Correlation of common inflammatory cytokines with cognition impairment, anxiety, and depression in acute ischemic stroke patients

Inflammatory cytokines are related to cognitive function and psychiatric disorders in patients with several diseases. However, few relevant studies have been performed on acute ischemic stroke (AIS) patients. Hence, this study aimed to investigate the correlation of common inflammatory cytokines with cognition impairment, anxiety, and depression in AIS patients. Common inflammatory cytokines of 176 AIS patients (including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, and IL-17) were measured using Human Enzyme Linked Immunosorbent Assay Kits. Cognition impairment (Mini-Mental State Examination (MMSE)), anxiety (Hospital Anxiety and Depression Scale for anxiety (HADS-A)), and depression (HADS-D) were evaluated. The incidence of cognition impairment, anxiety, and depression was 43.2, 39.2, and 31.2%, respectively. TNF-α and IL-6 were negatively associated with MMSE score, and high TNF-α, IL-1β, and IL-6 were correlated with cognition impairment occurrence. In addition, TNF-α, IL-1β, and IL-17 were positively associated with HADS-A score, while only high TNF-α was associated with anxiety occurrence. Furthermore, TNF-α, IL-1β, and IL-17 were positively associated with HADS-D score, while high IL-1β, IL-6, and IL-17 correlated with depression occurrence. Multivariate logistic regression revealed that TNF-α and National Institutes of Health Stroke Scale (NIHSS) score ≥5 were associated with high risk of cognition impairment; TNF-α, IL-17, unemployed before surgery, hypertension, and chronic kidney disease (CKD) correlated with high anxiety occurrence. Furthermore, IL-17, divorced/widowed/single status, diabetes, and NIHSS score ≥5 were associated with high risk of depression. In conclusion, common inflammatory cytokines including TNF-α, IL-1β, and IL-17 were related to cognition impairment, anxiety, or depression in AIS patients.
