Impact of Highly Effective Modulator Therapy on the Cystic Fibrosis Microbiome

The goal of this observational study is to learn about the effects of a specific cystic fibrosis therapy (Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy) on chronic sinonasal disease. The main questions it aims to answer are: 1. How does this therapy impact bacterial communities in the paranasal sinuses? 2. How does this therapy impact inflammation in the paranasal sinuses and olfactory cleft? 3. How does this therapy impact sense of smell and sinonasal disease burden in individuals with cystic fibrosis? 4. How does this therapy impact disease-specific and general quality of life of individuals with cystic fibrosis? Participants will be asked to provide samples from their nose, complete testing of their sense of smell, and complete surveys about their quality of life and sense of smell in this study. Researchers will compare study results between patients who are currently undergoing Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy and patients who are not currently undergoing therapy.
