohydrate intake.

Background This study evaluated the efficacy and safety of add-on gemigliptin in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycemic control with metformin and dapagliflozin. Methods In this randomized, placebo-controlled, parallel-group, double-blind, phase III study, 315 patients were randomized to receive either gemigliptin 50 mg (n=159) or placebo (n=156) with metformin and dapagliflozin for 24 weeks. After the 24-week treatment, patients who received the placebo were switched to gemigliptin, and all patients were treated with gemigliptin for an additional 28 weeks. Results The baseline characteristics were similar between the two groups, except for body mass index. At week 24, the least squares mean difference (standard error) in hemoglobin A1c (HbA1c) changes was –0.66% (0.07) with a 95% confidence interval of –0.80% to –0.52%, demonstrating superior HbA1c reduction in the gemigliptin group. After week 24, the HbA1c level significantly decreased in the placebo group as gemigliptin was administered, whereas the efficacy of HbA1c reduction was maintained up to week 52 in the gemigliptin group. The safety profiles were similar: the incidence rates of treatment-emergent adverse events up to week 24 were 27.67% and 29.22% in the gemigliptin and placebo groups, respectively. The safety profiles after week 24 were similar to those up to week 24 in both groups, and no new safety findings, including hypoglycemia, were noted. Conclusion Add-on gemigliptin was well tolerated, providing comparable safety profiles and superior efficacy in glycemic control over placebo for long-term use in patients with T2DM who had poor glycemic control with metformin and dapagliflozin.

The latest therapeutic agent for diabetes is characterized by a longer lasting blood glucose control effect than existing treatments and stable blood glucose control. In addition, it has the advantage of being able to manage not only diabetes, but also comorbidities by considering the characteristics of each patient, such as comorbidities (atherosclerotic cardiovascular disease, chronic kidney disease, etc.). In this chapter, new antidiabetic drugs will be introduced based on the latest clinical research results on drugs such as sodium glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists.

Progress in the treatment of diabetic kidney disease (DKD) has been modest since the early trials on renin-angiotensin-aldosterone system inhibitors (RAASis). Although sodium-glucose co-transporter 2 inhibitors (SGLT2is) have revolutionized the management of DKD by lowering proteinuria and protecting organs, other novel treatment approaches with good evidence and efficacy that can be used in conjunction with a RAASi or SGLT2i in managing DKD have emerged in the past few years. This review discusses the evidence for glucagon-like peptide-1 receptor agonist, selective mineralocorticoid receptor antagonist, and selective endothelin A receptor antagonist, emerging treatment options for DKD beyond SGLT2 inhibition.

Diabetic kidney disease (DKD) is the leading cause of chronic kidney disease and end-stage kidney disease worldwide, as the obesity epidemic and the burden of diabetes continue to rise globally. In general, guideline management of patients with DKD recommends lifestyle modifications, blood pressure and glycemic control, and dyslipidemia treatment along with other cardiovascular disease risk reduction measures. The inhibition of the renin-angiotensin system (RAS) using an angiotensin-converting enzyme inhibitor or an angiotensin II receptor blocker remains the foundational therapy for DKD. In type 2 diabetes (T2D), significant advances in therapeutics, including the sodium-glucose cotransporter-2 inhibitors (SGLT2i), the glucagon-like peptide-1 receptor agonists (GLP-1 RA), and the nonsteroidal mineralocorticoid receptor agonist (MRA) finerenone, have dramatically expanded the armamentarium for treating DKD and its cardiovascular complications. Initiating, optimizing, and sustaining evidence-based pharmacological therapy using a therapeutic combination of RAS inhibitor + SGLT2i/GLP-1 RA + nonsteroidal MRA + statin is likely to significantly improve outcomes for T2D with DKD. Research into potential novel therapeutic targets for DKD remains particularly active and brings much anticipation and optimism to this field.

