چکیده

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 at 72 hours compared with baseline in MINOS (tPA, P=0.0022; non-tPA, P=0.0066) and was lower than in the non-MINOS comparison group at 24 hours (tPA, P<0.0001; non-tPA, P=0.0019). CONCLUSIONS Lower plasma matrix metalloproteinase-9 was seen among tPA-treated subjects in the MINOS trial. Combining minocycline with tPA may prevent the adverse consequences of thrombolytic therapy through suppression of matrix metalloproteinase-9 activity.

Effects of minocycline plus tissue plasminogen activator combination therapy after focal embolic stroke in type 1 diabetic rats.

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...

Extension of the thrombolytic time window with minocycline in experimental stroke.

BACKGROUND AND PURPOSE Thrombolysis with tPA is the only FDA-approved therapy for acute ischemic stroke. But its widespread application remains limited by narrow treatment time windows and the related risks of cerebral hemorrhage. In this study, we ask whether minocycline can prevent tPA-associated cerebral hemorrhage and extend the reperfusion window in an experimental stroke model in rats. ...

Effects of Minocycline Plus Tissue Plasminogen Activator Combination

Emerging evidence suggests that stroke comorbidities are associated with tissue plasminogen activator (tPA)–associated intracerebral hemorrhage (ICH) complication, a major limitation of tPA therapy. Clinical investigations have documented a correlation between increased ICH and worse neurological outcomes after tPA thrombolysis in stroke patients with diabetes mellitus or poststroke hyperglycem...
