Identification of genetic risk factors for albuminuria may alter strategies for early prevention of CKD progression, particularly among patients with diabetes. Little is known about the influence of common genetic variants on albuminuria in both general and diabetic populations. We performed a meta-analysis of data from 63,153 individuals of European(More)
BACKGROUND Although previous studies suggest similar patient survival for peritoneal dialysis (PD) and haemodialysis (HD), PD use has decreased worldwide. We aimed to study trends in the choice of first dialysis modality and relate these to variation in patient and technique survival and kidney transplant rates in Europe over the last 20 years. METHODS We(More)
BACKGROUND The aim of this study was to evaluate the clinical course of patients with Wegener's granulomatosis and renal involvement, with special reference to relapse rate, renal and patient survival and morbidity from serious infections. METHODS A retrospective analysis was carried out of 108 patients presenting with Wegener's granulomatosis and active(More)
BACKGROUND The main purpose of this study was to examine histopathological changes seen in renal biopsies from patients with Wegener's granulomatosis (WG) with varying degrees of renal involvement and to study possible correlations between the morphological variables and the severity of the disease. METHODS Ninety-four patients with WG and active renal(More)
BACKGROUND The incidence of end-stage renal disease is especially high in men, and some studies indicated that smoking is a risk factor for men only. We investigated associations between obesity, smoking, and physical inactivity and chronic kidney disease (CKD) in the general population and whether risk for CKD was restricted to men. METHODS This was a(More)
BACKGROUND Antineutrophil cytoplasmic autoantibodies (ANCA) are directed against antigens located in the cytoplasm of neutrophil granulocytes and monocytes. Detection of ANCA has proved to be a useful diagnostic tool for a group of systemic vasculitis, especially Wegener's granulomatosis. Both indirect immunofluorescence (IIF) and ELISA have been used to(More)
BACKGROUND The cardiovascular risk implications of a combined assessment of reduced kidney function and microalbuminuria are unknown. In elderly persons, traditional cardiovascular risk factors are less predictive, and measures of end organ damage, such as kidney disease, may be needed for improved cardiovascular mortality risk stratification. METHODS The(More)
BACKGROUND Hypertensive renal damage has become one of the most important causes of end-stage renal failure (ESRF) in Western countries. Affected patients rarely have a kidney biopsy and their diagnoses therefore remain uncertain. The objective of the present study was to examine patients suspected of renal glomerular disease, which at biopsy proved to have(More)
BACKGROUND There is a well-known association between membranous nephropathy (MN) and cancer, and patients with MN usually are examined for cancer at the time of diagnosis. The long-term risk of cancer after MN is not well studied. STUDY DESIGN Cohort study with record linkage between the Norwegian Kidney Biopsy Registry and Norwegian Cancer Registry. (More)
BACKGROUND The aim of our study was to examine patients with mesangioproliferative glomerulonephritis (MPGN), with or without glomerular IgA deposits, and to analyse the effect of different clinical and histopathological variables at the time of biopsy on progression to end-stage renal failure (ESRF) and death. METHODS We retrospectively examined 273(More)
