The therapeutic approach towards thrombosis in Behçet's disease differs significantly among rheumatologists from different countries. The different prevalence of the disease in these countries may explain this difference. A randomised controlled prospective trial is needed in order to determine the exact role of anticoagulant treatment in BD.

Cerebral cavernous malformations (CCMs) are vascular malformations in the brain and spinal cord comprising closely clustered, enlarged capillary channels (caverns) with a single layer of endothelium without mature vessel wall elements or normal intervening brain parenchyma. The diameter of CCMs ranges from a few millimeters to several centimeters. CCMs increase or decrease in size and increase in number over time. Hundreds of lesions may be identified, depending on the person’s age and the quality and type of brain imaging used. Although CCMs have been reported in infants and children, the majority become evident between the second and fifth decades with findings such as seizures, focal neurologic deficits, nonspecific headaches, and cerebral hemorrhage. Up to 50% of individuals with FCCM remain symptom free throughout their lives. Cutaneous vascular lesions are found in 9% of those with familial cerebral cavernous malformations (FCCM; see Diagnosis/testing) and retinal vascular lesions in almost 5%.

Novel oral anticoagulants (NOACs) expanded the options for stroke prevention in atrial fibrillation (AF). Earlier studies comparing their relative effectiveness and safety typically do not incorporate age-related differences or postmarketing studies. This study aimed to summarize and compare clinical and safety outcomes of oral antithrombotics for stroke prevention in AF in younger (65-74 years) and older (≥75 years) elderly.

During 2002 to 2010 we prospectively included 160 patients treated with PCC for emergency reversal of warfarin either for bleeding or because of the need of emergency surgery. A possible relationship to PCC was considered if objectively verified thromboembolism occurred within 7days of PCC administration. Efficacy was adjudicated as good if the bleeding was controlled promptly or if the surgeon did not report excessive perioperative bleeding.

Pharmacokinetic parameters for (R)- and (S)-warfarin were similar to the literature. (R)-warfarin 80 mg alone resulted in a mean AUC(PT) (0,168 h) of 3550 s h (95% CI 3220, 3880). Rac-warfarin sodium 25 mg containing (S)-warfarin 11.7 mg produced a greater effect on AUC(PT) (0,168 h) than (S)-warfarin 12.5 mg (mean difference 250 s.h, 95% CI 110, 380, P < 0.002) given alone. In a mixed effects model the ratio of response between (R)- and (S)-warfarin (AUC(PT((R)-warfarin)) : AUC(PT((S)-warfarin))) was 1.21 fold higher (95% CI 1.05, 1.41, P < 0.02) in subjects of VKORC1 TT genotype compared with the CC genotype.

Warfarin reduces the risk of stroke in patients with atrial fibrillation (AF) but is often underused in clinical practice. We aimed to examine the current state of warfarin use in nonvalvular atrial fibrillation (NVAF) patients with first-ever ischemic stroke (IS) or transient ischemic attack (TIA) in China and to analysis factors causing such underuse.

To better understand the factors that contribute to the accumulation of unmetabolized parabens (p-hydroxybenzoic acid esters) in breast cancer tissue, the binding of a series of parabens (methyl-, ethyl-, butyl-, benzyl-paraben) to human serum albumin (HSA) was investigated by fluorescence spectroscopy and also their ability to modify the binding parameters of albumin site markers. Emission spectra of HSA upon fluorescence excitation of Trp 214 residue at 295 nm were recorded at different molar ratios of PB/HSA and data were corrected for the inner-filter effect. A significant inner-filter effect was obtained for molar ratios of 2.0 and above. For lower molar ratios, a slight increase in fluorescence of HSA was detected. p-Hydroxybenzoic acid, the main metabolite of parabens, did not modify the fluorescence of HSA whatever the molar ratio used. Binding parameters for compounds that are markers of site I, bilirubin and warfarin, were determined in the absence and presence of methyl, butyl and benzyl paraben at molar ratios of PB/HSA of 0, 1 and 2. No variation of the binding constants of these markers was observed. The results indicate that parabens weakly interact with HSA thus suggesting that they are in a free form in blood and therefore more available to reach tissues.

