Indoleamine 2,3-dioxygenas in the prediction of post-stroke cognitive impairment
Journal Title: Chinese Journal of Clinical Research - Year 2024, Vol 37, Issue 4
Abstract
"<b>Objective</b> To investigate the correlation between cerebral hemodynamics, serum indoleamine 2,3-dioxygenase (IDO) and post-stroke cognitive impairment (PSCI), and to explore the predictive value of IOD for PSCI. <b>Methods</b> A total of 50 patients with acute ischemic stroke who were diagnosed and the onset being not more than 7 days in the Department of Neurology of the 900th Hospital of PLA Joint logistics Support Force from July 2020 to June 2021 were selected as the case group. According to the presence or absence of PSCI, the patients were divided into PSCI group (n=30) and non-PSCI (PSNCI) group (n=20), and 50 healthy individuals during the same period were selected as the control group (n=50). ELISA was used to detect the serum IDO levels of the enrolled population. Transcranial color Doppler ultrasound (TCCD) breath-holding test was performed and relevant data was recorded, breath holding index (BHI) was calculated as an evaluation index of cerebral hemodynamics. ROC curve was used to analyze the predictive efficacy of IDO level on PSCI. <b>Results</b> There were statistically significant differences in serum levels of D-dimer and N-terminal pro-brain natriuretic peptide (NT-proBNP) among the three groups (P＜0.05). The serum IDO levels in the control group, PSNCI group, and PSCI group were (0.23±0.05), (0.25±0.02), and (0.31±0.03) ng/mL, respectively, with statistically significant differences among the three groups (F=41.092, P＜0.01). Compared with the PSNCI group, the PSCI group showed an increase in IDO levels (P＜0.05), while there was no statistically significant difference in D-dimer and NT-proBNP levels (P＞0.05). There was no significant difference in BHI among the three groups (P＞0.05). No significant difference was found in lesion location between the PSCI group and the PSNCI group (χ<sup>2</sup>=15.478, P=0.113). The predictive efficacy was highest when the IDO level cutoff value was 0.277 ng/mL, with a area under the ROC curve (AUC) of 0.938, sensitivity of 83.3%, and specificity of 95.0%. <b>Conclusion</b> There is a significant correlation between serum IDO levels and PSCI, but the relationship between hemodynamic indicators and the occurrence of PSCI is still unclear. Early detection of IDO levels after acute ischemic stroke is helpful for the early identification and diagnosis of PSCI."
