ABSTRACT
The aim of this research is to evaluate the recent changes in microorganisms causing spontaneous bacterial peritonitis in cirrhotic patients, antibiotic resistance, and response to empirical cephalosporin therapy. A total of 218 patients with ascites secondary to cirrhosis were enrolled. Parenteral cefotaxime or cefepime was given to patients who had a neutrophil count of 250/mm(3) or more or a positive bacterial culture of ascitic fluid. Antibiotic failure was defined by an absence of clinical improvement and an insufficient decrease in neutrophil count of ascites (<25% of initial value) by the third day of therapy. Of all the patients, 44.6% had culture-negative neutrocytic ascites, 24.8% had spontaneous bacterial peritonitis, and 10.1% had monomicrobial nonneutrocytic bacterascites. Growth in culture was observed in 76 patients (34.9%). The two most common isolated bacteria were Escherichia coli (33.8%) and coagulase-negative Staphylococcus (CoNS; 19.7%). The two cephalosporins were effective against E. coli (82%) and but not against CoNS (44%), while levofloxacin showed reasonable activity against both E. coli (71%) and CoNS (90%) in vitro. We confirmed a recent increased incidence of spontaneous bacterial peritonitis caused by Gram-positive bacteria. Levofloxacin seems to be a good alternative treatment for patients with uncomplicated spontaneous ascites infections.
