    Notes: Abstract In order to evaluate the possible role of vasoactive hormones in the mechanism of exaggerated sodium loss due to reduced renal mass we measured plasma concentration of atrial natriuretic peptide (ANP), aldosterone, plasma renin activity (PRA), plasma noradrenaline, and dopamine, in 12 children with advanced chronic renal failure (mean CIn17.8-2.6,x± SEM, CPAH93.5±17 ml/min per 1.73 m2, FENa7.0±0.95%). No patient had clinical signs of volume overload. Plasma concentrations of ANP were not significantly different from those of healthy agematched controls (29.2±7.2 vs 23.2±3.1 fmol/ml) and did not correlate with urinary sodium excretion. Plasma concentrations of aldosterone, PRA and noradrenaline, were also within the physiological range, while plasma dopamine levels were elevated (260±36 vs 98±11 pg/ml, 〈0.001). Our data do not support the notion that ANP or the renin-aldosterone axis play a major role in the adaptation of remaining nephrons to maintain long-term sodium balance in normotensive children with chronic renal failure.

    Atrial natriuretic peptide and cyclic 3′5′-guanosine monophosphate as indicators of fluid volume overload in children with chronic renal failure (1992)

    Notes: Abstract Plasma atrial natriuretic peptide (ANP) and cyclic 3′5′-guanosine monophosphate (cGMP) were investigated as indicators of fluid volume overload in children and adolescents with chronic renal failure. Plasma ANP and cGMP were measured in both paediatric patients with chronic renal failure (n=17, mean serum creatinine 371±242 μmol/l) and those with end-stage renal disease on haemodialysis (n=18). cGMP was higher in children with chronic renal failure than in 45 healthy controls (1.0±0.4 vs 2.1±0.8 nmol/l,P〈0.01), whereas plasma ANP was similar (26.9±9.7 vs 34.0±12.3 pmol/l). Both ANP and cGMP were markedly elevated in children with end-stage renal disease before haemodialysis and fell significantly during dialysis. During dialysis body weight decreased by 1.6±0.7 kg, corresponding to 4.5±2.1% of body weight. Plasma ANP correlated positively with plasma cGMP in haemodialysed patients (r=0.43,P〈0.05). Reduction in body weight and in mean arterial pressure correlated more closely with plasma ANP than with cGMP. Therefore, elevation of plasma ANP appears to indicate volume overload in children undergoing haemodialysis, but whether it can be used also in children with chronic renal failure requires further investigation
