Abstrakt: Background and Aim: Primary prevention of spontaneous bacterial peritonitis (SBP) is an important strategy to reduce morbidity and mortality in cirrhotic patients with ascites. Efficacy and safety of alternating rifaximin and norfloxacin as primary prophylaxis is questionable.
Methods: Three hundred thirty-four cirrhotic patients with high SAAG (≥1.1) ascites, protein level in ascitic fluid less than 1.5 g/dL with advanced liver disease (Child-Pugh score >9 points with serum bilirubin level >3 mg/dL) or renal impairment (serum creatinine level >1.2 mg/dL, blood urea nitrogen level >25 mg/dL, or serum sodium level <130 mEq/L) were included in an open-label, randomized study aimed at comparing alternating use of norfloxacin and rifaximin vs. norfloxacin or rifaximin alone as primary prophylaxis for SBP. Both intention-to-treat and per-protocol efficacy analyses were done after 6 months of treatment by assessment of ascitic fluid neutrophil count. Safety analysis was done for all intention-to-treat populations.
Results: Alternating norfloxacin and rifaximin showed superior prophylaxis by intention-to-treat (74.7 vs. 56.4% vs. 68.3%, p < 0.048). Pairwise analysis showed that alternating regimen had lower probability to develop SBP when compared to a norfloxacin-based regimen in intention-to-treat (p = 0.016) and per protocol analysis (p = 0.039). There was no difference among the studied groups regarding the incidence and severity of adverse events reported.
Conclusions: Alternating norfloxacin- and rifaximin-based primary prophylaxis for SBP showed higher efficacy with the same safety profile when compared with monotherapy of norfloxacin.
