Abstract
INTRODUCTION Patients with type 2 diabetes (T2DM) are at high risk of atherosclerotic cardiovascular disease (ASCVD) and cardiovascular death. Cardiovascular protection is a key objective in T2DM. AREAS COVERED Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have proven their efficacy in reducing major cardiovascular events in high-risk patients with T2DM in placebo-controlled trials, a finding confirmed in observational studies compared with other glucose-lowering agents. Overall, GLP-1RAs have a good safety profile associated with a favorable benefit/risk ratio for the management of T2DM, even if their cost-effectiveness might be questionable. International guidelines recommend GLP-1RAs as preferred glucose-lowering agents in patients with ASCVD and as a valuable alternative in overweight/obese patients with T2DM. However, real-life studies worldwide revealed that only a minority of patients receive a GLP-1RA, despite a positive trend for increased prescriptions in recent years. Surprisingly, however, fewer patients with established ASCVD are treated with these cardioprotective antihyperglycemic agents versus patients without ASCVD. EXPERT OPINION The reasons for GLP-1RA underuse in clinical practice are multiple. Multifaceted and coordinated interventions targeting all actors of the health-care system must be implemented to stimulate the adoption of GLP-1RAs as part of routine cardiovascular care among patients with T2DM, especially in those with ASCVD.

Cardiovascular protection significantly depends on HbA1c improvement with GLP-1RAs but not with SGLT2 is in type 2 diabetes: A narrative review. DIABETES & METABOLISM 2024; 50:101508.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is), while developed as antihyperglycaemic medications for the treatment of type 2 diabetes, have proven to reduce major cardiovascular adverse events (MACEs) and hospitalization for heart failure (especially for SGLT2is) in dedicated cardiovascular outcome trials. The contribution of the glucose-lowering effect in the cardiovascular protection is uncertain and may differ between the two drug classes. METHODS This narrative review compares the relative effects of glycated hemoglobin (HbA1c) reduction on the cardiovascular protection provided by GLP-1RAs and SGLT2is in placebo-controlled cardiovascular outcome trials by using the results of either post-hoc mediation analyses or meta-regression studies. RESULTS Both mediation and meta-regression analyses suggest that the lower cardiovascular risk with GLP-1RAs partially but substantially tracks with their glucose-lowering effect, especially when considering the reduction in nonfatal strokes. In contrast, similar analyses fail to demonstrate any significant contribution of the glucose-lowering effect with SGLT2is, not only on MACEs but also on heart failure issues. CONCLUSION The contribution of improved glucose control in cardiovascular protection is limited, but is much greater for GLP-1RAs than for SGLT2is. Of note, such mediation or meta-regression analyses are exploratory and can only be viewed as hypothesis generating.

Do SGLT2 inhibitors and GLP-1 receptor agonists modulate differently the risk of stroke ? Discordance between randomised controlled trials and observational studies. DIABETES & METABOLISM 2023; 49:101474. [PMID: 37678760 DOI: 10.1016/j.diabet.2023.101474] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 08/24/2023] [Indexed: 09/09/2023]
Abstract
Stroke represents a major burden in patients with type 2 diabetes, yet this cerebrovascular complication has been less carefully investigated than the risk of cardiovascular mortality, heart failure and renal disease. Some data suggested that glucagon-like peptide-1 receptor agonists (GLP-1RAs) exert a better protection against stroke than sodium-glucose cotransporter 2 inhibitors (SGLT2is). However, this conclusion was derived from indirect comparisons in absence of any head-to-head randomised controlled trial (RCT). The present comprehensive review compares the effects of SGLT2is versus GLP-1RAs on nonfatal and fatal/nonfatal strokes in network meta-analyses of RCTs (mostly cardiovascular outcome trials) versus placebo, on the one hand, and in real-life observational cohort studies, on the other hand. Whereas network meta-analyses of placebo-controlled RCTs confirm a slight but significant (in 11 out of 13 meta-analyses) higher incidence of stroke in patients treated with SGLT2is compared with those treated with GLP-1RAs, a large majority of retrospective observational cohort studies (19 out of 21) failed to find any significant difference in the risk of stroke between the two pharmacological classes. Available, yet limited, findings suggest that SGLT2is may be more efficacious against haemorrhagic than ischaemic strokes, in patients at risk for atrial fibrillation and in patients with chronic kidney disease.

The current role of SGLT2 inhibitors in type 2 diabetes and beyond: a narrative review. Expert Rev Endocrinol Metab 2023; 18:271-282.

Abstract
INTRODUCTION Sodium-glucose cotransporter 2 inhibitors (SGLT2is, gliflozins), the most recent oral antihyperglycaemic agents, provide a cardiorenal protection, an effect independent of their glucose-lowering potency. AREAS COVERED The antihyperglycaemic potency of SGLT2is was compared with that of dipeptidyl peptidase-4 inhibitors and glucagon-like peptide-1 receptor agonists, especially when added to metformin monotherapy. Main results of cardiovascular/renal outcome trials with SGLT2is were summarized in different populations: patients with type 2 diabetes mellitus (T2DM) with or without established cardiovascular disease, patients (with or without T2DM) with heart failure (with reduced or preserved left ventricular ejection fraction) and in patients (with or without T2DM) with chronic kidney disease (CKD, including stage 4). Original papers and meta-analyses of these different trials have consistently reported a reduction in hospitalization for heart failure (alone or combined with cardiovascular mortality) and a reduced progression of CKD, with an overall good safety profile. EXPERT OPINION Global use of SGLT2is has increased over time but remains suboptimal despite clinically relevant cardiovascular and renal protection, particularly in patients most likely to benefit. SGLT2is has proven both positive benefit-risk balance and cost-effectiveness in at risk patients. New prospects are expected in other complications, i.e. metabolic-associated fatty liver disease and neurodegenerative disorders.

