    Abstract:
    BACKGROUND: The role of adiponectin, leptin, and resistin and the -420C>G polymorphism of the resistin gene promoter in the pathogenesis of ischemic stroke are controversial. We aimed to evaluate whether serum levels of these adipokines and the -420C>G polymorphism are associated with ischemic stroke severity and in-hospital outcome. METHODS: We prospectively studied 93 patients who were consecutively hospitalized for acute ischemic stroke (39.8% males, age 79.7 ± 6.3 years). Stroke severity was evaluated at admission by the National Institutes of Health Stroke Scale (NIHSS). In-hospital outcome was evaluated by dependency rates at discharge and in-hospital mortality. RESULTS: The G allele was more prevalent in patients with severe stroke (P < .05). Independent predictors of severe stroke were high-sensitivity C-reactive protein levels (relative risk [RR] 1.43, 95% confidence interval [CI] 1.08-1.91, P < .05). Patients with dependency at discharge had lower serum leptin levels (P < .05). Independent predictors of functional dependence were prior ischemic stroke (RR 7.55, 95% CI 1.69-33.58, P < .01), serum triglyceride levels (RR .98, 95% CI .96-0.99, P < .05), and NIHSS at admission (RR 1.47, 95% CI 1.17-1.84, P < .001). The G allele was more prevalent in patients who died (P < .05). Independent predictors of in-hospital mortality were systolic blood pressure (RR 1.09, 95% CI 1.01-1.19, P < .05) and NIHSS at admission (RR 1.26, 95% CI 1.08-1.48, P < .005). CONCLUSIONS: The G allele of the -420C>G polymorphism of the resistin gene promoter appears to be associated with more severe stroke and higher in-hospital mortality in patients with acute ischemic stroke. Higher leptin levels appear to be related to favorable functional outcome.
