“…Liu and colleagues investigated different surrogate matrixes including PBS, twice charcoal-stripped serum, NaCl, and water to investigate the quantification of five steroid hormones. They demonstrated no significant differences in their data depending on the matrix used [52]. CTS- stripped serum or plasma may be a better representation of the matrix, however, to our knowledge there is no certified CTS-stripped serum available.…”

Background and AimsDigoxin, a cardiotonic steroid (CTS), is commonly prescribed for patients with atrial fibrillation and heart failure. Endogenous CTS have been implicated in cardiovascular disease pathogenesis and can interact with digoxin. We developed an ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) assay for the quantification of eleven CTS.Materials and MethodsIsotopically labelled internal standards were added to samples, followed by protein precipitation and solid-phase extraction. Steroids were separated using an Acquity uPLC chromatography system with a Waters CORTECS T3 column (1.6 μm 2.1x50 mm) and quantification performed on a Waters TQ-XS mass spectrometer using electrospray ionisation in positive ion mode. Separation used a methanol/ water elution system containing 0.1% formic acid and post-column infusion of lithium chloride.ResultsRun time was 13.5 minutes. Lower limits of quantification ranged from 0.025 to 0.1 ng/ml. Serum recovery ranged from 40.0-98.6% with matrix effects from -22.9% to 7.6%. Plasma recovery ranged from 27.4-83.9% and matrix effects were -27.6-39.1%. Accuracy and precision at three concentrations were within ideal range (<15%) for seven CTS and <20% for the others.ConclusionThis validated UHPLC-MS/MS method provides a comprehensive assessment profiling 11 cardiotonic steroids, offering a sensitive and specific tool for clinical and pre-clinical investigations.HighlightsMass spectrometry method simultaneously quantifies multiple cardiotonic steroidsAccurate and specific measurement of clinically relevant digoxin concentrationMethod validated for measurement of cardiotonic steroids in serum and plasmaPost-column infusion of lithium chloride substantially improves sensitivityResearch fundingThis work was funded by the British Heart Foundation (PG/17/55/33087, FS/PhD/22/29309, FS/19/12/34204, RG/17/15/33106 to DP, Accelerator Award AA/18/2/34218 to Institute of Cardiovascular Sciences), Wellcome Trust (Seed Award Grant 109604/Z/15/Z to DP) and Department of Clinical Laboratory Sciences, Faculty of Applied medical Sciences, University of Hail.

“…In this part, PHT, PHB, or LTG reference solution at the concentration of 3 levels was spiked in methanol, NS, PBS, and rat blank plasma to simulate the practical chemical industry samples, environmental water, urine, and plasma, respectively. 40,41 Extraction experiments of the target analytes in different matrices were carried out to investigate the practical application of MIPMs. It was noted that in this study, the plasma sample needed to be diluted by 4 times with PBS before treatment with MIPMs, while the other matrices sample could be treated with MIPMs directly.…”
