Abstract
目的观察儿童及青少年血液病患者单倍型造血干细胞移植(haplo-HSCT)后出血性膀胱炎(HC)的临床特征并探讨其影响因素。方法回顾性分析2015至2016年接受haplo-HSCT的89例儿童及青少年血液病患者的临床资料。结果全部89例患者中,≤14岁62例(儿童组)、>14~<18岁27例(青少年组);男56例,女33例;中位移植年龄10(1~17)岁;急性淋巴细胞白血病(ALL)44例,急性髓系白血病(AML)33例,急性混合细胞白血病(AHL)3例,骨髓增生异常综合征(MDS)9例。移植物来源均为骨髓+外周血干细胞。全部89例患者中32例(36%)发生HC,其中迟发型31例,早发型1例;Ⅰ度6例、Ⅱ度16例、Ⅲ度8例、Ⅳ度2例;HC发病中位时间为移植后25(2~55)d,中位持续时间为19(3~95)d;所有患儿均获得治愈。儿童组HC发病率低于青少年组[27.4%(17/62)对55.6%(15/27),χ2=6.466,P<0.05]。儿童组中<5岁组HC发生率低于5~14岁组[0(0/12)对34%(17/50),χ2=4.043,P<0.05]。结论HC是儿童及青少年血液病患者haplo-HSCT的常见并发症,总体预后良好,年龄是其发生的影响因素。
