Introduction: Although small-sample size studies have shown that basal alterations of estimated glomerular filtration rate (eGFR) are related to short- and mid-term higher mortality in acute heart failure (AHF), there is scarce information on the influence of an altered eGFR on long-term mortality and readmissions. Therefore, this multicenter study sought to investigate the relationship between eGFR on admission for AHF and both long-term mortality and readmissions in a large sample of patients. Methods: We retrospectively evaluated 4,595 patients consecutively discharged after admission for AHF at three tertiary-care hospitals from January 1, 2008, to January 1, 2020. To investigate the effect of eGFR on admission with long-term morbimortality, we stratified the patients according to four eGFR categories: <30 mL·min−1·1.73 m−2 (G4 and G5 patients, n = 534), 30–44 mL·min−1·1.73 m−2 (G3b patients, n = 882), 45–59 mL·min−1·1.73 m−2 (G3a patients, n = 1,080), and ≥60 mL·min−1·1.73 m−2 (G1 and G2 patients, n = 2,099). eGFR was calculated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation within the first 24 h following admission. Results: At a median follow-up of 2.20 years, multivariate analyses revealed that compared to G1 and G2 patients, G4 and G5 patients exhibited a higher risk of all-cause (HR = 1.15, 95% CI: 01.02–1.30, p = 0.020) and cardiovascular (CV) (HR = 1.20, 95% CI: 1.04–1.39, p = 0.013) mortality. Similarly, multivariate analyses also showed that the lower the eGFR, the higher the risk of readmissions. In fact, compared to G1 and G2 patients, G4 and G5 patients displayed significantly increased incident rate ratios of total all-cause (28%), CV (26%), and HF-related (30%) readmissions. Conclusion: Data from this large study provide evidence that an eGFR below 30 mL·min−1·1.73 m−2 on admission could be an independent predictor for long-term mortality and readmissions in patients with AHF.

Type 2 diabetes mellitus (T2DM) affects an estimated 463 million people worldwide, equivalent to 1 in 11 adults. Moreover, the rapid growth of this disease has resulted in a high incidence of diabetic kidney disease (DKD), which, together with hypertension, is the main cause of chronic kidney disease (CKD). Hyperglycaemia, low-grade inflammation, altered lipid metabolism and hyperactivation of the renin–angiotensin–aldosterone system (RAAS) seem to be interrelated mechanisms contributing to both T2DM and microvascular complications. The introduction of drugs such as sodium–glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists has improved the ability to slow the progression of DKD, and has also demonstrated benefits in cardiovascular disease. Beyond the effects of these novel antidiabetic drugs, a body of evidence suggests that the overactivation of the mineralocorticoid receptor also contributes to CKD progression. Moreover, new and ongoing trials have demonstrated that the selective nonsteroidal mineralocorticoid receptor antagonist (MRA) finerenone improves the risk of CKD progression and cardiovascular events in patients with CKD and T2DM and optimized RAAS blockade. We review the rationale for the development and use of MRA drugs to slow CKD progression in patients with DKD, as well as other pleiotropic effects, and highlight the warnings associated with these agents.

Background. Over the last few years, the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide 1 receptor agonists (GLP-1RA) has increased substantially in medical practice due to their documented benefits in cardiorenal and metabolic health. In this sense, and in addition to being used for glycemic control in diabetic patients, these drugs also have other favorable effects such as weight loss and lowering blood pressure, and more recently, they have been shown to have cardio and renoprotective effects with anti-inflammatory properties. Concerning the latter, the individual or associated use of these antihyperglycemic agents has been linked with a decrease in proinflammatory cytokines and with an improvement in the inflammatory profile in chronic endocrine-metabolic diseases. Hence, these drugs have been positioned as first-line therapy in the management of diabetes and its multiple comorbidities, such as obesity, which has been associated with persistent inflammatory states that induce dysfunction of the adipose tissue. Moreover, other frequent comorbidities in long-standing diabetic patients are chronic complications such as diabetic kidney disease, whose progression can be slowed by SGLT2i and/or GLP-1RA. The neuroendocrine and immunometabolism mechanisms underlying adipose tissue inflammation in individuals with diabetes and cardiometabolic and renal diseases are complex and not fully understood. Summary. This review intends to expose the probable molecular mechanisms and compile evidence of the synergistic or additive anti-inflammatory effects of SGLT2i and GLP-1RA and their potential impact on the management of patients with obesity and cardiorenal compromise.
