Assessing the cardiovascular events and clinical outcomes of COVID-19 on patients with primary aldosteronism

Association of Angiotensin Receptor-Neprilysin Inhibitors Use and Better Cardiorenal Outcomes in Patients With Heart Failure and Acute Kidney Disease

PURPOSE

Angiotensin receptor-neprilysin inhibitors (ARNi) have been shown to improve cardiovascular outcomes in heart failure (HF) patients. However, their impact on HF patients with concurrent acute kidney disease (AKD) remains underexplored. This study investigated the outcomes of ARNi compared to angiotensin-converting enzyme inhibitors (ACEi) in HF patients with AKD.

METHODS

The study included 20,009 hospitalized HF and AKD patients who underwent dialysis during hospitalization, recovered from dialysis within 90 days after discharge, and were followed until November 30, 2022, using data from TriNetX. The study period began in July 2015, coinciding with the availability of ARNi in the market. Propensity score matching (1:1) was applied to balance ARNi and ACEi groups. Adjusted hazard ratios (aHR) with 95% confidence intervals (CI) were calculated to assess the risks of mortality, major adverse kidney events (MAKE), readmission and major adverse cardiac events (MACE). The follow-up period was conducted with a maximum duration of 5 years.

RESULTS

A total of 20,009 AKD patients (mean [SD] age, 59.1 [12.2] years) were enrolled, of whom 21.9% received ARNi, with a median follow-up of 2.3 years. After matching, 4391 patients (mean age, 58.6 years; male, 67.9%) were identified in both the ARNi and control groups. ARNi users exhibited a significantly lower risk of mortality (aHR, 0.32, 95% CI 0.13-0.80, p = 0.01), MAKE (aHR, 0.58, 95% CI 0.51-0.66, p < 0.01 ), and readmission (aHR, 0.61, 95% CI 0.55-0.68, p <0.01) versus controls. However, no significant difference in the risk of MACE was observed between the two groups (aHR, 0.94, 95% CI 0.82-1.09, p = 0.78). Subgroup analysis revealed ARNi users, when concomitantly treated with mineralocorticoids, diuretics, or beta-blockers had significantly lower risks of mortality, readmission, and MAKE than the control group. In addition, ARNi significantly reduced mortality and MAKE in patients with GFR 30-60 mL/min/1.73 m2, irrespective of proteinuria status. However, no significant benefit was observed in patients with GFR <30 mL/min/1.73 m2.

CONCLUSIONS

In HF patients with AKD, ARNi was associated with reduced all-cause mortality, MAKE, and readmission risks compared to ACEi, particularly with concurrent mineralocorticoids, diuretics, or beta-blockers. Future research is necessary to further investigate the impact of ARNi on outcomes in patients with HF and AKD.

Association of glucagon-like peptide-1 receptor agonists with cardiovascular and kidney outcomes in type 2 diabetic kidney transplant recipients

BACKGROUND

Cardiovascular disease is a leading cause of post-transplant mortality in kidney transplant recipients (KTRs), especially those with diabetes. Although glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated cardiovascular and kidney benefits in the general population with type 2 diabetes mellitus (T2DM), evidence regarding their effects in diabetic KTRs is limited.

METHODS

This retrospective cohort study utilized data from the Global Collaborative Network in TriNetX, spanning January 1, 2006, to June 1, 2023. Propensity score matching (PSM) with 1:1 ratio was employed to create balanced cohorts. Adult KTRs with T2DM who received GLP-1 RAs within 3 months post-transplant were compared to a matched cohort of KTRs who did not. The primary outcome was all-cause mortality, with secondary outcomes including major adverse cardiovascular events (MACEs) and major adverse kidney events (MAKEs).

RESULTS

A total of 35,488 adult KTRs with T2DM (mean [SD] age, 57.7 [12.2] years; 57.7% men) were identified and 9.8% patients used GLP-1 RAs among 3 months post-transplant. Following PSM, 3564 GLP-1 RAs users were matched with an equal number of nonusers. After a median follow-up of 2.5 years, GLP-1 RAs users had lower risks of mortality (adjusted hazard ratio (aHR), 0.39; 95% CI 0.31-0.50), MACEs (aHR 0.66; 95% CI 0.56-0.79), and MAKEs (aHR 0.66; 95% CI 0.58-0.75). Adverse effects included higher risks of nausea, vomiting and diarrhea, while risks of suicide, hypoglycemia, retinopathy, and pancreatitis were not increased.

CONCLUSIONS

In KTRs with T2DM, GLP-1 RAs use was associated with substantial reductions in all-cause mortality, MAKEs, and MACEs compared to nonuse without increasing complications. However, the underutilization of GLP-1 RAs represents a significant opportunity to improve post-transplant outcomes in this high-risk population.

Dipeptidyl peptidase 4 inhibitors reduce the risk of adverse outcomes after acute kidney injury in diabetic patients

Background

Dipeptidyl peptidase 4 inhibitors (DPP4is) are considered safe for use in patients with diabetes mellitus and kidney dysfunction. We explored whether usage of DPP4is in patients who recovered from dialysis-requiring acute kidney injury (AKI) could reduce the risk of future cardiac and kidney events.

