Abstract
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 ≥12years 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 27years (12-59years) 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 (>6weeks 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.
