大隐静脉曲张光凝治疗后血清IL-2和sIL-2R的测定

目的 :测定大隐静脉曲张血管内光凝治疗前后血清中白细胞介素 - 2 (sIL - 2R)及其可溶性受体(sIL - 2R)的变化。方法 :5 0例大隐静脉曲张患者根据症状分为轻、重两组 ,取静脉血液 ,分别采用放射免疫分析和双抗体夹心间接ELISA法检测血清中IL - 2和sIL - 2R水平。另外取 30例正常成人血清作为对照。结果 :大隐静脉曲张患者轻症组患者血清中IL - 2和sIL - 2R较正常水平没有明显改变 ;随着病情的加重 ,IL - 2水平明显降低 ,sIL - 2R水平明显升高。治疗后两组IL - 2先下降 ,后逐渐升高 ;sIL - 2R水平先升高 ,后下降。轻症组IL - 2和sIL - 2R稳定水平接近术前 ;而重症组IL - 2稳定后水平高于治疗前 ,sIL - 2R稳定水平低于治疗前水平。结论 :IL - 2和sIL - 2R水平测定可了解静脉曲张患者免疫功能状态 ,判定治疗后病情恢复情况。

Changes of Serum IL-2 and sIL-2R Levels after Intravenous Photo-coagulation in Patients with Varicose Greater Saphenous Vein

Objective To determine the changes of serum interleukin 2 (IL-2) and soluble interleukin 2 receptor (sIL-2R) levels in patients with varicose greater saphenous vein after intravenous photocoagulation. Methods Fifty patients with varicose greater saphenous voin were divided into two groups (mild and severe) according to their clinical symptoms. Serum IL-2 and sIL-2R levels were determined with RIA and ELISA respectively in these patients and 30 controls. Results Serum levels of IL-2 and sIL-2R in patients of the mild group were about the same as those in the controls. In patients of the severe group, levels of IL-2 decrased and levels of sIL-2R increased significantly. After photocoagulation, the IL-2 levels dropped at first but gradually rose; the reverse was true for the sIL-2R levels. The final levels of IL-2 and sIL-2R approched those before treatment in te mild group. In the severe group, the final IL-2 levels were higher and sIL-2R levels lower than those before photocoagulation. Conclusion Determination of serum IL-2 and sIL-2R levels revealed information about the immune status of the patients and could be applied for judgement of the treatment effect.
