Abstract

Rates of multidrug-resistant organisms (MDRO) colonization among intestinal transplant (ITx) recipients have not been reported. Colonization rates with vancomycin-resistant Enterococcus (VRE), carbapenem-resistant Gram-negative bacteria (CR-GNB), and methicillin-resistant Staphylococcus aureus (MRSA) were obtained retrospectively in adults undergoing ITx (isolated or multivisceral) from 1/2009 to 12/2015. We assessed for VRE, CR-GNB, and MRSA bacteremia during the first year post-transplant for patients colonized with VRE, CR-GNB, and MRSA, respectively, and for those who were not colonized. We evaluated whether the number of hospitalization days and one year post-transplant survival were different in MDRO-colonized patients. Forty-five ITx recipients were identified. Twenty-eight (62%) were colonized with MDRO [VRE in 22 (50%) patients, MRSA in seven (16%), and CR-GNB in six (15%)]. VRE and CR-GNB-colonized patients were more likely to develop VRE and CR-GNB bacteremia, respectively, than noncolonized patients [8/22 (36%) vs. 1/23 (4%), and 4/6 (67%) vs. 2/39 (5%), P < 0.05 for both]. There was no difference in one-year survival between MDRO-colonized and noncolonized patients. However, survival was lower among MDRO-colonized patients who developed VRE, CR-GNB, or MRSA bacteremia (P < 0.001). MDRO colonization was common among our ITx recipients. VRE and CR-GNB bacteremia was more common among colonized patients, and survival was lower among MDRO-colonized patients who developed bacteremia.
