Everolimus quantification in peripheral blood mononuclear cells using ultra high performance liquid chromatography tandem mass spectrometry.

A reliable ultra high performance liquid chromatography tandem mass spectrometry method has been developed for the determination of everolimus in human peripheral blood mononuclear cells (PBMCs). Protein precipitation was used for sample preparation. Analysis was performed on an UPLC Waters Acquity system.

Impact of extracorporeal membrane oxygenation and continuous venovenous hemodiafiltration on the pharmacokinetics of oseltamivir carboxylate in critically ill patients with pandemic (H1N1) influenza.

Purpose: The neuraminidase inhibitor oseltamivir is a recommended treatment for influenza A (H1N1) infection. In rare cases, some patients develop influenza-associated multiple organ failures, requiring rescue therapies such as extracorporeal membrane oxygenation (ECMO) or continuous venovenous hemodiafiltration (CVVHDF). This study was designed to evaluate the impact of ECMO and CVVHDF on the pharmacokinetics of oseltamivir carboxylate (OC) in critically ill patients with pandemic (H1N1) influenza treated with oseltamivir.
