Changing options for prevention and treatment of infections in cirrhosis.

opinion statementBacterial infections are more frequent and severe in cirrhosis. Most prevalent infections are spontaneous bacterial peritonitis (SBP) and urinary infections followed by pneumonia, cellulitis and bacteremia. Cirrhosis increases the risk of sepsis, severe sepsis and death. Early diagnosis and adequate treatment of infections is essential in the management of cirrhotic patients. Recent data show that currently recommended empirical antibiotic therapy, mainly based on the use of β-lactams, is effective in community-acquired infections, but frequently fails in nosocomial and healthcare-associated infections. A marked increase in the prevalence of multidrug resistant (MDR) bacteria in the healthcare environment explains this finding. Patients developing nosocomial infections or with extended lengths of hospitalization are at higher risk for second infections that are associated with poor prognosis. Antibiotic strategies should therefore be selected according to the type, severity and site of acquisition of infection, and be adapted to the local epidemiological pattern of antibiotic resistance. Treatment of MDR bacteria requires the use of broader spectrum antibiotics (carbapenems) or those active against specific resistant bacteria (glycopeptides, linezolid, daptomycin, amikacin, colistin). Restriction of antibiotic prophylaxis to the high-risk populations, prevention of antibiotic overuse, and early de-escalation policies are also mandatory to prevent the spread of MDR bacteria in cirrhosis.
