National Trends in Use of Sodium-Glucose Cotransporter-2 Inhibitors and Glucagon-like Peptide-1 Receptor Agonists by Cardiologists and Other Specialties, 2015 to 2020

GLP-1-ra and heart failure-related outcomes in patients with and without history of heart failure: an updated systematic review and meta-analysis

AIMS

Glucagon-like peptide-1 receptor agonists (GLP1-ra) have shown to reduce cardiovascular (CV) events in patients with diabetes, including heart failure (HF) hospitalizations. However, whether such benefit consistently occurs in patients with history of HF remains uncertain. We performed a systematic review and meta-analysis to assess the impact of GLP1-ra on CV outcomes in patients with and without HF history.

METHODS AND RESULTS

All randomized, placebo-controlled trials evaluating GLP1-ra and reporting CV outcomes stratified by HF history were searched in Pubmed from inception to November 12th, 2023. The primary outcome was HF hospitalizations. Secondary outcomes included CV death, the composite of CV death and hospitalizations for HF, and major adverse cardiovascular events (MACE). Hazard ratio (HR) and 95% confidence interval (CIs) were used as effect estimates and calculated with a random-effects model. 68,653 patients (GLP1-ra = 34,301, placebo = 34,352) from 10 trials were included. GLP1-ra reduced HF hospitalization (no HF: HR = 0.79, 95% CI 0.63-0.98; HF: HR = 1.00, 95% CI 0.82-1.24, pinteraction = 0.12), CV death (no HF: HR = 0.81, 95% CI 0.71-0.92; HF: HR = 0.97, 95% CI 0.81-1.15, pinteraction = 0.11), and the composite of HF hospitalizations and CV death (no HF: HR = 0.80, 95% CI 0.72-0.89; HF: HR = 1.00 95% CI 0.88-1.15, pinteraction = 0.010) only in patients without history of HF, despite a significant interaction between HF history and treatment effect was detected only for the latter. MACE were reduced in both subgroups without significant interaction between HF history and treatment effect (no HF: HR = 0.86, 95% CI 0.78-0.96; HF: HR = 0.83, 95% CI 0.72-0.95, pinteraction = 0.69).

CONCLUSION

GLP1-ra do not decrease HF-hospitalization risk, despite a potential benefit in patients without history of HF, but are effective in reducing ischemic events irrespective of the presence of HF. PROSPERO-registered (CRD42022371264).

Underuse of GLP-1 receptor agonists in the management of type 2 diabetes despite a favorable benefit-safety profile

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.

A New Age for Secondary Prevention: Optimal Medical Therapy for Stable Ischemic Heart Disease Among Patients with Diabetes and/or Obesity

Patients with type 2 diabetes and/or obesity and established cardiovascular disease are at increased risk for recurrent cardiovascular events. The indications of glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter-2 inhibitors have been expanded in the last decade due to benefit in cardiovascular outcome trials and are now considered guideline-recommended therapy for patients with type 2 diabetes and cardiovascular disease. Emerging data have begun to suggest that GLP-1RAs can decrease major adverse cardiovascular events among patients with obesity without diabetes. Overall, prescription of these agents remains low, despite being key to improve disparities in recurrent cardiovascular events. In this review, we discuss optimal medical therapy for secondary prevention for stable ischemic heart disease.

Cardiovascular Outcomes With Empagliflozin and Dapagliflozin in Patients Without Diabetes

Although the cardiovascular (CV) benefits of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with diabetes mellitus (DM) are well known, their effects in patients without DM continue to be explored. We provide a meta-analysis of the available evidence. Online databases were searched for randomized controlled trials (RCTs) comparing SGLT2i to placebo/control in patients without DM. The end points of interest were composite CV death/hospitalization for heart failure (HF) with individual components, all-cause death, major adverse CV events, and serious adverse events. Subgroup analysis was performed according to the type of SGLT2i. Pooled odds ratios (OR) and 95% confidence intervals (CI) were generated through a random-effects model. A total of 6 RCTs with 12,984 patients (6,501 in the SGLT2i group and 6,483 in the placebo group) were included, followed over a mean duration of 17.7 months. Four RCTs had patients with HF, 1 with chronic kidney disease, and 1 with myocardial infarction. The mean age was 64 years, 72% of patients were men and mean hemoglobin A1C was 5.7%. As compared with a placebo, SGLT2i treatment was associated with significant reduction in composite CV death or hospitalization for HF (OR 0.77, 95% CI 0.68 to 0.87, p <0.0001), primarily because of a decrease in hospitalization for HF (OR 0.70, 95% CI 0.60 to 0.81, p <0.00001). No significant differences were found pertaining to CV death (OR 0.86, 95% CI 0.74 to 1.01, p = 0.06), all-cause death (OR 0.89, 95% CI 0.71 to 1.11, p = 0.29) and major adverse CV events (OR 0.95, 95% CI 0.68 to 1.32, p = 0.75). Serious adverse events were lower with use of empagliflozin vs placebo. In conclusion, this study shows significant CV benefits in terms of reduction in CV death or hospitalization for HF in patients without DM treated with SGLT2i as compared with placebo. The underlying heterogeneity of patients in terms of co-morbidities (HF, chronic kidney disease, or myocardial infarction) needs to be considered while interpreting the results.

Prolonged Diabetic Ketoacidosis Associated With Sodium-Glucose Cotransporter-2 Inhibitors: A Review of Postmarketing Cases

OBJECTIVE

To describe reported cases of prolonged or relapsed ketoacidosis (KA) in adults with type 2 diabetes receiving treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors.

METHODS

We performed a search of the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System and medical literature, to identify our case series and to characterize cases of prolonged KA, relapsed KA, or persistent ketonemia, persistent ketonuria and/or persistent glucosuria in adults receiving SGLT2 inhibitors.

RESULTS

The FDA identified 29 unique cases of prolonged or relapsed KA, as well as related terms persistent ketonemia, persistent ketonuria, and persistent glucosuria, in patients receiving SGLT2 inhibitors through July 26, 2022. The patients ranged in age from 26 to 85 years. Treatment duration of KA ranged from 3 to 20 days. There were 7 cases of relapsed KA when insulin was reduced or transitioned to subcutaneous route. Arterial pH value was 7.0 or below in 4 patients, and the median pH was 7.1. Associated factors for prolonged or relapsed KA included surgery, decreased caloric intake, and ketogenic/carbohydrate restricted diet. A total of 62% of the patients were taking 3 or more glycemic control medications including the SGLT2 inhibitor. All patients with sufficient follow-up information recovered.

