Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT-2) inhibitors are a relatively novel class of oral medications for the treatment of Type 2 DM with a generally acceptable safety profile. However, these agents have been associated with rare events of a serious and potentially life-threatening complication named euglycemic diabetic ketoacidosis (euDKA). euDKA is not identical with the typical diabetic ketoacidosis, as it often presents with serious metabolic acidosis but only mild to moderate glucose and anion gap elevation. CASE PRESENTATION We report a case of a 51-year old female with Type 2 DM treated with an SGLT-2 inhibitor, developing severe metabolic acidosis with only mild blood glucose elevation after a routine surgery. A careful evaluation of involved factors led to the diagnosis of euDKA, followed by cautious application of simple therapeutic measures that resulted in complete restoration of acidosis and glycemic control in less than 48-h. CONCLUSIONS Euglycemic ketoacidosis is a rare but rather serious complication of SGLT-2 inhibitors use, often with a multifactorial etiology. Its atypical presentation requires a high level of awareness by physicians as early recognition of this complication can quickly and safely restore acid-base balance.

Glucagon-Like Peptide 1 Receptor Agonists and Heart Failure: The Need for Further Evidence Generation and Practice Guidelines Optimization.
Khan, MS, Fonarow, GC, McGuire, DK, Hernandez, AF, Vaduganathan, M, Rosenstock, J, Handelsman, Y, Verma, S, Anker, SD, McMurray, JJV, et al
Circulation. 2020;(12):1205-1218
Abstract
With worsening epidemiological trends for both the incidence and prevalence of type 2 diabetes mellitus (T2DM) and heart failure (HF) worldwide, it is critical to implement optimal prevention and treatment strategies for patients with these comorbidities, either alone or concomitantly. Several guidelines and consensus statements have recommended glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter type 2 inhibitors as add-ons to lifestyle interventions with or without metformin in those at high atherosclerotic cardiovascular disease risk. However, these recommendations are either silent about HF or fail to differentiate between the prevention of HF in those at risk versus the treatment of individuals with manifest HF. Furthermore, these documents do not differentiate among those with different HF phenotypes. This distinction, even though important, may not be critical for sodium-glucose cotransporter type 2 inhibitors in view of the consistent data for benefit for both atherosclerotic cardiovascular disease- and HF-related outcomes that have emerged from the regulatory-mandated cardiovascular outcome trials for all sodium-glucose cotransporter type 2 inhibitors and the recent DAPA-HF trial (Dapagliflozin in Patients with Heart Failure and Reduced Ejection Fraction)demonstrating the benefit of dapagliflozin on HF-related outcomes in patients with HF with reduced ejection fraction with or without T2DM. However, the distinction may be crucial for glucagon-like peptide-1 receptor agonists and other antihyperglycemic agents. Indeed, in several of the new statements, glucagon-like peptide-1 receptor agonists are suggested treatment not only for patients with T2DM and atherosclerotic cardiovascular disease, but also in those with manifest HF, despite a lack of evidence for the latter recommendation. Although glucagon-like peptide-1 receptor agonists may be appropriate to use in patients at risk for HF, mechanistic insights and observations from randomized trials suggest no clear benefit on HF-related outcomes and even uncertainty regarding the safety in those with HF with reduced ejection fraction. Conversely, theoretical rationales suggest that these agents may benefit patients with HF with preserved ejection fraction. Considering that millions of patients with T2DM have HF, these concerns have public health implications that necessitate the thoughtful use of these therapies. Achieving this aim will require dedicated trials with these drugs in both patients who have HF with reduced ejection fraction and HF with preserved ejection fraction with T2DM to assess their efficacy, safety, and risk-benefit profile.

Dapagliflozin and cardiovascular outcomes in patients with Type 2 diabetes.
Al-Bazz, DY, Wilding, JP
Future cardiology. 2020;(2):77-88
Abstract
The relationship between cardiovascular disease, heart failure (HF) and Type-2 diabetes (T2DM) is widely recognized. Cardiovascular (CV) outcome trials are required for all new glucose-lowering agents to confirm safety with respect to CV risk. CV outcome trials with SGLT2i inhibitors have shown CV benefit, with reductions in major CV events and HF. This review focuses on the DECLARE-TIMI 58 trial with dapagliflozin in T2DM, which showed noninferiority for major adverse cardiovascular events and reduction in hospitalization for HF and associated CV mortality in a broad range of patients with T2DM. The DAPA-HF trial of dapagliflozin in people with HF with reduced ejection fraction with and without T2DM confirms benefits for those with HF.

