Gangliosides for acute ischemic stroke.

چکیده
BACKGROUND Gangliosides may have a protective effect on the central and peripheral nervous systems. OBJECTIVES The objective of this review was to assess the effect of exogenous gangliosides in acute ischaemic stroke. SEARCH STRATEGY We searched the Cochrane Stroke Group trials register (last searched: May 2001) and contacted drug companies and main investigators of included trials. SELECTION CRITERIA Randomised trials of gangliosides compared with placebo or standard treatment in people with definite or presumed ischaemic stroke. Trials were included if people were randomised within 15 days of symptom onset and if mortality data were available. DATA COLLECTION AND ANALYSIS One reviewer applied the inclusion criteria. Two reviewers independently extracted the data. Trial quality was assessed. MAIN RESULTS Twelve trials involving 2265 people were included. All the trials tested purified monosialoganglioside GM1. Only three trials described the randomisation procedure. Follow-up was between 15 to 180 days. Death at the end of follow-up showed no significant difference (odds ratio 0.91, 95% confidence interval 0.73 to 1.13). There was no difference shown between early (within 48 hours) and delayed treatment. For disability, three trials did not show any improvement in Barthel index score with gangliosides (weighted mean difference 2.1; 95% confidence interval -4.8 to 8.9). In two trials, eight patients experienced adverse effects that led to discontinuation of ganglioside treatment, seven had skin reactions and one developed Guillain-Barré syndrome. REVIEWER'S CONCLUSIONS There is not enough evidence to conclude that gangliosides are beneficial in acute stroke. Caution is warranted because of reports of sporadic cases of Guillain-Barré syndrome after ganglioside therapy.

Introduction: Swallowing dysfunction complicates acute strokes in 25-32% of cases and directly affects patientschr('39') prognosis and recovery. Dysphagia complicates the course of acute strokes through its potential of the development of chest infection, nutritional problems, and dehydration. Dysphagia is also an independent predictor of respiratory morbidity and mortality in acute stroke. In...

Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
متن کاملP 149: Effect of Glycoprotein IIb/IIIa Inhibition on Acute Ischemic Stroke Injuries
Ischemic stroke accounts for about 87 percent of all cases. It occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. It is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. We know that most of the injuries after an acute ischemic s...