Methods

We used the TriNetX platform to investigate whether the use of DPP4is in diabetes mellitus patients within 90 days of discharge from acute kidney disease could reduce the risk of all-cause mortality, major adverse kidney events (MAKEs), major adverse cardiovascular events (MACEs), and re-dialysis. The patients were followed for 5 years or until the occurrence of significant outcomes, with cohort data collected from 1 January 2016 to 30 September 2022.

Results

The cohort utilizing DPP4is comprised 7348 patients with acute kidney disease, while the control group encompassed 229 417 individuals. After applying propensity score matching, 7343 patients (age 66.2 ± 13.4 years; male, 49.9%) who used DPP4is showed a significant reduction in the risk of all-cause mortality [adjusted hazard ratio (aHR) 0.89; E-value 1.50 , MAKEs (aHR 0.86; E-value 1.59), MACEs (aHR 0.91; E-value 1.44), and re-dialysis (aHR 0.73; E-value 2.10) after a median follow-up of 2.4 years.

Conclusions

We demonstrated that in diabetes mellitus patients concurrently experiencing acute kidney disease, DPP4i usage could decrease the risk of mortality, MAKEs, MACEs, and re-dialysis. These findings emphasize the pivotal role of tailored treatment strategies involving DPP4i for acute kidney disease patients.

Exploring the mortality and cardiovascular outcomes with SGLT-2 inhibitors in patients with T2DM at dialysis commencement: a health global federated network analysis

BACKGROUND

Sodium-glucose cotransporter 2 inhibitors (SGLT-2is) have demonstrated associations with lowering cardiovascular outcomes in patients with type 2 diabetes mellitus (T2DM). However, the impact of SGLT-2is on individuals at dialysis commencement remains unclear. The aim of this real-world study is to study the association between SGLT-2is and outcomes in patients with T2DM at dialysis commencement.

METHODS

This is a retrospective cohort study of electronic health records (EHRs) of patients with T2DM from TriNetX Research Network database between January 1, 2012, and January 1, 2024. New-users using intention to treatment design was employed and propensity score matching was utilized to select the cohort. Clinical outcomes included major adverse cardiac events (MACE) and all-cause mortality. Safety outcomes using ICD-10 codes, ketoacidosis, urinary tract infection (UTI) or genital infection, dehydration, bone fracture, below-knee amputation, hypoglycemia, and achieving dialysis-free status at 90 days and 90-day readmission.

RESULTS

Of 49,762 patients with T2DM who initiated dialysis for evaluation, a mere 1.57% of patients utilized SGLT-2is within 3 months after dialysis. 771 SGLT-2i users (age 63.3 ± 12.3 years, male 65.1%) were matched with 771 non-users (age 63.1 ± 12.9 years, male 65.8%). After a median follow-up of 2.0 (IQR 0.3-3.9) years, SGLT-2i users were associated with a lower risk of MACE (adjusted Hazard Ratio [aHR] = 0.52, p value < 0.001), all-cause mortality (aHR = 0.49, p < 0.001). SGLT-2i users were more likely to become dialysis-free 90 days after the index date (aHR = 0.49, p < 0.001). No significant differences were observed in the incidence of ketoacidosis, UTI or genital infection, hypoglycemia, dehydration, bone fractures, below-knee amputations, or 90-day readmissions.

CONCLUSIONS

Our findings indicated a lower incidence of all-cause mortality and MACE after long-term follow-up, along with a higher likelihood of achieving dialysis-free status at 90 days in SGLT-2i users. Importantly, they underscored the potential cardiovascular protection and safety of SGLT-2is use in T2DM patients at the onset of dialysis.

Mortality and cardiovascular events in diabetes mellitus patients at dialysis initiation treated with glucagon-like peptide-1 receptor agonists

BACKGROUND

Glucagon-like Peptide-1 Receptor Agonists (GLP-1RAs) have demonstrated efficacy in improving mortality and cardiovascular (CV) outcomes. However, the impact of GLP-1RAs therapy on cardiorenal outcomes of diabetic patients at the commencement of dialysis remains unexplored.

PURPOSE

This study aimed to investigate the long-term benefits of GLP-1RAs in type 2 diabetic patients at dialysis commencement.

METHODS

A cohort of type 2 diabetic patients initializing dialysis was identified from the TriNetX global database. Patients treated with GLP-1RAs and those treated with long-acting insulin (LAI) were matched by propensity score. We focused on all-cause mortality, four-point major adverse cardiovascular events (4p-MACE), and major adverse kidney events (MAKE).

