Microbleed-only patients shared similar demographic, apolipoprotein E, and vascular risk profiles with lobar ICH patients, but had more lobar microbleeds (median, 10 versus 2; P<0.001) and higher leukoaraiosis volumes (median, 31 versus 23 mL; P=0.02). Microbleed-only patients had a nontrivial incidence rate of ICH, not different from patients presenting with ICH (5 versus 8.9 per 100 person-years; adjusted hazard ratio, 0.58; 95% confidence interval, 0.31-1.06; P=0.08). Microbleed-only patients had a higher mortality rate (hazard ratio, 1.67; 95% confidence interval, 1.1-2.6) compared with ICH survivors. Warfarin use and increasing age were independent predictors of future ICH among microbleed-only patients after correction for other covariates.

Aspirin is not associated with a risk of ICH compared with no therapy. Chronic low-dose aspirin treatment may have a protective effect on the risk of SAH. Warfarin users in this study cohort were at a much higher risk of ICH than those receiving no therapy, with a marked association with international normalized ratio >3.

Although a lower target prothrombin time-international normalized ratio (PT-INR) with warfarin therapy is recommended in Japan for atrial fibrillation (AF) patients ≥70 years of age, few studies have provided supporting data. The current study aimed to evaluate the clinical outcome in elderly Japanese patients with non-valvular AF who were taking warfarin.

Computerized alert and reminder systems have been widely accepted and applied to various patient care settings, with increasing numbers of clinical laboratories communicating critical laboratory test values to professionals via either manual notification or automated alerting systems/computerized reminders. Warfarin, an oral anticoagulant, exhibits narrow therapeutic range between treatment response and adverse events. It requires close monitoring of prothrombin time (PT)/international normalized ratio (INR) to ensure patient safety. This study was aimed to evaluate clinical outcomes of patients on warfarin therapy following implementation of a Personal Handy-phone System-based (PHS) alert system capable of generating and delivering text messages to communicate critical PT/INR laboratory results to practitioners' mobile phones in a large tertiary teaching hospital.

Ten cohort studies were included, including a total of 1,501 patients receiving dabigatran and 2,356 receiving warfarin. The mean age was 59-64 years and inclusion of women varied (10-33 %). Intra-procedural unfractionated heparin and irrigated ablation catheters were used routinely. Adverse events were low overall; however, the dabigatran group demonstrated a numerical excess of neurological events (10/1,501 [0.7 %] versus 4/2,356 [0.2 %]), but equivalent major bleeding outcomes (24/1,501 [1.6 %] versus 40/2,356 [1.7 %]). In the meta-analysis, there was a nonsignificant trend towards higher rates of the composite primary endpoints (any neurological event or major bleeding) in the dabigatran group. Dabigatran demonstrated a significantly higher rate of neurological events (estimated absolute risk difference 0.0047, 95 % confidence interval 0.0007 to 0.0099).

Hypercoagulable states (HS) are inherited or acquired conditions that predispose an individual to venous and/or arterial thrombosis. The dermatologist can play a vital role in diagnosing a patient's HS by recognizing the associated cutaneous manifestations, such as purpura, purpura fulminans, livedo reticularis, livedo vasculopathy (atrophie blanche), anetoderma, chronic venous ulcers, and superficial venous thrombosis. The cutaneous manifestations of HS are generally nonspecific, but identification of an abnormal finding can warrant a further workup for an underlying thrombophilic disorder. This review will focus on the basic science of hemostasis, the evaluation of HS, the skin manifestations associated with hypercoagulability, and the use of antiplatelet and anticoagulant therapy in dermatology.

We describe a 70-year-old Haitian man who had been taking warfarin for 5 years for atrial fibrillation and pulmonary hypertension. This patient had his international normalized ratio (INR) checked in the pharmacist-run anticoagulation clinic and was followed monthly. Prior to the interaction, his INR was therapeutic for 5 months while taking warfarin 10.5 mg/d. The patient presented with an INR > 8.0. Patient held 4 days of warfarin and restarted on warfarin 8.5 mg/d. Two weeks later, his INR was 2.5. After continuing dose, patient presented 2 weeks later and INR was 4.8. Upon further questioning, the patient stated he recently began ingesting mauby. Mauby is a bitter dark liquid extracted from the bark of the mauby tree that is commonly used in the Caribbean population as a folk remedy with many health benefits. This case report illustrates that mauby may have a probable drug-herb interaction (Naranjo Algorithm Score of 6) when given with warfarin. There is a lack of published literature and unclear information on the Internet describing the interaction of mauby and warfarin. Health professionals should be cautious regarding interactions between warfarin and mauby until the interaction is fully elucidated.

