- Abstract
MDR bacterial infections are frequent and difficult to treat in patients with cirrhosis. In addition to standard risk factors (epidemiology, antibiotic/healthcare exposure), colonization by MDR may increase the risk of MDR. The screening for rectal colonization by MDR pathogens could be a valuable tool to identify patients with cirrhosis at risk for MDR infection. Assess the prevalence and clinical impact of rectal colonization by MDR organisms in hospitalized patients with acute decompensation (AD) of cirrhosis. Consecutive patients admitted for AD and available rectal swab screening for MDR colonization at admission were enrolled. The following clinical endpoints were assessed: development of bacterial/MDR bacterial infection during hospitalization; transfer to intensive care unit (ICU); development of acute-on-chronic liver failure (ACLF); in-hospital mortality; 28- day mortality; 90-day mortality. 204 patients underwent rectal swab, and 37 (18.1%) tested positive for colonization by MDRO (carbapenem-resistant enterobacteriaceae accounted for 60% of cases). Patients colonized by MDRO had higher incidence of MDR infections (29,2 vs 6,2%; p=0,006), ACLF (43,2 vs 21%; p=0,009), transfer to ICU (16,2 vs 8,4%; p=0,018) and 90 days mortality (51,3 vs 14,3%; p<0,001). Almost two third of MDR infections were sustained by the same pathogen identified in rectal swab. In multivariable analysis, patients with MDR colonization had higher risk of developing MDR infections [HR=5.22; p=0.003], an increased risk of developing ACLF [OR=3.50, p=0.005], of being transferred to the ICU [OR=3.03; p=0.016], and of experiencing mortality during hospitalization [OR=9.38; p<0.001], as well as at 28 days [sHR=5.11; p<0.001] and 90 days [sHR=4.89; p<0.001]. Colonization by MDR organisms is associated with increased risk of developing MDR infections, organ failures and mortality in patients with AD of cirrhosis. Rectal swab could be a valuable screening tool for the clinical management of these patients. [ABSTRACT FROM AUTHOR]
