2.1 参与者数量分析 纳入患者8例,治疗过程无脱落,均进入结果分析。 2.2 移植物抗宿主病的累及器官 8例移植物抗宿主病患者中,2例为急性移植物抗宿主病; 6例为慢性移植物抗宿主病,其中2例(病例4,病例6)由急性移植物抗宿主病演变而来。8例移植物抗宿主病患者的病变累及多个器官,其中皮肤5例,口腔3例,眼睛3例,肝脏2例,胃肠道2例,肺脏1例,膀胱1例。 2.3 间充质干细胞的治疗效果 所有患者均在原有免疫抑制剂治疗的基础上接受间充质干细胞治疗。1例输注1次,5例输注2次,1例输注3次,1例输注4次。输注期间所有患者均未出现输液相关不良反应。8例患者中6例经间充质干细胞治疗有效(2例完全缓解,4例部分缓解),2例无效。各受损靶器官治疗反应见表1。5例皮肤病变中4例均得到改善,1例无效,1例在移植后21个月出现硬皮病样慢性移植物抗宿主病,用雷帕鸣治疗后有所改善,1个月后因急性阑尾炎行阑尾切除术,术后切口一直无法愈合,在输注间充质干细胞2次后伤口痊愈。3例口腔病变中2例得到完全缓解,1例部分缓解。2例肝脏病变以及2例胃肠道病变均获得完全缓解。3例眼睛病变用间充质干细胞治疗无效。 2.4 间充质干细胞输注治疗移植物抗宿主病综合评价 见表1。 2.5 间充质干细胞对闭塞性系支气管炎的治疗效果 病例6在移植后11个月出现胸闷、气促,肺部CT提示双肺炎症,左肺下叶不张,右肺上叶、中叶、左肺上叶肺气肿。 纤维支气管镜取右肺背段组织病理检查提示:肺泡间隔增厚伴淋巴细胞浸润。诊断为闭塞性细支气管炎,用抗生素以及大剂量甲基强的松龙治疗后气促逐渐好转,但是患者需要依赖氧疗生活,在输注间充质干细胞2个疗程后患者可以脱离吸氧。2个月后患者又出现严重气促,再次输注间充质干细胞2个疗程后无效果。 2.6 间充质干细胞对膀胱移植物抗宿主病的治疗效果 病例7在移植后25 d出现出血性膀胱炎,检测血以及尿巨细胞病毒DNA均为阳性,在持续膀胱冲洗的基础上,先后予更昔洛韦以及膦甲酸钠治疗后巨细胞病毒DNA转为阴性,但是患者仍有出血性膀胱炎。考虑膀胱移植物抗宿主病的可能性,先后予甲强龙、他克莫司的免疫抑制治疗,患者出血性膀胱炎症状仍有反复。于输注间充质干细胞2次后症状无改善。最后患者行膀胱镜+膀胱黏膜电切活检术,膀胱黏膜病理:送检少许变性纤维组织,表面未见确切披覆上皮,可见少量血块,间质小血管丰富,呈慢性炎症改变。 2.7 临床转归 截止至2013年12月31日,随访中位时间28(7-62)个月。2例完全缓解患者中,病例6在移植后13个月(输注间充质干细胞后7个月)因疾病复发死亡,病例8在移植后4个月(输注间充质干细胞后1个月)因并发中枢神经系统移植后淋巴增殖性疾病而死亡。4例部分缓解患者中,病例3因急性髓细胞白血病复发导致的中枢神经系统白血病,于移植后30个月(输注间充质干细胞后23个月)死亡;其他3例患者随访中位时间41 (26-59)个月,目前已经停用免疫抑制剂;病例4移植后11个月(输注间充质干细胞后3个月)出现外周移植后淋巴增殖性疾病,经美罗华治疗后缓解。2例无效患者均死亡,病例5因闭塞性细支气管炎于移植后23个月(输注间充质干细胞后10个月)死于呼吸功能衰竭;病例7因并发严重感染以及移植后淋巴增殖性疾病死亡。 2.8 不良反应 8例患者总共输注间充质干细胞18次,所有患者均未出现输液相关不良反应。"
