- <b><i>Background:</i></b> Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that 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 CV and renal outcomes has not yet been investigated in long-term trials. <b><i>Patients and</i></b> <b><i>Methods:</i></b> The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate ≥25 mL/min/1.73 m<sup>2</sup> and albuminuria (urinary albumin-to-creatinine ratio ≥30 to ≤5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level α = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. <b><i>Conclusions:</i></b> FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen. Trial Registration: EudraCT number: 2015-000950-39; ClinicalTrials.gov identifier: NCT02545049.

- Angiotensin II ( Ang II) is the major vasoactive component of the renin- angiotensin system. Several components of the renin- angiotensin system have been demonstrated in different tissues. Whereas the roles of tissue and renal renin- angiotensin system have been studied in detail, much less is known on whether the corpuscular elements of circulating blood contribute to Ang II production. Here we examined whether, in addition to vasculature, blood cells also contribute to the circulating Ang II levels. Mononuclear leukocytes were obtained from healthy subjects and were incubated. The resulting supernatant was chromatographed using different chromatographic methods. The vasoconstrictive effects of aliquots of the resulting fractions were tested. Each fraction with a vasoconstrictive effect was analyzed by mass spectrometry. In one fraction with a strong vasoconstrictive effect, Ang II was identified. Mononuclear lymphocytes produced Ang II in amounts sufficient to stimulate Ang II type 1 receptors. Moreover, in mononuclear leukocytes, renin as well as angiotensin- converting enzyme mRNA expression was detectable by RT- PCR. These findings demonstrate that mononuclear leukocytes are a source of Ang II. Ang II secretion by these cells may play a significant role in humoral vascular regulation. In conclusion, the isolation of Ang II in supernatants of mononuclear leukocytes adds a further physiological source of Ang II to the current view of angiotensin metabolism. The quantitative role of lymphocyte- derived Ang II secretion compared with the other sources of Ang II should be defined further, but the release found under the present conditions is at least sufficient to elicit vasoconstrictive effects

- The acute phase protein group IIA secretory phospholipase A2 (sPLA2-IIA) has intrinsic proatherosclerotic properties. The present prospective cohort study investigated whether plasma sPLA2-IIA associates with graft failure, cardiovascular, and all-cause mortality in renal transplant recipients (RTRs), patients with accelerated atherosclerosis formation both systemically and within the graft. In 511 RTRs from a single academic center with stable graft function >1 year, baseline plasma sPLA2-IIA was determined by ELISA. Primary end points were death-censored graft failure and mortality (median follow-up, 7.0 years). Baseline sPLA2-IIA was higher in RTRs than in healthy controls (median 384 ng/dL (range 86–6951) vs. 185 ng/dL (range 104–271), p < 0.001). Kaplan–Meier analysis demonstrated increased risk for graft failure (p = 0.002), as well as cardiovascular (p < 0.001) and all-cause mortality (p < 0.001), with increasing sPLA2-IIA quartiles. Cox regression showed strong associations of sPLA2-IIA with increased risks of graft failure (hazard ratio (HR) = 1.42 (1.11–1.83), p = 0.006), as well as cardiovascular (HR = 1.48 (1.18−1.85), p = 0.001) and all-cause mortality (HR = 1.39 (1.17−1.64), p < 0.001), dependent on parameters of kidney function. Renal function during follow-up declined faster in RTRs with higher baseline sPLA2-IIA levels. In RTRs, sPLA2-IIA is a significant predictive biomarker for chronic graft failure, as well as overall and cardiovascular disease mortality dependent on kidney function. This dependency is conceivably explained by sPLA2-IIA impacting negatively on kidney function.
