AbstractBackground: Thrombin generation testing has been used to provide information on the coagulation phenotype of patients. The most used technique is the calibrated automated thrombogram (CAT) but it suffers from a lack of standardization, preventing its implementation in routine. The ST Genesia is a new analyzer designed to assess thrombin generation based on the same principle as the CAT. Unlike the CAT system, the ST Genesia is a benchtop, fully automated analyzer, able to perform the analyses individually and not by batch, with strict control of variables such as temperature and volumes, ensuring, theoretically, maximal reproducibility. Objectives:This study aimed at assessing the performance of the STG-DrugScreen application on the ST Genesia analyzer. We also aimed at exploring stability of plasma samples after freezing and defining a reference normal range. Results:Results demonstrated the excellent interexperiment precision of the ST Genesia and confirmed that the use of a reference plasma helps reducing the

Inappropriate use of DE and rivaroxaban in patients with NVAF is frequent and possibly leads to AEs. Reinforcing education of health care professionals and patients is needed. Collaboration with clinical pharmacists can contribute to better use.

In patients not bridged with LMWH, we suggest to use the Biophen DiXaI LOW and STA LAX for the estimation of rivaroxaban concentrations <50 ng/mL. These results should be confirmed on a larger cohort of patients. Patients bridged with LMWH have inaccurate estimates of low levels of rivaroxaban and the 3 assays studied should not be used to estimate if it is safe to perform a procedure.

More than half of serious ADRs were potentially preventable for both DOACs and VKAs. Interventions focusing on prescribing, patient education and continuity of care should help improve the use of DOACs in practice.

Idarucizumab is a specific antagonist for dabigatran etexilate (DE). The recent market authorization of idarucizumab in Europe and the USA may reassure prescribers of DE, as it can increase the safety of the emergency management of patients taking this anticoagulant. However, idarucizumab use should be limited to specific indications to avoid unnecessary risks to patients and costs to healthcare systems. Areas covered: The authors provide an overview of idarucizumab development and its pharmacokinetic and pharmacodynamic properties. The results of the clinical phase III trial RE-VERSE AD and a review of recent case reports of idarucizumab use in emergency contexts are also discussed. Expert opinion: Although idarucizumab has shown clear efficacy in reversing dabigatran-induced coagulopathy, its overall effects on patient outcome have not been proven. Information regarding the clinical context in which patients on DE are admitted for emergency treatment, and accurate laboratory tests of dabigatran plasma level during reversal may inform selection and help with the follow-up of patients who may benefit from idarucizumab. Idarucizumab should be integrated into protocol for the emergency management of patients on DE. Furthermore, the benefit of idarucizumab in specific indications such as acute ischemic stroke should be investigated.
