Introduction: Brain blood flow disruption in ischemic stroke will trigger cells damage cascade and caused infarction. Interleukin-6 (IL-6) and neuron specific enolase (NSE) are brain cells damage marker that can be markers of acute ischemic stroke outcome.

Aim: To investigate the effect of IL-6 and NSE levels on acute ischemic stroke outcome and its interacting factors.

Methods: An observational cohort study on ischemic stroke patients with onset ≤3 days in several hospitals in Jakarta and Depok in 2014. Medical history and physical examination were carried out as well as laboratory parameters; hematocrit, fibrinogen, low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride, IL-6, and NSE. The National Institute of Health Stroke Scale (NIHSS) were assessed ≤72 hours of onset and 7 days along with Modified Rankin Scale (mRS) at 1 month of onset. Bivariate and multivariate logistic regression were done to investigate the association of IL-6 and NSE with stroke outcome and other factors.

Results: One-hundred thirty-five subjects were included, mostly male (62%), with age mean 59,4±10,7 years and subtype PACS (76%). Interleukin-6 and NSE level were elevated in 61,5% and 21,5% subjects. Interleukin-6 and fibrinogen influenced the mRS, while diabetes and fibrinogen influenced the NIHSS. NSE serum didn’t show any association with mRS nor NIHSS, but influenced by dyslipidemia.

Discussion: There was a tendency of worse outcome on high IL-6 level patients, although by multivariate analysis IL-2 alone was not sufficient enough as prognostic marker in acute ischemic stroke outcome. Neuron specific enolase serum didn’t show any association with acute stroke outcome due to also influenced by sex, smoking, and fibrinogen levels.
