摘要
Background Infective endocarditis (IE) is a rare complication following solid organ transplant (SOT); data on the clinical features and outcomes of IE in SOT recipients in the modern era are limited. Methods We conducted a single-center retrospective cohort study of IE diagnosed from 1/2008-12/2014 in SOT recipients, who were matched by age and microorganism to cases of IE in non-SOT, to describe the clinical features and outcomes. Results There were 14 cases of IE identified in SOT recipients matched to 56 non-SOT controls. Median time from transplant to IE was 1017 days (IQR 379-1830). Compared to non-SOT patients, SOT patients were more likely to be undergoing current hemodialysis (16% vs 36%) and to possess indwelling central venous catheters within the 30 days prior to diagnosis of IE (27% vs 50%). No SOT patients had documented drug use as a risk factor for IE whereas 6 (11%) non-SOT did.Enterococcuswas the most common etiologic agent and was isolated in 50% of cases; only one fungal infection was identified, a mixed infection withCandida. Thirty-day mortality was 14% in SOT patients, significantly higher versus no deaths in non-SOT (P = .037). Conclusions The present study illustrates a change in epidemiology of IE in SOT patients characterized by IE that generally occurs more than one-year post-transplant, is due to bacterial infection rather than fungus, and appears to be health care associated. Multicenter studies are merited to explore transplant-specific risk factors for IE in the special population of SOT patients.
