Orthostatic changes in norepinephrine (NE; A), epinephrine (Epi; B), arginine vasopressin (AVP; C), renin (D), aldosterone (Aldo; E), ANG II (F), and ANG-(1–7) (G) in children. There were no differences between groups in the supine position or with HUT. However, both HUT(−) (n = 18) and HUT(+) (n = 30) groups exhibited significant increases in NE, Epi, AVP, renin, and ANG II from the supine position to HUT. HUT(+) subjects had significantly higher AVP than HUT(−) subjects during HUT. There were no changes in Aldo or ANG-(1–7) levels observed from the supine position to HUT. Supine position vs. HUT: *P < 0.05, **P < 0.01, and ***P < 0.001; HUT(−) vs. HUT(+) subjects: #P < 0.05.