CONCLUSION

Although KA is a well-known risk associated with SGLT2 inhibitors, this case series demonstrated the potential for prolonged or recurrent KA events with serious outcomes. These cases informed updates to FDA's prescribing information to inform prescribers of this risk.

A cohort study of sodium-glucose cotransporter-2 inhibitors after acute kidney injury among Veterans with diabetic kidney disease

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) reduce the risk for several adverse outcomes among patients with diabetic kidney disease. Yet, optimal timing for SGLT2i after acute kidney injury (AKI) is uncertain, as are the providers responsible for post-AKI SGLT2i initiation. Using a retrospective cohort of United States Veterans with diabetes mellitus type 2 and proteinuria, we examined encounters by provider specialty before SGLT2i initiation and subsequent all-cause mortality after hospitalization with AKI, defined by a 50% or more rise in serum creatinine. Covariates included recovery, defined by return to a 110% or less of baseline creatinine, and time since AKI hospitalization. Among 21,330 eligible Veterans, 7,798 died (37%) and 6,562 received a SGLT2i (31%) over median follow-up of 2.1 years. Post-AKI SGLT2i use was associated with lower mortality risk [adjusted hazard ratio 0.63 (95% confidence interval 0.58-0.68)]. Compared with neither SGLT2i use nor recovery, mortality risk was similar with recovery without SGLT2i use [0.97 (0.91-1.02)] but was lower without recovery prior to SGLT2i use [0.62 (0.55-0.71)] and with SGLT2i use after recovery [0.60 (0.54-0.67)]. Finally, the effect of SGLT2i was stable over time (P for time-interaction 0.19). Thus, we observed reduced mortality with SGLT2i use after AKI among Veterans with diabetic kidney disease whether started earlier or later or before or after observed recovery. Hence, patients with diabetic kidney disease who receive a SGLT2i earlier after AKI experience no significant harm impacting mortality and experience a lower mortality risk than those who do not.

Dysphagia as a Manifestation of Endocrine and Metabolic Disorders

Dysphagia is a common manifestation of endocrine and metabolic diseases. Swallowing is a complex neuromuscular process, with an interplay of sensory and motor function, that has voluntary and involuntary control. Disruptions in any of these processes can cause significant dysphagia. Endocrine disorders and metabolic derangements are systemic conditions that affect multiple organ systems. They contribute to the development of neuropathies, myopathies, and motility disorders that lead to swallowing difficulty. Malnutrition and critical illness can lead to deconditioning and atrophy which can cause dysphagia, which in turn can lead to further malnutrition and deconditioning.

'We are somehow fixated on this being a diabetes drug': a qualitative study exploring the views of cardiologists and nephrologists about sodium-glucose cotransporter 2 inhibitor initiation

BACKGROUND

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are now indicated for heart failure and chronic kidney disease (CKD), irrespective of the presence of diabetes. Hence, cardiologists and nephrologists have an important role in initiating these drugs.

AIMS

To explore cardiologists' and nephrologists' perspectives regarding initiating SGLT2i and their safety monitoring practices when initiating SGLT2i.

METHODS

Purposive and snowball approaches were used to recruit participants working in diverse areas in New South Wales, Australia. Semi-structured interviews were conducted with 12 cardiologists and 12 nephrologists. Interviews were conducted until thematic saturation was reached. Emergent themes were identified from transcripts. An iterative general inductive approach was used for data analysis.

RESULTS

There was a reluctance amongst most non-heart-failure subspecialist cardiologists to initiate SGLT2i. Reasons included the perception of SGLT2i as diabetes drugs, concern about side effects, lack of experience and issues with follow-up. In contrast, nephrologists reported feeling confident to initiate SGLT2i. Nephrologists varied in their opinions about the severity of CKD at which SGLT2i initiation was reasonable and monitoring of renal function following initiation. Government subsidisation was an important factor in the decision to prescribe SGLT2i to people without diabetes.

CONCLUSIONS

Our findings highlight the complex transition from the perception of SGLT2i as diabetes drugs to cardiometabolic and reno-protective agents. Interdisciplinary collaboration may enable greater confidence amongst specialists to initiate SGLT2i, including in patients with CKD. Additionally, there is a need for clear and detailed guidance about SGLT2i prescription in patients with renal dysfunction and renal function monitoring following SGLT2i initiation.

Appendicitis: A Hidden Danger of GLP-1 Receptor Agonists?

Introduction: While glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have become increasingly prescribed, use is often inhibited by the gastrointestinal adverse effects that patients must endure. Nausea, vomiting, and cholelithiasis are most commonly associated with use, with little to no data or labeling reflecting risk of appendicitis or associated symptoms. Appendicitis etiology is theorized to develop secondary to obstruction of the vermiform via infection or fecalith causing an increase in intraluminal pressure. It is hypothesized that given the aforementioned gastrointestinal effects associated with GLP-1 RAs, patients taking such agents may be more at risk for developing this acute condition. Patient Case: We describe a case of a 48-year-old woman who presented to the emergency department several months after being initiated on Ozempic (semaglutide). This report aims to analyze the potential secondary adverse effects that may result from GLP-1 RA use. Her examination was positive for focal abdominal tenderness and leukocytosis along with imaging suggestive of appendicitis. Her acute condition ultimately required an appendectomy. Discussion: While minimal data are available to suggest significant causation between GLP-1 RAs and appendicitis, a literature and database search revealed that instances may be more common than previously thought. Conclusion: Trial results and adverse event reporting systems report an infrequent incidence in patients using these medications, but this report aims to contribute to the literature describing this potential adverse event.

