to evaluate the possibility that a specific biosynthetic pathway deficiency exists in hyperreninemic hypoaldosteronism ( hh ) , basal and acth-stimulated levels of aldosterone and its immediate precursors 18-hydroxycorticosterone ( 18-ohb ) and corticosterone ( b ) were determined in eight hh patients , six critically ill subjects with normal aldosterone responsiveness , and nine healthy subjects .
