Abstract
Introduction Recent reviews on patients’ preferences towards attributes of oral anti-coagulant therapy have shown that preference for convenience of therapy is heterogeneous. In this study, we used a novel approach—latent class analysis (LCA)—to assess heterogeneity. Methods We developed a health preference survey that consisted of 12 discrete choice questions. The following attributes of convenience were included: intake frequency; need for regular coagulation monitoring; diet or drug interactions; relation between medication and food intake; and pill type. Background questions about gender, age, current therapy [i.e., direct-acting oral anti-coagulant (DOAC) or vitamin K antagonist (VKA)], self-reported medication adherence, and pill burden were included. Mixed logit analysis (MLA) and LCA were performed. The scale-adjusted LCA model with two scale classes and four preference classes emerged as the model with the best fit and interpretability. Results A total of 508 patients with non-valvular atrial fibrillation from five European countries (Germany, Italy, Spain, France, and the UK) were surveyed in August 2017. The most important attributes were need for monitoring (37%) and intake frequency (27%). Patient preferences were significantly influenced by country, gender, and current anti-coagulant therapy. Four different preference classes of patients were identified in the LCA. First, most patients (57%) were in the “no need for regular coagulation monitoring” class. Current DOAC users and patients who were the least adherent to therapy were more likely to prefer no coagulation monitoring. Second, 20% of patients were in the “balanced” class of patients. Current VKA users with moderate adherence were more likely to be in this class. Patients who reported the lowest adherence were most likely in the “once daily, interactions likely” class (16%). Fourth, current VKA users and highly adherent patients were most likely to prefer therapies with a need for regular coagulation monitoring (7%). Conclusions This study demonstrated significant preference heterogeneity among patients with atrial fibrillation and linked these preferences to differences in background characteristics. Country of residence and currently prescribed therapy influenced patient preferences in both the MLA and LCA models.

Interindividual Variability of Apixaban Plasma Concentrations: Influence of Clinical and Genetic Factors in a Real-Life Cohort of Atrial Fibrillation Patients. Genes (Basel) 2020; 11:genes11040438. [PMID: 32316515 PMCID: PMC7230214 DOI: 10.3390/genes11040438] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 04/03/2020] [Accepted: 04/14/2020] [Indexed: 02/06/2023] Open
Abstract
(1) Background: Prescribing apixaban for stroke prevention has significantly increased in patients with non-valvular atrial fibrillation (NVAF). The ABCB1 genotype can influence apixaban absorption and bioavailability. The aim of the present study was to assess the factors that influence apixaban’s plasma level and to establish if a certain relationship has clinical relevance. (2) Methods: Fifty-three NVAF patients were treated with 5 mg apixaban twice/day (70.0 years, range: 65–77, 60.4% men). Trough and peak plasma concentrations of apixaban were determined by liquid chromatography-tandem mass-spectrometry (LC-MS/MS), and ABCB1 genotyping was performed. (3) Results: Apixaban plasma concentrations varied considerably. They were higher in women than in men (311.2 ng/dL vs. 252.2 ng/dL; p = 0.05) and were lower in patients with heart failure (149.4 ng/dL vs. 304.5 ng/dL; p < 0.01). Creatinine clearance was inversely correlated with the apixaban plasma level (Spearman correlation: r = −0.365; p = 0.007 for trough concentrations). No statistically significant differences between the genotypic groups of ABCB1 rs1045642 and ABCB1 rs4148738 were found in the trough or peak apixaban plasma concentrations. (4) Conclusions: Pharmacokinetic parameters are influenced by several clinical factors of which renal function is the major determinant. Plasma concentrations measured in women had higher values than those measured in men, and heart failure was associated with decreased plasma levels of apixaban.

Non-Vitamin K Oral Anticoagulants (NOAC) Versus Vitamin K Antagonists (VKA) for Atrial Fibrillation with Elective or Urgent Percutaneous Coronary Intervention: A Meta-Analysis with a Particular Focus on Combination Type. J Clin Med 2020; 9:jcm9041120. [PMID: 32295160 PMCID: PMC7230168 DOI: 10.3390/jcm9041120] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Revised: 04/03/2020] [Accepted: 04/07/2020] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Our study aims to perform a meta-analysis of benefits and risks associated with the use of non-vitamin K oral anticoagulants (NOAC) versus vitamin K antagonists (VKA) in patients with a percutaneous coronary intervention (PCI) with a particular focus on the combination type: dual vs. dual antithrombotic therapy (DAT: NOAC + single antiplatelet therapy (SAPT) vs. DAT: VKA + SAPT), dual vs. triple antithrombotic therapy (DAT: NOAC + SAPT vs. TAT: VKA + dual antiplatelet therapy (DAPT)) or triple vs. triple antithrombotic therapy (TAT: NOAC+DAPT vs. TAT: VKA+DAPT). METHODS PubMed, EMBASE, and Cochrane databases were searched to identify randomized controlled trials comparing antithrombotic regimens. Four randomized studies (n = 10.969; PIONEER AF-PCI, RE-DUAL PCI, AUGUSTUS, and ENTRUST-AF PCI) were included. The primary outcome was the composite of major bleeding defined by the International Society on Thrombosis and Hemostasis (ISTH) and clinically relevant bleeding requiring medical intervention (CRNM). Secondary outcomes included all-cause mortality, major adverse cardiovascular events (MACE), myocardial infarction (MI), stroke, and stent thrombosis (ST). RESULTS Combination strategies with NOACs were associated with reduced risk of major bleeding events across different combination strategies as compared to VKA, with the most significant risk reduction when DAT was compared with TAT, namely DAT with NOAC + SAPT was associated with a 37% relative risk reduction (RRR) of major bleeding events as compared to TAT with VKA + DAPT (RR 0.63; 95% CI, 0.50-0.80). The reduction of major bleeding risks is a class effect of NOACs. Combination strategies of NOACs vs. VKAs resulted in a comparable risk of MACE, MI, stroke, ST, or death. CONCLUSIONS Antithrombotic combinations of NOACs (as DAT or TAT) are safer than VKAs with respect to bleeding risk and result in a satisfactory efficacy with no increase of ischemic or thrombotic events in patients undergoing PCI.

Diagnostic value of N-terminal pro B-type natriuretic peptide for nonvalvular atrial fibrillation in acute ischemic stroke patients: A retrospective multicenter case-control study. J Neurol Sci 2020; 414:116822. [PMID: 32278166 DOI: 10.1016/j.jns.2020.116822] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 04/03/2020] [Accepted: 04/03/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The detection of Nonvalvular atrial fibrillation (NVAF) in AIS patients may be elusive and require further investigation such as electrocardiography (ECG) and Holter monitoring. The objective of this study is to evaluate the N-terminal pro B-type natriuretic peptide (NT-proBNP) diagnostic value for NVAF and the clinical outcome of AIS patients. METHODS We conducted a retrospective study of AIS patients in ten hospitals of the Shaanxi province. All NVAF patients and matched patients without NVAF admitted within 7 days after stroke onset were included in our study. The admission NT-proBNP receiver operating characteristic curve was drawn to determine the discriminative power of NT-proBNP in NVAF identification. Multivariate logistic regression analysis was used to examine the odds ratios (OR) of NT-proBNP for NVAF and identify the potential factors associated with the clinical outcomes in AIS patients. RESULTS A total of 275 NVAF cases and 275-matched controls were included in the current study. NT-proBNP was independently associated with NVAF (OR = 64.047, 95% confidence interval [CI]: 30.298-135.390, p < .001) in AIS patients. The optimal cutoff point for the NT-proBNP level to distinguish the NVAF group from the non-NVAF group was 431.0 pg/ml, with an area under curve [AUC] of 0.910 (95% CI: 0.885-0.935, p < .001). The high NT-proBNP level (OR: 3.284, 95% CI: 1.830-5.896, p < .001) was an independent indicator that was positively related to hospitalization mortality. CONCLUSION The rise of the serum NT-proBNP level at first admission added great contributions to the NVAF diagnosis after AIS, and was independently associated with the hospitalization mortality of AIS patients.

