title: Citicoline for acute ischemic stroke in Mexican hospitals: a retrospective postmarketing analysis.
abstract: Some neuroprotective agents have shown benefits in animal models, but disappointing results in humans. Citicoline is used in several countries as coadjuvant treatment in acute ischemic stroke (AIS) patients; however, there are no retrospective postmarketing surveillances on the experience of citicoline in Mexico. The aim of this study was to evaluate the correlation between citicoline exposure and functional outcome at discharge and at 30 and 90 days post-stroke, in a retrospective case-control design on systematic descriptive databases from three referral hospitals. Clinical records of 173 consecutively registered patients were analyzed, 86 of whom were treated with citicoline within the first 48 h after AIS and the remaining 87 were untreated, randomly selected controls matched for age (+/- 5 years), gender and NIHSS (+/- 1 point) at hospital admission. Pretreatment conditions were similar between groups. Compared with controls, exposure to citicoline was associated with a significantly lower 30-day mean and median modified Rankin score (in both, P < 0.05). After paired multivariate analyses (controlled for NIHSS, age, gender, hospital arrival in < 24 h, thrombolysis and comorbidities) citicoline was independently associated with a lower 90-day mortality risk (P = 0.047) and with fewer in-hospital complications (mainly infections and sepsis, P = 0.001). In this observational study, citicoline use was associated with a better functional status and lower rates of short-term mortality, possibly due to fewer in-hospital systemic complications. The putative benefits should be interpreted as clinical associations, since this is not a randomized, controlled clinical trial.
