Abstract Diabetic kidney disease develops in about 40% of patients with diabetes and is the commonest cause of chronic kidney disease worldwide. Patients with chronic kidney disease, especially those with diabetes mellitus, are at high risk of both developing kidney failure and cardiovascular death. The use of renin-angiotensin system blockers to reduce the incidence of kidney failure in patients with diabetic kidney disease dates back to studies that are now 20 or more years old. During the last few years sodium-glucose co-transporter-2 inhibitors have shown beneficial renal effects in randomized trials. However, even in response to combined treatment with renin-angiotensin system blockers and sodium-glucose co-transporter-2 inhibitors, the renal residual risk remains high with kidney failure only deferred, but not avoided. The risk of cardiovascular death also remains high even with optimal current treatment. Steroidal mineralocorticoid receptor antagonists reduce albuminuria and surrogate markers of cardiovascular disease in patients already on optimal therapy. However, their use has been curtailed by the significant risk of hyperkalaemia. In The FInerenone in reducing kiDnEy faiLure and dIsease prOgression in Diabetic Kidney Disease (FIDELIO-DKD) study comparing the actions of the non-steroidal mineralocorticoid receptor antagonist finerenone with placebo, finerenone reduced the progression of diabetic kidney disease and the incidence of cardiovascular events with a relatively safe adverse event profile. This document presents in detail the available evidence on the cardioprotective and nephroprotective effects of mineralocorticoid receptor antagonists, analyses the potential mechanisms involved and discusses their potential future place in the treatment of patients with diabetic chronic kidney disease.

Diabetic kidney disease and its comorbid conditions, including atherosclerotic cardiovascular disease, heart failure, diabetes, and obesity, are interconnected conditions that compound the risk of kidney failure and cardiovascular mortality, and exponentiate health care costs. Sodium glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide 1 receptor agonist (GLP-1 RA) are novel diabetes medications that prevent cardiovascular events and kidney failure. Clinical trials exploring the cardiovascular and kidney outcomes of SGLT2i and GLP-1 RA have fundamentally shifted the treatment paradigm of diabetes. Clinical guidelines for diabetes management recommend a more holistic approach beyond glycemic control and emphasize heart and kidney protection of SGLT2i and GLP-1 RA. However, the adoption of prescribing SGLT2i and GLP-1 RA for patients with diabetes and high cardiovascular and kidney risk has been slow. In this review, we provide a decision-making tool to help clinicians determine when to consider SGLT2i and GLP-1 RA for heart and kidney protection. First, we discuss a comprehensive risk assessment for patients with diabetic kidney disease. We compare the effectiveness of SGLT2i and GLP-1 RA for different risk categories. Then, we present a decision algorithm using cardiovascular and kidney failure risk stratification and the strength of current evidence for the use of SGLT2i and GLP-1 RA. Lastly, we review the adverse effects of SGLT2i and GLP-1 RA and propose mitigation strategies.

Abstract Background and aims: Diabetic kidney disease (DKD) is associated with lipid derangements worsening kidney function and enhancing cardiovascular (CVD) risk. The management of dyslipidemia, hypertension and other traditional risk factors does not completely prevent CVD complications bringing up the participation of untraditional risk factors such as advanced glycation end products (AGEs), carbamoylation and changes in HDL proteome and functionality. We analyzed HDL composition, proteome, chemical modification and functionality in non-dialytic DKD subjects categorized according to estimated glomerular filtration rate (eGFR) and urinary albumin excretion rate (AER). Methods: DKD individuals were divided in eGFR>60 mL/min/1.73 m2 plus AER stages A1 and A2 (n=10) and eGFR<60 plus A3 (n=25) and matched by age with control subjects (eGFR>60; n=8). Results: Targeted proteomic analyses quantified 28 proteins associated with HDL in all groups, although only 2 were more expressed in eGFR<60+A3 group in comparison to controls: apolipoprotein D (apoD) and apoA-IV. HDL from eGFR<60+A3 presented higher levels of total AGEs (20%), pentosidine (6.3%) and carbamoylation (4.2 x) and a reduced ability in removing 14C-cholesterol from macrophages (33%) in comparison to controls. The antioxidant role of HDL (lag time for LDL oxidation) was similar among groups but HDL from eGFR<60+A3 presented a higher ability in inhibiting the secretion of IL6 and TNF alpha (95%) in LPS-elicited macrophages in comparison to control group. Conclusion: The increment in ApoD and ApoA-IV seems to counteract the HDL chemical modification by AGE and carbamoylation that contributes for HDL loss of function in well-established DKD.

