Active clinical trials for "Acute Kidney Injury"

The aim of this study is to evaluate the rate and outcomes of COVID-19 associated acute kidney injury (AKI) and use of kidney replacement therapy (KRT) in critically ill COVID-19 patients in ICUs in several large hospitals in Flanders, the northern region of Belgium. We will also explore the associations between several baseline risk factors for AKI, therapeutic strategies and COVID-19 related clinical signs and the occurrence of AKI and use of KRT.

The first presentations of patients with acute kidney injury (AKI) are usually to the emergency departments. While the mortality rate is 5-10% in uncomplicated AKI, it is between 40-90% in patients hospitalized in the intensive care unit. Therefore early diagnosis and treatment of AKI in the emergency department is important in terms of morbidity and mortality. Sonographic evaluation of the venous system (hepatic, portal and renal vein) may be useful for diagnosis. Studies conducted so far have generally been based on predicting cardiorenal AKI and renal poor outcomes and have been designed in general ICU conditions. In this study, the investigators aimed to determine the diagnostic value of sonographic venous Doppler imaging in terms of distinguishing subgroups of AKI in patients presented to the emergency department with AKI.

Acute kidney injury (AKI) is a severe complication after liver resection and is associated with morbidity and mortality. The incidence of postoperative AKI is significantly higher in elderly patients, especially in those with comorbidities. There is currently limited evidence on the incidence and associations of postoperative AKI in elderly patients following liver resection. This study will evaluate the incidence and associations of AKI in elderly patients after liver resection and its impact on postoperative mortality.

The perioperative approach adopted in a cohort of adult oncological patients undergoing major abdominal surgery will be described. In particular, the physician's attitude toward use of sCr for identification of patients at risk for PO-AKI will be described, as well as the patients who should be reassessed in the long term for progression toward CKD. The incidence and risk factors associated with PO-AKI and renal function deterioration within a year postoperatively will be also evaluated.

Hepatorenal syndrome is a life-threatening medical condition and a serious complication of advanced liver scarring (cirrhosis). It consists of a deterioration of the function of the kidneys caused by a severe alteration in the circulation (blood flow to the kidneys) due to liver cirrhosis. Only around half of the patients respond to treatment which consists of intravenous medication. Moreover, the adrenal glands, which are located on the kidneys, also suffer an alteration in the blood flow leading to deterioration in their function as well. Thus, these patients produced less cortisol than needed; this situation is called "relative adrenal insufficiency". Cortisol is an important hormone necessary in extreme situations such as severe diseases. This is a study which will assess the relationship between the presence of adrenal dysfunction and failure to treatment in patients with hepatorenal syndrome.

This study proposes to perform a pilot observational study looking at the doses of propofol used for the induction of general anesthesia and its association with the development of hypotension and AKI among elderly patients at YNHH.

The assessment of renal functional reserve (RFR) has been proposed for the risk stratification of patients undergoing potentially nephrotoxic procedures. The investigators hypothesized that there is a correlation between IRRIV and RFR under normal conditions. For this purpose, externally validation of IRRIV test is performed in a validation cohort of healthy subjects.

The study aims to explore the association of the novel urinary bio marker NGAL with the age of PRBCs(packed red blood cells) transfusion in critically ill patients.

Renal dysfunction is a major risk factor for poorer outcome after liver transplantation. Nevertheless, mechanisms of renal dysfunction in liver transplant recipients are not clearly understood. Calcineurin inhibitors are generally perceived as the most important cause; however the liver transplant procedure itself represents a major surgical / hemodynamic / inflammatory trauma that - on its own - can cause renal dysfunction. Creatinine and creatinine clearance are late markers of acute kidney injury and changes in these parameters occur only after substantial injury has already occurred. Even a stable creatinine does not exclude structural kidney damage. A series of new markers of tissue injury have been identified and have the potential to identify acute kidney injury better and earlier than creatinine and creatinine clearance. The aim of this study is to determine whether and how liver transplantation affects these urinary and plasma biomarkers and to study whether the changes in these biomarkers may predict later changes in standard functional parameters (creatinine and creatinine clearance). For this purpose, the urinary and plasma biomarkers, together with creatinine, will be determined serially during the different phases of the liver transplant process and daily until day 5 after transplantation.

The purpose of this study is to compare the incidence of hospitalization for acute kidney injury among patients with type 2 diabetes who are new initiators of Saxagliptin and those who are new initiators of other oral antidiabetic drugs in classes other than Dipeptidyl peptidase IV (DPP4) inhibitors.
