Rezafungin profylakse ved levertransplantation

24. september 2026 opdateret af: Fernanda P Silveira, MD, MS

Rezafungin-profylakse ved levertransplantation med høj risiko for invasiv svampeinfektion

This is an interventional study to evaluate the efficacy of rezafungin, a new echinocandin, for the prevention of invasive fungal infections (IFIs) after liver transplantation. Patients who receive rezafungin will be compared to a similar group of patients who underwent liver transplantation in the preceding two years for the incidence of IFIs.

Detaljeret beskrivelse

This is a single arm interventional study of consecutive liver transplant recipients who have consented to this rezafungin prophylaxis study. The outcome will be compared with that of similar group of patients not enrolled in the study and those who underwent liver transplant in the preceding two years (historical controls). Propensity score matching will be used to select retrospective cohort.

There will be 3 groups:

  1. Study group (prospective intervention cohort): Rezafungin (180 patients)
  2. Prospective control group (prospective control cohort): Patients who receive fluconazole/voriconazole or no antifungal prophylaxis as part of UPMC's tiered antifungal prophylaxis standard of care (20 patients: 10 who receive fluconazole/voriconazole and 10 who do not receive fluconazole/voriconazole)
  3. Historical control group (retrospective control cohort): Patients at risk for IFI who received fluconazole/voriconazole (tier approach) in the two years preceding this study (180 patients)

Beskrivelse

Inclusion Criteria:

  • Liver transplant recipient
  • 18 years of age or older
  • ≥1 risk factor(s) for IFI: living donor transplant, retransplantation, complicated operations (based on duration of transplant and number of blood products required in the peri-transplant period), choledochojejunostomy anastomosis, or peri-operative Candida colonization, recent Candida infection, renal replacement therapy post-transplant, and reoperation within the first 90 days of transplant.

Exclusion Criteria:

  • Participants who are perceived not to survive past 7 days after transplant
  • Participants who elect not to participate in the prospective trial
  • Participants who had active candidiasis at the time of transplant

Aktiv komparator: Prospective Control Cohort

Patients who receive fluconazole/voriconazole or no antifungal prophylaxis as part of UPMC's risk-based antifungal prophylaxis standard of care after liver transplant

UPMC uses a tiered approach to antifungal prophylaxis, based on risk factors for IFI. Fluconazole is used for recipients with risk factors for yeast infections: choledochojejunostomy, prolonged transplant time, receipt of >40 units of blood products within 24 hours of transplant, and Candida colonization or infection within 3 months prior to transplant. Voriconazole is used for recipients with risk factors for mould infections: re-transplantation, renal failure requiring renal replacement therapy, fulminant hepatic failure as indication for transplant, intra-abdominal/thoracic re-exploration within the first month after transplant. No prophylaxis is given if there are no risk factors for yeast or mould infections.
