To find out risk factors that relate with the prognosis of acute kidney injury,focusing on inflammation, oxidative stress and nutritional status. To study on the relationship between gene polymorphism and prognosis of acute kidney injury.
Data on the Prevention of Complications of Prophylactic Intravenous Hydration in Patients With eGFR...
Acute Kidney Injury (Nontraumatic)Contrast-induced NephropathyAt Maastricht University Medical Centre (Maastricht UMC+) a specialised unit was established where a dual screening process including both renal and cardiac parameters is used to minimize the risk of contrast-induced acute kidney injury as well as the risk of prophylactic hydration in eGFR<30mL/min/1.73m2 patients. Very little data exists on patients with eGFR <30mL/min/1.73m2 in this context. The current study aims to describe post-contrast outcomes of patients to whom this screening method has been applied.
Incidence, Risk Factors and Consequences of Acute Kidney Injury in Patients Undergoing Esophageal...
Acute Kidney InjuryPostoperative ComplicationsEsophagectomy serves as an exemplar of major operative trauma, with well-known risk of pulmonary, cardiac, anastomotic, and septic complications and the presence of postoperative complications after esophagectomies for cancer is associated with a reduced long-term survival. There is a paucity in the literature regarding postoperative renal outcomes after esophageal surgery, with a wide range of incidence. The investigators will conduct a historical cohort study aiming to evaluate the incidence of postoperative acute kidney injury in patients undergoing elective esophageal cancer surgery. Secondary, the investigators will assess the progression of the acute injury and the association with adverse pulmonary, cardiac, anastomotic, and septic events, as well as increase in hospital stay and mortality. The investigators will also identify risk factors associated with acute kidney injury occurrence.
Pediatric Acute Kidney Injury in COVID-19
Acute Kidney InjuryCOVIDThis study is an observational registry of children with or suspected to have SARS CoV2 (COVID-19) admitted to pediatric intensive care units (PICU). This registry will help describe the prevalence, rate and severity of acute kidney injury (AKI) in children with Severe Acute Respiratory Syndrome Coronavirus-2(SARS CoV2) across the world. The registry will be developed using a point prevalence methodology and then full retrospective review. Once a week, from April through June 2020, data collection will occur in "real-time" to estimate a weekly point prevalence of AKI and renal replacement therapy (RRT). The operational definition of "patients under investigation" (PUIs) will be used to identify the denominator of patients to be studied. The PUIs will be cohorted into SARS CoV2 test positive, test negative, test pending, or test unavailable. The primary aim of this study is to deliver a global, objective data driven analysis of the burden of AKI in virus positive patients or patients under investigation (PUI) who are admitted to the pediatric intensive care unit.
Prediction of Acute Kidney Injury in Patients With COVID-19
Acute Kidney InjuryCOVID-191 moreThe two biomarkers determined in urine, "Tissue Inhibitor of Metalloproteinases 2 (TIMP-2)" and "Insulin-like Growth Factor-Binding Protein 7 (IGFBP7)", can indicate the occurrence of Acute kidney injury (AKI) in cardiac surgery and critically ill patients at an early stage. However, no data are available whether these parameters can also predict the occurrence of AKI in the context of COVID-19 infection. An early prediction of AKI can be helpful for the optimisation of therapeutic management to improve patient outcome and for the triage of patients. The aim of this observational study is to evaluate whether the biomarker [TIMP- 2]*[IGFBP7] can predict the occurrence of AKI in critically ill patients suffering from SARS-CoV2 associated acute respiratory distress syndrome.
Urinary Biomarkers for AKI Diagnosis in Patients With SARS-CoV-2 (COVID-19)
COVID-19Renal Replacement Therapy1 moreAmong patients with SARS-CoV-2 pneumonia, approximately 20% have an acute kidney injury (AKI) and 5% require renal replacement therapy. Occurrence of AKI in patients with COVID-19 is associated with increased morbidity and mortality. Early detection of patients at risk of AKI would allow to prevent onset or worsening of AKI. The aim of this study is to determine if urine biomarkers of renal tubular damage such as TIMP-2 and IGFBP7 could early identify patients with SARS-CoV-2 pneumonia at risk of developing AKI.
Predictive Value of Doppler RSI for Prediction of AKI in Septic Patients in ICU
Acute Kidney InjurySepsisAcute kidney injury (AKI) Diagnosis is based on rising creatinine. Intrarenal vasoconstriction occurs earlier and measuring flow resistance in the renal circulation (Renal Resistive Index (RRI)) could become part of vital organ function assessment using Doppler ultrasound. The aim of this study is to predict AKI in septic patients in ICU by measuring RRI on admission by comparing two groups of patients, first group with RRI of normal value (0.6-0.7) and the other group with high RRI more than 0.7 and both with normal renal function on admission.
A Clinical Score to Predict Acute Kidney Injury After Heart Valve Replacement Surgery
Acute Kidney InjuryAcute kidney injury (AKI) is a common and severe complication of cardiac surgery. The main stay treatment remains preventive with no clear evidence supporting any therapeutic interventions. AKI risk prediction scores are an objective, transparent means of cohort enrichment but are not widely used. The purpose of this analysis was to develop and validate a clinical score including pre-,intra-and post-operative predictors that predicted AKI following heart valve replacement surgery. This prediction score allows identification of patients at high risk of AKI and may support decision-making for protective kidney treatment.
CI-AKI in Patients With Stable CAD and Comorbidities. Are we Doing Better?
Stable AnginaAcute Kidney Injury1 morePatients aged 18-89 with stable CAD and comorbidities receiving optimal medical treatment requiring PCI with iodinated contrast media. The aim of the study is to assess the prevalence of contrast-induced AKI in 2012-2013 and 2017 cohorts and to evaluate the potential risk factors of CI-AKI to better guide the prevention in patients of higher risk.
Urine Biomarkers to Predict Acute Kidney Injury After Pediatric Cardiac Surgery
Acute Kidney InjuryCongenital Cardiac DisordersThe goal of this prospective cohort study is to evaluate, in pediatric patients after cardiac surgery, the predicting capability of biomarkers for acute kidney injury. The main questions it aims to answer: The predicting capability of acute kidney injury (AKI) biomarkers for the primary endpoint: the occurrence of AKI stage ≥ 1 within 48-h after intensive care unit (ICU) admission. The predicting capability of AKI biomarkers for the secondary endpoint: the occurrence of AKI stage ≥ 2 within 12-h after ICU admission. Investigated biomarkers include urine chitinase 3-like protein 1 (uCHI3L1), urine neutrophil gelatinase-associated lipocalin (uNGAL), tissue inhibitor of metalloproteinases-2 (TIMP-2), insulin-like growth factor-binding protein 7(IGFBP7), NephroCheck® and Δ serum creatinine [postop-preop]. Differences in concentration between patients with and without AKI development were investigated, as well as AKI diagnostic performance of (combined) biomarkers. During and after cardiac surgery several blood and urine samples will be taken of participants to investigated AKI occurrence and to measure biomarker concentrations.
