| description | Abstract Background Stroke has become a leading cause of death and disability worldwide, and despite the introduction of new screening programs, therapies, and monitoring technologies, there is still a need to develop more useful biochemical tests to monitor treatment response and inform clinical decision-making. Cell-free DNA released from damaged neurons in stroke patients may be useful in assessing stroke prognosis. The purpose of this study was to evaluate the role of cell-free DNA and a highly sensitive blood biomarker in acute ischemic stroke. 188 patients with acute ischemic stroke were recruited for the study. The level of cell-free DNA in plasma was estimated using a real-time PCR assay for the β-globin gene (Qiagen-Rotor-Gene Q MDX, Germany). Clinical assessment was performed with the National Institutes of Health Stroke Scale (NIHSS) at the time of admission. After a period of three months from the onset of stroke, (mRS) scores were estimated using the modified Rankin scale. Results Elevated levels of cell-free DNA were found in patients with higher NIHSS admission scores and mRS 3-month scores (p < 0.05). The regression analysis revealed that the markers are associated with an unfavorable outcome in comparison to other stroke risk factors (R 2 = 0.224). Stroke outcome was relatively better in patients with a cell-free DNA level < 10,000 kilogenome equivalents/L (p < 0.05). Conclusions Measurement of total cell-free DNA levels is a simpler and less-expensive biomarker suggesting potential clinical application of blood-based test. Cell-free DNA can contribute to the clinical evaluation and optimal management of ischemic stroke patients. This biomarker seems to have the potential to predict the long-term prognosis of acute ischemic stroke. |
