Der volle Inhalt der QuelleAnticoagulant rodenticides (AR) are an essential tool for controlling rodent pests. The environmentally responsible use of AR tends to limit the exposure of non-target species. No study on the prevalence of AR in animals has been conducted in Tunisia. Therefore, a first toxicological survey showed that AR are incriminated as one of the most frequent causes of acute AR poisoning in dogs. Moreover, in another study, we reported that natural anticoagulants, such as ferulenol produced by Ferula communis can cause heavy losses to local farmers. Few studies have focused on the toxicokinetics of AR. To monitor these exposure rates, the validation of the appropriate biological matrix is essential and is a major guarantee of the robustness of the analytical method. The liver is the storage tissue for AR and is the best sample for assessing exposure in animals. However, it is only available from dead animals. Blood and feces can be used from live animals. We studied the comparison of the three matrices (liver, blood, and feces), considering three influencing factors: dose, sex, and time. Our results show that fecal samples are more valuable than plasma samples for monitoring AR exposure in domestic and wild animals. The clinical symptoms of acute AR poisoning are dramatic, but low-dose exposures go unnoticed and present insidious deleterious health effects. Asymptomatic exposure of domestic animals to AR is poorly documented. Our study showed limited prevalence in dogs and cats, in contrast to other work where prevalence in wildlife predators is much higher from analyses performed on the livers of opportunistically dead animals, without considering the healthy ones. This work could generate ideas for new analytical strategies. It would allow better addressing toxicokinetic and toxicodynamic properties in other non-target species as part of the development of new, more eco-friendly AR molecules

Der volle Inhalt der QuelleSeveral publications brought to light the crucial impact of CYP2C9 and more recently VKORC1 genotypes to predict dose anticoagulant requirement and thus to prevent frequent complications (including bleeding). We reported that CYP2C9 and VKORC1 genetic variations account for 50% of the drug response variability after acenocoumarol intake and showed that haplotypic study of VKORC1 was not more informative than a single SNP, corresponding to the –1639G>A promoter variation. New dosing algorithms should incorporate a single SNP (–1639G>A) and be assessed rapidly in prospective studies to help clinical settings to individualize of warfarin dose. It would be of high interest for physicians to predict about 50% of the inter-individual variability of the coumarin response by the genotyping of two SNPs, CYP2C9*3 and –1639 G>A on the VKORC1 gene

Der volle Inhalt der QuelleOral anticoagulant treatment (OAT) is widely used in therapy. Each year, nearly 900 000 french patients are estimated to be treated by OAT. The benefit of the anticoagulant treatment is well-established in various cardiovascular diseases. In France, the national network of regional pharmacovigilance centres ran a study during 1998. The bleeding complications due to the OAT were the first cause of adverse drug reactions leading to a hospitalization. Until now, all the recommendations have not succeeded in significantly change the clinical practice. A new study led during 2007 confirmed that bleeding complications due to OAT were always at the first line of the adverse drug reaction risk. The OAT is difficult to handle. In fact, this is due to a narrow therapeutic safety zone and to a great variability of the response to the treatment in individuals and between individuals. Many risk factors play a part in this variability. In this study, we tried to identify the risk factors mostly involved in the bleeding complications. First, the INR was essential for the monitoring of the OAT. The targets must be first and foremost the keeping in the therapeutic range, the regular follow up and the physician adaptability to an overdosage. The other factors put forward were: a chronic alcoholism, a trauma, recent digestive lesions, a prescription not complying with the marketing authorization application, a simultaneous treatment (acetaminophen, allopurinol or heparin), a patient mistake in taking the drug and a lack of therapeutic compliance. Some of the cases suggested that a part of the bleeding could be linked to insufficiently rigorous anticoagulation practices. The findings were that anticoagulation was not optimal in a great proportion of patients. From this point, by adapting a published score, it was attempted to quantify the part allocated to the preventability of bleeding events of this study. This assessment showed that 50 to 65% of these events could be totally avoided or potentially avoided by a more rigorous management of the OAT. Faced with such findings, all the concerned health providers (physicians, chemists, biologists, nurses …) must be aware to the issue. They must make their practices evolved mainly in terms of health care coordination, in terms of information and in terms of therapeutic education of the patient. In this way, the communication aiming at making all the health providers aware of the issue should be carried on. Anyway, until we get other solutions, the OAT must be thoughtfully prescribed individually. The expected benefit (indication) and the potential risk (bleeding events above all) itself linked to the background (co morbidity), to the concomitant ailments and to the patients (concomitant treatments, compliance), must be taken into account. The biological follow up must be close. The benefit /risk ratio must be assessed no less than annually. Under these conditions, the quality of the patient management should improve and lead to the decreasing of the iatrogenic risk due to OAT

Der volle Inhalt der QuelleDirect oral anticoagulants (DOAC) were gradually introduced since 2012 in France for stroke and systemic embolism prevention in patients with nonvalvular atrial fibrillation (AF), as a more convenient alternative to vitamin K antagonists (VKA) for which underprescribing and high rates of discontinuation have been frequently reported. As part of the work programme of the Department of Studies in Public Health, French National Health Insurance, the aim of this dissertation was to assess the patterns of use and safety of oral anticoagulant (OAC) therapy in real-life setting using the French healthcare databases. First, an algorithm was developed to identify AF in outpatients initiating OAC and for whom no diagnosis of AF was found in the French claims data. Second, 1-year dabigatran and rivaroxaban adherence rates were estimated in nonvalvular AF patients and 1-year non-persistence rates were compared versus VKA. At least 1 in 3 dabigatran or rivaroxaban new users was found to be non-adherent to treatment. Treatment persistence among dabigatran or rivaroxaban new users was not found to be better versus VKA therapy. Third, OAC therapy use was found to have increased following in France between 2011 and 2016 but remained suboptimal with 1 in 3 patients with AF not treated by OAC therapy. Several situations of inappropriate use of DOAC were identified including potential undertreatment by inappropriate dosing. Finally, a sequence symmetry analysis suggested that DOAC therapy is associated with rare but severe liver injury and more frequent gastrointestinal disorders. A low risk of kidney injury with DOAC therapy can also not be excluded. These findings advocate further investigation of the potential risk of DOAC underdosing at initiation and the continuous monitoring of the non-bleeding adverse events of DOAC therapy

Der volle Inhalt der QuellePharmacologic issues of anticoagulant treatments in elderly patients may explain the specific clinical management in Geriatrics. This work reports clinical studies conducted specifically in elderly patients treated with LMWH or VKA. The first part concerns mainly the development and the multicentric validation of a warfarin induction regimen specifically designed for elderly patients. The influence of pharmacogenetic and environmental factors on the anticoagulant response to warfarin in elderly patients are discussed in original articles or reviews that we published. The second part concerns LMWH. The main issue with their use in this population arises from the age-related renal failure. Since LMWH are mainly excreted by the kidney, there is a risk of accumulation of the drug in elderly patients. Studies assessing the accumulation of LMWH in elderly patients are reported. Finally, the clinical relevance of our pharmacologic data is discussed
