Bivalirudin (“Angiomax”): Rescue Therapy in Covid Cases

Given the low platelet counts in patients with blood clots arising from Heparin-induced thrombocytopenia (HIT)  in severe COVID191 or clots induced by Ad26.COV2.S vaccination, heparin is not a viable treatment. Alternative thrombin inhibitors are often sought out. Bivalrudin is a 20-residue peptide derived from the saliva of the leech and is a specific, reversible, direct thrombin inhibitor and an effective anticoagulant.  In a journal pre-proof in The Annals of Emergency Medicine, doctors describe the recent successful use of bivalirudin:

It has also been reported to successfully to manage severe hypoxemic and hypercarbic respiratory failure requiring Venovenous Extracorporeal Membrane Oxygenation:
