Systemic anticoagulation with unfractionated heparin is standard of care for patients receiving extracorporeal life support (ECLS); however, an alternative anticoagulant may be necessary when challenges with heparin therapy arise. Evidence for alternative anticoagulation in ECLS patients is limited. This retrospective analysis evaluated the dosing and outcomes associated with bivalirudin use in 14 adult ECLS patients. Indications for bivalirudin included heparin-induced thrombocytopenia, heparin resistance, or persistent clotting or bleeding while on heparin...

Bivalirudin (Angiomax; The Medicines Company, Parsippany, NJ), a direct thrombin inhibitor, has found increasing utilization as a heparin alternative in the pediatric population, most commonly for the treatment of thrombosis secondary to heparin-induced thrombocytopenia. Due to the relative rarity of heparin-induced thrombocytopenia as well as the lack of Food and Drug Administration-approved indications in this age group, much of what is known regarding the pharmacokinetics and pharmacodynamics of bivalirudin in this population has been extrapolated from adult data...

This paper describes a new pH-responsive peptide tag that adds a protein reversible precipitation and redissolution character. This peptide tag is a part of a cell surface protein B (CspB) derived from Corynebacterium glutamicum. Proinsulin that genetically fused with a peptide of N-terminal 6, 17, 50, or 250 amino acid residues of CspB showed that the reversible precipitation and redissolution depended on the pH. The transition occurred within a physiological and narrow pH range. A CspB50 tag comprising 50 amino acid residues of N-terminal CspB was further evaluated as a representative using other pharmaceutical proteins...

INTRODUCTION:  The rate of heparin-induced thrombocytopenia (HIT) on a population basis is unknown. The objective of this study was to characterize the risk for HIT during antepartum, delivery, and postpartum hospitalizations in the United States. MATERIALS AND METHODS: A large administrative database was used to determine the risk of HIT in hospitalized obstetric patients who received unfractionated heparin (UFH) or low molecular weight heparin (LMWH). Patients were presumed to have HIT if they were exposed to UFH or LMWH, received a diagnosis of HIT, and were administered a medication for the treatment of HIT including bivalirudin, argatroban, fondaparinux, or lepirudin...

The predictors of improvement in left ventricular ejection fraction (LVEF) after primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) are poorly understood. We sought to determine the prevalence and clinical and angiographic predictors of LVEF improvement after primary PCI in STEMI. In the Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction trial, 3,602 patients presenting with STEMI were randomized to heparin + a glycoprotein IIb/IIIa inhibitor versus bivalirudin...

BACKGROUND: Although the current practice guidelines recommend using both heparin and bivalirudin for percutaneous coronary interventions (PCI), the research data are ambiguous. AIM: To compare the impact of bivalirudin- and heparin on major clinical endpoints in PCI patients with particular emphasis on periprocedural stent thrombosis. METHODS: Total of 18 randomised clinical trials involving 41752 subjects were included. The endpoints comprised: net adverse clinical event (NACE: death, myocardial infarction [MI], unscheduled revascularisation, major bleeding [MB]), major adverse cardiovascular event (MACE: death, MI or stroke), acute/subacute stent thrombosis (ST)...

BACKGROUND: In the era of dual antiplatelet therapy of aspirin and clopidogrel and systematic stent implantation, glycoprotein IIb/IIIa inhibitors (GPI), including abciximab, eptifibatide and tirofiban, proved beneficial in improving early outcome of percutaneous coronary intervention (PCI), especially in higher risk clinical and/or anatomical subsets. This was associated however, with an increased incidence of bleeding complications. OBJECTIVE: To review whether the established results of GPI in PCI are maintained in the contemporary era of more effective antiplatelet agents (i...

Early intravenous anticoagulation is the corner stone treatment of patients admitted with an acute coronary syndrome: it antagonizes the ongoing coronary thrombosis and facilitates the percutaneous coronary intervention, hence a reduction of mortality and acute stent thrombosis. Unfractionated heparin, enoxaparin, bivalirudin and fondaparinux have been extensively studied in large randomized control trials and meta-analyses with the same objective: reducing the ischemic burden without hiking hemorrhagic events...

AIMS: The HEAT-PPCI trial compared bivalirudin and unfractionated heparin in patients undergoing Primary PCI. We report pre-specified, secondary analyses comparing the effects of P2Y12 inhibiting agents on platelet reactivity and clinical events. METHODS AND RESULTS: All patients received pre-procedural oral anti-platelet therapy. During the early stages of the trial, the P2Y12 inhibitor of choice was prasugrel with some use of clopidogrel. Later, routine therapy switched to ticagrelor...

BACKGROUND AND OBJECTIVE: Previous literature assessing ocular hemorrhagic complications of anticoagulant/antiplatelet medications in routine clinical practice is limited. This study evaluates the prevalence of spontaneous ocular hemorrhagic events associated with anticoagulation/antiplatelet therapy. PATIENTS AND METHODS: A retrospective study was performed to identify patients taking anticoagulants (rivaroxaban [Xarelto; Janssen Pharmaceuticals, Beerse, Belgium], bivalirudin [Angiomax; The Medicines Company, Parsippany, NJ], lepirudin [Refludan; Bayer HealthCare Pharmaceuticals, Berlin, Germany], dabigatran [Pradaxa; Boehringer Ingelheim, Ingelheim am Rhein, Germany], and argatroban) and antiplatelet agents (clopidogrel [Plavix; Bristol-Myers Squibb, New York City, NY], prasugrel [Effient; Lilly Medical, Indianapolis, IN], and ticagrelor [Brilinta; AstraZeneca, Cambridge, UK]) who presented for an eye examination...

Bivalirudin is a parenteral anticoagulant that elicits its effect through inhibition of both free and clot bound-thrombin. Inhibition of thrombin serves as a unique mechanism for anticoagulation when compared to heparin as thrombin serves as the final common pathway for the intrinsic and extrinsic coagulation cascades. Due to unclear benefit over heparin, concerns regarding reversibility, and most importantly cost its use as a parenteral anticoagulant varies by institution. A recent drug expenditure review within our institution noted a significant increase in the contribution bivalirudin had on the overall drug budget...

Cangrelor is an intravenously administered P2Y12 receptor antagonist with very fast, potent, and quickly reversible action. In the CHAMPION PHOENIX trial, cangrelor provided an improved anti-ischemic protection compared with clopidogrel, without increasing the risk of severe bleeding. Cangrelor is currently approved by drug regulating authorities for patients undergoing percutaneous coronary intervention (PCI) without prior treatment with a P2Y12 receptor antagonist and not receiving a glycoprotein IIb/IIIa inhibitor, while its use is endorsed with a class IIb recommendation by the European Society of Cardiology guidelines...

BACKGROUND: Since older age is a strong predictor of not only bleeding but also of ischemic events, understanding the risk:benefit profile of bivalirudin in the elderly undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation (STEMI) is important. For this, we aim to compare elderly with young patients, who all underwent pPCI for STEMI and randomly received either bivalirudin or heparin. METHODS: We performed a patient-level pooled analysis (n=5800) of two large randomized trials...
