摘要: 目的 探讨华支睾吸虫病患者细胞因子水平与肝功能的关系。 方法  47例确诊、但未经药物治疗的华支睾吸虫病患者 ,参照Child Pugh肝功能分级法 ,按照评分将其分成A ( 3~ 4分 ) 2 0例、B( 5~ 6分 ) 15例、C( 7~ 9分 )12例等 3组。用放射免疫法及双抗体夹心酶联免疫吸附测定 (ELISA)法 ,检测血清白细胞介素 2 (IL-2 )、可溶性白细胞介素 2受体 (sIL-2R )、白细胞介素 8(IL-8)、肿瘤坏死因子α(TNF-α) ;用全自动生化分析仪检测患者血清总胆红素(TBL)、血清白蛋白 (ALB)、丙氨酸氨基转移酶 (ALT)。并进行统计分析。 结果 华支睾吸虫病患者sIL-2R、IL-8、TNF-α水平明显高于健康人对照组 (P <0.0 5 ,P <0.0 5 ,P <0.0 1) ,而IL 2含量明显减少 (P <0.0 1)。随着患者肝功能受累程度的加重 ,sIL-2R、IL-8、TNF-α含量依次递增 ,IL-2含量依次递减 ,A组和C组间差异具有显著性意义 (P <0.0 5 )。sIL-2R、TNF α含量与其TBL(r =0.3 3 1 P <0.0 5 ,r =0.5 18 P <0.0 1)及ALT (r =0.475 P <0.0 1,r =0.2 85 P <0.0 5 )呈正相关 ,与ALB呈负相关 (r =-0.3 19 P <0.0 5 ,r =-0.665 P <0.0 1)。 结论 华支睾吸虫病患者细胞免疫功能降低 ,血清IL-2、sIL-2R、TNF-α水平与肝功能状态有一定关系。

Abstract: Objective To explore the relationship between cytokine level and liver function among patients infected with Clonorchis sinensis. Methods 47 patients were divided into three groups according to the degree of Child-Pugh liver function grade: 20 in group A (3-4 scores), 15 in group B (5-6 scores) and 12 in group C (7-9 scores). Interleukin 2 (IL-2), soluble IL-2 receptor (sIL-2R), interleukin 8 (IL-8) and tumor necrosis factor (TNF-α) were examined by radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA). Automatic biochemical analyzer was employed for the determination of serum level of total bilirubin(TBL), albumin(ALB) and alanine aminotransferase(ALT). Data were analyzed with SAS statistic software. Results Serum levels of sIL-2R, IL-8 and TNF-α from patients were significantly higher than those obtained from healthy people (P<0.05, P<0.05, P<0.01), whereas the IL-2 level was significantly lower than the former (P<0.01). With the affected degree of the liver, serum levels of sIL-2R, IL-8 and TNF-α increased, in contrast to the decrease of IL-2 level. The differences were significant between groups A and C (P<0.05). The level of sIL-2R and TNF-α directly correlated with that of TBL(r=0.331 P<0.05, r=0.518 P<0.01) and ALT(r=0.475 P<0.01, r=0.285 P<0.05) respectively, but inversely correlated with the level of ALB (r=-0^319 P<0.05, r=-0.665 P<0.01). Conclusion The infection of Clonorchis sinensis results in the reduction of cellular immune function of the patients. Certain relationship exists between serum cytokine level and liver function. Two cytokines, sIL-2R and TNF-α, are involved in the process of pathology.
