Abstract

Indicators of an acute phase response (APR) in acute ischemic stroke have been shown to correlate with infarct size and predict stroke recurrence. In this study, we examined how well the APR indicators predicted long-term stroke recovery compared with standard clinical predictors of recovery. Plasma levels of interleukin-6 (IL-6), fibrinogen, white blood cells (WBCs), and serum albumin were measured within 4±2 days of onset in 131 stroke patients who were free of apparent infections. Standard clinical predictors included initial National Institutes of Health Stroke Scale (NIHSS), infarct size on computed tomography (CT), and Glasgow scale. The individual correlations with 6-month Glasgow outcome were IL-6, 0.42; fibrinogen, 0.24; WBC, 0.35; albumin, 0.47; NIHSS, 0.53; infarct size, 0.19; and initial Glasgow, 0.57. (all P<.005). Multiple regression analysis yielded an adjusted R2 of .31 for the APR indicators, compared with .38 for the clinical variables. These results indicate that the initial APR is highly correlated with 6-month stroke recovery and that this correlation approaches that observed with standard clinical predictors.
