Long-term Prognosis of Cirrhosis After Spontaneous Bacterial Peritonitis Treated With Ceftriaxone

Abstract

Spontaneous bacterial peritonitis (SBP) is a frequent infection in cirrhotic patients with ascites, with a poor prognosis. The aims of this study were to determine the long-term survival of cirrhotic patients with SBP treated with ceftriaxone and to identify predictive factors related to survival. We studied 47 first episodes of SBP treated with ceftriaxone with a mean follow-up of 272 days. Nineteen variables were recorded to evaluate their relation to survival. The most frequent organism that caused SBP was Escherichia coli (40%). Spontaneous bacterial peritonitis resolution was achieved in 67% of patients. After resolution, SBP recurrence was observed in 44% of patients. The cumulative probability of survival was 68.1% at 1 month and 30.8% at 6 months. After uni-and multivariate analyses of all cases, SBP resolution (p = 0.0001) and international normalized ratio (INR) (p = 0.0057) were found to be related to survival. Another analysis performed after SBP resolution and SBP recurrence showed that ascitic fluid–positive culture (p = 0.0344) and INR (p = 0.0218) had statistical significance as variables predictive of long-term survival. We conclude that the survival of cirrhotic patients is very short after the first episode of SBP, a fact probably related to advanced liver disease, as liver dysfunction (INR) is the most important factor related to long-term patient survival.
