REN and chronic kidney disease: In a meta-analysis evaluating 19 studies, it was observed that finerenone added to renin-angiotensin-aldosterone system blockers in non-transplant chronic kidney disease patients provided a 38.7% decrease in proteinuria, and the fact that almost the same result was obtained in our study suggests that the drug may be effective in kidney transplant patients as in non-transplant CKD [8,23].