Abstract
The management of type 2 diabetes (T2D) after a gastric bypass or a sleeve gastrectomy requires some cautions depending on the timing after the surgical procedure and the patient evolution. Even before the intervention, gliflozins should be interrupted to avoid euglycemic diabetic ketoacidosis while sulphonylureas should be stopped and insulin doses should be reduced (with caution) to limit the risk of hypoglycemia. If a remission of T2D occurs, the maintenance of metformin or of a glucagon-like peptide-1 receptor agonist should be considered with the main objective to prolong the remission. Finally, if T2D remains or if a relapse occurs, the management of hyperglycemia should a priori follow the same rules as those used for patients with T2D who are not treated with bariatric/metabolic surgery.

Abstract
Metabolic-Associated Fatty Liver Disease (MAFLD) is a prevalent metabolic complication among patients with obesity and type 2 diabetes, associated with bad prognosis. Classical antidiabetics have little effects on this complication, except pioglitazone that exerts a positive impact but with uncertain safety. Gliptins are almost neutral, whereas glucagon-like peptide-1 receptor agonists showed benefits, the most potent ones being those associated with a greater weight loss such as liraglutide or semaglutide. Gliflozins also reduce hepatic fat content and liver enzymes used as biomarkers of steatosis. However, histological data remain scarce, especially those focusing on inflammation and fibrosis, and direct comparative data between available therapies are still lacking.

Abstract
INTRODUCTION Type 2 diabetes and liver disease, mainly metabolic-associated fatty liver disease (MAFLD) and more rarely cirrhosis, coexist in many patients. This duality has direct implications for the physician when choosing glucose-lowering agents, with classical concerns but also recent new hopes. AREAS COVERED This updated comprehensive review will consider the pharmacokinetics, the tolerance/safety profile, the benefit/risk balance in cirrhosis, the effects on MAFLD and the risk of hepatocellular carcinoma of old and new glucose-lowering compounds in patients with liver disease, with a special focus on glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter 2 inhibitors. EXPERT OPINION We are currently facing a new paradigm in the management of patients with diabetes and liver disease. From previous reluctance when using antidiabetic agents (except insulin) in diabetic patients with hepatic impairment because of safety concerns, the commercialization of novel glucose-lowering agents has changed the scene. These agents, which have a good safety profile, are associated with weight loss and pleiotropic effects. They have proven their efficacy in improving MAFLD. However, more specific studies are still needed to prove their efficacy in preventing the progression to fibrosis/cirrhosis and confirm this new opportunity for the management of patients with diabetes and liver disease.

Abstract
Bariatric/metabolic surgery and sodium-glucose cotransporter 2 inhibitors (SGLT2is) are becoming increasingly popular for the management of overweight/obese patients with type 2 diabetes mellitus (T2DM). Consequently, the chance that a patient undergoing bariatric/metabolic surgery is also treated with an SGLT2i would be rather common in clinical practice. Both risks and benefits have been reported. On the one hand, several cases of euglycemic diabetic ketoacidosis have been reported within the few days/weeks after bariatric/metabolic surgery. The causes are diverse but a drastic reduction in caloric (carbohydrate) intake most probably plays a crucial role. Thus, SGLT2is should be stopped a few days (and even more if a pre-operative restricted diet is prescribed to reduce liver volume) before the intervention and reintroduced only when the caloric (carbohydrate) intake is sufficient. On the other hand, SGLT2is may exert a favorable effect to reduce the risk of postprandial hypoglycemia, a complication reported among patients who have been treated with bariatric/metabolic surgery. An increased hepatic glucose production and a reduced production of interleukin-1β have been proposed as possible underlying mechanisms for this protective effect. Finally, whether SGLT2is could prolong diabetes remission following surgery and improve the prognosis of patients with T2DM who benefit from bariatric/metabolic surgery remains to be investigated.

Abstract
INTRODUCTION Atherosclerotic cardiovascular disease (ASCVD) and heart failure (HF) are two major complications of type 2 diabetes (T2DM). Cardiovascular protection is a key objective, yet not fully reached in clinical practice. AREAS COVERED Both glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) have proven their efficacy in reducing major cardiovascular events in high-risk patients with T2DM and SGLT2is in reducing hospitalization for HF in placebo-controlled randomized trials. However, real-life studies worldwide revealed that only a minority of patients with T2DM receive either a GLP-1RA or an SGLT2i and surprisingly even less patients with established ASCVD or HF are treated with these cardioprotective antihyperglycemic agents. EXPERT OPINION Bridging the gap between evidence-based cardiovascular protection with GLP-1RAs and SGLT2is and their underuse in daily clinical practice in patients with T2DM at high risk is crucial from a public health viewpoint. However, the task appears hazardous and the goal not attained considering the current failure. Education of specialists/primary care physicians and patients is critical. Multifaceted and coordinated interventions involving all actors (physicians, patients and broadly health-care system) must be implemented to stimulate the adoption of these cardioprotective antihyperglycemic medications as part of routine cardiovascular care among patients with T2DM.

