The author analyzes the applicability of the renin-angiotensin system blocking drugs in patients with chronic kidney disease emphasizing their renoprotective (blood pressure and albuminuria lowering) and cardiovascular risk decreasing effects. As opposed to a previously-published statement, the author believes that their application is fundamental, particularly in combination with calcium-antagonist drugs. Relying on many references the author suggests that combined treatment with different renin-angiotensin system blocking drugs cannot be entirely ruled out, although it is not yet recommended. Orv.

Abstract Background Acidosis-induced kidney injury is mediated by the intrarenal renin-angiotensin system, for which urinary renin is a potential marker. Therefore, we hypothesized that sodium bicarbonate supplementation reduces urinary renin excretion in patients with chronic kidney disease (CKD) and metabolic acidosis. Methods Patients with CKD stage G4 and plasma bicarbonate 15–24 mmol/l were randomized to receive sodium bicarbonate (3 × 1000 mg/day, ~ 0.5 mEq/kg), sodium chloride (2 × 1,00 mg/day), or no treatment for 4 weeks (n = 15/arm). The effects on urinary renin excretion (primary outcome), other plasma and urine parameters of the renin-angiotensin system, endothelin-1, and proteinuria were analyzed. Results Forty-five patients were included (62 ± 15 years, eGFR 21 ± 5 ml/min/1.73m2, plasma bicarbonate 21.7 ± 3.3 mmol/l). Sodium bicarbonate supplementation increased plasma bicarbonate (20.8 to 23.8 mmol/l) and reduced urinary ammonium excretion (15 to 8 mmol/day, both P < 0.05). Furthermore, a trend towards lower plasma aldosterone (291 to 204 ng/L, P = 0.07) and potassium (5.1 to 4.8 mmol/l, P = 0.06) was observed in patients receiving sodium bicarbonate. Sodium bicarbonate did not significantly change the urinary excretion of renin, angiotensinogen, aldosterone, endothelin-1, albumin, or α1-microglobulin. Sodium chloride supplementation reduced plasma renin (166 to 122 ng/L), and increased the urinary excretions of angiotensinogen, albumin, and α1-microglobulin (all P < 0.05). Conclusions Despite correction of acidosis and reduction in urinary ammonium excretion, sodium bicarbonate supplementation did not improve urinary markers of the renin-angiotensin system, endothelin-1, or proteinuria. Possible explanations include bicarbonate dose, short treatment time, or the inability of urinary renin to reflect intrarenal renin-angiotensin system activity. Graphic abstract

Background: The FIDELIO-DKD trial evaluated the effect of the nonsteroidal, selective mineralocorticoid receptor antagonist finerenone on kidney and cardiovascular (CV) outcomes in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D) with optimized renin-angiotensin system blockade. Compared with placebo, finerenone reduced the composite kidney and CV outcomes. We report the effect of finerenone on individual CV outcomes and in patients with and without history of atherosclerotic CV disease (CVD). Methods: This randomized, double-blind, placebo-controlled trial included patients with T2D and urine albumin-to-creatinine ratio 30-5000 mg/g and an estimated glomerular filtration rate (eGFR) ≥25-<75 mL/min/1.73 m 2 , treated with optimized renin-angiotensin system blockade. Patients with a history of heart failure with reduced ejection fraction were excluded. Patients were randomized 1:1 to receive finerenone or placebo. The composite CV outcome included time to CV death, myocardial infarction, stroke, or hospitalization for heart failure. Prespecified CV analyses included analyses of the components of this composite and outcomes according to CVD history at baseline. Results: Between September 2015 and June 2018, 13,911 patients were screened and 5674 were randomized; 45.9% of patients had CVD at baseline. Over a median follow-up of 2.6 years (interquartile range, 2.0-3.4 years), finerenone reduced the risk of the composite CV outcome compared with placebo (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.75-0.99; P=0.034), with no significant interaction between patients with and without CVD (HR, 0.85; 95% CI, 0.71-1.01 in patients with a history of CVD; HR, 0.86; 95% CI, 0.68-1.08 in patients without a history of CVD; P-value for interaction, 0.85). The incidence of treatment-emergent adverse events was similar between treatment arms, with a low incidence of hyperkalemia-related permanent treatment discontinuation (2.3% with finerenone vs 0.8% with placebo in patients with CVD and 2.2% with finerenone vs 1.0% with placebo in patients without CVD). Conclusions: Among patients with CKD and T2D, finerenone reduced incidence of the composite CV outcome, with no evidence of differences in treatment effect based on pre-existing CVD status.
