title: [Chronic hemodialysis in children].
abstract: The clinical features of eight patients, four females, aged 4 to 15 years under chronic hemodialysis for terminal renal failure (creatinine clearance 10 ml.min.1,73 m2 or less) are reported. Initial diseases were Alport syndrome, systemic lupus erythematosus, chronic glomerulonephritis (n = 2), bilateral polycystic kidney, prune belly syndrome and reflux nephropathy (n = 2). Distal vascular approach by means of arteriovenous fistulas was preferred for these patients and the kinetic urea model was used to evaluate the performance of the procedure. Patients required nine to twelve hours of hemodialysis per week for optimal results. Mean weight decreases of 1 to 3 kg and reductions in blood urea nitrogen and serum potassium of 40 mg.dl and 2,5 mEq.1, respectively, were observed. The main complications of hemodialysis were the disequilibrium syndrome, infections at the site of insertion of the arteriovenous fistulae and congestive heart failure. Three patients were submitted to renal transplantation with live donors homografts: one died and the other two remain alive but under chronic hemodialysis. Five children are attending school regularly, and two of them are waiting a kidney donor for transplantation. Despite encouraging results chronic hemodialysis in children constitutes only primary supportive therapy prior to renal transplantation.
