Concerns about increasing bacterial resistance to vancomycin, have caused the adult treatment guidelines to recommend higher trough concentrations based on the type and location of infectious disease. Although these recommendations are not specific to children, the values can be extrapolated. This prospective study was designed to evaluate efficacy of current vancomycin dosing recommendations t...

(Suggestions are based on Level III and IV evidence) • In both adults and children, C2 monitoring of CSA is superior to C0 as a predictor of AUC 0–4 and AUC 0–12. The C3 level is marginally superior to C2 for AUC 0–12. • Targeting AUC 0–4 levels for CSA of greater than 4400 ng/mL or C2 levels of greater than 1.5 by the end of the first week post transplant is associated with less acute rejectio...

We report on 28 patients who underwent voriconazole monitoring because of disease progression or toxicity. A relationship (P<0.025) between disease progression and drug concentration was detected. Favorable responses were observed in 10/10 patients with concentrations above 2.05 microg/ml, while disease progressed in 44% (n=18) of patients with concentrations below 2.05 microg/ml.
