| Cohort | This was a prospective study conducted between March 2015 and November 2017 at the Department of Respiratory and Critical Care Medicine, Nanjing Jinling Hospital, China. 211 BALF samples and 307 plasma samples of patients with pulmonary aspergillosis were collected and divided into aspergillosis groups (BALF n = 51, 35 proven, 16 probable; plasma n = 89, 51 proven, 38 probable). Aspergillosis subjects were then divided into IPA, SAIA and CPA (excluding SAIA) subgroups (BALF: 17 IPA, 19 SAIA and 15 CPA; plasma: 28 IPA, 20 SAIA and 41 CPA). |

| Disease Introduction Mechanism | Pulmonary aspergillosis is a severe mycosis caused mainly by Aspergillus fumigatus. In recent years, reports of pulmonary aspergillosis have increased in non-neutropenic patients, including subjects with chronic obstructive pulmonary disease (COPD), cavitary pulmonary tuberculosis, bronchiectasis, chronic kidney disease, diabetes, patients who use glucocorticoids or immuno- suppressants, and for those with other critical conditions. Non-neutropenic patients with aspergillosis have atypical symptoms and imaging ndings, and early diagnosis is dif cult, contributing to a high mortality rate and unnecessary medical ex- penses. The updated Infectious Diseases Society of America (IDSA) guidelines recommend bronchoalveolar lavage uid (BALF) gal- actomannan (GM) and aspergillus IgG antibody testing for diag- nosing chronic forms of pulmonary aspergillosis. Our previous work has con rmed that the BALF galactomannan (GM) testing offers diagnostic value. However, invasiveness, numerous false positives, and the lack of standardization suggest that better bio- markers for diagnosing aspergillosis are needed, especially for the early diagnosis of invasive pulmonary aspergillosis (IPA) and sub- acute invasive aspergillosis (SAIA) in non-neutropenic patients. |
