Other primary glomerular diseases

This chapter covers the other primary glomerular diseases, including their pathologies, treatment options for their management, and risk factors. Some of these primary glomerular diseases are quite rare. This chapter covers fibrillary glomerulonephritis (FGN), collagenofibrotic glomerulopathy, thin basement membrane nephropathy (TBMN), lipoprotein glomerulopathy (LPG), ‘pure’ mesangial proliferative glomerulonephritis (MesPGN), IgM nephropathy, C1q nephropathy, idiopathic nodular glomerulosclerosis, and C4 glomerulopathy. It describes the use of light microscopy, immunofluorescence, electron microscopy, and immunochemistry where applicable. For each disease, the natural history, clinical presentation, pathogenesis, and pathology are described, and, where applicable, specific studies are discussed. Any specific treatments are outlined for each.
