BACKGROUND Primary Sjögren's syndrome is a connective tissue disorder affecting primarily the lacrimal and salivary glands, resulting in xerophtalmia and xerostomia. Extraglandular manifestations are frequent and may include renal involvement. METHODS We studied the prevalence and nature of kidney involvement in 60 Italian patients with primary Sjögren's(More)
BACKGROUND Atheroembolic renal disease (AERD) is caused by showers of cholesterol crystals released by eroded atherosclerotic plaques. Embolization may occur spontaneously or after angiographic/surgical procedures. We sought to determine clinical features and prognostic factors of AERD. METHODS AND RESULTS Incident cases of AERD were enrolled at multiple(More)
BACKGROUND A supplemented very-low-protein diet (sVLPD) seems to be safe when postponing dialysis therapy. STUDY DESIGN Prospective multicenter randomized controlled study designed to assess the noninferiority of diet versus dialysis in 1-year mortality assessed by using intention-to-treat and per-protocol analysis. SETTING & PARTICIPANTS Italian uremic(More)
BACKGROUND Dialysis increases patient life expectancy but is associated with clinically severe and costly complications. Health and economic benefits could derive from postponing dialysis with a supplemented very low-protein diet (sVLPD). METHODS An economic evaluation was conducted to compare benefits and costs of sVLPD versus dialysis in elderly CKD5(More)
There are no solid data on the real advantage of an early start of dialysis, as suggested by the DOQI guidelines. Uremic patients frequently have a poor nutritional status. However, we cannot distinguish between the detrimental effect on nutrition of too low a residual renal function or too long a period of low protein-diet, per se. However, it appears that(More)
Cholesterol crystal embolism, sometimes separately designated atheroembolism, is an increasing and still underdiagnosed cause of renal dysfunction antemortem in elderly patients. Renal cholesterol crystal embolization, also known as atheroembolic renal disease, is caused by showers of cholesterol crystals from an atherosclerotic aorta that occlude small(More)
We performed a genome-wide association study (GWAS) of IgA nephropathy (IgAN), the most common form of glomerulonephritis, with discovery and follow-up in 20,612 individuals of European and East Asian ancestry. We identified six new genome-wide significant associations, four in ITGAM-ITGAX, VAV3 and CARD9 and two new independent signals at HLA-DQB1 and(More)
We carried out a genome-wide association study of IgA nephropathy, a major cause of kidney failure worldwide. We studied 1,194 cases and 902 controls of Chinese Han ancestry, with targeted follow up in Chinese and European cohorts comprising 1,950 cases and 1,920 controls. We identified three independent loci in the major histocompatibility complex, as well(More)
BACKGROUND Very low-protein intake during chronic kidney disease (CKD) improves metabolic disorders and may delay dialysis start without compromising nutritional status, but concerns have been raised on a possible negative effect on survival during dialysis. This study aimed at evaluating whether a very low-protein diet during CKD is associated with a(More)
BACKGROUND Strict control of serum calcium and phosphate concentrations is paramount to prevent secondary hyperparathyroidism in haemodialysis (HD) patients. Standard intermittent low-flux HD (Lf-HD) is not sufficient to reach this goal. The aim of this study was to evaluate the effect of on-line haemodiafiltration (Ol-HDF) on serum calcium (sCa), phosphate(More)
