Epidemiology of fungal infections in liver transplant recipients: a six-year study of a large Brazilian liver transplantation centre

ABSTRACT

Liver transplant seems to be an effective option to prolong survival in patients with end-stage liver disease, although it still can be followed by serious complications. Invasive fungal infections (ifi) are related to high rates of morbidity and mortality. The epidemiology of fungal infections in Brazilian liver transplant recipients is unknown. The aim of this observational and retrospective study was to determine the incidence and epidemiology of fungal infections in all patients who underwent liver transplantation at Albert Einstein Israeli Hospital between 2002-2007. A total of 596 liver transplants were performed in 540 patients. Overall, 77 fungal infections occurred in 68 (13 percent) patients. Among the 77 fungal infections, there were 40 IFI that occurred in 37 patients (7 percent). Candida and Aspergillus species were the most common etiologic agents. Candida species accounted for 82 percent of all fungal infections and for 67 percent of all IFI, while Aspergillus species accounted for 9 percent of all fungal infections and for 17 percent of all IFI. Non-albicans Candida species were the predominant Candida isolates. Invasive aspergillosis tended to occur earlier in the post-transplant period. These findings can contribute to improve antifungal prophylaxis and therapy practices in Brazilian centres.