The clinical benefits of sodium-glucose cotransporter type 2 inhibitors in people with gout

Gout is the most common form of inflammatory arthritis worldwide and is characterized by painful recurrent flares of inflammatory arthritis that are associated with a transiently increased risk of adverse cardiovascular events. Furthermore, gout is associated with multiple cardiometabolic-renal comorbidities such as type 2 diabetes, chronic kidney disease and cardiovascular disease. These comorbidities, potentially combined with gout flare-related inflammation, contribute to persistent premature mortality in gout, independently of serum urate concentrations and traditional cardiovascular risk factors. Although better implementation of standard gout care could improve gout outcomes, deliberate efforts to address the cardiovascular risk in patients with gout are likely to be required to reduce mortality. Sodium-glucose cotransporter type 2 (SGLT2) inhibitors are approved for multiple indications owing to their ability to lower the risk of all-cause and cardiovascular death, hospitalizations for heart failure and chronic kidney disease progression, making them an attractive treatment option for gout. These medications have also been shown to lower serum urate concentrations, the causal culprit in gout risk, and are associated with a reduced risk of incident and recurrent gout, potentially owing to their purported anti-inflammatory effects. Thus, SGLT2 inhibition could simultaneously address both the symptoms of gout and its comorbidities.

Sociodemographic disparities in sodium-glucose cotransporter-2 inhibitor use among US kidney transplant recipients: An observational study of real-world pharmacy records

BACKGROUND

Recent clinical trials demonstrate benefits of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients with chronic kidney disease, but data on use in kidney transplant (KTx) recipients are limited.

METHODS

We examined a novel database linking SRTR registry data for KTx recipients (2000-2021) with outpatient fill records from a large pharmaceutical claims warehouse (2015-2021). Adult (≥18 years) KTx recipients treated with SGLT2i were compared to those who received other noninsulin diabetes medications without SGLT2i. Characteristics associated with SGLT2i use were quantified by multivariable logistic regression (adjusted odds ratio, 95%LCLaOR95%UCL).

RESULTS

Among 18 988 KTx recipients treated with noninsulin diabetes agents in the study period, 2224 filled an SGLT2i. Mean time from KTx to prescription was 6.7 years for SGLT2i versus 4.7 years for non-SGLT2i medications. SGLT2i use was more common in Asian adults (aOR, 1.091.311.58) and those aged > 30-59 years (compared with 18-30 years) or with BMI > 35 kg/m2 (aOR, 1.191.411.67), and trended higher with self-pay status. SGLT2i use was lower among KTx recipients who were women (aOR, .79.87.96), Black (aOR, .77.881.00) and other (aOR, .52.751.07) race, publicly insured (aOR, .82.921.03), or with less than college education (aOR, .78.87.96), and trended lower in those age 75 years and older. SGLT2i use in KTx patients increased dramatically in 2019-2021 (aOR, 5.015.636.33 vs. prior years).

CONCLUSION

SGLT2i use is increasing in KTx recipients but varies with factors including race, education, and insurance. While ongoing study is needed to define risks and benefits of SGLT2i use in KTx patients, attention should also focus on reducing treatment disparities related to sociodemographic traits.

The Interconnectedness of Euglycemic Diabetic Ketoacidosis With Concomitant Thyroid Storm: A Case Report

Sodium-glucose transport protein 2 inhibitors (SGLT2i) are becoming commonplace in many chronic diseases: type 2 diabetes mellitus, heart failure, and chronic kidney disease. We present the case of a 65-year-old male with a history of type 2 diabetes who had been on an SGLT2i for over 12 months and was found to have euglycemic diabetic ketoacidosis (eDKA) occurring concurrently with a thyroid storm. This case report illustrates a unique scenario of two endocrine emergencies occurring simultaneously.

Glucagon-like peptide-1 receptor agonist and sodium-glucose cotransporter 2 inhibitor use among adults with diabetes mellitus by cardiovascular-kidney disease risk: National Health and Nutrition Examination Surveys, 2015-2020

Objective

Glucagon-like peptide-1 receptor agonists (GLP1-RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2Is) lower adverse cardiac and kidney events among high-risk patients with diabetes mellitus (DM) and are now guideline-recommended as first-line therapy alongside metformin. However, the adoption of these new treatments from 2015 to 2020 among the highest-risk adults with DM remains unclear.

Methods

We performed a cross-sectional analysis of the National Health and Nutrition Examination Surveys (NHANES) 2015-2020 to estimate the use of GLP1-RAs and SGLT2Is among adults with DM overall and by level of cardiovascular and kidney risk (CKR). We defined high CKR by history of atherosclerotic cardiovascular disease (ASCVD), chronic kidney disease (CKD), heart failure, or age ≥55 years with at least 2 ASCVD risk factors (i.e., obesity, hypertension, hyperlipidemia, or current smoker).

Results

Overall, 2,432 participants with DM (mean age 60.6 years, 46.8 % female, 58.8 % Non-Hispanic White) were included, of which 1,869 and 563 were with and without high CKR, respectively. Participants with vs. without high CKR were more likely to be older, have higher systolic blood pressure, lower estimated glomerular filtration rate, use oral antidiabetic agents, and have health insurance. Overall, the weighted prevalence of GLP1-RA or SGLT2I was 9.0 % (95 % confidence interval [CI] 6.9-11.0): 4.8 % (95 % CI 3.6-6.1) took GLP1-RAs, and 5.1 % (95 % CI 3.3-7.0) took SGLT2Is. Use of GLP1-RAs or SGLT2Is did not differ between participants with vs. without high CKR (adjusted prevalence ratio [aPR] 1.00; 95 % CI 0.98-1.02). Participants with ASCVD were more likely to be on a GLP1-RA or SGLT2I (aPR 1.28; 95 % CI 1.25-1.31), while adults with CKD were less likely (aPR 0.84; 95 % CI 0.82-0.86).

Conclusion

Among US adults with DM, GLP1-RA and SGLT2I use was low regardless of CKR. Data since 2020 analyzing the utilization of GLP1-RAs and SGLT2Is among high-CKR patients with DM is needed to identify implementation strategies for increased utilization.

Impact of Residential Social Deprivation on Prediction of Heart Failure in Patients With Type 2 Diabetes: External Validation and Recalibration of the WATCH-DM Score Using Real World Data

BACKGROUND

Patients with type 2 diabetes are at risk of heart failure hospitalization. As social determinants of health are rarely included in risk models, we validated and recalibrated the WATCH-DM score in a diverse patient-group using their social deprivation index (SDI).

