Sotagliflozin, a dual SGLT1 and SGLT2 inhibitor: In the heart of the problem

A Randomized Crossover Trial of Mixed Meal Tolerance Test Response in People with Type 1 Diabetes on Insulin Pump Therapy and YG1699 or Dapagliflozin

YG1699 is a novel inhibitor of sodium-glucose cotransporter 1 (SGLT1) and SGLT2. This double-blind, 3-way crossover trial compared YG1699 to dapagliflozin as an adjunct to insulin in people with type 1 diabetes (T1D) on insulin pump therapy. Treatment periods included four mixed meal tolerance tests (MMTTs) and insulin withdrawal tests per person. Nineteen adults with T1D were randomized to YG1699 10 mg, YG1699 25 mg, and dapagliflozin 10 mg once daily for 1 week in different orders. The primary end point was the difference in area under the curve (AUC) in plasma glucose (AUC0-120min) after an MMTT between treatment groups. Mean change in plasma glucose after an MMTT (AUC0-120min) was lower for YG1699 10 mg vs. dapagliflozin (89.51% of baseline vs. 102.13%, 90% confidence interval (CI) vs. dapagliflozin, -6% to -16%, P = 0.0003) and for YG1699 25 mg (84.83% vs. 102.13%, 90% CI vs. dapagliflozin -13% to -22%, P < 0.0001). At 120 minutes, mean glucose values on no treatment, dapagliflozin, YG1699 10 mg, and YG1699 25 mg were 149 (SE 7.6), 141 (SE 6.1), 128 (SE 6.9), and 115 (SE 7.8) mg/dL, respectively. Insulin dose requirements were lower for YG1699 10 mg and 25 mg vs. dapagliflozin for bolus insulin, and for YG1699 10 mg vs. dapagliflozin for total daily insulin. Safety profiles were similar between treatment groups. YG1699 reduced post-prandial glucose more than dapagliflozin in people with T1D on insulin pump therapy. The results were consistent with dual SGLT1/SGLT2 inhibition by YG1699.

A New Age for Secondary Prevention: Optimal Medical Therapy for Stable Ischemic Heart Disease Among Patients with Diabetes and/or Obesity

Patients with type 2 diabetes and/or obesity and established cardiovascular disease are at increased risk for recurrent cardiovascular events. The indications of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors have been expanded in the last decade due to benefit in cardiovascular outcome trials and are now considered guideline-recommended therapy for patients with type 2 diabetes and cardiovascular disease. Emerging data have begun to suggest that GLP-1RAs can decrease major adverse cardiovascular events among patients with obesity without diabetes. Overall, prescription of these agents remains low, despite being key to improve disparities in recurrent cardiovascular events. In this review, we discuss optimal medical therapy for secondary prevention for stable ischemic heart disease.

Cardiometabolic effects of SGLT2 inhibitors on polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a complex endocrinopathy affecting many women of reproductive age. Although its physiology is poorly understood, hyperandrogenemia and insulin resistance play a pivotal role in this complex syndrome, predisposing patients to a variety of cardiovascular and metabolic modalities. Current therapeutic options, including lifestyle modifications and medications, often do not satisfactorily improve clinical outcomes. SGLT2 inhibitors (SGLT-2i) are a novel option which can potentially improve many hormonal and metabolic parameters for patients with PCOS, though the net cardiovascular effects remain under investigation in this population of patients with PCOS. Overall, the use of SGLT-2i may be associated with beneficial somatometric, metabolic and hormonal outcomes of PCOS. To date, all available studies have recorded body mass index, waist and hip circumference, and fat mass reductions, improved insulin and androgen levels, and reduced blood pressure. The aim of the present review is to summarise PCOS-related manifestations and mechanisms leading to cardiovascular disease, to explore the cardiometabolic impact of SGLT2i on PCOS, and to critically analyse the cardiometabolic and hormonal outcomes of the recent studies on the use of SGLT2i in women with PCOS.