Abstract
Psychotropic drugs may be associated with metabolic disorders, often but not only triggered by weight gain. Disorders include dysglycemia and diabetes, atherogenic dyslipidemia and metabolic syndrome. Overall, metabolic risk is lower with antidepressants than with antipsychotics. Among antidepressants, metabolic disorders may occur with both selective serotonin reuptake inhibitors and tricyclics, but with some between-molecule differences in each pharmacological family. Among antipsychotics, the risk is higher with second-generation (atypical) than first-generation agents. Higher risk was reported with clozapine and olanzapine, and lower risk with risperidone and aripiprazole. Weight gain is associated with increased insulin resistance, but impaired insulin secretion was also reported with clozapine and olanzapine. Metabolic disorders may be attenuated by the medication withdrawal and replacement by another safer drug. Besides deleterious effects of medications, the psychiatric population is also exposed to bad lifestyle habits (unhealthy diet and sedentary life), which also increase the risk of metabolic disorder. Management should first reinforce lifestyle measures. If this proves insufficient, specific drugs may be considered to tackle the metabolic disorder on a strategy similar to that applied in the general population.

Abstract
Type 2 diabetes mellitus (T2DM) is a highly prevalent health condition in the aging population. Older adults with T2DM have higher risks of cardiovascular disease, heart failure (long underestimated) and premature death than those without diabetes. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) have proven their ability to improve cardiovascular prognosis and reduce the risk of hospitalization for heart failure (hHF). However, several adverse events have been reported, whose incidence and severity might be increased in the elderly population. The aims of this comprehensive review were to analyze the benefit-risk ratio of SGLT2i therapy in older patients with T2DM by collecting data from (i) large prospective placebo-controlled cardiovascular outcome trials (including those dedicated to heart failure), using both original publications and dedicated post-hoc analyses across different age groups and (ii) observational cohort studies, describing the effects of SGLT2is versus other glucose-lowering agents on cardiovascular outcomes and hHF in elderly patients or these effects in different age groups. Overall, consistent results showed a similar relative risk reduction in cardiovascular mortality and hHF with SGLT2is independently of age. The absolute risk reduction may be greater in elderly because of a higher background risk in older versus younger patients. Similarly, the safety profile of SGLT2is appeared comparable in older versus younger patients. In conclusion, the benefit/risk balance favors the use of SGLT2is in older patients at risk of cardiovascular disease and/or heart failure. Caution may be required in very old frail patients, especially those exposed to an increased risk of volume depletion.

Abstract
The pharmacotherapy of type 2 diabetes mellitus (T2DM) has markedly evolved in the last two decades. Classical antidiabetic agents (sulphonylureas, metformin, insulin) are now in competition with new glucose-lowering medications. Alpha-glucosidase inhibitors and thiazolidinediones (glitazones) were not able to replace older agents, because of insufficient efficacy and/or poor tolerability/safety. In contrast, incretin-based therapies, both dipeptidyl peptidase-4 inhibitors (DPP-4is or gliptins, oral agents) and glucagon-like peptide-1 receptor agonists (GLP-1RAs, subcutaneous injections) are a major breakthrough in the management of T2DM. Because they are not associated with hypoglycaemia and weight gain, DPP-4is tend to replace sulphonylureas as add-on to metformin while GLP-1RAs tend to replace basal insulin therapy after failure of oral therapies. Furthermore, placebo-controlled cardiovascular outcome trials demonstrated neutrality for DPP-4is, but cardiovascular protection for GLP-1RAs in patients with T2DM at high cardiovascular risk. More recently sodium-glucose cotransporter 2 inhibitors (SGLT2is or gliflozins, oral agents) also showed cardiovascular protection, especially a reduction in hospitalization for heart failure, as well as a renal protection in patients with and without T2DM, at high cardiovascular risk, with established heart failure and/or with chronic kidney disease. Thus, GLP-1RAs and SGLT2is are now considered as preferred drugs in T2DM patients with or at high risk of atherosclerotic cardiovascular disease whereas SGLT2is are more specifically recommended in patients with or at risk of heart failure and renal (albuminuric) disease. The management of T2DM is moving from a glucocentric approach to a broader strategy focusing on all risk factors, including overweight/obesity, and to an organ-disease targeted personalized approach.

