Evaluation of Serum Concentrations of ATG5, ApoB48 in Patients with Ischemic Stroke

Abstract

Background & objectives: Stroke is one of the most common causes of death worldwide and has distinctive features. Moreover, the different types of strokes are characterized by different physiopathological mechanisms. In the present study, we aimed to investigate the serum levels of ATG5 and apo B-48 and their diagnostic value in patients with ischemic stroke. Methods: We selected 100 participants, including 50 ischemic stroke patients (22 women and 28 men) as the case group and 50 healthy individuals (23 women and 27 men) as the control group. Then, we conducted a case-control study in Imam Reza Hospital (Tabriz, Iran) from March 2016 to April 2016. Serum levels of ATG 5 and Apo B-48 were measured in both groups. We also evaluated the additional diagnostic value of these factors in both groups using receptor-related power analysis (ROC). Results: The mean serum levels of ATG 5 and apo B-48 were significantly higher in the case group than in the control group ( p <0.0001). The values under the ROC curve (AUC) for ATG5 and apo B-48 were 0.96 and 0.91, respectively. The area under the ROC curve indicates that ATG 5 and apo B 48 are appropriate biomarkers for diagnosing ischemic stroke. Conclusion: Serum levels of ATG 5 and apo B -48 are significantly higher in patients with ischemic stroke than in healthy individuals and may be considered diagnostic biomarkers in patients with ischemic stroke.
