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 a total of 25 conditions (21 IEMs). Between 1 March 2012 and 29 February 2020, 461,369 newborns were screened for 20 IEMs in addition to phenylketonur...

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 transplantation (Rtx) and in children with chronic kidney disease (CKD) and its associations to cardiovascular risk factors. In this cross-sectional study,...

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 24-hour sampling is required for accurate results. The primary aim of this study was to develop an iohexol pharmacokinetic population model for accur...

BAKGRUNN Doparesponsiv dystoni er en gruppe sykdommer som gir endrede nivåer av nevrotransmittere. Dette kan behandles med god effekt. Økt innsikt i patofysiologiske årsaksforhold har bedret forståelsen av sykdommene. KUNNSKAPSGRUNNLAG Artikkelen bygger på 39 artikler fra et systematisk søk i databasen Medline, to nettsteder og en lærebok. RESU...

Background Glomerular 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 equations with measured GFR (mGFR) by iohexol clearance in a cohort of children with chronic kidney disease (CKD). Methods We examined 96 children (...
Article
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 transplant recipients (KTR). The primary aim of this study was to evaluate different creatinine based equations in stable elderly KTR. A national cross-section...

Full-text available
Background: The 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 limiting the number of blood-draws in this patient population is especially relevant. We have performed a study to evaluate different formulas for calculating meas...
Article
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 published equations commonly used for GFR estimation in these patients. Methods. Adult kidney recipients (n = 594) were included, and blood samples we...

Full-text available
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 markers in blood and urine—guanidinoacetate (GAA), creatine (CRE), human epididymis protein 4 (HE4), and neutrophil gelatinase–associated lipocalin (N...
Article
Full-text available
Background: In 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. The aim of this study was to evaluate different formulas and determine the optimal sampling points for calculating mGFR based on iohexol clearance me...
Article
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 the blood volume. The purpose of the study was to validate a blood spot method for measuring GFR in children aged 6 years or younger suffering from c...
