Abstract Background and Aims Crescentic glomerulonephritis (C-GN) is characterized by severe glomerular inflammation injury that leads to crescent formation, rapid loss of kidney function prognosis in absence prompt immunosuppressive therapy. Depending on the histological findings, there are three main types C-GN: anti-glomerular basement membrane antibody GN (anti-GBM GN), immune complex GN, p...

RATIONALE IgG4-related disease (IgG4-RD) is a newly recognized systemic disease. The typical pathological finding in the kidney is abundant IgG4-positive plasma cell infiltration with characteristic storiform fibrosis in the interstitium. Antibodies of the IgG4 subclass have been linked to certain autoimmune diseases including antiproteinase 3 (PR3) anti-neutrophil cytoplasmic antibody (ANCA) o...

BACKGROUND AND OBJECTIVES Only rare cases of concurrent membranous glomerulonephritis (MGN) and antineutrophil cytoplasmic antibody (ANCA)-associated necrotizing and crescentic glomerulonephritis (NCGN) have been reported. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The authors report the clinical and pathologic findings in 14 patients with MGN and ANCA-associated NCGN. RESULTS The cohort...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis is traditionally viewed as a small vessel disease. We report a patient with cANCA antibodies directed against proteinase-3 with asymptomatic aortic involvement, in combination with diffuse alveolar haemorrhage and pauci-immune, necrotizing crescentic glomerulonephritis. A review of the literature is discussed.

UNLABELLED Osteopontin expression in human crescentic glomerulonephritis. BACKGROUND Osteopontin is a molecule with diverse biological functions, including cell adhesion, migration, and signaling. The expression of osteopontin has been demonstrated in a number of models of renal injury in association with accumulations of monocyte/macrophages, including recent reports of osteopontin expressio...

We report a case of a 42-year-old patient who presented with Wegener's granulomatosis complicated by pulmonary renal syndrome, i.e., diffuse alveolar haemorrhage and rapidly progressive crescentic glomerulonephritis. The patient was treated with plasmapheresis and immunosuppressive drugs--intravenous cyclophosphamide and methyl prednisolone. The clinical, haematological and biochemical paramete...

In order to determine the extent to which specific forms of glomerulonephritis (GN) contribute to the pool of crescentic GN, renal tissues from 17 crescentic GN patients were examined with special attention to glomerular and interstitial neutrophil infiltration. Renal tissues from five normal kidneys served as normal controls. Renal biopsy tissues from five patients with postinfectious GN in wh...

In the early 1990s, an international working group of experienced renal pathologists, the Renal Histology group, set up a scoring system for biopsies with anti-neutrophil cytoplasmic autoantibody (ANCA)-associated glomerulonephritis. This scoring system subdivided glomerular, interstitial and vascular lesions and served as a tool for the evaluation of all renal biopsies from studies of the Euro...
