Filter by:Acute renal failure is a frequent complication associated with significant morbidity and mortality in postoperative cardiac surgery. The VExUS (Venous Excess UltraSound grading system) score was created to qualitatively assess this venous congestion, based on ultrasound data from patients obtained post operatively in cardiac surgery. These data included: inferior vena cava diameter, Doppler flow of the suprahepatic veins, portal trunk and renal veins. This score is predictive of the onset of acute renal failure in the first 3 days after surgery. The VExUS score has not been validated in an external and prospective way in cardiac surgery.
Since its inception, KPMP has developed sophisticated protocols for collection and analysis of human kidney tissue, and for collection of biofluids. Members of the consortium have wide-ranging expertise in conducting clinical studies, processing kidney tissue, advanced structural and molecular analysis and complex bioinformatics analysis, which will be used to leverage effectively as a group to better understand kidney disease. This joint protocol aims to synergize the COVID-19 study efforts of KPMP academic research centers, to collectively study COVID-19, including its renal presentation using kidney tissue and/or biofluids from patients suffering from COVID-19. This will increase the breadth and depth of data available to the public to expedite discoveries, identify therapeutics, and improve outcomes for patients with COVID-19. It will additionally bring the expertise of KPMP investigators to bear against this pandemic.
Various forms of organisation in the care of patients with akute kidney injury are investigated. In this prospective study the investigators compare the effect of usual care with the effect of intensive care. Primary endpoint is the development of cardiovascular events ("major adverse cardiovascular events" "MACE").
The primary objective of the study aims to evaluate frequence of acute renal insufficiency in patients with ST-segment elevation who need urgent coronary angiography in Ambroise Paré hospital. The secondary objectives are: - identify factors of risks associated with the occurrence of acute renal insufficiency after coronarography. - establish a preprocedure score, predicting of acute renal insufficiency after urgent coronary angiography in patients with ST+ acute coronary syndrome.
Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: - Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD - Define disease subgroups - Create a kidney tissue atlas - Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: - Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. - Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. - Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.
Pre-market, single-arm, prospective, open-label, multi-center clinical trial aimed at assessing the safety and the performance of the Medyria TrackCath system in patients undergoing endovascular intervention.
Iodinated contrast media are now frequently used in diagnostic imaging exams, including pediatrics. In adults, the acute renal failure (ARF) associated with contrast agents (CA-AKI) occur in 3-33% of exposed patients, especially as the patient is fragile, has comorbidities or pre-existing renal aggression . In children, the prevalence of this little known disease is probably underestimated. The investigators intend to conduct a prospective epidemiological study, to estimate the impact of the acute renale failure to iodinated contrast agents in pediatrics.
In the VERROUREA study, there were two cases of an abnormal increase in TCA. In theory no leakage of the lock into the bloodstream should have been seen. Lock leakage could have particularly serious, and especially clinical, repercussions in these patients who already have a high risk of haemorrhage given the numerous associated comorbidities. The aim of this study is to investigate the leakage of locks into the bloodstream by measuring, before and after injection of the lock, the evolution of haemostasis tests and calcaemia. The findings will complete safety data already collected in the VERROU REA study.
Crescentic IgA nephropathy (CreIgAN) has a poor prognosis despite aggressive immunosuppressive therapy. The efficacy of plasma exchange (PE) in CreIgAN is not well defined. This study will evaluate the efficacy and safety of plasma exchange as adjunctive therapy for severe crescentic IgA nephropathy compared to pulse methylprednisolone on a background of oral prednisolone and cyclophosphamide in prevent kidney failure.
Acute kidney injury is associated with cardiopulmonary bypass during heart surgery and its pathogenesis is similar to that of ischemia-reperfusion injury. Remote ischemic preconditioning attenuates myocardial ischemia-reperfusion injury in patients undergoing coronary bypass surgery. The investigators hypothesize that such preconditioning reduces the incidence of acute kidney injury associated with cardiopulmonary bypass.
