OBJECTIVE: This study analyzed the efficacy and safety of low-dose and standard-dose alteplase intravenous thrombolytic therapy for acute ischemic stroke (AIS). METHODS: Patients with AIS who underwent intravenous alteplase thrombolysis from July 2012 to December 2016 were retrospectively analyzed and correspondingly divided into low-dose (0.6-0.89 mg/kg) group and standard-dose group (0.9 mg/kg) according to alteplase dosage. The clinical outcome was evaluated by modified Rankin Scale (mRS) at 90 days after onset...

BACKGROUND: About 5% to 10% of all deep vein thromboses occur in the upper extremities. Serious complications of upper extremity deep vein thrombosis, such as post-thrombotic syndrome and pulmonary embolism, may in theory be avoided using thrombolysis. No systematic review has assessed the effects of thrombolysis for the treatment of individuals with acute upper extremity deep vein thrombosis. OBJECTIVES: To assess the beneficial and harmful effects of thrombolysis for the treatment of individuals with acute upper extremity deep vein thrombosis...

BACKGROUND Our previous study found that lower lymphocyte-to-monocyte ratio (LMR) is an independent risk factor of clinical outcome of acute ischemic stroke (AIS). However, whether lower LMR is independently associated with adverse prognosis of AIS treated with thrombolysis has not been determined. In this study, we explored the relationship between LMR and prognosis of AIS treated with thrombolysis. MATERIAL AND METHODS We retrospectively enrolled 108 patients treated with thrombolysis. LMR was calculated according to lymphocyte count and monocyte count on admission...

Natto, a fermented soybean food, has been consumed by oriental people for more than 1000 years. Nattokinase, formerly called subtilisin NAT is a well studied protease of microbial origin that possesses fibrinolytic (anti-clotting) activities. Due to its strong fibrinolytic and thrombolytic activity, Nattokinase is regarded as a precious dietary supplement or nutraceutical for the oral thrombolytic therapy. Nattokinase is witnessed to be a useful enzyme for the com-plete removal of the vitreous and associated proliferative tissues in proliferative vitreo retinal disorders...

Injection of recombinant tissue plasminogen activator (rt-PA) is the standard drug treatment for thrombolysis. However, rt-PA shows risk of hemorrhages and limited efficiency even at high doses. Polysaccharide-poly(isobutylcyanoacrylate) nanoparticles functionalized with fucoidan and loaded with rt-PA were designed to accumulate on the thrombus. Fucoidan has a nanomolar affinity for the P-selectin expressed by activated platelets in the thrombus. Solid spherical fluorescent nanoparticles with a hydrodynamic diameter of 136 ± 4 nm were synthesized by redox radical emulsion polymerization...

Extensive research over the last two decades has advanced our understanding of the pathophysiology of ischemic stroke. However, current pharmacologic therapies are still limited to rapid reperfusion using thrombolytic agents, and neuroprotective approaches that can reduce the consequences of ischemic and reperfusion injury, are still not available. To bridge this gap, we have evaluated the long-term efficacy and therapeutic time window of a novel peptide-based neuroprotectant TAT-STEP, derived from the brain-enriched and neuron-specific tyrosine phosphatase STEP...

Ischemic stroke can result from blockage of blood vessels, forming fibrin clots in the body and causing irreparable brain damage. Remedial thrombolytic agents or anticoagulants have been studied; however, because the FDA-approved tissue plasminogen activator (t-PA) has low efficacy and side effects, it is necessary to develop safer and more effective treatment candidates. This study was aimed at assessing the fibrinolytic and anticoagulation features of a novel serine protease extracted and purified from Diopatra sugokai, a polychaeta that inhabits tidal flats...

The analysis of misdiagnosis of stroke has become increasingly relevant because of the time pressure in the thrombolytic treatment of ischemic strokes. Within the narrow time window of thrombolysis, a false-positive stroke diagnosis can lead to a faulty and potentially dangerous thrombolysis. The terms "Stroke Mimic" (SM = false-positive stroke diagnosis) and "Stroke Chameleon" (SC = false-negative stroke diagnosis) have been introduced for misdiagnosis in this field. The rate of SM decreases during the treatment phases from approximately 50 % in the preclinical situation to approximately 2-10 % in the Stroke Unit indicating thrombolytic therapy...

Cardiovascular disorder occurs when a local blood clot obstructs an artery or a vein to its surround organs, causing related tissues to lose function and die. It is one of the leading causes of mortality and a major cause of disability. The effect of thrombolysis induced by injecting intravenous thrombolytic agents is critical for reducing tissue damages. Streptokinase (SK) is a widely used thrombolytic agent in the treatment of thromboembolism in the blood vessels. A high unit of streptokinase is used in thrombolytic therapies for thrombotic disorders and could improve tissue reperfusion...

Despite the availability of thrombolytic and endovascular therapy for acute ischemic stroke, many patients are ineligible due to delayed hospital arrival. The identification of factors related to either early or delayed hospital arrival may reveal potential targets of intervention to reduce prehospital delay and improve access to time-critical thrombolysis and clot retrieval therapy. Here, we have reviewed studies reporting on factors associated with either early or delayed hospital arrival after stroke, together with an analysis of stroke onset to hospital arrival times...

Prosthetic valve thrombosis (PVT) is a life-threatening complication in pregnant women with mechanical prosthetic heart valves. Thrombolytic therapy (TT) has evolved as an effective treatment alternative to surgery, which is associated with very high maternal and fetal mortality and morbidity in these patients. Acute ischemic stroke may rarely occur during TT for PVT. Here, we present a pregnant patient who was complicated with cerebral thromboembolism during TT for PVT and successfully managed with continuation of TT...

BACKGROUND: Intravenous tissue plasminogen activator (IV tPA) was shown to be an effective treatment for acute ischemic stroke (AIS). According to stroke guidelines, there is no need to wait for the complete blood count (CBC) and coagulation test results before application of IV alteplase if there is no suspected coagulation disorder. In this study, a patient with AIS and thrombotic thrombocytopenic purpura (TTP) symptoms during thrombolytic treatment was presented. CASE: A 33-year-old male patient was admitted at the 2...

Thrombolytic treatment (recombinant tissue plasminogen activator [rt-PA]) has established efficacy in acute ischemic stroke, but pregnancy has been an exclusion criterion for all clinical trials that validated alteplase in acute stroke, so our knowledge about its use in this condition is limited. Herein we report the successful use of intravenous rt-PA thrombolysis, uncomplicated by neither hemorrhage development nor other complication in a woman who was 13 weeks pregnant with acute ischemic stroke. The brain magnetic resonance imaging diffusion-weighted sequences showed increased signal in the territory of the left middle cerebral artery...
