Abstract
INTRODUCTION: The relationship between poststroke fatigue (PSF) and serum Cystatin C (Cys-C) levels in hypertensive intracerebral hemorrhage (HICH) patients has not been determined. In this study, we investigated the association between serum Cys-C levels and PSF in HICH patients. METHODS: A total of 125 patients with HICH were enrolled. Fatigue assessment was performed 6 months after HICH onset. The presence of PSF was defined as Fatigue Severity Scale (FSS) of 4 or more. Serum Cys-C levels were measured within 24 hr after admission. The correlation between FSS score and Cys-C level was analyzed by Spearman's correlation. Receiver operating characteristic (ROC) curves for PSF were calculated using Cys-C values. RESULTS: Of enrolled 125 patients in the study, 36.0% who developed PSF were divided to the PSF group, which had higher Cys-C levels compared with the no-PSF group. There was significant positive correlation between FSS score and serum Cys-C level. Receiver operating characteristic curves for PSF revealed an area under the curve of 0.86 for Cys-C. High admission Cys-C (>0.75mg/L) yielded specificity of 93.7%, positive predictive value of 87.5%, and negative predictive value of 88.2%. In multivariate analysis, Cys-C increased by 1 mg/dl (0.1 mg/L), and the risk of PSF in patients increased by 2.55 times (odds ratio = 2.55, 95% CI: 1.65-3.95, p < .001). CONCLUSIONS: High Cys-C levels have predictive value for PSF and can be used as one screening indicator for PSF occurrence.
