Patients who took warfarin without PPI co-therapy had 119 hospitalizations for upper gastrointestinal bleeding per 10,000 person-years of treatment. The risk decreased by 24% among patients who received PPI co-therapy (adjusted hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.63-0.91). There was no significant reduction in the risk of other gastrointestinal bleeding hospitalizations (HR, 1.07; 95% CI, 0.94-1.22) or non-gastrointestinal bleeding hospitalizations (HR, 0.98; 95% CI, 0.84-1.15) in this group. Among patients concurrently using antiplatelet drugs or NSAIDs, those without PPI co-therapy had 284 upper gastrointestinal bleeding hospitalizations per 10,000 person-years of warfarin treatment. The risk decreased by 45% (HR, 0.55; 95% CI, 0.39-0.77) with PPI co-therapy. PPI co-therapy had no significant protective effect for warfarin patients not using antiplatelet drugs or NSAIDs (HR, 0.86; 95% CI, 0.70-1.06). Findings were similar in both study populations.

A retrospective cohort study of 2,218 patients with deep vein thrombosis or pulmonary embolism during a 25-year period from 1966-1990 in Minnesota showed an annual incidence of venous thromboembolism of 117 per 100,000 (deep vein thrombosis, 48 per 100,000; pulmonary embolism, 69 per 100,000). Higher rates were found in males than females (130 vs 110 per 100,000, respectively) after adjusting for age. Early diagnosis and appropriate treatment of DVT and PE have been shown to significantly reduce mortality and morbidity. Risk factors for venous thromboembolism include alterations in blood flow (surgery, injury or long-distance air travel, pregnancy, obesity), hypercoagulability (factor V Leiden mutation, prothrombin mutation, protein C deficiency, protein S deficiency, antithrombin deficiency, hyperhomocysteinemia, antiphospholipid syndrome, nephrotic syndrome, paroxysmal nocturnal hemoglobinuria) and vessel wall abnormalities. Eighty percent of deep venous thrombosis resolves spontaneously and less than 15% embolize to pulmonary arteries.

Blacks were less likely than whites to be aware of having AF or to be treated with warfarin. Potential reasons for the racial disparity in warfarin treatment warrant further investigation.

coumadin overdose treatment

A total of 146 adults who received at least one dose of apixaban (73 patients) or warfarin (73 patients) while hospitalized between January 30, 2014, and December 31, 2015, and had a CrCl of < 25 ml/minute or SCr of > 2.5 mg/dl, or who received peritoneal dialysis or hemodialysis, were included. Patients who were taking warfarin and had a therapeutic international normalized ratio on admission were matched consecutively in a 1:1 fashion in chronologic order to patients taking apixaban based on renal function and indication for anticoagulation.

APT scores were based on 25 key scientific and feasibility criteria relevant for clinical research evaluating the genetic basis of ADRs, with a maximum possible score of 60 points. The tool was independently applied to five ADRs (warfarin-induced bleeding/thrombosis, cisplatin-induced ototoxicity, methotrexate-induced neutropenia, carbamazepine-induced Stevens-Johnson syndrome, and abacavir-induced hypersensitivity) by two researchers. Scores were compared using the intraclass correlation coefficient (ICC) to determine level of agreement.

The ARISTOTLE trial showed a risk reduction of stroke/systemic embolism (SE) and major bleeding in non-valvular atrial fibrillation (NVAF) patients treated with apixaban compared to warfarin. This retrospective study used four large US claims databases (MarketScan, PharMetrics, Optum, and Humana) of NVAF patients newly initiating apixaban or warfarin from January 1, 2013 to September 30, 2015. After 1:1 warfarin-apixaban propensity score matching (PSM) within each database, the resulting patient records were pooled. Kaplan-Meier curves and Cox proportional hazards models were used to estimate the cumulative incidence and hazard ratios (HRs) of stroke/SE and major bleeding (identified using the first listed diagnosis of inpatient claims) within one year of therapy initiation. The study included a total of 76,940 (38,470 warfarin and 38,470 apixaban) patients. Among the 38,470 matched pairs, 14,563 were from MarketScan, 7,683 were from PharMetrics, 7,894 were from Optum, and 8,330 were from Humana. Baseline characteristics were balanced between the two cohorts with a mean (standard deviation [SD]) age of 71 (12) years and a mean (SD) CHA2DS2-VASc score of 3.2 (1.7). Apixaban initiators had a significantly lower risk of stroke/SE (HR: 0.67, 95 % CI: 0.59-0.76) and major bleeding (HR: 0.60, 95 % CI: 0.54-0.65) than warfarin initiators. Different types of stroke/SE and major bleeding - including ischaemic stroke, haemorrhagic stroke, SE, intracranial haemorrhage, gastrointestinal bleeding, and other major bleeding - were all significantly lower for apixaban compared to warfarin treatment. Subgroup analyses (apixaban dosage, age strata, CHA2DS2-VASc or HAS-BLED score strata, or dataset source) all show consistently lower risks of stroke/SE and major bleeding associated with apixaban as compared to warfarin treatment. This is the largest "real-world" study on apixaban effectiveness and safety to date, showing that apixaban initiation was associated with significant risk reductions in stroke/SE and major bleeding compared to warfarin initiation after PSM. These benefits were consistent across various high-risk subgroups and both the standard- and low-dose apixaban dose regimens.

