Abstract
Cirrhotic patients are at increased risk of developing infection, sepsis and death. Enterobacteriaceae and nonenterococcal streptococci are the main bacteria responsible for spontaneous and urinary infections in this population. Prompt and appropriate treatment is basic in the management of cirrhotic patients with infection. Third-generation cephalosporins continue to be the gold-standard antibiotic treatment of the majority of infections acquired in the community because responsible strains are usually susceptible to β-lactams. By contrary, nosocomial infections are nowadays frequently caused by multiresistant bacteria (extended-spectrum β-lactamase-producing Enterobacteriaceae, Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and vancomycin-resistant enterococci among others) that are nonsusceptible to the main antibiotics. Treatment of these infections requires the use of broader spectrum antibiotics (carbapenems) or of antibiotics that are active against specific resistant bacteria (glycopeptides, linezolid, daptomycin, amikacin and colistin). Empirical antibiotic schedules must be adapted to the local epidemiological pattern of antibiotic resistance. Careful restriction of antibiotic prophylaxis to the high-risk population is also mandatory to reduce the spread of multiresistant bacteria in cirrhosis.
