  • Title: Renal hemodynamics and the renin-angiotensin system in cirrhosis.

    Abstract:
    The interrelationship between renal hemodynamics and the renin-angiotensin-aldosterone system in 28 nonazotemic cirrhotic patients has been studied. Patients were divided into three groups: A) Patients without ascites nor edema; B) Patients with ascites and a relatively high sodium excretion (41.9 +/- 12.9 mmol/day); and C) Patients with ascites and very low sodium excretion (4.8 +/- 0.6 mmol/day). Renin and aldosterone levels significantly increased in group C. A significant correlation was observed between plasma aldosterone concentration and urinary sodium excretion, and between plasma renin activity and aldosterone levels. There were no significant differences in urine flow, glomerular filtration rate, effective renal plasma flow, or renal blood flow between the three groups of patients, in spite of marked differences in renin and aldosterone levels. Renal perfusion was not related to plasma renin activity either in the overall sample of patients or in the individual groups. These results show that factors other than total renal perfusion are involved in renin secretion in cirrhosis.
