Dynamic changes and its clinical significance of serum glial fibrillary acidic protein content in patients with acute cerebral infarction / 临床神经病学杂志

ABSTRACT

Objective To investigate the dynamic changes and its clinical significance of serum glial fibrillary acidic protein (GFAP) content in patients with acute cerebral infarction.Methods We consecutively collected 47 cases of acute cerebral infarction. The serum specimens were gathered on admission, at 3rd and 5th day after onset. The serum levels of GFAP were compared according to Oxford community stroke project (OCSP) and CT classifications, and the relationships between serum GFAP levels and patient's condition and prognosis of disease were analyzed. Results Serum GFAP level in TACI group was significantly higher than those in control group and other 3 subtype groups within 48 h of onset, and continuously increased at 3rd day and 5th day. The GFAP level in PACI group reached peak at 3rd day and returned nearly to normal level at 5th day. There was no significant difference between POCI group and LACI group and control group. Serum levels of GFAP were significantly higher in large infarcts and in corticosubcortical infarcts. GFAP level was related with score of NIHSS (r=0.410, P