METHODS

We identified US Veterans with type 2 diabetes without heart failure that received outpatient care during 2010 at Veterans Affairs medical centers nationwide, linked them to their SDI using residential ZIP codes and grouped them as SDI <20%, 21% to 40%, 41% to 60%, 61% to 80%, and >80% (higher values represent increased deprivation). Accounting for all-cause mortality, we obtained the incidence for heart failure hospitalization at 5 years follow-up; overall and in each SDI group. We evaluated the WATCH-DM score using the C statistic, the Greenwood Nam D'Agostino test χ2 test and calibration plots and further recalibrated the WATCH-DM score for each SDI group using a statistical correction factor.

RESULTS

In 1 065 691 studied patients (mean age 67 years, 25% Black and 6% Hispanic patients), the 5-year incidence of heart failure hospitalization was 5.39%. In SDI group 1 (least deprived) and 5 (most deprived), the 5-year heart failure hospitalization was 3.18% and 11%, respectively. The score C statistic was 0.62; WATCH-DM systematically overestimated heart failure risk in SDI groups 1 to 2 (expected/observed ratios, 1.38 and 1.36, respectively) and underestimated the heart failure risk in groups 4 to 5 (expected/observed ratios, 0.95 and 0.80, respectively). Graphical evaluation demonstrated that the recalibration of WATCH-DM using an SDI group-based correction factor improved predictive capabilities as supported by reduction in the χ2 test results (801-27 in SDI groups I; 623-23 in SDI group V).

CONCLUSIONS

Including social determinants of health to recalibrate the WATCH-DM score improved risk prediction highlighting the importance of including social determinants in future clinical risk prediction models.

Renal outcomes after contrast exposure in patients with diabetes who use sodium-glucose cotransporter 2 inhibitors

BACKGROUND

Contrast-induced nephropathy has become increasingly prevalent as the age and prevalence of comorbidities in the general population have increased. Most cases of contrast-induced nephropathy are reversible; however, some may progress to acute kidney disease, and subsequently, to chronic kidney disease. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are known for their renoprotective effects. However, whether the use of these inhibitors affects the risk of contrast-induced kidney injury remains unclear.

METHODS

Data were collected from the Taipei Medical University Clinical Research Database. We included patients with diabetes who had contrast exposure between 2016 and 2020 because of computed tomography or coronary angiography. The primary outcome was the risk of a major adverse kidney event (MAKE), which encompassed acute kidney disease, chronic kidney disease progression, and the need for renal replacement therapy. Overlap weighting was performed to reduce the effects of potential confounders.

RESULTS

This study included 12 421 patients, who were divided into two groups: SGLT2i users (n = 920) and nonusers (n = 11 501). The follow-up period after contrast exposure was 6 months. The risk of a MAKE was lower in SGLT2i users than in nonusers (incidence, 36.9 vs. 49.9 per 1000 person-months, respectively; P = .0011). Furthermore, the incidence of acute kidney disease or chronic kidney disease progression was significantly lower in the SGLT2i users than in nonusers. However, no significant between-group difference was noted in the incidence of other MAKEs.

CONCLUSIONS

SGLT2i may be safely used in diabetic patients needing contrast exposure. The risk of a MAKE may be lower in SGLT2i users than in nonusers.

Applying the ABCs of Cardiovascular Disease Prevention to the 2023 AHA/ACC Multisociety Chronic Coronary Disease Guidelines

The 2023 American Heart Association/American College of Cardiology Multisociety Guideline for the Management of Patients with Chronic Coronary Disease provides updated recommendations for the management of chronic coronary disease. The term "chronic coronary disease" reflects the lifelong nature of the disease and diverse disease etiologies that come under the chronic coronary disease umbrella, beyond the presence of epicardial coronary stenosis, which require targeted lifestyle recommendations, serial optimization of medications, and involvement of multiple care team members. In this review, we highlight several areas where a collaborative approach between cardiologists, primary care clinicians, and internists is essential to optimize the care of patients with chronic coronary disease.

Trends and site-level variation of novel cardiovascular medication utilization among patients admitted for heart failure or coronary artery disease in the US Veterans Affairs System: 2017-2021

BACKGROUND

We assessed trends in novel cardiovascular medication utilization in US Veterans Affairs (VA) for angiotensin receptor-neprilysin inhibitors (ARNI), sodium-glucose cotransporter-2 Inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1 RA).

METHODS

We retrospectively identified cohorts from 114 VA hospitals with admission for prevalent 1) systolic heart failure (HF, N = 82,375) or 2) coronary artery disease and diabetes (CAD+T2D, N = 74,209). Site-level data for prevalent filled prescriptions were assessed at hospital admission, discharge, or within 6 months of discharge. Variability among sites was estimated with median odds ratios (mOR), and within-site Pearson correlations of utilization of each medication class were calculated. Site- and patient-level characteristics were compared by high-, mixed-, and low-utilizing sites.

RESULTS

ARNI and SGTL2i use for HF increased from <5% to 20% and 21%, respectively, while SGTL2i or GLP-1 RA use for CAD+T2D increased from <5% to 30% from 2017 to 2021. Adjusted mOR and 95% confidence intervals for ARNI, SGTL2i for HF, and SGTL2i or GLP-1 RA for CAD+T2D were 1.73 (1.64-1.91), 1.72 (1.59-1.81), and 1.53 (1.45-1.62), respectively. Utilization of each medication class correlated poorly with use of other novel classes (Pearson <0.38 for all). Higher patient volume, number of beds, and hospital complexity correlated with high-utilizing sites.

CONCLUSIONS

Utilization of novel medications has increased over time but remains suboptimal for US Veterans with HF and CAD+T2D, with substantial site-level heterogeneity despite a universal medication formulary and low out-of-pocket costs for patients. Future work should include further characterization of hospital- and clinician-level practice patterns to serve as targets to increase implementation.

Tirzepatide attenuates mammary tumor progression in diet-induced obese mice

We report for the first time an anticancer benefit of tirzepatide-a dual glucagon-like peptide 1 and glucose-dependent insulinotropic polypeptide receptor agonist-in a model of obesity and breast cancer in female mice. Long-term tirzepatide treatment induced weight loss, mitigated obesity-driven changes in circulating metabolic hormone levels, and suppressed orthotopic E0771 mammary tumor growth. Relative to tirzepatide, chronic calorie restriction, an established anticancer intervention in preclinical models, promoted even greater weight loss, systemic hormonal regulation, and tumor suppression. We conclude that tirzepatide represents a promising pharmacologic approach for mitigating the procancer effects of obesity. Moreover, strategies promoting greater weight loss than achieved with tirzepatide alone may augment the anticancer benefits of tirzepatide.

