Activation of the tissue factor (TF) pathway of blood coagulation is associated with increased blood thrombogenicity and increases in markers of blood coagulation levels may in part explain the high degree of poor neurological outcome and recurrence of stroke in patients with acute ischemic stroke (AIS). It has been shown that membrane-bound tissue factor procoagulant activity (TF-PCA) and plasma activated factor VII (FVIIa) and markers of thrombin generation, prothrombin fragment 1.2 (F1.2) and thrombin-antithrombin complexes (TAT), are markedly elevated after AIS1. While these markers are highest in patients with type 2 diabetes mellitus (T2DM) and hyperglycemia, the effect of blood glucose (BG) control on levels of blood coagulation markers and their relationship with stroke outcome is unknown. Therefore, a better understanding of the relationships between these and other markers of blood coagulation and clinical outcomes after stroke and how hyperglycemia control modulates these markers holds great promise for management of acute ischemic stroke. The Insights on Selected Procoagulation Markers and Outcomes in Stroke Trial (I-SPOT): Response to Insulin Administration and Blood Glucose Control proposal is designed to accompany the Stroke Hyperglycemia Insulin Network Effort (SHINE) clinical trial, a Phase III multicenter, randomized, controlled trial planning to determine the efficacy and validate the safety of glycemic control in stroke patients. The SHINE trial will recruit 1,400 AIS patients with Type II diabetes mellitus (T2DM) and hyperglycemia, each receiving 3 days of hyperglycemia control with intravenous (IV) insulin therapy or control therapy with subcutaneous (SQ) insulin. The I-SPOT trial will recruit 315 SHINE patients. Blood coagulation marker levels will be measured before and at 48 hours after the start of treatment. Baseline and temporal changes in biomarkers levels will be compared between SHINE treatment groups.
