Purpose: This study aimed to assess the relationship between S100Î² protein with neurological
deficit and mortality within 1 week in patients with Intracerebral hemorrhage (ICH) stroke. And
also, to determine the relationship between hematoma volume with S100Î² protein.
Patients and Methods: a prospective observational cohort study. Patients with sampling from
consecutive admission from August 2016 to December 2017 were performed head CT Scan, met
inclusion and exclusion criteria. Neurological deficits as ascertained with National Institute of
Health Stroke Scale (NIHSS). Blood samples were taken at the admission to the hospital and on the
7th day of onset.
Results: There were 46 patients with 25 men (54.3%) and 42 controls with a median age of 56 (31-
76) and 34.5 (21-67) years. The most risk factor was hypertension (78,3%). Median onset of acute
ICH stroke was 8.5 (0.5-48) hours. Median level of consciousness according to Glasgow Coma
Scale (GCS) at the admission to the hospital was 14 (3-15) and the NIHSS was 11.50 (0-37). Serum
S100Î² protein levels correlated significantly with NIHSS (r=0.418;p=0.004). Area Under Curve
(AUC) of S100Î² was 0.839Â±0.103 (95% CI, 0.638-1.000), cutoff level was 28,505 pg/mL with 80%
sensitivity and 87.8% specificity (p=0.014). Serum S100Î² protein levels associated significantly
with mortality within 1 week (p=0.032). The hematoma volume correlated with S100Î² protein
Conclusion: S100Î² protein was significant correlation with neurological deficits. S100Î² protein
was associated significantly with mortality within 1 week. The hematoma volume was significant
correlation with S100Î² protein.
