title: Relationship between C-reactive protein and early activation of leukocytes indicated by leukocyte antisedimentation rate (LAR) in patients with acute cerebrovascular events.
abstract: The purpose of this study was to determine the relationship between high-sensitive C-reactive protein (hsCRP) and leukocyte antisedimentation rate (LAR) as a specific test to detect early activation of leukocytes providing the first line of defence against infections in ischemic stroke. In 49 patients with acute ischemic events and 61 healthy subjects (HS), we examined LAR, astroglia specific S100B indicating the extent of brain tissue damage and hsCRP within 6 hours, as well as 24 and 72 hours after onset of symptoms. Serum levels of hsCRP on admission was significantly higher in patients with acute ischemic stroke (AIS) compared to HS and were higher in patients with recurrent to first ever ischemic stroke. Increased basal levels of hsCRP also correlated with severity of stroke and extent of infarct reflected by S100B levels in sera, but did not correlate with post-stroke infections. However, a higher rate of infection was observed among patients, in whom hsCRP was elevated at 72 hours but LAR did not increase. Therefore, such late elevation of hsCRP may indicate pre-clinical infections due to deficient leukocyte activation. Simple tests like LAR and hsCRP may help in predicting outcome and high risk of infectious complications.
