Abstract
Cardiovascular disease (CVD) is the most common non-communicable disease occurring globally. Although previous literature has provided useful insights into the important role that diet plays in CVD prevention and treatment, understanding the causal role of diets is a difficult task considering inherent and introduced weaknesses of observational (e.g. not properly addressing confounders and mediators) and experimental research designs (e.g. not appropriate or well designed). In this narrative review, we organised current evidence linking diet, as well as conventional and emerging physiological risk factors, with CVD risk, incidence and mortality in a series of diagrams. The diagrams presented can aid causal inference studies as they provide a visual representation of the types of studies underlying the associations between potential risk markers/factors for CVD. This may facilitate the selection of variables to be considered and the creation of analytical models. Evidence depicted in the diagrams was systematically collected from studies included in the British Nutrition Task Force report on diet and CVD and database searches, including Medline and Embase. Although several markers and disorders linked to conventional and emerging risk factors for CVD were identified, the causal link between many remains unknown. There is a need to address the multifactorial nature of CVD and the complex interplay between conventional and emerging risk factors with natural and built environments, while bringing the life course into the spotlight.

Effects of sodium-glucose co-transporter-2 inhibitors on kidney, cardiovascular, and safety outcomes in patients with advanced chronic kidney disease: a systematic review and meta-analysis of randomized controlled trials. Acta Diabetol 2023; 60:325-335. [PMID: 36316605 DOI: 10.1007/s00592-022-01989-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 09/25/2022] [Indexed: 02/17/2023]
Abstract
AIMS The overall effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors in patients with advanced chronic kidney disease (CKD) (estimated glomerular filtration rate (eGFR), 15-30 ml/min per 1.73 m2) remain unclear, and we thus conducted a systematic review and meta-analysis to evaluate the effects of SGLT2 inhibitors on kidney, cardiovascular (CV), and safety outcomes in patients with advanced CKD. METHODS The Medline, Embase, and Cochrane Library databases were systematically searched for randomized controlled trials (RCTs) published up to March 3, 2022, and reporting effects of SGLT2 inhibitors on kidney, CV, or safety outcomes in patients with advanced CKD. RESULTS From 2675 records, six RCTs with 2167 participants were included in the quantitative analyses. In patients with advanced CKD, SGLT2 inhibitors reduced the risk of the primary kidney outcome (a composite of worsening kidney function, end-stage kidney disease (ESKD), or kidney death) by 23% (RR 0.77, 95% CI 0.61-0.98, p = 0.04, I2 = 0 for the heterogeneity) and slowed the annual decline in eGFR slope, with the difference between SGLT2 inhibitor group and placebo group being 1.24 mL/min/1.73m2 per year (95% CI 0.06-2.42, p = 0.04). SGLT2 inhibitors were also associated with a decreased risk of primary CV outcome (a composite of CV death or hospitalization for heart failure) (HR 0.71, 95% CI 0.53-0.96, p = 0.03, I2 = 0 for the heterogeneity) and with similar risks of adverse events (such as acute kidney injury, fracture, amputation, and urinary tract infection). CONCLUSIONS Among patients with advanced CKD, SGLT2 inhibitors reduced the risks of primary kidney and CV outcomes and attenuated the progressive decrease in eGFR compared with placebo, with no evidence of additional safety concerns. These observed benefits may support continuing the use of SGLT2 inhibitors in patients with advanced CKD before initiating maintenance dialysis or kidney transplantation. Future large-scale RCTs are needed to confirm the robustness of these results.

Abstract
Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) are a relatively new class of medications used for the management of type II diabetes mellitus targeting the kidneys. Within the last decade, several warnings have been issued regarding the development of severe genitourinary infections, including necrotizing fasciitis, or Fournier’s gangrene, in those with pre-existing type II diabetes and concomitant use of this drug class. Objective: The purpose of this review is to highlight and discuss the factors contributing to the development of Fournier’s gangrene, its pathogenesis, and a review of existing literature describing patient outcomes, treatment, and future directions regarding early detection of this complication. Methods: Articles and studies addressing effective treatment adherence and key factors contributing to Fournier’s gangrene with SGLT2 inhibitors were identified by effective keyword searches in PubMed Central, Google Scholar, and Cochrane, as well as the references found within these articles. Results: Using the keywords provided, 55 case reports, review articles, and meta-analysis reports written within the last 20 years were utilized as the source of the data presented in this systematic review article.

