Low Dose Continuous Furosemide Effect on Cardiac Surgery Patients With Kidney Dysfunction
Chronic Kidney DiseaseCardiac DiseaseChronic kidney disease is an independent risk factor for cardiovascular disease associated with increased mortality rate during cardiac surgery in proportion to the kidney function. Chronic kidney disease is defined by decreased glomerular filtration rate (GFR) as classified by Kidney Disease: Improving Global Outcome (KDIGO). Deterioration of kidney function has a complex and multifactorial pathophysiologic derangement. In order to counter kidney injury associated with cardiac surgery, several pharmacologic and non-pharmacologic interventions have been studied to prevent perioperative deterioration of kidney function. Diuretics as pharmacologic measure are often used post-cardiac surgery to treat fluid overload and managing patient with acute kidney injury by preventing anuria. Loop diuretics (furosemide) may improve renal blood flow, decrease reabsorption in renal tubules, decrease oxygen demand and energy consumption (blocking potassium/sodium/2cloride co-transport in loop of Henle), and prevent hypoxic injury of renal medulla. Low dose continuous furosemide hypothetically has a protective effect on cardiac surgery patients with kidney dysfunction, measured improved glomerular filtration rate, decreased indication for therapeutic furosemide infusion, and decreased need of renal replacement therapy. On the other hand, administration of furosemide is rather harmful in severe kidney dysfunction. Therefore, the objective of this study is to determine the protective effect of low-dose continuous furosemide perioperative in cardiac surgery patients with mild to moderate kidney dysfunction.
A Study of RBT-3 in Healthy Volunteers and Volunteers With Stage 3-4 Chronic Kidney Disease
Kidney FailureAcuteThis is a Phase 1b, single center, dose-escalating study evaluating the safety, tolerability, and pharmacodynamic effect of RBT-3 in healthy volunteers and in subjects with stage 3-4 chronic kidney disease.
CKDu in Sugarcane Workers in Guatemala
Chronic Kidney DiseaseThe objective of this research project is to investigate specific behaviors and exposures related to sugarcane work and their association with non-communicable diseases, specifically Chronic Kidney Disease of Unknown Origin (CKDu) among sugarcane workers in Guatemala. Over the course of the 6-month sugarcane harvest the investigators will assess risk factors for declining kidney function, and also changes in biomarkers of kidney function pre and post work shift of field and factory workers and their possible relationships with dehydration and heat stress. The investigators will also evaluate the effectiveness of an intervention aimed at increasing hydration and reducing heat stress. Finally the investigators will measure biomarkers of exposure and environmental samples for heavy metals, agrochemicals, and infectious disease (Leptospira).
Is There a Digital Divide in Chronic Kidney Disease (CKD)?
Chronic Kidney DiseaseThis study is looking to improve the safety of patients with chronic kidney disease via education provided on a mobile tablet. This study will additionally examine if electronic tools, such as mobile tablets, can help.
Interleukin-1 Blockade for the Treatment of Heart Failure in Patients With Advanced Chronic Kidney...
Heart FailureSystolic3 moreInterleukin-1 blockade for the treatment of heart failure in patients with advanced chronic kidney disease (End-stage renal disease and Heart fAilure - Anakinra Remodeling Trial) is a Phase 2, single-arm trial designed to estimate the effect of anakinra, a recombinant human Interleukin-1 (IL-1) receptor antagonist, on cardiorespiratory fitness in patients with advanced chronic kidney disease and heart failure.
Supplemented Low Protein Diet and Progression of CKD
Stage 4 Chronic Kidney DiseaseInvestigators intend to analyze diets restricted in protein and supplemented with ketoanalogues of essential amino acids, to slow the progress of renal damage and improve nutritional status in diabetic patients over 60 years with stage 4 chronic kidney disease. Evey 2 months, evaluations were performed of renal function (creatinine clearance, serum cysteine, proteinuria) and nutritional status (subjective global evaluation,dominant had pressure strength, body composition by bioelectric impedance, serum transferrin, serum prealbumin and serum aminogram) for a follow-up period of 2 years.
Soluble CD146 and Proteinuria in Chronic Renal Disease
Chronic Renal FailureChronic renal disease (CKD) is defined as a decrease in glomerular filtration rate (GFR) and / or proteinuria or albuminuria (a protein present in urine). Albuminuria is considered a marker of endothelial dysfunction. Proteinuria and / or albuminuria are recognized as cardiovascular risk factors in both diabetic and non-diabetic populations, independently of GFR. It is also a marker of progression of kidney disease. cluster of differentiation 146 (CD146) is an endothelial adhesion molecule with preferential localization in the junction. Soluble CD146 (or CD146s). CD146s is a biomarker of endothelial dysfunction that is easy to assay. The increase in CD146 levels was described during the MRC, especially in diabetic patients with significant proteinuria. In two independent cohorts of patients with CDR, CD146s did not correlate with creatinine or GFR but appeared to correlate with proteinuria. The aim of our study is to determine whether the blood concentration of CD146s is correlated with proteinuria independently of GFR. For this purpose, we propose this study in the kidney nephrology and transplantation center of Conception Hospital, with the objective of highlighting the link between proteinuria and serum CD146 levels in patients with CKD, whatever their renal function and / or underlying pathology. 205 patients will be included over two years with dosing of CD146s and proteinuria at the same time. These 205 patients will be recruited at each stage of the CKD (41 in each arm). CD146s could be a new biomarker predicting the risk of renal function impairment or cardiovascular risk independent of renal function.
Reducing Hemodialysis Induced Recurrent Brain Injury to Improve Patients' Lives
Chronic Kidney DiseasePatients who receive dialysis for kidney failure suffer severe cognitive impairment. Hemodialysis causes circulatory stress and ischemia, which causes severe brain injury. It has been demonstrated that a procedure known as Remote Ischemic Preconditioning(RIPC), which involves wrapping a blood pressure cuff around a patient's leg and inflating has the potential of protecting many organs, such as the heart from the effects of dialysis. Our study aims to investigate this phenomenon to determine the extent to which it provides protection to a dialysis patient's brain.