Abstract
2022 corresponds to the 100th anniversary of the discovery of glucagon. This TimeCapsule aims to recall the main steps leading to the discovery, characterisation, and clinical importance of the so-called second pancreatic hormone. We describe the early historical findings in basic research (ie, discovery, purification, structure, α-cell origin, radioimmunoassay, glucagon gene [GCG], and glucagon receptor [GLR]), in which three future Nobel Prize laureates were actively involved. Considered as an anti-insulin hormone, glucagon was rapidly used to treat insulin-induced hypoglycaemic coma episodes in people with type 1 diabetes. A key step in the story of glucagon was the discovery of its role and the role of α cells in the physiology and pathophysiology (ie, paracrinopathy) of type 2 diabetes. This concept led to the design of different strategies targeting glucagon, among which GLP-1 receptor (GLP1R) agonists were a major breakthrough, and combination of inhibition of glucagon secretion with stimulation of insulin secretion (both in a glucose-dependent manner). Taking advantage of the glucagon-induced increase in energy metabolism, biased coagonists were developed. Besides the GLP-1 receptor, these coagonists also target the glucagon receptor to further promote weight loss. Thus, the 100-year story of glucagon has most probably not come to an end.

Abstract
Glucagon-like peptide-1 (GLP-1) receptor agonists currently occupy a privileged place in the management of type-2 diabetes (T2D). Dual glucose-dependent insulinotropic polypeptides (GIP/GLP-1) have been recently developed. Tirzepatide is the most advanced unimolecular dual GIP/GLP-1 receptor agonist to be used as once weekly subcutaneous injection in T2D and recently received approval by the European Medicines Agency. Because of the complementarity of action of the two incretins, tirzepatide showed better dose-dependent (5, 10 and 15mg) efficacy (greater reduction in HbA1c and body weight) than placebo, basal insulin or two GLP-1 analogues (dulaglutide and semaglutide) in the SURPASS program. Its cardiovascular protective effect is currently being assessed versus dulaglutide in the SURPASS-CVOT study. Finally, studies for the treatment of obesity (SURMOUNT program) and metabolic-associated fatty liver disease (MAFLD) are also ongoing. Gastrointestinal tolerance of tirzepatide appears comparable to that of GLP-1 analogues, except for higher incidence of diarrhea. Other original molecules have been built, including triple GIP/GLP-1/glucagon receptor agonists. The risk/benefit ratio will decide whether dual (or triple) receptor agonists should replace pure GLP-1 receptor agonists for the management of T2D in the near future, with a significant role in the pharmacotherapy of obesity.

Abstract
The inhibition of the renin-angiotensin system represents the first preventive treatment of the chronic kidney disease (CKD), especially in presence of albuminuria. Recently, sodium-glucose cotransporter type 2 inhibitors (SGLT2i, gliflozins) demonstrated a nephroprotective effect, first in patients with type 2 diabetes at cardiovascular risk, then in diabetic patients with CKD assessed by a reduction of the glomerular filtration rate (GFR) and albuminuria (CREDENCE with canagliflozin), and finally in patients with CKD and albuminuria, with or without diabetes (DAPA-CKD with dapagliflozin). EMPA-KIDNEY study compared the effects of empagliflozin 10 mg/day versus placebo in patients with CKD, with or without diabetes. In comparison with the two previous renal studies, this clinical trial randomised patients with a lower GFR (78 % of patients with GFR inferior to 45 mL/min/1.73 m²) and a lower level of albuminuria (20 % of patients without pathological albuminuria). EMPA-KIDNEY demonstrated a reduction by 28 % (p inferior to 0.001) of the primary composite outcome (progression of CKD or cardiovascular death) and of several renal endpoints, including the shift to terminal CKD (-33 %), independently of the presence of diabetes, and with a tolerance profile comparable to what is already known. EMPA-KIDNEY results reinforce the use of SGLT2is, in general, and of empagliflozin, in particular, in a broader population with CKD and, thus, the indication of this pharmacological class in nephrology in combination with inhibitors of the renin-angiotensin system.

Abstract
PCSK9 (Proprotein Convertase Subtilisin/Kexin type 9) inhibition has proven its interest to potentiate the cholesterol-lowering effects of statins. Indeed, this protein contributes to the intracellular degradation of LDL cholesterol receptors and thereby reduces their recycling and expression at the hepatocyte membrane. PCSK9 inhibition allows a major and sustained reduction of LDL cholesterol (LDL-c) in patients with familial hypercholesterolaemia or with established cardiovascular disease. Two monoclonal antibodies that inhibit the effect of PCSK9 are currently commercialized, alirocumab and evolocumab. Another approach consists in the inhibition of PCSK9 synthesis. Inclisiran is a novel small interfering RNA-based therapy (anti-sense). By binding to the messenger RNA (mRNA) precursor of PCSK9, inclisiran inhibits the PCSK9 gene expression, resulting in increased hepatocyte recycling and membrane expression of LDL receptors and decreased levels of LDL-c. This article summarizes the mode of action, pharmacokinetics, efficacy, safety profile, indications and reimbursement conditions of inclisiran. This novel cholesterol-lowering drug is indicated as add-on therapy in adults with atherosclerotic cardiovascular disease or with heterozygous familial hypercholesterolaemia in whom LDL-c level is ? 100 mg/dl and does not reach target LDL-c levels despite statin and ezetimibe or without statin or ezetimibe in case of intolerance or contra-indication for one of these medications.

