title: Peritonitis as a risk factor of acute renal failure in nephrotic children.
abstract: Idiopathic acute renal failure (IARF) is an uncommon but severe complication in children with relapsing nephrotic syndrome and may require long-term dialytic support until recovery of renal function takes place. Due to limited understanding of the pathophysiology of IARF, specific guidelines for its prevention and therapy have not been developed. Among triggering factors, peritonitis was present in half of all pediatric patients with this complication described in the English literature over the past 15 years. We report an additional nephrotic child who developed IARF following spontaneous bacterial peritonitis. The renal biopsy showed tubular epithelial changes consistent with acute tubular necrosis. A discussion of related literature and possible pathogenesis of this association is presented.
