| Abstract: | Two children with prototypic hemolytic-uremic syndrome had prolonged acute dialysis-dependent renal failure (74 and 84 days) associated with a state of hyperproteinemia induced by extensive infusion of fresh frozen plasma (283 and 307 units). We believe that the hyperproteinemia prolonged the duration of renal failure. Following cessation of plasma therapy, the hyperproteinemic state reversed, the degree of proteinuria decreased and renal function quickly recovered. Although the pathophysiological mechanism requires further evaluation, we speculate that an alteration in the colloid oncotic pressure and/or aggravation of tubulointerstitial injury due to overload-proteinuria may have increased the duration of renal failure. |
