Antifungal prophylaxis with voriconazole or itraconazole in lung transplant recipients: hepatotoxicity and effectiveness.

Invasive fungal infections (IFI) are common after lung transplantation and there are limited data for the use of antifungal prophylaxis in these patients. Our aim was to compare the safety and describe the effectiveness of universal prophylaxis with two azole regimens in lung transplant recipients. This is a retrospective study in lung transplant recipients from July 2003 to July 2006 who received antifungal prophylaxis with itraconazole or voriconazole plus inhaled amphotericin B to compare the incidence of hepatotoxicity. Secondary outcomes include describing the incidence of IFI, clinical outcomes after IFI and mortality. Sixty-seven consecutive lung transplants received antifungal prophylaxis, 32 itraconazole and 35 voriconazole and inhaled amphotericin B. There were no significant differences between groups in the acute physiology and chronic health evaluation (APACHE) score at the time of transplantation, demographic characteristics, comorbidities and concomitant use of hepatotoxic medications. Hepatotoxicity occurred in 12 patients receiving voriconazole and inhaled amphotericin B and in no patients receiving itraconazole (p < 0.001). There was no significant difference between groups with regard to the percentage of transplants with IFI, but one case of zygomycosis occurred in a transplant treated with voriconazole. Voriconazole prophylaxis after lung transplantation was associated with a higher incidence of hepatotoxicity and similar clinical effectiveness when compared to itraconazole.

Posttransplant lymphoproliferative disorders in lung transplant recipients: clinical experience at a single center.

OBJECTIVES: Posttransplant lymphoproliferative disorders (PTLD) can be a significant cause of morbidity in lung transplant (LT) recipients. Risk factors include Epstein-Barr virus (EBV) infection, particularly primary infection, and immunosuppression. This article updates the incidence and presentation of PTLD at our lung transplant program. METHODS: We retrospectively reviewed the immunosuppression, EBV serology, and cases of PTLD among 129 lung transplant recipients at risk who survived > 1 month. RESULTS: There were two cases of PTLD among 129 LT patients, 2/129 (1.6%). One of these patients was among the 6 EBV seroconverters, 1/6 (16.7%), and had a typical presentation of PTLD in the allograft resulting in dissemination and death. The second case of PTLD developed in an EBV seropositive recipient who presented 33 months following LT with isolated colonic involvement. He subsequently died from chronic rejection. CONCLUSIONS: The incidence of PTLD in a LT program with a large EBV seropositive population is low, 1.6%. The presentation of PTLD in LT recipients is variable and may present typically with allograft involvement in the first year following transplantation, or late with isolated, extrapulmonic involvement.
