Active clinical trials for "Renal Insufficiency"

Kidney transplantation is widely considered to be the treatment of choice for children with End Stage Renal Disease (ESRD). The purpose of this study is to determine the safety of sirolimus monotherapy for long-term immunosuppression in children and adolescents after kidney transplantation.

This is an open-label, single-arm, baseline-controlled, multicenter efficacy and safety switch study involving 500 CKD subjects suffering from anemia and treated previously with a stable dose of ESA s.c. Correction of anemia will be maintained by s.c. administration of HX575 in two frequencies (i.e. qw and q2w), in order to maintain an Hb target range of 10.0-12.0 g/dL.

The purpose of this study is to perform a randomized, controlled clinical trial to investigate if the phosphate binder sevelamer can improve insulin resistance and glucose handling in patients receiving maintenance hemodialysis.

This study is intended to assess the safety and tolerance of regadenoson in subjects with renal impairment.

Fondaparinux is an antithrombotic agent having already received a regulatory approval by the European Authorities in venous thromboembolic event prevention after major orthopaedic surgery, as total hip replacement (THR), total knee replacement (TKR), hip fracture (HF). The bleeding risk associated with this prescription is highly related to renal function evaluated by creatinin clearance (CrCl). In order to reduce the bleeding risk, it has been proposed to prescribe fondaparinux 1.5 mg/day in patients with a CrCl between 20 and 50ml/mn instead of 2.5mg/day (European MMA). In the meantime, this approval is essentially based on simulated pharmakinetic data without any support of clinical data. prospective, multicentre, open-label study evaluating the safety profile of fondaparinux 1.5 mg/day, subcutaneously administered, in patients with a renal impairment defined by a CrCl between 20 and 30 ml/min and undergoing a major orthopaedic surgery.

Development of chronic changes (scarring) in transplanted kidney tissue is a major cause of long-term kidney function deterioration and ultimately graft loss. It results from both immunologic and non-immunologic mechanisms. Mycophenolate mofetil (MMF) is immunosuppressive drug used for prevention of rejection after kidney transplant, usually in combination with a calcineurin inhibitor (tacrolimus or cyclosporine), with or without corticosteroids. Besides immunosuppression, MMF may also have direct antifibrotic properties. Tacrolimus has potent immunosuppressive effects and is the cornerstone of contemporary posttransplant immunosuppressive therapy in kidney recipients. However, it is also nephrotoxic. The hypothesis of the present study is that in the setting of similar net immunosuppression, higher dose of MMF (3 g daily) will result in slower progression of kidney fibrosis during first year posttransplant as compared to MMF 2 g daily. To test this hypothesis, the present study will randomly assign low immunological risk kidney transplant recipients to either 2g or 3 g MMF daily, in combination with tacrolimus, with, or without maintenance steroids. All patients will have kidney biopsy at implantation and at 12 months after transplantation. Main outcome will be 1-year change in chronic kidney histology (interstitial fibrosis) assessed by protocol biopsy.

This study will examine the renal sparing impact of implementing a strategy of conversion to everolimus from a calcineurin inhibitor based immunosuppressive protocol at 3 months post liver transplant

The primary purpose of this study is to obtain a preliminary pharmacokinetic profile of MK-7145 2 mg immediate release (IR) following single-dose administration in male participants with moderate renal insufficiency. In addition, the study will evaluate the pharmacodynamic effect of a single dose of MK-7145 2 mg IR on 24-hour net natriuresis in male participants with moderate renal insufficiency.

We aim to investigate the efficacy of N-acetylcysteine (NAC) to attenuate acute renal dysfunction in patients with rheumatic valvular heart disease undergoing single valve replacement.

Patients suffering from end-stage renal disease (ESRD) are dependent on renal replacement therapy (dialysis). The majority of dialysis is facilitated by hemodialysis. For hemodialysis a vascular access is necessary, preferable an arteriovenous fistula (AVF) in which a vein is directly anastomosed to an artery. In order to use the AVF for hemodialysis three criteria have to be met; the minimal flow over the AVF is 600 mL/min, the diameter is at least 6 mm, and the AVF is located less than 6 mm under the skin. Unfortunately, approximately half of the patients (50%) are confronted with an AVF that does not meet these criteria; the so called non-maturation or primary failure. In case of non-maturation the AVF is not only unusable for dialysis, but also requires reinterventions on short- and long-term. Firstly to mature the AVF, and secondly, when the AVF is matured, to keep the vascular access. Using a computational simulation postoperative flow can be predicted. Based on patient-specific duplex measurements, the model can calculate the flow that can be expected following vascular access surgery for all AVF configurations; fore- or upper arm. These calculations lead to an advice which configuration is indicated; a flow that exceeds 600 mL/min, leading to maturation. Potentially the aforementioned 50% of non-maturation can be reduced. The patient then has an adequate vascular access and reinterventions are adverted, resulting in a decrease of costs, hospital demand, and an increase of the patients' quality of life. When the expected reduction of non-maturation is confirmed, the computational tool can be offered to other hospitals.
