High concentrations of resistin in the peripheral blood of patients with acute basal ganglia hemorrhage are associated with poor outcome☆

Abstract 

Purpose

Resistin increases in peripheral blood of patients with intracerebral hemorrhage (ICH). We sought to evaluate its relation with disease outcome.

Materials and Methods

Thirty healthy controls and 86 patients with acute ICH were included. Plasma samples were obtained on admission. Its concentration was measured by enzyme-linked immunosorbent assay.

Results

Thirty-two patients (37.2%) died from ICH in a week. The plasma resistin level (24.2 ± 9.7 ng/mL) in patients was significantly higher than that (8.8 ± 2.4 ng/mL) in healthy controls after adjustment by age, sex, hypertension, diabetes mellitus, hyperlipidemia, and body mass index using analysis of covariate (F = 9.507, P = .003).A univariate correlation analysis found Glasgow Coma Scale (GCS) score and ICH volume, but a multivariate linear regression only selected GCS score (t = −4.587, P < .001) to be related to plasma resistin level. On a multivariate logistic regression, plasma resistin level (odds ratio = 1.257, 95% confidence interval = 1.058-1.492, P = .009) was an independent variable predicting 1-week mortality. A receiver operating characteristic curve identified that a plasma resistin level greater than 26.3 ng/mL predicted 1-week mortality of patients with 81.2% sensitivity and 81.5% specificity (P < .001). Areas under curves of GCS score and ICH volume were not statistically significantly larger than that of plasma resistin level (P > .05).

Conclusions

Increased resistin level is found after ICH, in association with a poor clinical outcome.
