Arterial Changes in Children Undergoing Renal Transplantation

Research output: Contribution to journalArticle

Abstract

Introduction: Pathological changes of large arterial walls and the heart have been described in patients with chronic renal failure. The aim of the study was to verify the incidence of arterial changes among our series of pediatric patients with end-stage renal disease undergoing transplantation. Patients and methods: From January 2004 to December 2006, 26 patients (15 boys and 11 girls) of overall mean age of 13.12 years (range = 3-27 years) underwent renal transplantation in our department. The pretransplant dialysis treatment was peritoneal in eight and hemodialysis in 18 cases. All patients were divided in two groups according to primary renal disease: group A were 18 patients with congenital urinary malformations; and group B, eight patients with acquired glomerular diseases. In each case, a sample of artery from both donor (aortic patch of kidney) and recipient (iliac patch of graft allocation) was obtained during renal transplantation. The donors were considered to be the control group. Results: Light microscopy showed pathological changes in 12/26 recipient arteries: nine showed light fragmentation of the internal elastic lamina; two, more severe fragmentations; and one, fragmentation of the internal elastic lamina associated with mucopolysaccharide deposits. Pathological changes were more evident in group A than B, but the difference was not significant (P > .05). Among the donor group, 11 patients showed light fragmentation of the internal elastic lamina, but there was no significant difference with the recipients (P > .05). Conclusions: Among our group of patients, we observed only slight modifications of the arterial wall. These changes were nonspecific, similar to those in a control group of donors matched for age. A possible explanation of these findings may depend on the short time of dialysis before transplantation.
