NERVE GROWTH FACTOR AND S100B IN BLOOD AND CEREBROSPINAL FLUID AS INDICATORS OF THE SEVERITY OF ISCHEMIC STROKE

Abstract

Aim. To determine the relationship between the content of nerve growth factor (NGF) and S100b with the clinical manifestations of acute ischemic stroke (IS). Material and methods. A total of 17 patients with IS, age 68.5 (67; 78.5) years were examined; comparison group: 15 volunteers, age 65.0 (62.0; 66.5) years. The patients’ condition was assessed by the size of the brain lesion, the NIHSS and mRS, somatic status. Serum and cerebrospinal fluid (CSF) NGF, S100b, IL6, plasma D-dimer (ELISA) were determined at 1, 3, 10 days after IS. Results. We found NGF decreased in a serum of patients IS with a fatal outcome in 1-10 days. The dependency of serum (r = -0.300, p < 0.05) and CSF (r = -0.271, p < 0.05) NGF with the size of the lesion and patients somatic status (r = -0.322, p < 0.05) was discovered. The concentration of S100b increased from 3 days in deceased patients in the CSF and blood. The S100b correlated with the outcome of the disease (r = 0.650, p < 0.01), NIHSS (r = 0.651, p < 0.01), mRS (r = 0.451, p < 0.05). NGF and S100b levels were associated with the increasing of plasma D-dimer and CSF IL-6. Thus the NGF and S100b reflect the brain damage severity and the patients’ condition in the acute IS and associates with inflammation activity.