Abstract
Sodium-glucose cotransporter type 2 inhibitors (SGLT2i or gliflozins) improve the prognosis of patients with heart failure, independently of the presence of diabetes. They are now recommended for the treatment of heart failure in international guidelines. The addition of a gliflozin driven by such a cardiological indication may require some adjustment of the antidiabetic therapy. The aim of this concise article is to discuss the potential risk of hypoglycaemia, highly deleterious in fragile patients at risk, following the prescription of a gliflozin in patients with heart failure. Different clinical situations will be considered, both in nondiabetic patients and in patients with type 2 diabetes already treated with a variety of antihyperglycaemic agents, metformin, sulphonylureas, gliptins, GLP-1 receptor agonists and insulin.

Abstract
Streptococcus pneumoniae infections cause bacteremic and non-bacteremic community-acquired pneumonia and invasive pneumococcal diseases (IPD) such as bacteremia, sepsis and acute meningitis. They are potentially lethal. Although polysaccharide vaccines (PPV23, Pneumovax 23®) have already provided protection in at-risk individuals, they have been imperfect, mainly because the development of anti-polysaccharide antibodies occurs without the help of T cells. The introduction of immunogenic protein conjugate vaccines (ICVs) has overcome this problem and provided better and longer lasting protection. The first available vaccine of this type for adults was Prevenar 13®, targeting 13 polysaccharides of S. pneumoniae (PCV13). A new vaccine, Apexxnar®, targeting 20 polysaccharides (PCV20), the 13 of Prevenar 13®, to which 7 other serotypes considered to be equally responsible for invasive infections have been added, has recently been launched. Clinical studies have demonstrated a good immunogenic response against all 20 serotypes in adult patients who are either vaccine-naive or previously vaccinated with PPV23 and/or PCV13. Furthermore, the tolerance of the PCV20 vaccine was found to be comparable to that of Prevenar 13®. Vaccination with PCV20 involves a single injection. The Belgian Superior Health Council has recently reiterated the importance of vaccinating at-risk individuals against S. pneumoniae (a vaccination that is still under-performed). It now recommends vaccination with PCV20 (Apexxnar®) as the preferred primary vaccination regimen in high-risk adults with co-morbidities or in good health aged between 65 and 85 years.

Abstract
Tirzepatide is a unimolecular dual agonist of both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, which is developed as once-weekly injection for the treatment of type 2 diabetes. Because of the complementarity of action of the two incretins, tirzepatide showed, in a dose-dependent manner (5, 10 and 15 mg), a better efficacy (greater reduction in HbA1c and body weight) compared with placebo, basal insulin and two GLP-1 analogues (dulaglutide and semaglutide) in the SURPASS program. Its cardiovascular protection (versus dulaglutide) is currently tested in SURPASS-CVOT. Finally, studies for the treatment of obesity and metabolic associated fatty liver disease are also ongoing. Gastrointestinal tolerance of tirzepatide appears comparable to that of GLP-1 analogues, except more diarrhoea.

Abstract
Gliflozins (sodium-glucose cotransporter type 2 inhibitors or SGLT2is) reduced hospitalisations for heart failure in all large prospective cardiovascular outcome trials performed in patients with type 2 diabetes at risk of cardiovascular disease. This protective effect was confirmed in two dedicated trials that specifically targeted patients with heart failure and reduced left ventricular ejection fraction (DAPA-HF with dapagliflozin and EMPEROR-reduced with empagliflozin) and in two trials in patients with preserved left ventricular ejection fraction (EMPEROR-preserved with empagliflozin and DELIVER with dapagliflozin), independently of the presence of diabetes. These favourable results contribute to give a privileged position to SGLT2is in recent international guidelines produced by diabetologists and cardiologists.

Abstract
INTRODUCTION : Heart failure (HF) is becoming a huge public health burden. New diabetes drugs for type 2 diabetes (T2D), sodium-glucose cotransporter type 2 inhibitors (SGLT2is), reduce the rate of hospitalization for HF in placebo-controlled trials. AREAS COVERED : Pharmacokinetics of dapagliflozin and empagliflozin (in presence of renal impairment and hepatic dysfunction, two comorbidities frequently associated with HF) and pharmacodynamic studies in patients with HF. Main HF outcomes in T2D patients with cardiovascular risk and in patients with reduced (HFrEF) or preserved (HFpEF) ejection fraction, with or without T2D, from DAPA-HF, EMPEROR-Reduced and EMPEROR-Preserved original findings and post hoc analyses. EXPERT OPINION : No clinically relevant changes are expected concerning SGLT2i pharmacokinetics in patients with HF while pharmacodynamic studies reported improvements in myocardium/vascular parameters, biomarkers and functional status. All SGLT2is showed a remarkable reduction in hospitalization for HF in patients with T2D and high cardiovascular risk. Furthermore, both dapagliflozin and empagliflozin improved the prognosis of patients with HFrEF, independently of the presence of T2D. Similar results were reported with empagliflozin in patients with HFpEF, to be confirmed with dapagliflozin in an ongoing trial (DELIVER). Thus, SGLT2is offer a new opportunity for the prevention and management of HF in patients with or without T2D.

