ABSTRACT

Thirty-three children with post-streptococcal acute glomerulonephritis, age x:8.3 years (range 6-12) were studied prospectively. Mean initial hematocrit (Hct) was 31.6 percent with 90 percent 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 percentaje of transferrin saturation were normal for this age group although 75 percent of the children had increased serum ferritin levels. At the time of discharge, Hct increased to 35.1 percent but 44 percent still had anemia. Hct increased spontaneously for 105 days stabilizing at 38 percent. 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 II, suggest other pathogenic factors

ABSTRACT

Se controlan 29 pacientes, de edad promedio 15,6 años (rango 10 a 21 a 3m) que estuvieron hospitalizados por glomerulonefritis aguda post estreptocócica 8 años antes y fueron motivo entonces de un estudio clínico, histopatológico e inmunológico. Desde la nefritis hasta el control actual, nueve estuvieron absolutamente sanos; los restantes relatan algunos síntomas difíciles de relacionar con el episodio agudo. Trece presentan un peso adecuado a la talla y el resto está bajo el percentil 50 con respecto a los valores de las tablas OMS y de los valores promedios ICNND 1963. Todo están normotensos en este control y presentan creatinina plasmática y depuración de creatinina normales. Sólo tres casos tienen proteinuria; de 0,26 g en dos y de 1,04 g/l 100 en otro; pero en exámenes posteriores las proteinurias fueron negativas. Se pudo examinar a dos pacientes de los cuatro que en la biopsia alejada de la nefritis, aparecían como activos o crónico; en ellos el examen actual es normal. Se concluye que este seguimiento de GNA apoya la posición del buen pronóstico de esta enfermedad cuando se presenta en la infancia
