Cystatin C and cardiovascular mortality in patients with coronary artery disease and normal or mildly reduced kidney function: results from the Ather…
2009
Aims Chronic kidney disease is associated with increased risk of cardiovascular disease. Cystatin C is a promising marker to reliably mirror renal function. The role of cystatin C in patients with coronary artery disease (CAD) and normal or mildly reduced kidney function is the subject of current investigation. Methods and results In 2162 patients, over the whole spectrum of CAD, baseline cystatin C concentrations were measured. Patients with an estimated glomerular filtration rate of ≤60 mL/min per 1.73 m2 ( n = 295) were excluded. In patients with complete follow-up information ( n = 1827), 66 cardiovascular deaths were registered during a median follow-up of 3.65 years. Logarithmically t…
Urinary albumin excretion and glomerular filtration rate across the spectrum of glucose abnormalities in essential hypertension.
2006
The objective of this study was to assess the relationship between urinary albumin excretion (UAE) and GF across the spectrum of the glucose metabolism abnormalities in a large population of patients with hypertension. The Microaluminuria en Pacientes con Glucemia Basal Alterada (MAGAL) is a multicenter, cross-sectional study that was carried out by 1723 primary care physicians. A total of 6227 patients with essential hypertension (in three groups: [1] normal fasting glucose100 mg/dl, [2] impaired fasting glucoseor =100 to 126 mg/dl, and [3] type 2 diabetes) were analyzed in this substudy. GFR was estimated by using the Modification of Diet in Renal Disease (MDRD) abbreviated equation. A si…
Blood urea nitrogen to creatinine ratio is associated with congestion and mortality in heart failure patients with renal dysfunction
2015
Renal dysfunction (RD) and venous congestion are related and common in heart failure (HF). Studies suggest that venous congestion may be the primary driver of RD in HF. In this study, we sought to investigate retrospectively the relationship between common measures of renal function with caval congestion and mortality among outpatients with HF and RD. We reviewed data from 103 HF outpatients (45 males, mean age 74 years, ejection fraction 41.8 ± 11.6 %) with estimated glomerular filtration rate (eGFR) of 25.5 (adjusted OR 2.98, p 0.015) and eGFR ≤45.8 (adjusted OR 5.38, p 0.002) identify patients at risk for caval congestion; a BUN/Cr >23.7 was the best predictor of impaired collapsibility …
Effects of statins on lipid profile in chronic kidney disease patients: a meta-analysis of randomized controlled trials
2013
The available data on statin effects in chronic kidney disease (CKD) patients are still conflicting. We investigated the impact of short- and long-term statin therapy on lipid profiles in CKD patients requiring or not requiring dialysis.Data from Scopus, PubMed, Web of Science, and the Cochrane Library from 1966 to May 2012 were searched for studies that investigated this effect. We included all randomized controlled clinical trials that investigated the impact of statin therapy on lipids and lipoproteins.The final analysis included 16 trials with 3594 subjects. In CKD patients, statin therapy significantly reduced total cholesterol (TC), triglycerides (TG) and low-density lipoprotein chole…
Progression of aortic pulse wave velocity in patients with chronic kidney disease.
2013
Aortic pulse wave velocity (aPWV) is elevated in patients with chronic kidney disease (CKD) and predicts cardiovascular risk. However, the natural progression of arterial stiffness in these patients remains uncertain. Therefore, the main aim of this study was to investigate the development of aPWV and to identify potential factors associated with its progression. aPWV measurement was carried out in 70 CKD patients at baseline and after 12 months. Correlations to several variables, in particular annual glomerular filtration rate reduction and diabetes mellitus, were studied. In the cohort, aPWV significantly increased in 1 year by 1.1 m/s (P<.01). Dividing the group into patients with stable…
Impact of Accessory Renal Artery Coverage on Renal Function during Endovascular Aortic Aneurysm Repair.
2021
Background Long-term outcomes of accessory renal artery (ARA) coverage after endovascular aneurysm repair (EVAR) are unknown. We analyzed the impact of ARA coverage on renal function long-term. Methods This retrospective, monocentric study included patients treated by EVAR between 2008 and 2016. Patients with at least one ARA covered with EVAR (ARA group) were compared with patients with no covered ARA (control group). Renal function was determined by estimating the glomerular filtration rate (eGFR) and graded according to chronic kidney disease (CKD) classification stages. Results A total of 184 patients were included (ARA group, n = 25; control group, n = 159). Renal risk factors were sim…
The Fate of Nephrons in Congenital Obstructive Nephropathy: Adult Recovery is Limited by Nephron Number Despite Early Release of Obstruction
2015
Urinary tract obstruction and reduced nephron number often occur together as a result of maldevelopment of the kidneys and the urinary tract. We determined the role of nephron number on adaptation of the remaining nephrons of mice subjected to neonatal partial unilateral ureteral obstruction followed through adulthood.Wild-type and Os/+ mice (the latter with 50% fewer nephrons) underwent sham operation or partial unilateral ureteral obstruction in the first 2 days of life. Additional mice underwent release of unilateral ureteral obstruction at 7 days. All kidneys were harvested at 3 weeks (weaning) or 6 weeks (adulthood). Glomerular number and area, glomerulotubular junction integrity, prox…
Prevalence of erectile dysfunction in patients with chronic kidney disease: a systematic review and meta-analysis.
2020
Growing evidence reports that chronic kidney diseases (CKD) might play a role in erectile dysfunction (ED), but limited knowledge is available. Therefore, we performed a systematic review up to 21/08/2019 to investigate the associations between CKD and ED. The main analysis reported the prevalence of ED as absolute estimates (in %) with their 95% confidence intervals (CIs) and across CKD stages (when specified), hemodialysis and transplant, calculating the p for interaction across strata. Among 291 studies, we included 34 articles with 5986 men. We found an overall prevalence of 76% (95%CI: 72–79) with a high degree of heterogeneity (I2 = 84.2%; p < 0.0001). Analyzing the data by CKD sta…
Para-perirenal distribution of body fat is associated with reduced glomerular filtration rate regardless of other indices of adiposity in hypertensiv…
2018
Obesity is a well‐known risk factor for the development and progression of chronic kidney disease. Recently, para‐perirenal ultrasonographic fat thickness (PUFT) has shown to correlate with both total and visceral fat better than body mass index (BMI), waist circumference (WC), and other indices of obesity. Moreover, a local paracrine and mechanical action of the PUFT on kidney has been described in recent studies. Aim of our study was to assess the relationship between glomerular filtration rate (GFR) and PUFT in comparison with other anthropometric and ultrasonographic indices of adiposity. Two hundred and ninety‐six hypertensive patients were enrolled. PUFT, cutis‐rectis thickness and re…
Continuous ambulatory peritoneal dialysis as a therapeutic alternative in patients with advanced congestive heart failure.
2012
Aims Continuous ambulatory peritoneal dialysis (CAPD) has been proposed as an additional therapeutic resource for patients with advanced congestive heart failure (CHF). The objective of this study was to determine the therapeutic role of CAPD, in terms of surrogate endpoints, in the management of patients with advanced CHF and renal dysfunction. A total of 57 candidates with New York Heart Association (NYHA) class III/IV CHF, renal dysfunction (glomerular filtration rate , 60 mL/min/1.73 m 2 ), persistent fluid congestion despite loop diuretic treatment, and at least two previous hospitalizations for acute heart failure (AHF) were invited to be included in the CAPD programme; however, 25 pa…
