Title
Biochemical markers for blood-brain barrier dysfunction in acute ischemic stroke correlate with evolution and outcome
Author
Abstract
Background/Aims: We evaluated the cerebrospinal fluid/serum albumin ratio (AR) and kinetics of matrix metalloproteinase-9 (MMP-9) in blood as markers for blood-brain barrier (BBB) disruption after acute ischemic stroke. Methods: The AR was determined in 88 patients with acute ischemic stroke or transient ischemic attack. MMP-9 was measured on admission, 24, 72 h and 7 days after stroke onset. Results: The AR was related to stroke severity, the occurrence of stroke progression and the modified Rankin Scale score at month 3. MMP-9 levels on admission were significantly elevated compared to controls and dropped in the first 72 h after stroke, except in patients with stroke progression and larger infarcts in the subacute phase. Conclusions:We demonstrate that the extent of BBB breakdown in hyperacute stroke relates to initial stroke severity, stroke evolution and long-term outcome. The kinetics of MMP-9 confirm its pivotal role in secondary brain damage after ischemic stroke.
