Intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) therapy is being increasingly employed as an alternative to surgical intervention for the treatment of complicated parapneumonic effusions and empyema. Published cases are limited to one randomized control trial and few case reports. No data exist on employing sequential or repeated courses of intrapleural tPA/DNase t...
Thrombolysis for stroke is being used in some developing countries. This study was designed to evaluate the problems of thrombolysis therapy in Iran. During January-July 2008, all patients with ischemic stroke admitted to Ghaem Hospital, Mashhad, northeast Iran, were enrolled in a prospective observational study. Ghaem Hospital is a tertiary care hospital that includes infrastructure for thromb...
BACKGROUND AND PURPOSE Plasma matrix metalloproteinase-9 levels predict posttissue plasminogen activator (tPA) hemorrhage. METHODS The authors investigated the effect of minocycline on plasma matrix metalloproteinase-9 in acute ischemic stroke in the Minocycline to Improve Neurological Outcome in Stroke (MINOS) trial and a comparison group. RESULTS Matrix metalloproteinase-9 level decreased...
IMPORTANCE Intravenous tissue plasminogen activator (tPA) is known to improve outcomes in ischemic stroke; however, many patients may have been receiving antiplatelet therapy before acute ischemic stroke and could face an increased risk for bleeding when treated with tPA. OBJECTIVE To assess the risks and benefits associated with prestroke antiplatelet therapy among patients with ischemic str...
Intra-arterial therapy (IAT) for acute ischemic stroke has undergone great evolution during the past decade. While intra-venous therapy remains the standard of care for eligible patients, there are those patients in whom IV tPA is contraindicated, or those who fail to improve following IV tPA. In those cases, patients with accessible arterial occlusions may benefit from IAT, especially when rec...
BACKGROUND AND PURPOSE Thrombolytic therapy with tissue plasminogen activator (tPA) for acute ischemic stroke remains complicated by risks of hemorrhagic transformation. In this study we used a previously established quantitative rat model of tPA-associated hemorrhage to test the hypothesis that matrix metalloproteinases (MMPs) are involved. METHODS Spontaneously hypertensive rats were subjec...
Despite the US Food and Drug Administration's approval in 1996, tissue plasminogen activator (tPA) therapy for acute ischemic stroke remains substantially underused. We reviewed 3 potential reasons for low rates of tPA use: poor patient education, physicians' perceived risk of legal liability from negative patient outcomes, and insufficient reimbursement. The recent addition of diagnosis-relate...
BACKGROUND AND PURPOSE We assessed the effect of endovascular treatment in acute ischemic stroke patients with severe neurological deficit (National Institutes of Health Stroke Scale score, ≥20) after a prespecified analysis plan. METHODS The pooled analysis of the Interventional Management of Stroke III (IMS III) and Multicenter Randomized Clinical Trial of Endovascular Therapy for Acute Isc...
BACKGROUND AND PURPOSE Poststroke hyperglycemia is associated with resistance to tissue plasminogen activator (tPA) reperfusion, higher risk of intracerebral hemorrhage, and worse neurological outcomes. In this study, we asked whether minocycline combined with intravenous tPA may ameliorate inflammation and brain injury after focal embolic stroke in type 1 diabetic rats. METHODS Type 1 diabet...
