Renin-angiotensin system in an infant with malignant renovascular hypertension. 1976

F Fyhrquist, and P Kuitunen, and N Kojo

A one-year-old girl with malignant renovascular hypertension had increased levels of plasma renin activity and angiotensin II concentration in peripheral blood and in blood from the affected kidneys as compared with that from the contralateral kidney. Unilateral nephrectomy was followed by resolution of the hypertension and normalization of the activity of the renin-angiotensin system.

D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.
