title: Acute renal failure secondary to leukocyte-mediated acute glomerular injury.
abstract: Acute glomerulonephritis can cause acute renal failure. Activated neutrophils and monocytes are major effectors of glomerulonephritic renal failure. Adhesion molecules, granule enzymes, reactive oxygen radicals, lipid metabolites, and cytokines of activated neutrophils and monocytes mediate glomerular capillary constriction, occlusion, and destruction. Injurious products and biologically active mediators released by activated leukocytes have profound functional effects on mesangial cells and endothelial cells, which in turn participate in the disturbance of glomerular function, for example, by altering capillary diameter and surface area. The glomerular inflammatory events result in decreased glomerular capillary ultrafiltration coefficient and glomerular filtration rate, as well as other functional perturbations.
