title: [Diabetic nephropathy in children: study using the amount of urinary albumin].
abstract: It is well known that 30 to 50% of patients with Type I Diabetes develop nephropathy and that chronic renal failure, it's final pathway, is the main cause of death. Assessment of urinary albumin becomes an essential tool for identifying the population at risk of developing nephropathy, to study its physiopathologic mechanisms and to evaluate the response to therapeutic trials. The present article is a preliminary report on the study of urinary albumin excretion rate (AER) in a pediatric population with Type I Diabetes and its relation to teh duration of the disease. A RIA technique with double antibody was developed for albumin assessment, with a displacement range of 1 to 300 ng/tube. Urine samples were collected during short periods with water load as suggested by Mogensen. Thirty nine children (30 patients and 9 controls) free of renal disease and with normal blood pressure were studied. Patients were divided according to duration of the disease in: Group I: less than 5 years, Group II: 5 to 10 years and Group III: more than 10 years. Results (mean +/- SD) in micrograms/min/1.73 m2 were: Control Group (n = 9) 4.30 +/- 2.53, GI: (n = 12) 10.44 +/- 9.47, GII (n = 10) 8.03 +/- 7.27 and GIII (n = 8) 8.56 +/- 4.26. The mean value of the Control Group (+3 SD) 12 micrograms/min/1.73 m2, was considered as the upper normal limit. Thus, 16.6%, 40%, and 12.5% of children in Groups I, II and III had microalbuminuria.(ABSTRACT TRUNCATED AT 250 WORDS)
