JCC:异基因骨髓间充质基质细胞疗法在治疗肛瘘克罗恩病患者的长期疗效分析

2019-12-27 不详 MedSci原创

目前对于异基因骨髓间充质基质细胞[bmMSC]治疗肛周克罗恩病[CD]瘘管的长期安全性和疗效尚不清楚,因此,本项研究就旨在根据相关研究结果对bmMSC治疗CD肛瘘的疗效进行分析。

背景和目标
目前对于异基因骨髓间充质基质细胞[bmMSC]治疗肛周克罗恩病[CD]瘘管的长期安全性和疗效尚不清楚,因此,本项研究就旨在根据相关研究结果对bmMSC治疗CD肛瘘的疗效进行分析。

方法
本项研究的开展时间为2012-2014年,研究人员在莱顿大学医学中心对21例难治性肛周瘘管克罗恩病患者进行了局部bmMSC治疗的双盲试验。所有接受bmMSC治疗的患者分为三组进行不同剂量的bmMSC治疗:[队列1:1 x 107 bmMSCs,n=5;队列2:3×107 bmMSC组,n=5;队列3:9×107 bmMSC组,n=5]进行为期4年的评估。记录临床事件,评估瘘管闭合,并评估抗人白细胞抗原[HLA]抗体。

结果
15例接受bmMSC治疗的患者中有13例(87%)进行了长期随访。观察到两个非MSC相关的恶性肿瘤的发生。所有患者均未发现与bmMSC治疗有关的严重不良事件。在队列2中[ n=4],bmMSC治疗后4年所有瘘管均闭合。队列1 [ n=4]占63%,队列3 [ n=5]占43%。在治疗后的24周和4年中,没有患者能检测到抗HLA抗体。盆腔MRI显示4年后所有患者瘘管明显缩小。

结论
本项研究结果表明同种异体bmMSC治疗CD相关性肛瘘也是一种安全的治疗方法。