Boursier-Bossy V, Zuber M, Emmerich J. Ischemic stroke and non-valvular atrial fibrillation: When to introduce anticoagulant therapy? JOURNAL DE MEDECINE VASCULAIRE 2020; 45:72-80.

Abstract
About 20 to 30% of ischemic strokes are related to non-valvular atrial fibrillation. This type of situation is particularly at risk for both recurrence of the ischemic event and the hemorrhagic transformation of this stroke. The timing of the introduction or going back to the anticoagulant therapy in these patients remains a difficult issue, with a complex benefit-risk balance that needs to be assessed. Randomized controlled studies are lacking and current recommendations do not allow for clear decision making. The administration of a curative anticoagulant within 72 hours after the event is not recommended in the absence of demonstrated efficacy in preventing recurrence at this stage and because of the risk of intracerebral hemorrhage. This attitude can nevertheless be qualified by a transient accident or ischemic accident of very small size, and in the absence of any other risk factor for intra- or extra-cerebral hemorrhage. From the 4th day, after an appropriate case by case evaluation, the introduction of anticoagulant would be possible within a time which will remain at the appreciation of the medical teams. If the patient's risk of an intracerebral hemorrhage or general bleeding is transiently increased, it will be preferable to wait at least 2 weeks after the stroke. If this risk persists in the long term, the decision of the administration or not of an anticoagulant will have to be made with a multidisciplinary consultation. Vitamin K antagonists or direct oral anticoagulants may be prescribed as first-line therapy for the prevention of recurrence of ischemic stroke in a non-valvular atrial fibrillation patient. The choice will be based on the clinical and biological data of each patient. Direct oral anticoagulants have not shown superiority in the prevention of ischemic recurrence but open up new prospects for earlier treatment if their lesser risk of bleeding is confirmed after further studies.

Abstract
BACKGROUND This position paper highlights the opportunistic integral role of the pharmacist across the patient pathway utilizing cardiovascular care as an example. The paper aims to highlight the potential roles that pharmacists worldwide can have (or already have) to provide efficient patient care in the context of interprofessional collaboration. METHODS It results from a literature review and experts seeking advice to identify existing interventions and potential innovative interventions. We developed a conceptual framework highlighting seven critical phases in the patient pathway and for each of those listed some of the initiatives identified by our experts worldwide. RESULTS Existing pharmacists' interventions in each of these phases have been identified globally. Various examples in the area of prevention and self-management were found to exist for long; the contribution for early detection and subsequently to timely diagnosis were also quite clear; integration of care was perhaps one of the areas needing greater development, although interventions in secondary care were also quite common. Tertiary care and end of life interventions were found to often be left for other healthcare professionals. CONCLUSION On the basis of the findings, we can argue that much has been done but globally consider that pharmacists are still an untapped resource potentially useful for improved patient care.

Abstract
Aim To evaluate frequency of administration of anticoagulant therapy (ACT) for atrial fibrillation and to study the effect of chronic antithrombotic therapy (ATT) on kidney function.Material and methods Due to a high medical and social significance of AF, much attention is presently paid to appropriate administration of ACT for AF in clinical practice. The study retrospectively analyzed 776 case reports of hospitalized patients with AF. The effect of chronic ATT on kidney function was studied in 70 patients who were rehospitalized, including 25 patients treated with warfarin, 25 patients treated with direct oral anticoagulants (DOAC), and 20 patients treated with acetylsalicylic acid (ASA).Results In January 2014, at the prehospital stage, 74.3 % of patients did not receive ATT, 14.7 % of patients received antiplatelet therapy, and only 11 % received anticoagulants. In the hospital in January 2014, ACTs were administered to 74.3 % of patients (warfarin, 58.6 %; DOAC, 15.7 %), 20.6 % of patients received antiplatelet drugs, and 5.1 % of patients were discharged without ATT. In January 2019, the number of patients receiving ACT at the prehospital stage increased to 58.1 % (warfarin, 13.8 %; DOAC, 44.3 %); 12 % of patients received antiplatelet drugs; and 29.9 % of patients did not receive ATT. The number of patients treated with warfarin and DOAC in the hospital increased to 14.8 % and 70.6 % (rivaroxaban, 33.4 %; apixaban, 25.5 %, and dabigatran, 11.7 %), respectively. The number of patients taking antiplatelet drugs decreased to 3.7 %, and the number of patients without ATT decreased to 10.9 %. There were no statistically significant differences in glomerular filtration rate (GFR) between these three groups at baseline. Only in the warfarin treatment group, GFR was significantly decreased from baseline during the follow-up period. Comparison of GFR in three study groups at the finale stage of the study showed significant differences between mean GFRs in the warfarin treatment group and the DOAC treatment group and between the warfarin treatment group and the ASA treatment group.Conclusion Among the prescribed and taken anticoagulants, DOACs are presently in the first place. Among DOACs, the most frequently prescribed drug is rivaroxaban. GFR decreases with the DOAC treatment slower than with the warfarin treatment. Despite the slower decrease in GFR with the ASA treatment compared to warfarin, ASA is not indicated for prevention of stroke in AF due to its low efficacy.

Abstract
Background: Therapy with oral anticoagulation (OAC) can be challenging, especially in high risk groups such as chronic patients. Gaps in patient knowledge about OAC are linked to reduced effectiveness and safety of treatment. The objectives of this study were i) to assess OAC knowledge gathered during an intermediate medication review (MR) in patients taking vitamin K antagonists (VKA) or non-vitamin K antagonist oral anticoagulants (NOAC); ii) to assess OAC knowledge two weeks after the MR, and iii) to evaluate patient satisfaction with the MR service in community pharmacies. Methods: Chronic OAC patients were invited for a regular MR service in Swiss community pharmacies, the so-called “Polymedication-Check” (PMC). OAC knowledge was assessed with seven newly generated items asked face-to-face during a PMC and by telephone two weeks later. Knowledge gaps, pharmacists’ spontaneous interventions, and patient satisfaction were documented by observing pharmacy students. Treatment groups were compared. Results: Of all patients (n = 81), the number of patients with one or more knowledge gaps decreased from 66% to 31.3% after PMC (p < 0.001). NOAC patients (n = 31) had more knowledge gaps than VKA patients (n = 50; p < 0.05). Most patients (98.6%) were satisfied with the counselling provided by the pharmacists. Conclusion: The majority of chronic OAC patients shows knowledge gaps. Although spontaneous, the provision of tailored education during a PMC increased patient OAC knowledge.

Abstract
Despite its clinical relevance, cerebral amyloid angiopathy (CAA) is underdiagnosed worldwide. This retrospective study aimed to assess the incidence, etiology, predictors, and outcome of intracerebral hemorrhages (ICHs) in this region, with special focus on possible underlying CAA. Database screening of acute cares with intracranial hemorrhage diagnosis within 01/07/2014–01/07/2018 were conducted analyzing medical records and imaging. Spontaneous ICHs were classified as deep (basal ganglionic/thalamic/brainstem) and lobar/cerebellar (i.e., CAA-compatible) ICHs. Probable/definite CAA was established using the modified Boston criteria in a subgroup with ‘complete’ radiological/neuropathological work-up. The ability of several factors to discriminate between deep and lobar/cerebellar ICHs, between probable/definite CAA and non-probable CAA cases, and to predict 1-month case fatality was assessed. Of the 213 ICHs identified, 121 were in deep and 92 in lobar/cerebellar localization. Sub-analysis of 47 lobar/cerebellar ICHs with ‘complete’ work-up identified 16 probable/definite CAA patients, yielding an estimated 14.7% prevalence of CAA-related ICHs. Chronic hypertension was the most prevalent risk factor for all types of ICHs (including CAA-related), with hypertensive excess and younger age being independent predictors of deep whereas antiplatelet use of lobar/cerebellar localization. The 1-month case fatality was 33.8%, driven predominantly by age and INR > 1.4. Probable/definite CAA diagnosis was independently predicted by age, prior intracranial hemorrhage, and antiplatelet use. First in this region and among the few in the literature, this study reports a remarkable prevalence of CAA-related ICHs, emphasizing the need for an increased awareness of CAA and its therapeutic implications, especially regarding antiplatelets among the elderly.