Abstract
AIMS Sodium-glucose co-transporter inhibitors (SGLT2i) are emerging as a new treatment for heart failure (HF) after demonstrating favorable clinical outcomes in several randomized controlled trials (RCTs). In this meta-analysis, we assessed the safety of SGLT2i in the trials that prespecified heart failure in their inclusion criteria. MATERIALS AND METHODS We searched the databases for RCTs comparing SGLT2i to placebo in heart failure patients. The primary outcome was the incidence of serious adverse events (SAEs). A sensitivity analysis according to the class of HF was also performed. RESULTS The incidence of SAEs was significantly lower in the SGLT2i group (OR, 0.85; 95% CI, 0.77-0.92; P, 0.0002) and SAEs remained significantly lower after performing the sensitivity analysis (OR, 0.82; 95% CI, 0.75-0.89; P, <0.00001). Genital infections, urinary tract infections (UTIs), and hypotension were significantly higher in the SGLT2i group. CONCLUSIONS SGLT2i remain a safe option for patients with HF with a lower incidence of SAEs. However, since they increase the risk of genital infection, UTIs and hypotension, the risks vs benefits in each patient should be weighed when making a prescribing decision.

Abstract
The upsurge of type 2 diabetes mellitus is a major public health concern in the Middle East and North Africa (MENA) and Africa (AFR) region, with cardiorenal complications (CRCs) being the predominant cause of premature morbidity and mortality. High prevalence of cardiometabolic risk factors, lack of awareness among patients and physicians, deficient infrastructure, and economic constraints lead to a cascade of CRCs at a significantly earlier age in MENA and AFR. In this review, we present consensus recommendations by experts in MENA and AFR, highlighting region-specific challenges and potential solutions for management of CRCs. Health professionals who understand sociocultural barriers can significantly increase patient awareness and encourage health-seeking behavior through simple educational tools. Increasing physician knowledge on early identification of CRCs and personalized treatment based on risk stratification, alongside optimum glycemic control, can mitigate therapeutic inertia. Early diagnosis of high-risk people with regular and systematic monitoring of cardiorenal parameters, development of region-specific care pathways for timely referral to specialists, followed by guideline-recommended care with novel antidiabetics are imperative. Adherence to guideline-recommended care can catalyze utilization of sodium glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists with demonstrated cardiorenal benefits-thus paving the way for overcoming care gaps in a cost-effective manner. Leveraging digital technology like electronic medical records can help generate real-world data and provide insights on voids in adoption of newer antidiabetic medications. A patient-centric approach, collaborative care among physicians from different specialties, alongside involvement of policy makers are key for improving patient outcomes and quality of care in MENA and AFR.

Abstract
Sodium glucose cotransporter 2 (SGLT-2) inhibitors are the latest class of antidiabetic medications. They prevent glucose reabsorption in the proximal convoluted tubule to decrease blood sugar. Several animal studies revealed that SGLT-2 is profoundly involved in the inflammatory response, fibrogenesis, and regulation of numerous intracellular signaling pathways. Likewise, SGLT-2 inhibitors markedly attenuated inflammation and fibrogenesis and improved the function of damaged organ in animal studies, observational studies, and clinical trials. SGLT-2 inhibitors can decrease blood pressure and ameliorate hypertriglyceridemia and obesity. Likewise, they improve the outcome of cardiovascular diseases such as heart failure, arrhythmias, and ischemic heart disease. SGLT-2 inhibitors are associated with lower cardiovascular and all-cause mortality as well. Meanwhile, they protect against nonalcoholic fatty liver disease (NAFLD), chronic kidney disease, acute kidney injury, and improve micro- and macroalbuminuria. SGLT-2 inhibitors can reprogram numerous signaling pathways to improve NAFLD, cardiovascular diseases, and renal diseases. For instance, they enhance lipolysis, ketogenesis, mitochondrial biogenesis, and autophagy while they attenuate the renin-angiotensin-aldosterone system, lipogenesis, endoplasmic reticulum stress, oxidative stress, apoptosis, and fibrogenesis. This review explains the beneficial effects of SGLT-2 inhibitors on NAFLD and cardiovascular and renal diseases and dissects the underlying molecular mechanisms in detail. This narrative review explains the beneficial effects of SGLT-2 inhibitors on NAFLD and cardiovascular and renal diseases using the results of latest observational studies, clinical trials, and meta-analyses. Thereafter, it dissects the underlying molecular mechanisms involved in the clinical effects of SGLT-2 inhibitors on these diseases.