United States Pharmacopeia Safety Review of Willow Bark.
Oketch-Rabah, HA, Marles, RJ, Jordan, SA, Low Dog, T
Planta medica. 2019;(16):1192-1202
Abstract
Willow bark (Salix spp.) is an ingredient in some dietary supplements. No serious adverse effects were reported from trials of willow bark extracts delivering 120 - 240 mg salicin (the purported active constituent) daily for up to 8 weeks. All studies involved adults only; none involved special subpopulations such as pregnant or breastfeeding women, or children. The most common adverse effects associated with willow bark are gastrointestinal; a few allergic reactions were also reported. Some publications advise caution when taking willow bark. There is a risk of increased bleeding in vulnerable individuals, salicylates cross the placenta and are eliminated slowly in newborns, some persons are sensitive or allergic to aspirin, and children are at risk of Reye syndrome. Concurrent use with other salicylate-containing medicines increases these risks. Metabolism of 240 mg salicin from willow bark could yield 113 mg of salicylic acid, yet dietary supplement products are not required to be labeled with warnings. In contrast, over-the-counter low-dose aspirin (81 mg strength), which delivers 62 mg salicylic acid, is required by law to include cautions, warnings, and contraindications related to its use in pregnant and nursing women, children, and other vulnerable subpopulations, e.g., those using anticoagulants. In the interest of protecting public health, the United States Pharmacopeia has included a cautionary labeling statement in the United States Pharmacopeia Salix Species monograph as follows: "Dosage forms prepared with this article should bear the following statement: 'Not for use in children, women who are pregnant or nursing, or by persons with known sensitivity to aspirin.'".

A complete review of empagliflozin: Most specific and potent SGLT2 inhibitor used for the treatment of type 2 diabetes mellitus.
Chawla, G, Chaudhary, KK
Diabetes & metabolic syndrome. 2019;(3):2001-2008
Abstract
Sodium-glucose co-transporter 2 (SGLT2) inhibitors are the latest class of drugs to be introduced for the treatment of type 2 diabetes mellitus (T2DM). They reduce hyperglycemia by increasing urinary glucose excretion and exert favorable effects beyond glucose control with consistent body weight, blood pressure, and serum uric acid reductions. Empagliflozin is a potent SGLT2 inhibitor used to improve glycemic control in adults with T2DM. It has the highest SGLT2 specificity among all the clinically used or currently tested SGLT2 inhibitors. Low risk of hypoglycemia, absence of weight gain and demonstrated cardiovascular risk reduction support its consideration as a first line medication in addition to metformin for patients with T2DM and cardiovascular disease. Mostly reported adverse events are genital mycotic infections, while urinary tract infections and events linked to volume depletion are rather rare. This review covers the complete information on empagliflozin including the history of its development, synthesis, pharmacology and different methods which have been reported for its analysis.

Novel Antidiabetic Therapies and Cardiovascular Risk Reduction: The Role of the Noninferiority Trial.
Thompson, J, Schacht, S, Rothenberg, F
Cardiology clinics. 2019;(3):335-343
Abstract
Diabetes is a major risk factor for cardiovascular disease, yet until now treatments for diabetes had only a modest impact on cardiovascular events. New interventions for patients with type 2 diabetes mellitus (oral empagliflozin and injectable liraglutide) are associated with unprecedented reductions in composite cardiovascular outcomes that seem disproportionate to the impact on glycated hemoglobin. This review examines in detail the recent trials that arrived at these conclusions, limitations of these studies, and how these outcomes may influence patient management in the future.

Effect of empagliflozin beyond glycemic control: Cardiovascular benefit in patients with type 2 diabetes and established cardiovascular disease.
Monteiro, P, Aguiar, C, Matos, P, Silva-Nunes, J, Birne, R, Branco, P, Calado, J, Melo, M, Polónia, J
Revista portuguesa de cardiologia. 2019;(10):721-735
Abstract
The prevalence of type 2 diabetes (T2D) continues to increase, and its association with cardiovascular (CV) disease has led to the inclusion of CV endpoints in clinical trials on the treatment of T2D. This article explores the various trials already performed and under development in this field, with particular focus on the EMPA-REG OUTCOME trial. In this trial, empagliflozin, a sodium-glucose co-transporter 2 inhibitor, demonstrated a reduction in CV risk in patients with T2D and established CV disease, in addition to CV safety and a decrease in glycated hemoglobin. This represents a paradigm shift that has led to changes in the international guidelines for the treatment of T2D. These results were maintained in subsequent subgroup analysis for heart failure, chronic kidney disease and peripheral arterial disease, although there are many questions concerning the mechanisms involved in these effects, including whether they are hemodynamic, metabolic or due to decreased myocardial cytoplasmic sodium concentrations. With this reduction in risk for major CV events in patients with T2D, the EMPA-REG OUTCOME trial demonstrated CV protection from a hypoglycemic drug for the first time, and opened a new era in the treatment and management of T2D. This study has led to the development of ongoing trials that will establish which patients will benefit most from this therapy, particularly with regard to comorbidities.

