Pediatric Glomerular Disease Tissue Markers (H-37628)

The goal of this study is to identify pathogenic mechanisms for disease, novel treatment targets, and better diagnostic and prognostic tools for children with idiopathic immune complex kidney diseases. These children make up to 5% of immune complex kidney disease, but do not qualify for diagnosis with the more common causes: lupus nephritis, membranous nephropathy, membranoproliferative nephritis (MPGN), IgA nephropathy, or post-infectious glomerulonphritis.
