Abstract
Low posaconazole plasma concentrations (PPCs) have been associated with breakthrough invasive fungal infections. We assessed the correlation between pre-steady state PPCs (obtained between day 3-5) with those obtained during steady-state in 48 patients with underlying hematological malignancies receiving posaconazole oral solution prophylaxis. Pre-steady state PPCs correlated significantly with those obtained at steady-state (Spearman r=0.754, p<0.001). ROC curve analysis of pre-steady state PPCs revealed an AUC of 0.884 (95%CI 0.790-0.977) for predicting satisfactory PPCs at steady-state.
