Hypokalemic alkalosis, hyperreninemia, aldosteronism, normal blood pressure and normal juxtaglomerular apparatus--a new syndrome of renal alkalosis.

An infant with hypokalemic alkalosis, hyperreninemia, aldosteronism, normal blood pressure and normal juxtaglomerular apparatus (JGA) is described. This infant, along with other similar patients reported in the literature, represents a new syndrome of renal alkalosis, clinically and chemically similar to Bartter's syndrome, but without hyperplasia of the JGA.