Pharmacist-driven outreach initiative to increase prescribing of sodium-glucose cotransporter-2 inhibitors in eligible VHA patients with chronic kidney disease: a study protocol

BACKGROUND

Patients with chronic kidney disease (CKD) are at increased risk for multiple adverse events, several of which have been proven to be less likely with the use of sodium-glucose cotransporter-2 inhibitors (SGLT2i). As a result, guidelines now recommend SGLT2i be given to those with mild to moderate CKD and type 2 diabetes. The objective of this study is to evaluate if a pharmacist-driven SGLT2i prescribing initiative among eligible patients with CKD and diabetes within the VA could more rapidly improve the adoption of SGLT2i via a pragmatic approach aligned with learning health systems.

METHODS

Eligible patients will be identified through an established VA diabetes dashboard. Veterans with an odd social security number (SSN), which is effectively a random number, will be the intervention group. Those with even SSNs will serve as the control while awaiting a second iteration of the same interventional program. The intervention will be implemented in a rolling fashion across one Veterans Integrated Service Network. Our primary outcome is initiation of an SGLT2i. Secondary outcomes will include medication adherence and safety-related outcomes.

DISCUSSION

This project tests the impact of a pharmacist-driven medication outreach initiative as a strategy to accelerate initiation of SGLT2i. The results of this work will not only illustrate the effectiveness of this strategy for SGLT2is but may also have implications for increasing other guideline-concordant care. Furthermore, the utilization of SSNs to select Veterans for the first wave of this program has created a pseudo-randomized interventional trial supporting a pragmatic learning health system approach.

Perioperative Management of Patients Receiving Sodium-Glucose Cotransporter 2 Inhibitors: Development of a Clinical Guideline at a Large Academic Medical Center

The use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) is increasing rapidly for patients with diabetes, heart failure, and chronic kidney disease. These medications can cause euglycemic diabetic ketoacidosis in the perioperative period, and the Food and Drug Administration recently updated their recommendations that they be held for at least 3-to-4 days preoperatively. There is a paucity of guidelines for the perioperative management of patients taking SGLT2i who present for emergent surgery or elective surgery having not held the medications per Food and Drug Administration guidelines. At the University of Pennsylvania, a multidisciplinary team from the Departments of Anesthesiology, Endocrinology, and Pharmacy has developed comprehensive guidelines detailing preoperative, intraoperative, and postoperative management for patients using these medications. In this article, the authors present these guidelines and discuss challenges encountered while implementing them at a large academic medical center with satellite hospitals and surgery centers with varying resources and patient populations.

Molecular mechanisms underlying sarcopenia in heart failure

The loss of skeletal muscle, also known as sarcopenia, is an aging-associated muscle disorder that is disproportionately present in heart failure (HF) patients. HF patients with sarcopenia have poor outcomes compared to the overall HF patient population. The prevalence of sarcopenia in HF is only expected to grow as the global population ages, and novel treatment strategies are needed to improve outcomes in this cohort. Multiple mechanistic pathways have emerged that may explain the increased prevalence of sarcopenia in the HF population, and a better understanding of these pathways may lead to the development of therapies to prevent muscle loss. This review article aims to explore the molecular mechanisms linking sarcopenia and HF, and to discuss treatment strategies aimed at addressing such molecular signals.

Abolishing β-arrestin recruitment is necessary for the full metabolic benefits of G protein-biased glucagon-like peptide-1 receptor agonists

AIM

Earlier studies have shown that peptide glucagon-like peptide-1 receptor (GLP-1R) agonists with reduced β-arrestin recruitment show enhanced anti-hyperglycaemic efficacy through avoidance of GLP-1R desensitization. However, the ligand modifications needed to decrease β-arrestin recruitment usually also reduces GLP-1R affinity, therefore higher doses are needed. Here we aimed to develop new, long-acting, G protein-biased GLP-1R agonists with acute signalling potency comparable with semaglutide, to provide insights into specific experimental and therapeutic scenarios.

New GLP-1R agonist peptides were assessed using a variety of in vitro and in vivo assays.

RESULTS

First, we show that very substantial reductions in β-arrestin recruitment efficacy are required to realize fully the benefits of GLP-1R agonism on blood glucose lowering in mice, with more moderate reductions being less effective. Secondly, our lead compound (SRB107) performs substantially better than semaglutide for effects on blood glucose and weight loss, which may be jointly attributable to its biased agonist action and protracted pharmacokinetics. Thirdly, we show that biased agonist-specific GLP-1R internalization profiles occur at clinically relevant pharmacological concentrations. Finally, we show that SRB107 cAMP signalling is differentially modulated by single and double GLP1R coding variants seen in human populations, with implications for GLP-1R agonist pharmacogenomics.

CONCLUSIONS

Completely abolishing β-arrestin recruitment improves the anti-hyperglycaemic effects of GLP-1R agonists in mice.

Emerging Medical Therapies for the Treatment of Obesity in Women with Cardiovascular Diseases

PURPOSE OF REVIEW

In this review, the impact of obesity on cardiovascular disease in women and emerging anti-obesity pharmacologic treatments are discussed.

RECENT FINDINGS

Robust evidence demonstrates the burden of obesity across the lifespan in women and links obesity to a diverse set of cardiovascular diseases. Female-specific risk factors including sex hormones and pregnancy factors intersect with obesity and cardiovascular risk. Sustained weight loss has potential for cardiovascular benefits. Recent trials demonstrate cardiovascular benefits of emerging agents with weight loss effects including GLP-1 RA and SGLT2 inhibitors in women. Treatment and prevention strategies for cardiovascular disease in obese women should include integration of weight management strategies including the targeted use of emerging pharmacologic therapies.

Utilization and impact of SLGT2 inhibitors among diabetes patients in a nationally representative survey: Findings from NHANES 2013-2020

BACKGROUND AND AIMS

The purpose of this study is to examine patterns of utilization for antidiabetic medications among a nationally representative sample of the US population following the introduction of SGLT2 inhibitors in 2013.