Abstract
Factor Xa (FXa) inhibitors are recommended for use in fixed doses without laboratory monitoring. However, prior studies reported the importance of establishing biomarkers representing anticoagulation intensity related to bleeding or thrombotic events. To test the hypothesis that prothrombin activation fragment 1 and 2 (F1 + 2), a non-specific marker of thrombin generation, could be altered during FXa inhibitor treatment in patients with atrial fibrillation. We conducted the study in two different clinical settings. First, the interrelations among biomarkers representing coagulation/fibrinolysis were investigated in 80 patients in an outpatient clinic. Second, these biomarkers were evaluated in 75 patients who underwent radiofrequency catheter ablation. Plasma concentration of FXa inhibitors was evaluated using an anti-FXa chromogenic assay (C-Xa). In the outpatient study, only F1 + 2 exhibited a significant and negative association with C-Xa (rS = - 0.315, p = 0.026), and 37% of the variance could be explained by C-Xa levels. F1 + 2 levels above the reference range (> 229 pmol/L) could be considered as a cut-off to identify poor patient compliance or under-dosing. In the peri-ablation study, increased F1 + 2 levels were associated with decline of C-Xa levels after periprocedural discontinuation of FXa inhibitors, which was greater in the rivaroxaban group than in the apixaban group. F1 + 2 showed modest and inverse association with plasma concentration of rivaroxaban and apixaban in patients with atrial fibrillation. Larger study to test the hypothesis that continued thrombin generation despite anticoagulation is associated with a heightened risk of clinical events is required.

Abstract
Recurrent stroke is a frequent event and clinical trials that addressed the best secondary prevention are sparse. If patients take a thrombocyte aggregation inhibitor (TAI) before the recurrent stroke, clopidogrel can be chosen instead of aspirin or vice versa but evidence is lacking. A 3-week period of dual antiplatelet treatment might be a good alternative after acute reinfarction. The results of the recently published RESTART trial support resuming TAI treatment after a hemorrhagic stroke and showed that the intracerebral hemorrhage (ICH) rate is not elevated in comparison with a study group without TAI. Patients with ICH associated with oral anticoagulation (OAC) and atrial fibrillation should be restarted on novel OACs, if there are no relevant contraindications and the risk of ischemia is high. The anticoagulation treatment of patients with cerebral amyloid angiopathy is still a clinical dilemma as there is a high risk of recurrent ICH. These patients might be candidates for left appendage closure.

Abstract
OBJECTIVE The difficulty in diagnosis and the spectrum of clinical manifestations that can determine the choice of treatment for antiphospholipid syndrome (APS) has fostered the development of recommendations by the Spanish Society of Rheumatology (SER), based on the best possible evidence. These recommendations can serve as a reference for rheumatologists and other specialists involved in the management of APS. METHODS A panel of 4rheumatologists, a gynaecologist and a haematologist with expertise in APS was created, previously selected by the SER through an open call or based on professional merits. The stages of the work were: identification of the key areas for the document elaboration, analysis and synthesis of the scientific evidence (using the Scottish Intercollegiate Guidelines Network, SIGN levels of evidence) and formulation of recommendations based on this evidence and formal assessment or reasoned judgement techniques (consensus techniques). RESULTS Forty-six recommendations were drawn up, addressing 5main areas: diagnosis and evaluation, measurement of primary thromboprophylaxis, treatment for APS or secondary thromboprophylaxis, treatment for obstetric APS and special situations. These recommendations also include the role of novel oral anticoagulants, the problem of recurrences or the key risk factors identified in these subjects. This document reflects the last 25, referring to the areas of: obstetric APS and special situations. The document provides a table of recommendations and treatment algorithms. CONCLUSIONS Update of SER recommendations on APS is presented. This document corresponds to part II, related to obstetric SAF and special situations. These recommendations are considered tools for decision-making for clinicians, taking into consideration both the decision of the physician experienced in APS and the patient. A part I has also been prepared, which addresses aspects related to diagnosis, evaluation and treatment.

[PMID: 32022295 PMCID: PMC7256117 DOI: 10.1111/bcp.14227] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 12/28/2019] [Accepted: 12/31/2019] [Indexed: 12/11/2022] Open
Abstract
Aims To assess the association between concurrent use of potential pharmacokinetic or pharmacodynamic interacting drugs and major bleeding among direct oral anticoagulant (DOAC) users. Methods We performed a case–control study nested in a cohort of new users of DOACs (dabigatran etexilate, apixaban or rivaroxaban). Data were obtained from the UK Clinical Practice Research Datalink linked to Hospital Episode Statistics (2008–2015). Cases were patients hospitalized having a primary diagnosis of major bleeding. Up to 4 controls were matched on age, sex, index date and region. Odds ratios (ORs) for the risk of major bleeding were assessed by conditional logistic regression analysis and adjusted for well‐known covariates for the risk of bleeding. Results We identified 393 patients with a major bleeding from a total of 23 492 new users of DOACs and 1494 matched controls. Most subjects were users of rivaroxaban (58.8%) on the index date. The concurrent use of pharmacodynamic interacting drugs was associated with an increased risk of major bleeding (21.6% of cases vs 13.5% of controls, adjusted odds ratio [aOR] 1.92; 95% confidence interval [CI], 1.40–2.66). For the antiplatelet drugs the aOR was 2.01 (95% CI, 1.29–3.11) and for the selective serotonin reuptake inhibitors the aOR was 1.68 (95% CI, 1.10–2.59). We found no increased risk of major bleeding for concurrent use of pharmacokinetic interacting drugs vs DOACs alone (45.0 vs 51.2%; aOR: 0.77; 95% CI: 0.53–1.10). Conclusion Among patients taking DOACs the concurrent use of antiplatelet drugs or selective serotonin reuptake inhibitors was associated with increased risk of major bleeding, while pharmacokinetic interacting drugs do not increase this risk.

Abstract
Guidelines and experts note that patients with atrial fibrillation require regular renal function monitoring to ensure safe use of direct oral anticoagulants (DOACs). Insufficient monitoring could lead to inappropriate dosing and adverse events. Our objective was to describe the frequency of insufficient creatinine monitoring among patients on DOACs, and to describe clinical factors associated with insufficient monitoring. We hypothesized that renal impairment would be associated with insufficient monitoring. A retrospective cohort study was performed with data from the Michigan Anticoagulant Quality Improvement Initiative. Patients were included if they initiated DOAC therapy for stroke prevention related to atrial fibrillation, remained on therapy for ≥ 1 year, and had baseline creatinine and weight measurements. Creatinine clearance (CrCl) was calculated via Cockcroft-Gault equation. Our outcome was the presence of insufficient creatinine monitoring, defined as: < 1 creatinine level/year for patients with CrCl > 50, or < 2 creatinine levels/year for patients with CrCl ≤ 50. Multivariable analysis was done via logistic regression. Study population included 511 patients. In overall, 14.0% of patients received insufficient monitoring. Among patients with CrCl > 50, 11.5% had < 1 creatinine level/year. Among patients with CrCl ≤ 50, 27.1% received < 2 creatinine levels/year. Baseline renal dysfunction was associated with a higher likelihood of insufficient creatinine monitoring (adjusted odds ratio 3.64, 95% confidence interval 1.81-7.29). This shows a significant gap in the monitoring of patients on DOACs-patients with renal impairment are already at higher risk for adverse events. Future studies are needed to describe the barriers in monitoring these patients and to identify how to optimally address them.

