Renal FailureRenal Insufficiency1 moreThe purpose of this research study is to find out the safety and effectiveness of a new medical device called H-Guard. During this research study, participants will receive the standard of care haemodialysis treatment, as decided by the treating doctor. Participants will be observed during 4-5 haemodialysis treatments throughout the course of the study. The only change to the treatment process, will be the use of the medical device (H-Guard) to prime the dialysis system, before one of the treatments. Participants will have various blood tests taken throughout the course of the study for safety and research analysis.
Honoring Individual Goals and Hopes: Implementing Advance Care Planning for Persons With Kidney...
Kidney DiseasesKidney FailureThe PCORI HIGHway project name embodies its goal: the way to "Honor Individuals Goals and Hopes". HIGHway trains and supports dialysis center social workers and nurses to communicate with their patients about their hopes and goals for their future care plans. This process, known as advance care planning (ACP), helps relieve patient concerns about the future, lays the foundation for better goal-concordant care at the end of life, and fosters deeper connection between patient and the dialysis care team. The HIGHway project will provide training and ongoing coaching to social workers and other change team members at 50-60 dialysis centers throughout the US. The goal is to integrate advance care planning conversations between dialysis patients and their health care team into the ongoing workflow of dialysis centers. The project is funded by the Patient Centered Outcomes Research Institute (PCORI), a non-profit organization chartered by Congress to fund projects to promote patient-centered care.
Safe Use of Heparin Sodium in Patients With Chronic Renal Failure.
Chronic Renal FailureThe Heparin form a complex with a plasma protein, antithrombin III (ATIII), which is an endogenous anticoagulant. This complex inhibits the formation of thrombin and accelerates its destruction. Moreover, heparin and other proteases ATIII inactivate the clotting cascade, especially the anti-activated factor X. The end result of these actions is the inhibition of biochemical training and synthesis of certain clotting factors that activators of critical functions in the genesis of a blood clot. Patients with chronic renal failure (CRF) who use the treatment of hemodialysis need a system of anticoagulation with the direct thrombin inhibitor and / or heparinóides to prevent thrombosis. Based on clinical studies, to control the level of plasma heparin in patients with CRF is essential. Evidence of clotting as APTT, TP, ACT and proof of the activity of anti-factor Xa should be used as a substrate of protection for those patients on hemodialysis.
Evaluation of Daily Hemodialysis With Low Dialysate Flux in Unscheduled Patients With Kidney Injury...
Acute Kidney InjuryKidney Failure1 moreThe objective of the EQUODIA study is to evaluate the hemodynamic stability of hemodialysis with low dialysate flow in patients requiring emergency hemodialysis in the context of acute kidney injury or unscheduled end-stage renal disease, not in intensive care, compared to conventional triweekly high-flow hemodialysis. Short daily hemodialysis has excellent hemodynamic tolerance, which has already been confirmed by clinical experience. This modality, commonly used in the patient's home through new machines allowing a low dialysate flow purification technique, can prove to be an innovative, effective and safe alternative for patients admitted for hemodialysis in an unscheduled situation (acute kidney injury, unscheduled end-stage renal disease not followed). Up to now, no studies have evaluated the use of short daily hemodialysis with low dialysate flow in patients with acute kidney injury or unscheduled end-stage renal disease, requiring the initiation of emergency extra-renal purification.