Sotagliflozin vs Dapagliflozin: A Systematic Review Comparing Cardiovascular Mortality

After the debut of the results of the effect of Sotagliflozin on Cardiovascular Events in Patients with Type 2 Diabetes Post Worsening Heart Failure (SOLOIST-WHF) and Sotagliflozin in Patients With Chronic Kidney Disease and Type 2 Diabetes (SCORED) trials at the American Heart Association's 2020 Scientific session, sotagliflozin became the first drug and the third sodium glucose co-transporter-2 (SGLT-2) inhibitor to be approved for heart failure (HF) across the spectrum of ejection fraction (EF). In light of this recent major U.S. Food and Drug Administration (FDA) approval of sotagliflozin, we conducted a systematic review to compare the cardiovascular mortality rates between sotagliflozin and dapagliflozin in patients with HF. To find relevant articles, we extensively searched major research literature databases and search engines such as PubMed, MEDLINE, PubMed Central, Google Scholar, Embase, and Cochrane Library. We compared the results of significant trials involving sotagliflozin with the trials studying dapagliflozin to provide comprehensive mortality results of both drugs. The results showed that the timely initiation of sotagliflozin in HF cases significantly reduces cardiovascular mortality, hospitalizations, and urgent HF visits. Comparative trials with dapagliflozin indicate enhanced mortality reduction associated with greater initial symptom burden. The results of these major trials cannot be overlooked due to the large size of the combined trials, the randomized design, and the high standards with which they were conducted. The pathophysiology behind the cardioprotection offered by these agents is complex and multifactorial, but it is believed that due to the diuretic-like function, SGLT-2 inhibitors reduce glycemic-related toxicity, promote ketogenesis, and exert antihypertrophic, antifibrotic, and anti-remodeling properties. The benefits of dapagliflozin on cardiovascular death and worsening HF in patients with mildly reduced or preserved EF appeared especially pronounced in those with a greater degree of symptomatic impairment at baseline. Sotagliflozin led to a rise in the count of days patients were alive and not hospitalized (DAOH), which offers an extra patient-centered measure to assess the impact of the disease burden. The data in our article will help future researchers conduct large-scale trials with sotagliflozin to identify and implement it in the treatment of patients with HF as a mortality-reducing drug and to improve the quality of life for patients with HF.

SGLT-2 Inhibitors and the Inflammasome: What's Next in the 21st Century?

The nucleotide-binding domain-like receptor protein 3 (NLRP3) inflammasome in the kidney and the heart is increasingly being suggested to play a key role in mediating inflammation. In the kidney, NLRP3 activation was associated with the progression of diabetic kidney disease. In the heart, activation of the NLRP3 inflammasome was related to the enhanced release of interleukin-1β (IL-1β) and the subsequent induction of atherosclerosis and heart failure. Apart from their glucose-lowering effects, SGLT-2 inhibitors were documented to attenuate activation of the NLRP3, thus resulting in the constellation of an anti-inflammatory milieu. In this review, we focus on the interplay between SGLT-2 inhibitors and the inflammasome in the kidney, the heart and the neurons in the context of diabetes mellitus and its complications.

Probiotic and resveratrol normalize GLP-1 levels and oxidative stress in the intestine of diabetic rats

Background

Recently, the use of incretins has been considered as a therapeutic target for diabetes. One of the important incretins in the improvement of diabetes is glucagon-like peptide (GLP-1), which is secreted by the gut and reduces the apoptosis of pancreatic β-cells and improves insulin sensitivity. In this experiment we determined the effects of resveratrol and probiotics on insulin resistance, oxidative stress, and GLP-1 in type 2 diabetes (T2D) rats.

Methods

In this study, 40 male Wistar male rats were divided into 5 groups: 1. Control group, 2. T2D, 3. T2D treated with probiotics, 4. T2D treated with resveratrol, 5. T2D group treated with probiotics and resveratrol. After four weeks, the intestine were removed for histopathological analysis, biochemical tests, and oxidative stress markers.

Results

Probiotics and resveratrol significantly decreased (p < 0.001) glucose and insulin resistance, and increased (p < 0.001) GLP1 and total antioxidant capacity compared to the diabetic group. Treatment with probiotics and resveratrol also returned intestinal histological changes in diabetic rats to normal.

Conclusion

Resveratrol and probiotics appear to be effective in controlling T2D by increasing GLP-1 levels and reducing oxidative stress.
