Chronic renal failure in pediatrics 1996. Chilean survey.

The Nephrology Branch of the Chilean Pediatric Society has greatly influenced the development of government health plans regarding the management and care of patients under 18 years with chronic renal failure (CRF). In order to assess the status of children with CRF in Chile up to 1996, a questionnaire was sent to all pediatric nephrologists in charge of those children. The total sample was of 227 patients under 18 years, giving a national prevalence of 42.5 and an incidence of 5.7 per million inhabitants; of these patients, 50.7% were male, 58.6% over 10 years and 15% younger than 5 years. The most frequent etiologies of CRF were: obstructive uropathy, 18.1%; hypo/dysplasia, 16.7%; reflux nephropathy, 16.7%; and glomerulopathies, 16.3%. Although 48% of patients were on conservative medical treatment, 42.2% of these were in end-stage renal disease, 22.9% were on dialysis, and 29.1% had undergone renal transplantation. Of the dialysis group, 75% were on peritoneal dialysis. Of the transplanted children, 78.8% had normal renal function, but 16.7% returned to dialysis. Three-year graft survival and patient survival were 68% and 94%, respectively.

[Anemia associated with acute post streptococcal glomerulonephritis].

Thirty-three children with post-streptococcal acute glomerulonephritis, age mean: 8.3 years (range: 6 - 12) were studied prospectively. Mean initial hematocrit (Hct) was 31.6% with 90% showing Hct under the normal lower limit for this age group. Reticulocyte index (RI) was < 0.5 in half of the cases. Serum iron concentration, total iron binding capacity (TIBC) and percentage of transferrin saturation were normal for this age group although 75% of the children had increased serum ferritin levels. At the time of discharge, Hct increased to 35.1% but 44% still had anemia. Hct increased spontaneously for 105 days stabilizing at 38%. Based on Hct changes, 3 groups were defined: Group I (3 individuals): normal upon discharge; Group II (19): partial recovery at discharge, slow recovery stabilizing after 105 days; Group III (11): lower Hct, slower recovery but with RI significantly higher than group II (0.96 vs 0.45 p < 0.01). Our data suggest that although hemodilution is present in all, it may be considered the solely factor only in 3 cases (Group I). In group II, evidence of bone marrow depression was indicated by the low RI. On the other hand, the intense anemia that could not be justified only by hemodilution and marrow depression in group III, suggests other pathogenic factors.

[Blood pressure measurement with Doppler in normal newborn infants and infants].

Systolic blood pressure (SBP) was measured by Doppler method in an aleatory sample of 251 healthy children from south-east Santiago Chile (131 females and 120 males) which were divided by age in five groups: 0 to 28 days (n = 5) 1 to 5 months (n = 48), 6 to 11 months (n = 48), 12 to 17 months (n = 46) and 18 to 24 months (n = 45). Great dispersion of SBP values occurred among newborn infants (range 85 to 125) in comparison with groups 1 to 5 months (105 to 130), 6 to 11 months (118 to 130). Fifty and 95 percentiles were, respectively, 107 to 125; 116 to 130; 121 to 130; 118 to 130 and 120 to 130. These values were greater than those obtained by sphygmomanometry in a similar matched group of children.
