概括
一种新的塔克罗利斯,降低剂量的甲铁酸盐和mycophenolate mofetil (mini-MTX/MMF) 治疗方案显示了类似的急性移植对宿主病率,但与标准塔克罗利斯/甲铁酸盐 (全MTX) 相比,在HCT后有所改善的毒性.
科学领域:
- 造血干细胞移植 (HCT) 的方法
- 免疫抑制是一种免疫抑制.
- 移植对宿主疾病 (GVHD) 预防 预防
背景情况:
- 标准的塔克罗利斯/甲托雷克萨特 (Tac/MTX) 用于在异性造血细胞移植 (HCT) 后的移植对宿主疾病 (GVHD) 预防.
- 这种标准疗法与显著的毒性有关,促使人们研究替代策略.
- 之前的研究探讨了降低剂量的甲状腺素 (迷你MTX) 和甲酸 (MMF),但缺乏与标准MTX的直接比较.
研究的目的:
- 为了比较Tac/mini-MTX/MMF与标准Tac/full-MTX的疗效和安全性,用于预防神经损伤性HCT中的GVHD.
- 评估主要终点,包括急性GVHD (aGVHD),粘膜炎和移植.
- 评估二次终点,如慢性GVHD (cGVHD),器官毒性,感染,复发,非复发死亡率 (NRM) 和整体存活率 (OS).
主要方法:
- 一项随机试验涉及96名患者,他们接受了第一个骨髓衰变性HCT,用8/8 HLA匹配的供体.
- 患者被分配给接受TAC/全MTX或TAC/迷你MTX/MMF用于GVHD预防.
- 大多数患者 (86%) 使用了骨髓移植.
主要成果:
- 迷你MTX/MMF (28%) 和全MTX (27%) 组之间的 2-4 级aGVHD 没有显著差异 (P = .41).
- 迷你MTX/MMF组显示较低的3-4级粘膜炎和更快的移植.
- 迷你MTX/MMF疗法与较少的毒性和呼吸衰竭有关,与较低的非复发死亡率 (11%与22%相比;P = .06) 相伴.
结论:
- 塔克罗利木斯与降低剂量的甲铁和甲酸莫菲提尔 (迷你MTX/MMF) 结合,在预防2至4级aGVHD方面,其疗效与标准的Tac/全MTX相当.
- 迷你MTX/MMF疗法显示出更有利的毒性概况,包括减少粘膜炎和器官毒性.
- 进一步的研究是有必要的,以优化迷你MTX/MMF治疗方案,特别是在观察到较高的严重aGVHD的发病率方面.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
201
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
