Systematic evaluation of propofol population pharmacokinetic models and development of a literature-supported new meta-model for critically ill preterm and term neonates

The study developed and validated a rapid LC-MS/MS method for quantifying cefazolin in capillary whole blood collected via VAMS, plasma, and plasma ultrafiltrate, showing robust performance across matrices and successful application in a pediatric pilot cohort for therapeutic drug monitoring.

Dried saliva collected with the Mitra device correlated strongly with wet saliva but poorly with plasma unbound and total concentrations, indicating it is not a reliable substitute for plasma in routine therapeutic drug monitoring of mycophenolic acid and its glucuronide metabolite. Capillary blood collected via VAMS remains a promising alternative for long term monitoring in paediatric patients.

The study validated a VAMS-based LC-MS/MS method for measuring sirolimus levels, showing it was clinically equivalent to the standard whole blood method and suitable for therapeutic drug monitoring in paediatric transplant patients, supporting the use of decentralised microsampling for this purpose.

The study developed and validated LC-MS/MS methods for ganciclovir in serum, dried serum spots, and VAMS-Mitra devices. In 80 pediatric renal transplant recipients, VAMS showed interchangeability with serum samples while extending stability to at least 49 days at room temperature, making decentralised therapeutic drug monitoring more feasible for transplant patients.
