Cystic Fibrosis Microbiome

Cystic Fibrosis Microbiome

Brief description of study

Among lung transplant recipients who survive to 5 years, half suffer from chronic lung allograft dysfunction (CLAD). This study will evaluate how changes in the lung microbiome may cause CLAD in Cystic Fibrosis patients who have been transplanted.

This is a case-control study of Cystic Fibrosis lung transplant recipients to define the lower respiratory tract microbiome at the time of incident CLAD and determine the relationship between allograft microbiome, host response, and CLAD.

Patients with clinical CLAD who are scheduled to undergo clinical bronchoscopy will be recruited for this study alongside matched control subjects that will undergo research bronchoscopy for sample collection.

Subjects will be recruited from established patients within the University of Pennsylvania, Johns Hopkins University, and University of Pittsburgh Lung Transplant Programs.
