Azathioprine Therapy in a Pediatric TPMT-Deficient Patient-Still an Option.

abstract：:Monitoring of serum voriconazole concentrations has been proposed to optimize therapeutic effect and minimize toxicity. However, little is known about the clinical use of voriconazole therapeutic drug monitoring (TDM) by treating physicians. Four hundred seventy-eight episodes corresponding with 161 adult patients (me...