Abstract
OBJECTIVE To identify timing for initiation of anticoagulation therapy in acute ischemic stroke (AIS) with non-valvular AF as regards safety and efficacy by detecting the rate of intracranial haemorrhage (ICH) and recurrent ischemic symptoms (RIS) during follow-up. METHODS This is a prospective observational cohort study conducted at King Fahd Hospital of the University including 120 patients with AIS/TIAs from July 2016 till July 2018. We compared patients who received anticoagulants 1-6 days (Group I (45.83%), 7-14 days, Group II (35%), and > 14 days after the ischemic event (Group III (19.17%). Follow-up was at least 3 months and included identifying ICH or RIS. RESULT ICH has occurred in 26.67% (n = 32) patients with a highly statistically significant association with time of treatment (P-value = .01) being higher in group I (n = 17) compared to only 1 case in group III. Subgroup analyses on the ICH patients (n = 32) has revealed statistical significant association with higher NIHSS score (P = .001). Also, the type of anticoagulants used between three groups pointed to an association existence (p = .02), however, the direction of this association cannot be determined. There was no statistical significant association between RIS (occurred in 4.16% (n = 5) with time of treatment (P = .754). Functional outcome at 3-6 months measured by mRS did not differ between 3 groups (worst mRS in group I). CONCLUSION Early initiation of anticoagulation after stroke, especially in cases of large infarction, is associated with significant risk of ICH. This risk is highest with warfarin and lowest with DOAC.

Abstract
Abstract
Purpose
Dose reduction of non-vitamin K antagonist oral anticoagulants (NOACs) is indicated in patients with atrial fibrillation (AF) with renal impairment. This study investigated anticoagulation patterns and outcomes in patients with chronic kidney disease (CKD).
Materials and methods
In a prospective observational registry (CODE-AF), 3445 patients with non-valvular AF including 1129 with CKD (estimated glomerular filtration rate ≤ 60 mL min−1 1.73 m−2) were identified between June 1, 2016, and July 3, 2017.
Results
Compared with patients with no-CKD, patients with CKD more frequently had a high stroke risk (94.9% vs. 67.0%, p < 0.001) and higher NOAC usage rate (61.1% vs. 47.8%, p < 0.001). Among 718 patients with renal indication for dose reduction (RIDR), 7.5% were potentially overdosed. Among 2587 patients with no-RIDR, 79% were potentially underdosed. Compared with patients with no-RIDR, the underdose rates of dabigatran (0% vs. 88.6%, p = 0.001) and rivaroxaban (0% vs. 79.5%, p = 0.001) were lower in patients with RIDR. However, the underdose rate of apixaban was not different (62.5% vs. 53.9%, p = 0.089). The overdose rate of dabigatran (7.5% vs. 0%) and rivaroxaban (13.7% vs. 0%) was higher in RIDR than in no-RIDR patients. Stroke/transient ischemic attack was significantly higher in CKD patients (1.4 vs. 0.6 per 100 person-years, p = 0.045). Aspirin significantly increased minor bleeding in CKD patients compared with controls (p = 0.037).
Conclusion
CKD patients might have a high stroke risk and NOAC usage rate. The underdose rate of NOACs decreased in CKD patients, except for apixaban. Aspirin significantly increased minor bleeding in CKD patients.

Soluble ST2 is a Useful Biomarker for Grading Cerebral-Cardiac Syndrome in Patients after Acute Ischemic Stroke. J Clin Med 2020; 9:jcm9020489.

Abstract
This study tested whether the soluble (s)ST2 is a superb biomarker predictive of moderate to severe cerebral-cardiac syndrome (CCS) (defined as coexisting National Institute of Health Stroke Scale (NIHSS) >8 and left-ventricular ejection fraction (LVEF) <60%) in patients after acute ischemic stroke (IS). Between November 2015 and October 2017, a total of 99 IS patients were prospectively enrolled and categorized into three groups based on NIHSS, i.e., group 1 (NIHSS ≤ 8, n = 66), group 2 (NIHSS = 9-15, n = 14) and group 3 (NIHSS ≥ 16, n = 19), respectively. Blood samples were collected immediately after hospitalization, followed by transthoracic echocardiographic examination. The results showed that the flow cytometric analysis for assessment of inflammatory biomarkers of TLR2+/CD14+cells, TLR4+/CD14+cells, Ly6g+/CD14+cells, and MPO+/CD14+cells, and ELISA assessment for circulatory level of sST2 were significantly higher in groups 2/3 than in group 1 (all p < 0.01). However, these parameters did not show significant differences between groups 2 and 3 (all p > 0.05). The LVEF was significantly lower in group 3 than in group 1 (p < 0.001), but it displayed no difference between groups 1/2 or between groups 2/3. These inflammatory biomarkers ((TLR2+/CD14+cells// TLR4+/CD14+cells// MPO+/CD14+cells) and sST2)) were significantly positively correlated to NIHSS and strongly negatively correlated to LVEF (all p < 0.05). Multivariate analysis demonstrated that both MPO/CD14+cells >20% (p = 0.027) and sST2 ≥ 17,600 (p = 0.004) were significantly and independently predictive of moderate-severe CCS after acute IS. Receiver operating characteristic curve analysis demonstrated that sST2 was the most powerful predictor of CCS with a sensitivity of 0.929 and a specificity of 0.731 (p < 0.001). In conclusion, sST2 is a useful biomarker for prediction of CCS severity in patients after acute IS.

Abstract
AIMS Worldwide observational studies are evidencing discordance between guidelines and real-world practice regarding direct oral anticoagulant drug (DOAC) doses. This systematic review summarizes and evaluate DOACs use in real-world practice. METHODS This review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines searching PubMed (MEDLINE) and Medscape databases. RESULTS Data from 75 studies showed that most of the patients treated with DOACs for stroke prevention in atrial fibrillation received doses in accordance to the guidelines. However, a significant number of patients received off-label doses (25-50% in most of the studies evaluated). DOAC overdosing was associated with increased all-cause mortality and worse bleeding events while underdosing was associated with increased cardiovascular hospitalization and, particularly for apixaban, with a nearly 5-fold increased risk of stroke. CONCLUSION Patients prescribed with off-label DOAC doses did not receive the full benefit of anticoagulation and presented an increased risk of stroke, bleeding and/or adverse effects.

Abstract
Ibrutinib is the first clinically approved inhibitor of Bruton's tyrosine kinase, an enzyme that is essential for survival and proliferation of B‑cells by activating the B‑cell receptor signalling pathway. Ibrutinib has been shown to be highly effective in B‑cell malignancies in clinical trials and is recommended in current international guidelines as a first and/or second line treatment of chronic lymphocytic leukemia. The drug has a favorable tolerability and safety profile but the occurrence of specific side effects (e.g. atrial fibrillation, bleeding and hypertension) may complicate or be of concern for doctors and patients considering the use of this treatment. In many cases, however, it is not necessary to withhold this effective therapy. In contrast, ibrutinib treatment can be initiated or continued, if certain recommendations are followed. The possibilities of prevention, diagnosis and management of specific clinical situations are discussed in detail and recommendations are derived, which should facilitate ibrutinib use.

