Implementation of CRRT KPI Reports to Standardize and Improve the Quality of CRRT Delivery in Alberta...

Critical IllnessAcute Kidney Failure

Acute kidney replacement therapy (i.e., dialysis) is used in 6-10% of patients admitted to intensive care units (ICUs). The amount of acute kidney replacement therapy use has increased in Canadian ICUs over the last several years. Continuous renal replacement therapy (CRRT) remains the most common form of acute renal replacement therapy used in ICUs. Many different parts aspects of CRRT lack a usual way to be done, and because of this, are done differently in different ICUs. Not having generally accepted markers of the performance and delivery of CRRT is a main reason that we have these practice difference. This is an important gap in the way that clinicians deliver this important ICU therapy and is a main focus of ongoing research in ICU and dialysis. The proposed project is a continuation of a program of work that first reviewed the current state of the quality and safety in ICU and dialysis. Then, a systematic review of all potential quality markers was done to see what options for measures were possible. Next, following a meeting of leaders of dialysis in the ICU, the most important of these measures were ranked to decide which ones could be used in monitoring CRRT for patients.

Acute Kidney FailureAcute Kidney Insufficiency17 more

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.

Outcome of Patients Treated With RRT

Acute Kidney InjuryCardiac Surgery

Acute Kidney Injury (AKI) is a common serious complication after cardiac surgery. AKI not only prolongs the hospitalization time of patients undergoing cardiac surgery and increases the cost of treatment, but also is an independent risk factor for postoperative death. The aim of this study is to investigate the outcome of patients treated with renal replacement therapy (RRT), and to evaluate the short-term and long-term outcomes of patients with RRT.

Inflammatory Mediators of Acute Kidney Injury in Intensive Care

SepsisSurgery1 more

Acute kidney injury (AKI) affects more than 50% of patients admitted to the intensive care unit. The most common underlying cause is sepsis. Severe AKI in combination with sepsis is associated with high mortality. The mechanisms for sepsis-induced AKI are largely unknown. Our hypothesis is that the inflammatory response to an infection cause collateral damage to host tissue and contributes to the development of AKI. In this study we want to investigate the presence of novel inflammatory mediators in patients with sepsis, patients subjected to major surgery (sterile inflammation) and non-inflamed patients and correlate their levels with the risk for AKI.

Graft Acute Kidney Injury: Vitamin B3 to Facilitate Renal Recovery In the Early Life of a Transplant...

Delayed Graft Function

Delayed graft function occurs in more than 20% of kidney transplantations. It is an episode of post-ischemic acute kidney injury with long-term consequences on the allograft's function. Based on preclinical data and on a stage 1 clinical trial, the hypothesize is that an acquired defect in NAD+ biosynthesis is instrumental in delayed graft function and that a treatment with high doses of vitamin B3 (nicotinamide) will improve the early renal graft function. Thus, it is planned to recruit 204 kidney allograft recipients immediately before transplantation and randomize them to either placebo or nicotinamide treatment for 3 administrations before transplantation, immediately after it and on the next day. The efficacy of nicotinamide to foster early graft function will be evaluated by comparing the creatinine reduction ratio between the placebo and the nicotinamide treated groups. Serum will be collected before and 2 days after transplantation and urine 2 days and 3 months after transplantation to study the relationship between biological markers of NAD+ biosynthesis and nicotinamide's effect on early kidney graft function.

Extracorporeal Blood Purification Therapy in Critically Ill Patients (GlobalARRT)

Critical IllnessAcute Kidney Injury2 more

Worldwide, the use of Extracorporeal Blood Purification (EBP) in everyday clinical practice is becoming increasingly common, particularly in critical care settings. The efficacy of most of these treatments on removal of inflammatory mediators is the main rationale behind the use of EBP in critically ill patients with multiorgan dysfunction. Nonetheless, there are still some doubts as to the clinical efficacy of bacterial toxins and cytokines removal and many clinical trials aiming at exploring the effect of EBP on long-term outcomes of septic patients have failed to demonstrate consistent results regarding 28 day- or hospital-mortality rates. The primary aim of this observational prospective web-based registry is to define the possible clusters of critically ill patients - treated with extracorporeal blood purification therapies worldwide - who are homogeneous regarding both clinical and treatment characteristics and seem to benefit the most from EBP.