Background Prospective comparative studies on the effects of various antidiabetic agents on bone metabolism are limited. This study aimed to assess changes in bone mass and biochemical bone markers in postmenopausal patients with type 2 diabetes mellitus (T2DM). Methods This prospective, multicenter, open-label, comparative trial included 264 patients with T2DM. Patients who had received a metformin, or sulfonylurea/metformin combination (Group 1); a thiazolidinedione combination (Group 2); a dipeptidyl peptidase-4 inhibitor (gemigliptin) combination (Group 3); or an sodium-glucose cotransporter 2 inhibitor (empagliflozin) combination (Group 4) were prospectively treated for 12 months; bone mineral density (BMD) and bone turnover marker (BTM) changes were evaluated. Results The femoral neck BMD percentage changes were −0.79%±2.86% (Group 1), −2.50%±3.08% (Group 2), −1.05%±2.74% (Group 3), and −1.24%±2.91% (Group 4) (P

Over the last 5 years there have been many new developments in the management of diabetic kidney disease. Glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT2) inhibitors were initially used for glycemic control, but more recent studies have now shown that their benefits extend to cardiovascular and kidney outcomes. The recent addition of data on the novel mineralocorticoid receptor antagonist (MRA) gives us another approach to further decrease the residual risk of diabetic kidney disease progression. In this review we describe the mechanism of action, key studies, and possible adverse effects related to these three classes of medications. The management of type 2 diabetes now includes an increasing number of medications for the management of comorbidities in a patient population at significant risk of cardiovascular disease and progression of chronic kidney disease. It is from this perspective that we seek to outline the rationale for the sequential and/or combined use of SGLT2 inhibitors, GLP-1 RA and MRAs in patients with type 2 diabetes for heart and kidney protection.

Background To compare the renal effects of dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium-glucose cotransporter 2 (SGLT2) inhibitors on individual outcomes in patients with type 2 diabetes. Methods We searched electronic databases (MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials) from inception to June 2019 to identity eligible randomized controlled trials of DPP-4 inhibitors or SGLT2 inhibitors that reported at least one kidney outcome in patients with type 2 diabetes. Outcomes of interest were microalbuminuria, macroalbuminuria, worsening nephropathy, and end-stage kidney disease (ESKD). We performed an arm-based network meta-analysis using Bayesian methods and calculated absolute risks and rank probabilities of each treatment for the outcomes. Results Seventeen studies with 87,263 patients were included. SGLT2 inhibitors significantly lowered the risks of individual kidney outcomes, including microalbuminuria (odds ratio [OR], 0.64; 95% credible interval [CrI], 0.41 to 0.93), macroalbuminuria (OR, 0.48; 95% CrI, 0.24 to 0.72), worsening nephropathy (OR, 0.65; 95% CrI, 0.44 to 0.91), and ESKD (OR, 0.65; 95% CrI, 0.46 to 0.98) as compared with placebo. However, DPP-4 inhibitors did not lower the risks. SGLT2 inhibitors were considerably associated with higher absolute risk reductions in all kidney outcomes than DPP-4 inhibitors, although the benefits were statistically insignificant. The rank probabilities showed that SGLT2 inhibitors were better treatments for lowering the risk of albuminuria and ESKD than placebo or DPP-4 inhibitors. Conclusion SGLT2 inhibitors were superior to DPP-4 inhibitors in reducing the risk of albuminuria and ESKD in patients with type 2 diabetes.

Over the last two decades, our understanding of diabetes and treatment strategies have evolved tremendously, from scientific, mechanistic, and human perspectives. The categories of anti-diabetic medications expanded from a few to numerous, enabling clinicians to personalize diabetes care and treatment. Thanks to rapid growth in the field of science and medical engineering, newer treatment options are coming to the market with various advantages and disadvantages to be aware of. Therefore, clinicians should rapidly adopt new trends based on guidelines and data from many clinical trials in the field of diabetes. In the treatment of dyslipidemia, trends and guidelines are changing every year, and novel therapies are being developed. In this review, we would like to summarize the major achievements in clinical medicine in 2020 in the field of diabetes mellitus and dyslipidemia.