Abstract
Drug-induced liver injury (DILI), herbal-induced liver injury, and herbal and dietary supplement (HDS)-induced liver injury are an important aspect of drug safety. Knowledge regarding responsible drugs, mechanisms, risk factors, and the diagnostic tools to detect liver injury have continued to grow in the past year. This review highlights what we considered the most significant publications from among more than 1800 articles relating to liver injury from medications, herbal products, and dietary supplements in 2017 and 2018. The US Drug-Induced Liver Injury Network (DILIN) prospective study highlighted several areas of ongoing study, including the potential utility of human leukocyte antigens and microRNAs as DILI risk factors and new data on racial differences, the role of alcohol consumption, factors associated with prognosis, and updates on the clinical signatures of autoimmune DILI, thiopurines, and HDS agents. Novel data were also generated from the Spanish and Latin American DILI registries as well as from Chinese and Korean case series. A few new agents causing DILI were added to the growing list in the past 2 years, including sodium-glucose co-transporter-2 inhibitors, as were new aspects of chemotherapy-associated liver injury. A number of cases reported previously described hepatotoxins confirmed via the Roussel Uclaf Causality Assessment Method (RUCAM; e.g., norethisterone, methylprednisolone, glatiramer acetate) and/or the DILIN method (e.g., celecoxib, dimethyl fumarate). Additionally, much work centered on elucidating the pathophysiology of DILI, including the importance of bile salt export pumps and immune-mediated mechanisms. Finally, it must be noted that, while hundreds of new studies described DILI in 2017-2018, the quality of such reports must always be addressed. Björnsson reminds us to remain very critical of the data when addressing the future utility of a study, which is why it is so important to adhere to a standardized method such as RUCAM when determining DILI causality. While drug-induced hepatotoxicity remains a diagnosis of exclusion, the diverse array of publications that appeared in 2017 and 2018 provided important advances in our understanding of DILI, paving the way for our improved ability to make a more definitive diagnosis and risk assessment.

Abstract
BACKGROUND Idarucizumab is a monoclonal antibody fragment with high affinity for dabigatran reversing its anticoagulant effects within minutes. Thereby, patients with acute ischemic stroke who are on dabigatran treatment may become eligible for thrombolysis with recombinant tissue-type plasminogen activator (rt-PA). In patients on dabigatran with intracerebral hemorrhage idarucizumab could prevent lesion growth. AIMS To provide insights into the clinical use of idarucizumab in patients under effective dabigatran anticoagulation presenting with signs of acute ischemic stroke or intracranial hemorrhage. METHODS Retrospective data collected from German neurological/neurosurgical departments administering idarucizumab following product launch from January 2016 to August 2018 were used. RESULTS One-hundred and twenty stroke patients received idarucizumab in 61 stroke centers. Eighty patients treated with dabigatran presented with ischemic stroke and 40 patients suffered intracranial bleeding (intracerebral hemorrhage (ICH) in n = 27). In patients receiving intravenous thrombolysis with rt-PA following idarucizumab, 78% showed a median improvement of 7 points in National Institutes of Health Stroke Scale. No bleeding complications were reported. Hematoma growth was observed in 3 out of 27 patients with ICH. Outcome was favorable with a median National Institutes of Health Stroke Scale improvement of 4 points and modified Rankin score 0-3 in 61%. Six out of 40 individuals (15%) with intracranial bleeding died during hospital stay. CONCLUSION Administration of rt-PA after reversal of dabigatran activity with idarucizumab in case of acute ischemic stroke seems feasible, effective, and safe. In dabigatran-associated intracranial hemorrhage, idarucizumab appears to prevent hematoma growth and to improve outcome.

Abstract
The classical oral anticoagulants are increasingly being replaced in clinical practice by new antithrombotic drugs, which act by enabling direct inhibition of coagulation factor IIa (FIIa) or factor Xa (FXa). These drugs have multiple acronyms, including NOACs (new, non-vitamin K antagonist) or DOACs (direct oral anticoagulants), and currently include dabigatran (FIIa inhibitor), and rivaroxaban, apixaban, and edoxaban (FXa inhibitors). These drugs are approved for stroke prevention in patients with non-valvular atrial fibrillation and the prevention and treatment of venous thromboembolism. The "mantra" that DOACs do not require laboratory monitoring is not entirely correct because laboratory testing for drug effects is needed in many situations, because they influence hemostasis tests and in situations in which urgent measurement of DOACs is required. This should be very important to consider in the clinical situation for numbers of indications and increasing numbers of patients on DOACs therapy. The main aim of this article is to provide practical issues to general laboratory testing for DOACs, as well as to help avoid diagnostic errors associated with hemostasis testing. The assays for DOAC quantification must be available in medical centers on a whole day basis, to facilitate optimal drug management in conditions when things go wrong or in urgent cases of immediate reversal of anticoagulation or appropriate administration of a specific antidote.

Abstract
INTRODUCTION The management of patients with a hip fracture is affected by the use of oral anticoagulants. A cross-sectional analysis was undertaken to investigate health outcome differences in those anticoagulated compared to those not anticoagulated. METHODS Patients aged 50 years and over presenting to a large university hospital with hip fractures were identified from the service registry. Patient characteristics and health outcomes between those not anticoagulated were compared with those anticoagulated (warfarin and direct oral anticoagulants, DOAC). RESULTS 200/2307 (9%) patients were anticoagulated. 84% were on warfarin, and the rest a DOAC. Compared to those anticoagulated, there was a higher prevalence of dementia (25% vs. 18%, p = 0.02) and a lower prevalence of cardiovascular disease (54% vs. 78%, p < 0.01), atrial fibrillation (10% vs. 82%, p < 0.01), and polypharmacy (55% vs. 76%, p < 0.01). Renal function was lower in the anticoagulated group. Time to operation for those not anticoagulated and anticoagulated was a median (IQR) of 25 (15) and 27 (18) hours. There was no difference in blood transfusion and hospital mortality. Postoperative complications were similar except a higher rate of renal failure (14% vs. 19%, p = 0.04) and heart failure (1% vs. 5%, p < 0.01), and a longer length of stay [median (IQR): 14 (10) vs. 16 (12) days] in the anticoagulated group. This was no longer significant after adjustment of confounders. CONCLUSION There was no statistically significant difference in health outcomes between those anticoagulated and those not after adjusting for patient characteristics. It was feasible to avoid significant delay in hip fracture surgery in those anticoagulated.

Abstract
Patients on warfarin are required to withdraw from treatment for a fixed period (normally 5 days) prior to an invasive procedure. However, the anticoagulant effect of warfarin subsides at different rates among different patients, exposing some to increased risk of either thrombosis or bleeding. In a recent study in patients awaiting surgery, following warfarin cessation the INR declined slower over time in those with two CYP2C9 variant alleles, increasing age, weight and number of comorbidities and that INR decline was faster in those with higher maintenance INR value. Subsequently, we developed an algorithm which predicts INR decline in individual patients after 5 days of warfarin cessation. The current study validated the algorithm. An independent cohort of patients completing a short course of warfarin took part in the study. INR values for subsequent 9 days and CYP2C9 genotype were available. The predicted INR decline (INRday 1–INRday 5) was compared to the observed one (where an INR check on day 5 was unavailable, INR was estimated using a linear approximation model). There was a strong correlation between the decline in INR by day 5 and that predicted from the algorithm for the 117 patients (r = 0.949, p < 0.001). The algorithm was precise, with low degree of bias and variance of the prediction error. The algorithm can accurately predict the INR decline following warfarin cessation in individual adult patients. The use of this easily adoptable algorithm can reduce cancellation or delays of planned surgical procedures.

