Antiplatelet and anticoagulant agents for primary prevention of thrombosis in individuals with antiphospholipid antibodies

ABSTRACT: Abstract This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effects of antiplatelet and anticoagulant agents versus placebo or no intervention or other intervention for the development of thrombosis in people with antiphospholipid (aPL) antibodies but who have not had a thrombotic event.

Prevention of thrombosis in antiphospholipid syndrome.

Project description:Antiphospholipid syndrome (APS) is an acquired autoimmune condition characterized by thrombotic events, pregnancy morbidity, and laboratory evidence of antiphospholipid antibodies (aPL). Management of these patients includes the prevention of a first thrombotic episode in at-risk patients (primary prevention) and preventing recurrent thrombotic complications in patients with a history of thrombosis (secondary prevention). Assessment of thrombotic risk in these patients, balanced against estimated bleeding risks associated with antithrombotic therapy could assist clinicians in determining whether antithrombotic therapy is warranted. Thrombotic risk can be assessed by evaluating a patient's aPL profile and additional thrombotic risk factors. Although antithrombotic options for secondary prevention of venous thromboembolism (VTE) have been evaluated in clinical trials, studies in primary prevention of asymptomatic aPL-positive patients are needed. Primary prevention with aspirin may be considered in asymptomatic patients who have a high-risk aPL profile, particularly if additional risk factors are present. Secondary prevention with long-term anticoagulation is recommended based on estimated risks of VTE recurrence, although routine evaluation of thrombotic risk can assist in determining whether ongoing anticoagulation is warranted. Studies that stratify thrombotic risk in aPL-positive patients, and patients with APS evaluating antithrombotic and non-antithrombotic therapies will be useful in optimizing the management of these patients.

Antiplatelet agents for stroke prevention.

Project description:Stroke is one of the leading causes of disability and death. Ischemic stroke is a syndrome with heterogeneous mechanisms and multiple etiologies, rather than a singularly defined disease. Approximately one third of ischemic strokes are preceded by another cerebrovascular ischemic event. Stroke survivors are at high risk of vascular events (i.e., cerebrovascular and cardiovascular events), particularly during the first several months after the ischemic event. The use of antiplatelet agents remains the fundamental component of secondary stroke prevention. Based on the available data, antiplatelet agents should be used for patients with noncardioembolic stroke. The use of combination therapy (aspirin plus clopidogrel) has not been proven to be effective or safe to use for prevention of early stroke recurrence or in long-term treatment. There is no convincing evidence that any of the available antiplatelet agents are superior for a given stroke subtype. Currently, the uses of aspirin, clopidogrel, or aspirin combined with extended release dipyridamole are all valid alternatives after an ischemic stroke or transient ischemic attack. However, to maximize the effects of these agents, the treatment should be initiated as early as possible and be continued on a lifelong basis.

Gastrointestinal endoscopy in patients on anticoagulant therapy and antiplatelet agents.

Project description:Periprocedural management of antithrombotics for gastrointestinal endoscopy is a common clinical issue, given the widespread use of these drugs for primary and secondary cardiovascular prevention. For diagnostic procedures, with or without biopsy, no adjustments in antithrombotics are usually needed. For operative procedures, balancing the risk of periprocedural hemorrhage with the continuation of antithrombotics against the chance of recurrent thromboembolic events with their discontinuation may be challenging. Oral anticoagulants need to be temporarily withheld, and consideration must be given to whether a periendoscopic "bridge" therapy, typically a low-molecular-weight heparin, should be used in order to minimize the risk of thromboembolic events. Although some emerging evidence has shown that patients receiving heparin bridging appear to be at increased risk of overall and major bleeding and at similar risk of thromboembolic events compared to controls, bridging therapy is still recommended for patients on vitamin K antagonists who are at high thrombotic risk. Conversely, bridging therapy is usually not needed for patients taking new oral agents, which are characterized by shorter half-lives, and a rapid offset and onset of action. Management of antiplatelet therapy requires special care in patients on secondary prevention, especially those with coronary stents. This review is intended to summarize the recommendations of updated International Guidelines designed to help the decision-making process in such an intricate field.

Antiphospholipid antibodies and recurrent thrombosis after a first unprovoked venous thromboembolism.

Project description:It is uncertain whether antiphospholipid antibodies (APAs) increase the risk of recurrence after a first unprovoked venous thromboembolism (VTE). We tested for anticardiolipin antibodies, anti-β2 glycoprotein 1 antibodies, and lupus anticoagulant on 2 occasions ∼6 months apart in 307 patients with a first unprovoked VTE who were part of a prospective cohort study. We then determined if APAs were associated with recurrent thrombosis in the 290 patients who stopped anticoagulant therapy in response to negative D-dimer results. Compared with those without an APA, the hazard ratios for recurrent VTE were 1.8 (95% confidence interval [CI], 0.9-3.7; P = .09) in the 25.9% of patients with an APA on ≥1 occasions, 2.7 (95% CI, 1.1-.7; P = .03) in the 9.0% of patients with the same APA on 2 occasions, and 4.5 (95% CI, 1.5-13.0; P = .006) in the 3.8% of patients with 2 or 3 different APA types on either the same or different occasions. There was no association between having an APA and D-dimer levels. We conclude that having the same type of APA on 2 occasions or having >1 type of APA on the same or different occasions is associated with recurrent thrombosis in patients with a first unprovoked VTE who stop anticoagulant therapy in response to negative D-dimer tests. APA and D-dimer levels seem to be independent predictors of recurrence in patients with an unprovoked VTE. This trial was registered at www.clinicaltrials.gov as #NCT00720915.

Review of atrial fibrillation outcome trials of oral anticoagulant and antiplatelet agents.

Project description:Atrial fibrillation (AF) is strongly associated with cardioembolic stroke, and thromboprophylaxis is an established means of reducing stroke risk in patients with AF. Oral vitamin K antagonists such as warfarin have been the mainstay of therapy for stroke prevention in patients with AF. However, they are associated with a number of limitations, including excessive bleeding when not adequately controlled. Antiplatelet agents do not match vitamin K antagonists in terms of their preventive efficacy. Dual-antiplatelet therapy (clopidogrel and acetylsalicylic acid) or combined antiplatelet-vitamin K antagonist therapy in AF has also failed to provide convincing evidence of their additional benefit over vitamin K antagonists alone. Novel oral anticoagulants, including the direct thrombin inhibitor dabigatran and direct Factor Xa inhibitors such as rivaroxaban, apixaban, and edoxaban, have now been approved or are currently in late-stage clinical development in AF. These newer agents may provide a breakthrough in the optimal management of stroke risk.
