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 …
Renal and neurologic effects of cadmium, lead, mercury, and arsenic in children: evidence of early effects and multiple interactions at environmental…
2006
We read with great interest the article by de Burbure et al. (2006) on health effects in children who live near nonferrous smelters in France, the Czech Republic, and Poland. We were especially interested in the inverse relationship found between levels of urinary mercury and serum prolactin. We found a similar result in an Italian multicenter crosssectional survey with adult subjects (Alessio et al. 2002) using a different statistical approach based on regression analysis with mixed linear models. We found that serum prolactin decreased as a function of both urinary mercury and occupational exposure to inorganic mercury (Lucchini et al. 2003). In another study (Carta et al. 2003), our grou…
Metformin and contrast-induced acte kidney injury in diabetic patients treated with primary percutaneous coronary intervention for ST segment elevati…
2016
IF 4.638; International audience; AIM : To analyze the association between chronic metformin treatment and the development of contrast-induced acute kidney injury (CI-AKI) after primary percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI).METHODS: Patients with type 2 diabetes mellitus (T2DM) treated with PCI 27μmol/l (0.3mg/dl) or >50% over baseline after PCI. Since PCI was urgent, metformin could not be withheld prior to PCI but was usually stopped after PCI.RESULTS:Among the 372 patients included, 147 (40%) were using metformin, which had older diabetes, but had risk factors similar to patients without metformin. Baseline eGFR was better in pati…
Plasma homocysteine levels are independently associated with the severity of peripheral polyneuropathy in type 2 diabetic subjects.
2012
Peripheral polyneuropathy (PN) is a frequent complication of diabetes. However, mechanisms underlying the development of PN are multifactorial and not well understood. Our aim was to examine the association of plasma homocysteine (Hcy) with the prevalence and grade of peripheral PN in patients with type 2 diabetes (T2DM). We studied a cohort of 196 subjects with T2DM classified according to the grade of PN (Neuropathy Disability Score, NDS). Subjects with the highest grade of PN were older and had significantly increased levels of creatinine, microalbuminuria, HbA1c, and plasma Hcy compared to the other two groups. The differences in plasma Hcy values were maintained after correcting for co…
Risk factors for contrast induced nephropathy: A study among Italian patients
2012
This study aimed to make a profile of patients at highest risk of developing contrast induced nephropathy (CIN) in order to take appropriate prevention measures. 591 patients undergoing coronary procedures were divided into two groups: patients with (CIN-group) and without (no-CIN) an increase in creatinine level equal or more than 25% from baseline values within 24-48 h after the coronary procedure. All patients underwent an accurate anamnesis, objective exam, hematochemical measurements, and diagnostic exams. The results of this study while confirming that, average age (p = 0.01), diabetes mellitus (p < 0.0001), base line renal insufficiency (p = 0.0001), diuretic therapy (p = 0.002), hig…
Analysis of N-terminal pro-B-type natriuretic peptide in patients with acute coronary syndromes
2009
Background The N-terminal portion of brain natriuretic peptide (NT-proBNP) has been identified as an indicator of prognosis in different cardiovascular diseases. The objective of this study was to determine the utility of measuring plasma NT-proBNP levels in patients with acute coronary syndromes. Methods and results We studied 66 patients admitted in our division for acute coronary syndromes. Patients underwent a venous blood sample within 24 h from the admission to determine NT-proBNP levels. Increasing plasma levels of NT-proBNP (in tertiles) was associated with a greater history of hypertension and current smoking, whereas biochemical parameters were associated with higher level of crea…
Antigen carbohydrate 125 and creatinine on admission for prediction of renal function response following loop diuretic administration in acute heart …
2014
The use of loop diuretics in acute heart failure (AHF) is largely empirical and has been associated with renal function impairment by reducing renal perfusion but also renal improvement by decreasing renal venous congestion. Antigen carbohydrate 125 (CA125) has emerged as a proxy for fluid overload. We sought to evaluate whether the early changes in creatinine (ΔCr) induced by intravenous furosemide doses (ivFD) differ among clinical groups defined by overload status (CA125) and creatinine on admission (Cr).We included 526 consecutive patients admitted for AHF. All patients received intravenous furosemide for the first 48 hours. CA125 and Cr were dichotomized at 35 U/ml and 1.4 mg/dl, respe…
CAPD + hemoperfusion once a week in the management of children with end-stage renal disease
1983
With hemoperfusion there is a sharp decline in the solute concentration of the blood compartment, but immediately after HP the concentration of these substances rises to the original level (post-Hp rebound). It may be inferred that the result would be better and the rebound phenomenon less marked if hemoperfusion could be combined with a continuous dialysis system such as CAPD. The study was performed in 3 children of our CAPD programm. All patients were dialysed with 5 daily exchange each of one liter. The patients underwent at 2-hours hemoperfusion with a charcoal column (Gambro Adsorba 150 c) once a week. The data obtained with this form of treatment are indicative for a: significant in…
Early serum creatinine changes and outcomes in patients admitted for acute heart failure: the cardio-renal syndrome revisited.
2017
Background: The changes in renal function that occurred in patients with acute decompensated heart failure (ADHF) are prevalent, and have multifactorial etiology and dissimilar prognosis. To what extent the prognostic role of such changes may vary according to the presence of renal insufficiency at admission is not clear. Accordingly, we sought to determine whether early creatinine changes (Cr) (admission to 48-72 hours) had an effect on 1-year mortality relative to the presence of renal insufficiency at admission. Methods: We included 705 consecutive patients admitted with the diagnosis of ADHF. Admission renal insufficiency was defined as serum creatinine 1.4mg/dl (A-RIcr) or estimated gl…
Unfavourable interaction of microalbuminuria and mildly reduced creatinine clearance on aortic stiffness in essential hypertension
2010
The aim of our study was to assess the independent relationships of urinary albumin excretion rate (AER), of creatinine clearance (CrCl) and of their interaction with aortic stiffness in hypertensive patients without overt renal insufficiency. We studied 222 untreated nondiabetic essential hypertensives. In patients with reliable 24-h urine collections, AER and CrCl were determined. Microalbuminuria (MAU) was defined as an AER of 20 to 200microg/min. Aortic stiffness was assessed by measurement of carotid-femoral pulse wave velocity (c-f PWV). C-f PWV was higher in subjects with MAU than in those without it (p<0.001, even after adjustment for age, sex and mean arterial pressure) and in subj…
