    -OBJECTIVE: Strokes are among the leading causes of death worldwide and have different characteristics. Different physiopathological mechanisms characterize the -umerous subtypes of ischemic stroke (IS). In this study, we investigated the relationship between serum levels of autophagy-5 protein, apolipoprotein B-48, and oxidative stress markers in patients with ischemic stroke.-METHODS: For this study, 100 participants were recruited, of which 50 were patients with IS and 50 were healthy individuals. We conducted a case-control study at Imam Reza Hospital from March 2019 to April 2020. Serum levels of ATG5, apo B-48, and oxidative stress markers were determined in both groups. Our Receiver Operating Characteristic Analysis evaluated the additional diagnostic value of these factors in both groups. -RESULTS: Diabetes, smoking, age, sex, alcohol con-sumption, weight, and height did not differ significantly between the 2 groups (P > 0.05). However, the 2 groups had significant differences in hypertension and body mass in-dex (P < 0.05). Fifty-four percent (27 patients) of patients with IS had an ischemic stroke in large vessels, while 46% (23 patients) had an ischemic stroke in small vessels. Serum levels of ATG5, apo B-48, and oxidative stress markers were higher in the case group than in the control group (P< 0.0001).-CONCLUSIONS: In patients with IS, serum levels of ATG5, apoB-48, malonaldehyde, total oxidative stress, and total antioxidant capacity can be used as novel biomarkers to predict or treat the disease.
