About

The main aim of this study is to determine whether the levels of different inflammatory cytokines in the serum and BALF (bronchoalveolar lavage fluid) are relative to the severity and exacerbations of ABPA (allergic bronchopulmonary aspergillosis).

Full description

The study would record patients' medical data at baseline and follow them up for different period of time. Updated data would be recorded and blood( or BALF) of the patients would be drawn for tests or stored as whole blood or serum at -80℃ when patients visit the hospital. Then the cytokine (A panel set by the manufacturer) of the serum and BALF would be tested . The secretion ability of peripheral blood mononuclear cells would also be verified. The investigators would then analyze the data and see if any cytokine is relative to the exacerbation or other indicators of the severity of ABPA.

Inclusion and exclusion criteria

For ABPA patients

Inclusion Criteria:

• Patients diagnosed as allergic bronchopulmonary aspergillosis (ABPA). The diagnosis criteria of ABPA is as following: clinical diagnosis of asthma, elevated total IgE levels (> 1,000 IU/mL), presence of specific IgE against A fumigatus detected (> 0.35 kUA/L) or type 1 skin reaction to Aspergillus antigen. Other criteria(at least two of three): Presence of serum IgG antibodies (precipitins) against A. fumigatus; Radiographic pulmonary opacities consistent with ABPA(It might be transient consolidation, nodules, finger-in-glove opacities. Or it could be permanent bronchiectasis and pleuropulmonary fibrosis) Patients who sighed consent forms.

For asthma patients:

Diagnosis according to GINA.

For healthy control:

People with ongoing chronic allergic disease such as allergic rhinitis, asthma and allergic dermatitis are excluded.

Exclusion Criteria:

• Patients who are unwilling to sign the consent form.