METHODS

The study utilized National Health and Nutrition Examination Survey (NHANES) data from 2013 to 2020 to identify adult patients with diabetes using antidiabetic medication. The proportion of patients with diabetes using different antidiabetic medications, including SGLT2 inhibitors, was plotted over time. To assess the statistical significance of the utilization trend of SGLT2 inhibitors and other oral antidiabetics, logistic regression models were employed.

RESULTS

A weighted total of 26,421,357 individuals included in our study were diagnosed with diabetes. Among these, 18,751,659 diabetes patients were identified as medication users, with 1,058,686 (5.7 %) of them taking SGLT2 inhibitors. Over the 7-year study period, the percentage of patients taking SGLT2 inhibitors increased 21-fold, from 0.4 % in 2013-2014 to 9.4 % in 2017-2020. Despite this substantial increase, the utilization of other second-line antidiabetic agents, such as sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and TZDs, remained relatively stable during the same period.

CONCLUSIONS

SGLT2 inhibitor utilization has significantly increased among US diabetes patients; however, their rise has not substantially impacted the use of other second-line antidiabetic agents. Further research is needed to understand the social determinants and potential barriers affecting the broader adoption of these beneficial medications.

Multinational patterns of second line antihyperglycaemic drug initiation across cardiovascular risk groups: federated pharmacoepidemiological evaluation in LEGEND-T2DM

Objective

To assess the uptake of second line antihyperglycaemic drugs among patients with type 2 diabetes mellitus who are receiving metformin.

Design

Federated pharmacoepidemiological evaluation in LEGEND-T2DM.

Setting

10 US and seven non-US electronic health record and administrative claims databases in the Observational Health Data Sciences and Informatics network in eight countries from 2011 to the end of 2021.

Participants

4.8 million patients (≥18 years) across US and non-US based databases with type 2 diabetes mellitus who had received metformin monotherapy and had initiated second line treatments.

Exposure

The exposure used to evaluate each database was calendar year trends, with the years in the study that were specific to each cohort.

Main outcomes measures

The outcome was the incidence of second line antihyperglycaemic drug use (ie, glucagon-like peptide-1 receptor agonists, sodium-glucose cotransporter-2 inhibitors, dipeptidyl peptidase-4 inhibitors, and sulfonylureas) among individuals who were already receiving treatment with metformin. The relative drug class level uptake across cardiovascular risk groups was also evaluated.

Results

4.6 million patients were identified in US databases, 61 382 from Spain, 32 442 from Germany, 25 173 from the UK, 13 270 from France, 5580 from Scotland, 4614 from Hong Kong, and 2322 from Australia. During 2011-21, the combined proportional initiation of the cardioprotective antihyperglycaemic drugs (glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors) increased across all data sources, with the combined initiation of these drugs as second line drugs in 2021 ranging from 35.2% to 68.2% in the US databases, 15.4% in France, 34.7% in Spain, 50.1% in Germany, and 54.8% in Scotland. From 2016 to 2021, in some US and non-US databases, uptake of glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors increased more significantly among populations with no cardiovascular disease compared with patients with established cardiovascular disease. No data source provided evidence of a greater increase in the uptake of these two drug classes in populations with cardiovascular disease compared with no cardiovascular disease.

Conclusions

Despite the increase in overall uptake of cardioprotective antihyperglycaemic drugs as second line treatments for type 2 diabetes mellitus, their uptake was lower in patients with cardiovascular disease than in people with no cardiovascular disease over the past decade. A strategy is needed to ensure that medication use is concordant with guideline recommendations to improve outcomes of patients with type 2 diabetes mellitus.

Euglycemic diabetic ketoacidosis in the era of SGLT-2 inhibitors

Euglycemic diabetic ketoacidosis (EDKA) is an emerging complication of diabetes associated with an increasing use of sodium-glucose transporter type 2 (SGLT-2) inhibitor drugs. This review highlights the growing incidence of EDKA and its diagnostic challenges due to the absence of hallmark hyperglycemia seen in diabetic ketoacidosis (DKA). The paper presents a classification system for the severity of EDKA, categorizing it into mild, moderate, and severe based on serum pH and bicarbonate levels. Another classification system is proposed to define stages of EDKA based on anion gap and ketones at the time of diagnosis and during the treatment period. A treatment algorithm is proposed to guide clinicians in managing EDKA. This treatment algorithm includes monitoring anion gap and ketones to guide insulin and fluid management, and slower transition to subcutaneous insulin to prevent a relapse. Increased awareness of EDKA is essential for a timely diagnosis because an early diagnosis and treatment can improve clinical outcomes.

Baseline modern medical management in the BEST-CLI trial

OBJECTIVES

The use of optimal medical therapy (OMT) in patients with chronic limb-threatening ischemia (CLTI) has not been well-studied. The Best Endovascular vs Best Surgical Therapy in Patients with CLTI study (BEST-CLI) is a multicenter, randomized, controlled trial sponsored by the National Institutes of Health comparing revascularization strategies in patients with CLTI. We evaluated the use of guideline-based OMT among patients with CLTI at the time of their enrollment into the trial.

METHODS

A multidisciplinary committee defined OMT criteria related to blood pressure and diabetic management, lipid-lowering and antiplatelet medication use, and smoking status for patients enrolled in BEST-CLI. Status reports indicating adherence to OMT were provided to participating sites at regular intervals. Baseline demographic characteristics, comorbid medical conditions, and use of OMT at trial entry were evaluated for all randomized patients. A linear regression model was used to identify the relationship of predictors to the use of OMT.

RESULTS

At the time of randomization (n = 1830 total enrolled), 87% of patients in BEST-CLI had hypertension, 69% had diabetes, 73% had hyperlipidemia, and 35% were currently smoking. Adherence to four OMT components (controlled blood pressure, not currently smoking, use of one lipid-lowering medication, and use of an antiplatelet agent) was modest. Only 25% of patients met all four OMT criteria; 38% met three, 24% met two, 11% met only one, and 2% met none. Age ≥80 years, coronary artery disease, diabetes, and Hispanic ethnicity were positively associated, whereas Black race was negatively associated, with the use of OMT.

