Abstract：
:A strong influence of urinary kallikrein excretion on the salt sensitivity of blood pressure has been recently suggested in normotensive patients. To evaluate the relationship between kallikrein and salt sensitivity in essential hypertension, active kallikrein excretion, plasma renin activity, atrial natriuretic peptide and aldosterone levels were evaluated in 37 male hypertensives (mean age 43.3 +/- 4.7 years) after two weeks on a normal NaCl diet (120 mmol NaCl per day). After kallikrein determination, salt sensitivity was assessed in a randomized cross-over double-blind fashion by evaluating the blood pressure response to a high (240 mmol NaCl per day for two weeks) and a low (40 mmol NaCl per day for 2 weeks) NaCl intake. Blood pressure changes were evaluated considering as baseline blood pressure the measurement taken at the end of the 2 weeks under normal NaCl intake. Patients were classified as salt sensitive when a diastolic blood pressure change of 10 mm Hg or more occurred after both periods of low and high NaCl intake. At the end of the assessment of salt sensitivity, 19 hypertensive patients (mean age 43.0 +/- 4.6 years) were resistant. The urinary excretion of active kallikrein was significantly lower (P < 0.0001) in salt sensitive (0.51 +/- 0.36 U/24 hr) than in salt resistant patients (1.28 +/- 0.48 U/24 hr). Also, plasma atrial natriuretic peptide levels were higher in salt sensitive than in salt resistant hypertensives (P < 0.02), and a significant correlation between urinary kallikrein and plasma atrial natriuretic peptide was demonstrated in salt sensitive hypertensives (r = -0.691, P < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
