Renal Impairment Associated With Colistin Levels
SepsisColistin is a relatively old antibiotic drug which its use has been abandoned through the 1970s because it was considered nephrotoxic. Recently ( the last decade) it has been reappraised because multidrug resistant Gram negative bacteria have emerged causing life threatening infections with no other good enough treatment. Moreover, more controlled studies from the recent years show less toxic effect of the drug. The investigators' study is a prospective study comparing renal function in a group of hospitalized patients with sepsis (infection) receiving intravenous treatment with Colistin (antibiotics) with a control group which its patients receive other non nephrotoxic antibiotics. The investigators' study hypothesis is that patients receiving Colistin would have renal function decline in higher rates than those seen usually in hospitalized patients in the Internal medicine wards with sepsis. Another goal of the study is to find correlation between Colistin levels in the plasma (after Colistin reaches steady state) and nephrotoxicity seen during or after use of this drug.
Comparing Absorption of Dietary Phosphorus When Administering FOSRENOL® or RENVELA® in Healthy Adult...
Kidney FailureChronicThe purpose of this study is to compare the absorption of dietary phosphorus following a single dose with lanthanum carbonate (1000mg) and a single dose of sevelamer carbonate (2400mg).
Examining New Diagnostic Tests for Acute Kidney Injury After Heart Surgery
Kidney FailureAcute1 morePeople who undergo coronary artery bypass grafting (CABG) or heart valve surgery may experience acute kidney injury (AKI) after their surgery. Current medical tests cannot identify AKI until approximately 48 hours after it occurs. This study will examine three new biomarkers in blood and urine that may provide a more effective and faster way of predicting AKI in people who undergo CABG or heart valve surgery.
National Cooperative Growth Study in CKD
Growth Hormone DeficiencyThe purpose of this study is to learn whether growth hormone being administered to children with Chronic Kidney Disease is effective and if it has any side effects.
Pharmacokinetic Study of Genasense in Subjects With Normal Renal Function, Mildly Impaired Renal...
Normal Renal FunctionMildly Impaired Renal Function1 moreTo characterize the pharmacokinetics of G3139 in subjects with normal, mildly impaired, and moderately impaired renal function who receive Genasense 3 mg/kg/day by continuous intravenous infusion for 2 days (48 hours).
Identification of Cardiovascular Risk Factors Linked to Renal Failure Progression
Chronic Renal FailureThe aim of this study is to appreciate the influence of renal failure progression on vasculopathy (coronary calcifications and left ventricular hypertrophy) and cardiovascular risk factors.
Sequential Cystatin C Levels and Renal Impairment in Acute Heart Failure
Acute Heart FailureRenal FailureRenal Compromise after treatment of decompensated heart failure with diuretics is not uncommon. The purpose of our study is to investigate the relationship between cystatin C and worsening renal function in this setting. Cystatin C is a biomarker produced at a constant rate by all cells that is a sensitive biomarker of renal function.Cystatin C and Plasma amino terminal proB-type natriuretic peptide (NT-proBNP) levels will be obtained at baseline and daily. Our goal is to enroll 100 subjects with an estimated 5 samples per each subject. The time course of changes in cystatin C in relation to serum creatinine levels over time will be plotted. Our hypothesis is that sequential changes in cystatin C levels following initial treatment with diuretic therapy in the setting of acute decompensated heart failure may provide early insight into cardio-renal compromise. Understanding the natural history and time course of the changes in sequential cystatin C levels may facilitate further studies to guide the judicious use of diuretic therapy in acute decompensated heart failure, and to predict the risk of subsequent development of worsening renal function. If serial testing of cystatin C can provide accurate assessment and prediction of worsening renal function, clinical applications of these observations can be evaluated in future prospective studies.
