RESUMO

The prevalence of chronic renal failure (CRF) increases every day, and among adult patients, the principal causes are metabolic diseases, responsible to almost 70% of patients who are under dialysis. However, there are few studies regarding epidemiologic data of CRF in children. The objective of this study was to describe clinical and epidemiological profiles of children and adolescents with CRF who have been followed up by the Pediatric Nephrology Team of the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP), along 22 years of experience. Data of 121 medical records have been reviewed, and 21 variables have been collected from each of them. From the total of the patients, 58.7% were male and 41.3% were female. The average of age of registration was 59.1 months. Patients who were younger than 5 years summed 62.5% of all. From the total of patients, 63% lived in Ribeirão Preto or in cities until 300km far. The primary renal diseases described were: uropathies (48.8%), glomerulopathies (20.7%), congenital or polycystic renal dysplasia (7.4%), vasculopathies (6.6%), tubular diseases (2.5%), miscellaneous (7.4%) and unknown causes (6.6%). Among the glomerulopathies group, the histological patterns described were: Focal Segmental Glomerulosclerosis (25.0%), Diffuse Mesangial Proliferation (20.8%), Advanced Glomerulonephritis (12.5%), Crescentic Glomerulonephritis (8.3%) and the Alport Syndrome (8.3%). From total of biopsies, 4.2% were not able to define a diagnosis, and 20.8% of the glomerulopathiespatients were not undergone renal biopsy. From the total, 59.8% of the patients were under the 5o percentile of the NCHS curve in their registration, related to their height. The follow up showed a variation of 2 to 263 months, which average was 67.5 months. The blood creatinine level showed a variation of 0.5 to 12.1 mg/dL, which average was 3.0 mg/dL. The average Glomerular Filtration Rate, estimated by the Schwartzs formula, was 27.4 mL/min/1,73m2. At the onset, 62.3% of the patients were classified at the stages 4, 5 or under dialysis. Hypertension was described in 56.2% of the patients at any time of the follow up. Metabolic acidosis was described in 53.7% of the patients at the onset. Patients who underwent dialysis summed 38.0%, and the peritoneal modalities performed 80.4% of all cases. Renal transplantation was performed in 24.8% of the patients, with similar proportions of live-related and cadaveric donors. The proportion of deaths during the 22 years of study was 22.3% of all. The rest of them were delivered to the Clinical Team of the HCFMRP-USP (17.4%) or still had been followed up by the Pediatric Nephrology Team by December 2005 (38.8%). We concluded that the population described had similar clinical and epidemiological characteristics to the other Brazilian and international data available.
