Abstract

Prostaglandins play an important role in the maintenance of renal hemodynamics and water excretion in cirrhosis. To investigate whether the administration of prostaglandins improves renal function in cirrhotic patients with ascites, 16 patients with functional renal failure and/or dilutional hyponatremia were given oral misoprostol, a prostaglandin E1 analogue (200 micrograms/6 h for 4 days; n = 9) or intravenous prostaglandin E2 (0.5 microgram/min for 1 h followed by 1 microgram/min for another hour; n = 7). The administration of misoprostol did not induce significant changes in the glomerular filtration rate (59 +/- 11 vs. 54 +/- 11 ml/min), sodium excretion (4.0 +/- 1.3 vs. 4.1 +/- 2.1 microEq/min), and free water clearance (2.4 +/- 0.8 vs. 2.1 +/- 0.9 ml/min), nor did it improve the natriuretic response to an intravenous bolus of 40 mg of furosemide (486 +/- 124 vs. 406 +/- 88 microEq/min). Similarly, an infusion of prostaglandin E2 did not induce significant changes in the glomerular filtration rate (baseline: 33 +/- 6; 0.5 microgram/min: 31 +/- 5; 1 microgram/min: 31 +/- 6 ml/min) and sodium excretion (5.7 +/- 2.7; 3.2 +/- 1.4; and 1.5 +/- 0.7 microEq/min, respectively), whereas free water clearance decreased significantly (1.1 +/- 0.7; 0.5 +/- 0.5; and -0.1 +/- 0.2 ml/min, respectively, p < 0.05). These results indicate that oral misoprostol or the intravenous infusion of prostaglandin E2 do not improve renal function in cirrhosis with ascites.
