Donor-derived vancomycin-resistant enterococci transmission and bloodstream infection after intestinal transplantation.

ABSTRACT: BACKGROUND:Transplant recipients are at high risk for infections. However, donor-recipient transmission of multidrug-resistant organisms (MDROs) remains mostly unaddressed in the protocols of pre-transplant infection and colonization screening. Vancomycin-resistant enterococci (VRE) are MDROs that colonize the gastrointestinal tract and are associated with a significant burden of disease. Besides the high mortality of invasive VRE infections, chronic colonization leads to costly isolation measures in the hospital setting. Whereas most post-transplantation VRE infections are endogenous and thus preceded by colonization of the recipient, conclusive evidence of VRE transmission via allograft in the context of intestinal transplantation is lacking. CASE PRESENTATION:We describe a donor-derived VRE infection after intestinal transplantation including small bowel and right hemicolon. The recipient, a 54-year old male with history of mesenteric ischemia and small bowel perforation due to generalized atherosclerosis and chronic stenosis of the celiac trunk and the superior mesenteric artery, developed an intra-abdominal infection and bloodstream infection after transplantation. VRE isolates recovered from the patient as well as from the allograft prior to transplantation were analyzed via whole genome sequencing. Isolates showed to be genetically identical, thus confirming the transmission from donor to recipient. CONCLUSIONS:This case underlines the relevance of donor-recipient VRE transmission and invasive infection in the context of intestinal transplantation, highlighting the need for preoperative MDRO screening that facilitates the prompt and effective treatment of possible infections as well as the timely establishment of contact precautions to prevent further spread.

Project description:Abstract Background Fecal Microbiota Transplantation (FMT) has proved to be an efficient therapy for recurrent C. difficile infection. Its indication is currently discussed for the decolonization of Multidrug-resistant organisms (MDRO) on the basis of mice experiments. Two recent publications suggest that it could be an efficient strategy for patients colonized with digestive MDRO colonization but few data are available for Carbapenem-Resistant Enterobacteria (CRE) and Vancomycin-Resistant Enterococcus (VRE) colonization. Methods We performed a FMT among patients colonized by CRE or VRE documented by at least 3 nonconsecutive positive swabs (including one in the week prior to the FMT). Procedure: 2 days prior to the FMT, patients received a proton pump inhibitor and a naso-duodenal tube was inserted to perform a bowel lavage with X-prep. FMT was performed with frozen feces from 4 donors previously screened for potential diseases using 5 syringes of 50 cc of feces diluted with saline. Patients were discharged after 24h and benefited of outpatient control swabs (PCR + culture) on day 7, 14, 21, 28 and each month during 3 months in order to assess the decolonization. The study is registered at ClinicalTrials.gov (NCT03029078). Results Seventeen individuals were included. Mean age was 69 ± 12.7 (SD) years. Eight patients were positive for CRE (KPC, OXA48 or NDM-1) and 9 for VRE. All suffered from severe underlying condition (hemodialysis, dementia, cirrhosis) or chronic wounds. Median functional autonomy scale was evaluated using the French Iso-Resources Groups (GIR)=4/6 IQR[3–6] supporting they were dependent persons. At 1-month follow-up, 3/8 patients were free from CRE and 5/9 from VRE. At 3-month follow-up, 3/8 patients were still free from CRE whereas 7/8 were free from VRE, considering one death from cirrhosis. Moreover, one of them received antibiotics during a week for a hospital-acquired infection a long time after FMT. No adverse events were reported. Conclusion FMT seems to be an attractive option to eradicate colonization of MDRO, especially for VRE. Limited data are available in the literature to determine response factors. Meanwhile its efficacy is moderate; it provides an alternative solution to quarantine for fragile and frequently hospitalized patients. More data and a controlled trial are required.