A total of 973 patients aged≥75 years with atrial fibrillation were recruited from primary care and randomly assigned to warfarin (n=488; target international normalized ratio, 2-3) or aspirin (n=485; 75 mg/d). Neither participants nor investigators were masked to group assignment. Follow-up was for a mean of 2.7 years (SD, 1.2). Cognitive outcome was assessed using the Mini-Mental State Examination at 9-, 21-, and 33-month follow-up. Participants who had a stroke were censored from the analysis, which was by intention to treat with imputation for missing data.

Coagulopathy in patients with traumatic brain injury (TBI) is a well-studied concept. Prothrombin complex concentrate (PCC) has been shown to be an effective treatment modality for correction of TBI coagulopathy. However, its use and effectiveness compared with recombinant factor VII (rFVIIa) in TBI has not been established. The purpose of this study was to compare PCC and rFVIIa for the correction of TBI coagulopathy.

Warfarin and apixaban were the two optimal treatment choices, as the other five treatment strategies including aspirin, dabigatran 110 mg, dabigatran in sequential dosages, dabigatran 150 mg, and rivaroxaban were strictly dominated on the efficiency frontier. Further, apixaban was a cost-effective alternative vs warfarin with an incremental cost of €2314 and an incremental quality-adjusted life year (QALY) of 0.189, corresponding to an incremental cost-effectiveness ratio (ICER) of €12,227/QALY.

This is a case report of an 83-year-old man in warfarin treatment with stable international normalised ratio (INR) after aortic valve replacement and atrial fibrillation. Due to back pain he took paracetamol (acetaminophen) 4 g/day, morphine 30 mg/day and diclofenac as rescue medication for two weeks. After 14 days of treatment he was admitted to a hospital with acute neurological deficits, and a blood sample showed INR levels above 10. A CT-scan of the brain showed an intracerebral haemorrhage. The patient died eight days after admission. Mechanisms of the possible interaction between paracetamol and warfarin are discussed.

A total of 695 patients with AF that were followed for ≥ 12 months (median 65.6 months, range 12-138 months), were analyzed retrospectively. The modified CHADS(2) score (MCS) was applied as follows. Each CHADS(2) score group was divided into 2 groups, A and B (i.e., MCS 0A vs 0B, and MCS 1A vs 1B) according to the number of nonmajor risk factors (female gender, chronic kidney disease, coronary artery disease, age 65-74 years). Group A had 0 or 1, and group B had 2 or more nonmajor risk factors.