As also seen for other newly marketed drugs, differences in baseline characteristics, comedication, and comorbidities were detected between DE and W in newly diagnosed patients, as well as in warfarin-experienced patients. This channeling may have significant impact on comparative outcome studies if not properly addressed in study design and analysis.

The geometric mean ratios (GMRs) (90% confidence interval (CI)) of AUC0-∞ and Cmax for (linagliptin + warfarin)/warfarin were 98.5 (95.7 - 101.5) and 99.7 (94.7 - 104.9), respectively, for R-warfarin; 103.0 (99.1 - 107.0) and 100.9 (93.7 - 108.6), respectively, for S-warfarin. Concomitant administration of linagliptin and warfarin had o clinically relevant effect on the AUC0-168 for INR or PT. The GMRs (90% CI) of INR nd PT AUC0-168 for (linagliptin + warfarin)/ warfarin were 93.4 (86.2 - 101.1) and 103.2 (95.4 - 111.6), respectively. The corresponding Eax values for both INR and PT were slightly increased after co-administration of linagliptin and warfarin compared with warfarin alone, being 104.3 (85.2 - 127.6) and 15.1 (94.3 -140.6), respectively, reflecting the higher variability of these endpoints. Co-administration of linagliptin and warfarin was well tolerated.

NT-proBNP levels are often elevated in AF and independently associated with an increased risk of stroke and mortality. NT-proBNP improves risk stratification beyond the CHA2DS2VASc score and might be a novel tool for improved stroke prediction in AF. The efficacy of apixaban compared with warfarin is independent of the NT-proBNP level. (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation [ARISTOTLE]; NCT00412984).

Until recently, vitamin K antagonists, warfarin being the most commonly used agent in the United States, have been the only oral anticoagulant therapies available to prevent stroke in patients with atrial fibrillation (AF). In the last 5 years four new, non-vitamin K oral anticoagulants, the so-called NOACs or novel oral anticoagulants, have come to market and been approved by the Federal Drug Administration. Despite comparable if not superior efficacy in preventing AF-related stroke, and generally lower risks of major hemorrhage, particularly intracranial bleeding, the uptake of these agents has been slow. A number of barriers stand in the way of the more widespread use of these novel agents. Chief among them is concern about the lack of antidotes or reversal agents. Other concerns include the need for strict medication adherence, since missing even a single dose can lead to a non-anticoagulated state; out-of-pocket costs for patients; the lack of easily available laboratory tests to quantitatively assess the level of anticoagulant activity when these agents are being used; contraindications to use in patients with severe chronic kidney disease; and black-box warnings about the increased risk of thromboembolic events if these agents are discontinued prematurely. Fortunately, a number of reversal agents are in the pipeline. Three reversal agents, idarucizumab, andexanet alfa, and aripazine, have already progressed to human studies and show great promise as either antidotes for specific drugs or as universal reversal agents. The availability of these reversal agents will likely increase the clinical use of the non-vitamin K oral anticoagulants. In light of the many complex and nuanced issues surrounding the choice of an optimal anticoagulant for any AF patient, a patient-centered/shared decision-making approach will be useful.

The optimal management of hematologic malignancy-associated venous thromboembolism (VTE) in patients with moderate-to-severe thrombocytopenia is unclear. This is a retrospective study of 128 adult patients with hematologic malignancies who were diagnosed with VTE. The outcome of patients with significant thrombocytopenia (≤50,000/µL) was compared with those without. Forty-seven patients (36.7%) had a platelet count ≤50,000/µL during a period of time of perceived need for new or continued anticoagulation. The median nadir platelet count in those with significant thrombocytopenia was 10,000/µL (range 2,000-45,000/µL) versus 165,000/µL (50,000-429,000/µL) in those without (P < 0.001). The median duration of significant thrombocytopenia in the first group was 10 days (1-35 days). Therapy during the period of significant thrombocytopenia included prophylactic-dose low-molecular-weight heparin (LMWH) (47%), therapeutic-dose LMWH or heparin (30%), warfarin (2%), inferior vena cava filter (2%), and observation (17%). Patients without thrombocytopenia were managed with the standard of care therapy. At a median follow-up of more than 2 years, the risk of clinically significant bleeding (11% vs 6%, P = 0.22) including major bleeding (6% vs 2%) and clot progression or recurrence (21% vs 22%, P = 1.00) were similar in patients with or without significant thrombocytopenia. In a multivariate analysis, the risk of recurrence/progression (hazard ratio, HR 0.59, 95% CI 0.21-1.66, P = 0.31) and hemorrhage rate (HR 0.29, 95% CI 0.05-1.56, P = 0.15) did not differ based on the presence of significant thrombocytopenia. Within the limits of this retrospective study, cautious use of prophylactic-dose LMWH may be safe in thrombocytopenic patients with hematologic malignancy-associated VTE. Am. J.