Abstract
Anti-inflammatory medications are known since a long time and still remain among the most used drugs in clinical practice. They belong to a variety of pharmacological classes and act via very different biochemical mechanisms. Nonsteroid anti-inflammatory drugs, which are derived from acetylsalicylic acid, and cortisone with its multiple derivative molecules (glucocorticoids) remain the background therapy of diseases associated with inflammation, either acute or chronic. Some old molecules, known to exert an anti-inflammatory activity, still have specific indications, colchicine and methotrexate as examples. However, the greatest innovation of the last two decades results from the launch of biological therapies, starting with the use of anti-TNF? agents to move towards monoclonal antibodies targeting various pro-inflammatory interleukins (IL-1, IL-6, IL-5, IL-17, IL-23, …). Finally, small molecules acting as JANUS kinase inhibitors or tyrosine kinase 2 inhibitors open new alternatives in severe diseases that are resistant to other anti-inflammatory drugs. The interest for anti-inflammatory medications has been reinforced since the COVID-19 outbreak.

Abstract
Diseases related to fatty liver, independently of alcohol consumption («non-alcoholic fatty liver disease» or NAFLD), are increasing because of the epidemics of obesity and type 2 diabetes. These disorders reflect a continuum that comprises isolated steatosis, steatohepatitis (NASH) and fibrosis, with, at the end, an increased risk of cirrhosis and hepatocarcinoma. It has been recently proposed to replace the term NAFLD by MAFLD, i.e. «Metabolic (dysfunction) Associated Fatty Liver Disease», which better reflects the pathogenesis of the disease. Inflammation plays a crucial role in the aggravation of the disorder and profoundly influences the prognostic evolution. This article illustrates the natural history of this underestimated metabolic disorder, recall the diagnostic criteria used in clinical practice, emphasizes the deleterious role of inflammation and discusses some therapeutic perspectives.

Abstract
The relationships between inflammation and cancer are known since the original work by Virchow in the 19th century and have been largely confirmed after-wards. An interesting question is what might be the primum movens. Numerous clinical observations have shown that a chronic inflammatory state, as that observed with some infections, toxic agents or dysimmune diseases, may be associated with the development of cancer later on. Besides, cancer is generally accompanied by an inflammatory microenvironment, with numerous cellular and humoral components, which promotes both tumorigenesis and the invasivity of the tumour. This article aims at defining the pathophysiology of this association, with a description of underlying mechanisms and mediators, and at determining possible therapeutic implications.

Abstract
Drug-induced diabetes mellitus is a growing problem in clinical practice. New, potent medications contribute to this problem in a population already at high risk of developing glucose disturbances because of poor lifestyle habits and high prevalence of being overweight/obese. The present review focuses on four important pharmacological classes: glucocorticoids; antipsychotics, especially second generation; antiretroviral therapies, which revolutionised the management of individuals with HIV; and immune checkpoint inhibitors, recently used for the immunotherapy of cancer. For each class, the prevalence of drug-induced diabetes will be evaluated, the most common clinical presentations will be described, the underlying mechanisms leading to hyperglycaemia will be briefly analysed, and some recommendations for appropriate monitoring and management will be proposed.

Abstract
Since their launch, sodium-glucose cotransporter type 2 inhibitors (SGLT2is) were suspected to be associated with various adverse events. They contributed to delay, as in France, or to restrict the use of this new pharmacological class in clinical practice, despite remarkable results reported in large cardiovascular or renal clinical trials. This article is devoted to three major adverse events that were imputed to SGLT2is : lower-limb extremity amputations, euglycaemic ketoacidosis and acute kidney injuries. In contrast to pharmacovigilance reports that raised suspicion, analysis of all data from the literature, either placebo-controlled trials or retrospective observational cohort studies, led to rather reassuring conclusions. The incidence of amputations does not appear to be increased while cases of acute kidney injury are reduced instead of increased as suspected earlier. Ketoacidosis events are almost doubled with SGLT2is versus comparators, yet their incidence remains extremely low among patients with type 2 diabetes. Of note, this potentially severe complication contributes to the denial of marketing authorization and reimbursement of SGLT2is in the population with type 1 diabetes.

Abstract
Most physicians do not know, or do not remember, the name of phlorizin. Hence this molecule has a major historical importance because it was the precursor of gliflozins, a new class of oral antidiabetic drugs with recent therapeutic perspectives beyond diabetes. This article recalls the history of phlorizin: its discovery in the 19th century by De Koninck and Stas, the demonstration of its ability to induce glucosuria and reduce hyperglycaemia by von Mering, its use to demonstrate the concept of glucose toxicity by the team of DeFronzo and finally the development of selective (phlorizin being not selective) sodium-glucose cotransporter type 2 inhibitors (gliflozins) which block glucose reabsorption in renal tubules. Gliflozins have increasing therapeutic indications, not only in type 2 diabetes, but also in cardiology and nephrology among non-diabetic people with heart failure or renal insufficiency.

Abstract
Patients at high or very high cardiovascular risk should have a LDL cholesterol level as low as possible, a target that may be difficult to be reached with statin monotherapy, especially when this treatment is not well tolerated. It is generally recommended to use pharmacological combinations to reach more and more strict objectives. Bempedoic acid is a new oral cholesterol-lowering medication that reduces hepatic cholesterol synthesis by inhibiting the enzyme adenosine triphosphate (ATP)-citrate lyase enzyme. Because this medication is a prodrug that is selectively activated in the liver, it is deprived of any muscular adverse effect. This article summarizes the mode of action, pharmacokinetics, efficacy, safety profile, indications and reimbursement conditions of bempedoic acid. This novel cholesterol-lowering drug is indicated in combination with statins (with or without ezetimibe) in patients who do not attain LDL goals despite administration of a statin at the maximum tolerated dose or in case of statin intolerance.

