BACKGROUND: Neutrophilgelatinase-associated lipocalin (NGAL) has been proven to be a useful biomarker for early detection of acute kidney injury, but it is not known whether adding NGAL measurements to conventional risk factors will improve the risk assessment in the setting of chronic kidney disease (CKD). The aim of the present study was to examine the correlation of NGAL with early stage renal impairment in CKD and to evaluate its prognostic value in these subjects. METHODS: This is a prospective observational cohort study of 54 patients with early stage (stage 1-2) CKD...

Dulaglutide (DU) is a once-weekly glucagon-like peptide-1 receptor agonist approved for treatment of type 2 diabetes. Integrated data from 9 phase 2 and 3 trials in type 2 diabetes (N = 6005) were used to evaluate effects of DU on estimated glomerular filtration rate (eGFR, mL/min/1.73m(2) [Chronic Kidney Disease Epidemiology Collaboration]), urine albumin-to-creatinine ratio (UACR, mg/g), and kidney adverse events. No significant differences in eGFR were observed during treatment for DU versus placebo (PL), active comparators (AC), or insulin glargine (IG) (mean±SD; DU: 87...

BACKGROUND: Normal kidney function or, more specifically, normal glomerular filtration rate (GFR) in men and women and its decline with age is still much debated today. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has gender (and race) multiplication factors, accounts for a decline that starts at very young age and assumes that the mean GFR is as high as 120-130 ml/min/1.73 m2 from a young age. The full age spectrum (FAS) estimated mean GFR is about 107 ml/min/1...

BACKGROUND: Researchers have developed several equations to predict glomerular filtration rate (GFR) in patients with chronic kidney diseases (CKD). However, there are scarcely any studies performed to discern the best equation to estimate GFR in patients with pure obstructive nephropathy. In present study, we assessed the suitability of six prediction equations and compared their performance in eGFR evaluation for Chinese patients with obstructive nephropathy. METHODS: A total of 245 adult patients with obstructive nephropathy were enrolled...

Arterial structure and function change progressively with advancing age. Owing to long-lasting repetitive stretch with intermittent cardiac contraction, elastic fibers in the tunica media of large arteries gradually degenerate and are replaced by collagenous fibers. Such medial degeneration causes elastic arteries to stiffen and dilate. However, the speed of the vascular aging varies considerably among individuals; a discrepancy often exists between the chronological age of an individual and the biological age of his or her arteries...

Resistant hypertension is defined as a blood pressure above 140/90 mmHg despite adherence to a combination of at least three optimally dosed antihypertensive medications, one of which is a diuretic. Chronic kidney disease (CKD) is one of the more common patient comorbidities associated with resistant hypertension. Recommended low-salt diet and triple antihypertensive drug regimens that include a diuretic, should be complemented by the sequential addition of other antihypertensive drugs. CKD is associated with premature vascular ageing, characterized by accelerated arteriosclerosis or atherosclerosis and endothelial dysfunction...

The presence of chronic kidney disease (CKD) is a strong risk factor not only for end stage kidney disease (ESKD) but also cerebro-cardiovascular disease (CVD). CKD is defined as GFR < 60ml/min/1.73m and/or the evidence of renal damages for more than 3 months. Epidemiological studies have shown that albuminuria even as little as 10mg/gCr is a strong risk factor for CVD, especially stroke. The significance of albuminuria can be recognized when we think of the fact that the amount of albumin in 24 hour-GFR is as large as 6 kg (4...

Vitamin-K-dependent carboxylation of matrix Gla protein (MGP) protects the macrocirculation against calcification. We recently reported in a multiethnic population study that the estimated glomerular filtration rate, a microvascular trait, decreased and the risk of chronic kidney disease increased with higher circulating levels of inactive dephospho-uncarboxylated MGP, a marker of vitamin K deficiency. These findings highlighted the possibility that vitamin K might have a beneficial effect on the renal microcirculation...

INTRODUCTION: Invasive fungal disease (IFD) is an important complication after solid organ transplantation (SOT). A marked geographic variation in the epidemiology of IFD after kidney transplantation (KT) has been suggested by the results of previous studies. Nevertheless, data from Latin American centers are scarce. OBJECTIVE: This study sought to describe the epidemiology of IFD at a Brazilian KT center. METHODS: This study was a retrospective single-center cohort study that included patients who underwent KT between 1998 and 2009 and were followed up until July 2015...

OBJECTIVE: Plasma copeptin, a surrogate for vasopressin, has been associated with a decline in renal function and albuminuria in population-based studies as well as with progression of diabetic nephropathy in people with type 2 diabetes. We assessed the risk of kidney and coronary events and all-cause mortality associated with plasma copeptin in people with type 1 diabetes. RESEARCH DESIGN AND METHODS: Plasma copeptin was measured in baseline samples of the GENEDIAB (n = 398; 56% male; mean ± SD age 45 ± 12 years and diabetes duration 28 ± 10 years) and GENESIS (n = 588; 52% male; age 42 ± 11 years; diabetes duration 27 ± 9 years) cohorts...
