Abstract

Background. Several studies have found that an increased concentration of haemostatic or inflammation markers was associated with worse prognosis in vascular disease. The inflammatory components in ischemic stroke are of current interest, and there is some experimental evidence that they may be linked. Hypothesis. The study was performed to determine the association between the neurological clinical outcome and levels of cell adhesion molecules in the first four days of hospitalization in patients with acute ischemic event. Methods. This prospective, pilot, case-controlled study examined the association between the clinical outcome and inflammatory markers within the first few days of hospitalization. The neurological evaluation was performed using the NIH score on admission and four days later, and levels of cell adhesion molecules were measured by ELISA methods on admission and four days later. Results. Twenty three patients with an acute cerebral event (mean age 71 ± 15 y, 12 women and 11 men) were examined neurologically on admission and four days later. Among 19 patients who improved, there was a significant decrease in the NIH neurological scale, from 3.8 ± 3.2 to 1.3 ± 1.8 (p = 0.01), which was accompanied by a significant decrease in the cell adhesion molecules that were measured (E-selectin, ICAM-1 and VCAM-1). Of the four patients who did not improve, their mean clinical NIH score was 10 ± 4.6 and worsened or remained unchanged after four days of follow-up. In this group, we could not demonstrate a significant change in levels of cell adhesion molecules between days one and four. Conclusions. Patients who improved clinically within the first four days of hospitalization demonstrated a remarkable inhibition of all three cell adhesion molecules that were measured (E-selectin, ICAM-1, and VCAM-1). Patients who did not improve had more severe cerebral infarcts, a higher NIH score on admission (10 ± 4.6), and no change was observed in levels of cell adhesion molecules during the follow-up period. Measuring cell adhesion molecule levels may predict objectively the clinical outcome in hospitalized patients with acute ischemic stroke.
