IL-11治疗慢性特发性血小板减少性紫癜的疗效观察

为了探讨慢性特发性血小板减少性紫癜（CITP）患者血清IL-11水平的动态变化及意义，研究重组人白细胞介素-11（rhIL-11）对CITP的治疗作用，采用ELISA方法对CITP患者治疗前后血清IL-11含量进行动态测定，并将rhIL-11应用于CITP患者，剂量1．5mg，皮下注射，每天1次，1疗程14天，治疗1—2疗程。结果表明：CITP患者血清IL-11水平明显高于正常对照组，且血清IL-11水平与CITP惠者血小板数呈平行性升高；患者经2个疗程rhIL-11治疗后，血小板数均有不同程度的升高。结论：CITP患者血清IL-11水平与患者的血小板数有一定的相关性．且rhIL-11对CITP有较好的治疗效果。

Curative Effect of Interleukin 11 on Chronic Idiopathic Thrombocytopenic Purpura

The aim of this study was to investigate the circulating levels of IL-11 in the patients with chronic idiopathic thrombocytopenic purpura (CITP), and its significance, and to evaluate the curative effect of rhIL-11 on CITP. The level of IL-11 in patients with CITP was determined by ELISA before and after treatment, respectively. 1.5 mg of rhIL-11 were injected subcutaneously, once a day, continuously for 14 days as one course, treatment time 1-2 courses as total. The results showed that the higher blood IL-11 level was found in CITP patients than that in controls (P<0.01) and during the course of treatment the number of platelets in peripheral blood of patients with CITP paralled to the level of IL-11. The platelet counts were obviously increased in all CITP patients after rhIL-11 treatment. It is concluded that the serum level of IL-11 in patients is correlated to the number of platelets in patients. rhIL-11 can be used as an effective treatment for CITP.
