Relationship between depression and inflammatory factors and brain-derived neurotrophic factor in patients with perimenopause syndrome

摘要

The relationship of depression with levels of serum inflammatory factors and brain-derived neurotrophic factor (BDNF) in patients with perimenopausal syndrome was analyzed to investigate the predictive values of risk factors for depression in patients with perimenopausal syndrome. A total of 73 patients with perimenopausal syndrome were selected, and divided into the depression (n=30) and non-depression (n=43) groups. Results showed that the self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores in the depression group were significantly higher than those in the non-depression group (P<0.05). The serum BDNF level in the depression group was significantly lower than that in the non-depression group (P<0.05). The levels of serum inflammatory factors, including C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), in depression group were obviously higher than those in non-depression group (P<0.05). The correlation analyses of serum inflammatory factor and BDNF levels with depression showed that CRP and TNF-α were positively correlated with SDS score, while BDNF level was negatively correlated with SDS score. Logistic regression analyses revealed that menstrual status, chronic diseases, serum inflammatory factors (CRP, IL-6 and TNF-α) and BDNF levels had independent predictive values for depression in patients with perimenopausal syndrome (P<0.05). In conclusion, levels of serum CRP, IL-6, TNF-α and BDNF can be used as judgment indicators for the severity of depression.
