## TL;DR

This study identifies the main causes of death before blood cell recovery in patients who received stem cell transplants, with infection being the most common cause.

## Contribution

The study provides detailed insights into pre-engraftment mortality causes and patient-specific risk factors after allogeneic stem cell transplantation.

## Key findings

- Infection was the leading cause of pre-engraftment mortality (39.3%).
- Preparatory treatment heart toxicity was the main cause in severe aplastic anemia patients (71.4%).
- Intracranial hemorrhage was often linked with severe infections in deceased patients (53.3%).

## Abstract

分析异基因造血干细胞移植（allo-HSCT）患者粒细胞植入前死亡原因及人群特征。

对2016年1月至2023年7月在北京大学人民医院行allo-HSCT的全部7 427例患者进行回顾性分析。

7 427例患者中有56例（0.75％）在中性粒细胞植入前死亡，中位死亡时间为+7 d（−3 d～+38 d）。急性白血病（AL）、重型再生障碍性贫血（SAA）、骨髓增生异常综合征（MDS）患者的中位死亡时间分别为+11 d（−1 d～+38 d）、+3 d（−1 d～+ 34 d）、+16 d（−1 d～38 d）（P＝0.013）。主要死亡原因为感染（39.3％）、预处理心脏毒性（28.6％）和颅内出血（26.8％）。感染是引起AL和MDS患者最常见的死亡原因（55.0％、60.0％）。预处理心脏毒性所致死亡主要见于SAA患者（71.4％），而在AL患者中未见到，MDS中仅1例。53.3％的颅内出血死亡患者合并严重感染。感染、预处理心脏毒性、颅内出血引起植入前死亡的中位时间分别是+11 d（−1 d～+38 d）、+2.5 d（−1 d～+17 d）、+8 d（−3 d～+37 d）（P<0.001）。

感染是allo-HSCT患者粒细胞植入前死亡的主要原因，SAA患者应关注严重心脏毒性导致的植入前死亡。
