Class of 2012 Abstract / Specific Aims: The primary aim of this study was to determine the incidence of posaconazole and voriconazole concentration monitoring that occurs in transplant patients receiving antifungal prophylaxis therapy. The secondary aim was to determine whether voriconazole and posaconazole serum concentrations were used for dose adjustments.
Methods: Patients status post either a liquid or solid organ transplant over the age of 1 year who received invasive fungal infection prophylaxis with either posaconazole or voriconazole between the dates of February 1, 2010 through January 31, 2011 while admitted to academic medical center were included in this descriptive retrospective study. This study has been approved by the Institutional Review Board. Data collected on each subject included demographic information, type of transplant, posaconazole or voriconazole concentrations, and duration and dosage adjustments.
Main Results: 54 subjects were identified who received either voriconazole or posaconazole for fungal prophylaxis after transplant. For subjects who were prescribed posaconazole (N = 8), concentration monitoring was performed in 50% of subjects and 0% of posaconazole dose adjustments were based on concentrations. For subjects who were prescribed voriconazole, concentration monitoring and dose adjustments based on voriconazole concentrations were performed in 20% and 78% of subjects respectively. Adverse outcomes associated with the use of antifungal therapy were reported in 0% of the posaconazole therapy group and 17% of the voriconazole therapy group.
Conclusions: Both posaconazole and voriconazole concentrations were obtained from patients who were receiving antifungal therapy for invasive fungal infection prophylaxis. Adjustments of prophylactic doses are not well characterized.