Abstract Despite the standard of care, patients with chronic kidney disease (CKD) and type 2 diabetes (T2D) progress to dialysis, are hospitalized for heart failure and die prematurely. Overactivation of the mineralocorticoid receptor (MR) causes inflammation and fibrosis that damages the kidney and heart. Finerenone, a nonsteroidal, selective MR antagonist, confers kidney and heart protection in both animal models and Phase II clinical studies; the effects on serum potassium and kidney function are minimal. Comprising the largest CKD outcomes program to date, FIDELIO-DKD (FInerenone in reducing kiDnEy faiLure and dIsease prOgression in Diabetic Kidney Disease) and FIGARO-DKD (FInerenone in reducinG cArdiovascular moRtality and mOrbidity in Diabetic Kidney Disease) are Phase III trials investigating the efficacy and safety of finerenone on kidney failure and cardiovascular outcomes from early to advanced CKD in T2D. By including echocardiograms and biomarkers, they extend our understanding of pathophysiology; by including quality of life measurements, they provide patient-centered outcomes; and by including understudied yet high-risk cardiorenal subpopulations, they have the potential to widen the scope of therapy in T2D with CKD. Trial registration number: FIDELIO-DKD (NCT02540993) and FIGARO-DKD (NCT02545049)

The HDL composition, proteome, chemical modification and functionality were analyzed in nondialysis subjects with DKD categorized according to the estimated glomerular filtration rate (eGFR) and urinary albumin excretion rate (AER). Methods Individuals with DKD were divided into eGFR> 60 mL/min/1.73 m2 plus AER stages A1 and A2 (n = 10) and eGFR< 60 plus A3 (n = 25) and matched by age with control subjects (eGFR> 60; n = 8). Results Targeted proteomic analyses quantified 28 proteins associated with HDL in all groups, although only 2 were more highly expressed in the eGFR< 60 + A3 group than in the controls: apolipoprotein D (apoD) and apoA-IV. HDL from the eGFR< 60 + A3 group presented higher levels of total AGEs (20%), pentosidine (6.3%) and carbamoylation (4.2 x) and a reduced ability to remove 14C-cholesterol from macrophages (33%) in comparison to HDL from controls. The antioxidant role of HDL (lag time for LDL oxidation) was similar among groups, but HDL from the eGFR< 60 + A3 group presented a greater ability to inhibit the secretion of IL-6 and TNF-alpha (95%) in LPS-elicited macrophages in comparison to the control group. Conclusion The increase in apoD and apoA-IV could contribute to counteracting the HDL chemical modification by AGEs and carbamoylation, which contributes to HDL loss of function in well-established DKD.

Background: Among diabetics, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality, and progression of their underlying disease. Finerenone is a novel, non-steroidal, selective mineralocorticoid-receptor antagonist which has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD), while revealing only a low risk of hyperkalemia. However, the effect of finerenone on renal and CV outcomes has not been investigated in long-term trials yet. Methods: The Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease ­(FIDELIO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important renal and CV outcomes in T2D patients with CKD. FIDELIO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 5.5 years. FIDELIO-DKD randomized 5,734 patients with an estimated glomerular filtration rate (eGFR) ≥25–<75 mL/min/1.73 m2 and albuminuria (urinary albumin-to-creatinine ratio ≥30–≤5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of primary outcome (overall two-sided significance level α = 0.05), the composite of time to first occurrence of kidney failure, a sustained decrease of eGFR ≥40% from baseline over at least 4 weeks, or renal death. Conclusion: FIDELIO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of renal and CV events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