Venous thromboembolism (VTE) prophylaxis is suboptimal, with many at-risk medical patients not receiving anticoagulants in hospital. Among those who receive anticoagulants in the hospital, thromboprophylaxis is frequently stopped at discharge despite persistent risk. Few studies have investigated prophylaxis use across the continuum of care. We analyzed anticoagulant use in medical patients in hospital and after discharge. Patient records (January 2005-December 2007) from medical patients with cancer, heart failure, severe lung disease, or infectious disease who were deemed at risk for VTE by the 2008 American College of Chest Physicians guidelines were included. Records were queried for inpatient and outpatient anticoagulant use by cross-matching data from the Premier Perspective discharge database with the i3/Ingenix LabRx outpatient and inpatient database. Of the 9675 medical patients identified, only 36.1% received inpatient anticoagulation (24.9% cancer patients, 30.1% infectious disease patients, 42.5% severe lung disease patients, and 56.3% heart failure patients). Of those who received in-hospital anticoagulants, most received enoxaparin (58.6%) followed by unfractionated heparin and other prophylactic agents. Only 1.8% of medical patients were prescribed anticoagulants within 30 days after discharge, ranging from 1.1% of patients with infectious disease to 4.8% of patients with heart failure. The majority of patients discharged who received outpatient anticoagulation filled prescriptions for warfarin, followed by enoxaparin plus warfarin. This real-world study demonstrates that only one-third of at-risk medical patients receive anticoagulants in hospital, with < 2% continuing to receive prophylaxis after discharge. Therefore, there is a need to improve the provision of thromboprophylaxis in the continuum of care for acutely ill medical patients.

A retrospective review of 1379 EVAR procedures was performed between the years of 2002 and 2009 at a single institution. The charts and radiographic images of all patients were reviewed. Patients who underwent EVAR with AAA morphology with short proximal necks were stratified into two groups: IF, Gore Excluder (W. L. Gore, Flagstaff, Ariz) group and SF, Cook Zenith (Cook, Bloomington, Ind) group. The primary end point for the study was the presence of proximal type 1 endoleaks. Secondary end points were graft migration at 1- and 2-year follow-up and aneurysm sac regression. The groups' demographics and comorbidities were also compared.

We reviewed the files of all patients 40 years old who underwent open or laparoscopic appendectomies from 2007 to 2010. Excluded were patients with short hospitalization and no follow-up of hemoglobin level, patients on warfarin treatment and patients who underwent additional procedures. Estimation of blood loss was based on decrease in hemoglobin level from admission to discharge. Risk factors for blood loss, such as anti-platelet therapy, age, gender, surgical approach, surgical time, surgical findings and complications, were analyzed.

Acute kidney injury due to glomerular bleeding has been described with IgA nephropathy and supratherapeutic warfarin anticoagulation. There is usually demonstrable tubular obstruction by erythrocyte casts associated with acute tubular injury. Although severe thrombocytopaenia increases the risk of bleeding, most cases of haematuria have been ascribed to non-glomerular or urological bleeding without a direct link to acute kidney injury. We describe a patient with acute kidney injury due to glomerular bleeding and tubular injury related to severe thrombocytopaenia, who was subsequently found to have thin basement membrane disease.

All national programs were positively associated with significant improvements in related prescribing or test request practice. The interventions to improve the use of antithrombotics resulted in a 1.27% (95% CI, 1.26%-1.28%) and 0.63% (95% CI, 0.62%-0.64%) relative increase in the use of aspirin or warfarin in the population with atrial fibrillation 6 and 12 months after the program, respectively, and in a 1.51% (95% CI, 1.49%-1.53%) relative increase in the use of aspirin as monotherapy for secondary stroke prevention 12 months after the intervention. The heart failure programs resulted in a 3.69% (95% CI, 3.67%-3.71%) relative increase in the use of low-dose spironolactone and a 4.31% (95% CI, 4.27%-4.35%) relative increase in the use of echocardiogram tests 12 months after the intervention.

Gerhard Levy started his investigations on the "Kinetics of Drug Action in Disease States" in the fall of 1980. The objective of his research was to study inter-individual variation in pharmacodynamics. To this end, theoretical concepts and experimental approaches were introduced, which enabled assessment of the changes in pharmacodynamics per se, while excluding or accounting for the cofounding effects of concomitant changes in pharmacokinetics. These concepts were applied in several studies. The results, which were published in 45 papers in the years 1984-1994, showed considerable variation in pharmacodynamics. These initial studies on kinetics of drug action in disease states triggered further experimental research on the relations between pharmacokinetics and pharmacodynamics. Together with the concepts in Levy's earlier publications "Kinetics of Pharmacologic Effects" (Clin Pharmacol Ther 7(3): 362-372, 1966) and "Kinetics of pharmacologic effects in man: the anticoagulant action of warfarin" (Clin Pharmacol Ther 10(1): 22-35, 1969), they form buy coumadin online a significant impulse to the development of physiology-based pharmacodynamic (PBPD) modeling as novel discipline in the pharmaceutical sciences. This paper reviews Levy's research on the "Kinetics of Drug Action in Disease States". Next it addresses the significance of his research for the evolution of PBPD modeling as a scientific discipline. PBPD models contain specific expressions to characterize in a strictly quantitative manner processes on the causal path between exposure (in terms of concentration at the target site) and the drug effect (in terms of the change in biological function). Pertinent processes on the causal path are: (1) target site distribution, (2) target binding and activation and (3) transduction and homeostatic feedback.