Abstract
INTRODUCTION Sodium-glucose co-transporter type 2 inhibitors (SGLT2is) were developed as glucose-lowering agents for the management of type 2 diabetes (T2D). Unexpectedly, they showed a significant reduction in hospitalization for heart failure and hard renal outcomes in patients with and without T2D. Underlying mechanisms remain a matter of debate. AREAS COVERED We summarize the protective renal effects of SGLT2is in patients with cardiovascular disease, chronic kidney disease (CKD, especially with albuminuria) or heart failure; a description of the safety of SGLT2is, with a special focus on the risk/benefit balance in people with stage 3 CKD; a comprehensive discussion of mechanisms that could explain nephro-protection; a reappraisal of the positioning of SGLT2is in recent international guidelines. EXPERT OPINION Several mechanisms could contribute to improved renal prognosis with SGLT2is, among which a reduction in intraglomerular pressure by restoring the tubuloglomerular feedback, a diuretic effect that contributes to lower albuminuria and renal decongestion, especially if fluid overload is present, a reduction in renal oxygen consumption, an improvement of heart failure status with less cardiorenal syndrome and a lower risk of acute renal injury. All these effects may be mutually not exclusive, and their respective contribution may differ according to patient characteristics.

Abstract
Both renin-angiotensin-aldosterone system inhibitors (RAASi) and sodium-glucose cotransporter type 2 inhibitors (SGLT2i, gliflozins) reduce the risk of heart failure and of progressing towards end-stage renal disease, especially in patients with type 2 diabetes (T2D). Positive results reported in patients with T2D have been confirmed in people without diabetes. These two pharmacological classes now occupy a privileged place in international guidelines, in diabetology, cardiology and nephrology. The present article describes similarities and differences between these two types of medications. It emphasizes the importance of combining both approaches in order to optimize the cardiovascular and renal prognosis, while maintaining a good safety profile.

Abstract
Renin-angiotensin-aldosterone system (RAAS) blockers and sodium-glucose cotransporter type 2 inhibitors (SGLT2is) are two pharmacological classes that proved a remarkable nephroprotective effect, yet a risk of acute kidney injury (AKI) was also pointed out. In 2016, the US Food and Drug Administration recommended caution with the concomitant use of these medications. While the literature devoted to RAAS blockers remained surprisingly limited, numerous articles were published in recent years with SGLT2is. Safety analyses of large prospective cardiorenal trials showed a reduced rather than an increased number of AKI events in patients with type 2 diabetes treated with SGLT2is compared with those treated with placebo, despite the fact that a majority of patients received RAAS blockers at baseline. Interestingly, retrospective observational studies confirmed these reassuring findings in real-life conditions in more heterogeneous and possibly more frailty populations also commonly treated with RAAS blockers by showing a reduced risk of AKI with SGLT2is compared with other glucose-lowering drugs. Currently, there are no evidence of an increased risk of AKI with RAAS blocker-SGLT2i combinations in absence of haemodynamic instability. Several underlying mechanisms could explain a decreased rather than an increased risk of AKI with SGLT2is, including in patients treated with RAAS blockers.

Abstract
Chronic kidney disease is a prevalent complication of type 2 diabetes mellitus (T2DM). Sodium-glucose cotransporter type 2 inhibitors (SGLT2is) have a unique mode of action targeting the kidney. As their glucose-lowering potency declines with the reduction in estimated glomerular filtration rate, their clinical use in patients with T2DM with chronic kidney disease has been submitted to restriction. However, recent observations demonstrated that SGLT2is reduce the progression of renal impairment in patients with mild-to-moderate chronic kidney disease, with or without albuminuria. Furthermore, SGLT2is reduce the incidence of cardiovascular events in patients with T2DM at high cardiovascular risk, independently of baseline estimated glomerular filtration rate. Thus, recent guidelines recommend the prescription of SGLT2is in patients with T2DM with mild-to-moderate chronic kidney disease defined by an estimated glomerular filtration rate between ≥ 30 and < 90 mL/min/1.73 m2 and/or albuminuria. The present comprehensive review describes the pharmacokinetic/pharmacodynamic properties of SGLT2is commercialised worldwide and in Japan in patients with T2DM with mild, moderate and severe chronic kidney disease. Drug exposure increases when the estimated glomerular filtration rate declines but without a clear-cut relationship with the severity of chronic kidney disease and in a rather moderate amplitude that most often does not require a dose reduction in the presence of mild-to-moderate chronic kidney disease. The urinary glucose excretion steadily declines with the reduction in estimated glomerular filtration rate. This may explain a lower effect on glucose control, yet the positive effects on body weight and blood pressure still remain. The efficacy and safety of these SGLT2is are analysed among patients with stages 3a and 3b chronic kidney disease in placebo-controlled randomised clinical trials, with almost similar results in Asian and non-Asian individuals with T2DM. In summary, there is no reason not to prescribe SGLT2is in patients with T2DM with mild-to-moderate chronic kidney disease, especially if the aim is to benefit from cardiovascular and/or renal protection.

