Background/aims: Patients with cirrhosis of the liver are prone to bacterial infections. Therapeutic interventions such as endoscopic sclerotherapy increase the risk of bacterial infections in these patients. Following insertion of a transjugular intrahepatic portosystemic shunt (TIPS), the incidence of severe bacterial infections was recently shown to be 20% after elective procedures. This finding suggests antibiotic prophylaxis with the TIPS procedure. Antibiotic prophylaxis using cefotiam or cefotaxime/ampicillin did not significantly reduce infectious complications. The aim of the present study was therefore to investigate the efficacy of two different doses of a long-acting cephalosporin in prevention of bacterial infection after TIPS.
Methodology: Eighty-two patients with cirrhosis (age: 52 +/- 2 years) who underwent elective TIPS were randomized to receive a single i.v. dose of either 1 g or 2 g Ceftriaxone 1 hour before the intervention. Patients with evidence of or suspected infections and patients on antibiotic therapy within 7 days prior to TIPS were excluded. Body temperature was monitored t.i.d. for 1 week and white blood count (WBC) and C-reactive protein (CRP) were determined before TIPS and 1 day and 1 week after TIPS.
Results: Only 2 of 82 patients (2.6%) showed signs of infection following TIPS insertion: One of 40 patients receiving 1 g Ceftriaxone and 1 of 42 patients receiving 2 g Ceftriaxone prior to TIPS developed temperature > 38.5 degrees C. In the latter patient this was due to pneumonia. This patient received antibiotic treatment with imipenem for 10 days. Temperature in the other patient normalized within 12 hours and he did not require antibiotic treatment. No significant differences in temperature, WBC and CRP between the different doses of Ceftriaxone were observed.
Conclusions: Prophylactic treatment with Ceftriaxone reduces the reported incidence of bacterial infections after TIPS in patients with cirrhosis of the liver. Prophylaxis with 1 g Ceftriaxone seems as efficacious as 2 g.
