PLASMA RENIN ACTIVITY IN CHRONIC NEPHROPATHY

. Plasma renin activity (PRA) has been measured in 14 patients with chronic nephropathy maintained on hemodialysis. Most of the patients were hypertensive at the time of measurement, and mean PRA was significantly elevated. No correlation between PRA, mean blood pressure and dialytic controllability of hypertension could be established. As in normal subjects and in hypertensives of varying etiology there appeared, however, to be an inverse correlation between PRA and plasma sodium concentration.
