ABSTRACT
Objective To investigate the effects of quetiapine on serum levels of brain-derived neurotrophic factors ( BDNF) and the correlation between BDNF and psychiatric symptoms and cognitive function in patients with first-episode schizophrenia. Methods Eighty patients with first-episode schizophrenia ( treatment group) were treated with quetiapine orally for 4 weeks,at initial dose of 100 mg·d-1 and average dose of (580±120) mg·d-1 . The psychiatric symptoms were evaluated by using the positive and negative syndrome scale ( PANSS) . The cognitive function was assessed by using Wisconsin cards sort test ( WCST) . The serum BDNF level was detected with enzyme-linked immunosorbent assay ( ELISA) . Results The serum level of BDNF was markedly lower in schizophrenic patients before[(13. 72±8. 79) ng·mL-1,P<0. 01] and after treatment[(18. 02±9.06) ng·mL-1,P<0.05]in comparison with normal controls(23. 67±10. 13) ng·mL-1]. After treatment,the PANSS total scores and subscale scores decreased,WCST number of categories and the number of correct answers increased,and the number of wrong answers reduced. There was a positive correlation between the serum BDNF and negative symptoms ( SANS) ( r= 0. 54, P=0. 032),and the number of correct answers. Conclusion The quetiapine significantly increases serum level of BDNF in schizophrenia patients,which correlates positively with improvements in symptoms and cognitive function.
