Pyridoxamine reduces post-injury fibrosis and improves functional recovery after acute kidney injury.

Pyridoxamine reduces post-injury fibrosis and improves functional recovery after acute kidney injury. Am J Physiol Renal Physiol. 2016 May 18;:ajprenal.00056.2016 Authors: Skrypnyk NI, Voziyan P, Yang H, de Caestecker CR, Theberge MC, Drouin M, Hudson B, Harris RC, de Caestecker MP Abstract Acute kidney injury (AKI) is a common and independent risk factor for death and chronic kidney disease (CKD). Despite promising preclinical data, there is no evidence that anti-oxidants reduce the severity of injury, increase recovery, or prevent CKD in patients with AKI. Pyridoxamine (PM) is a structural analog of vitamin B6 that interferes with oxidative macromolecular damage via a number of different mechanisms, and is in a phase 3 clinical efficacy trial to delay CKD progression in patients with diabetic kidney disease. Since oxidative stress is implicated as one of the main drivers of renal injury after AKI, the ability of PM to interfere with multiple aspects of oxidative damage may be favorable for AKI treatment. In these studies we therefore evaluated PM treatment in a mouse model of AKI. Pretreatment with PM caused a dose-dependent reduction in acute tubular injury, long-term post-injury fibrosis, as well as improved functional recovery after ischemia-reperfusion AKI (IR-AKI). This was associated with a dose-dependent reduction in oxidative stress marker isofuran/F2-isoprostane ratio, indicating that PM reduces renal oxidative damage post-AKI. PM also reduced...

ConclusionsA significant number of patients with T2DM developed acute kidney injury following CABG. There was no difference in infective complications such as pneumonia and catheter-associated urinary tract infection, between the two groups.

ConclusionIncreased urinary PGE2 from elevated SNGFR and consequently increased FFSS during early stage of CKD precedes overt microalbuminuria and is a biomarker for early hyperfiltration-induced injury in individuals with SFK.

Despite receiving complete revascularization using multiple arterial conduits, patients who undergo coronary artery bypass grafting (CABG) are still susceptible to recurrent major adverse cardiovascular events (MACE) owing to the progression of atherosclerotic disease in saphenous vein grafts (SVGs) and native, ungrafted coronary vessels. This is more likely to occur in patients who are obese, have diabetes, have hyperlipidemia, have hypertension, have chronic kidney disease, or who are smokers.

Conclusions: The associated factors of CKD varied by different groups of BMI. These findings may help to develop potential interventions to manage CKD.

AbstractAimsConcerns about the prognostic value of NYHA functional class (FC) in heart failure (HF) patients carrying a prophylactic implantable cardioverter defibrillator (ICD) are still present. We aimed to compare whether mortality and arrhythmic risk were different, in a cohort of HF patients undergoing ICD ‐only implant, according to their FC.Methods and resultsHF patients with left ventricle ejection fraction (LVEF) ≤35%, undergoing first prophylactic ICD‐only implant were collected from a multicentre nationwide registry (2006–2015). Six hundred and twenty‐one patients were identified (101 patients in ...

Abstract Contrast-induced acute kidney injury (CIAKI) is a severe complication associated with the use of iodinated contrast media (CM); a sudden but potentially reversible fall in glomerular filtration rate (GFR) typically occurring 48-72 hours after CM administration. Principal risk factors related with presentation of CIAKI are preexisting chronic kidney disease and diabetes mellitus. Studies on CIAKI present considerable complexity because of differences in CM type and dose, controversies in definition and baseline comorbidities. Despite that, it should be noted that CIAKI poses a serious health problem becaus...

by Jan Menne, Eva Dumann, Hermann Haller, Bernhard M. W. Schmidt BackgroundSodium-glucose cotransporter-2 inhibitors (SGLT2is) represent a new class of oral hypoglycemic agents used in the treatment of type 2 diabetes mellitus. They have a positive effect on the progression of chronic kidney disease, but there is a concern that they might cause acute kidney injury (AKI). Methods and findingsWe conducted a systematic review and meta-analysis of the effect of SGLT2is on renal adverse events (AEs) in randomized controlled trials and controlled observational studies. PubMed, EMBASE, Cochrane library, and wer...

Abstract Circulating microRNAs (miRNAs) have been linked to chronic kidney disease. Little is known about the association between circulating miRNAs and kidney function in patients at high cardiovascular risk. We therefore investigated the association between a panel of candidate miRNAs and kidney function, based on estimated glomerular filtration rate (eGFR), in two independent cohorts of patients undergoing coronary angiography. The present study totally included 438 coronary angiography patients, who were divided into a discovery cohort (n=120) and a validation cohort (n=318). A candidate miRNA panel comprising...
