Filter by:This is a Phase 1, open-label, single-dose study of the safety, tolerability, and pharmacokinetics of Minocin® (minocycline) for injection in subjects with renal insufficiency.
Numerous catheter designs have been studied to increase efficacy and minimize complications of catheter hemodialysis. Major complications of catheters include thrombosis, central venous stenosis, infection, and dialysis inadequacy. Thrombosis must be avoided if possible because using too many catheters may exhaust all of the catheter insertion sites on the body, as well as increase the risk of infection. This prospective study compares the complications and general outcomes of patients who receive hemodialysis using the mainstream Palindrome catheter versus the newer BioFlo DuraMax catheter. This study will examine outcomes of patients who receive hemodialysis using either the Palindrome catheter or the BioFlo catheter. Patients will be observed and outcomes will be recorded for three to six months. Outcomes will be analyzed and compared to draw conclusions on which catheter produces less catheter thrombosis.
Aim of this study is to evaluate in a population of old osteoporotic chronic kidney disease females the effect of denosumab: - on bone mineral density (femoral T-score) at 24 months - on bone mineral density evolution (femoral T-score) after 24 months of follow-up - on bone mineral density evolution (lumbar T-score) after 24 months of follow-up - on coronary and abdominal aorta calcification scores evolution after 24 months of follow-up - on parameters of bone remodelling (OPG, RANKL, sclerostin, DKK-1), of mineral and calcium metabolism (FGF23 Ct, Klotho, PTH, 25(OH) vitamin D3, phosphorus, calcium, bone alklaline phosphatase, osteocalcin, CTX), of inflammation (CRP) after 24 months of follow-up - on cardiovascular morbidity (cardiovascular events) and mortality after 24 months of follow-up - the tolerance after 24 months of follow-up
Heart failure (HF) is an epidemic and is a major burden on the US healthcare system. The most common cardiovascular endpoint is HF. Thus, novel interventions to prevent HF in chronic kidney disease (CKD) are highly desirable. This study will assess: the variability in the response to isosorbide mononitrate (ISMN) therapy; the degree of change in central hemodynamics and cardiac endpoints through analysis of changes in left ventricle (LV) mass, diffuse myocardial fibrosis, and myocardial systolic and diastolic function.
The goal of this pilot study is to determine whether oral sodium bicarbonate can raise low serum bicarbonate concentration in people without chronic kidney disease (CKD). Participants will take sodium bicarbonate for six weeks, followed by a four week washout period.
This trial is to establish whether ultrafiltration by peritoneal dialysis is a clinically effective treatment for patients with severe heart failure and moderate chronic kidney disease, thus improving quality of life and symptoms.
Prospective, multi-center study to evaluate the everlinQ endoAVF System when used to create an endovascular arteriovenous fistula (endoAVF) for patients who require vascular access for hemodialysis.
Patients with chronic kidney disease (CKD) experience fatigue and exercise intolerance. Increased oxidative stress in CKD may be a contributing factor. The role of impaired muscle blood flow regulation has not been fully explored. The investigators hypothesize that functional sympatholysis is exaggerated in CKD and this is associated with increased oxidative stress. The investigators also hypothesize that exercise training will improve functional sympatholysis and oxidative stress
The creatinine clearance will be measured using two consecutive 24 hour urine collections, with the objective of minimizing errors due to poor quality urine collection. The GFR will be measured by a reference method, because its estimation from blood creatinine levels (eGFR) by the MDRD study formula may be confounded by variations in muscle mass, and therefore creatinine production, following bariatric surgery. The method will remain the same in each center, and therefore consistent for any given patient, throughout the duration of the study. The GFR measurements will be performed after stopping any medication blocking the RAAS, and reducing diuretics for one week, with the introduction or increase of alpha-blockers or centrally-acting hypotensive agents. If it is impossible to stop RAAS-blockade (heart failure), the dose will at least be reduced for one week. This precaution is required to minimize the bias of functional renal insufficiency because the state of extracellular hydration is difficult to assess in obese subjects. Subsequent measurements of GFR will be performed in the same way. The choice of the tracer to measure GFR may vary according to study center. 51Cr-EDTA, 99Tc-DTPA, iohexol or inulin may all be utilized. Because the assessment of edema is hazardous in extremely obese patients and because kidney disease favors edema formation, the simplified single injection method and the determination of plasma clearance measurement of the tracer is not reliable . Only the constant infusion method will be used to measure GFR. Briefly, GFR will be determined by calculating the glomerular clearance (Cl) from plasma concentrations (P) and renal excretions per unit of time (UxV) during infusion at a constant plasma level of the tracer (Cl=UxV/P). The result will be given as mean value of several consecutive clearances. Because correct urine collection is key for the procedure, seven collection periods (instead of 5 usually) will be performed for the calculation of the mean clearance. Bladder catheterization will be used only when it can be anticipated that the patient will not void satisfactorily. In the last 30 consecutive patients with mGFR below 60 ml/min/1,73m2, this occurred twice and the subjects were 70 and 79 years old. Therefore, this might occur exceptionably in the study. Raw data from each center will be sent to the coordination center (Nice) to examine and validate the calculation of mean clearance values. To that aim, extreme and non-representative clearances will be excluded. At least 3 of the 7 periods will be taken into account to calculate the mean values. For instance, in the last 30 consecutive patients with mGFR below 60 ml/min/1,73m2, investigators considered on average 4.7 periods and obtained a mean non-indexed GFR value of 40,7 ± 2,5 ml/min. Primary assessment will be performed at one year, as a previous study has already suggested a significant benefit within this period [66], and because surgery can't be delayed further in these patients strongly expecting the intervention, but follow-up will be extended to three years or until the end of the study, in order to document whether the initial benefits of surgical intervention are maintained. - A reduction in the absolute value of measured GFR (mGFR) following bariatric surgery is expected in the first six months after surgery (M0 - M6). However, the weight loss may allow an increased in mGFR indexed to body surface area up until M6, and above all towards M12. - the investigators expect a subsequent stabilization of mGFR between M12 and M36 in the bariatric surgery group, and will seek to measure the anticipated reduction in mGFR in the control group who remain in a state of glomerular hyperfiltration. All relevant cardiovascular, metabolic and nutritional parameters necessary to study the risk/benefit ratio of the intervention will be analyzed. - Primary: bariatric surgery slows the progression of chronic kidney disease in the obese. - Secondary: bariatric surgery improves survival, cardiovascular prognosis, metabolic, nutritional and inflammatory parameters, quality of life, and access to transplantation in the sub-group of patients whose GFR < 20ml/min/1.73m2 at inclusion, and there could be a chance loss for the patients in delaying surgery by one year.
The proposed pilot study challenges the current widespread paradigm of discontinuing loop diuretics when initiating chronic HD and/or maintaining the dialysate at a constant temperature of 37 °C for all patients.