EuroSIDA - Clinical and Virological Outcome of European Patients Infected With HIV
HIVHepatitis B14 moreThe EuroSIDA study is a prospective observational cohort study of 23,000+ patients followed in 100+ clinics in 35 European countries, Israel and Argentina. The study is the largest pan-European cohort study and few studies of a comparable design are available on a global scale. The EuroSIDA study is an ongoing collaboration and patients have been enrolled into the study through 11 cohorts since 1994. The main objective of the study remains the same as in 1994: to prospectively study, clinical, therapeutic, demographic, virological and laboratory data from HIV-1 positive persons across Europe in order to determine their long-term virological, immunological and clinical outcomes. Historically, EuroSIDA has been crucial in reporting key changes in the HIV epidemic, such as the dramatic changes in morbidity and mortality when combination anti-retroviral therapy (cART) was first introduced. As new anti-HCV treatment is introduced to HIV/HCV co-infected patients, it is important for EuroSIDA to remain in the forefront of investigating the treatment benefits and adverse effects. All study documents, study status, newsletters, scientific publications and presentations are available online and are updated continuously at project website. In general terms, the objective of the EuroSIDA study is to continue a long-term, prospective collection of clinical, laboratory and therapeutic data as well as plasma on a large cohort of consecutive HIV infected patients from across Europe in order to (1) assess the factors associated with the clinical, immunological and virological course of HIV infection and HIV-related co-infections and co-morbidities, and (2) continue to provide and develop a surveillance system to describe temporal changes and regional differences in the clinical course of HIV and HIV-related co-infections and co-morbidities in Europe.
External Validation of the VExUS Score for the Prediction of Acute Renal Failure in Cardiac Surgery...
Renal FailureAcute Renal Failure2 moreAcute 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.
Vascular Calcifications in Kidney Transplant Recipient
Arterial CalcificationKidney Failure1 moreKidney transplant candidates undergo extensive diagnostic evaluation aimed at assessing their cardiovascular (CV) risk, which remains the leading cause of disability and death in this patient population. This includes among others an assessment of the iliac arterial calcification. Chronic kidney disease (CKD) patients have an increased incidence of arterial calcifications due to many factors, such as increased age, hyperparathyroidism, diabetes mellitus and hypercholesterolemia. Furthermore, the severity of pelvic arterial calcifications may impact the surgical planning of kidney transplantation (KT), choice of anastomosis site, complexity of the surgery, and patient and graft survival. Vascular calcifications are recognized as a good biomarker of overall cardiovascular burden. Although computerized tomography (CT) is the imaging modality of choice for calcification evaluation, compared to pelvic X-ray and Doppler ultrasound, it is not officially included in the guidelines of different international associations, which offer general recommendations for the assessment of iliac vessels. Nevertheless, centers are increasingly using CT in their pretransplant workup, either routinely or only in patients with increased CV risk. Also, impaired bone metabolism and its consequences have an important role in the development of vascular calcification. The investigators will determine the relationship between calcification burden of iliac arteries which will be assessed on CT and the serum level of bone remodeling biomarkers, including parathyroid hormone, (PTH), calcium, phosphates, OPG/RANK/RANKL (engl. osteoprotegerin/receptor activator of nuclear factor (NF)-κΒ/RANK ligand) and Gla-Rich protein (GLP). According to investigator knowledge, this will be the first prospective study that will correlate the degree of iliac arteries calcification based on CT analyses with the serum level of various bone remodeling markers, and their impact on clinical outcome in kidney transplant recipients. The investigators expect this research to improve insights into incidence and distribution of iliac artery calcifications in patients following kidney transplantation, their correlation with clinical data and bone remodeling markers and confirm the appropriateness of using computerized tomography in a routine pretransplantation work-up.
Renal Replacement Therapy in Neonates
Renal FailureThe circumstances for setting up dialysis in the neonatal period are multiple: congenital anomaly of the kidney and urinary tract (CAKUT), secondary acute renal failure whose etiologies are multiple (sepsis, hypovolemia, respiratory distress syndrome, neonatal asphyxia, Arterial or venous renal thrombosis, nephrotoxic drugs, etc.), metabolic diseases (mainly hyperammonemia and leucinosis) and post-operative management of heart disease: analysis of the characteristics of the patients in our study and comparison with existing epidemiological data in the literature. The decision to set up dialysis in a newborn whose recovery of renal function is uncertain or in a context of acute multi-visceral failure is not always obvious and must be discussed carefully. multidisciplinary in connection with neonatologists, resuscitators and nephrologists as well as families with the consideration of the future quality of life of the child.