RRT With a Cytokine Absorption Filter (oXiris ®) in Patients With Septic Shock

Acute Kidney InjurySeptic Shock

Acute kidney injury (AKI) is a common complication in critically ill patients. Multiple studies have reported evidence that the main cause of ARF is sepsis, as part of the Multiple Organ Dysfunction Syndrome: up to 50% of septic patients develop acute renal failure. RRT continues to be the standard management for severe acute renal failure, especially in its continuous modality and applied to the septic patient, generally with hemodynamic instability. The presence of SA-AKI (sepsis-associated acute kidney injury) is associated with short-term and long-term adverse events, which include: prolonged hospital stay, the development of chronic kidney disease (CKD), increased cardiovascular risk and increased risk of death. Its presence is even considered a factor with an independent association with mortality and has a higher fatality rate than ARF developed by another etiology. Different clinical studies have been developed based on the addition of hemoadsorption membranes to RRT that, although they have not shown significant differences in the reduction of mortality, have impacted secondary outcomes such as the reduction of pro-inflammatory cytokines, decrease in vasopressor support requirements, decrease in serum lactate, significant improvement in the SOFA score, improvement in oxygenation indices and decrease in hospital stay. These benefits are presented without reports of adverse events associated with its use. The oXiris® filter was recently developed: a single high permeability membrane capable of removing cytokines and endotoxins during renal support with the addition of antithrombotic properties. The experience of its use is limited to in vitro studies, case reports, retrospective cohorts and an RCT that provide consistent evidence of its benefits. A longitudinal, bi-directional, observational analytical study is proposed. A case-control study nested in a dynamic cohort will be developed to determine the effect of the use of hemofiltration with a cytokine removal filter (oXiris®) on the decrease in mortality at 28 days of patients with acute kidney injury induced by sepsis. (SA-AKI), as well as the dose of vasopressor support, oxygenation parameters and inflammatory markers.

Neutrophil Gelatinase-associated Lipocalin in Major Abdominal Surgery

Acute Kidney Injury

Acute kidney injury (AKI) after major surgery is a well-known complication. The incidence of AKI after major surgery ranges from 13% to 50%. The morbidity and mortality rates increase in patients with AKI due to the treatments applied and the prolonged hospital stay. In addition, as a result of all these processes, hospital costs increase and burden the health systems. Classifications such as Acute Kidney Injury Network (AKIN) or Kidney Disease Improving Global Outcomes (KDIGO) are used in the diagnosis of AKI. In these classifications, evaluation is made based on kidney damage, serum creatinine (Scr), and urine output. However, Scr; is affected by factors such as age, gender, diet, muscle mass, and medication. In addition, in healthy individuals in terms of kidney reserve, a loss of up to 50% in nephrons is tolerated by the body and there is no change in Scr values. Therefore, the onset of the increase in Scr values occurs 48-72 hours after kidney damage. This situation causes delays in the treatments applied and increases morbidity and mortality rates. For these reasons, interest in biomarkers used in the early diagnosis of AKI has increased in recent years. Neutrophil gelatinase-associated lipocalin (NGAL) is a 25 KDa, neutrophil-derived molecule from the lipocalin family. It is also secreted in small amounts from kidney, prostate, and respiratory tract epithelial cells. After ischemic and nephrotoxic acute tubular necrosis, NGAL levels peak at the 3rd hour and remain elevated for approximately 24 hours. In patients who do not progress to AKI, NGAL levels begin to decrease in the 1st hour after injury. When the current literature is examined, scientific studies on NGAL have mostly been carried out on cardiovascular surgery cases to date. There are very few studies evaluating NGAL levels in patients who develop AKI after major abdominal surgery. These few studies evaluated either serum NGAL or urinary NGAL levels. In this study, both serum NGAL and urinary NGAL will be measured simultaneously to detect AKI that may develop in patients undergoing major abdominal surgery.
