Randomized Controlled Trial
Antibiotic exposure and interpersonal variance mask the effect of ivacaftor on respiratory microbiota composition.
G551D is a class III mutation of the cystic fibrosis transmembrane regulator (CFTR) that results in impaired chloride channel function in cystic fibrosis (CF). Ivacaftor, a CFTR-potentiating agent improves sweat chloride, weight, lung function, and pulmonary exacerbation rate in CF patients with G551D mutations, but its effect on the airway microbiome remains poorly characterised. ⋯ The short-term impact of ivacaftor therapy on sputum microbiota composition in patients with G551D mutations are modest compared to those resulting from antibiotic exposure, and may be masked by changes in antibiotic treatment regimen.

Cystic fibrosis (CF) affects multiple organs including the lung, liver, and pancreas. Lung transplant, liver transplant, and combined lung-liver transplant have become well-established therapies for CF patients with end-stage organ failure. Thus far, however, there has been limited experience with pancreas transplantation in CF. In this report, we detail the clinical history, transplant procedure, and post-operative recovery of a patient who underwent combined lung-liver-pancreas transplant for advanced CF.
