Abstract:
Objective To explore the changes in serum pro-inflammatory cytokine factor and their relationship with memory function in patients with chronic insomnia comorbid and depression(ICD).Methods A total of 40 ICD patients and 41 chronic insomnia disorder(CID)patients were recruited at the Clinic of Sleep Disorder,and concurrently 41 healthy individuals as controls(CON)were recruited during the same period.The Pittsburgh sleep quality index(PSQI)and 17-item Hamilton depression rating scale(HAMD-17)were used to assess the severity of insomnia and depression in the subjects,and the nine box maze was used to evaluate their memory function.Enzyme linked immunosorbent assay was used to detect the levels of serum tumor necrosis factor(TNF)-α,TNF-β,interleukin(IL)-1β,IL-6,and serum amyloid A(SAA),and the correlation between pro-inflammatory cytokine factor levels and cognitive function was analyzed.Results The HAMD and PSQI scores were significantly higher in ICD and CID groups than in CON[HAMD:19.0(14.0,22.0)vs.10.0(7.5,12.5)vs.2.0(1.0,4.0);PSQI:17(15,19)vs.15(13,16)vs.2(0,3);P<0.01]which was also higher in ICD group than in CID group(P<0.01).The number of errors in spatial reference memory(SRM)and spatial working memory(SWM)were higher in the ICD and CID groups than in CON[SRM:2.5(1.0,4.0),vs.1.0(0,3.0)vs.0(0,1.0);SWM:5.00(4.00,7.75)vs.4.00(2.00,5.00)vs.1.00(1.00,2.50);P<0.01].The number of errors were also higher in SRM and SWM in ICD group than in CID group(P<0.01).The serum levels of TNF-α,TNF-β,IL-1β,IL-6,and SAA were higher in ICD and CID groups than in CON(P<0.01),and the serum levels of TNF-β and IL-6 were also higher in ICD group than in the CID group(P<0.01).In the ICD group,the partial correlation analysis showed that TNF-α(r=0.394,P=0.021)and IL-1β(r=0.398,P=0.020)were positively correlated with the number of SRW errors,while TNF-β(r=0.381,P=0.026)and SAA(r=0.446,P=0.008)were positively correlated with the number of SWM errors.TNF-β were also positively correlated with the number of recognition memory errors(r=0.347,P=0.044).Conclusion ICD patients have memory impairment,which may relate to increased levels of pro-inflammatory cytokine factor in their serum.
