The ability of proximal tubule cells to internalize filtered proteins over a broad concentration range is essential for maintaining a protein-free urine but also renders these cells uniquely susceptible to cytotoxic damage.Morace et al. find that knockout of globotriaosylceramide synthase, an enzyme required for production of Gb3 and other members of the globo series of glycosphingolipids, impairs endocytic uptake of filtered proteins and preserves kidney function in mouse models of acute kidney injury.
This propensity score analysis in patients with pr-AAA undergoing F-BEVAR or OSR suggests no difference in terms of 30-day mortality, dialysis, or organ-specific postoperative complications, with the exception ofAKI.

In this retrospective trial, we investigated pharmacogenomic associations in the multidrug resistance (ABCB1) and cytochrome P450 3A5 (CYP3A5) genes and acute kidney injury (AKI) and chronic kidney disease (CKD) in a cohort of 121 patients.
The expression of organic anion-transporting polypeptide 1a1 (Oatp1a1), Oatp1a4, Oatp1b2 and multidrug resistance-associated protein 2 (Mrp2) in liver was unchanged in AKI rats.
Although the ABL kinase inhibitor imatinib mesylate (Gleevec) provides highly effective treatment for BCR-ABL-positive chronic myelogenous leukemia, it has proven far less efficacious in the treatment of BCR-ABL-positive acute lymphoblastic leukemias (ALLs), many of which sustain deletions of the INK4A-ARF (CDKN2A) tumor suppressor locus.
Cell-free DNA (cFDNA) in serum was isolated and digested with methylation-sensitive restriction enzymes (Bsh1236I, HpaII and HinP1I) to quantify the amount of methylated Adenomatosis-poliposis-coli gene (APC), Gluthation-a-transferase-protein 1 gene (GSTP1), ARF tumor suppressor protein gene (p14(ARF)), cyclin-dependent kinase inhibitor 2A (p16), Retinoid-acid-receptor-beta gene (RAR-B), RAS-association domain family-1 gene (RASSF1), Tissue inhibitor of metalloproteinase-gene (TIMP3) and Prostaglandin-endoperoxid synthase 2 (PTGS2) DNA fragments.
The risk of pRBC transfusion for AKI was greater in ABO-i LT (multivariable adjusted odds ratio (OR) 1.32 per unit) than in ABO-c LT (OR 1.11 per unit).
We investigated the associations of CKD stage, hospitalizations with and without acute kidney injury (AKI), serum potassium, bicarbonate level, thiazide, and loop diuretic use with ACE-I/ARB discontinuation.
All patients presented at least one risk factor for AKI, including concomitant nephrotoxic drugs: gentamicin (n=19), diuretics (n=15), angiotensin-converting enzyme inhibitors (n=8) and angiotensin II receptor-blockers (n=6).
To evaluate whether the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) after hospital discharge is associated with better outcomes in patients with AKI.
Although low activity of RAS has been implicated in the development of neonatal ARF and data indicated that the functionality of RAS is influenced by the I/D variants of the ACE gene and the A1166C variant of the AT1R gene, we could not demonstrate any effect of these polymorphisms on the development of ARF in VLBW infants.
Chronic obstructive pulmonary disease and receiving cardiac catheterization elevated the risk of AKI preferentially in the older-old/old and older-old group, respectively, while the administration of angiotensin-converting enzyme/α-blocker and angiotensin receptor blocker/calcium channel blocker reduced the risk of AKI preferentially in the older-old and older-old/old group, respectively.
Association between exposure to angiotensin-converting enzyme inhibitors and angiotensin receptor blockers prior to septic shock and acute kidney injury.
We investigated whether the concomitant use of diuretics, non-steroidal anti-inflammatory drugs, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (triple whammy, TW) predicts in-hospital acute kidney injury (AKI) and whether admission during recorded periods of extreme heat influences this association.
The preclinical and clinical studies have reported beneficial as well as deleterious effects of RAS blockage either by angiotensin receptor blocker or ACE inhibitor in AKI.
This study aimed to investigate if withholding angiotensin-converting enzyme inhibitors or angiotensin-2 receptor blockers peri-operatively reduces the risk of acute kidney injury following major non-cardiac surgery.
It is unknown whether preoperative use of ACE inhibitors (ACE-I) or angiotensin receptor blockers (ARBs) affects the risk of acute kidney injury (AKI) after colorectal cancer (CRC) surgery.
Controlling for baseline comorbidities, both diuretic and angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use were found to be associated with a twofold risk of acute kidney injury (diuretic - OR 2.06 95% CI:1.30-3.26, P < 0.005, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use OR 2.09 95% CI:1.31-3.32, P < 0.005).
Whether angiotensin-converting enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARB) improve outcome in patients recovering from AKI remains unexplored.
The baseline serum creatinine level, use of angiotensin-converting enzyme inhibitors or angiotensin-II receptor antagonists, red blood cell transfusion volume, and history of coronary artery disease were independent risk factors for AKI.
