The goal of this study is to identify the immunological factors that influence a patient's response to the presence of the fungus Aspergillus fumigatus (A. fumigatus) in the lungs. In patients with cystic fibrosis (CF), this fungus is not known to cause damage to the lungs, but some patients respond with an allergic reaction that cause them to wheeze, cough, or have difficulty breathing. Approximately 230 patients will be enrolled with an additional 60 people who do not have CF and who do not have a history of asthma to serve as a comparison group.

Further study details as provided by University of Pittsburgh:

Primary Outcome Measures:
  • To test the hypothesis that the white blood cells of CF patients with ABPA will demonstrate increased inflammatory cytokine expression in response to binding of A. fumigatus antigens compared to white blood cells from non-ABPA patients. [ Time Frame: baseline, 6 month follow-up, ABPA exacerbation ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To test the hypothesis that T cells from CF patients with ABPA will have decreased adaptive regulatory function [ Time Frame: baseline, 6 month follow-up, ABPA exacerbation ] [ Designated as safety issue: No ]
  • To test the hypothesis that surface-bound TGF beta is critical for the development and maintenance of immune tolerance to A. fumigatus antigens [ Time Frame: baseline, 6 month follow-up, ABPA exacerbation ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
The CF subject's blood will be processed to establish a cell line (lymphocyte transformation) for a source of DNA for future genetic studies.

Estimated Enrollment: 300

CF (non-ABPA)
cystic fibrosis and culture positive for A. fumigatus in airway cultures.
cystic fibrosis and diagnosis of ABPA
healthy control
healthy non-CF


Ages Eligible for Study:   6 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Male and female subjects with CF who have A. fumigatus in cultures of their airway flora and receive clinical care at the Antonio J. and Janet Palumbo Cystic Fibrosis Center at Children's Hospital of Pittsburgh. Age (± 1 year) and sex matched healthy, non CF controls will also be recruited.

  • age and sex matched to CF population

Exclusion Criteria:


  • uncontrolled CF-related diabetes mellitus
  • use of oral steroids at a dose ≥ 0.5 mg/kg/day
  • history of lung transplantation
  • pulmonary exacerbation as defined by requirement for use of intravenous antibiotics or need for hospitalization within the preceding 14 days.
  • patients who have a diagnosis of HIV and have a CD4+ Tcell count below 500 cells/ml will be excluded (control)
  • asthma