CONCLUSIONS

A significant proportion of patients in BEST-CLI did not meet OMT guideline-based recommendations at time of entry. These data suggest a persistent major gap in the medical management of patients with advanced peripheral atherosclerosis and CLTI. Changes in OMT adherence over the course of the trial and their impact on clinical outcomes and quality of life will be assessed in future analyses.

Pharmaceuticals in hospital wastewaters: an analysis of the UBA's pharmaceutical database

The presence of pharmaceuticals in hospital wastewaters (HWW) has been a focus of interest for researchers in the last decades. Certain therapeutic classes, such as X-ray contrast media, broad-spectrum antimicrobials and cytotoxics among others, are mainly used in hospitals-health care facilities. This study is focused on available studies monitoring the presence of pharmaceuticals in HWW around the world. To that end, the last available version (v3. 2021) of the "Pharmaceuticals in the Environment" database published by the Federal German Environment Agency (Umweltbundesamt) has been used. Almost half of all studies included (107) have been conducted in Europe. Pharmaceuticals have been monitored in HWW in 38 different countries across all five continents. The country with the greatest number of studies is Brazil (11), followed by Spain (8), China (7), and France (6). Our analysis revealed that 271 different pharmaceuticals have been detected at least once in HWW. The five drugs with more studies showing a positive detection are ciprofloxacin (38), sulfamethoxazole (36), diclofenac (34), ibuprofen (29), and trimethoprim (27). A total of 47 out of 271 drugs are considered in the NIOSH "Hazardous drug" list. However, monitoring data for some widely used drugs in hospital settings such as muscle relaxants, anesthetics, and antidotes is lacking. In conclusion, this study provides the first large-scale metadata analysis for the pharmaceuticals in HWW worldwide.

Trends in use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) in Australia in the era of increased evidence of their cardiovascular benefits (2014-2022)

PURPOSE

To investigate trends in SGLT2i and GLP-1RA use in Australia in the era of increased evidence of their cardiovascular benefits.

METHODS

We used national dispensing claims for a 10% random sample of Australians to estimate the number of prevalent and new users (no dispensing in the prior year) of SGLT2i or GLP-1RA per month from January 2014 to July 2022. We assessed prescriber specialty and prior use of other antidiabetic and cardiovascular medicines as a proxy for evidence of type 2 diabetes (T2D) and cardiovascular conditions, respectively.

RESULTS

We found a large increase in the number of prevalent users (216-fold for SGLT2i; 11-fold for GLP-1RA); in July 2022 approximately 250,000 Australians were dispensed SGLT2i and 120,000 GLP-1RA. Most new users of SGLT2i or GLP-1RA had evidence of both T2D and cardiovascular conditions, although from 2022 onwards, approximately one in five new users of SGLT2i did not have T2D. The proportion of new users initiating SGLT2i by cardiologists increased after 2021, reaching 10.0% of initiations in July 2022. Among new users with evidence of cardiovascular conditions, empagliflozin was the most commonly prescribed SGLT2i, while dulaglutide or semaglutide was the most common GLP-1RA.

CONCLUSION

SGLT2i and GLP-1RA use is increasing in Australia, particularly in populations with higher cardiovascular risk. The increased use of SGLT2i among people without evidence of T2D suggests that best-evidence medicines are adopted in Australia across specialties, aligning with new evidence and expanding indications.

Adoption of sodium-glucose cotransporter-2 inhibitors among prescribers caring for nursing home residents

BACKGROUND

Sodium-glucose cotransporter-2 inhibitor (SGLT2I) use has increased among community-dwelling populations, but little is known about how clinicians have prescribed them for US nursing home (NH) residents. We described the adoption of SGLT2Is by prescribers caring for long-stay NH residents by clinician specialty and over time, compared with sulfonylureas, an older diabetes medication class.

METHODS

We conducted a retrospective cohort study of prescribers of SGLT2Is and sulfonylureas for all long-stay US NH residents aged 65 years or older (2017-2019). Using 100% of Medicare Part D claims linked to prescriber characteristics data, we identified all dispensings of SGLT2Is and sulfonylureas for long-stay NH residents and their associated prescribers. We described the distribution of prescriber specialties for each drug class over time as well as the number of NH residents prescribed SGLT2s versus sulfonylureas. We estimated the proportions of prescribers who prescribed both drug classes versus only sulfonylureas or only SGLT2Is.

RESULTS

We identified 36,427 unique prescribers (SGLT2I: N = 5811; sulfonylureas: N = 35,443) for 117,667 NH residents between 2017 and 2019. For both classes, family medicine and internal medicine physicians accounted for most prescriptions (75%-81%). Most clinicians (87%) prescribed only sulfonylureas, 2% prescribed SGLT2Is only, and 11% prescribed both. Geriatricians were least likely to prescribe only SGLT2Is. We observed an increase in the number of residents with SGLT2I use from n = 2344 in 2017 to n = 5748 in 2019.

CONCLUSIONS

Among NH residents, most clinicians have not incorporated SGLT2Is into their prescribing for diabetes, but the extent of use is increasing. Family medicine and internal medicine physicians prescribed the majority of diabetes medications for NH residents, and geriatricians were the least likely to prescribe only SGLT2Is. Future research should explore provider concerns regarding SGLT2I prescribing, particularly adverse events.

Telehealth Intervention to Improve Uptake of Evidence-Based Medications among Patients with Type 2 Diabetes and Heart Failure or Cardiovascular Disease

INTRODUCTION

Sodium glucose cotransporter-2 (SGLT-2) inhibitors and glucagon-like peptide 1 receptor (GLP-1) agonists are recommended for patients with type two diabetes (T2D) and atherosclerotic cardiovascular disease (ASCVD) or heart failure (HF) to reduce cardiovascular-related mortality. The objective of this study was to evaluate a telehealth targeted medication review (TMR) program to identify patients for uptake of these evidence-based medications.

METHODS

This was an observational descriptive study of a TMR program for Medicare-enrolled, Medication Therapy Management-eligible patients in one insurance plan. Prescription claims and patient interviews identified individuals who would benefit from SGLT-2 inhibitors or GLP-1 agonists. Facsimiles were sent to providers of patients with educational information about the targeted medications. Descriptive statistics described characteristics and proportion of patients prescribed targeted medications after 120 days. Bivariate statistical tests evaluated associations between age, sex, number of medications, number of providers, and poverty level with adoption of targeted medications.