Abstract
ABSTRACT Sodium-glucose cotransporter-2 (SGLT-2) inhibitors showed benefit in patients with heart failure. In this updated meta-analysis, we evaluate the therapeutic efficacy and safety of SGLT-2 inhibitors in patients with heart failure. Different electronic databases were searched to find relevant articles. RevMan 5.4 was used for pooling data using a random/fixed-effects model, complemented by several sensitivity and subgroup analyses. A total of 13 randomized clinical trials including 14,618 patients with heart failure were included in analysis among 6797 studies screened. The overall mortality rate was 12.45% in the SGLT-2 group and 14.67% in the placebo group with 18% lower odds of overall mortality [odds ratio (OR), 0.82; confidence interval (CI), 0.75-0.91] in the SGLT-2 group. Odds of cardiovascular mortality was 18% lower (OR, 0.82; CI, 0.74-0.92) in the SGLT-2 group. The odds of hospitalization for heart failure (HHF) was 38% lower during the study period (OR, 0.62; CI, 0.56-0.68) in the SGLT-2 group. In addition, a benefit was seen for composite outcome HHF or mortality and considering subgrouping based on diabetes status, gender, and age groups. Although genital infection was significantly higher in the SGLT-2 group, the occurrence of severe adverse events, hypoglycemia, urinary tract infection, bone fracture, volume depletion, and other renal events did not differ between the 2 groups. Thus, SGLT-2 inhibitors improved cardiovascular outcomes among patients with heart failure with no significant difference in adverse events. Clinical benefit was comparable in diabetic and nondiabetic individuals, males and females, people in younger and older age groups with underlying heart failure, and HF with reduced ejection fraction.

Abstract
Die „Fetthypothese der koronaren Herzkrankheit“, derzufolge „gesättigte Fettsäuren“ („saturated fatty acids“, SFA) die LDL(„low-density lipoprotein“)-Cholesterin-Konzentration (LDL-C) steigern und folglich das Risiko für kardiovaskuläre Erkrankungen erhöhen, prägte die Ernährungsempfehlungen der letzten 60 Jahre, zunächst in den USA und später auch in Europa. Über die Jahre mehrte sich Evidenz aus Epidemiologie und kontrollierten klinischen Studien, dass der Konsum von SFA per se nicht mit einem erhöhten kardiovaskulären Risiko einhergeht bzw. die Einschränkung des Konsums von SFA keine präventive Wirkung zeigt. Die Fokussierung auf den SFA-Gehalt negiert die biologisch heterogenen und zum Teil biologisch günstigen Wirkungen unterschiedlicher SFA. Zudem wird hierbei außer Acht gelassen, dass SFA in intakten Lebensmitteln in unterschiedliche komplexe Matrizes eingebunden sind, die aus Dutzenden Nährstoffen mit unterschiedlicher Struktur und Begleitstoffen bestehen und damit jeweils unterschiedliche biologische Antworten und metabolische Effekte auslösen. Entsprechend sind solche nährstoffbasierten Empfehlungen prinzipiell wenig zielführend und zudem schlecht umsetzbar. Hinzu kommt, dass LDL‑C kein geeigneter Marker ist, um den Effekt von Lebensstilintervention wie der Ernährung oder aber der körperlichen Aktivität auf das globale kardiovaskuläre Risiko zu beurteilen.

Abstract
Ideal drugs to improve outcomes in type 2 diabetes mellitus (T2DM) are those with antiglycemic efficacy, as well as cardiovascular safety that has to be determined in appropriately designed cardiovascular outcome trials as mandated by regulatory agencies. The more recent antihyperglycemic medications have shown promise with regards to cardiovascular disease (CVD) risk reduction in T2DM patients at a high cardiovascular risk. Sodium glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists are associated with better cardiovascular outcomes and mortality in T2DM patients than are dipeptidylpeptidase-4 inhibitors, leading to the Food and Drug Administration's approval of empagliflozin to reduce mortality, and of liraglutide to reduce CVD risk in high-risk T2DM patients. For heart failure outcomes, sodium glucose cotransporter-2 inhibitors are beneficial, while glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors are neutral. Ongoing and planned randomized controlled trials of these newer drugs should clarify the possibility of class effects and of CVD risk reduction benefits in low-moderate cardiovascular risk patients. While we eagerly await the results on ongoing studies, these medications should be appropriately prescribed in T2DM patients with baseline CVD or those at a high CVD risk after carefully evaluating the elevated risk for adverse events like gastrointestinal disturbances, bladder cancer, genital infections, and amputations. Studies to understand the pleotropic and novel pathophysiological mechanisms demonstrated by the sodium glucose cotransporter-2 inhibitors will shed light on the effects of the modulation of microvascular, inflammatory, and thrombotic milieu for improving the CVD risk in T2DM patients. This is part 2 of the series on noninsulin antihyperglycemic drugs for the treatment of T2DM.

