BACKGROUND AND OBJECTIVES Prednisone and calcineurin inhibitors are the mainstay therapy of idiopathic nephrotic syndrome (INS) in children. However, drug dependence and toxicity associated with protracted use are common. Case series suggest that the anti-CD20 monoclonal antibody rituximab (RTX) may maintain disease remission. DESIGN, SETTING,(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)
Apolipoprotein A-I is the main protein of high-density lipoprotein particles, and is encoded by the APOA1 gene. Several APOA1 mutations have been found, either affecting the lecithin:cholesterol acyltransferase activity, determining familial HDL deficiency, or resulting in amyloid formation with prevalent deposits in the kidney and liver. Evaluation of(More)
Primary focal segmental glomerular sclerosis (FSGS) commonly presents with nephrotic syndrome. Spontaneous remission is rare and persistent nephrotic syndrome is a marker of poor prognosis. For this reason, obtaining remission using drugs with minimal side effects is desirable. The treatment of FSGS, however, represents a challenge. Not only is there a lack(More)
IgA nephropathy is the most common form of primary glomerulonephritis, with a variable prevalence depending on the geographic area of examination. Marked differences in disease prevalence has suggested that genetics could play a role in the pathogenesis of the disease, indicating the existence of susceptibility genes detected with different frequencies in(More)
BACKGROUND AND OBJECTIVES Atheroembolic renal disease (AERD) can require dialytic support. Because anticoagulation may trigger atheroembolization, peritoneal dialysis may be preferred to hemodialysis. However, the effect of dialysis modality on renal and patient outcomes in AERD is unknown. DESIGN, SETTINGS, PARTICIPANTS, & MEASUREMENTS A subcohort of 111(More)
Already known to ancient Egyptians, gout is one of the first diseases which have been described as a clinical entity. To date, gout is the most common form of inflammatory arthritis. Gout is defined by the deposition of monosodium urate crystals within tissues, causing episodes of acute arthritis and the development of tophi, nephrolithiasis, and urate(More)
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most frequent genetic disease, characterized by progressive development of bilateral renal cysts. Two causative genes have been identified: PKD1 and PKD2. ADPKD phenotype is highly variable. Typically, ADPKD is an adult onset disease. However, occasionally, ADPKD manifests as very early onset(More)
Factors predicting rapid progression of kidney disease in ADPKD can be divided into genetic (non-modifiable) and clinical (modifiable) risk factors. Patients harbouring PKD1 mutations, in particular if truncating, have a more severe form of ADPKD. Clinical risk factors include decrease in glomerular filtration rate and renal blood flow at a young age; high(More)
