Abstract:
Objective To investigate the changes of serum IL-1β,IL-6 ,TNF-α,NGF and BDNF levels and their correlation with clinical symptoms of schizophrenia inpatiens and their value in the auxiliary diagnosis of schizophrenia .Methods The case-control study was used .The levels of serum IL-1β,IL-6 ,TNF-α,NGF and BDNF were measured by using the enzyme linked immunosorbent assay(ELISA) in 85 inpatients with schizophrenia and 85 healthy controls .Their changes in the case group were compared between before treatment and after 3-month treatment .The Pearson correlation analysis was used to analyze the correlation between the lev-els of IL-1β,IL-6 ,TNF-α,NGF and BDNF with the positive and negative syndrome scale (PANSS) score and the auxiliary diagnosis value of serum cytokine and neurotrophic factor levels were evaluated with the receiver operating characteristic (ROC) curve .Re-sults The levels of serum IL-1β(t=4 .560) ,IL-6(t= 4 .957) and TNF-α(t= 4 .799) before treatment in the schizophrenia case group were significantly higher than those in control group ,while the NGF(t= -4 .806) and BDNF(t= -4 .881) levels were sig-nificantly lower than those in the control group ,the differences were statistically significant (P<0 .01) .After 3-month treatment , the levels of serum IL-1β(t=4 .543) ,IL-6(t=4 .327) and TNF-α(t=4 .654) in the schizophrenia case group were significantly de-creased compared with before treatment ,while the NGF(t= -4 .641) and BDNF(t= -4 .876) levels were significantly increased , the differences were statistically significant (P< 0 .01) .IL-1β was positively correlated with the positive symptoms scores (r=0 .325 ,P<0 .01) ,IL-6 was positively correlated with the negative symptoms scores (r=0 .319 ,P<0 .01) ,TNF-α was positively correlated with the positive symptoms scores (r= 0 .281 ,P< 0 .01) ,NGF was negatively correlated with the positive symptoms scores(r= -0 .229 ,P<0 .05) ,BDNF was negatively correlated with the positive symptoms scores (r= -0 .272 ,P< 0 .05) .The cut-off values of serum IL-1β,IL-6 ,TNF-α,NGF and BDNF in the auxiliary diagnosis of schizophrenia were 40 .083 ,20 .037 ,17 .115 ,19 .998 ,584 .157pg/mL respectively ,the corresponding areas under the ROC were 0 .723 ,0 .772 ,0 .686 ,0 .712 and 0 .708 respectively ,the sensitivities were 0 .565 ,0 .871 ,0 .894 ,0 .859 and 0 .729 respectively ,and the specificities were 0 .871 ,0 .565 ,0 . 365 ,0 .494 and 0 .624 respectively .Conclusion The levels of serum IL-1 ,IL-6 ,TNF-α,NGF and BDNF have the correlation with the clinical symptoms of schizophrenic inpatients and have a certain value in the auxiliary diagnosis of schizophrenia .
