In published cases and case series from Germany [50,61], France [51,57,58], Italy [59], Austria [60], Belgium [52], Australia [63], and the Netherlands [47], CAPA was most commonly mycologically diagnosed by either culture from BALF or tracheal aspirate and/or based on a positive GM or LFD from BALF or tracheal aspirate (Table 1). Across published cases, Aspergillus culture was positive in 29/35 (83%) of patients; of those with a positive culture and a reported source, 16/29 (55%) were recovered from—often undirected—BALF, 12/29 (41%) from tracheal aspirate, and 1/29 (3%) from sputum. In those where a BALF GM test was performed, 14/23 (61%) had a titer ≥1.5 ODI and 16/23 (70%) a titer ≥0.5 ODI, while 6/28 (21%) of those with serum GM results had a titer > 0.5 ODI. PCR from respiratory specimens or tissue was positive in 10/14 (71%) and LFD from tracheal secretion positive in 1/1 of patients.
