title: [Rapidly progressive crescentic glomerulonephritis in the elderly].
abstract: Rapidly progressive glomerulonephritis (RPGN) is a syndrome characterized by glomerular lesions giving rise to acute renal injury that develops within a brief period of time, usually days or a few months. It is classified according to the underlying mechanism of injury and the immunofluorescence findings into four main disorders. In the last decade, nephrologists have witnessed a steady rise in the mean age of the patients diagnosed with RPGN. This observation may reflect an increase in the incidence of this entity and also a more timely diagnosis. We present 3 cases of RPGN in elderly patients, diagnosed within a 3 month period at our institution which illustrates the spectrum of these conditions.
