A Horse, a Jockey, and a Therapeutic Dilemma: Choosing the Best Option for a Patient with Diabetes and Coronary Artery Disease

Effect of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and structural changes following myocardial infarction: A systematic review and meta-analysis

BACKGROUND

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are anti-hyperglycemic drugs and have been proven to have cardiovascular protective effects for patients with heart failure regardless of their diabetes status. However, the benefit of SGLT2i following myocardial infarction (MI) remains incompletely established. This review aimed to investigate the impact of SGLT2i on NT-proBNP levels and structural changes post-MI.

METHOD

Medline, ClinicalTrial.gov, Scopus, and Directory of open-access journals were searched to retrieve the relevant articles. Eligible studies were randomized clinical trials that assessed NT-proBNP and cardiac structural changes in patients who received SGLT2i compared to placebo following MI. Two reviewers independently screened articles, extracted data, and assessed study quality.

RESULT

Four studies were included in this review, including patients with and without diabetes. While two studies showed no marked decrease from the baseline in NT-proBNP levels between the SGLT2i group and the control group, two studies reported a substantial reduction. The meta-analysis included three of these studies, with a total of 238 participants. The meta-analysis did not find a statistically significant drop in NT-proBNP levels post-MI in the SGLT2 inhibitors group compared to placebo (pooled SMD = 0.16, 95% CI 0.57-0.26, P 0.45). Furthermore, different echocardiographic parameters were reported in the included trials, yet no meta-analysis could be conducted to assess the influence of SGLT2i on cardiac remodeling post-MI.

CONCLUSION

SGLT2i did not result in a statistically significant reduction of NT-proBNP level subsequent to myocardial infarction. A knowledge gap exists regarding the impact of these agents on cardiac remodeling post-MI. Future high-quality clinical trials are needed to provide more robust evidence.

Management of type 2 diabetes in patients with compensated liver cirrhosis: Short of evidence, plenty of potential

BACKGROUND AND AIMS

Treatment of type 2 diabetes (T2D) in patients with compensated cirrhosis is challenging due to hypoglycemic risk, altered pharmacokinetics, and the lack of robust evidence on the risk/benefit ratio of various drugs. Suboptimal glycemic control accelerates the progression of cirrhosis, while the frequent coexistence of nonalcoholic fatty liver disease (NAFLD) with T2D highlights the need for a multifactorial therapeutic approach.

METHODS

A literature search was performed in Medline, Google Scholar and Scopus databases till July 2023, using relevant keywords to extract studies regarding the management of T2D in patients with compensated cirrhosis.

RESULTS

Metformin, sodium-glucose co-transporter-2 inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1 RA) are promising treatment options for patients with T2D and compensated liver cirrhosis, offering good glycemic control with minimal risk of hypoglycemia, while their pleiotropic actions confer benefits on NAFLD and body weight, and decrease cardiorenal risk. Sulfonylureas cause hypoglycemia, thus should be avoided, while in specific studies, dipeptidyl peptidase-4 inhibitors have been correlated with increased risk of decompensation and variceal bleeding. Despite the benefits of thiazolidinediones in nonalcoholic steatohepatitis, concerns about edema and weight gain limit their use in compensated cirrhosis. Insulin does not exert hepatotoxic effects and can be administered safely in combination with other drugs; however, the risk of hypoglycemia should be considered.

CONCLUSIONS

The introduction of new hepatoprotective diabetes drugs into clinical practice, including tirzepatide, SGLT2i, and GLP-1 RA, sets the stage for future trials to investigate the ideal therapeutic regimen for people with T2D and compensated cirrhosis.

The Current Place of DPP4 Inhibitors in the Evolving Landscape of Type 2 Diabetes Management: Is It Time to Bid Adieu?

