Growth Differentiation Factor 15 in Children with Chronic Kidney Disease and after Renal Transplantation
- Hjørdis Thorsteinsdottir, Cathrin L Salvador, +6 authors A. Bjerre
- Medicine
- Disease markers
- 6 February 2020
Growth differentiation factor 15 (GDF-15) is strongly associated with cardiovascular disease (CVD). The aim of our study was to evaluate plasma and urinary levels of GDF-15 after pediatric renal… Expand
Iohexol plasma clearance in children: validation of multiple formulas and two-point sampling times
BackgroundIn children, estimated glomerular filtration rate (eGFR) methods are hampered by inaccuracy, hence there is an obvious need for safe, simplified, and accurate measured GFR (mGFR) methods.… Expand
Glomerular filtration rate measured by iohexol clearance: A comparison of venous samples and capillary blood spots
- Cathrin L Salvador, C. Tøndel, +5 authors S. Bergan
- Chemistry, Medicine
- Scandinavian journal of clinical and laboratory…
- 1 October 2015
Background. Glomerular filtration rate (GFR) measured by iohexol clearance using venous samples is widely used. Capillary sampling on filter paper is easier to perform, may be less painful and spares… Expand
Estimating Glomerular Filtration Rate in Kidney Transplant Recipients: Comparing a Novel Equation With Commonly Used Equations in this Population
- Cathrin L Salvador, A. Hartmann, A. Åsberg, S. Bergan, A. Rowe, L. Mørkrid
- Medicine
- Transplantation direct
- 8 November 2017
Background Assessment of glomerular filtration rate (GFR) is important in kidney transplantation. The aim was to develop a kidney transplant specific equation for estimating GFR and evaluate against… Expand
Estimated glomerular filtration rate in stable older kidney transplant recipients—are present algorithms valid? A national cross‐sectional cohort study
- K. Heldal, K. Midtvedt, +5 authors A. Åsberg
- Medicine
- Transplant international : official journal of…
- 1 June 2018
Several equations have been developed for estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD), but none were developed based on data from elderly kidney… Expand
Estimating glomerular filtration rate in children: evaluation of creatinine- and cystatin C-based equations
- Cathrin L Salvador, C. Tøndel, +4 authors L. Mørkrid
- Medicine
- Pediatric Nephrology
- 1 February 2019
BackgroundGlomerular filtration rate (GFR) estimated by creatinine- and/or cystatin C-based equations (eGFR) is widely used in daily practice. The purpose of our study was to compare new and old eGFR… Expand
Renal Function Influences Diagnostic Markers in Serum and Urine: A Study of Guanidinoacetate, Creatine, Human Epididymis Protein 4, and Neutrophil Gelatinase–Associated Lipocalin in Children
- Cathrin L Salvador, C. Tøndel, +5 authors L. Mørkrid
- Chemistry
- 1 November 2017
Background: Impaired renal function may affect the level of diagnostic disease markers. The aim of the study was to investigate the effect of measured glomerular filtration rate (GFR) on 4 diagnostic… Expand
Iohexol plasma clearance in children: validation of multiple formulas and single-point sampling times
- C. Tøndel, Cathrin L Salvador, +5 authors A. Brun
- Medicine
- Pediatric Nephrology
- 13 November 2017
AbstractBackgroundThe non-ionic agent iohexol is increasingly used as the marker of choice for glomerular filtration rate (GFR) measurement. Estimates of GFR in children have low accuracy and… Expand
Measured GFR by Utilizing Population Pharmacokinetic Methods to Determine Iohexol Clearance
Introduction There is an increasing demand for accurately measured glomerular filtration rate (GFR). Iohexol serum clearance has become a new gold standard, but it is challenging when GFR is low and… Expand
Performance of Expanded Newborn Screening in Norway Supported by Post-Analytical Bioinformatics Tools and Rapid Second-Tier DNA Analyses
- T. Tangeraas, Ingjerd Sæves, +30 authors R. Pettersen
- Medicine
- International journal of neonatal screening
- 27 June 2020
In 2012, the Norwegian newborn screening program (NBS) was expanded (eNBS) from screening for two diseases to that for 23 diseases (20 inborn errors of metabolism, IEMs) and again in 2018, to include… Expand
