目的:评价小剂量利妥昔单抗(Rituximab,RTX)治疗系统性红斑狼疮(SLE)合并血小板减少症的疗效及安全性。方法9例继发于SLE的血小板减少症患者,给予静脉滴注利妥昔单抗100mg,每周1次,连用2~4次,同时根据病情联合使用激素等免疫抑制剂。观察患者临床表现和不良反应,比较患者治疗前后各项临床指标的变化。结果第一次使用利妥昔单抗后,6例(66.7%)患者在2~4周内血小板计数上升至正常,随访6~12个月后,其中3例患者维持完全缓解,3例患者复发,但在加用环孢 A和/或达那唑后,血小板又上升至正常且维持良好。1例达部分缓解,2例无效(其中1例死亡)。在随访期间,患者的激素用量均逐步减少。研究期间1例患者发生隐球菌脑膜炎。结论小剂量利妥昔单抗对部分SLE合并血小板减少症有效,安全性较好,但需谨慎除外感染。该生物试剂可能成为免疫相关的血小板减少症的诱导缓解手段之一。
目的:評價小劑量利妥昔單抗(Rituximab,RTX)治療繫統性紅斑狼瘡(SLE)閤併血小闆減少癥的療效及安全性。方法9例繼髮于SLE的血小闆減少癥患者,給予靜脈滴註利妥昔單抗100mg,每週1次,連用2~4次,同時根據病情聯閤使用激素等免疫抑製劑。觀察患者臨床錶現和不良反應,比較患者治療前後各項臨床指標的變化。結果第一次使用利妥昔單抗後,6例(66.7%)患者在2~4週內血小闆計數上升至正常,隨訪6~12箇月後,其中3例患者維持完全緩解,3例患者複髮,但在加用環孢 A和/或達那唑後,血小闆又上升至正常且維持良好。1例達部分緩解,2例無效(其中1例死亡)。在隨訪期間,患者的激素用量均逐步減少。研究期間1例患者髮生隱毬菌腦膜炎。結論小劑量利妥昔單抗對部分SLE閤併血小闆減少癥有效,安全性較好,但需謹慎除外感染。該生物試劑可能成為免疫相關的血小闆減少癥的誘導緩解手段之一。

ABSTRACT:OBJECTIVE To investigate the clinical efficacy and safety of low-dose rituximab in the treatment of systemic lupus erythematosus ( SLE) patients with thrombocytopenia.METHODS Nine SLE patients,were treated with rituximab ( weekly infusion of 100mg for 2~4 consecutive weeks) intravenously,in combination with corticoste-roids and immunosuppressive drugs as needed for patient′s condition.The observation indexes were serology markers and adverse events.RESULTS After the fisrt infusion of rituximab,platelet count increased to normal level within two to four weeks in six patients ( 66.7%).Three of six patients maintained complete response.Three patients re-curred,but the platelet count returned to normal level after added cyclosporin A and/or Danazol.One patient a-chieved partial response.Two patients did not respond,One of them died.During the study,the dose of prednisone re-duced gradually.One patient infected cryptococcal meningitis during rituximab therapy.CONCLUSION Low-dose rituximab is a effective and safe treatment for SLE patients with thrombocytopenia at least in part,but screening of in-fections should be carried out in all candidate.Rituximab appeared to be a promising induction treatment for systemic lupus erythematosus patients with thrombocytopenia.
