Carbapenem-resistant Enterobacteriaceae (CRE) infection is associated with poor outcomes after solid organ transplantation (SOT). The significance of CRE colonization or infection prior to SOT is not known.
Patients who underwent SOT between 1/1/2007 and 7/31/2013 and had pre-SOT cultures positive for CRE were identified for chart review. The primary outcome was one-year mortality.
57 SOT recipients from 10 sites were identified. The median age was 54 and 68% were male. 59 pre-SOT CRE isolates were identified: Klebsiella pneumoniae (n=45), Escherichia coli (5), Enterobacter (4), Klebsiella oxytoca (2), Serratia marcescens (2) and Citrobacter freundii (1). The culture sources of pre-SOT CRE were as follows: urine (22), rectal swab (21), blood (16), respiratory (9), others (10). The date of the most recent CRE culture was a median of 54 days (range: 1-2064) prior to SOT. The transplanted organs were as follows: liver (27), heart (17), kidney (7), liver-kidney (3), lung (2), and intestine (1). 22 (39%) patients developed CRE infection a median of 7.5 days (range: 2-151) after SOT. There was a surgical complication prior to CRE infection in 11/22 (50%) patients. The CRE causing infections were K. pneumoniae (19), Enterobacter (2), and Serratia (1) and matched the pre-SOT CRE in all patients except one. The sites of infection were as follows: bloodstream (11), surgical site or intra-abdominal (11), urinary tract (6), and pneumonia (5). One-year mortality was 21% (12/57) in the entire cohort; 27% (6/22) in patients with post-SOT CRE infection; and 17% (6/35) in patients without post-SOT CRE infection.
CRE colonization/infection should not be considered an absolute contraindication for SOT since one-year survival is nearly 80%. Strategies to prevent post-CRE infection may further improve survival. Analyses to identify risk factors associated with post-CRE infection and mortality are in progress.
