Transient Elevation

Fifteen patients (ages 4 to 21 years) with coarctation of the aorta were studied. Ten patients were catheterized prior to surgery and both peripheral and renal vein plasma renin activity (PRA) were measured. Twelve patients were operated upon and peripheral PRA was measured pre-operatively and during the acute (postoperative day 0 to 10) and long-term postoperative (M = 112 days) period. Three children, not as yet operated upon, have been catheterized. Prior to catheterization, each received a sodium restricted diet (less than 500 mg NaCl) for 48 hours. The peripheral plasma renin activity was within the range of normal both preoperatively (18 ± 10 ng/ml) and long-term postoperatively (12 ± 5 ng/ml) p > 0.1 . The three patients who received sodium restriction prior to catheterization showed borderline to moderately elevated peripheral and renal vein PRA, suggesting that the renin apparatus responded to appropriate stimulation. During the acute postoperative period, each patient had a transient elevation of peripheral PRA. This elevation might be a partial stimulus to aldosterone production in the acute postoperative period. There was no correlation between peripheral PRA and blood pressure levels in the postoperative period. It was concluded that the renin-angio-tensin system does not play a significant role in maintaining the chronic hypertension which is associated with coarctation of the aorta.

Before And After

ABSTRACT Plasma renin activity (PRA) was measured by means of a radioimmunoassay for angiotensin I in 8 children with Wilms' tumour and in 12 normal children. Blood pressure in the patients was in the upper range of normal or just above. Before nephrectomy PRA levels were significantly higher than in normal children and adults. Five patients were studied before and after operation. A significant fall in PRA was observed. In one case blood was taken from the renal vein of the affected kidney; a high PRA level was detected. The results are in accordance with recent findings that Wilms' tumour may secrete increased amounts of renin.

Aldosterone Production

ABSTRACT Variations in plasma renin activity and urinary aldosterone excretion were studied in normal subjects submitted to salt restriction and simultaneous inhibition of ACTH production with a new synthetic steroid, 6-dehydro-16-methylene hydrocortisone (STC 407). At a dose of 10 mg t. i. d. this preparation exerts an inhibitory effect on the pituitary comparable to that of 2 mg of dexamethasone. In subjects maintained on a restricted salt intake, STC 407 does not delay the establishment of an equilibrium in sodium balance. The increases in endogenous aldosterone production and in plasma renin activity are also similar to those seen in the control subjects. A possible mineralocorticoid effect of STC 407 can be excluded. Under identical experimental conditions, the administration of dexamethasone yielded results comparable to those obtained with STC 407.
