Macroscopic hematuria in mesangial IgA nephropathy: Correlation with glomerular crescents and renal dysfunction

A Case of Arteriovenous Fistula after Renal Biopsy in an IgA Nephropathy Patient with Macroscopic Hematuria

Macroscopic hematuria is a common symptom in IgA nephropathy and is also one of the most frequent complications after a percutaneous renal biopsy. Here, we describe a patient with IgA nephropathy and recurrent macroscopic hematuria who developed an arteriovenous fistula after renal biopsy.

Absence of macroscopic hematuria in a case of IgA nephropathy and Graves' disease with acute renal failure.

Comparative study of IgA nephropathy with and without crescents.

Glomerular crescents were analyzed as a prognostic factor in retrospectively reviewed data from 144 patients with biopsy-proven IgA nephropathy. Crescents were found in 26 (18%) patients, and detected in 2 to 100% of glomeruli in each specimen. In 5% of the patients more than 50% of the glomeruli were affected. Thirty patients with IgA nephropathy without crescents were studied as a control gro...

IgA1 Protease Treatment Reverses Mesangial Deposits and Hematuria in a Model of IgA Nephropathy.

IgA nephropathy (IgAN), characterized by mesangial IgA1 deposits, is a leading cause of renal failure worldwide. IgAN pathogenesis involves circulating hypogalactosylated IgA1 complexed with soluble IgA Fc receptor I (sCD89) and/or anti-hypogalactosylated-IgA1 autoantibodies, but no specific treatment is available for IgAN. The absence of IgA1 and CD89 homologs in the mouse has precluded in viv...
