Overview

The goal of this observational study is to gain deeper insights into human macrophages and vitamin D, and their interplay, within Idiopathic Pulmonary Fibrosis (IPF). The overall questions, it aims to answer, are the following: Do IPF patients suffer from systemic and local (pulmonary) insufficient levels of vitamin D? Do IPF patients suffer from pro-fibrotic and pro-inflammatory pulmonary macrophages?

Primary outcome measures