RESULTS

A total of 1106 of 1127 had a facsimile sent to their provider after a conversation with the patient. Among patients with a provider facsimile, 69 (6%) patients filled a prescription for a targeted medication after 120 days. There was a significant difference in age between individuals who started a targeted medication (67 ± 10 years) compared with patients who did not (71 ± 10 years) (p = 0.001).

CONCLUSIONS

A TMR efficiently identified patients with T2D and ASCVD or HF who would benefit from evidence-based medications. Although younger patients were more likely to receive these medications, the overall uptake of these medications within four months of the intervention was lower than expected.

SGLT2 Inhibitors: The Next Blockbuster Multifaceted Drug?

Sodium glucose cotransporter 2 inhibitor (SGLT2i) is a class of drugs that were originally intended for decreasing blood glucose in diabetes. However, recent trials have shown that there are other beneficial effects. Major clinical trials involving SGLT2i medications from 2015 to 2022 were reviewed using PUBMED search. Recent major SGLT2i landmark trials have demonstrated benefits for cardiovascular disease (reduce major adverse cardiovascular events (heart attack, stroke, cardiovascular death), hospitalization for heart failure, all-cause death), and renal disease (delay the onset of dialysis) regardless of diabetic status. The consistent cardiorenal benefits observed in major landmark trials have resulted in the rapid adoption of SGLT2i therapy not only in diabetes guidelines but also cardiovascular and renal guidelines.

Transitioning to GLP-1 RAs and SGLT2 Inhibitors as the First Choice for Managing Cardiometabolic Risk in Type 2 Diabetes

PURPOSE OF REVIEW

This forward-looking review summarizes existing evidence from cardiovascular outcome trials on cardiometabolic risk-reduction in type 2 diabetes (T2DM) management, with attention to updating and personalizing recommendations from recent diabetes practice guidelines issued by cardiology societies.

RECENT FINDINGS

T2DM management has shifted towards cardiometabolic outcome improvement rather than purely glycemic control. According to large clinical trials, sodium-glucose cotransporter-2 inhibitors showed robust results in reducing heart failure (HF) hospitalization and chronic kidney disease (CKD) progression, while glucagon-like peptide-1 receptor agonists demonstrated the largest effects on HbA1c reduction, weight loss, and atherosclerotic cardiovascular disease outcomes prevention, including stroke. Considering the distinct features of these new cardiometabolic agents, initial selection of therapy should be targeted to each individual patient, with consideration of combination therapy for the highest risk patients. Moreover, future studies should investigate the addition of obesity-predominant risk, in conjunction with coronary artery disease, stroke, CKD, and HF, as a new influential indicator for choosing the optimal cardiometabolic agent.

The prescribing pattern of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists in patient with type two diabetes mellitus: A two-center retrospective cross-sectional study

Background

The use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) in patients with type 2 diabetes mellitus (T2DM) remains limited, especially in those with other compelling indications. Thus, this study aimed to describe the prescribing patterns of GLP-1-RA and SGLT2i in patients with T2DM and to determine the factors that affect the prescribing of these medications.

Methods

This multicenter retrospective cross-sectional study reviewed the electronic health records of adult patients diagnosed with T2DM who received care between January and December 2020. The patients were classified according to their compelling indications into "patients who are more likely" to benefit from SGLT2i or GLP-1 RA and "patients who are less likely" to benefit from them. They were then further categorized depending on whether these medications were prescribed.

Results

A total of 1,220 patients were included; most were female (56.9%). SGLT2i or GLP-1 RA were preferably prescribed in only 19% of the patients for reasons including BMI ≥ 27 kg/m² (85.6%), uncontrolled T2DM (68.5%), high risk for ASCVD (23.9%), or established ASCVD (14%). The remaining 81.0% were underprescribed these agents. Patients at an older age or with a history of stroke or transient ischemic attack had higher odds of being underprescribed (OR 1.02; 95% CI: 1.01-1.03 and OR 2.86; 95% CI: 1.33-6.15), respectively.

Conclusion

The results concur with those of previous studies highlighting the underutilization of GLP-1 RA and SGLT2i in patients with T2DM but also with compelling indications. To optimize the use of GLP-1 RA and SGLT2i for their additional benefits, prescribers need to assess the benefits of using these agents in patients who would likely benefit from them, regardless of DM control.

Real-world national trends and socio-economic factors preference of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists in China

Backgrounds

Robust evidence have demonstrated the beneficial effect of Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) in T2D patients with cardiovascular diseases and chronic kidney disease. Multiple studies analyzed patterns and predictors of SGLT2i and GLP-1RA in the US, Europe and worldwide. However, there is no study about the utilization of these two classes of drugs in real-world in China.

Method

A total of 181743 prescriptions of SGLT2i and 59720 GLP-1RA were retrospectively pooled from Hospital Prescription Analysis Cooperation Project from 2018 to 2021. The social-economic characteristics of patients and prescribers, including age, gender, residency, hospital level, insurance type, department visited, and payment amount, were collected and analyzed to study trends and risk factors associated with preference among two antidiabetics.

Results

Annual number of prescriptions of SGLT2i significantly increased to approximately 140 folds, while GLP-1RA increased to about 6.5 folds. After adjustment for socio-economic information, several patients or physician characteristics were positively associated with the preference of GLP-1RA, including female gender (OR 1.581, 95% CI 1.528-1.635), residents in second-tier cities (OR 1.194, 95% CI 1.148-1.142), visiting primary or secondary hospital level (OR 2.387, 95% CI 2.268-2.512); while other factors were associated with the preference of SGLT2i, including older adults (OR 0.713, 95% CI 0.688-0.739), uncovered by insurance (OR 0.310, 95% CI 0.293-0.329), visiting other departments compared with endocrinology. In addition, the share of SGLT2i and GLP-1RA was low but in an increasing tendency.

Conclusions

SGLT2i and GLP-1RA prescription significantly increased from 2018 to 2021. The socio-economic risk factors in choosing SGLT2i or GLP-1RA highlight an effort required to reduce disparities and improve health outcomes.
