Verapamil as an Adjunct Therapy to Reduce tPA Toxicity in Hyperglycemic Stroke: Implication of TXNIP/NLRP3 Inflammasome.

Mol Neurobiol 2021 Apr 13. Epub 2021 Apr 13.

Department of Anatomy and Neurobiology, College of Medicine, The University of Tennessee Health Science Center, 875 Monroe Avenue, Wittenborg Bldg, Room-231, Memphis, TN, 38163, USA.

Thrombolytic therapy has remained quite challenging in hyperglycemic patients for its association with poor prognosis and increased hemorrhagic conversions. We recently showed that tissue plasminogen activator (tPA)-induced cerebrovascular damage is associated with thioredoxin-interacting protein (TXNIP) upregulation, which has an established role in the detrimental effects of hyperglycemia. In the present work, we investigated whether verapamil, an established TXNIP inhibitor, may provide protection against hyperglycemic stroke and tPA-induced blood-brain barrier (BBB) disruption.

Improvement in plasma D-dimer level in severe SARS-CoV-2 infection can be an indicator of fibrinolysis suppression: Case reports.

Medicine (Baltimore) 2021 Apr;100(15):e25255

Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center, Los Angeles, CA.

Rationale: Fibrinolysis shutdown associated with severe thrombotic complications is a recently recognized syndrome that was previously seldom investigated in patients with severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. It presents a unique therapeutic dilemma, as anticoagulation with heparin alone is insufficient to address the imbalance in fibrinolysis. And while the use of fibrinolytic agents could limit the disease severity, it is often associated with bleeding complications. Read More

Thrombolytic strategies for ischemic stroke in the thrombectomy era.

J Thromb Haemost 2021 Apr 9. Epub 2021 Apr 9.

Normandie Univ, UNICAEN, INSERM, PhIND "Physiopathology and Imaging of Neurological Disorders", Institut Blood and Brain @ Caen-Normandie, Cyceron, 14000, Caen, France.

Twenty-five years ago, intravenous thrombolysis has revolutionized the care of patients with acute ischemic stroke. Since 2015, randomized clinical trials have demonstrated that mechanical thrombectomy improves functional outcome in stroke patients over intravenous thrombolysis alone. More recently, three randomized clinical trials have suggested that mechanical thrombectomy alone is non-inferior to a combined strategy with both intravenous thrombolysis and mechanical thrombectomy.

Treatment challenges in patients with early acute massive pulmonary thrombosis embolism (PTE) after lung cancer surgery: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25371

Department of Respiratory and Critical Care Medicine, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.

Introduction: Early acute massive pulmonary thrombosis embolism (PTE) after lung cancer surgery is one of the most fatal surgical complications. It is often accompanied by shock and hypotension, with high mortality rate. Due to surgical wounds, patients with early acute massive PTE after lung cancer surgery have a high risk of thrombolytic bleeding, which renders treatment more challenging and there is currently no standard protocol on how to safely and effectively treat these patients in the clinic.

Plasmin-resistant PSD-95 inhibitors resolve effect-modifying drug-drug interactions between alteplase and nerinetide in acute stroke.

Sci Transl Med 2021 Apr;13(588)

NoNO Inc., Toronto, Ontario M5V 1E7, Canada.

Neuroprotection for acute ischemic stroke is achievable with the eicosapeptide nerinetide, an inhibitor of the protein-protein interactions of the synaptic scaffolding protein PSD-95. However, nerinetide is subject to proteolytic cleavage if administered after alteplase, a standard-of-care thrombolytic agent that nullifies nerinetide's beneficial effects. Here, we showed, on the basis of pharmacokinetic data consistent between rats, primates, and humans, that in a rat model of embolic middle cerebral artery occlusion (eMCAO), nerinetide maintained its effectiveness when administered before alteplase.
