Fungal Status and Prognosis in ABPA (ABPAFUNGAL)
Clinical Characteristics and Prognostic Outcomes of Allergic Bronchopulmonary Aspergillosis Patients Stratified by Fungal Microbiological Status in Sputum or Bronchoalveolar Lavage Fluid: A Multicenter Bidirectional Cohort Study
This multicenter bidirectional cohort study aims to investigate the clinical characteristics and prognostic outcomes of patients with allergic bronchopulmonary aspergillosis (ABPA) stratified by fungal microbiological status in sputum or bronchoalveolar lavage fluid (BALF).
Patients diagnosed with ABPA according to the ISHAM 2024 criteria will be classified into fungal-positive and fungal-negative groups based on results from fungal culture, galactomannan (GM) testing, and metagenomic next-generation sequencing (mNGS) of sputum or BALF samples.
The study will compare baseline clinical features, laboratory findings, radiological characteristics, treatment response, and long-term outcomes, including acute exacerbation rate and time to first exacerbation, between the two groups.
All participants will be followed for up to 12 months with serial clinical and laboratory assessments.

Descrição
Inclusion Criteria:
1.Adult patients (≥18 years old) diagnosed with allergic bronchopulmonary aspergillosis (ABPA) according to the 2024 International Society for Human and Animal Mycology (ISHAM) diagnostic criteria.
2.Patients hospitalized during the study period in participating centers with sputum or bronchoalveolar lavage fluid (BALF) collection performed.
3.At least one mycological test performed on sputum or BALF, including fungal culture, galactomannan (GM) assay, metagenomic next-generation sequencing (mNGS), or targeted next-generation sequencing (tNGS), with clearly interpretable results (positive or negative).
4.Availability of complete and traceable clinical data, including medical history, imaging, laboratory tests, treatment records, and follow-up information, with no critical missing data.
5.Willingness to participate in follow-up and signed informed consent (for prospective participants), with good compliance for follow-up.
6.No systemic antifungal therapy or other interventions that may significantly affect mycological test results within 1 month prior to enrollment.
Exclusion Criteria:
1.Coexisting pulmonary fungal infections (e.g., invasive pulmonary aspergillosis) or other confirmed non-fungal pulmonary infections.
2.Presence of other structural lung diseases, such as pulmonary tuberculosis, lung cancer, or lung abscess.
3.Severe immunodeficiency or other significant allergic pulmonary diseases that may confound the diagnosis of ABPA.
4.Absence of sputum or BALF samples, or lack of valid mycological test results. 5.Incomplete key clinical data (e.g., total IgE, Aspergillus-specific IgE/IgG, imaging, or pulmonary function data) or inability to complete at least 3 months of follow-up.
6.Systemic antifungal treatment within 1 month prior to enrollment or participation in another interventional clinical trial.
7.Contraindications to bronchoscopy/BAL procedures or known severe allergy to relevant reagents used in testing.

Fungal-Positive ABPA
Patients diagnosed with allergic bronchopulmonary aspergillosis according to ISHAM 2024 criteria who demonstrate at least one positive result in sputum or bronchoalveolar lavage fluid (BALF) fungal testing, including fungal culture, galactomannan (GM) assay, or targeted next-generation sequencing (tNGS) detecting Aspergillus species.
|
|
Fungal-Negative ABPA
Patients diagnosed with allergic bronchopulmonary aspergillosis according to ISHAM 2024 criteria with negative results in all fungal tests performed on sputum or bronchoalveolar lavage fluid (BALF), including fungal culture, galactomannan (GM) assay, and targeted next-generation sequencing (tNGS).
