Lessons from the Trials for the Desirable Effects of Sodium Glucose Co-Transporter 2 Inhibitors on Diabetic Cardiovascular Events and Renal Dysfunction.

ABSTRACT: Recent large placebo-controlled trials of sodium glucose co-transporter 2 (SGLT2) inhibitors revealed desirable effects on heart failure (HF) and renal dysfunction; however, the mechanisms underlying these effects are unknown. The characteristic changes in the early stage of diabetic cardiomyopathy (DCM) are myocardial and interstitial fibrosis, resulting in diastolic and subsequent systolic dysfunction, which leads to clinical HF. Pericytes are considered to play crucial roles in myocardial and interstitial fibrosis. In both DCM and diabetic retinopathy (DR), microaneurysm formation and a decrease in capillaries occur, triggered by pericyte loss. Furthermore, tubulointerstitial fibrosis develops in early diabetic nephropathy (DN), in which pericytes and mesangial cells are thought to play important roles. Previous reports indicate that pericytes and mesangial cells play key roles in the pathogenesis of DCM, DR and DN. SGLT2 is reported to be functionally expressed in pericytes and mesangial cells, and excessive glucose and Na+ entry through SGLT2 causes cellular dysfunction in a diabetic state. Since SGLT2 inhibitors can attenuate the high glucose-induced dysfunction of pericytes and mesangial cells, the desirable effects of SGLT2 inhibitors on HF and renal dysfunction might be explained by their direct actions on these cells in the heart and kidney microvasculature.

Project description:BackgroundThe clinical benefit of sodium-glucose cotransporter 2 (SGLT2) inhibitors for preventing and treating cardiovascular events remains controversial. We aimed to study the effect of SGLT2 inhibitors on cardiovascular outcomes and safety events, giving particular attention to the benefits in subgroups of patients with different diseases.MethodRandomized controlled trials (RCTs) reporting cardiovascular outcomes following the administration of SGLT2 inhibitors and placebo were included in this study. Cardiovascular outcomes included all-cause death, major adverse cardiovascular events (MACEs), cardiovascular (CV) death, myocardial infarction (MI), stroke, and hospitalization for heart failure (HHF). We also focused on the cardiovascular benefits of SGLT2 inhibitor application in subgroups of patients with different diseases, including type 2 diabetes (T2D), heart failure (HF), high risk of atherosclerotic cardiovascular disease (ACD), diagnosed ACD, and chronic kidney disease (CKD). Safety events associated with SGLT2 inhibitors, including acute kidney injury (AKI), diabetic ketoacidosis (DKA), hypoglycemia, urinary tract infection, thromboembolic event, bone fracture, volume depletion, and amputation, were also reported.ResultsThis meta-analysis included 15 RCTs with 78,212 participants. SGLT2 inhibitors reduced the risk of all-cause death (RR 0.89; 95% CI: 0.85-0.94; I2 = 32%; p < 0.01), CV death (RR 0.87; 95% CI: 0.82-0.93; I2 = 11%; p < 0.01), MACEs (RR 0.89; 95% CI: 0.84-0.94; I2 = 46%; p < 0.01), HHF (RR 0.70; 95% CI: 0.66-0.74; I2 = 0%; p < 0.01), and AKI (RR 0.81; 95% CI: 0.73-0.90; I2 = 0%; p < 0.01) but increased the risk of DKA (RR 2.56; 95% CI: 1.72-3.80; I2 = 0%; p < 0.01). However, no apparent benefit in MI and stroke was observed between the SGLT2 inhibitor and control groups. SGLT2 inhibitors reduced the risk of all-cause death, MACEs, CV death, and HHF in diabetic patients; reduced the risk of all-cause death, MACEs, CV death, MI, and HHF in primary prevention; reduced the risk of all-cause death, CV death, and HHF in patients with ACD and HF; and reduced the risk of MACEs, CV death, and HHF in patients with CKD.ConclusionSGLT2 inhibitors have a positive effect in reducing the risk of all-cause death, CV death, MACE, HHF, and AKI and increasing the risk of DKA. The application of SGLT2 inhibitors in the primary prevention of ACD also has certain clinical benefits in reducing MI.Systematic review registration[https://www.crd.york.ac.uk/prospero/], identifier [CRD42022306490].

Project description:Background: Whereas the cardiovascular safety of sodium-glucose co-transporter 2 (SGLT2) inhibitors has been well reported, there is limited data from controlled clinical trials regarding the non-cardiovascular safety. This was the focus of our study. Methods and Findings: We systematically searched MEDLINE, EMBASE, and Cochrane Library (5th Sep 2018) for randomized controlled trials (RCTs) that reported safety data for SGLT2 inhibitors and placebo. Relative risks (RRs) and their 95% confidence intervals (CIs) were pooled using random-effects models. Seventy RCTs (83 studies enrolling 36,958 patients in 78 publications) were identified. SGLT2 inhibitors were associated with a lower risk of serious adverse events (RR 0.90, 95% CI 0.86 to 0.94, P < 0.001), death (RR 0.78, 95% CI 0.64 to 0.94, P < 0.05), gastroenteritis (RR 0.38, 95% CI 0.20 to 0.72, P < 0.05), arthralgia (RR 0.72, 95% CI 0.54 to 0.96, P < 0.05), hypertension (RR 0.61, 95% CI 0.50 to 0.75, P < 0.001), and edema/peripheral edema (RR 0.49, 95% CI 0.33 to 0.72, P < 0.001) compared to placebo. SGLT2 inhibitors were associated with higher risk of infections compared to placebo (RR 1.27, 95% CI 1.17 to 1.37, P < 0.001), especially for genital mycotic infection (GMI) (RR 3.71, 95% CI 3.19 to 4.32, P < 0.001). Other significant effects were observed for osmotic diuresis-related AEs (RR 2.73, 95% CI 2.20 to 3.40, P < 0.001), volume-related AEs (RR 1.26, 95% CI 1.08 to 1.46, P < 0.05), renal-related AEs (RR 1.36, 95% CI 1.02 to 1.80, P < 0.05), hypoglycemia (RR 1.18, 95% CI 1.10 to 1.26, P < 0.001), and increased blood ketone bodies (RR 2.00, 95% CI 1.01 to 3.97, P < 0.05). Subgroup and sensitivity analyses strengthened the robustness of primary results. Conclusion: Results from RCTs confirmed lower risk of death, serious adverse events, hypertension, and edema associated with type 2 diabetes mellitus (T2DM) patients treated with SGLT2 inhibitors when compared with placebo. The use of SGLT2 inhibitors were associated with higher risk of infection, osmotic diuresis, volume depletion effects, renal related AEs, and higher blood ketone bodies when compared with placebo.
