## TL;DR

This study examines the clinical features and outcomes of patients with immune thrombocytopenia and lung bleeding.

## Contribution

It identifies risk factors and treatment strategies for a rare complication of immune thrombocytopenia.

## Key findings

- Patients presented with acute respiratory failure and low platelet counts.
- High D-dimer levels and failed infection control were linked to higher mortality.
- Combining immune suppression with infection treatment improved survival.

## Abstract

探讨原发免疫性血小板减少症（ITP）合并弥漫性肺泡出血（DAH）的临床特征及预后。

回顾性分析2015年1月至2024年6月北京大学人民医院收治的5例ITP合并DAH患者数据，统计患者的基本特征、临床症状、实验室检查、影像学检查及治疗反应，评估患者的生存情况和预后因素。

患者均为女性，中位年龄56（38～66）岁，4例为慢性ITP，3例合并感染。主要症状为皮肤黏膜出血（3/5）、呼吸困难（3/5）及咯血（2/5），中位PLT 51（1～83）×109/L，D-二聚体显著升高［中位值870（220～8 578）ng/ml］。胸部CT示双肺弥漫性磨玻璃影（3/5）、实变影（1/5）及支气管充气征（1/5）。3例完全缓解，2例死亡。

ITP合并DAH以急性呼吸衰竭为主要表现，D-二聚体升高及感染控制失败是死亡的高危因素，早期联合免疫抑制与抗感染治疗可改善预后。
