This study is looking at the connection between vitamin D and special immune cells in your lungs called macrophages in people with idiopathic pulmonary fibrosis (IPF)—a disease where lung tissue becomes scarred and stiff over time. Researchers want to understand whether people with IPF have lower vitamin D levels and whether their lung immune cells behave differently than they should. By comparing blood and lung fluid samples from people with IPF to samples from people with other lung diseases and lung cancer, the researchers hope to uncover new insights that could eventually lead to better treatments.
IPF is a serious condition that damages the lungs, but doctors still don't fully understand all the factors that drive the disease. Some early evidence suggests vitamin D and immune cell behavior may play a role, but this hasn't been studied thoroughly in IPF patients. This research aims to fill that gap and potentially open the door to new treatment approaches.

As a participant, you would be asked to provide blood samples and possibly samples from your lungs or airways. The researchers will analyze these samples to measure your vitamin D levels and examine your immune cells. You may be asked to complete this once, or possibly at multiple visits depending on the study's design. The study is observational, meaning researchers will simply observe and measure—they are not testing a new medication or asking you to change your treatment.