AF prevalence was 15% (AL 9%, m-ATTR 11%, wt-ATTR 40%). During a median follow-up of 1.2 years 11 patients developed AF (2.1% person-years). Age, heart failure (HF), left ventricular (LV) ejection fraction, renal involvement, left atrial size and right atrial pressure were independently associated with AF. AF was associated with incident HF but not with increased mortality. All AF patients were prescribed warfarin and none suffered thromboembolic events.
Patients with atrial fibrillation (AF) who are treated with oral anticoagulants often have concurrent coronary artery disease. Triple oral antithrombotic therapy (TOAT) is often necessity to prevent stent thrombosis or myocardial infarction associated with percutaneous coronary intervention or acute coronary syndrome in patients with comorbid coronary artery disease and AF. Although the use of TOAT (aspirin, clopidogrel, and warfarin) has excellent efficacy against thrombotic complications, this comes on the expense of increased bleeding risk. This review discusses potential strategies to improve TOAT benefit-risk ratio evidence from the literature. These strategies include: (1) dropping aspirin; (2) reducing the duration of TOAT; (3) switching warfarin to a direct oral anticoagulant (DOAC); (4) the use of DOAC in combination with a single antiplatelet agent; and (5) switching clopidogrel to a novel antiplatelet agent. Although dropping aspirin and reducing TOAT duration should be considered in selected AF patients at low risk of thrombosis, the role of DOACs and novel antiplatelets in TOAT has not been thoroughly studied, and there is limited evidence to support their use currently. Ongoing studies will provide safety and efficacy data to guide clinicians who frequently face the challenge of determining the best TOAT combination for their patients.
Despite relatively lower prevalence of atrial fibrillation (AF) in Asians (~1%) than in Caucasians (~2%), Asia has a much higher overall disease burden because of its proportionally larger aged population. For example, on the basis of reported age-adjusted prevalence rates and projected population figures in China, there will be an estimated 5.2 million men and 3.1 million women with AF older than 60 years by year 2050. Stroke is a disabling complication of AF that is of increasing cause for concern in Asians patients. Implementing consensus expert recommendations for managing stroke risk in patients with AF can considerably reduce stroke rates. However, caution is necessary when aligning management of Asian patients with AF to that of their Caucasian counterparts. Current international guidelines and risk stratification tools for AF management are based on findings in predominantly Caucasian populations and may therefore have limited relevance, in certain respects, to Asian patients. Oral anticoagulants play an important role in preventing AF-related stroke. The vitamin K antagonist warfarin is recommended for reducing the risk of stroke and thromboembolism in high-risk patients with nonvalvular AF; however, warfarin interacts with many drugs and food ingredients, which may pose significant challenges in administration and monitoring among Asian patients. Further research is needed to inform specific guidance on the implications of different stroke and bleeding profiles in Asians vs Caucasians. Moreover, there is scope to improve physician perceptions and patient knowledge, as well as considering alternative new oral anticoagulants, for example, direct thrombin inhibitors or factor Xa inhibitors.

Regorafenib and its metabolites may inhibit the activities of several CYP or UDP-glucuronosyltransferase isoforms, including that of CYP2C9. Therefore, pharmacological agents that are CYP2C9 substrates may show elevated circulating levels and enhanced drug efficacy when concurrently used with regorafenib. Previous studies showed that the area under the plasma concentration-time curve of warfarin, which is the substrate for CYP2C9, increased upon co-administration of regorafenib. However, there are no reports indicating that the anticoagulant effects of warfarin increased upon co-administration of regorafenib.
Pulmonary embolism was diagnosed in 983 patients. Among these, 237 were considered ineligible for home treatment because of instability or hypoxia. Home treatment was selected for 13 of 746 (1.7%) patients who were potentially eligible. Anticoagulant treatment for those treated at home was low-molecular-weight heparin or warfarin in 9 (69.2%) and novel oral anticoagulants in 4 (30.8%). Hospitalization was chosen for 733 of 746 (98.3%). Discharge in ≤2 days was in 119 patients (16.2%). Treatment of these patients was low-molecular-weight heparin or warfarin in 76 (63.9%), novel oral anticoagulants in 34 (28.6%), and in 9 (7.6%), anticoagulants were not given because of metastatic cancer or treatment was not known.

A total of 572 (15.3% per year) clinically relevant bleeding and 103 (2.6% per year) major bleeding events occurred. Patients receiving combination antithrombotic therapy had a 2.3- to 2.5-fold increased risk of clinically relevant bleeding events and major bleeding events, respectively, compared with those receiving anticoagulation therapy only. Multivariate analyses (hazard ratio, 95% CI) revealed that the risk of clinically relevant bleeding was significantly increased by age 65 to 74 years (1.44, 1.14-1.82) and ≥ 75 years (1.59, 1.24-2.04, P = .001) and by combination antithrombotic therapy (2.47, 2.07-2.96, P < .0001). The same held true for major bleeding events, with analogous figures for age 65 to 74 years (2.26, 1.08-4.71) and ≥ 75 years (4.19, 1.98-8.87, P = .0004) and for combination antithrombotic therapy (2.23, 1.49-3.34, P < .0001). Combination antithrombotic therapy was not associated with a decrease in ischemic stroke risk compared with anticoagulation therapy only (11 [1.4% per year] vs 22 [0.7% per year]; adjusted hazard ratio, 2.01; 95% CI, 0.94-4.30; P = .07).

Patients with atrial fibrillation (AF) in the acute stage of ischemic stroke or transient ischemic attack (TIA) are at high risk of recurrent stroke, but the optimal anticoagulation strategy remains unclear due to the concern of intracranial bleeding. Novel oral anticoagulants compared to warfarin might be more safe and efficacious in patients suitable for early anticoagulation.