Previous surveys of orthopedic surgeons have shown considerable variation in thromboprophylaxis for venous thromboembolism after joint arthroplasty. This survey aimed to determine the current practice among Australian orthopedic surgeons. A questionnaire regarding the duration, reasons, and methods of chemical buy coumadin online and mechanical prophylaxis for hip and knee arthroplasty patients was sent to the 1082 surgeons identified; 593 (55%) members completed the questionnaire. The survey revealed that 98% of surgeons used chemical thromboprophylaxis, mainly low-molecular-weight heparin (84% hip and 79% knee). Those who use low-molecular-weight heparin were more likely to prescribe anticoagulants in fear of litigation (19.2% vs 10.1%, P = .04) and more likely to rely on protocols or guidelines (32.2% vs 17.2%, P = .004) instead of basing their decision on their own reading (52.4% vs 71.3%, P = .001). Most orthopedic surgeons in our survey have indicated that they would welcome guidelines from their association or college regarding thromboprophylaxis in arthroplasty.

Asian patients (n=2,782) were categorized according to baseline renal function or CHADS2 score, and efficacy and safety outcomes were analyzed for DE (110 mg and 150 mg b.i.d.) vs. warfarin. There was an increase in the rates of stroke/systemic embolism and major bleeding with worsening renal function and CHADS2 score. For stroke/systemic embolism (primary efficacy endpoint), there was no treatment interaction for dabigatran at either 110 or 150 mg b.i.d. compared with warfarin related to patients' baseline renal function (Pinteraction buy coumadin online =0.56 for DE 110 mg and 0.62 for DE 150 mg vs. warfarin) or CHADS2 score (Pinteraction=0.68 for DE 110 mg and 0.31 for DE 150 mg vs. warfarin). For major bleeding, there was no treatment interaction by creatinine clearance category observed for either dose (Pinteraction=0.60 and 0.62 for DE 110 mg and DE 150 mg, respectively). Baseline CHADS2 score had no significant effect on bleeding event rates with DE vs. warfarin.

Oral dabigatran was recently approved as an alternative to warfarin for prevention of stroke and buy coumadin online systemic embolism in patients with nonvalvular atrial fibrillation. Unlike warfarin, dabigatran has a fixed dosage and few drug interactions, and does not require anticoagulation monitoring or dietary restrictions.

The therapeutic landscape for anticoagulation management is undergoing a shift from the use of traditional anticlotting agents such as heparins and warfarin as the only options to the growing adoption of newer target-specific oral anticoagulants (TSOACs) with novel mechanisms of action. Dabigatran, the first TSOAC approved for use in the United States, is a direct competitive inhibitor of thrombin. It has predictable kinetics, with an elimination half-life of 12 to 17 hours in healthy volunteers. Apixaban and rivaroxaban are selective inhibitors of factor Xa, and also display first-order kinetics. In younger healthy individuals, apixaban has an apparent half-life of approximately 12 hours, whereas rivaroxaban has an elimination half-life of 5 to 9 hours. Understanding the pharmacologic properties of these newer drugs can lead to better insights regarding their respective safety and efficacy profiles and their application in clinical practice. Laboratory assessments have been developed to measure the anticoagulant efficacy of these newer agents. However, the results of these tests can be highly variable, and are therefore not always useful for monitoring the anticoagulation effects of these agents. In addition, several strategies have been documented for the potential reversal of the anticoagulant effects of these drugs, from the temporary discontinuation of an agent before elective surgery to suggested emergency procedures in the case of major bleeding events. New, specific reversal agents for dabigatran, apixaban, and rivaroxaban are currently being buy coumadin online developed, and dabigatran has received fast-track designation from the US Food and Drug Administration. Until comprehensive clinical guidelines are developed, institutions involved in emergency care should establish their own procedures for the management of patients undergoing anticoagulation who require emergency treatment. These protocols should include appropriate laboratory testing to assess anticoagulant activity as part of the inpatient workup if time allows, and the potential use of hemodialysis, prohemostatic agents, and reversal agents when available.

