The role of inflammatory cytokines in patients with depression in Parkinson's disease / 实用医学杂志

ABSTRACT

Objective To compare the serum levels of interleukin(IL)-6,IL-18 and tumor necrosis factor alpha(TNF-α)in patients with DPD,PD,depression disorder and healthy controls and to analyze the correlations of serum inflammatory factors in DPD patients. Methods Serum levels of IL-6,IL-18 and TNF-αwere measured using enzyme linked immunosorbent assay(ELISA) kits. Several scales were performedin DPD patients. Results DPD,PD and depression disorder patients had significant lower baseline levels of IL-6 and TNF-αwhen compared to healthy controls(P < 0.05). The levels of IL-6 and TNF-α in DPD patients were significantly increased after 4 weeks of anti-depression treatment(P < 0.05). No difference of cytokines levels in gender and in severity of DPD patients was detected Serum levels of these inflammatory cytokines were not significantly correlated with the UP-DRS Ⅲ,H & Y,MMSE and HAMD scores in DPD patients. Conclusions Serum inflammatory factors(IL-6, TNF-α)were altered in patients with DPD in the earlier course of disease. However ,the role of IL-18 remained unknownin the occurrence of DPD disease.
