Nontyphoid Salmonella Bacteremia in Patients with Liver Cirrhosis

Background: Bacteremia is reported to occur in 4% to 9% of hospitalized patients with liver cirrhosis. Escherichia coli and Klebsiella pneumoniae are the most commonly isolated organisms. Only sporadic cases of nontyphoid Salmonella bacteremia are reported in the literature. In this study, we sought to determine the clinical features and prognosis of patients with liver cirrhosis and bacteremia due to nontyphoid Salmonella. Method: Data were collected by retrospective chart review. Results: From December 1996 to May 2003, we identified 23 patients (18 males, 5 females) with a median age of 58 years. The Child classification for liver cirrhosis was A in 4, B in 9, and C in 10 patients. Solid organ cancers were present in 14 patients: hepatocellular carcinoma in 13 patients and gastric carcinoma in 1 patient. Hospital death occurred in 11 patients (48 %): 7 died of sepsis and 4 of hepatic failure. Using a logistic regression model, the independent risk factors for death in patients with nontyphoid Salmonella bacteremia were young age and an advanced stage of liver cirrhosis. Conclusion: Most nontyphoid Salmonella bacteremia in patients with liver cirrhosis was community-acquired. An advanced stage of liver cirrhosis and hepatocellular carcinoma were common. The prognosis for young patients was unfavorable; this was seemingly due to hepatocellular carcinoma producing more unfavorable results in younger cirrhotic patients
