  • Title: [Biological factors influencing response to diuretics in patients with cirrhosis and ascites].
    Author: Lenaerts A, Codden T, Henry JP, Van Cauter J, Meunier JC, Ligny G.
    Journal: Gastroenterol Clin Biol; 2001 Mar; 25(3):268-72. PubMed ID: 11395674.
    Abstract:
    PURPOSES: To examine the biological factors influencing response to diuretics in patients with cirrhosis and ascites. METHODS: Sixty-nine patients were evaluated. Patients were classified into 3 groups: group 1: "good responders" (responding to spironolactone 200 mg/day), group 2: "bad responders" (responding to spironolactone doses above 200 mg/day or requiring addition of furosemide), and group 3: "non-responders" (not responding to spironolactone 400 mg/day and furosemide 160 mg/day). RESULTS: There were 30 patients in group 1, 24 in group 2 and 15 in group 3. The degree of activation of the renin-aldosterone and sympathetic system in group 2 was significantly higher than in group 1 and lower than in group 3. Natriuresis in group 2 (11 +/- 0.7 mEq/24h) was significantly below group 1 (20 +/- 2 mEq/24h) and above group 3 (5 +/- 0.6 mEq/24h). CONCLUSIONS: In patients with cirrhosis and ascites, the degree of activation of the renin-aldosterone and sympathetic nervous system influences diuretic response of ascites and is estimated by measured baseline natriuresis.