Abstract
Vitamin K antagonists (eg, warfarin) have been the standard of care for stroke prophylaxis in atrial fibrillation. The direct oral anticoagulants dabigatran (direct thrombin inhibitor) and rivaroxaban, apixaban, and edoxaban (direct factor Xa inhibitors) are as efficacious as and in some instances superior to vitamin K antagonists in the prevention of stroke, systemic embolism, and major bleeding compared with warfarin for nonvalvular atrial fibrillation. Benefits of direct oral anticoagulants include a rapid onset of therapeutic effect, fixed dose-response relationships without the need for routine monitoring, a short half-life, and infrequent need for periprocedural bridging with a parenteral agent. However, direct oral anticoagulants differ in subsets of patients. Critical care and advanced practice nurses must understand these differences, prescribing considerations, drug aherence interventions, drug-drug interactions, and periprocedural management. This article presents an update and review of direct oral antigcoagulants based on the latest national guidelines.

Abstract
Patients with atrial fibrillation (AF) who suffer an acute ischemic stroke are at risk for both hemorrhagic transformation and recurrent ischemic stroke in the acute post-stroke period. Oral anticoagulants are recommended for secondary stroke prevention in patients with AF. The optimal time to initiate anticoagulant therapy after acute ischemic stroke in patients with AF is uncertain. There is concern that early initiation increases the risk of hemorrhagic transformation, whereas delayed initiation leaves the patient at risk for recurrent ischemic stroke. In this article, we provide a review of the risk of hemorrhagic transformation of acute ischemic stroke as well as review the literature and major guidelines addressing the timing of anticoagulation initiation after an acute ischemic stroke in patients with AF. Relevant articles published from 1990 to the present were identified using the PubMed and Embase databases. The majority of available literature is observational data. Large ischemic lesions, cerebral microbleeds, thrombolytic therapy, and other clinical factors may increase the risk of hemorrhagic transformation of an acute ischemic stroke. Parenteral anticoagulation within 48 hours is associated with an increased risk of hemorrhagic transformation and is not recommended. Insufficient data exist to support the safety of routine oral anticoagulant (direct oral anticoagulants or warfarin) initiation within 48 hours of an acute ischemic stroke. Direct oral anticoagulant initiation within 2 days of an acute ischemic stroke is associated with a 5% rate of hemorrhagic transformation. Infarct size and presence of hemorrhage are important factors in identifying the optimal time to initiation and should guide decisions when available. A recommended framework for patient decision making is provided. Randomized controlled trials in this area are needed to identify the optimal timing of anticoagulation initiation, and such trials are under way.

Abstract
Introduction New oral anticoagulants (NOACs) are approved for use in nonvalvular atrial fibrillation (AF). Objectives This study aimed to evaluate the efficacy and safety of NOACs compared with warfarin in AF and valvular heart disease (VHD). Methods We identified randomized controlled trials (RCTs) and post-hoc analyses comparing NOACs and warfarin in AF and VHD, including biological and mechanical heart valves (MHV). Through systematic review and meta-analysis, with the aid of the “Rev Man” program 5.3, the primary effectiveness endpoints were stroke and systemic embolism (SE). The primary safety outcome was major bleeding, and the secondary outcome included intracranial hemorrhage. Data were analyzed using risk ratios (RRs) and 95% confidence intervals (CIs), and heterogeneity was assessed using the I2 statistic. Results Six RCTs were included, involving 13,850 patients with AF and VHD. NOACs significantly reduced the risk of stroke/SE (RR 0.78; 95% CI 0.66–0.91; P = 0.002) and intracranial hemorrhage (RR 0.51; 95% CI 0.33–0.79; P = 0.003) and lowered the risk of major bleeding (RR 0.77; 95% CI 0.58–1.02; P = 0.07) compared with warfarin. Conclusions The efficacy and safety of NOACs as thromboprophylaxis for AF and VHD are similar to those of warfarin.

[PMID: 31807265 PMCID: PMC6880028 DOI: 10.1177/2042098619888133] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Accepted: 10/18/2019] [Indexed: 12/02/2022] Open
Abstract
Background: Review of clinical data on andexanet alfa for the reversal of factor Xa (FXa)
inhibitor associated anticoagulation. Data sources: In the present review, we identified articles via PubMed
using the combined keywords andexanet alfa, apixaban, enoxaparin, edoxaban,
and rivaroxaban. Additional online searches via PubMed,
Google Scholar, and Lexicomp were conducted for both prescribing and cost
information. Portola Pharmaceuticals was contacted for information used for
United States Food and Drug Administration approval of andexanet alfa. Study selection and data extraction: English-language clinical trials and reviews published between January 2008
and April 2019 were included for review. Bibliographies of selected articles
were reviewed manually for relevant publications, focusing on reversal
strategies for apixaban, enoxaparin, edoxaban, or rivaroxaban associated
anticoagulation using andexanet alfa. Review articles were excluded. Data synthesis: The safety and tolerability of andexanet alfa were evaluated in one phase I,
two phase II, and one phase III clinical trials. The use of andexanet alfa
for reversing FXa inhibitor-associated anticoagulation were evaluated in the
phase III ANNEXA-4 study. Conclusions: Studies evaluating laboratory parameters for coagulation show that andexanet
alfa rapidly neutralizes the anticoagulant effects of apixaban, enoxaparin,
edoxaban, and rivaroxaban. Clinical studies show that andexanet alfa
improves markers related to coagulation, and reverses major bleeding in
healthy volunteers and patients with life-threatening bleeding. Interruption
of anticoagulation may result in thromboembolic and ischemic events. The use
of andexanet alfa requires close monitoring for signs and symptoms of
thromboembolic events, ischemic events, and cardiac arrest. Furthermore,
anticoagulation should be resumed following the administration of andexanet
alfa as soon as medically appropriate.

Abstract
The current manuscript is the second update of the original Practical Guide, published in 2013 [Heidbuchel et al. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace 2013;15:625-651; Heidbuchel et al. Updated European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist anticoagulants in patients with non-valvular atrial fibrillation. Europace 2015;17:1467-1507]. Non-vitamin K antagonist oral anticoagulants (NOACs) are an alternative for vitamin K antagonists (VKAs) to prevent stroke in patients with atrial fibrillation (AF) and have emerged as the preferred choice, particularly in patients newly started on anticoagulation. Both physicians and patients are becoming more accustomed to the use of these drugs in clinical practice. However, many unresolved questions on how to optimally use these agents in specific clinical situations remain. The European Heart Rhythm Association (EHRA) set out to coordinate a unified way of informing physicians on the use of the different NOACs. A writing group identified 20 topics of concrete clinical scenarios for which practical answers were formulated, based on available evidence. The 20 topics are as follows i.e., (1) Eligibility for NOACs; (2) Practical start-up and follow-up scheme for patients on NOACs; (3) Ensuring adherence to prescribed oral anticoagulant intake; (4) Switching between anticoagulant regimens; (5) Pharmacokinetics and drug-drug interactions of NOACs; (6) NOACs in patients with chronic kidney or advanced liver disease; (7) How to measure the anticoagulant effect of NOACs; (8) NOAC plasma level measurement: rare indications, precautions, and potential pitfalls; (9) How to deal with dosing errors; (10) What to do if there is a (suspected) overdose without bleeding, or a clotting test is indicating a potential risk of bleeding; (11) Management of bleeding under NOAC therapy; (12) Patients undergoing a planned invasive procedure, surgery or ablation; (13) Patients requiring an urgent surgical intervention; (14) Patients with AF and coronary artery disease; (15) Avoiding confusion with NOAC dosing across indications; (16) Cardioversion in a NOAC-treated patient; (17) AF patients presenting with acute stroke while on NOACs; (18) NOACs in special situations; (19) Anticoagulation in AF patients with a malignancy; and (20) Optimizing dose adjustments of VKA. Additional information and downloads of the text and anticoagulation cards in different languages can be found on an EHRA website (www.NOACforAF.eu).

