Abstract

The pre-analytical stability of different metabolites in serum and plasma samples of healthy humans was determined. Metabolite concentrations were quantified using targeted metabolomics based on liquid chromatography-tandem mass spectrometry. Both reliable and stable metabolites were identified as are suitable for targeted metabolomics analysis in multicenter studies. In a multicenter clinical trial, specific metabolic changes that were induced by single metformin intake or short-term therapy in newly diagnosed type 2 diabetes patients were discovered.<br />Die präanalytische Stabilität von Metaboliten in Serum- und Plasmaproben gesunder Probanden wurde bestimmt. Metabolitkonzentrationen wurden basierend auf Flüssigchromatographie-Massenspektrometrie mittels ‘targeted metabolomics‘ quantifiziert. Dabei konnten verlässliche und stabile Metaboliten identifiziert werden, welche für ‘targeted metabolomics‘ Analysen geeignet sind. In einer multizentrischen Studie wurden spezifische Metabolitveränderungen aufgedeckt, welche durch das Medikament Metformin in Patienten mit Typ 2 Diabetes hervorgerufen wurden.
