目的探讨首发广泛性焦虑障碍患者外周血炎性细胞因子与焦虑症状的相关性。
方法运用夹心法酶联免疫吸附法(ELISA)技术测定48名首发广泛性焦虑障碍患者与48名对照组被试外周血IL-1、 IL-2、 IL-4、 IL-5、 IL-6、 IL-8、IL-10、 IL-12p70、GM-CSF、 IFN-γ水平,运用免疫透射比浊法测定C-反应蛋白(CRP)的血浓度,并应用广泛性焦虑障碍量表(GAD-7)、状态-特质焦虑问卷(STAI)评定其总体焦虑程度和特质焦虑、状态焦虑水平。
结果首发广泛性焦虑障碍组CRP[(1.19±0.80)mg/L vs (0.68±0.70)mg/L, t=3.31]、IL-1α[(70.34±3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50]、IL-2[(7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85]、IL-4[(102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29]、IL-6[(12.55±2.37)pg/ml vs (2.71±1.35)pg/ml, t=14.79]、IL-8[(44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10]、IL-12[(18.16±24.17)pg/ml vs (10.82±4.72)pg/ml, t=2.06]、IFN-γ[(23.32±15.52) vs (16.48±6.80)pg/ml, t=2.79]、GM-CSF[(19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80]等炎性细胞因子水平显著高于正常对照组(均 P<0.05);状态焦虑SAI、特质焦虑TAI与IL-1α、IL-2、IL-6、IL-8、IL-12、IFN-γ、GM-CSF均呈显著正相关,相关系数 r为0.24~0.76。
结论首发广泛性焦虑障碍患者外周血多个炎性细胞因子升高,并和总体焦虑程度、状态焦虑及特质焦虑水平呈正相关,提示其可能存在免疫功能异常。
ObjectiveTo investigate the relationship between peripheral inflammatory cytokines and anxiety symptoms in patients with the first-episode generalized anxiety disorder.
Methods48 patients diagnosed with the first-episode generalized anxiety disorder according to ICD-10 criteria and 48 healthy subjects were recruited.Peripheral levels of IL-1, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, GM-CSF and IFN-γ of both groups were evaluated by enzyme-linked immunosorbent assay (ELISA), and CRP was evaluated by immunoturbidimetric method. Generalized Anxiety Disorder Scale(GAD-7) and State-Trait Anxiety Inventory(STAI)were used to assess the levels of overall anxiety, state anxiety and trait anxiety.
ResultsThe levels of CRP((1.19±0.80)mg/L vs (0.68±0.70)mg/L, t=3.31), IL-1α((70.34±3.60)pg/ml vs (16.94±3.42)pg/ml, t=74.50), IL-2((7.25±3.42)pg/ml vs (4.95±2.31)pg/ml, t=3.85), IL-4((102.02±73.14)pg/ml vs (75.55±32.78)pg/ml, t=2.29), IL-6((12.55±2.37)pg/ml vs (2.71±1.35)pg/ml, t=14.79), IL-8((44.64±16.21)pg/ml vs (35.69±11.70)pg/ml, t=3.10), IL-12((18.16±24.17)pg/ml vs (10.82±4.72)pg/ml, t=2.06), IFN-γ((23.32±15.52)pg/ml vs (16.48±6.80)pg/ml, t=2.79), GM-CSF((19.07±11.12)pg/ml vs (13.40±8.54)pg/ml, t=2.80) in patients with the first-episode generalized anxiety disorder were significantly higher than normal controls( P<0.05). Both SAI and TAI had significantly positive correlation with the levels of IL-1α, IL-2, IL-6, IL-8, IL-12, IFN-γ and GM-CSF( r=0.24-0.76, P<0.05).
ConclusionThe levels of some peripheral inflammatory cytokines in patients with the first-episode generalized anxiety disorder are significantly increased, and they have positive correlation with general anxiety, state anxiety and trait anxiety, which may suggest some immune system defects in the patients.