In the whole OAT group both warfarin and 3'-hydroxywarfarin correlate with INR at comparable degree (r2 = 0.0388 and 0.0362 respectively). Conversely, warfarin weekly dosage better correlates with warfarin than with 3'-hydroxywarfarin (r2 = 0.0975 and r2 = 0.0381 respectively), but considering together warfarin plus 3'-hydroxywarfarin the correlation strongly increased (r2 = 0.1114; p<0.0001). Interestingly, 3'-hydroxywarfarin reached a strong correlation at c4 respect to warfarin (r2 = 0.2157 and r2 = 0.0549; p = 0.0005 and p = 0.0944 respectively) seeming less affected by drug adjustments in the subgroup of 52 patients who started OAT. The multivariate analyses aimed at estimating the true contribution of 3'-hydroxywarfarin on INR buy coumadin online value ascribed it the unique significant value (p = 0.0021) in spite of warfarin who lost association. The pharmacogenetics studies confirmed that patients carrying the VKORC1 variant-allele required lower warfarin maintenance dosage and that the combination of VKORC1 and CYP2C9 yielded a warfarin responsive index (WRI) inversely related to the number variant alleles.

COPD was present in 1950 (10.8%) of 18,134 patients with data on pulmonary disease history. After multivariable adjustment, COPD was not associated with risk of stroke or systemic embolism (adjusted HR 0.85 [95% CI 0.60, 1.21], p=0.356). However, COPD was associated with a higher risk of all-cause mortality (adjusted HR 1.60 [95% CI 1.36, 1.88], p<0.001) and both cardiovascular and non-cardiovascular mortality. The benefit of apixaban over warfarin on stroke or systemic embolism was consistent among patients with and without COPD (HR 0.92 [95% CI 0.52, 1.63] versus 0.78 [95% CI 0.65, 0.95], interaction p=0.617).

Objective: Miscommunications between patients and providers can have serious consequences—especially where medications are concerned. Because oral anticoagulants are associated with preventable adverse events at disproportionately high rates, we used the model of anticoagulant care to examine the extent to which regimen discordance between patient and provider contributes to unsafe medication management. Methods: We performed a study among 220 long-term users of warfarin in an anticoagulation clinic to characterize the importance of two medication assessment components. We measured (1) adherence to warfarin by asking patients to report any missed doses during the prior 30 days, and (2) concordance between patients' and providers' reports of prescribed warfarin regimens. We categorized patients as having complete adherence if they missed no doses and regimen concordance if there was patient-provider agreement in the total weekly dosage. We examined the independent relationships between (a) adherence and anticoagulant outcomes, and (b) concordance and anticoagulant outcomes. We characterized anticoagulant outcomes as unsafe if international normalized ratio (INR) values either were < 2.0 (at risk for thrombosis) or > 4.0 (at risk for hemorrhage) over 90 days, using repeated measures analysis. Results: One hundred fifty-five patients (70.5 percent) reported no missed warfarin doses during the prior 30 days. In multivariate models, poor adherence was associated with under-anticoagulation (adjusted odds ratio [AOR] = 2.33; 95% confidence interval [CI] = 1.56–3.45; P < 0.001), but not with over-anticoagulation (AOR = 1.36; 95% CI = 0.69–2.66; P = 0.38). One hundred ten patients (50 percent) reported warfarin regimens that were discordant with respect to the clinicians' report. Among adherent patients, discordance was associated with both under-anticoagulation (AOR = 1.67; 95% CI = 1.00–2.78; P = 0.05) and over-anticoagulation (AOR = 3.44; 95% CI = 1.32–9.09; P = 0.01). There was no relationship between patients' reports of adherence and concordance (odds ratio [OR] = 1.14 95% CI = 0.64–2.04; P = 0.66). Conclusion: Discordance between clinicians and patients regarding warfarin regimens is unsettlingly common and places patients at risk for thromboembolic and hemorrhagic events. To promote safe and effective care, clinicians should sequentially determine adherence (missed doses) and regimen concordance during routine medication assessments. Systems need to be developed to ensure patient-provider concordance in medication regimens.
