Clinical Case Study: Recognizing and explaining the symptoms of Cystic Fibrosis
Stacy is completing her internship in Internal Medicine and is presented with a patient who complains of difficulty breathing, frequent sinus infections, and a chronic cough that produces extremely thick mucus. Stacy immediately recognizes these as possible symptoms of a condition known as Cystic Fibrosis. Without performing a genetic test, there is no way to be 100% certain of the diagnosis, but Stacy would like to be able to explain what is happening in her patient’s airways.
Case Background
From her Human Anatomy and Physiology course in medical school, Stacy recalls that Cystic Fibrosis is caused by a mutation in a gene that codes for the CFTR Transmembrane Channel Protein. This channel facilitates the flow of water and Chloride ions into and out of the cells in our lungs. When this channel becomes non-functional, Chloride ions get trapped inside of our lung cells. Through osmosis, water also flows into our lung cells. This produces a very thick layer of mucus in our airways, which causes most of the symptoms that Stacy’s patient is experiencing.