Background We assessed the glucose-lowering efficacy of adding empagliflozin versus dose escalating existing medications in patients with uncontrolled type 2 diabetes (T2D). Methods This was a 6-month retrospective case-control study in subjects with uncontrolled T2D (glycated hemoglobin [HbA1c] >7%) on conventional treatment. The study group started add-on therapy with empagliflozin (10 mg once a day) while the control group was up-titrated with existing medication, using either monotherapy or a combination of metformin, sulfonylurea, and a dipeptidyl peptidase-4 inhibitor. The primary endpoints included changes in HbA1c, fasting plasma glucose (FPG), and 2-hour postprandial glucose (PP2) levels. Secondary outcomes included changes in body composition, body mass index (BMI), and serum ketone bodies, and urinary excretion of sodium, potassium, chlorine, calcium, phosphorus, and glucose. Results After treatment, the reduction in HbA1c was significantly greater in the empagliflozin group than in controls (from 8.6%±1.6% to 7.6%±1.5% vs. 8.5%±1.1% to 8.1%±1.1%; P

Diabetes mellitus (DM) is linked to poor outcomes after cardiovascular events and renal complications. Recently, novel antidiabetic agents, such as dipeptidyl peptidase-4 inhibitors, sodium-glucose cotransporter 2 (SGLT2) inhibitors, and glucagon-like peptide-1 receptor agonists, are available. Among them, studies on SGLT2 inhibitors show favorable results both for cardiovascular and renal outcomes. SGLT2 inhibitors are well-tolerated with few side effects. Urinary tract infection has not been increased in many studies of SGLT2 inhibitors. The most frequent side-effect associated with SGLT2 inhibitors is mycotic infections in the genital area. Fortunately, these are generally mild in severity and easily treated with antibiotics. Hypoglycemia can occur when an SGLT2 inhibitor is added to sulfonylureas or insulin. Volume depletion and hypotension can be minimized by adjusting diuretics or other antihypertensive agents. Of note, acute kidney injury was observed in a few studies with SGLT2 inhibitors. However, in more recent observational studies, acute kidney injury was less frequently observed in conjunction with SGLT2 inhibitor treatment. An increased incidence of lower extremity amputation and fractures was observed in a large study with canagliflozin but not with other SGLT2 inhibitors. In conclusion, it is critical to understand the benefits and risks associated with use of SGLT2 inhibitors. [ABSTRACT FROM AUTHOR]

The basic action mechanism of sodium-glucose cotransporter 2 (SGLT2) inhibitor is to lower the glucose burden by excreting the glucose filtered by the kidney into the urine. Although SGLT2 inhibitors are primarily indicated as glucose-lowering agents, they have a broad range of effects on renal function and plasma volume homeostasis, as well as on adiposity and energy metabolism across the entire body. That might be why SGLT2 inhibition causes spill-over of sodium and glucose beyond the proximal tubule, triggering dynamic and reversible realignment of energy metabolism, renal filtration, and plasma volume. A better understanding of SGLT2 inhibition in the kidney and the entire body will lead to more benefits in people with and without diabetes. [ABSTRACT FROM AUTHOR]

The prevalence of non-alcoholic fatty liver disease (NAFLD) has sharply increased over the past several decades in Korea. In most cases of NAFLD, metabolic stress and cellular apoptosis are often driven by metabolic abnormality, eventually leading to inflammation and fibrosis . Along with a dramatic surge in the obesity epidemic, 10-20% of NAFLD patients ultimately progress to non-alcoholic steatohepatitis (NASH), a precursor to cirrhosis and hepatocellular carcinoma, as well as multi-organ systemic diseases. Currently, diet and exercise are chiefly recommended to achieve significant weight loss and improve metabolic dysfunction in patients with NAFLD. However, weight loss remains to be an elusive goal for both clinical practitioners and NAFLD patients. To date, although there has not been any proven pharmacotherapy against NAFLD, numerous promising pipelines with good target engagement are under development. Moreover, given the global landmark phase 3 trials using obeticholic acid (a farnesoid X receptor agonist, REGENERATE trial) and elafibranor (a dual peroxisome proliferator-activated receptor α/δ agonist, RESOLVE-IT trial), the era of specific target therapies focusing on molecular and metabolic pathogenesis of NASH and fibrosis is near at hand. In this paper, we briefly cover the current and future therapeutic options in patients with NAFLD across the entire spectrum of diseases.