Abstract
Background Controlled studies and observational studies have shown that sodium-glucose cotransporter type 2 inhibitors (SGLT-2i) are beneficial for the survival of patients with heart failure (HF). However, it is unclear whether SGLT-2i can provide benefit in patients with other cardiovascular diseases. Here, we conducted a systematic review and meta-analysis to determine the outcomes of cardiovascular, renal, and safety outcomes of SGLT-2i administration in patients with cardiovascular diseases. Methods We searched PubMed, EMBASE, Cochrane Library, Web of Science databases, and ClinicalTrials.gov databases for randomised controlled trials written in English from inception until November 1, 2020. Two reviewers independently identified randomised controlled trials comparing the effects of SGLT-2i in patients with cardiovascular disease with or without diabetes. Primary outcomes were cardiovascular outcomes and renal outcomes. Secondary outcomes were safety outcomes, including adverse endocrine outcomes and adverse infection outcomes. The effects of SGLT-2i were evaluated using RevMan5.3 software. The Cochrane risk of bias tool was used to assess study quality. Results We identified 10 randomised controlled trials (25,108 patients in the SGLT-2i group and 18,574 patients in the placebo group). Meta-analysis revealed that SGLT-2i treatment significantly reduced all-cause mortality, cardiovascular mortality, and hospitalisation for heart failure (HHF) in patients with cardiovascular disease (all-cause mortality relative risk [RR]: 0.86; 95% confidence interval [CI] 0.81–0.91; P < 0.00001; I2 = 0%; cardiovascular mortality RR: 0.85; 95% CI 0.79–0.92; P < 0.0001; I2 = 26%; HHF RR: 0.69; 95% CI 0.64–0.81; P < 0.00001; I2 = 0%). In patients with HF, mortality and HHF after SGLT-2i treatment for HF with reduced ejection fraction were significantly reduced, whereas HF with preserved ejection fraction did not differ compared with placebo treatment. Moreover, SGLT-2i induced a lower incidence of renal damage and myocardial infarction than the placebo group; however, the risk of infection, amputation, volume depletion, and diabetic ketoacidosis was higher. Conclusions SGLT-2i had significant clinical effects on cardiovascular outcomes and significantly influenced acute kidney injury. The effects of SGLT-2i on cardiovascular disease were independent of diabetic status. Sotagliflozin could have advantages over other SGLT-2i in lowering HHF.

Sodium-glucose cotransporter 2 inhibitor (SGLT2i) use is associated with improved cardiovascular and kidney outcomes. However, the magnitude and potential heterogeneity of effect across patients with varying types of cardiometabolic and kidney disease is unclear. To examine the effect of SGLT2i on cardiovascular and kidney outcomes among patients with type 2 diabetes mellitus (T2DM), and independent of T2DM status, among patients with heart failure (HF), and chronic kidney disease. METHOD Medline, Embase, Cochrane library and scientific conferences were searched from inception till September 24, 2020 for randomized controlled trials comparing cardiovascular and kidney outcomes between SGLT2i and placebo. Random effects hazard ratios (HR) with 95% confidence intervals (CIs) were calculated. RESULTS Eight trials with a combined 59,747 patients were included. In the overall population, SGLT2i reduced the risk of all-cause mortality (HR 0.84; 95% CI [0.78-0.91]), cardiovascular mortality (HR 0.84; 95% CI [0.76-0.93]) hospitalization for HF (HR 0.69; 95% CI [0.64-0.74]), myocardial infarction (HR 0.91; 95% CI [0.84-0.99]), and composite kidney outcome (HR 0.62; 95% CI [0.56-0.70]). There was no significant effect on the risk of stroke (HR 0.98; 95% CI [0.86-1.11]). Results were consistent across subgroups stratified by diabetes and HF status. SGLT2i use was not associated with a greater risk of hypoglycemia (OR 0.92; 95% CI [0.84-1.01]) or amputation (OR 1.25; 95% CI [0.97-1.62]). There were 64 diabetic ketoacidosis events with SGLT2i use and 18 with placebo (OR 2.86; 95% CI [1.39-5.86]). CONCLUSIONS In patients with cardiometabolic and kidney disease, SGLT2i improved cardiovascular and kidney outcomes, regardless of T2DM, HF, and/or CKD status. The magnitude of risk reduction was largest for hospitalization for HF and progression of kidney disease, more modest for mortality and MI and absent for stroke.

Cardiovascular safety and efficacy of metformin-SGLT2i versus metformin-sulfonylureas in type 2 diabetes: systematic review and meta-analysis of randomized controlled trials. Sci Rep 2021; 11:137.

