INTRODUCTION: This study aimed to explore the potential association between oxidative stress markers and Moyamoya Disease (MMD), a complex cerebrovascular disorder characterized by vascular constriction and collateral vessel formation. The study focused on thiol-disulfide homeostasis and ischemia-modified albumin (IMA) levels as indicators of oxidative stress.
METHODS: A total of 23 MMD patients and 23 control subjects were included in the study. Clinical assessments and comprehensive blood analyses were conducted to evaluate factors including age, gender, disease duration, treatment history, and biochemical parameters. Thiol-disulfide homeostasis parameters were measured using an automated method. Ischemia-modified albumin levels were also analyzed. Statistical analyses, including chi-square tests and ROC curve analysis, were performed to determine differences and potential diagnostic cut-off points.
RESULTS: Elevated levels of native thiol, total thiol, and disulfide were observed in the MMD patient group compared to the control group, statistical significant. Ischemia-modified albumin levels were notably higher in the patient group, corroborating the association between oxidative stress and ischemic events. ROC curve analysis identified potential diagnostic cut-off points for these markers. The study also highlighted clinical differences, including BMI, CRP levels, and the frequency of various symptoms, between the patient and control groups.
DISCUSSION AND CONCLUSION: Our study offers insights into the intricate interplay between oxidative stress and Moyamoya Disease. The statistically significant elevated levels of thiol-disulfide markers and ischemia-modified albumin suggest potential links to oxidative stress dynamics within MMD. These findings contribute to our understanding of oxidative stress in cerebrovascular diseases and open avenues for further research.