Abstract
OBJECTIVES This prospective, comparative, clinical study analyzed the postoperative bleeding risk of patients on anticoagulation therapy (AT) who were undergoing tooth extractions and osteotomies. MATERIALS AND METHODS Patients with the following ATs were included (test groups): (1.) platelet aggregation inhibitors (PAIs), (2.) vitamin K inhibitors, (3.) low molecular weight heparin (LMWH), and (4.) direct oral anticoagulants (DOACs). Patients in the control group were not on any AT (non-AT group). Patients were subdivided into the following treatment groups: (1.) single tooth extraction, (2.) serial extraction (≥ 2 adjacent teeth), and (3.) tooth osteotomy. Pre-, intra-, and postoperative data concerning the treatment, extent of the surgery, and bleeding were recorded and statistically evaluated. RESULTS There were 15 postoperative bleeding events in 838 patients (1.7%): four (0.7%) in the non-AT group (n = 603 patients) and 11 (4.7%) in the AT group (n = 235 patients). The surgical procedure had no statistically significant effect on postoperative bleeding frequencies. Patients taking vitamin K inhibitors had a significantly higher risk of postoperative bleeding compared with patients without AT (p < 0.00001). Four patients were hospitalized due to the severity of the bleeding (vitamin K inhibitor group). Postoperative bleeding events were all controlled with local hemostatic measures. CONCLUSIONS The postoperative bleeding risk after tooth extractions and osteotomies in patients continuing AT is low, and bleeding can be controlled with local hemostatic measures. CLINICAL RELEVANCE AT should be continued in patients undergoing tooth removal procedures under the provision that local hemostatic measures are applied.

Abstract
The advances in the left atrial appendage closure as a stroke prevention method in patients with atrial fibrillation and contraindications to oral anticoagulants made a huge revolution offering a great alternative for patients with a high risk of bleeding. The nitinol-based, self-expanding LAmbre closure system shows promising initial results in terms of efficacy and safety in worldwide different clinical trials offering an alternative to the known Amulet and Watchman closure systems. Lifetech received CE Mark approval for the LAmbre closure system on 15 June 2016. Different studies have shown encouraging results in terms of feasibility and efficacy of the novel occluder. The favorable device design gives a big advantage in the occlusion of difficult left atrial appendage anatomy.

Abstract
Background During treatment with direct oral anticoagulants (DOAC), coagulation assessment is required before thrombolysis, surgery, and if anticoagulation reversal is evaluated. Limited data support the accuracy of DOAC‐specific coagulation assays around the current safe‐for‐treatment threshold of 30 ng/mL. Methods and Results In 481 samples obtained from 96 patients enrolled at a single center, DOAC concentrations were measured using Hemoclot direct thrombin inhibitor assay, Biophen direct thrombin inhibitor assay or ecarin clotting time for dabigatran, chromogenic anti‐Xa assay (AXA) for factor Xa inhibitors (rivaroxaban, apixaban) and ultraperformance liquid chromatography–tandem mass spectrometry as reference. All dabigatran‐specific assays had high sensitivity to concentrations >30 ng/mL, but specificity was lower for Hemoclot direct thrombin inhibitor assay (78.2%) than for Biophen direct thrombin inhibitor assay (98.9%) and ecarin clotting time (94.6%). AXA provided high sensitivity and specificity for rivaroxaban, but low sensitivity for apixaban (73.8%; concentrations up to 82 ng/mL were misclassified as <30 ng/mL). If no DOAC‐specific calibration for AXA is available, results 2‐fold above the upper limit of normal indicate relevant rivaroxaban concentrations. For apixaban, all elevated results should raise suspicion of relevant anticoagulation. Conclusions DOAC‐specific tests differ considerably in diagnostic performance for concentrations close to the currently accepted safe‐for‐treatment threshold. Compared with Biophen direct thrombin inhibitor assay and ecarin clotting time, limited specificity of Hemoclot direct thrombin inhibitor assay poses a high risk of unnecessary anticoagulation reversal or treatment delays in patients on dabigatran. While AXA accurately detected rivaroxaban, the impact of low apixaban levels on the assay was weak. Hence, AXA results need to be interpreted with extreme caution when used to assess hemostatic function in patients on apixaban. Clinical Trial Registration URL: https://www.clinicaltrials.gov.

Abstract
BACKGROUND A novel approach to determine the effect of a treatment is to calculate the delay of event, which estimates the gain of event-free time. The aim of this study was to estimate gains in event-free time for stroke or systemic embolism, death, bleeding events, and the composite of these events, in patients with atrial fibrillation randomized to either warfarin or apixaban in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial (ARISTOTLE). DESIGN The ARISTOTLE study was a randomized double-blind trial comparing apixaban with warfarin. METHODS Laplace regression was used to estimate the delay in time to the outcomes between the apixaban and the warfarin group in 6, 12, 18 and 22 months of follow-up. RESULTS The gain in event-free time for apixaban versus warfarin was 181 (95% confidence interval 76 to 287) days for stroke or systemic embolism and 55 (-4 to 114) days for death after 22 months of follow-up. The corresponding gains in event-free times for major and intracranial bleeding were 206 (130 to 281) and 392 (249 to 535) days, respectively. The overall gain for the composite of all these events was a gain of 116 (60 to 171) days. CONCLUSIONS In patients with atrial fibrillation, 22 months of treatment with apixaban, as compared with warfarin, provided gains of approximately 6 months in event-free time for stroke or systemic embolism, 7 months for major bleeding and 13 months for intracranial bleeding.

Severe Enoral Bleeding with a Direct Oral Anticoagulant after Tooth Extraction and Heparin Bridging Treatment. Case Rep Emerg Med 2019; 2019:6208604.

Abstract
Background The number of patients receiving direct oral anticoagulants (DOACs) is increasing, however, this treatment is associated with the risk of bleeding. More than 10 percent of patients on DOACs have to interrupt their anticoagulation for an invasive procedure every year. For this reason, the correct management of DOACs in the perioperative setting is mandatory. Case Presentation An 81-year-old male patient, with known impaired renal function, presented to our emergency department with a severe enoral bleeding after tooth extraction. The DOAC therapy—indicated by known atrial fibrillation—was interrupted perioperatively and bridged with Low Molecular Weight Heparin (LMWH). The acute bleeding was stopped by local surgery. The factors contributing to the bleeding complication were bridging of DOAC treatment, together with prolonged drug action in chronic kidney disease. Conclusion In order to decide whether it is necessary to stop DOAC medication for tooth extraction, it is important to carefully weigh up the individual risks of bleeding and thrombosis. If DOAC therapy is interrupted, bridging should be reserved for thromboembolic high-risk situations. Particular caution is required in patients with impaired kidney function, due to the risk of accumulation and prolonged anticoagulant effect of both DOACs and LMWH.

Abstract
Bleeding after dental extraction in patients treated with non-vitamin K oral anticoagulants (NOAC) may lead to unplanned reinterventions and interruption of anticoagulation, thereby exposing patients to a risk of thromboembolism. We have designed a study (EXTRACT-NOAC) to investigate whether tranexamic acid (TXA) mouthwash decreases bleeding after extraction in such patients. The study is a randomised, double-blind, placebo-controlled trial. We plan to randomise 236 patients listed for dental extraction and treated with NOAC to 10% TXA mouthwash or placebo. Patients are instructed to use the mouthwash before the dental extraction, and three times a day for three days thereafter. The primary outcome is oral bleeding. Secondary outcomes include type of bleeding, procedural bleeding score, number of reinterventions after oral bleeding, and number of interruptions in NOAC treatment. Any bleeding from sources other than the mouth, and thrombotic events, are recorded as safety outcomes. Patients are followed-up for seven days. This study will provide evidence to guide the management of patients taking NOAC who need teeth extracted.

