摘　　要：目的 评价重组人血小板生成素（rhTPO）联合静脉注射免疫球蛋白治疗儿童难治性ITP的临床疗效。方法对18例儿童难治性重型ITP进行rhTPO联合静脉注射免疫球蛋白治疗,rhTPO给予每次300U/kg,皮下注射,隔日一次,共7次,同时联合静脉注射免疫球蛋白每次5.0g,每周一次共4次,于rhTPO应用的第1天开始应用。结果 18例儿童难治性重型ITP有15例有效,其中6例完全缓解（随访中位时间6个月,有4例呈持续缓解）,9例部分缓解（其中4例维持3~4个月后血小板再次下降至≤20×109/L）,余3例患儿无效或血小板短暂性升高后快速下降至较低值。结论 rhTPO联合静脉注射免疫球蛋白可使部分难治性重型ITP患儿得到缓解,无明显毒副作用,可成为治疗儿童重型难治性ITP的一种方法。Objective To evaluate the effec of recombinant human thrombopoietin （rhTPO） combining intravenous im- munoglobulin （WIG） on children with severe refractory idiopathic thromboeytopenic purpura （ITP）. Methods 18 chil- dren with severe refractory ITP were given rhTPO Combining WIG. RhTPO （300μ/kg） was injected hypodermically once every other day with 7 times. At the same time that rhTPO was used on the first day, the seven day, the fifteen day and the twenty - first day,WIG （5.0g） was given. Results The treatment was effective on 15 children including 6 cases to- tally relieved and 9 cases partially remitted. The other 3 cases were not affected or showed that platelet （PLT） quantity increased briefly and then decreased quickly to a lower value. As to the 9 cases partially remitted, after 3 ~ 4 months, there were 4 children whose PLT quantity decreased below 20×109/L. As to the 6 cases totally relieved, in follow - up half a year,there were 4 children lastingly relieved. Conclusion RhTPO combining IVIG can relieve most of the chil- dren with severe refractory ITP, has no abviously toxic and adverse effects, and may be used to cure severe refractory ITP.
