title: Potassium-renin-aldosterone relationships during the first year of life.
abstract: In order to gain insight into factors controlling aldosterone secretion during the first year of life, we studied the relationships between PRA, serum potassium, sodium, and serum aldosterone levels. While we found a dissociation during the early neonatal period, there was a high degree of correlation between serum aldosteron, PRA, and serum potassium by 3 to 12 months of age. This suggests that aldosterone secretion in the 3- to 12-month-old child, as in adults, is regulated by the circulating levels of potassium and angiotensin II.
