目的：　探讨丙种球蛋白、强的松联合治疗血小板减少性紫癜(ITP)的近期疗效。方法：　观察组采用蓉生静丙,剂量每日400mg/kg,连用5d,后续用强的松治疗4周;对照组单用强的松4～6周。 结果：　观察组血小板达高峰时间为1～2周,峰值约180×10 9/L,总有效率为86.7%;对照组上述数值分别为4周,116×10 9/L和40% (P<0.05)。结论：　丙种球蛋白、强的松联合治疗ITP明显优于单用强的松组。

OBJECTIVE: To evaluate the therapeutic effect on children with acute idiopathic thrombocytopenic purpura (AITP) by intravenous immunoglobulin (IVIG) or dexmethasone (DEX). METHODS: Fortysix patients aged from 4 months to 14 years with AITP were randomized to receive IVIG or DEX, and we monitored the platelet count (Tc) and observed the side effects after each treatment. RESULTS: There was no difference in the lasting time of Tc≤20×109/L and the time when Tc increased to ≥50×109/L between the treatment of IVIG and DEX (P>0.05). But the percentage of patients with Tc≥50×109/L was higher in the IVIG group Ⅱ (88%) than in the DEX group (50%) after the 5 day treatment (P<0.05). CONCLUSIONS: We may choose IVIG to treat the patients with AITP complicated by severe mucomenbrane and organ bleeding, while we may use DEX if the patients have no complication.
