## TL;DR

This study shows that basiliximab can be used as an alternative to calcineurin inhibitors for preventing acute GVHD in patients who cannot tolerate these drugs after stem cell transplants.

## Contribution

Demonstrates basiliximab as a short-term alternative for GVHD prophylaxis in CNI-intolerant allo-HSCT patients.

## Key findings

- 17 patients tolerated basiliximab with acceptable GVHD rates and engraftment success.
- 62.6% overall survival at 6 months with no Cytomegalovirus disease despite viral reactivation.
- Basiliximab was effective in preventing severe GVHD in CNI-intolerant patients.

## Abstract

探讨在钙调蛋白抑制剂（CNI）不耐受患者中短期应用重组抗CD25人源化单克隆抗体巴利昔单抗（Basiliximab）单药预防异基因造血干细胞移植（allo-HSCT）后急性移植物抗宿主病（GVHD）的有效性。

本研究纳入2021年8月至2022年8月在上海闸新中西医结合医院骨髓移植科行挽救性allo-HSCT后因CNI严重不良反应而应用巴利昔单抗预防急性GVHD的17例难治性恶性血液病患者。男7例，女10例，中位年龄43（18～67）岁。停用CNI后，给予巴利昔单抗1 mg/kg每周1次进行替代预防，直至患者有条件重新启用CNI或哺乳动物雷帕霉素靶体蛋白（mTOR）抑制剂。

巴利昔单抗的替代预防中位开始时间为移植后5（1～32）d，替代治疗中位持续时间为20（7～120）d。所有患者均获得粒细胞植入，中位植入时间12（10～17）d。13例患者获得血小板植入，中位植入时间13（11～20）d。8例（47.1％）患者发生Ⅱ～Ⅳ度急性GVHD，4例（23.6％）发生Ⅲ/Ⅳ度急性GVHD。仅有1例患者死于急性GVHD。至随访截止，17例患者中7例死亡，存活患者中随访最长时间为347 d，中位生存时间未达到，移植后6个月总生存率为62.6％。17例患者中，13例（76.4％）发生巨细胞病毒再激活，7例（41.2％）发生EB病毒激活，未发生巨细胞病毒病。

在allo-HSCT过程中出现CNI不耐受时，短期单药应用巴利昔单抗可作为急性GVHD的替代预防方案。
