Abstract:
Objective:To explore the relationship between serum cytokine levels and cognitive impairment in patients with bipolar I manic episode.Methods:Forty-four patients with bipolar I manic episode (BDI group) and 42 healthy volunteers (HC group) matched with demographic data were included.Peripheral serum interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-23 (IL-23), and tumor necrosis factor-α (TNF-α) levels were detected by enzyme-linked immunosorbent assay (ELISA). The repeatable battery for the assessment of neuropsychological status (RSPM) was used to evaluate the cognitive function of the two groups.Young manic rating scale (YMRS) was used to evaluate the clinical manic symptoms of patients.Hypothesis testing and correlation analysis were processed by SPSS 22.0.Results:(1) The expression levels of serum cytokines IL-6, IL-10, IL-23 and TNF-α in BDI group ((38.872±7.803), (33.259±7.260), 42.350(33.600, 55.390), (108.309±19.398)) were significantly different with those in HC group ((24.664±6.083), (29.257±5.208), 17.360(12.870, 30.690), (68.674±13.610)), and the differences were statistically significant (( t=9.387, t=2.947, Z=-5.477, t=10.921, all P<0.01)). (2) In the RBANS cognitive test, the visual span, attention, delayed memory and total scale scores of the BP group ((92.909±16.126). (83.091±8.529), (80.636±9.592), (416.318±33.438)) were significantly different with those of the HC group ((82.905±10.958), (92.381±14.850), (93.714±7.613), (436.905±37.228), t=3.378, t=-3.538, t=-6.982, t=-2.700, all P<0.05). (3)Correlation analysis showed that in the BDI group, the course of disease was positively correlated with IL-6 and IL-23( r=0.509, r=0.298, P<0.05), the visual breadth was positively correlated with IL-10 and TNF-α ( r=0.426, r=0.647, P<0.05), language was negatively correlated with IL-23 level ( r=-0.372, P<0.05), attention was significantly negatively correlated with IL-6, IL-10, and TNF-α ( r=-0.315, r=-0.318, r=-0.498, all P<0.05), delayed memory was positively correlated with IL-10 and TNF-α ( r=-0.360, r=-0.621, P<0.05). No significant correlation was found between YRMS score, immediate memory score and cytokines ( P>0.05). Conclusion:Patients with bipolar I disorder manic have changes in serum levels of cytokines and cognitive dysfunction. The course of disease and cognitive function are related with serum cytokine level.