Bleeding gastrointestinal angiodysplasia was demonstrated in 5 out of the 12 (41.6%) patients who underwent endoscopy from the cohort of 66 cfLVAD supported patients (7.6%). The incidence of bleeding angiodysplasia was higher than the age-standardized rate of andiodysplasia from literature (0.8%). Active gastrointestinal bleeding in one other patient was due to diverticulosis. The five patients with bleeding angiodysplasia tended to be older than the remaining 61 patients (58.8 ± 10.3 vs 49.6 ± 15.7 years, p = 0.2).

The current mainstay of the treatment and secondary thromboprophylaxis of thrombotic antiphospholipid syndrome (APS) is anticoagulation with warfarin or other vitamin K antagonists (VKAs). In addition to their well-known limitations, VKAs are often problematic in APS patients because of the variable sensitivity of thromboplastins to lupus anticoagulant. As a result, the international normalized ratio may not accurately reflect the intensity of anticoagulation. Direct oral anticoagulants (DOACs) are established as therapeutic alternatives to VKAs for a wide range of indications, including the treatment and secondary prevention of venous thromboembolism. Definition of the role of DOACs in the treatment of thrombotic APS is emerging with the results of recent and ongoing clinical studies. This review focuses on the current situation with regard to DOACs for secondary thromboprophylaxis in APS and issues pertinent to DOAC use in APS patients, as well as potential future directions.

In Japan, powders for reconstitution are often dispensed in sachets, and parents add small amount of water or syrups to make the powders paste-like or condensed syrup and have their children take the medicines. Compounding is common just like any other parts of the world. According to the survey in 2005, most commonly compounded medicines include warfarin, digoxin and enalapril. Crushed tablets or capsules are often mixed with sucrose or starch and kept in bottles at pharmacy departments for regular use. There is no regulation so far to mandate pediatric drug/formulation development in Japan. The pediatric premium can be given to drugs whose indications and dosage are clearly for children, but this is not sufficient for many drug companies especially when their drug prices are cheap. In 2013, new MHLW grant-supported project for regulatory science in pediatric drug development started, and discussion on key issues related to pediatric drug development including formulations, modeling and simulation and neonatal drug evaluation is ongoing including the possible change on legal framework to facilitate pediatric drug development in the country. Initiation of international collaboration with global partners including the European Paediatric Formulation Initiative is to be expected.

A 28-year-old, hypertensive and hypercholesterolaemic patient, was referred to our emergency unit with a mild thoracic pain, productive cough and a body temperature of 37.3°C. Laboratory examinations showed normal white cell count and moderate elevation of C reactive protein (CRP). Later, the thoracic pain increased accompanied by shortness of breath. High D-dimer was detected. Positive lupic anticoagulant factor and anticardiolipin and antibodies anti-Mycoplasma pneumoniae were present and high titres of antinuclear factor. Recombinant tissue-type plasminogen activator plus heparin and vancomycin were administered due the high possibility of mycoplasma pneumonia associated with pulmonary thromboembolism. CRP increased to very high levels with very mild modification of white blood cells during the evolution. Thoracic tomography and pulmonary scintigraphy of the lungs confirmed the diagnosis. The patient responded well and he was discharged after 25 days medicated with hydroxychloroquine sulphate, warfarin and aspirin. At present date he is well (150 days).

A simple and rapid liquid chromatographic-tandem mass spectrometric method has been developed and validated for the enantiospecific determination of R- and S-warfarin in human urine. Warfarin enantiomers were extracted from urine using methyl tert-butyl ether. Chromatographic separation of warfarin enantiomers and the internal standard d5-warfarin was achieved using a Astec Chirobiotic V column with gradient mobile phase at a flow rate of 400 µL/min over 10 min. Detection was performed on a TSQ Quantum Ultra triple quadrupole mass spectrometer equipped with a heated electrospray ionization source. Analytes were detected in negative ionization mode using selected reaction monitoring. Calibration curves were linear with a correlation coefficient of ≥0.996 for both enantiomers over a concentration range of 5-500 ng/mL. The intra- and interday accuracy and precision for both analytes were within ±9.0%. Excellent extraction efficiency and negligible matrix effects were observed. The applicability of the method was demonstrated by successful measurement of warfarin enantiomers in urine of patients with kidney disease. The method is simple, accurate and reproducible and is currently being used to support warfarin pharmacokinetic studies.
Cerebral sinovenous thrombosis (CSVT) in children has rarely been reported in the literature, especially without underlying disorder. It has increasingly been diagnosed due to clinical awareness and sensitive neuroimaging techniques. The aim of this article was to report a case of cerebral sinovenous thrombosis without underlying disorder. We reported a 5 year old girl, presented with severe headache and seizure. She had a history of fever and diarrhea before the onset of headache. Neuroimaging showed evidence of CSVT on MRI and magnetic resonance venography. Investigations showed no inherited thrombophilia. The patient was treated with low molecular weight heparin (LMWH) which continued by warfarin. This case illustrated severe complications of dehydration in pediatrics without any evidence of underlying disorders.
