Abstract
Clostridium difficile is a bacterial enteric pathogen, which causes clinical disease among solid organ transplant (SOT) recipients. This large, single-center, retrospective study describes incidence, demographics, and impact of C. difficile infection (CDI) among adult SOT recipients, cardiac (n = 5), lung (n = 14), liver (n = 9), renal (n = 26), and multiorgan (n = 9) patients transplanted and diagnosed with CDI (geneB PCR) between 9/2009 and 12/2012. The overall incidence of CDI in our population during the 40-month period of study was 4%. CDI incidence among cardiac, lung, liver, and renal transplant recipients was 1.9%, 7%, 2.7%, and 3.2%, respectively (P = 0.03 between organ-types). Median time from transplant to CDI for all was 51 (14-249) days, with liver recipients having the shortest time to infection, median 36 (15-101) days, and lung recipients having a longer time to infection, median 136 (29-611) days. Antibiotic exposure within 3 months of CDI was evident in 45 of the 63 (71%) patients in this study, 80%, 79%, 100%, 58%, and 67% of cardiac, lung, liver, renal, and multiorgan transplant recipients, respectively. Most patients (83%) were hospitalized within the 3 months preceding CDI. Recipients were followed for a median time of 23 (16-31) months; at the time of last follow-up, 83% of allografts were functioning, and 86% of patients were alive. One death and 1 graft failure were causally related to CDI. CDI had an overall incidence of 4%; clinicians should have heightened awareness for CDI, especially among patients receiving antibiotics, with increased monitoring and aggressive management of CDI.
