OBJECTIVE Low muscle mass often indicates poor health, but the relation with cardiovascular disease (CVD) is unknown. Skeletal muscles are responsible for approximately 75% of insulin stimulated whole body glucose disposal and therefore insulin resistance could underlie the relation between muscle mass and CVD. We aimed to determine whether muscle mass, as(More)
BACKGROUND Chronic transplant dysfunction is characterized by renal function decline and proteinuria. Kidney injury molecule (KIM)-1, a transmembrane tubular protein with unknown function, is undetectable in normal kidneys, but markedly induced after injury. Urinary KIM-1 excretion has been quantified as biomarker of renal damage. We prospectively studied(More)
BACKGROUND Insulin resistance has been implicated to underlie both excess cardiovascular disease and chronic transplant dysfunction after renal transplantation. Skeletal muscle mainly determines peripheral insulin resistance, and could therefore affect outcome. METHODS All transplant recipients at our outpatient clinic with a functioning graft more than 1(More)
Diabetes is a stronger risk factor for cardiovascular disease (CVD) in women than in men. It is not known whether there is also a sex difference in the association between hyperinsulinaemia, reflecting insulin resistance, and CVD. Fasting insulin was assessed with a specific assay in 6916 fasting, non-diabetic subjects of the PREVEND study without a prior(More)
BACKGROUND Skin-autofluorescence (skin-AF) noninvasively measures the tissue accumulation of advanced glycation end products (AGEs). AGEs are nephrotoxic and potential effectors of cardiovascular mortality. We investigated whether skin-AF predicted graft loss after kidney transplantation. METHODS A total of 302 renal transplant recipients were enrolled at(More)
BACKGROUND The worldwide increase in end-stage renal disease has been alleged to be associated with insulin resistance-related conditions. Insulin resistance and the concomitant compensatory hyperinsulinaemia may accelerate age-related decline in renal function through inducing glomerular hyperfiltration, even in non-diabetic subjects. This population-based(More)
BACKGROUND Insulin resistance is considered to play an important role in the development of cardiovascular disease, which limits long-term renal transplant survival. Renal transplant recipients are more insulin-resistant compared with healthy controls. It is not known to date which factors relate to this excess insulin resistance. Therefore, we investigated(More)
BACKGROUND C-reactive protein (CRP) is a predictor of coronary heart disease, total mortality and chronic allograft nephropathy in renal transplant recipients. The determinants of CRP have been investigated in the general population, but not in renal transplant recipients. CRP might reflect metabolic aberrations in association with central obesity and(More)
OBJECTIVE The purpose of this study was to investigate the validity of established insulin resistance indexes, based on fasting blood parameters, in a stable renal transplant population. RESEARCH DESIGN AND METHODS Fasting insulin, homeostasis model assessment (HOMA), the quantitative insulin sensitivity check index (QUICKI), and McAuley's index were(More)
BACKGROUND Proteinuria is associated with endothelial dysfunction (ED) and increased mortality. We investigated whether urinary protein excretion (UPE) is correlated with markers of ED and whether these markers affect the association of proteinuria with mortality in renal transplant recipients (RTR). METHODS Six hundred four RTR with a functioning graft(More)
