Strategies for Appropriate Selection of SGLT2-i vs. GLP1-RA in Persons with Diabetes and Cardiovascular Disease

Reduced mortality and morbidity associated with metformin and SGLT2 inhibitor therapy in patients with type 2 diabetes mellitus and cirrhosis

INTRODUCTION

Evidence for dual antidiabetic therapy in type 2 diabetes mellitus patients with cirrhosis is limited. This study compared 5-year mortality, composite hepatic decompensation risk, and hepatocellular carcinoma occurrence in patients with diabetes and cirrhosis who were either on metformin monotherapy or on dual metformin and sodium-glucose co-transporter-2 inhibitor (SGLT2-I) therapy.

METHODS

This retrospective study used the TriNetX Research Network to identify propensity score-matched patients treated with either metformin or dual metformin and SGLT2-I therapy. Our outcomes were all-cause mortality, a composite of hepatic decompensation events, and hepatocellular carcinoma (HCC) occurrence over 5 years. We estimated hazard ratios within each cohort with 95% confidence intervals (CI) and Kaplan-Meier estimates for time-to-event distributions with Log-rank tests. We were able to stratify our cohorts by age, sex, race, and ethnicity. We further investigated a subset of diabetic patients with cirrhosis due to MASH.

RESULTS

In our propensity score-matched cohorts of type 2 diabetes patients with cirrhosis, those on dual metformin and SGLT2-I therapy had decreased risk for mortality (HR 0.57, 95%CI 0.41-0.81), reduced composite risk of becoming decompensated (HR 0.63, 95%CI 0.43-0.93) and less than half the risk for developing HCC (HR 0.43, 95%CI 0.21-0.88) compared to those on mono metformin therapy. We did not find a difference between mono or dual therapy treatment for mortality, decompensation, or HCC risks in the subset of patients with MASH cirrhosis.

CONCLUSION

Dual metformin and SGLT2-I treatment in type 2 diabetes patients with cirrhosis are associated with improved mortality and hepatic complications.

Clinical cardiovascular phenotypes and the pattern of future events in patients with type 2 diabetes

IMPORTANCE

Updated guidelines on diabetes recommend targeting sodium-glucose cotransporter-2 inhibitors (SGLT2i) at patients at risk of heart failure (HF) and glucagon-like peptide-1 receptor agonists (GLP1-RA) at those at greater risk of atherothrombotic events.

OBJECTIVE

We estimated the risk of different cardiovascular events in patients with type 2 diabetes (T2D) and newly established cardiovascular disease.

DESIGN, SETTING AND PARTICIPANTS

Patients with T2D and newly established cardiovascular disease from 1998 to 2016 were identified using Danish healthcare registers and divided into one of four phenotype groups: (1) HF, (2) ischemic heart disease (IHD), (3) transient ischemic stroke (TIA)/ischemic stroke, and (4) peripheral artery disease (PAD). The absolute 5-year risk of the first HF- or atherothrombotic event occurring after inclusion was calculated, along with the risk of death.

MAIN OUTCOMES AND MEASURES

The main outcome was the first event of either HF or an atherothrombotic event (IHD, TIA/ischemic stroke or PAD) in patients with T2D and  new-onset cardiovascular disease.

RESULTS

Of the 37,850 patients included, 40% were female and the median age was 70 years. Patients with HF were at higher 5-year risk of a subsequent HF event (17.9%; 95% confidence interval (CI) 17.1-18.8%) than an atherothrombotic event (15.8%; 15.0-16.6%). Patients with IHD were at higher risk of a subsequent atherothrombotic event (24.6%; 23.9-25.3%) than developing HF, although the risk of HF was still substantial (10.6%; 10.2-11.1%). Conversely, patients with PAD were at low risk of developing HF (4.4%; 3.8-5.1%) but at high risk of developing an atherothrombotic event (15.9%; 14.9-17.1%). Patients with TIA/ischemic stroke had the lowest risk of HF (3.2%; 2.9-3.6%) and the highest risk of an atherothrombotic event (20.6%; 19.8-21.4).

CONCLUSIONS

In T2D, a patient's cardiovascular phenotype can help predict the pattern of future cardiovascular events.

A Review on the Efficacy and Safety of Oral Semaglutide

There are numerous treatment options currently available for patients with type 2 diabetes mellitus; however, a multitude of patients continue to have inadequately controlled glycemic levels with their current antihyperglycemic regimen. Furthermore, the American Diabetes Association guidelines increasingly highlight the importance of multifactorial management and optimizing medication regimens that include cardiovascular, renal, and/or weight benefits in patients with type 2 diabetes mellitus. Glucagon-like peptide-1 receptor agonists belong to a novel class of type 2 diabetes mellitus agents that are becoming increasingly prevalent owing to their ability to improve glycemic status without the risk of hypoglycemia. Currently, there are three US Food and Drug Administration-approved glucagon-like peptide-1 receptor agonists, subcutaneous semaglutide, dulaglutide, and liraglutide, that also have an indication for reducing major adverse cardiovascular events in patients with type 2 diabetes mellitus and established cardiovascular disease. However, these agents are not often the first options because of their subcutaneous administration. Nevertheless, co-formulation of oral semaglutide with an absorption enhancer has shown to increase its bioavailability and has made its oral absorption possible. In the PIONEER trials, oral semaglutide effectively lowered blood glucose levels, and showed benefits on weight and cardiovascular outcomes; however, there is no Food and Drug Administration indication approved yet as the SOUL trial is still ongoing. Such characteristics of oral semaglutide may improve and increase its use compared to subcutaneous agents and possibly lead to earlier cardiovascular protection in addition to achieving glycemic control.

The new type 2 diabetes mellitus therapy: comparison between the two classes of drugs GLPR (glucagon-like peptide receptor) agonists and SGLT2 (sodium-glucose cotransporter 2) inhibitors

Type 2 diabetes mellitus represents one of the most common chronic-degenerative diseases in modern society and is the cause of innumerable micro- and macrovascular complications that weigh on the national health system. Until a few years ago, there was no anti-diabetic drug that, in addition to lowering blood sugar, had an impact on cardiovascular risk in these patients. In this report, we will analyse the characteristics, contraindications, and evidence in favour of the use of two innovative categories of molecules that aim, for the first time in history, at controlling blood sugar levels and simultaneously lower cardiovascular risk in diabetics individuals: the glucagon-like peptide receptor agonists and the sodium–glucose cotransporter 2 inhibitors.
