Oral citicoline in acute ischemic stroke: an individual patient data pooling analysis of clinical trials.

摘要

BACKGROUND AND PURPOSE: No single neuroprotective agent has been shown to influence outcome after acute stroke. Citicoline has been studied worldwide in many clinical trials with positive findings, but only 1 trial has obtained significant results in the primary efficacy variables. Our objective was to evaluate the effects of oral citicoline in patients with acute ischemic stroke by a data pooling analysis of clinical trials. The primary efficacy end point chosen was the common evaluation of recovery, combining National Institutes of Health Stroke Scale /=95 at 3 months using the generalized estimating equations analysis. METHODS: A systematic search of all prospective, randomized, placebo-controlled, double-blind clinical trials with oral citicoline (MEDLINE, Cochrane, and Ferrer Group bibliographic databases) was undertaken. Individual patient data were extracted from each study and pooled in a single data file. The main inclusion criteria included compatible neuroimaging with ischemic stroke, National Institutes of Health Stroke Scale >/=8, and prior modified Rankin Scale score