Warfarin is an anticoagulant suppressing the synthesis of the specific vitamin K-dependent coagulation factors II, VII, IX and X as well as two vitamin K-dependent plasma proteins C and S. Warfarin therapy may bring about severe consequences including warfarin embryopathy associated with maternal warfarin ingestion, warfarin resistance, excessive anticoagulation and warfarin reversal. A 51-year-old female patient experienced warfarin resistance as well as subsequent excessive coagulation and warfarin reversal. With regulation of warfarin dosage and close monitoring of the international normalized ratio, she eventually obtained a proper target international normalized ratio with stable warfarin dose. The patient was more likely to have an acquired warfarin resistance. To regulate dietary habit might be a good solution for the resistance to this drug. In addition, individualized regimen for warfarin use should be established based on the conditions of individual patient including patient's age, gender, body surface area, dietary habit and target international normalized ratio, etc.
Bleeding-related wound complications cause significant morbidity in lower limb arthroplasty surgery. Patients who require therapeutic anticoagulation in the perioperative period are potentially at higher risk for these complications. This is a retrospective case-control study reviewing all primary total hip arthroplasties performed in a single center during a 5-year period and comparing outcomes of the patients on warfarin with a double-matched control group of patients not on warfarin. The warfarin group had a significantly higher risk of deep joint infection (9% vs 2.2%), hematoma/wound ooze (28% vs 4%), and superficial infection (13.5% vs 2.2%). Managing patients undergoing total hip arthroplasty with therapeutic anticoagulation is a balance between the risk of thromboembolic disease and bleeding-related complications. Improved understanding of this risk will better allow patients to make an informed decision regarding their elective arthroplasty surgery.

This open-label, multi-dose, single-center, sequential, inpatient study evaluated the effects of a two herb combination drug (T89, Danshen plus Sanqi) on the steady-state pharmacodynamics (PD) and pharmacokinetics (PK) of warfarin in 24 healthy volunteers. Twenty-three subjects attained a stable international normalized ratio (INR) by taking warfarin alone prior to 1-week of added-on use of T89. INR was not increased after the addition of T89 for 7 days (P > .05). The 90% confidence interval (CI) of the geometric mean ratio for maximum plasma concentrations (Cmax) and area under curve (AUClast ) of both R- and S-warfarin when warfarin was administered with or without T89 was within the 0.80 to 1.25 equivalence ratio. These results indicate that T89 has no effect on the steady-state PD and PK of warfarin. Warfarin and T89 dose adjustments are not required when these two drugs are co-administrated in clinical practice.

tPA and anticoagulation for treatment of severe frostbite have been reported suggesting differences in imaging techniques, route of tPA administration and management of patients after tPA infusion. This is a report of our results following a protocol of Tc-99m scanning, intravenous tPA administration, followed by either systemic anticoagulation or antiplatelet therapy.
Antithrombotic therapy plays an essential role in the management of some of the most common and morbid medical conditions. Triple oral antithrombotic therapy (TOAT) is defined as the administration of both therapeutic oral anticoagulation (OAC) and dual antiplatelet therapy (DAPT) to patients with indications for both treatments. The current societal guidelines regarding TOAT are derived from observational studies and some trials of the use of warfarin in addition to antiplatelet therapy in patients with atrial fibrillation and a recent acute coronary syndrome or percutaneous coronary intervention. The general apprehension to administer TOAT is due to the heightened concern for bleeding, rendering warfarin's pharmacokinetic properties concerning. Newer anticoagulant agents may serve as appealing alternatives, and further investigations are warranted. The results of the recent trials that have studied the use of these agents in atrial fibrillation and acute coronary syndrome offer some useful applications to TOAT. Ultimately, selecting the most favorable antithrombotic strategy is going to involve weighing the risks and benefits for each patient.
