The role of pre-HCT chest high-resolution computed tomography (HRCT) and serum galactomannan index (GMI) in predicting the post-allogeneic hematopoietic cell transplant (HCT) invasive pulmonary aspergillosis (IPA) is debatable.
This was a single-center, prospective study from 2014 to 2019. The primary objective was to study if pre-HCT chest HRCT and serum GMI predicted IPA post-HCT. The secondary objective was day +100 mortality. All consecutive, consenting patients of ≥12 years of age undergoing allo-HCT were included and had pre-HCT chest HRCT and serum GMI. All patients received mold active antifungal prophylaxis. The EORTC/MSG criteria were used for the diagnosis of IPA.
A total of 82 patients with median age 27 years (12-59 years) were included. The underlying diagnoses included hematological malignancies (79%) and aplastic anemia (21%). Fifteen percent of patients was treated for prior history of probable IPA (>6 weeks before HCT). Pre-HCT chest HRCT satisfied EORTC clinical criteria in 24% patients. Serum GMI ≥0.5 was seen in 27% of patients. Post-HCT probable IPA was seen in 24% of patients. There were more patients with pre-HCT chest HRCT findings satisfying EORTC clinical criteria (45% vs. 18%, P = .014) and GMI ≥0.5 (45% vs. 21%, P = .03) in the group with post-HCT IPA compared to those without IPA. There was higher day+100 mortality in patients with post-HCT IPA (55% vs. 18%, P = .001).
The presence of EORTC clinical criteria on pre-HCT chest HRCT, serum GMI ≥0.5, and prior history of IPA predicted post-HCT IPA.
异体造血细胞移植（HCT）前胸部高分辨率计算机断层扫描（HRCT）和血清半乳甘露聚糖指数（GMI）在预测异基因 HCT 后侵袭性肺曲霉病（IPA）中的作用存在争议。
这是一项 2014 年至 2019 年进行的单中心前瞻性研究。主要目的是研究 HCT 前胸部 HRCT 和血清 GMI 是否预测 HCT 后 IPA。次要目标是第 100 天死亡率。所有连续同意接受 allo-HCT 的年龄≥12 岁的患者均纳入研究，并进行 HCT 前胸部 HRCT 和血清 GMI 检查。所有患者均接受了 mold 活性抗真菌预防。EORTC/MSG 标准用于 IPA 的诊断。
共纳入 82 例中位年龄为 27 岁（12-59 岁）的患者。基础诊断包括血液系统恶性肿瘤（79%）和再生障碍性贫血（21%）。15%的患者因 HCT 前 6 周内有疑似 IPA 的病史而接受治疗。24%的患者 HCT 前胸部 HRCT 满足 EORTC 临床标准。27%的患者血清 GMI≥0.5。24%的患者出现 HCT 后疑似 IPA。与无 IPA 的患者相比，HCT 后 IPA 组有更多的患者满足 EORTC 临床标准（45%比 18%，P=0.014）和 GMI≥0.5（45%比 21%，P=0.03）。HCT 后 IPA 患者的第 100 天死亡率更高（55%比 18%，P=0.001）。
HCT 前胸部 HRCT 上存在 EORTC 临床标准、血清 GMI≥0.5 和 IPA 既往史可预测 HCT 后 IPA。
