title: Peritoneal hemosiderosis in pediatric patients with nephrogenic ascites.
abstract: Nephrogenic ascites associated with maintenance hemodialysis is a complex problem with poorly understood pathophysiology. We report 4 pediatric patients investigated between 1986 and 1990. All the patients treated with maintenance hemodialysis required multiple blood transfusions. Each patient was carefully evaluated for factors potentially relevant to ascites, and serum ferritin levels were found to be extremely high. Peritoneoscopy which was utilized in all patients led to a specific diagnosis of hemosiderosis in the peritoneum and liver biopsies. In 1 patient, lymph node biopsy also showed iron deposition. We believe that iron deposition played a role in changing the permeability of the peritoneum and is presumed to be a pathogenetic factor in nephrogenic ascites.
