  • Title: Vasoactive hormones in children with chronic renal failure.
    Author: Rauh W, Hund E, Sohl G, Rascher W, Mehls O, Schärer K.
    Journal: Kidney Int Suppl; 1983 Nov; 15():S27-33. PubMed ID: 6368949.
    Abstract:
    Plasma renin activity (PRA), aldosterone, vasopressin and catecholamines were measured in 15 children (ages 7.3 to 16.2 years) with chronic renal failure (CRF) before and after one session of hemodialysis and in 15 control children. Basal levels of PRA and aldosterone in children with CRF did not differ significantly from control values, but showed a wider range. Uremic patients with nephronophthisis showed the highest basal PRA and aldosterone levels. In children with CRF, basal vasopressin levels were significantly higher (9.7 +/- [SEM] 2.0 ng/liter) than control values (3.2 +/- 0.8 ng/liter). Plasma noradrenalin and adrenalin concentrations were similar in children with CRF and controls. During hemodialysis, a fall in blood pressure and a rise in heart rate was observed in all children. PRA and catecholamines increased twofold to fivefold during dialysis while aldosterone and vasopressin showed a variable response. In contrast to reports in adults, there is no evidence for an insufficiency of vasoactive hormones or of the sympathetic nervous system in children on hemodialysis.
