摘要
目的研究梗阻性黄疸免疫功能及其与内毒素血症的相关性.方法检测28例梗阻性黄疸患者及20例健康对照者血清内毒素,T淋巴细胞亚群及血清SIL2R的水平.结果梗阻性黄疸患者血清内毒素和SIL2R水平较对照组明显升高(470ng/L±113ng/L和725kU/L±201kU/Lvs284ng/L±103ng/L和324kU/L±116kU/L,P<001),T淋巴细胞亚群CD3,CD4,CD4/CD8明显降低(504%±33%和299%±38%vs638%±44%和383%±28%,P<001;122±032vs143±037,P<005),同时亦发现梗阻性黄疸内毒素血症组较非内毒素血症组CD3,CD4水平明显减低,SIL2R水平明显升高(474%±51%和276%±52%和867kU/L±231kU/Lvs523%±52%和312%±43%和674kU/L±189kU/L,P<005).相关分析显示血清内毒素水平与血清SIL2R水平呈显著正相关(r=08517,P<001).结论梗阻性黄疸时内毒素血症与免疫功能状态密切相关.
AIM To investigate the relationship between endotoxemia and cellular immunity in patients with obstructive jaundice. METHODS Serum endotoxin levels, Tlymphocyte subsets, and serum soluble interleukin 2 receptor (SIL 2R) were studied in 28 patients with obstructive jaundice and 20 controls. RESULTS The serum endotoxin levels and SIL 2R were significantly higher ( 47 0ng/L ± 11 3ng/L and 725kU/L ± 201kU/L vs 28 4ng/L ± 10 3ng/L and 324kU/L ± 116kU/L , P <0 01) and CD3 , CD4 , CD4/CD8 were much lower (50 4%±3 3% and 29 9%±3 8% vs 63 8%±4 4% and 38 3%±2 8%, P <0 01; 1 22±0 32 vs 1 43±0 37, P <0 05) than those of controls. CD3 , CD4 and SIL 2R in endoto xemia group with obstructive jaundice were significantly diferent from the non endotoxemia group (47 4%±5 1% and 27 6%±5 2% and 867kU/L ± 231kU/L vs 52 3%±5 2% and 31 2%±4 3% and 674kU/L ± 189kU/L , P <0 05). Serum endoto xin levels were positively correlatied with SIL 2R ( r =0 8517, P <0 01). CONCLUSION Endotoxemia is closely related to the status of cellular immunity in patients with obstructive jaundice.
