Nonsteroidal antiinflammatory drugs (NSAID), such as indomethacin, reduce production of renal prostaglandins and markedly impair renal function in patients with cirrhosis and ascites. To determine if simultaneous administration of oral prostaglandin analogs minimizes the renal impairment, 10 patients received indomethacin and either misoprostol or placebo in a double-blind, crossover study. Indomethacin reduced urinary sodium from 23 +/- 9 to 8 +/- 4 microEq/min in 4 hours. Misoprostol with indomethacin tended to prevent the fall in urinary sodium (from 35 +/- 15 to 46 +/- 21 microEq/min at 4 hours), but sodium excretion fell to the same level in both groups by 8 hours (6 +/- 3 microEq/min). Indomethacin reduced creatinine clearance in 4 hours by 49%; misoprostol plus indomethacin reduced creatinine clearance by only 34%. Misoprostol tended to minimize or delay the nephrotoxic effects of indomethacin, suggesting that more potent prostaglandin analogs may prevent the renal impairment induced by NSAID.

Misoprostol (200 micrograms) has been shown to acutely counteract the indomethacin-induced renal dysfunction in well compensated cirrhotic patients. The aim of this study was to determine if the prophylactic value of misoprostol was dose-dependent. Parameters of renal hemodynamics and tubular sodium and water handling were assessed by clearance techniques in 26 well compensated cirrhotic patients before and after an oral combination of 50 mg of indomethacin and various doses of misoprostol. The 200-micrograms dose was able to totally abolish the deleterious renal effects of indomethacin, whereas the 800-micrograms dose resulted in significant worsening of renal hemodynamics and sodium retention. These changes were maximal in the hour immediately after medications and slowly returned toward base-line levels thereafter. These results suggest that the renal protective effects of misoprostol is dose-dependent. However, until this apparent ability of 200 micrograms of misoprostol to prevent the adverse effects of indomethacin on renal function is confirmed with chronic frequent dosing, it would be prudent to avoid nonsteroidal anti-inflammatory therapy in patients with cirrhosis.

Twenty-five liver cirrhosis patients with endoscopically demonstrated gastro-duodenal mucosal damage (microhemorrhages, erosions, ulcers) were treated with misoprostol (prostaglandin E1) 400 mg/die. Eleven patients (44%) had abdominal pain and diarrhea and stopped treatment. Three months later, a new endoscopy was performed in the 11 patients that completed the study (3 patients were lost at follow up). Mucosal damage was stable in 5 patients (45%) and improved in 6 patients (55%), with complete absence of mucosal lesions in 2 patients (P = 0.027, Wilcoxon Ranks test). No case of worsening was observed and no patient had digestive bleeding during treatment. Digestive bleeding is a common complication of liver cirrhosis, originating in about 50% of cases from gastro-duodenal mucosal damage. Misoprostol suggests itself as a possible alternative therapy to the drugs usually utilized in these lesions (beta-blockers, H2-inhibitors), but individual intolerance is frequent and must be preliminary excluded.
