    Content: Background: N-terminal-pro brain natriuretic peptide (NT-proBNP) is a useful cardiac marker that is also influenced by renal dysfunction. It was our objective to assess the relationship between NT-proBNP concentrations in plasma and worsening renal function, and to attempt adjustment of NT-proBNP for renal dysfunction in a prospective, stratified multi-center study. Methods: We stratified 203 male patients according to their cardiac status and the estimated glomerular filtration rate (eGFR). Cardiac disease was assessed by medical history, physical examination and standardized echocardiography. Patients were stratified according to the following: absence of cardiac history and abnormalities (control, CTRL, n=66), cardiac history without left ventricular hypertrophy (LVH) or left ventricular systolic dysfunction (LVD) (history, n=30), LVH without systolic dysfunction (LVH, n=68), and LVD [ejection fraction (EF) <40%, LVD, n=39]. Renal disease was stratified according to the eGFR: 15–30 mL/min (n=52), 31–75 mL/min (n=99), and >75 mL/min (n=52). Results: NT-proBNP was correlated with eGFR in the entire study population and for all levels of cardiac disease (all p<0.01). Regression analysis allowed adjustment of NT-proBNP for eGFR in a continuous manner, and this adjustment significantly improved the predictive value (receiver operating characteristic curve for symptomatic LVD from 0.80 to 0.86, p<0.01; sensitivity from 74% to 83% and specificity from 68% to 79%). Conclusions: NT-proBNP correlates inversely and significantly with eGFR throughout all levels of cardiac strata. We propose for the first time a continuous adjustment algorithm which markedly improves the predictive values of NT-proBNP in male patients with impaired renal function.

    Series Statement: Oxidative Stress in Applied Basic Research and Clinical Practice
    Content: Conditions such as oxidative stress and hypoxia, which have a generalized impact on the oxygen metabolism, have been implicated in the genesis of kidney disease. This means that deepening our understanding of the pathobiology of oxygen metabolism in such diseases could be a fruitful path towards tangible clinical benefits. Studies in Renal Disorder collects reviews from leading researchers and clinical scientists working in exactly this field, providing an overview of the latest advances. The causal role of impaired oxygen metabolism in kidney disease has numerous clinical implications. It affects our understanding of the therapeutic benefits accruing from anti-hypertensive agents, the way we control hyperglycemia/hyperinsulinemia and hyperlipidemia, and our use of dietary approaches to the correction of obesity. The defensive mechanisms against oxidative stress, such as the Nrf2-Keap1 system, and hypoxia, such as the PHD-HIF system, have recently been explored in various cells, including kidney cells. These mechanisms include intracellular sensors for oxidative stress and hypoxia. This means that novel approaches targeting these sensors may offer clinical benefits in kidney disease in which oxidative stress and/or hypoxia is a final, common pathway.