RESULTS

Among 82,041 type 2 diabetic patients initializing dialysis, 2.1% (n = 1685) patients were GLP-1RAs users (mean ages 59.3 years; 55.4% male). 1682 patients were included in the propensity-matched group, treated either with GLP-1RAs or LAI. The main causes of acute dialysis in this study were ischemic heart disease (17.2%), followed by heart failure (13.6%) and sepsis (6.5%). Following a median follow-up of 1.4 years, GLP-1RAs uses at dialysis commencement was associated with a reduced risk of mortality (hazard ratio [HR] = 0.63, p < 0.001), 4p-MACE (HR = 0.65, p < 0.001), and MAKE (HR = 0.75, p < 0.001). This association was particularly notable in long-acting GLP-1RAs users, with higher BMI, lower HbA1c, and those with eGFR > 15 ml/min/1.73m2. GLP-1RAs' new use at dialysis commencement was significantly associated with a lower risk of MACE (p = 0.047) and MAKE (p = 0.004). Additionally, GLP-1RAs use among those who could discontinue from acute dialysis or long-term RAs users was associated with a lower risk of mortality, 4p-MACE, and MAKE.

CONCLUSION

Given to the limitations of this observational study, use of GLP-1RAs at the onset of dialysis was associated with a decreased risk of MACE, MAKE, and all-cause mortality. These findings show the lack of harm associated with the use of GLP-1RAs in diabetic patients at the initiation of acute dialysis.

GLP-1 receptor agonists' impact on cardio-renal outcomes and mortality in T2D with acute kidney disease

Previous studies have explored the effects of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in reducing cardiovascular events in type 2 diabetes. Here we show that GLP-1 RAs are associated with lower risks of mortality, major cardiovascular events (MACEs), and major adverse kidney events (MAKEs) in type 2 diabetes patients with acute kidney disease (AKD). Utilizing global data from the TriNetX database (2002/09/01-2022/12/01) and propensity score matching, we compare 7511 GLP-1 RAs users to non-users among 165,860 AKD patients. The most common causes of AKI are sepsis (55.2%) and cardiorenal syndrome (34.2%). After a median follow-up of 2.3 years, GLP-1 RAs users exhibit reduced risks of mortality (adjusted hazard ratio [aHR]: 0.57), MACEs (aHR: 0.88), and MAKEs (aHR: 0.73). External validation in a multicenter dataset of 1245 type 2 diabetes patients with AKD supports the favorable outcomes. These results emphasize the potential of GLP-1 RAs in individualized treatment for this population.

Sodium-Glucose Cotransport Protein 2 Inhibitors in Patients With Type 2 Diabetes and Acute Kidney Disease

Importance

Sodium-glucose cotransport protein 2 inhibitors (SGLT-2is) have demonstrated associations with positive kidney-related and cardiovascular outcomes in patients with type 2 diabetes. However, the association of SGLT-2is with outcomes among patients with type 2 diabetes and acute kidney disease (AKD) remains unclear.

Objective

To examine the long-term associations of SGLT-2is with mortality, major adverse kidney events (MAKEs), and major adverse cardiovascular events (MACEs) in patients with type 2 diabetes and AKD.

Design, Setting, and Participants

This cohort study used global health care data (the TriNetX database) spanning from September 30, 2002, to September 30, 2022. Propensity score matching was used to select a cohort of patients, and follow-up was conducted with a maximum duration of 5 years (completed on September 30, 2022) or until the occurrence of an outcome or death.

Intervention

The use of SGLT-2is.

Main Outcomes and Measures

The primary outcomes measured were mortality, MAKEs, and MACEs. Adjusted hazard ratios (AHR) with 95% CIs were calculated to compare the risks between SGLT-2i users and nonusers, representing the mean treatment effect among the treated patients.

Results

A total of 230 366 patients with AKD (mean [SD] age, 67.1 [16.4] years; 51.8% men and 48.2% women) were enrolled in the study, which had a median follow-up duration of 2.3 (IQR, 1.2-3.5) years. Among these, 5319 individuals (2.3%) were identified as SGLT-2i users. Among nonusers, the incidence of mortality was 18.7%, the incidence of MAKEs was 21.0%, and the incidence of MACEs was 25.8%. After propensity score matching, the absolute differences between SGLT-2i users and nonusers for incidence of mortality, MAKEs, and MACEs were 9.7%, 11.5%, and 12.3%, respectively. Based on the treated population, SGLT-2i use was associated with a significantly lower risk of mortality (AHR, 0.69 [95% CI, 0.62-0.77]), MAKEs (AHR, 0.62 [95% CI, 0.56-0.69]), and MACEs (AHR, 0.75 [95% CI, 0.65-0.88]) compared with nonuse. External validation using a multicenter cohort data set of 1233 patients with AKD patients who were SGLT-2i users confirmed the observed beneficial outcomes. Notably, the risk reduction associated with SGLT-2is remained significant even among patients without hypertension, those with advanced chronic kidney disease, and those not receiving other hypoglycemic agents.

Conclusions and Relevance

In this cohort study of patients with type 2 diabetes and AKD, administration of SGLT-2is was associated with a significant reduction in all-cause mortality, MAKEs, and MACEs when compared with nonuse, underscoring the importance of SGLT-2is in care after acute kidney injury. These findings emphasize the potential benefits of SGLT-2is in managing AKD and mitigating the risks of major cardiovascular and kidney diseases.
