ABSTRACT The ecarin clotting time (ECT) is a meizothrombin generation test that allows for precise quantification of direct thrombin inhibitors. The ECT has demonstrated its usefulness for more than 10 years in biochemical-pharmacological investigations as well as in clinical research and in the clinical routine. It has proved valuable especially as a drug-monitoring method in r-hirudin therapy. This test has been adjusted to clinical requirements by numerous modifications. Following the description of the biochemical background and the measuring principle of the ECT, this article gives a short survey of several modifications of the ECT for both preclinical and clinical use, e.g., for biochemical investigations, as a point-of-care method and for cardiac surgery. Advantages and disadvantages of these methods are discussed.

    ABSTRACT: Oral anticoagulants are now available with predictable pharmacokinetic and pharmacodynamic profiles, therefore eliminating the need for routine therapeutic monitoring. There are a number of clinical scenarios in which the ability to measure the pharmacodynamic and pharmacologic activity of these agent would be desirable. Since these new oral anticoagulants do not impact traditional coagulation assays like warfarin or heparins, and impact the assays differently among agents, measuring and monitoring creates a challenge for clinicians who care for these patients in the emergency or hospitalized setting. Understanding the effect of these agents, the available assays, and the interpretation of results is an element of their safe and effective use.

    ABSTRACT: Dabigatran etexilate is an oral direct thrombin inhibitor. Although routine anticoagulation monitoring with dabigatran is not usually required, a simple and precise laboratory test to measure dabigatran concentrations in patient plasma may be useful in certain clinical circumstances, such as emergency situations. The HEMOCLOT(®) Thrombin Inhibitors assay has demonstrated accurate and precise determination of dabigatran concentrations within a range of 50-500ng/ml. The objective of this study was to assess comparability of dabigatran concentrations determined by HEMOCLOT(®) and by liquid chromatography/tandem mass spectrometry (LC-MS/MS) in plasma samples from human volunteers with end-stage renal disease (ESRD) undergoing regular haemodialysis (HD) during a Phase I study. Overall, 304 plasma samples were obtained from seven ESRD patients in dabigatran steady-state for measurement by HEMOCLOT(®) (calibrated diluted thrombin time [dTT]) and by LC-MS/MS. Agreement of dabigatran concentrations was assessed by regression analysis and difference plots. The measurements of calibration standards of the HEMOCLOT(®) assay showed excellent precision with coefficients of variation <5%. Accuracy determined by analysis of two quality control samples was 90% and 111%. HEMOCLOT(®)-derived dabigatran plasma concentrations paralleled those obtained by LC-MS/MS. The mean ratio of the LC-MS/MS and dTT-derived concentrations was 0.955 (67% limits of agreement: 0.771-1.18). The HEMOCLOT(®) Thrombin Inhibitors assay is suitable for measuring dabigatran plasma concentrations in volunteers with ESRD undergoing haemodialysis. The agreement between dabigatran concentrations determined by the HEMOCLOT(®) assay and the LC-MS/MS reference method met bioanalytical acceptance criteria. Copyright © 2014.

    ABSTRACT: Non-VKA oral anticoagulants (NOACs) have now widely reached the lucrative market of anticoagulation. While the marketing authorization holders claimed that no routine monitoring is required and that these compounds can be given at fixed doses, several evidences arisen from the literature tend to demonstrate the opposite. New data suggests that an assessment of the response at the individual level could improve the benefit-risk ratio of at least dabigatran. Information regarding the association of rivaroxaban and apixaban exposure and the bleeding risk is available in the drug approval package on the FDA website. These reviews suggest that accumulation of these compounds increases the risk of experiencing a bleeding complication. Therefore, in certain patient populations such as patients with acute or chronic renal impairment or with multiple drug interactions, measurement of drug exposure may be useful to ensure an optimal treatment response. More specific circumstances such as patients experiencing a haemorrhagic or thromboembolic event during the treatment duration, patients who require urgent surgery or an invasive procedure, or patient with a suspected overdose could benefit from such a measurement. This paper aims at providing guidance on how to best estimate the intensity of anticoagulation using laboratory assays in daily practice.
