Blood pressure and age-related GFR decline in the general population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-28)Background: <br> Hypertension is one of the most important causes of end-stage renal disease, but it is unclear whether elevated blood pressure (BP) also accelerates the gradual decline in the glomerular filtration rate (GFR) seen in the general population with increasing age. The reason may be that most studies have considered only baseline BP and not the effects of changes in BP, antihypertensive ... -
Central obesity associates with renal hyperfiltration in the non-diabetic general population: a cross-sectional study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-10)<p><i>Background - </i>Obesity is a risk factor for end-stage renal disease. Renal hyperfiltration, defined as an abnormally high glomerular filtration rate (GFR), is a link in the causal chain between diabetes and chronic kidney disease. Whether obesity is associated with hyperfiltration in the non-diabetic general population, remains unresolved due to a lack of consensus regarding the definition ... -
Correlation between baseline GFR and subsequent change in GFR in Norwegian adults without diabetes and in Pima Indians
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-28)<p><i>Rationale & Objective - </i>An elevated glomerular filtration rate (GFR), or renal hyperfiltration, may predispose individuals to subsequent rapid GFR decline in diabetes, obesity, and metabolic syndrome. Although this hypothesis is supported by results of experimental studies, the importance of hyperfiltration at the population level remains controversial. We investigated whether higher ... -
Elevated blood pressure is not associated with accelerated glomerular filtration rate decline in the general non-diabetic middle-aged population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-14)Although hypertension is a risk factor for end-stage renal disease, this complication develops in only a minority of hypertensive patients. Whether non-malignant hypertension itself is sufficient to cause reduced glomerular filtration rate (GFR) is unclear. We investigated whether elevated blood pressure (BP) was associated with accelerated GFR decline in the general population. The study ... -
Estimated GFR is biased by non-traditional cardiovascular risk factors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-23)Background: Estimated glomerular filtration rate (eGFR) based on either cystatin C or creatinine perform similarly in estimating measured GFR, but associate differently with cardiovascular disease (CVD) and mortality. This could be due to confounding by non-GFRrelated traits associated with cystatin C and creatinine levels. We investigated non-GFRrelated associations between eGFR and two types ... -
Mild Albuminuria Is a Risk Factor for Faster GFR Decline in the Nondiabetic Population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-08)<i>Introduction</i>: A minimal increase in the albumin-to-creatinine ratio (ACR) predicts cardiovascular disease and mortality, but whether it predicts kidney function loss in nondiabetic persons is unclear. We investigated the association between ACR in the optimal or high-normal range and the rate of glomerular filtration rate (GFR) decline in a cohort from the general population without diabetes, ... -
Oxidative stress and inflammation as risk factors for accelerated age-related GFR decline and albuminuria in the general population
(Doctoral thesis; Doktorgradsavhandling, 2018-06-08)The prevalence of chronic kidney disease (CKD) increases rapidly with age, affecting more than one-third of people over 70 years old. The age-related glomerular filtration rate (GFR) decline is an important risk factor for CKD and kidney failure. Identifying novel risk factors for early kidney disease, manifested as accelerated GFR decline or low-grade albuminuria, may suggest underlying pathologic ... -
Prediabetes and Risk of Glomerular Hyperfiltration and Albuminuria in the General Nondiabetic Population: A Prospective Cohort Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-29) -
Prediabetes and Risk of Glomerular Hyperfiltration and Albuminuria in the General Nondiabetic Population: A Prospective Cohort Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-29)Background: The role of prediabetes as a risk factor for hyperfiltration and albuminuria in persons who do not develop diabetes is unclear. The lack of evidence is mainly due to the difficulty of accurately assessing the glomerular filtration rate (GFR) in the near-normal range of GFR. We investigated whether prediabetes is an independent risk factor for glomerular hyperfiltration and high-normal ... -
Urinary Markers of Oxidative Stress Are Associated With Albuminuria But Not GFR Decline
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-07)<p><i>Introduction</i>: Markers of oxidative stress increase with age and are prevalent with chronic kidney disease. However, the role of oxidative stress markers as predictors for kidney function decline in the general population is unclear.</p> <p><i>Methods</i>: We investigated whether a baseline urinary excretion of oxidative DNA damage (8-oxo-7,8-dihydro-2′-deoxyguanosine [8-oxodG]) and ...
