Bacterial infections in cirrhosis

Abstract

Spontaneous bacterial peritonitis, urinary tract infections, respiratory infections and bacteremia are the most frequent infective complications in cirrhosis. These infections are due to the concomitant presence of different facilitating mechanisms including changes in the intestinal flora and in the intestinal barrier, depression of activity of the reticuloendothelial system, decreased opsonic activity of the ascitic fluid, neutrophil leukocyte dysfunction and iatrogenic factors among others. The fact, that the probability of having a microorganism responsible for the infection quinolone resistant is higher than 30% should be taken into account when treating any infection in a cirrhotic patient receiving selective intestinal decontamination with quinolones, and therefore, quinolones as empiric treatment are not indicated.
