Racial Differences in Aldosterone Excretion and Plasma Aldosterone Concentrations in Children

New England Journal of Medicine, 1989
Blacks are more likely to have hypertension, have lower levels of plasma renin activity, and typically consume less potassium than whites. Whether blacks and whites secrete different amounts of aldosterone is less clear. We estimated aldosterone secretion indirectly in 715 children, 249 of whom were black, by measuring their nocturnal rates of urinary ...

Plasma aldosterone concentration of cats

The Veterinary Journal, 1998
Aldosterone concentrations in the plasma of specific-pathogen-free, domestic, short-hair cats given sodium replete diets were measured by a radio-immunoassay. Plasma samples assayed were taken from male and female cats of 8, 12, 17, 20, 26, 29, 40 and > 52 weeks of age, from adult non-pregnant queens, and from queens in the ninth weeks of pregnancy and

PLASMA ALDOSTERONE CONCENTRATION IN ANEPHRIC CHILDREN

Acta Endocrinologica, 1974
ABSTRACT The effect of extractive haemodialysis and of postural changes on the plasma aldosterone concentration has been studied in 5 anephric children. The plasma aldosterone concentration tended to be lower after haemodialysis in spite of the extracellular volume depletion induced. No regular response occurred after orthostatism. There was no

THE RELATIONSHIP BETWEEN SALIVARY ALDOSTERONE AND PLASMA FREE ALDOSTERONE CONCENTRATIONS

Clinical Endocrinology, 1986
The proportion of aldosterone in plasma not bound to proteins (% plasma free aldosterone, %PFA) was measured using an equilibrium dialysis technique and was found to lie predominantly in the range 25–40% although extremes of 20% and 60% were encountered.

Plasma aldosterone concentrations in neonatal spontaneously hypertensive rats

Life Sciences, 1982
Abstract Plasma aldosterone concentrations were found to be higher in the newborn, presumably prehypertensive, spontaneously hypertensive rat at 5, 10 and 20 days of age compared to age-matched normotensive Wistar-Kyoto (WKY). In addition, plasma aldosterone concentrations were seen to rise in newborn WKY in contrast to findings in Wistar rats and ...

Plasma aldosterone concentration is associated with white matter lesions in patients with primary aldosteronism

Endocrine, 2021
Primary aldosteronism (PA) is the most frequent form of secondary hypertension. Hypertension is a risk factor for cognitive decline and dementia. White matter lesions (WMLs) are linked to vascular risk factors, which increase the risk of dementia. We aimed to analyze the association of PA-related parameters and WMLs in patients with PA.We conducted a ...

Diagnostic evaluation of plasma aldosterone concentration to plasma renin activity ratio in primary aldosteronism

Frontiers of Medicine in China, 2008
Using the plasma aldosterone concentration to plasma renin activity ratio (PAC/PRA ratio) as the screening test of choice for primary aldosteronism in hypertensive patients, we studied the clinical characteristics and the diagnostic value of PAC/PRA ratio in primary aldosteronism.

Effects of routine heparin therapy on plasma aldosterone concentration

Acta Endocrinologica, 1991
Abstract. Changes in plasma aldosterone, plasma renin activity, plasma cortisol, serum sodium and potassium concentrations were studied in 9 patients with thromboembolic diseases treated with heparin. Heparin was administered at doses of 700-1000 units/h for 7-10 days. Plasma aldosterone decreased from 239±33 to 114±25 pmol/l during heparin therapy and

Aldosterone plasma concentration in horses with heart valve insufficiencies

Research in Veterinary Science, 2008
In humans and small animals, heart disease can lead to an increase in aldosterone, and the aldosterone level correlates with the severity of the heart disease. In horses similar interactions may be possible and may lead to an increase in aldosterone in horses with heart valve insufficiencies.