Abstract
Diabetes is a serious threat to global health and among the top 10 causes of death, with nearly half a billion people living with it worldwide. Treating patients with diabetes tend to become more challenging due to the progressive nature of the disease. The role and benefits of combination therapies for the management of type 2 diabetes are well-documented, while the comparative safety and efficacy among the different combination options have not been elucidated. We aimed to systematically synthesize the evidence on the comparative cardiovascular safety and efficacy of combination therapy with metformin-sodium-glucose cotransporter-2 inhibitors versus metformin-sulfonylureas in patients with type 2 diabetes. We searched MEDLINE-PubMed, Embase, Cochrane Library, and ClinicalTrials.gov up to 15 August 2019 without restriction in the year of publication. We included randomized controlled trials of patients with type 2 diabetes who were on metformin-sodium-glucose cotransporter-2 inhibitors or metformin-sulphonylureas combination therapy at least for a year. The primary endpoints were all-cause mortality and serious adverse events, and the secondary endpoints were cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke, hypoglycemia, and changes in glycated hemoglobin A1c (HbA1c), body weight, fasting plasma glucose, blood pressure, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol. We used a random-effects meta-analysis model to estimate mean differences for continuous outcomes and risk ratio for dichotomous outcomes. We followed PICOS description model for defining eligibility and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) 2015 guidelines for reporting results. Of 3,190 citations, we included nine trials involving 10,974 participants. The pooled analysis showed no significant difference in all-cause mortality (risk ration [RR] = 0.93, 95% CI [0.52, 1.67]), serious adverse events (RR = 0.96, 95% CI [0.79, 1.17]) and adverse events (RR = 1.00, 95% CI [0.99, 1.02]) between the two, but in hypoglycemia (RR = 0.13, 95% CI [0.10, 0.17], P < 0.001). Participants taking metformin-sodium glucose cotransporter-2 inhibitors showed a significantly greater reduction in HbA1c (mean difference [MD] = − 0.10%, 95% CI [− 0.17, − 0.03], body weight (MD = − 4.57 kg, 95% CI [− 4.74, − 4.39], systolic blood pressure (MD = − 4.77 mmHg, 95% CI [− 5.39, − 4.16]), diastolic blood pressure (MD = − 2.07 mmHg, 95% CI [− 2.74, − 1.40], and fasting plasma glucose (MD = − 0.55 mmol/L, 95% CI [− 0.69, − 0.41]), p < 0.001. Combination therapy of metformin and sodium-glucose cotransporter-2 inhibitors is a safe and efficacious alternative to combination therapy of metformin and sulphonylureas for patients with type 2 diabetes who are at risk of cardiovascular comorbidity. However, there remains a need for additional long-term randomized controlled trials as available studies are very limited and heterogeneous.

Abstract
BACKGROUND The effects of sodium-glucose transporter 2 (SGLT2) inhibitors on cardiovascular death (CV death) and all-cause death (AC death) in patients with type 2 diabetes (T2D) and chronic kidney disease (CKD) are currently under intensive investigation. We intended to conduct an updated meta-analysis including the SCORED trial to evaluate the effects of SGLT2 inhibitors on death and cardiorenal events in this vulnerable population. METHODS Cardiorenal outcome trials of SGLT2 inhibitors were included. Primary outcomes were CV death and AC death, while secondary outcomes were hospitalization for heart failure (HHF), myocardial infarction (MI), CKD progression, cardiovascular death or hospitalization for heart failure (CV death or HHF), major adverse cardiovascular events (MACE), and stroke. Meta-analysis was conducted for each outcome. RESULTS Eight trials were included for meta-analysis. Compared with placebo, SGLT2 inhibitors significantly lowered the risk of CV death (HR = 0.86, 95% CI = 0.75-0.98), AC death (HR = 0.87, 95% CI = 0.79-0.96), HHF (HR = 0.64, 95% CI = 0.56-0.74), MI (HR = 0.76, 95% CI = 0.65-0.89), CKD progression (HR = 0.62, 95% CI = 0.54-0.72), and CV death or HHF (HR = 0.73, 95% CI = 0.67-0.80). No heterogeneity existed in the above meta-analyses (all I2 values = 0%), whereas moderate heterogeneity existed in the meta-analyses for MACE and stroke (I2 = 31.6% and 44.5%, respectively). CONCLUSIONS Our findings suggest that SGLT2 inhibitors versus placebo significantly lower death, heart failure, renal failure, and MI events in patients with T2D and CKD. Head-to-head trials are needed to examine the possible differences in the effects of various gliflozins on MACE and stroke.
