To establish the role of electron microscopy in the diagnosis of glomerular diseases we reviewed retrospectively 113 renal biopsies. The biopsies were included in this study if tissue was received for light microscopy, immunofluorescence and electron microscopy. The biopsy was assigned to one of the three following categories on the contribution of the ultrastructural findings to the primary di...

We report a case of a 71-year-old man with rapidly progressive nephritic syndrome and dual positivity for anti-glomerular basement membrane antibody and myeloperoxidase-specific anti-neutrophil cytoplasmic antibody. Renal biopsy revealed crescentic, mainly cellular, glomerulonephritis with granulomatous lesions, and advanced membranous changes. Membranous nephropathy had apparently existed for ...

Exciting progress recently has been made in our understanding of idiopathic membranous nephropathy, as well as treatment of this disease. Here, we review important advances regarding the pathogenesis of membranous nephropathy. We will also review the current approach to treatment and its limitations and will highlight new therapies that are currently being explored for this disease including Ri...

Relapsing polychondritis (RP) is a rare, chronic, and potentially fatal multisystemic inflammatory disorder targeting cartilaginous structures. This disorder is frequently associated with rheumatoid arthritis, systemic vasculitis, connective tissue diseases, and hematologic disorders, but renal involvement is unusual. In the literature, associated renal pathology includes mesangial expansion, I...

Corticosteroids were successfully used to treat a 66-year-old man with retroperitoneal fibrosis (RPF) and previously diagnosed membranous nephropathy. Proteinuria was noted at the age of 51 years, and membranous nephropathy was diagnosed by renal biopsy. Ten years later, he presented with right hydronephrosis and renal dysfunction, and was diagnosed as having RPF based on the typical diagnostic...

Membranous nephropathy (MN) is a unique glomerular lesion that is the most common cause of idiopathic nephrotic syndrome in nondiabetic white adults. About 80% of cases are renal limited (primary MN, PMN) and 20% are associated with other systemic diseases or exposures (secondary MN). This review focuses only on PMN. Most cases of PMN have circulating IgG4 autoantibody to the podocyte membrane ...

The management of membranous nephropathy first requires the recognition of whether the disorder is primary (idiopathic) or secondary. Next, a familiarity with its natural history and knowledge of our current capacity to predict those patients with the worst outcome is reviewed. Treatment options of those at risk of progression with immunosuppressive drugs is then discussed along with the requir...

BACKGROUND Arterial thromboses, including cerebral infarction, are a rare complication of the nephrotic syndrome. SUMMARY OF REPORT A 37-year-old woman presented with right upper extremity ischemia, left middle cerebral artery thrombosis, and right cerebellar infarction. She quickly herniated, and postmortem evaluation revealed membranous nephropathy. Increased fibrinogen and decreased free p...
