Liquid-chromatography coupled to high resolution mass spectrometry (LC-HRMS) is currently the method of choice for untargeted metabolomic analysis. The availability of established protocols to achieve a high confidence identification of metabolites is crucial. The aim of this work is to describe the workflow that we have applied to build an...

Background Therapeutic drug monitoring (TDM) of antibiotics in children is of fundamental importance for effective patient management. The use of dried blood spot (DBS) offers a number of advantages over conventional blood collection. The aim of this study is to develop and validate a method to measure piperacillin/tazobactam in DBS. Results...

The aim of this work is to evaluate volumetric absorptive microsampling (VAMS) from capillary blood as an alternative strategy for therapeutic drug monitoring (TDM) in patients treated with the newly availableGW-purified form of cannabidiol (Epidiolex®). Afast ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)...

Background:Therapeutic drug monitoring (TDM) of antiepileptic drugs (AEDs) is commonly performed on plasma or serum. The use of dried plasma spots (DPSs) could represent a useful tool to facilitate sample shipment to reference laboratories. In this article, the authors describe the application of a commercially available UHPLC-MS/MS method for...

Aim: DBS might be an appropriate microsampling technique for therapeutic drug monitoring of caffeine in infants. Nevertheless, its application presents several issues that still limit its use. This paper describes a validated DBS-LC-MS/MS method for caffeine. Results: The results of the method validation showed an hematocrit dependence. In the...

The paper reports on the use of therapeutic drug monitoring for linezolid in the decision-making process to continue or not its administration in an infant. Linezolid is effective against methicillin-resistant Staphylococcus aureus but is off-label in pediatrics. The use of therapeutic drug monitoring, as in our case, allows an informed...

Adenosine Deaminase 2 Deficiency (DADA2) (OMIM: 607575) is a monogenic, autoin-flammatory disease caused by the loss of functional homozygous or heterozygous mutations in the ADA 2 gene (previously CECR1, Cat Eye Syndrome Chromosome Region 1). A timely diagnosis is crucial to start Anti-TNF therapies that are efficacious in controlling the...

Purpose: Interest in cannabis-based therapies has recently increased, due to the availability of cannabidiol (CBD) for the treatment of epilepsy without psychoactive effects. Therapeutic drug monitoring can prevent drug interactions and minimize drug toxicity. We evaluated a volumetric absorptive microsampling (VAMS) method combined with...
