Background and Aim: There have been no trials comparing the prophylactic effect of oral quinolone and intravenous cephalosporin antibiotics and elucidating the predictive factors for the occurrence of bacterial infections in cirrhotic patients with gastrointestinal bleeding in Asian-Pacific region.
Methods: One hundred and thirteen patients with advanced liver cirrhosis and active gastrointestinal hemorrhage were enrolled in our study. The patients were randomly allocated into either the oral ciprofloxacin group (n = 50, 500 mg every 12 h) or the intravenous ceftriaxone group (n = 63, 2.0 g per day for 7 days).
Results: Proven or possible infections were significantly more frequent in the patients in the oral ciprofloxacin group (34.0%) than the intravenous ceftriaxone group (14.3%, P = 0.002). The intestinal permeability index (IPI, mean [SD]) measured the day after admission was significantly higher in the patients with proven or possible infections (1.45 [0.96]) compared with the no infection group (0.46 [0.48], P < 0.01). By multivariate analysis, oral ciprofloxacin prophylaxis and higher IPI at the time of inclusion were independent and significant predictors for proven or possible infections. By receiver operating characteristic curve analysis, the best cutoff value of IPI for the prediction of the occurrence of bacterial infection was 0.62%.
Conclusions: The frequency of proven or possible infections was significantly lower in the intravenous ceftriaxone group compared with the oral ciprofloxacin group. The IPI measured the day after admission is a good clinical parameter predicting the occurrence of infection in these patients.
