Primary prophylaxis with ciprofloxacin in cirrhotic patients with ascites: a randomized, double blind study
Annals of Hepatology
probability curves were constructed with the Kaplan-Meier method and compared by the log-rank test. RESULTS. 95 patients were randomized to ciprofloxacin group (n = 49; 51.6%) and placebo group (n = 46; 48.4%). Six-teen (32.6%) patients in the ciprofloxacin group developed bacterial infections and thirteen (28.2%) patients developed bacterial infections in the placebo group (p = NS). The probability to remain free of bacterial infections did not reach statistical significance (p = 0.38).
... (p = 0.38). Probability of survival at 24 weeks was 91% in placebo group and 98% in the ciprofloxacin group (p = 0.28). The absolute risk reduction was 5%, the relative risk reduction was 6% and the NNT was 20 patients. CONCLUSION. Primary prophylaxis with ciprofloxacin for one month in cirrhotic patients with ascites who do not have a currently accepted indication, did not show a preventive effect on the development of bacterial infections at one month follow-up. Moreover in women could increases the odds for UTI. The administration of ciprofloxacin seemed to decrease the risk of mortality.
