Non-invasive Determination of Anemia in Children With Renal Failure
Renal FailureAnemia and inflammation are very common in patients with renal diseases. The most common procedure to detect anemia is to determine blood hemoglobin concentrations. The Haemospect® is a portable device for non-invasive hemoglobin determination that works with a sensor that is applicable in infants and adults alike. The objective of this trial is to collect spectra with the non-invasive Haemospect® device in children of different age groups with renal failure and different hemoglobin concentrations. In parallel, corresponding hemoglobin values shall be obtained invasively to form the basis for the development of an algorithm for the device. To determine inflammation, the frequencies of vasomotion and oxygenation of the tissue are measured non-invasively with the Haemospect®. Various blood parameters for iron and inflammation will also be determined, such as ferritin, hepcidin, transferrin, serum iron, white blood cell count and CRP.
Effects of Obesity Surgery on Renal Function
Impaired Renal FunctionIncreasing risk of impaired renal function as a result of obesity is well known. Early data has postulated that weight loss might improve kidney function, but the evidence is rather limited due to the difficulties in measuring glomerular filtration rate(GFR) after weight loss. Cystatin C, GFR measurement using Cockcroft-Gault (CCG) and Modification of Diet in Renal Disease (MDRD) equations, have all yield conflicting results after weight loss surgery. The study aim to assess: use of 51Cr-EDTA Clearance as the methodological gold standard in evaluating changes in renal function before and after weight loss surgery. the reliability of using MDRD, CCG and Cystatin C in measuring GFR after weight loss surgery the differences in alterations in renal function dependent on the surgical procedures( gastric bypass, gastric band, sleeve gastrectomy). the use of urine albumin/creatinine ratio in detecting alterations in microalbuminuria.
Inferior Vena Cava (IVC) Size in Acute Renal Failure
Acute Renal FailureBedside ultrasonographic assessment of IVC size and IVC collapsibility index can be used to guide the management of patients with acute kidney injury with and without volume overload in the intensive care unit
Health Related Quality of Life and Cognitive Function Among Norwegian Dialysis Patients
Chronic Kidney FailureRenal DialysisThe purpose of this study is to assess health related quality of life and its predictors among chronic dialysis patients and to assess cognitive function using 3 different tests. (undergraduate medical student research project; not published)
Evaluation of the Risk of Nephrogenic Systemic Fibrosis (NSF) in Patients With Chronic Kidney Disease...
Renal InsufficiencyThe objective of this long term study is to prospectively evaluate the incidence of NSF in patients with severe CKD or kidney failure including patients undergoing dialysis (stages 4 and 5 i.e., with an eGFR below 30)who have not had exposure to a GBCA within 10 years prior to enrollment.
Fanconi Syndrome Due to ARVs in HIV-Infected Persons
HIV InfectionsFanconi Syndrome2 moreCross-sectional cohort study of participants with HIV with or without protocol-defined Fanconi syndrome (confirmed creatinine clearance [CLcr] decline and evidence of proximal tubulopathy).
Evaluation of the Risk of NSF Following MultiHance Injection in Patients With Chronic Kidney Disease...
Renal InsufficiencyThe objective of this long-term study is to prospectively compare the incidence of NSF in two cohorts (Cohort 1 - patients with moderate chronic kidney disease eGFR 30 to 59 and Cohort 2 - patients with severe chronic kidney disease or kidney failure eGFR <30).
Non Invasive External Monitoring in Dialysis Patients
Kidney FailureThis is a single center, non randomized study to gather data to correlate physiological signals with the patient's fluid status during fluid removal in hemodialysis.

The Role of Endothelium Dysfunction in Progression of CKD (Chronic Kidney Disease) After AKI (Acute...
Acute Renal FailureChronic Kidney Failure2 moreTo understand how AKI (Acute Kidney Injury) leads to chronic kidney disease so therapies can be found to alter the progression of events thereby significantly impacting the long-term outcomes of children who develop AKI.