During the last decade, the landscape of type 2 diabetes (T2D) management has been completely transformed, moving from a glucose-centric perspective to a holistic approach that also takes into account weight control and organ protection. Dipeptidyl peptidase-4 inhibitors (DPP4i) are oral agents that have been used for the treatment of T2D for almost 20 years. Although they present an excellent safety profile, including the risk of hypoglycemia, they lack the spectacular cardiorenal benefits and weight-loss effects of the newer antidiabetic agents. This poses the question of whether they still deserve a place in the arsenal of drugs against T2D. In this article, we use a hypothetical case scenario to illustrate possible patient profiles where DPP4i could prove useful in the clinical setting. We discuss the advantages and disadvantages of the category, focusing on glycemic control, weight management, and cardiorenal protection, which are the pillars of modern T2D management, also considering its safety profile and cost-effectiveness. We conclude that in most cases, DPP4i present a more favorable risk-benefit ratio compared to sulfonylureas, which are still widely prescribed throughout the world. We also suggest that future research should clarify the reasons behind the contradictory findings between human and animal studies on cardiorenal effects of the class and identify subgroups of patients who would derive most benefit with DPP4i treatment.

GLP-1 Receptor Agonists in Obese Patients with Inflammatory Bowel Disease: from Molecular Mechanisms to Clinical Considerations and Practical Recommendations for Safe and Effective Use

PURPOSE OF REVIEW

To discuss current literature and provide practical recommendations for the safe and effective use of glucagon-like peptide 1 receptor agonists (GLP-1 RA) in people with inflammatory bowel disease (IBD) and type 2 diabetes (T2D) and/or obesity. The molecular mechanisms that justify the potential benefits of GLP-1 RA in IBD and the links between IBD, obesity, and cardiovascular disease are also discussed.

RECENT FINDINGS

Preliminary data suggest that GLP-1 RA can modulate crucial pathways in the pathogenesis of IBD, such as chronic inflammation circuits, intestinal tight junctions, and gut microbiome dysbiosis, setting the stage for human trials to investigate the role of these agents in the treatment of IBD among people with or without diabetes and obesity. However, gastrointestinal side effects related to GLP-1 RA need appropriate clinical management to mitigate risks and maximize the benefits of therapy in people with IBD. GLP-1 RA originally emerged as drugs for the treatment of hyperglycemia and are currently licensed for the management of T2D and/or overweight/obesity. However, their wealth of pleiotropic actions soon raised expectations that they might confer benefits on non-metabolic disorders. Future studies are expected to clarify whether GLP-1 RA deserve an adjunct place in the arsenal of drugs against IBD.

Weight Loss Versus Glycemic Control as the Primary Treatment Target in Newly Diagnosed Type 2 Diabetes: Why Choose When You Can Have Both?

Weight loss has been associated with significant improvements in glycemic control, quality of life, and comorbidities in people with type 2 diabetes. Furthermore, achieving diabetes remission can reduce the risk of microvascular complications and mitigate the burden of diabetes on healthcare systems. However, preventing weight regain is challenging in the long term. Strict glycemic control, particularly in the early stages of the disease, can reduce the subsequent risk of microvascular complications and specific macrovascular endpoints in the long run; however, its impact on cardiovascular and all-cause mortality remains controversial. New classes of antidiabetic agents, namely glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, have been shown to reduce cardiorenal risk and induce weight loss, in addition to effectively lowering blood glucose with a minimal risk of hypoglycemia. Recently, it has been debated whether weight loss or glycemic control should be the first priority in people with a recent diagnosis of type 2 diabetes. This article aims to discuss the debate from a clinical perspective, evaluate the advantages and disadvantages of each therapeutic strategy, and assess the impact of both approaches on the future risk of diabetic complications, based on the latest evidence. Given that both goals are equally important, the authors suggest that merging the two strategies, with the early and aggressive use of combination therapies consisting of glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, will confer maximum benefits in terms of weight loss and glycemic control, and will reduce the future risk of complications from diabetes. A personalized approach that takes into account specific patient characteristics, including age, sex, race, frailty, and cognitive status, among others, can lead to more effective diabetes care.
