Comparative Safety of Interleukin-1 Blockade With Anakinra in Patients With ST-Segment Elevation Acute Myocardial Infarction (from the VCU-ART and VCU-ART2 Pilot Studies)
Two pilot studies of interleukin-1 (IL-1) blockade in ST-segment elevation myocardial infarction (STEMI) showed blunted acute inflammatory response and overall favorable outcomes at 3 months follow-up. We hereby present a patient-level pooled analysis with extended follow-up of 40 patients with clinically stable STEMI randomized to anakinra, a recombinant IL-1 receptor antagonist, 100 mg/day for 14 days or placebo in a double-blinded fashion. End points included death, cardiac death, recurrent acute myocardial infarction (AMI), stroke, unstable angina, and symptomatic heart failure.Effects of Prolastin C (Plasma-Derived Alpha-1 Antitrypsin) on the Acute Inflammatory Response in Patients With ST-Segment Elevation Myocardial Infarction (from the VCU-Alpha 1-RT Pilot Study)
Alpha-1 antitrypsin (AAT) has broad anti-inflammatory and immunomodulating properties in addition to inhibiting serine proteases. Administration of human plasma–derived AAT is protective in models of acute myocardial infarction in mice. The objective of this study was to determine the safety and tolerability of human plasma–derived AAT and its effects on the acute inflammatory response in non-AAT deficient patients with ST-segment elevation myocardial infarction (STEMI). Ten patients with acute STEMI were enrolled in an open-label, single-arm treatment study of AAT at 60 mg/kg infused intravenously within 12 hours of admission and following standard of care treatment.
