Idiopathic pulmonary hemosiderosis (IPH) is a rare immunological disease with a genetic predisposition. It is characterized by recurrent episodes of diffuse alveolar hemorrhage (DAH). Timely use of immunosuppressive medications has significantly improved overall outcomes, including mortality. Still, uncontrolled and frequent episodes of DAH can eventually cause pulmonary fibrosis, leading to end-stage lung disease (ESLD). The objective of the present project was to scrutinize the literature and summarize the demographic, clinical, radiological, and histopathological features, as well as the overall outcomes, in this patient population following lung transplant. The Medline database was searched using the PubMed platform. Articles published in English between 1960 and 2020 were included in the search. Different search terms were used to identify all patients who underwent lung transplantation to manage ESLD due to IPH. Only four cases of lung transplantation have been reported in the literature in patients with IPH. All but one of these underwent deceased donor lung transplant; recurrence was reported in two of these patients and suspected in the third. One patient received living donor lung transplant and had no recurrence during a five-year follow-up. Patients with IPH should not be excluded from lung transplantation because the disease may not recur in all patients, and even when it does recur it can be promptly treated by increasing immunosuppression.
特发性肺含铁血黄素沉着症(IPH)是一种具有遗传易感性的罕见免疫性疾病。其特征是反复发作弥漫性肺泡出血(DAH)。及时使用免疫抑制药物显著改善了总体预后,包括死亡率。然而,不受控制和频繁的 DAH 发作最终可导致肺纤维化,导致终末期肺病(ESLD)。本项目的目的是仔细研究文献,总结肺移植后这一患者群体的人口统计学、临床、放射学和组织病理学特征以及总体预后。使用 PubMed 平台检索 Medline 数据库。纳入了 1960 年至 2020 年期间发表的英文文章。使用不同的搜索词来确定所有因 IPH 导致 ESLD 而行肺移植的患者。在文献中仅报道了 4 例 IPH 患者行肺移植。除 1 例外,其余均行已故供者肺移植;其中 2 例患者报告复发,第 3 例患者疑似复发。1 例患者接受活体供者肺移植,5 年随访期间无复发。不应该将 IPH 患者排除在肺移植之外,因为并非所有患者的疾病都会复发,即使复发,也可以通过增加免疫抑制来迅速治疗。
