Hyperglucagonaemia is a characteristic of several clinical conditions (e.g. end-stage renal disease (ESRD), type 2 diabetes, obesity before and after Roux-en-Y gastric bypass (RYGB) and vagotomy with pyloroplasty), but the molecular nature of ‘immunoreactive’ glucagon is poorly characterised. The specific determination of fully processed, intact glucagon(More)
BACKGROUND The aim of this study is to investigate the effect of kidney transplantation on arterial function in relation to changes in glucose metabolism. METHODS Included were 40 kidney recipients (Tx group, age 38 ± 13 years) and 40 patients without known diabetes remaining on the waiting list for kidney transplantation (uraemic control group, age 47 ±(More)
CONTEXT The affect of the kidneys in elimination and degradation of intact incretin hormones and their truncated metabolites is unclear. OBJECTIVE To evaluate elimination and degradation of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) in patients with dialysis-dependent kidney failure. SETTING AND DESIGN Twelve(More)
Nondiabetic patients with end-stage renal disease (ESRD) have disturbed glucose metabolism, the underlying pathophysiology of which is unclear. To help elucidate this, we studied patients with ESRD and either normal or impaired glucose tolerance (10 each NGT or IGT, respectively) and 11 controls using an oral glucose tolerance test and an isoglycemic(More)
OBJECTIVE To evaluate parameters related to safety and efficacy of liraglutide in patients with type 2 diabetes and dialysis-dependent end-stage renal disease (ESRD). RESEARCH DESIGN AND METHODS Twenty-four patients with type 2 diabetes and ESRD and 23 control subjects with type 2 diabetes and normal kidney function were randomly allocated to 12 weeks of(More)
BACKGROUND Patients with end-stage renal disease (ESRD) have glucometabolic disturbances resulting in a high prevalence of prediabetes. The underlying pathophysiology remains unclear, but may prove important for the strategies employed to prevent progression to overt diabetes. Meal-induced release of the insulinotropic gut-derived incretin hormones and(More)
The role of plasma adiponectin (ADPN) in patients with impaired kidney function and following kidney transplantation (Tx) is debated. We aimed to: (i) determine whether pretransplant ADPN level is an independent risk factor for deterioration of glucose tolerance including development of new-onset diabetes mellitus after Tx, (ii) describe which parameters(More)
BACKGROUND Anti-glomerular basement membrane glomerulonephritis and thrombotic microangiopathy are rare diseases with no known coherence. CASE PRESENTATION A daughter and her biological mother were diagnosed with pregnancy-induced thrombotic microangiopathy and anti-glomerular basement membrane glomerulonephritis, respectively. Both developed end-stage(More)
INTRODUCTION Diabetes is the leading cause of end-stage renal disease (ESRD). Owing to renal clearance, several antidiabetic agents cannot be used in patients with ESRD. The present protocol describes an investigator-initiated trial aiming to test safety and efficacy of treatment with the glucagon-like peptide-1 receptor agonist liraglutide in patients with(More)
BACKGROUND Patients with end-stage renal disease (ESRD) have increased fasting concentrations and disturbed postprandial responses of several glucoregulatory hormones. We aimed to evaluate the impact of high-flux haemodialysis (HD) and high-volume haemodiafiltration (HDF) on fasting and postprandial plasma levels of glucoregulatory pancreatic and gut(More)
