Active clinical trials for "Acute Kidney Injury"

New biomarkers that predict the development of renal dysfunction in patients with aortic surgery are urgently needed. The investigators investigate whether urinary (TIMP-2)x(IGFBP7) predicts postoperative Acute Kidney Injury and/or need for Renal Replacement Therapy (RRT) in patients after aortic surgery (including EVAR).

The investigators aimed to evaluate the association between the duration and stage of acute kidney injury (AKI) and the development of chronic kidney disease during postoperative three years in patients undergoing cardiac or thoracic aortic surgery.

The incidence of acute kidney injury (AKI) postoperatively has been identified to be 21.6% in adults and 18.3% in hospitalized individuals. Surgery-related AKI is a severe complication that is related not only to short-term complications as increases in mortality rate and development of cardiac complications but also with complications on long term, such as development of chronic kidney disease. A better understanding of the mechanism of this hypthesis will lead to better management of this complication.

Background. Within a year, COVID-19 has advanced from being an outbreak to a pandemic, spreading rapidly and globally with devastating impact. Currently, there is an ongoing debate among scientists about the pathophysiological relationship between COVID-19 and acute kidney injury (AKI). While a few studies have concluded that the mechanisms of AKI in COVID-19 patients are seemingly multifactorial and have not been fully explicated, others asserted that AKI remains rare among COVID-19-related diseases. Considering this knowledge-gap and its potential impact on the management of COVID-19-associated AKI, our study aims to explore the prevalence of AKI and to identify possible risk factors associated with AKI development among COVID-19 hospitalized patients. Materials and Methods. This retrospective cohort study included 83 patients with COVID-19 hospitalized at AL-AHRAR Hospital, Zagazig, Egypt, between June and August,2020. Exclusion criteria were: patients younger than 18 years of age; diagnosed with end stage kidney disease; placed on maintenance dialysis; booked for a kidney transplant or on nephrotoxic medications. All patients included in the study underwent complete blood count; liver and renal function tests; examination of hemostasis parameters; inflammatory markers; serum electrolytes; routine urinalysis; arterial blood gas and non-enhanced chest and abdominal computer tomography (CT) scans

In Kuwait, the total number of COVID-19 confirmed cases exceeds 5000 patients. Risk factors of possible risk factors of confirmed COVID-19 infection that developed major organ dysfunction are not yet identified among patients in Kuwait. we aimed to describe the clinical characteristics of hospitalized symptomatic COVID-19 positive patients, assess possible risk factors of confirmed COVID-19 infection who developed major organ dysfunction, determine risk factors for renal dysfunction and their outcome and assess the response of critically ill patients to different therapeutic modalities.

Acute kidney injury (AKI) affects up to 30% of critically ill patients and is associated with increased rates of mortality. Up to 60% of patients with AKI will ultimately require renal replacement therapy (RRT). Intermittent hemodialysis (IHD) is one of the main methods of RRT worldwide. In IHD-bicar, dialysate is composed by electrolytes, including calcium, and bicarbonate. To avoid calcium carbonate precipitation, dialysate has to be supplemented with acids (citric acid, chloride acid or acetic acid). However, IHD-bicar may be associated with hemodynamic instability or respiratory intolerance, mainly related to the CO2 release in the circulation during IHD (HCO3- <--> CO2 + H2O). Some recent studies showed that acetate free biofiltration (AFB-K), a technique that does not require dialysate acidification, could be associated with better hemodynamic stability and to a lower amount of CO2 delivered to the patients. AFB-K may thus improve the hemodynamic and respiratory tolerance of intermittent RRT in critically ill patients.

In addition to respiratory involvement, SARS-CoV 2, the virus responsible for coronavirus 2019 or Covid-19, appears to be responsible for renal involvement such as acute renal failure or proteinuria, so the mechanisms are not known at this time. The consequences of Covid-19 on renal function in the short and long term are not known. It is important to be able to better document these renal impairments to understand the mechanisms of this disease. The main objective of this study is to describe the prevalence of Covid-19-related renal damage (acute renal failure, proteinuria, microalbuminuria, hematuria) in a large cohort of patients in intensive care for SARS-CoV 2 infection with severe respiratory impairment. The other objectives will be to evaluate in this cohort the impact of these renal impairments on the severity of the Covid-19 disease, and to compare them to the renal impairments of patients in intensive care for acute respiratory distress syndrome (ARDS) due to other respiratory diseases. Blood and urine samples will be taken at the time of intubation in all critically ill patients with respiratory distress requiring mechanical ventilation for Covid-19 or other cause of respiratory distress with PaO2/FiO2 ratio < 300. Patients will be followed for the duration of their ICU and hospital stay. Data will be collected prospectively in three ICUs in the University Hospitals of Marseille.

A retrospective study evaluating AKI patients in whom RRT was interrupted for at least 48 hours. Patients who were still RRT-independent 7 days after initial RRT cessation were included in the "Success" group, as opposed to the "Failure" group. Baseline characteristics and variables at the time of RRT interruption were collected. Multivariable analysis was performed and a model was generated to evaluate the prediction of success.

Patients with sickle cell disease may be at risk for acute kidney injury (AKI)during sickle cell crisis (pain or acute chest syndrome). This study will evaluate the role of hemolysis during SCD crisis on the development of AKI and the role for monitoring urine biomarkers during an admission for crisis and during well clinic follow-up.

Acute kidney injury (AKI) occurs in approximately one-third of patients undergoing cardiac surgery (CS), and represents one of the most significant negative predictors of patient outcome in this population. The investigators sought to examine the risk factors associated with the development of AKI and renal recovery in patients undergoing cardiac surgery at San Bortolo Hospital, Italy 2014-2015.