Abstract
Dipeptidyl peptidase-4 inhibitors (DPP-4is) and sodium-glucose cotransporter type 2 inhibitors (SGLT2is) offer new options for the oral management of type 2 diabetes mellitus (T2DM), with the advantage in the elderly population to be devoid of a high risk of hypoglycaemia. SGLT2is have also shown benefits regarding cardiovascular (heart failure) and renal protection, including in patients with T2DM aged ≥ 65 years while DPP-4is have only proved cardiovascular and renal safety without superiority compared with placebo. The glucose-lowering efficacy of the two pharmacological classes is almost similar including in older patients with T2DM. However, the tolerance and safety profile may be highly different and overall more favourable with DPP-4is than with SGLT2is. Some adverse events have been reported with SGLT2is which may be more prevalent or severe in older patients than in younger patients. The present comprehensive review focuses on the benefit/risk balance in the elderly population with T2DM by comparing the profile of DPP-4is and SGLT2is regarding the following potential issues: metabolic disorders (hypoglycaemia and diabetic ketoacidosis); cardiac and vascular issues (atheromatous cardiovascular disease, heart failure, volume reduction hypotension, and lower limb amputations); renal endpoints including acute renal injury; risk of infections; digestive disorders; bone and skin adverse events; and cancer risk. Both DPP-4is and SGLT2is have their own advantages and disadvantages. Personalised treatment is recommended based upon the efficacy/safety profile of each drug class and individual patient characteristics that may be markedly different among the heterogeneous population of older individuals with T2DM.

Abstract
The relationships between sodium-glucose cotransporter type 2 inhibitors (SGLT2is) and kidney are complex: reduction of the glucose-lowering effect with the decline of glomerular filtration rate (GFR), biphasic effects on GFR along with treatment duration, low risk of acute kidney injury, rapid reduction of albuminuria, and, most importantly in clinical practice, a remarkable nephroprotection, with a decrease of the risk of end-stage renal disease or death from renal cause. This article describes the renal outcomes in the main clinical trials and analyses the impact of treatment with SGLT2is on renal prognosis according to different patient baseline characteristics. A nephroprotection is observed whatever the severity (even if GFR < 45 ml/min/1,73 m²) and type (with or without albuminuria, with or without diabetes) of renal disease.

[Potentiation of weight reduction with GLP-1 receptor agonists]. REVUE MEDICALE SUISSE 2021; 17:1405-1410. [PMID: 34431633] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/13/2023]
Abstract
Glucagon-like peptide-1 receptor agonists are the antidiabetic agents that are associated with the greatest weight loss beyond a marked reduction in glycated haemoglobin. Weight loss results from a reduction in appetite through a predominant central effect combined with a peripheral effect. Liraglutide and semaglutide are developed for the treatment of obesity, independently of type 2 diabetes. Three approaches may be considered to potentiate weight loss: an increase of the drug dosage because of the demonstration of a dose-response, an add-on therapy with a sodium-glucose cotransporter type 2 inhibitor as this agent exerts a complementary action through urinary calorie loss (glucosuria) or a combination of the effects of two incretin hormones (GLP-1 and GIP), as the potent dual agonist tirzepatide currently in development.

Abstract
Environment contains numerous potentially toxic substances among which certain have demonstrated to be carcinogenic. They can reach the human organism mainly through the repiratory or digestive routes. Even if it is not always easy to demonstrate a causal relationship in observational studies whose interpretation is limited by numerous confounding factors, some compounds from the environment are clearly associated with a higher risk of cancers. The present article describes the effects of both outdoor and indoor air pollution, pesticides, some endocrine disruptors and radiations. The identification of environmental factors associated with a higher risk of cancer allows implement eradication strategies and thereby efficacious prevention.

Abstract
INTRODUCTION An increasing number of older patients has type 2 diabetes treated with different oral antidiabetic agents whose safety may raise concern considering some particularities of a heterogeneous elderly population. AREAS COVERED This article discusses some characteristics of older patients that could increase the risk of adverse events, with a focus on hypoglycemia. It describes the most frequent and/or severe complications reported in the elderly in both randomized controlled trials and observational studies with metformin, sulfonylureas, meglitinides, alpha-glucosidase inhibitors, thiazolidinediones, dipeptidyl peptidase-4 inhibitors (gliptins) and sodium-glucose cotransporter type 2 inhibitors (gliflozins). EXPERT OPINION Old patients may present comorbidities (renal impairment, vascular disease, heart failure, risk of dehydration, osteoporosis, cognitive dysfunction) that could increase the risk of severe adverse events. Sulfonylureas (and meglitinides) induce hypoglycemia, which may be associated with falls/fractures and cardiovascular events. Medications lacking hypoglycemia should be preferred. Gliptins appear to have the best tolerance/safety profile whereas gliflozins exert a cardiorenal protection. However, data are lacking in very old or frailty old patients so that caution and appropriate supervision of such patients are required. Taking advantage of a large choice of pharmacotherapies, personalized treatment is recommended based upon both drug safety profiles and old patient individual characteristics.
