Abstract
Invasive aspergillosis (IA) is a rare but fatal disease among liver transplant recipients (LiTRs). We performed a multicenter 1:2 case-control study comparing LiTRs diagnosed with proven/probable IA and controls with no invasive fungal infection. We included 62 IA cases and 124 matched controls. Disseminated infection occurred only in 8 cases (13%). Twelve-week all-cause mortality of IA was 37%. In multivariate analyses, systemic antibiotic usage (adjusted odds ratio [aOR], 4.74; P = .03) and history of pneumonia (aOR, 48.7; P = .01) were identified as independent risk factors associated with the occurrence of IA. Moreover, reoperation (aOR, 5.99; P = .01), systemic antibiotic usage (aOR, 5.03; P = .04), and antimold prophylaxis (aOR, 11.9; P = .02) were identified as independent risk factors associated with the occurrence of early IA. Among IA cases, Aspergillus colonization (adjusted hazard ratio [aHR], 86.9; P <.001), intensive care unit stay (aHR, 3.67; P = .02), disseminated IA (aHR, 8.98; P <.001), and dialysis (aHR, 2.93; P = .001) were identified as independent risk factors associated with 12-week all-cause mortality, while recent receipt of tacrolimus (aHR, 0.11; P = .001) was protective. Mortality among LiTRs with IA remains high in the current era. The identified risk factors and protective factors may be useful for establishing robust targeted antimold prophylactic and appropriate treatment strategies against IA.
