TxIA-allo-HSCT indicates time interval from start of antifungal therapy for IA and allo-HSCT.
All P values were calculated with the chi-square statistic or Fisher exact test except for comparisons of cumulative incidence estimates, which were compared with a univariate Cox regression model (detailed in “Statistical analysis”).
GM positivity in serum (index ≥ 0.8 twice) without culture isolation of the causative species. An additional 24 patients had positive GM in serum and isolation of the causative Aspergillus spp, and 1 patient had 2 species isolated from the same sample (A fumigatus and A niger).
All breakthrough infections occurred under systemic antifungal secondary prophylaxis. One patient on voriconazole developed proven disseminated fusariosis, 1 on itraconazole developed a central nervous system infection from an unidentified fungus with pseudohyphae, and 1 patient on itraconazole developed proven pulmonary zygomycosis.
All outcomes analyzed at 2 years after transplantation.