Abstract
According to the World Health Organization (WHO), more than 36 million people die annually from non-communicable diseases (NCDs), representing over 60% of deaths worldwide, 15 million of which occur before the age of 70 years. Prevention and control of NCDs and their risk factors require interventions that are therapeutically cost-effective, affordable by the patient and/or health systems and feasible, based upon local resources. This commentary paper sets a basis of global evidence to advocate, nationally and internationally, for an expanded role for pharmacists in NCD management by compiling best practices and examples. It encourages pharmacists around the world to act upon NCDs, from prevention and screening activities, to patient referral when appropriate, and to pharmacist-led, patient-centred NCD management to improve outcomes and quality of life. Priority NCDs fall into four areas: cardiovascular diseases, diabetes, asthma/chronic obstructive pulmonary disease and cancer. Building on the key roles they already play as primary healthcare professionals in the community, pharmacists can provide focused interventions, specialised counselling and care coordination, improving patient engagement to achieve better outcomes in the global fight against NCDs.

Abstract
Objectives 1) To evaluate anticoagulation treatment patterns and health care resource use in adult patients with a discharge diagnosis of non-valvular atrial fibrillation (NVAF) in an Italian real-world setting and 2) to describe the characteristics of NVAF patients in relation to treatment. Design A retrospective cohort study in a "real-world" setting. Setting Data were analysed by integrating administrative databases that included approximately 2,000,000 individuals assisted by the National Health System from two Italian Local Health Units. Participants All adult patients with at least one hospital discharge or ≥2 outpatient visits with a diagnosis code for NVAF from 1/01/2011 to 31/12/2015 were included. Main outcome measures Anticoagulation treatment patterns, health care resource use and major bleeding events that occurred during the follow-up period were evaluated. Results 32,863 NVAF patients were included, of whom 7,831 had at least one prescription of oral anticoagulants. Among them, 6,876 patients were vitamin K antagonists (VKA) users and 955 were non-vitamin K antagonist oral anticoagulant (NOAC) users at index date (ID). During the follow-up period, the use of antiplatelet drugs was higher among VKA-naïve users than the NOAC-naïve users. Among NOAC users, 76.1% showed an adherence level ≥80% during follow-up. The rate of bleeding events resulted higher for VKA patients compared to NOAC patients. The unadjusted incidence rate was 10.46 per 1000 person-year for VKA patients and 4.55 per 1,000 person-years for NOAC patients. The overall annual cost (in term of drugs, hospitalisations and outpatient specialist services) was € 5,156.13 for VKA and € 4,630.57 for NOAC. Conclusion This unselected cohort study, on NVAF patients being prescribed oral anticoagulants, highlights that VKA was largely prescribed and the great majority of patients on NOACs were adherent to treatment. Most of the OAC patients still received antiplatelet agents in combination, and in NOAC patients, we registered a lower number of bleeding events compared with VKA.

Consensus Report on Patient Blood Management in Cardiac Surgery by Turkish Society of Cardiovascular Surgery (TSCVS), Turkish Society of Cardiology (TSC), and Society of Cardio-Vascular-Thoracic Anaesthesia and Intensive Care (SCTAIC). TURK GOGUS KALP DAMAR CERRAHISI DERGISI 2019; 27:429-450. [PMID: 32082905 PMCID: PMC7018143 DOI: 10.5606/tgkdc.dergisi.2019.01902] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Accepted: 10/10/2019] [Indexed: 01/18/2023]
Abstract
Anemia, transfusion and bleeding independently increase the risk of complications and mortality in cardiac surgery. The main goals of patient blood management are to treat anemia, prevent bleeding, and optimize the use of blood products during the perioperative period. The benefit of this program has been confirmed in many studies and its utilization is strongly recommended by professional organizations. This consensus report has been prepared by the authors who are the task members appointed by the Turkish Society of Cardiovascular Surgery, Turkish Society of Cardiology (TSC), and Society of Cardio-Vascular-Thoracic Anaesthesia and Intensive Care to raise the awareness of patient blood management. This report aims to summarize recommendations for all perioperative blood- conserving strategies in cardiac surgery.

Abstract
Importance Non-vitamin K oral anticoagulants (NOACs) are increasingly prescribed for patients to treat or prevent arterial or venous thromboembolism. The following 4 NOAC agents are approved by the US Food and Drug Administration for clinical use: dabigatran etexilate, apixaban, edoxaban tosylate, and rivaroxaban. A good understanding of these agents' pharmacologic properties is important for surgeons given their marked differences compared with warfarin sodium. This review highlights key practical issues surrounding the use of NOACs in the perioperative setting. Observations The PubMed and Cochrane Library databases were searched for English-language studies from May 1, 2009, until May 1, 2017, for randomized clinical trials, meta-analyses, systematic reviews, observational studies, and clinical guidelines. From a systematic review of the published literature that included 70 articles and 166 404 patients, this study identified 5 key practical issues surrounding the use of NOACs in the perioperative setting. These include patient populations for which NOAC use is indicated and contraindicated, the timing of NOAC treatment cessation before invasive interventions, management of NOAC-treated patients requiring urgent interventions, the need for "bridging," and the timing of NOAC treatment's reinitiation after invasive interventions. Important findings are as follows: NOAC agents are not recommended for patients with mechanical heart valves or advanced kidney disease (creatinine clearance, <15 mL/min); minimal to no anticoagulant effect remains when therapy with a NOAC is withheld for 48 to 72 hours before surgery in the context of normal kidney function; a reversal agent is clinically available for dabigatran, while reversal agents for apixaban, edoxaban, and rivaroxaban are under regulatory review; and laboratory testing of the anticoagulant effects of NOACs are not routinely available. There is a paucity of high-quality data on the optimal timing of NOAC cessation and resumption in the perioperative period, particularly for patients who undergo procedures with high bleeding risk. Conclusions and Relevance The anticoagulant effect of NOAC agents is predictable but not readily measurable in routine clinical practice. A number of uncertainties remain surrounding the use of these agents in the perioperative setting. Ongoing prospective studies and randomized clinical trials will provide greater clarity on these management issues in the near future.

Nephrol Dial Transplant 2019; 33:1304-1309. [PMID: 28992319 DOI: 10.1093/ndt/gfx265] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2017] [Accepted: 07/15/2017] [Indexed: 01/06/2023] Open
Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia of high clinical importance, occurring in 2% of the general population and in 19-24% in patients with chronic kidney disease. It is a well-known risk factor for cardiovascular morbidity and mortality. Kidney transplant recipients with a history of AF were associated with significantly higher rate of ischaemic strokes, graft failure and post-transplant mortality. AF occurs in over 7% of kidney transplant recipients in the first 3 years after transplantation and is associated with reduced graft and patient survival. The incidence of stroke in patients after kidney transplantation (KTx) is higher than the general population, but markedly lower than those on dialysis. Oral anticoagulation (OAC) therapy is recommended in AF patients at high risk of stroke. There are no randomized studies assessing OAC in patients after KTx and there are no specific recommendations and guidelines on therapeutic strategies in these patients. KTx recipients are a vulnerable population, exposed to variations in renal function, being at higher risk of bleeding and thrombotic complications, with possible interactions with immunosuppression. Surely, there is a place for novel oral anticoagulants (NOACs) in this group of patients as long as the summary of product characteristics is followed, as they are a valuable anticoagulation therapy. On one hand, they are at least as effective as warfarin; on the other hand NOACs are safer, especially when it comes to intracranial haemorrhages. However, NOACs seem to be underused in this population as they are excreted via kidney, may interact with immunosuppressive therapy and physicians need more experience and confidence in their administration. Percutaneous left atrial appendage occlusion procedure may also be considered as an opportunity for this group of patients, in particular in the presence of contraindications to anticoagulation.
