Active clinical trials for "Renal Insufficiency"

The investigators propose to conduct a nationwide (Nigeria), prospective, non-interventional cohort study describing the clinical course, biological characteristics, case management and outcomes in patients hospitalized for a suspected or confirmed diagnosis of Lassa fever in tertiary medical facilities situated in the most affected Nigerian states. Special focuses will be made on situations at risk of bad outcome such as pregnancies, acute kidney injury and electrolytic imbalance in patients with confirmed Lassa fever. Participants for which the diagnosis of Lassa fever will be finally excluded by reverse-transcriptase polymerase chain reaction (RT-PCR) will constitute the control group.

VAVASC trial is an observational multicentre study. The aim of this trial is to validate AVAS (arteriovenous vascular access stage) classification. The classification is used for determining which type of access is the most suitable for the patient on the basis of the patient´s vascular anatomy The methodology of this trial is to apply AVAS classification on patients who are indicated for creation of vascular access for hemodialysis. Data on these patients (vascular anatomy status, AVAS type, and predicted type of arterio venous access, demographic data etc.) will be than statistically analysed. Patients will then undergo creation of the selected arteriovenous access. They will be observed in terms of the access functionality. The follow up will be 1 to 3 years. The second aim of this study is to evaluate the relationship between AVAS classification and uninterrupted use of the created arterio venous access.

International, multicentre, randomized 1:1 controlled trial to prove the clinical and medico economic benefits of the medical device Predigraft, by showing that the use of Predigraft could improve patient's follow-up.

The prediction and early detection of acute renal failure associated with cardiac surgery (ARF-CS) are desirable in order to try to reduce its magnitude. Indeed, its incidence is high (29 to 36%, reaching up to 81% in some series, depending on the vulnerability of the target population) and its consequences are often serious: prolongation of the length of stay in the intensive care unit and in hospital, death, and evolution towards chronic renal failure, possibly end-stage (justifying long-term extra-renal purification and/or renal transplantation). The challenge is all the more crucial given the high volume of cardiac surgery. In this context, the objective of identifying early on patients at high risk of developing AKI-CC - and therefore eligible for "nephroprotective" measures has generated, in the last decade, a strong interrest around preoperative scores and biomarkers. Thus, more than ten models predicting AKI-CC have been developed and more than 150 candidate biomarkers have been identified since 2004. This insterest is not waning. The DETECT-AKI project aims to evaluate, in a large population (N=400 patients) with varied patient profiles, not only the performance of the most innovative and promising preoperative scores and biomarkers described in the literature, but also the combination of biomarkers with relevant perioperative clinical and biological data in the framework of a clinico-biological score for the early identification of AKI-CC

Evaluation of non-invasive prognostic parameters in patients developing ACLF and renal failure in patients receiving and not receiving transjugular intrahepatic portosystemic shunt (TIPS). Patients are cared according to the local standardized follow up program. Clinical and laboratory data from standard patient care are evaluated for potential prognostic value.

The main objective of this study is to evaluate the feasibility of estimating the prevalence of stage 4 and 5 chronic kidney disease in the Gard department of France from data obtained via laboratory databases. To verifiy if the demand for care thus authenticated by laboratory tests is adapted to nephrology care delivery, as recommended by the French High Authority of Health (HAS), laboratory data will be compared with those of patients seen by nephrologists in the department.

Evaluation of macro and microcirculatory arterial condition of the upper limb in insufficiently renal patients Hand ischemia affects 1.6 to 8% of patients with arteriovenous fistula (FAV) of hemodialysis in the upper limb. The diagnostic and therapeutic stakes are major as it concerns the functional prognosis of the hand and, to a lesser extent, vascular access for hemodialysis. In some cases, the diagnosis of ischemic hemo-hijacking is evident, in other cases, the ischemic condition appears to be rather the result of uncompensated arteriatory of the upper limb or limbs. Echo-doppler exploration is usual for assessing vascular access but without validated formal criteria for arterial disease in the upper limbs, with fistula flow calculation and analysis of FAV hemodynamics. Compression manoeuvres on or under the FAV can also be performed. The pressures of the digital arteries are also indicated with non-consensual values found in the literature for the diagnosis of digital ischemia but with varying tools in terms of collection of measurements. The main objective of this study is to collate the characteristics of arterial condition of the upper limbs of medium or severe renal patients, medium- or short-term candidates for kidney dialysis. The data collected will match the data of the arterial echodoppler as well as measures of pressures doppler laser and plethysmography. Candidates for dialysis tend to be older and polyvascular. A better assessment of the vascular condition of their upper limbs, including the diagnosis of advanced arterial disease, could eventually guide the choice of type of dialysis (compared to an indication of FAV).

Despite many advances in our understanding of the natural history and progression of chronic kidney disease (CKD) and cardio vascular disease (CVD) in the parent CRIC study over the past 15 years, important questions about key risk factors for these diseases remain unanswered in the AI population. To address this burden of CKD in AI communities Investigators formed a consortium of investigators with extensive experience in conducting research of chronic diseases including diabetes, cardiovascular and kidney disease in AIs of Southwestern US. The proposed CRIC ancillary cohort study of 500 AIs (AI-CRIC) will rapidly improve our understanding of both potential risk factors for CKD progression, as well as the scope of this disease among AIs. This study leverages the current CRIC study and incorporates the planned activities of the next phase of the study - "CRIC 2018" - by implementing contemporary CRIC protocols for kidney and cardiovascular measurement and outcomes.