Dapagliflozin/Saxagliptin Fixed-Dose Tablets: A New Sodium-Glucose Cotransporter 2 and Dipeptidyl Peptidase 4 Combination for the Treatment of Type 2 Diabetes.
Coppenrath, VA, Hydery, T
The Annals of pharmacotherapy. 2018;(1):78-85
Abstract
OBJECTIVE To review the pharmacology, pharmacokinetics, efficacy, safety, and place in therapy of the fixed-dose combination (FDC) product, QTERN (dapagliflozin/saxagliptin) tablets. DATA SOURCES Searches of MEDLINE (1946 to July 1, 2017) were conducted using the keywords QTERN, saxagliptin, and dapagliflozin. Additional data were obtained from the prescribing information, the product dossier, and Clinicaltrials.gov . STUDY SELECTION AND DATA EXTRACTION All English language articles related to pharmacology, pharmacokinetics, efficacy, or safety of the combination therapy in human subjects were reviewed. DATA SYNTHESIS The pharmacokinetics of saxagliptin and dapagliflozin were not affected significantly when administered as an FDC product. Saxagliptin may suppress the increased secretion of glucagon associated with dapagliflozin. The combination dapagliflozin/saxagliptin has been studied as add-on therapy to metformin in patients with uncontrolled type 2 diabetes mellitus (T2DM). The difference in hemoglobin A1C (A1C) between saxagliptin + dapagliflozin + metformin (triple therapy) and saxagliptin + metformin was -0.59 (95% CI = -0.81 to -0.37, P < 0.0001), and the difference between triple therapy and dapagliflozin + metformin was -0.27 (95% CI = -0.48 to -0.05, P = 0.0166). The combination was well tolerated when added to metformin. CONCLUSION QTERN (dapagliflozin/saxagliptin) tablets are a reasonable option for patients with T2DM not controlled on metformin, but cost, insurance coverage, and a lackluster reduction in A1C will likely limit its use until more data regarding its effects on complications of diabetes and cardiovascular outcomes become available.

Abstract
AIM: To evaluate the safety and tolerability of dapagliflozin, a highly selective sodium-glucose co-transporter-2 inhibitor, in patients with type 2 diabetes mellitus (T2DM). METHODS Data were pooled from 13 placebo-controlled trials of up to 24 weeks' duration (dapagliflozin, n = 2360; placebo, n = 2295). Larger placebo-/comparator-controlled pools of 21 (≤208 weeks; dapagliflozin, n = 5936; control, n = 3403) and 30 trials (≥12 weeks; dapagliflozin, n = 9195; control, n = 4629) assessed the rare adverse events (AEs) of diabetic ketoacidosis (DKA) and lower limb amputation, respectively. RESULTS Over 24 weeks, the overall incidence of AEs and serious AEs (SAEs) was similar for dapagliflozin and placebo: 60.0% vs 55.7% and 5.1% vs 5.4%, respectively. Rates of hypoglycaemia, volume depletion AEs, urinary tract infections (UTIs) and fractures were balanced between the groups. Genital infections were more frequent with dapagliflozin (5.5%) vs placebo (0.6%) and renal function AEs occurred in 3.2% vs 1.8% of patients (the most common renal AE was decreased creatinine clearance: 1.1% vs 0.7%). In the 21-study pool, 1 SAE of DKA and 3 AEs of ketonuria/metabolic acidosis occurred with dapagliflozin vs none with control; estimated combined incidence for these events was 0.03% (95% confidence interval 0.010-0.089). In the 30-study pool, lower limb amputation occurred in 8 (0.1%) and 7 (0.2%) patients receiving dapagliflozin and control, respectively. CONCLUSION The overall incidence rates of AEs and SAEs were similar in the dapagliflozin and placebo/control groups, including the incidence of hypoglycaemia, volume depletion, fractures, UTIs, amputations and DKA. Genital infections were more frequent with dapagliflozin than placebo.
