Objectives

Narrative objectives1

We evaluate the microbiome in bronchoalveolar lavage fluid (BALF) of the pulmonary lesions obtained from patients with chronic pulmonary aspergillosis and the relationship between the microbiome and the pathogenesis (clinical features, chest CT findings or disease type) or the progression (prognosis, duration of disease, and clinical response to antimicrobial drugs).
We also evaluate the ability of phagocytosis against coexisting bacteria and fungi decline and the ability to differentiate functional macrophages, such as M1 and M2 macrophages in patients with chronic pulmonary aspergillosis that have deteriorated rapidly.

Basic objectives2

Others

Basic objectives -Others

We evaluate the relationship between bacterial phylotype that is detected using the bacterial flora analysis and chest CT findings of patient with chronic pulmonary aspergillosis.

Developmental phase



Assessment

Primary outcomes

The relationship between microbiome and chest CT findings of patients with chronic pulmonary aspergillosis.

Key secondary outcomes

We evaluate the following problems at the start of the test and 24 to 28 weeks and 48 to 52 weeks after this trial started.

1) Clinical manifestations, laboratory findings

2) Microbiological evaluation:
Transition of causative bacteria with sputum

3) Cytokines, oxidative stress markers in BALF (including TNF-a, NOS, HO-1, IL-4, IL-6, IL-8, IL-13 and others).

4) The time-dependent change of the CT findings

5) The statistically significant differences in the differentiation ability according to the macrophages phenotypes (proportion of macrophages phenotype), and the CT findings.

Key inclusion criteria

Patients with suspected chronic pulmonary aspergillosis and do not conflict with the exclusion criteria are registered.
We use the criteria of the Guidelines for Management of Deep-seated Mycoses in Japan were revised in February 2014 to diagnosis chronic pulmonary aspergillosis.
Patients who are positive for serum anti-Aspergillus sedimentation antibody, Aspergillus GM antigen, B-D glucan or histopathological findings are defined clinical diagnosis.
Patients who are positive for culture tests are defined confirmed diagnosis.

Key exclusion criteria

The following patients are excluded.
1. Patients who do not agree with this study
2. Patients for whom bronchoscopy is difficult to preform because of comorbidity and who do not agree with bronchoscopy
3. Patients who received antibiotic therapy within 3 days before bronchoscopy. (Excluding small-volume long-term therapy of macrolide drugs)
