What doses of thromboprophylaxis are appropriate for adult patients at extremes of body weight?

UKMi

Bivalirudin, glycoprotein inhibitor, and heparin use and association with outcomes of primary percutaneous coronary intervention in the United Kingdom

Analysis of UK national PCI registry (n=61,138 procedures) noted no significant difference in short- or medium-term mortality between ST elevation myocardial infarction patients treated with bivalirudin vs. heparin-plus-glycoprotein inhibitors at primary PCI.

 

Time to Reperfusion and Treatment Effect for Acute Ischemic Stroke A Randomized Clinical Trial

JAMA Neurology

RCT (n=500) found that for every hour of reperfusion delay, the initially large benefit of intra-arterial treatment decreases, with the absolute risk
difference for a good outcome being reduced by 6% per hour of delay.

Treatment for superficial infusion thrombophlebitis of the upper extremity

Cochrane Database of Systematic Reviews

Review of 13 studies (n=917) of a topical (11 studies), an oral and a parenteral treatment noted that evidence for treating acute infusion superficial thrombophlebitis is limited and of low quality and is insufficient to recommend the use of any of the treatments studied.

 

Polypharmacy and the Efficacy and Safety of Rivaroxaban versus Warfarin in the Prevention of Stroke in Patients With Nonvalvular Atrial Fibrillation

Circulation

In a population of patients in ROCKET AF, polypharmacy was not linked to higher risk of stroke or non-CNS embolism (NCE), but it was linked
to higher risks of combined endpoint of stroke, NCE, vascular death, or MI, and non-major clinically relevant or major bleeding.

 

Early Clinical and Radiological Course, Management, and Outcome of Intracerebral Hemorrhage Related to New Oral Anticoagulants

JAMA Neurology

In this observational study of 61 patients with non-traumatic NOAC-associated intracerebral haemorrhage admitted between 2012 and 2014 it
is reported that mortality was 28% and 65% of survivors had an unfavourable outcome at 3 months. Haematoma expansion occurred in 38%.

 

Safety of antithrombotic drugs in patients with atrial fibrillation and non-end-stage chronic kidney disease: Meta-analysis and systematic review

Thrombosis Reasearch

This review of 12 studies showed no significant difference in bleeding risk between warfarin and antiplatelets (RR 1.05; 95% CI = 0.74 to
1.36), but reduced bleeding risk with direct oral anticoagulants compared to warfarin (RR 0.81; 95% CI = 0.75 to 0.88).

 

Early time courses of recurrent thromboembolism and bleeding during apixaban or enoxaparin/warfarin therapy – sub-analysis of the AMPLIFY trial

Thrombosis and Haemostasis

Analysis of data from this RCT (n=5,395) comparing apixaban to enoxaparin followed by warfarin for treating venous thromboembolism showed
apixaban to be non-inferior at 7, 21, 90 days and 6 months and that the reduced bleeding risk with apixaban began early during treatment.

Primary Care Atrial Fibrillation Service: outcomes from consultant-led anticoagulation assessment clinics in the primary care setting in the UK

BMJ Open

Service was delivered in 56 GP practices. Eligible patients on anticoagulation improved from 77% to 95% (p<0.0001). Audit of 8 practices after 195 days showed 90% continued treatment; ~30–35 strokes/year may have been prevented in these previously under-treated high-risk patients.

 

Association between use of warfarin with common sulfonylureas and serious hypoglycemic events: retrospective cohort analysis

British Medical Journal

Study of 465,918 Medicare fee for service beneficiaries noted a substantial positive link between use of warfarin (WF) with glipizide/glimepiride and hospital admission/emergency department visits for hypoglycemia and related diagnoses, particularly in patients first starting WF.

 

The ORBIT bleeding score: a simple bedside score to assess bleeding risk in atrial fibrillation

European Heart Journal

In this report of a validation of a new risk-scoring tool to assess bleeding risk in patients with AF, it is claimed that the five-element ORBIT bleeding risk score had better ability to predict major bleeding than either HAS-BLED and ATRIA risk scoring tools.

 

A Multinational Trial of Prasugrel for Sickle Cell Vaso-Occlusive Events

New England Journal of Medicine

In this RCT, 341 patients with sickle cell anaemia (aged 2 – 17) were randomised to receive prasugrel or placebo. At the end of the trial no significant differences were seen in the primary end-point of vaso-occlusive crises (2.30 vs 2.77 per patient per year).

 

Safety and effectiveness of oral rivaroxaban versus standard anticoagulation for the treatment of symptomatic deep-vein thrombosis (XALIA): an international, prospective, non-interventional study

The Lancet Haematology

In this real-life comparison of outcomes in patients receiving rivoroxaban (RV) (n=2619) or standard anticoagulation (n=2149) it was reported that although RV patients had a lower baseline risk, adjusted analyses show it to be a safe and effective alternative to standard treatment.

 

Oral antiplatelet agents – are they safe in breastfeeding?

UKMi

This updated medicines Q&A provides advice on the safety of oral antiplatelet agents in breastfeeding mothers.

 

Antithrombotic therapy in the elderly: expert position paper of the European Society of Cardiology Working Group on Thrombosis

European Heart Journal

Heart failure and risk of venous thromboembolism: a systematic review and meta-analysis

The Lancet Haematology

Review of 71 studies found heart failure is a common independent risk factor for venous thromboembolism, with overall relative risk of 1.51 (1.36–1.68). Researchers suggest thromoboprophylaxis should be considered in clinical practice for high-risk patients.

 

Data on phase III ROCKET-AF trial of rivaroxaban to be reanalysed after discovery investigators used faulty point of care device (INRatio)

British Medical Journal

The device has been subject to recall following reports it could deliver INR results "clinically significantly lower" vs. laboratory INR method. This could have made rivaroxaban appear safer in terms of bleeding risk. European Medicines Agency has launched investigation.

 

What are the risks of using antiplatelet agents in combination with the Novel Oral Anticoagulants (NOACs) in patients with atrial fibrillation, and how should the potential risks be managed?

US Food and Drug Administration

This review stated that long-term use (12 months or longer) of clopidogrel does not increase or decrease overall risk of death in patients with, or at risk for, heart disease. The evaluation also does not suggest that clopidogrel increases the risk of cancer or death from cancer.
